Dear Mr. Thornburg;
September 28, 2021
Please consider this information for an application for a single-family residence (SFR)
wastewater irrigation system. The property is located on Abilene Road in Concord, NC.
A physical address has not yet been assigned for this property. An AdvanTex treatment
system with non -discharge surface drip irrigation has been designed for the property.
The AdvanTex treatment system and dripfield are designed for a three -bedroom single
family residence (360 gpd).
Please Note the Following:
This application is being submitted in conjunction with an application titled as the
"Carter Property." The intent of the current property owners, Craig Allan Carter &
Shannon Barringer Carter, is to subdivide a portion of the property to allow for a
residence and non -discharge drainfield for Daniel W. Downey & Kami J. Downey.
Appendix E of this letter includes a document indicating the intent to transfer the
subdivided land to the Downeys. The system design drawings indicate the proposed
property lines.
At this time, the final subdivision and creation of the new lot has not been recorded. The
concern of the property owner was that the property would not be subdivided if the non -
discharge wastewater permits were not able to be granted. Realizing that a permit can not
be issued to a non -recorded lot, I would ask that the review of the application takes place
with the proposed property lines. Once all foreseen issues are addressed through the
normal review process and it is expected that a permit could be issued for each property,

we will complete the recordation and lot creation. At that time, we will update the
application information for final submittal. Once the updated property and application
information is submitted and the Department completes the final reviews, we would hope
the permits would be issued.
The following information is included for your review (with the assumption of utilizing
the proposed property lines).
Section A: Cover Letter
- Included as this letter.

Soil Suitability for Single -Family Residence Wastewater Irrigation Systems
Abilene Road, Concord, NC. 28025
Cabarrus County (PIN: 55498193060000)
PREPARED FOR: Dan Downey, Applicant
PREPARED BY: Christopher McGee, LSS
Senior Soil Scientist
Trevor Hackney, Environmental
Scientist
DATE: August 16, 2021
Agri -Waste Technology, Inc. (AWT) was contracted by the Downey family to provide LSS
permitting assistance for a single-family residence wastewater irrigation system for the property
located on Abilene Road, Concord, NC. A three -bedroom single-family residence is proposed
for construction on the property. Municipal wastewater services are not available; therefore, on -
site wastewater disposal will be required. The property will also require the installation of a
private well. The following report and attachments summarize the findings of the evaluations
performed by AWT from March through May 2021. A preliminary soil evaluation, a detailed soil
evaluation, and Hydraulic Conductivity (KSAT) tests were performed on the property.
Referenced property maps (provided by Cabarrus County GIS) and the recorded plot plan are
included in Attachment 1.
The 6.97-acre tract was evaluated to construct a new 3-bedroom single family residence. The
majority of the property is currently wooded and has been used for agricultural pine tree harvest.
There is a drainage feature in the southern portion of the property that directs water to the
Southwest. The topography/landscape position for wastewater systems is generally favorable at
the far southeastern end of the lot. The slopes range from 3-10% on this property.
Soils on the property are unsuitable for any subsurface on -site wastewater system; therefore, a
surface application system will be required. The property has been denied a septic system permit
for a single-family residence by Cabarrus County Environmental Health Department. A copy of
the denial should be included with the full engineering package for the proposed system.
25

After conducting the preliminary evaluation of the entire property, an area in the southeastern
corner of the property was selected for a surface irrigation system. This area was selected due to
existing soils being most favorable within this zone (deeper indications of saturation). AWT's
evaluation map is included in Attachment 2. Due to the size of the lot and the amount of usable
area, drip dispersal will be required.
The drawing in Attachment 3 details the locations of the relevant site features/setbacks, proposed
soils area for irrigation, a deep soil boring, and saturated hydraulic conductivity (KSAT) test
locations. The USDA NRCS mapped soil type for the proposed irrigation area is Enon series. It
is AWT's opinion that the soils in this area are similar to a typical Enon series. In general, soil
characteristics within the proposed system utilization area were consistent and no significant
inclusions or deviations from this mapped soil type were noted in any borings within the
proposed irrigation area by AWT. Numerous borings were performed throughout the area, with
the major limitation for wastewater utilization being depth to expansive clay mineralogy and
seasonal high-water table (SHWT). In general, the depth to SHWT was 12+ inches throughout
the proposed area of utilization.
Topography and surrounding drainage are favorable in the area selected for irrigation. There are
no significant areas of disturbance other than occasional small depressions. The written
descriptions of borings performed at each KSAT test location, and a deep soil boring are
included in Attachment 4. A standard soil fertility sample was obtained for the surface horizon
and is included in Attachment 5.
Saturated Hydraulic Conductivity (KSAT) Tests
A total of three KSAT tests were conducted during the field work phase of the project. The
purpose of these tests was to determine permeability within the most restrictive soil horizon
(Generally the Bt horizons). The depth to this horizon varied depending on landscape position
and desire to keep the test water column retained within the most limiting zone. All tests were
performed with a Johnson Permeameter. The results are summarized below. The calculation
sheets and any supporting documents are included in Attachment 6. Results have been rounded
to three decimal places.

Loading Rate and Dripfield Computations and Recommendations
Based on the KSAT data, a permeability rate of 0.007 in/hr (geometric mean of the 3 KSAT
measurements) is recommended to be used in the water balance computation for this system.

26

The wastewater irrigation rate shall be determined using the above KsaT data in accordance with
the Single -Family Residence Wastewater Irrigation System Loading Rate Calculation Policy and
the Single -Family Residence Loading Rate Workbook. Due to the variation in the data and
existing site conditions, we recommend a drainage coefficient of 0.40 not be exceeded. The
instantaneous application rate should not exceed 0.20 in/hour. The surface soil texture and
vegetation should allow adequate infiltration at this rate. Local precipitation data should be
considered as part of the loading rate workbook.
As part of the water balance, the approximate land area required for an irrigation system is
calculated based on the size of the proposed residence and the loading rate of the soil. Based on
AWT's soil mapping of the proposed utilization area, approximately 18,400 sq. ft. of usable area
is available for the dripfield (less area is available if the 50 ft. property line setback to the
southeast is not waived). The recommended annual hydraulic loading rate is 15.17 inches per
year or less. We are maintaining a suggested rate within SFR Group "C". The area evaluated and
suitable area for the proposed system is greater than this minimum size which should allow
optimal placement of the dripfield tubing and some flexibility during installation.
AWT is not requiring fill soil to be added to the site in order to meet permit requirements;
however, small isolated spots with ruts or depressions may require pockets of fill (to be field
determined by contractor). Natural topography is ideal to shed surface water, and this will not be
adjusted.
Fill specs:
The use of suitable fill soil may be required in these isolated spots. Final determination will be made by
the contractor and soil scientist. Low areas should be filled so that no water collects or ponds. Allowance
should be made for settling of the soil. The present soil surface texture is sandy loam and offers a good
infiltrative surface. Fill material shall have the following characteristics:
1) Coarse fragments as defined by USDA (2 mm to 3. 0 inches) shall not exceed 10% by volume
of the volume of the fill material.
2) Fill material shall not contain more than 5% organic matter (including leaf debris, twigs,
sticks, etc.)
3) Fill material shall not include any construction debris such as bricks, concrete, construction
wood materials, or any components or fragments of such.
4) Fill material shall classify under one ofthe following USDA soil texture classes: sandy loam,
loam, or silt loam. Particle size analysis may be confirmed by a third party testing laboratory if
necessary.
5) Light tillage of the fill with the topsoil should occur if compaction is a concern, however, this
tillage should not exceed 6 inches below the natural soil surface. Removal of existing vegetation
prior to fill addition is necessary to allow a good gradation between fill and present soil surface.
The contractor should ensure that proper seeding and compaction practices are followed.
Summary and Design Considerations:
AWT is recommending a surface drip irrigation system to serve the proposed single-family
residence. The proposed system must satisfy the design criteria outlined in 15A NCAC 02T
.0605.

1.0. General Project Specifications
1.1 Project Description
The purpose of the project is to install a wastewater treatment system and surface dripfield to
accommodate wastewater from a three -bedroom single-family residence. The treatment system will
consist of a septic tank, an AdvanTex Treatment unit with integral recirculation tank, UV
disinfection, pump tank, irrigation headworks, and a control panel. The surface drip irrigation
system covers approximately 0.41 acres.
1.2 Site Description
The project site consists of property located on Abilene Road, Concord, NC in Cabarrus County.
The residence and treatment components will be located to the east of Abilene Road in the
northern portion of the property. The dripfield will be located on the southern side of the
property. With the location of the drainfield, setback waivers were considered for this property.
The location of the treatment unit and dripfield are shown on the system drawings.
1.3 Adjacent Property
The surrounding area at the residence site is rural and occupied by primarily undeveloped land and
single-family residences and a school. The dripfield is to be located a minimum of 100' from any
off -site residence, 100' from any surface water body, and 50' from any property line or public right-
of-way (except for the property line directly north of the drainfield which has been waived).
1.4 Soils and Water Table
The soil in the project area is predominately mapped in the Enon series and is above the groundwater
table. In general, depth to the seasonal high-water table is 10-15 inches throughout the proposed
area for the drainfield.
63

2.0. Material Management Practices
The following are the material management practices that will be used to reduce the risk of spills and
other accidental exposure of materials and substances to storm water runoff
2.1 Housekeeping
The following good housekeeping practices will be followed on site during the construction project.
• An effort will be made to store only enough product required to do the job.
• All materials stored on site will be stored in a neat orderly manner in their appropriate containers
and, if possible, under a roof or other enclosure.
• Products will be kept in their original containers with the original manufacturer's label.
• Substances will not be mixed with one another unless recommended by the manufacturer.
• Whenever possible, all of a product will be used before disposing of the container.
• Manufacturer's recommendations for proper use and disposal will be followed.
• The site superintendent will inspect daily to ensure proper use and disposal of materials on site.
2.2 Hazardous Products
These practices are used to reduce the risks associated with hazardous materials:
Products will be kept in original containers unless they are not re -sealable.
Original labels and Material Safety Data Sheets (MSDS) will be retained as they provide
important product information.
If surplus product must be disposed of, the manufacturer's or local and state recommended
methods for proper disposal will be followed.
2.3 Product Safety Practices
The following product safety practices will be followed on site:
2.3.1 Petroleum Products
All on site vehicles will be monitored for leaks and receive regular preventive maintenance to reduce
the chance of leakage. Petroleum products will be stored in tightly sealed containers which are clearly
labeled.
2.3.2 Fertilizers
Fertilizers used will be applied at recommended agronomic rates. Once applied, fertilizer will be
worked into the soil to limit exposure to storm water. The contents of any partially used bags of
fertilizer will be transferred to a sealable plastic bin to avoid spills.
64

2.4 Spill Control Practices
The following practices will be followed for spill prevention and cleanup:
• Manufacturer's recommended methods for spill cleanup will be clearly understood and site
personnel will be made aware of the procedures and the location of the information and cleanup
supplies.
• Materials and equipment necessary for spill cleanup will be kept in the material storage area on
site. Equipment and materials will include but not be limited to brooms, dust pans, mops, rags,
gloves, goggles, kitty litter, sand, sawdust, and plastic and metal trash containers specifically for
this purpose.
• All spills will be cleaned up immediately after discovery.
• The spill area will be kept well ventilated and personnel will wear appropriate protective clothing
to prevent injury from contact with a hazardous substance.
• Spills of toxic or hazardous material will be reported to the appropriate state or local government
agency, regardless of size.
• The spill prevention plan will be adjusted to include measures to prevent this type of spill from
reoccurring and how to clean up the spill if there is another one. A description of the spill, what
caused it, and the cleanup measures will also be included.
• , the site superintendent responsible for the day-to-day site operations, will
be the spill prevention and cleanup coordinator. He will designate at least other site
personnel who will receive spill prevention and cleanup training. These individuals will each
become responsible for a particular phase of prevention and cleanup.
65

3.0. Site Work
The site shall be maintained in an orderly and clean fashion. Debris should be confined to a common
area and removed weekly. The minimum area needed shall be disturbed. Due to the small footprint
of the project, a formal erosion and control plan has not been developed. However, contractor shall
follow standard practices to minimize any adverse effects from the installation of the system.
3.1 Construction Roads and Parking
Construction roads and parking areas are to be inspected periodically for condition of surface. Top -
dress with new gravel as needed. Check areas for erosion and sedimentation after runoff -producing
rains. Maintain all vegetation in a healthy, vigorous condition. Sediment -producing areas should be
treated immediately.
3.2 Tree Preservation and Protection
Some clearing of trees will be required for the installation of the drain line connecting the facility to
the treatment unit. Care shall be taken to minimize the disturbed area during installation. In spite of
precautions, some damage to protected trees may occur. In such cases, repair any damage to the
crown, trunk, or root system immediately.
- Repair roots by cutting off the damaged areas and painting them with tree paint. Spread peat
moss or moist topsoil over exposed roots.
- Repair damage to bark by trimming around the damaged area as shown in Figure I below,
taper the cut to provide drainage, and paint with tree paint.
- Cut off all damaged tree limbs above the tree collar at the trunk or main branch. Use three
separate cuts as shown in Figure 2 to avoid peeling bark from healthy areas of the tree.

tree.
To the degree possible, the vegetation that is removed during the drain line installation shall be
shredded on site and used to cover the drain line installation. Larger material shall be removed from
the site and disposed of properly.
67

3.3 Removal of Topsoil
MATERIALS
Determine whether the quality and quantity of available topsoil justifies selective handling. Quality
topsoil has the following characteristics:
Texture- loam, sandy loam, and silt loam are best; sandy clay loam, silty clay loam, clay loam,
and loamy sand are fair. Do not use heavy clay and organic soils such as peat or muck as
topsoil.
- Organic matter content- (sometimes referred to as "humic matter") should be greater than
1.5 % by weight.
- Acidity- pH should be greater than 3.6 before liming, and liming is required if it is less than
6.0.
- Soluble salts- should be less than 500 ppm.
- Sodium- sodium adsorption ratio should be less than 12. The depth of material meeting the
above qualifications should be at least 2 inches. Soil factors such as rock fragments, slope,
depth to water table, and layer thickness affect the ease of excavation and spreading of
topsoil. Generally, the upper part of the soil, which is richest in organic matter, is most
desirable; however, material excavated from deeper layers may be worth storing if it meets the
other criteria listed above. Organic soils such as mucks and peats do not make good topsoil.
They can be identified by their extremely light weight when dry.
STRIPPING
Strip topsoil only from those areas that will be disturbed by excavation, filling, road building, or
compaction by equipment. A 4-6 inch stripping depth is common, but depth varies depending on the
site. Determine depth of stripping by taking soil cores at several locations within each area to be
stripped. Topsoil depth generally varies along a gradient from hilltop to toe of the slope. Put sediment
basins, diversions, and other controls into place before stripping.
STOCKPILING
Select stockpile location to avoid slopes, natural drainage ways, and traffic routes (also applies to fill
soil stockpiles). Re -spreading is easier and more economical when topsoil is stockpiled in small piles
located near areas where they will be used.
Sediment barriers- Use sediment fences or other barriers where necessary to retain
sediment.
Temporary seeding- Protect topsoil stockpiles by temporarily seeding as soon as possible,
no more than 21 calendar days after the formation of the stockpile
Permanent vegetation- If stockpiles will not be used within 90 days they must be stabilized
with permanent vegetation to control erosion and weed growth.
SITE PREPARATION
Before spreading topsoil, establish erosion and sedimentation control practices such as diversions, and
berms as needed.
68

Grading- Maintain grades on the areas to be topsoiled according to the approved plan and do
not alter them by adding topsoil.
Limit of subsoil- Where the pH of the existing subsoil is 6.0 or less, or the soil is composed
of heavy clays, incorporate agricultural limestone in amounts recommended by soil tests or
specified for the seeding mixture to be used. Incorporate lime to a depth of at least 2 inches
by disking or raking.
Roughening- Immediately prior to spreading the topsoil, loosen the subgrade by disking or
scarifying to a depth of at least 4 inches, to ensure bonding of the topsoil and subsoil. If no
amendments have been incorporated, loosen the soil to a depth of at least 6 inches before
spreading topsoil.
SPREADING TOPSOIL
Uniformly distribute topsoil to a minimum compacted depth of 2 inches. Do not spread topsoil while
it is frozen or muddy or when the subgrade is wet or frozen. Correct any irregularities in the surface
that result from topsoiling or other operations to prevent the formation of depressions or water
pockets. Compact the topsoil enough to ensure good contact with the underlying soil, but avoid
excessive compaction, as it increases runoff and inhibits seed germination. Light packing with aroller
is recommended where high -maintenance turf is to be established.
On slopes and areas that will not be mowed, the surface may be left rough after spreading topsoil. A
disk may be used to promote bonding at the interface between the topsoil and subsoil. After topsoil
application, follow procedures for seedbed preparation, taking care to avoid excessive mixing of
topsoil into the subsoil.
3.4 Addition of Fill Material
MATERIALS
To maintain a consistent separation depth to SHWT conditions, some fill soil will be required in
low/rutted spots within the proposed utilization areas. Natural topography is ideal to shed surface
water, and this will not be adjusted.
Up to 6 inches of suitable fill soil may be required in these isolated spots. Final determination will
be made by the contractor and soil scientist. Low areas should be filled so that no water collects
or ponds. Allowances should be made for settling of the soil. The present soil surface texture is
sandy loam and offers a good infiltrative surface. Fill material shall have the following
characteristics:
1) Coarse fragments as defined by USDA (2 mm to 3.0 inches) shall not exceed 10% by
volume of the volume of the fill material.
2) Fill material shall not contain more than 5% organic matter (including leaf debris,
twigs, sticks, etc.)
3) Fill material shall not include any construction debris such as bricks, concrete,
construction wood materials, or any components or fragments of such.
M

4) Fill material shall classify under one of the following USDA soil texture classes: sandy
loam, loam, or silt loam. Particle size analysis may be confirmed by a third -parry testing
laboratory if necessary.
5) With 6 inches of fill added in low-lying or rutted areas, the depth to SHWT will allow
buffer to maintain minimum depth to SHWT of 12 inches after installation and operation.
Light tillage of the fill with the topsoil should occur if compaction is a concern, however,
this tillage should not exceed 6 inches below the natural soil surface. Removal of existing
vegetation prior to fill addition is necessary to allow a good gradation between fill and
present soil surface.
It is recommended that borings be performed in spots which are filled to confirm adequate SHWT
separation upon completion of installation and prior to start-up. The contractor should ensure
that proper seeding and compaction practices are followed.
APPLICATION
Specific fill application details may vary from site to site, for this site:
1) Vegetation 8" or less in diameter shall be removed by hand or with small tracked
equipment to prevent native soil loss and compaction.
2) Provide sufficient fill to achieve 12" separation to the SHWT.
3) Fill is to be applied in multiple lifts if necessary.
4) Light tillage of the fill with the topsoil should occur, however, this tillage should not
exceed 4 inches below the natural soil surface.
5) Extend fill material 5 feet beyond the wetted area and blend into the natural contours.
6) Compact the fill material to 1.1-1.3 g/cm3.
7) Surface shall be graded to a final grade that matches the natural grade to provide uniform
drainage.
8) No site work shall be done when the conditions are wet, to avoid excess compaction.
9) Avoid placing fill material around large trees to prevent tree death (an arborist can provide
more guidance on tree protection).
10) Field shall be seeded with temporary vegetation suitable for the specific time of year. If
construction is complete in the following windows, permanent seeding can take place
immediately: February 15 through April 15, or September 15 through November 15. Once
final fill has been placed, a soil fertility sample shall be taken. Seeding can occur
immediately with the following amendments:
Ag-Lime: 280-300 pounds
10-10-10 Fertilizer: 51 pounds
The soil test recommendations will be used to supply additional amendments as needed.
Temporary seeding shall include the following species and rates: Annual ryegrass or
ryegrass blend with other small grains, at 10 pounds per 1000 square feet, lightly tilled or
raked into the top 0.5-1.0 inch of topsoil, cultipack or roll lightly, and cover with straw or
other shade cover. Follow with permanent fescue seeding in the appropriate dates, with
the September 15- October 15 window preferred.
FERTILITY ANALYSIS
70

Upon addition of the fill, a soil sample will be taken for fertility analyses. Soil test recommendations
will be followed for pH adjustment and nutrient amendments for N, P, and K to help with grass
establishment. Soil amendments may be applied pre or post construction.
3.5 Permanent Seeding
3.5.1 SEEDBED REQUIREMENTS
Establishment of vegetation should not be attempted on sites that are unsuitable due to inappropriate
soil texture, poor drainage, concentrated overland flow, or steepness of slope until measures have
been taken to correct these problems.
To maintain a good stand of vegetation, the soil must meet certain minimum requirements as a growth
medium. The existing soil should have these criteria:
- Enough fine-grained (silt and clay) material to maintain adequate moisture and nutrient supply
(available water capacity of at least .05 inches of water to 1 inch of soil).
- Sufficient pore space to permit root penetration.
- Sufficient depth of soil to provide an adequate root zone. The depth to rock or impermeable
layers such as hardpans should be 12 inches or more, except on slopes steeper than 2:1 where
the addition of soil is not feasible.
- A favorable pH range for plant growth, usually 6.0-6.5.
- Freedom from large roots, branches, stones, large clods of earth, or trash of any kind. Clods
and stones may be left on slopes steeper than 3:1 if they are to be hydroseeded.
If any of the above criteria are not met (i. e., if the existing soil is too coarse, dense, shallow, or acidic
to foster vegetation) special amendments are required. The soil conditioners described below may be
beneficial.
3.5.2 SOIL CONDITIONERS
In order to improve the structure or drainage characteristics of a soil, the following materials may be
added. These amendments should only be necessary where soils have limitations that make thempoor
for plant growth or for fine turf establishment.
- Peat Appropriate types are sphagnum moss peat, hypnum moss peat, reed -
sedge peat, or peat humus, all from fresh -water sources. Peat should
be shredded and conditioned in storage piles for at least 6 months after
excavation.
- Sand clean and free of toxic materials.
- Vermiculite horticultural grade and free of toxic substances.
- Rotted manure stable or cattle manure not containing undue amounts of straw or
other bedding materials.
3.5.3 SEEDBED PREPARATION
71

Complete grading according to the approved plan before seeding. Below are steps to take in order to
prepare the seedbed for planting.
• Chisel compacted areas and spread topsoil 3 inched deep over adverse soil conditions, if available.
• Rip the entire area to 6 inches deep.
• Remove all loose rock, roots, and other obstructions leaving surface reasonably smooth and
uniform.
• Apply agricultural lime, fertilizer, and superphosphate uniformly and mix with soil (section 4.6).
• Continue tillage until a well pulverized, firm reasonably uniform seedbed is prepared 4 to 6 inches
deep.
• Seed on a freshly prepared seedbed.
• Mulch immediately after seeding and anchor mulch (section 8.3).
Apply lime and fertilizer evenly and incorporate into the top 4-6 inches of soil by disking or other
suitable means. Operate machinery on the contour. When using a hydroseeder, apply lime and
fertilizer to a rough, loose surface.
Roughen surfaces. Complete seedbed preparation by breaking up large clods and raking into a
smooth, uniform surface. Fill in or level depressions that can collect water. Broadcast seed into a
freshly loosened seedbed that has not been sealed by rainfall.
3.5.4 SEEDING
Seeding dates given in the manufacturer's seeding mixture specifications are designated as "best" or
"possible". Seedings properly carried out within the "best" dates have a high probability of success.
It is also possible to have satisfactory establishment when seeding outside these dates. However, as
you deviate from them, the probability of failure increases rapidly. Seeding on the last date shown
under "possible" may reduce chances of success by 30-50%. Always take this into account in
scheduling land -disturbing activities.
Use certified seed for permanent seeding whenever possible. Certified seed is inspected by the North
Carolina Crop Improvement Association. It meets published North Carolina Standards and should
bear an official "Certified Seed" label.
Labeling of non -certified seed is also required by law. Labels contain important information on seed
purity, germination, and presence of weed seeds. Seed must meet State standards for content of
noxious weeds. Do not accept seed containing "prohibited" noxious weed seed.
Apply seed uniformly with a cyclone seeder, drop -type spreader drill, cultipacker seeder, or
hydroseeder on a firm, friable seedbed.
When using a drill or cultipacker seeder, plant small grains no more than 1 inch deep, grasses and
legumes no more than 2 inch. Equipment should be calibrated in the field for the desired seeding rate.
When using broadcast -seeding methods, subdivide the area into workable sections and determine the
amount of seed needed for each section. Apply one-half the seed while moving back and forth across
72

the area, making a uniform pattern; then apply the second half in the same way, but moving at right
angles to the first pass (Figure 13).
Cover broadcast seed by raking or chain dragging; then firm the surface with a roller or cultipacker to
provide good seed contact.
3.5.5 IRRIGATION
Moisture is essential for seed germination and seedling establishment. Supplemental irrigation can be
very helpful in assuring adequate stands in dry seasons or to speed development of full cover. Assess
the need for irrigation when the seeding is conducted.
Water application rates must be carefully controlled to prevent runoff. Inadequate or excessive
amounts of water can be more harmful than no supplemental water.
3.5.6 MULCHING
Mulch all plantings immediately after seeding. Select a material based on site and practice
requirements, availability of material, labor, and equipment. Table 6.14a lists commonly used mulches
and some alternatives.
Before mulching, complete the required grading, install sediment control practices, and prepare the
seedbed. Apply seed before mulching except in the following cases:
- Seed is applied as part of a hydroseeder slurry containing wood fiber mulch.
- A hydroseeder slurry is applied over straw.
3.5.7 APPLICATION OF ORGANIC MULCH
Organic mulches are effective where they can be tacked securely to the surface.
Spread mulch uniformly by hand, or with a mulch blower. When spreading straw mulch by hand,
divide the area to be mulched into sections of approximately 1,000 ftZ, and place 70-90 lb of straw (1
to 2 bales) in each section to facilitate uniform distribution (See Table below). After spreading mulch,
no more than 25% of the ground surface should be visible. In hydroseeding operations, a green dye,
added to the slurry, assures a uniform application.
3.5.8 ANCHORING ORGANIC MULCH
Straw mulch must be anchored immediately after spreading using vegetation.
Rye (grain) may be used to anchor mulch in fall plantings, and German millet in spring. Broadcast at
15 lb/acre before applying mulch.
3.5.9 PERMANENT STABILIZATION
Permanent stabilization is needed in graded or cleared areas subject to erosion and where a
permanent, long-lived vegetative cover is needed. Typically, disturbed portions of a site where
construction activities have permanently ceased will be stabilized with permanent seeding no later
than 14 days after the last construction activity. This method will not provide erosion control cover
or prevent soil slippage on soils that are not stable due to soil texture or structure, water movement
73

or excessively steep slopes. In some areas, it may be necessary to install erosion or sediment control
practices such as dikes, contour ripping, erosion stops, channel liners, sediment basins, diversions,
subsurface drainage, or other practices.
Prior to seeding, 1,000 lbs/ac of a 12-12-12 or equivalent fertilizer and lime according to soil test or
in lieu of soil test, 4,000 lbs/ac of ground agricultural limestone shall be worked into the soil to a
depth of 3 inches.
Seed should be applied uniformly at a depth of 1/4 to 2 inch with appropriate equipment. Except on
very flat slopes and ideal seeding conditions, small grain straw should be applied at a rate of 3,000 to
4,000 lbs/ac using appropriate mulch anchoring techniques. Other mulch materials can be used
except under adverse conditions or steep slopes; grain straw should be adequate.

PVC Riser Installation
Installing PVC Access Risers onto Cast -In Orenco® Riser -Tank Adapters
Access risers provide access to septic tank openings, simplifying inspection and maintenance procedures. Access riser -to -tank connections
must be watertight for the proper functioning of an onsite septic system or effluent sewer system. Orenco strongly recommends watertightness
testing of all access riser -to -tank connections after installation.
Following are instruction sets for prepping and installing access risers, installing grommets, and selecting adhesives for riser installations.
Refer to the chart below to determine which instruction set to use.

Instruction Set 1: Riser Preparation
Step 1: Determine Riser Height
Determine how high the riser needs to be.
• The top of the riser should be about 3 inches (75 mm) above finished grade
after installation and backfilling —This allows 2 inches (50 mm) for tank
settling and 1 inch (25 mm) for ensuring drainage away from the riser.
Step 2. Cut Riser to Size (if Necessary)
If the riser needs to be cut to size, cut it with a circular saw or table saw
• Always cut excess length from the bottom of the riser.
• For square, even cuts, a good fit, and a watertight joint between the riser
and the adapter, use an Orenco riser -cutting saw guide.
• To install risers less than 30 inches (760 mm) wide onto 500-gallon
(2000-L) Orenco FRP tanks, cut the riser so it fits into the tank and the
lowest rib rests on the tank's top, as shown.
Step 3. Dry Fit Riser to Adapter
Step 3a: Dry fit the riser to the adapter.
• Make sure riser penetrations are the right sizes and in the correct locations.
Step 3b: If the riser is higher than 3 inches (75 mm) above the estimated final
grade, cut it to size per the instructions in Step 2.
Step 3c: If the riser is too short, use an Orenco grade ring to extend it.

Instruction Set 2: Grommet Installation
Step 1: Mark Access Riser
Step 1a: Use the site plans or drawings to find out if riser penetrations are needed
Step 1 b: Use the plans or drawing to mark the locations of the penetrations.
• If plans or drawings aren't available, use Drawing 1 b as a general guide
for locating riser penetrations.
Step 2: Drill Holes and Clean Access Riser
Step 2a: Drill holes for riser penetrations.
• If you have questions about where to locate various riser penetrations,
contact your Distributor for more information.
Using Orenco® RKHS Hole Saws ...
Cut the hole and grind the ribs down to make a flat, smooth surface for
installing the grommet.
• Make sure your hole saw is the correct size and your drill is at least 18 volts.
• Don't grind too deeply — about 1/16 inch (1.6 mm) is deep enough.
Using Standard Hole Saws ...
1: Use the correctly sized hole saw to cut a hole, centered on the mark.
2: Trim the riser ribs back 1 inch (25 mm) from around the hole.
• Use a grinder or cutting tool to notch the ribs through to the riser wall.
• Use a hammer and chisel to break off the notched rib sections.
• Use a grinder to make a flat, smooth surface around the hole.
Step 2b: Clean and deburr the hole and flat surface with a wire brush and
deburring knife or tool.
• Be careful not to enlarge the penetration.
Step 3: Install Grommet
Step 3a: Apply a bead of adhesive to the groove in the grommet's outer diameter.
• For adhesive recommendations, see Instruction Set 7.
Step 3b: Firmly press the grommet into the penetration.

Step X Use a tongue depressor, putty knife, or clean cloth to make a good
fillet over the seams.
Note: If cold weather conditions or frost heave are a concern at the site, contact
a qualified engineer or Orenco for additional recommendations on installing ribbed
PVC risers.
IMPORTANT Orenco strongly recommends that all tank risers 12-in. (300-mm)
and larger in diameter be equipped with riser safety grates to help prevent
accidental or unauthorized entry.
Step 4: Test Riser Watertightness
Follow Instruction Set 6 of this document for testing the riser's watertightness.
Note: Watertight connections are critical for the wastewater system to function
effectively and efficiently.

Instruction Set 6: Riser Watertightness Testing
IMPORTANT A watertight tank and watertight riser -to -tank connections are
critical for the wastewater system to function effectively and efficiently.
Step 1: Prep for Test
Step 1a: Make sure the adhesive seams have set and the tank has been backfilled
according to the manufacturer's instructions — typically to the tank's midpoint.
Step 1b: Plug the inlet (and outlet, if present) of the tank with watertight plugs.
Step 1c: Fill the tank with water to a level 2 inches (51 mm) into the riser.
Step 2: Test Watertightness
Step 2a: Wait for the required time before inspecting the riser -to -tank
connections for leakage.
• Follow the tank manufacturer's recommendations (or applicable local regula-
tions) for wait times before inspecting the tank for leaks.
• Orenco recommends at least 30 minutes for its fiberglass tanks.
Step 2b: Check for any drop in the liquid level inside of the riser and any visible
leakage from the riser -to -tank connections.
• At the end of the test, there should be no drop in liquid level and no visible
leakage from seams, pinholes, or other imperfections.
• If leaks are found during the test, seal the leaks and repeat the test.
Step 2c: Once the riser -to -tank connections are proven watertight, remove the
plug(s) and drop the water level in the tank to just below the invert of the inlet or
outlet, whichever is lower.

Drenco° DuraFiber" Access Lids provide a secure, damage -resistant
covering for ribbed PVC and HDPE risers, pump basins, and access
ports. They are not recommended for vehicular traffic. 24-inch (600-mm)
DuraFiber lids require an RLA24 adapter to mate to 24-inch (600-mm)
Perma-LOCTI pipe. 30-inch (750-mm) DuraFiber lids are not compatible
with 30-inch (750-mm) RLA Riser -Lid -Adapters or 30-inch (750-mm)
Perma-Loc pipe. For these products, use Drenco's FLF-Series lids.
General
DuraFiber Access Lids are constructed of resin -infused fiberglass fabrics
for extreme durability and damage resistance, with breaking strengths in
excess of 20,000 pounds (9,000 kg).
They feature flat -style flanges for easier access, allowing clean, flush -to -
grade installations. They have cored centering rings for aligning lids with
risers. They also have urethane gaskets to help provide watertight seals.
DuraFiber Lids feature a non-skid surface for better grip and aesthet-
ics, a molded -in caution statement, and room for a customer logo. They

Biotubeg Effluent Filters
Installation, Operation and Maintenance Instructions
FT08 Models and All Base Inlet Models
U.S. Patent Nos. 5294635 / 4439323
Installation Instructions:
The Biotube Effluent Filter is suspended in the septic tank by the 4" outlet pipe. The filter is composed of a
vault body that will be fixed to the discharge pipe and a removable cartridge that consists of the Biotube
filter cartridge and the extendible handle.
1. Test -fit the effluent filter on the 4" out-
let pipe without gluing. Make sure that
it fits plumb.
Any existing outlet tee will have to be
removed.
2. Ensure sufficient clearance for trouble -
free servicing of filter cartridge. Install
assembly near the tank wall to reduce
any stresses that may be caused by
maintenance.
Sufficient room between the access
port and filter should be provided for
easy removal of solids from the tank.
The cartridge will need to be removed
and cleaned while the tank's solids
content is being pumped -out.

3. Once the filter has been fitted properly,
apply primer and PVC cement to the
outside of the outlet pipe and the filter's
4" outlet. Use a multipurpose cement if
the outlet pipe is ABS. Do not use
primer on ABS.
Optional: Stainless steel set screws
may be used instead of glue.
4. Slide the effluent filter onto the 4" pipe
and plumb vertically.
5. Hold the filter in position until the adhe-
sive has time to set (approximately 20
seconds).
6. Extend the handle of the cartridge to an
elevation above the top of the tank for
easy access. Use 3/4" schedule 40 PVC
for extension.
Either use the stainless steel set
screws or glue the extensions in place.

In existing tanks or in tanks with poorly
located access ports, it may be
necessary to extend the tank outlet
fitting by using a coupling.
A coupling may also be needed to
bush from 3034 PVC to the schedule
40 outlet of the filter.
Maintenance Instructions:
1. Remove the filter cartridge by lifting it
out of the vault.
2. Spray the cartridge tubes with a hose
to remove material sticking to them.
Make sure the rinse water runs back
into the tank.
3. Inspect the vent hole and modulating
orifices. Spray them clear of any
debris.
Replace the cartridge. Be sure to snap
the cartridge back into the saddle holes
at the top of the cartridge vault.

• Repairs and retrofits
• Small sites and poor soils
• Sites that require shallow bury
Product image is for illustrative purposes only.
General
Following a septic tank equipped with a Biotube° effluent filter, the
AdvanTex AX-RT unit eliminates the need for separate recirc, treat-
ment, and discharge tanks by performing all functions within a single
module. It also reduces the number of risers and lids needed in the
treatment train. For sites requiring antibuoyancy measures, Orenco
offers antifloatation kits with turnbuckles.
The heart of the system is the AdvanTex Recirculating Treatment Tank,
a sturdy, watertight, corrosion -proof fiberglass tank that includes the

Septic Tanks Used in AX-RT Treatment Systems
Be sure that any septic tank used in an AX-RT Treatment System meets the following conditions:
• The tank must conform to an approved and authorized tank design for AdvanTex Systems, and it must meet all applicable regula-
tory requirements (no pour -in -place tanks, no homemade tanks, etc.). Call your local Dealer for specifics.
• The tank must be structurally sound.
• The tank must have at least 1000 gal. (3800 L) capacity for an AX20-RT, 1250 gal. (4730 L) for a 5-bedroom AX25-RT, and 1500
gal. (5680 L) for a 6-bedroom AX25-RT at the normal operating level (below the invert of the outlet).
• The tank must have an at -grade access with a watertight, securable and removable lid. If it doesn't, an at -grade access must be
installed onto the septic tank and be made watertight.
• The tank must be watertight and free of leaks.
• An Orenco effluent filter (model FTSO444-36V, FTW0444-36V, or FT0822-14B) must be installed in the septic tank.
QKey Point: For existing septic tanks — the tank's depth of burial must allow for a minimum fall of 1/8 inch per foot (10 mm
per meter or 1 %) from the septic tank's invert of outlet to the AX-RT unit's invert of the inlet. If sufficient fall cannot be met, a
grade ring extension must be installed on the AX-RT or a pumping system will need to be installed in the septic tank to move
the filtered effluent to the AX-RT unit. (Contact your Dealer for assistance.)

Raw sewage enters the septic tank through its inlet tee. In the septic tank, the raw sewage separates into a scum layer, a sludge layer,
and a clear zone. Effluent from the clear zone passes through a Biotube° Effluent Filter and is discharged to the recirc/blend chamber
of the AX-RT unit. The effluent flows through the recirc transfer line to the recirc pumping system, which pumps filtered effluent to the
distribution manifold in the top of the unit. Effluent percolates down through the textile media and is divided — by means of a tank baffle
— between the recirc/blend chamber and the recirc/filtrate chamber inside of the unit.
The recirc pumping system's operation is controlled by a timer in the control panel. It allows the pump to dose the textile media for short
periods (usually 40-60 seconds), typically 72 times a day. These frequent "micro -doses," which optimize the treatment process, occur
throughout the day to maintain the proper biological environment.

AX-RT units require 18-24 inches (457-610 mm) space on
all four sides when installed in their own excavation.
Installation Steps
Step 1: Review or Sketch Site Plans
Check the site plan for the specifics of your installation.
QKey Point If you're installing the AX-RT unit more than 20 ft (6 m)
from the septic tank, contact your Dealer for assistance.
Step 1a: Detailed Site Plan Provided
Make sure that the plan accurately reflects conditions at the site. If it
doesn't, contact the Designer before scheduling the installation.
Step 1b: Plan Of Limited Detail Or No Site Plan Provided
If you are installing the AX-RT unit with a plan of limited detail or with no plan,
contact your local Dealer for assistance and then sketch a site plan that is
consistent with the Designer's specifications:
nKey Points.
• Sketch the exact positions of the system components, pipes, electrical
conduits, etc. Account for current and likely future landscape features
in the sketch. (See Panel Installation, EIN-CP-GEN-1, for recommenda-
tions for installing control panels.)
• A minimum fall of 1/8 inch per foot (10 mm per meter or 1%) is required
from the septic tank's invert of outlet to the AX-RT unit's invert of the inlet.
• The invert of the inlet on the AX-RT is 46 in. (1168 mm) up from the
base of the unit. The outlet is 24 in. (610 mm) down from the top of the
unit for pump dispersal or 41.5 in. (1054 mm) down for gravity dispersal.
• The bottom of the AX-RT lid must sit 2 inches (50 mm) above finished
grade when set and level. Standard unit height is 72 inches (1830 mm);
grade rings increase height by 6 or 12 inches (152 or 305 mm).
• If the AX-RT unit is installed in its own excavation, the unit requires
18-24 inches (457-610 mm) of space on all four sides.
• If the AX-RT unit is installed in tandem with the septic tank, a minimum of
2 ft (610 mm) separation distance is required between the unit and tank.
• If the AX-RT unit is being installed parallel to the septic tank, offset the
unit from the tank by 6 ft (1.8 m) if antibuoyancy measures are neces-
sary or 4 ft (1.2 m) if antibuoyancy measures are not necessary.
Step 2. Perform Excavation(s)
Step 2a: Before excavating, consider the necessary elevations, offsets, and
grade requirements for the AX-RT unit and (if needed) the septic tank.
Step 2b: Perform the excavation(s).
nKey Points.
• Follow the manufacturer's recommendations for excavating the tank area.
• A minimum fall of 1/8 inch per foot (10 mm per meter or 1 %) is
required from the septic tank's invert of outlet to the AX-RT unit's invert
of the inlet.

Installation Steps
Step 2. Perform Excavation(s), cont.
Step 2c: Make sure the bottom of the excavation is suitable for setting the
AX-RT unit and (if needed) the tank: stable, smooth, level, and free of debris,
rocks, and other sharp objects.
nKey Points.
• Follow the manufacturer's instructions for bedding the tank.
• If the bottom of the excavation is uneven or rocky, lay a 4-in. (100-mm)
bed of sand or pea gravel and compact the material to create an even,
smooth surface.
Step 2d: If the bottom of the excavation is unstable, stabilize the bottom of
the excavation before continuing.
• For unstable base soil (peat, quicksand, muck, soft or highly expansive clay,
etc.), you may need to over -excavate the site depth and set a firm, 6-in.
(152-mm) compacted base of <_ %z- to <_ 3/4-in. (13- to 19-mm) aggregate
or pea gravel.
• For extremely unstable soil, you may need to pour a concrete layer to
stabilize the bottom of the excavation.
• If you have doubt about the soil's stability, consult a local civil or struc-
tural engineer.
Step 3: Set Septic Tank (if Needed)
Set the septic tank according to the manufacturer's instructions.
• Use Fiberglass Tank Burial instructions (NIN-TNK-1) to install Orenco's
500-gallon through 2000-gallon (2000-L through 7570-L) Fiberglass Tanks.
OIMPORTANT Take care to keep everyone clear of the excavation
when placing the tank.
QKey Points:
• The tank has to be set at the correct depth to connect to the sewage inlet.
• A minimum fall of 1/8 inch per foot (10 mm per meter or 1 %) is required
from the septic tank's invert of outlet to the AX-RT unit's invert of the inlet.
Make sure the excavation is stable, smooth, level, and free
from debris, rocks, and sharp objects.

Lower the AX-RT unit into position.
18-24 in.
(460-600 mm)
12 in. (300 mm)
When using Orenco fiberglass deadmen, be sure to place them
on a small lift of soil 12 inches (300 mm) from the bottom of
the AX-RT.
Installation Steps
Step 4: Set AX-RT Unit
Step 4a: Attach proper lifting equipment to the lifting points on the AX-RT unit.
Step 4b: Carefully lift the unit and lower it into the correct position.
Step 4c: Remove the equipment when the unit is set and level in position.
OIMPORTANT Take care to keep everyone clear of the excavation
when placing the unit. Use a lifting device that will not damage
the unit or the units lid.
QKey Points:
• A minimum fall of 1/8 inch per foot (10 mm per meter or 1%) is required
from the septic tank's invert of outlet to the AX-RT unit's invert of the inlet.
• The bottom of the AX-RT lid must sit 2 inches (50 mm) above finished
grade when set and level.
• If the AX-RT unit is installed in its own excavation, the unit requires
18-24 inches (457-610 mm) of space on all four sides.
• If the AX-RT unit is installed in tandem with the septic tank, a minimum of
2 ft (610 mm) separation distance is required between the unit and tank.
• If the AX-RT unit is being installed parallel to the septic tank, offset the
unit from the tank by 6 ft (1.8 m) if antibuoyancy measures are neces-
sary or 4 ft (1.2 m) if antibuoyancy measures are not necessary.
Step 5: Install Antibuoyancy Deadmen (If Needed)
Determine if antibuoyancy deadmen are necessary for the installation.
Orenco offers antibuoyancy hardware kits that can be used with Orenco
fiberglass deadmen or concrete deadmen.
• Deadmen are recommended for all installations.
• Deadmen are required if there is a potential for groundwater to be pres-
ent in the excavation at any time, or if surface runoff can fill the excava-
tion at any time, resulting in a "bathtub" effect.
Note: This effect occurs in dense soils when water fills an excavation
during surface water runoff —usually during a heavy rain event —
before the disturbed soil in the excavation has had time to settle.
• If you are unsure whether to install antibuoyancy deadmen or not, con-
sult the system Designer or an engineer.
Step 5a: Installing Orenco Fiberglass Deadmen
Step 5a (i): Build up a 3- to 4-inch (75- to 100-mm) lift of soil on each
side of the unit for the deadmen to rest upon.
Step 5a (ii): Secure the deadmen along the length of the unit, on both
sides, with the antibuoyancy kit hardware. Then lower the unit into the hole.
Step 5a (iii): Place the deadmen at least 12 inches (300 mm) from the
bottom of the unit, and make sure they are level.

Installation Steps
Step 5: Install Antibuoyancy Deadmen (If Needed), Cont.
Step 5b: Installing Concrete Deadmen
Notes:
• We recommend preparing concrete deadmen off site before installation.
• PVC forms for concrete deadmen can be made from 12-in. dia. x 4-ft
long (300-mm x 1200-mm long) PVC half -pipe or chamber material.
• Wooden forms for concrete deadmen can be built 12-in. wide x 6 in.
tall x 4 ft long (300-mm x 150-mm x 1200-mm).
Step 5b (i): Fill two forms halfway with concrete.
Step 5b (ii): Place two #4 reinforcing bars in each of the forms.
Step 5b (iii): Finish filling the forms.
Step 5b (iv): Sink eyebolts from the antibuoyancy hardware kit into the
concrete for attaching the deadmen later.
Step 5b (v): Let the concrete set completely before moving the deadmen.
Step 5b (vi): Use appropriate lifting gear to set the deadmen in place.
Step 5b (vii): Secure the deadmen along the length of the unit, on both
sides, with the antibuoyancy hardware kit and make sure they are level.
Step 6: Partially Backfill Excavation(s)
Partially backfill around the AX-RT unit and (if needed) the tank. Follow the
manufacturer's instructions for backfilling around the tank. Follow the steps
below to backfill around the AX-RT unit.
OIMPORTANT Bolt down the AX-RT lid before backfilling! Bolting
down the lid increases rigidity and helps prevent deformation.
Step 6a: Fill the AX-RT with 16 in. (410 mm) of water on both sides of the baffle.
Step 6b: Backfill around the unit with a 16-inch (410-mm) layer of material.
nKey Points:
• Do not use native material to backfill if it is primarily sand; very soft or
highly expansive clay; or if it contains debris, large (> 3/4-in. or 19-mm)
rocks, sharp rocks, peat, or muck. In these cases, use <_ 3/ inch (<_ 19
mm) rounded gravel, crushed stone, or pea gravel as fill material. This
material should be washed, free -flowing, and free of debris.
• Do not backfill with sand.
Step 6c: Compact the fill thoroughly with a mechanical compactor.
Step 6d: Fill the AX-RT with water to just above the midseam flange on both
sides of the baffle.
Step 6e: Add another 16-inch (410-mm) layer of backfill.
Step 6f: Compact the fill to 2-3 inches (50-75 mm) below the midseam flange.

See Orenco's PUCAccess Riser Installation (NIN-RLA-RR-1)
instructions for installing access risers on Orenco Tank Adapters.
Watertight seams are critical for proper performance.
Installation Steps
Step 7.• Install Adapters and Risers (If Needed)
Step 7a: Install tank adapters if needed. Follow the manufacturer's instructions.
• Use PRTA24 and PRTA30 Tank Adapter Installation (NIN-TA-PRTA-2)
instructions for installing Orenco PRTA24 or PRTA30 Tank Adapters.
• Use RRFTA and RRFTA30 Tank Adapter Installation (NIN-TA-RRFTA-1)
instructions for installing Orenco RRFTA or RRFTA30 Tank Adapters.
• Use FRTA30-FRP Tank Adapter Installation (NIN-TA-FRTA-1) instructions for
installing Orenco FRTA30-FRP Tank Adapters.
• Use Tank Adapter Installation for Roth Tanks (NIN-TA-RR-2) instructions for
installing Orenco FRTA24-R or PRTA30 Tank Adapters on Roth Fralo tanks.
Step 7b: Install the access risers and any necessary grommets.
• Use PVC Access Riser Installation (NIN-RLA-RR-1) instructions for installing
access risers on Orenco Tank Adapters and grommets in access risers.
nKey Points:
• Mode 3 systems require a 1-in. (25-mm) grommet in the tank's inlet riser.
The grommet must be on the same side of the riser as the AX-RT unit's
return line.
• The seam between the tank and the tank adapter has to be watertight.
• Watertight seams and penetrations are critical for proper performance.
• Before installing the riser, make sure the riser is the correct height — the
recommended riser height is 2-3 inches (50-75 mm) above final grade.
• Before installing the riser, make sure that the riser penetrations are made
at the correct height to make connections.
• Before installing the riser, make sure the penetrations are aligned correctly.
• After installing the riser, make sure all adhesive seams are smooth, con-
tinuous fillets, free of voids.
• After installing the riser, make sure the adhesive is set before continuing.
Step 8: Test Tank and Adapter Seams For Watertightness
Step 8a: Test the tank for watertightness if it has not been tested already.
Note: Follow the manufacturer's recommendations for watertight-
ness testing. Some manufacturers require the tank be fully backfilled
before testing watertightness.
Step 8b: Test the tank -to -riser adapter seams for watertightness.
• Use PVC Access Riser Installation (NIN-RLA-RR-1) instructions to test the
seams between the access riser, tank adapter, and tank for watertightness.
nKey Points:
• Watertight seams are critical for proper system performance — all tank -
to -riser seams must all pass the watertightness test before you continue.
• Follow all applicable regulations and manufacturer's instructions for water-
tightness testing.

Installation Steps
Step 9: Test AX-RT Midseam for Watertightness
Step 9a: Make sure the AX-RT unit is filled with water to 1-2 inches (25-
50 mm) above the midseam flange on both sides of the tank baffle.
Step 9b: Wait 15 minutes and then inspect the midseam flange for leaks.
There should be no drop in liquid level and no visible leakage from the seam.
Step 9c: If there is any leakage, contact your Dealer for information on
repairing the AX-RT unit.
Step 10. Install Effluent Filter
Install the effluent filter after the tank has been water tested.
Step 10a: Verify the model of the effluent filter.
• Orenco's FTSO444-36V, FTW0444-36V, and FT0822-14B filters are
the only models allowed for use with the AX-RT Treatment Unit.
Step 10b: Dry test -fit the effluent filter on the septic tank's outlet pipe.
n Key Points:
• Make sure the filter is plumb.
• Make sure the filter is snug to the tank wall with enough clearance for
easy removal of the filter cartridge.
Step 10c: Secure the filter to the outlet pipe with one of the following methods:
• Glue the filter onto the tank outlet pipe with primer and glue, or
• Secure the filter with a stainless steel set screw.
Step 1 Od: If necessary for ease of access, extend the cartridge handle
with a longer length of 3/-inch nominal (20-mm DN) Schedule 40 PVC pipe.
Step 11: Connect Transport Line from Tank to AX—RT
Step 11a: Dry fit the 4-inch (100-mm) transport line and any fittings
between the outlet of the septic tank and the inlet of the AX-RT unit.
QKey Point: Confirm there is a minimum fall of 1/8 inch per ft (10
mm per m or 1 %) from the septic tank's invert of outlet to the
AX-RT unit's invert of the inlet.
Step 11 b: Glue all of the transport line pieces in place.
OIMPORTANT Do not use primer on ABS parts.
Step 11c: For Mode 3 units, glue all of the return line pieces in place.
• Install the 1-in. (25-mm) return line between the return line port and
the 1-in. (25-mm) grommet for the return line on the tank's inlet riser.
• To avoid siphoning, the return line should allow effluent to pour into the
tank from the height of the riser grommet.
Fill AX-RT unit with water to 1-2 inches (25-50-mm) above
the midseam flange on both sides of the baffle.
Effluent filter installed on the septic tank outlet.
1/8 inch minimum fall
Confirm a minimum fall of 1/8 inch per foot (10 mm per
meter or 1 %) from the septic tank's invert of outlet to
the AX-RT unit's invert of the inlet.

Passive air vent
Install the vent within 20 ft (6 m) of the AX-RT unit
Wire control panel.
Installation Steps
Step 12. Connect Passive Air Vent
Use 2-inch (50 mm) PVC pipe to plumb the passive air vent to the 2-inch
(50 mm) vent fitting that protrudes from the outlet side of the AX-RT unit.
nKey Points:
• Install the vent within 20 ft (6 m) of the AX-RT unit, preferably near a
wall or other location that will protect it from damage.
• Make sure the vent line is sloped back a minimum of inch per foot
(20 mm per meter) so that it can drain back into the unit.
• Make sure there are no "bellies" in the line that can collect water.
• Make sure the vent's top is a minimum of 3 in. (75 mm) above final grade.
Notes:
• The air vent can easily be hidden by shrubbery or landscaping.
• The air vent can be painted to better blend in with landscaping.
Step 13. Connect AX-RT Outlet to Transport Line

Step 14: Mount Control Panel and Perform Wiring, Cont.
Step 14c: Route wires and connect the panel, pump, float switches, and other
equipment shown in the instructions and schematics into the control panel.
OIMPORTANT Follow all applicable regulations and electric codes.
QKey Points:
• Use watertight wire connectors to avoid electrical shorts and other issues.
• Be sure to seal the conduit at the control panel and at the splice box
with UL-listed sealing foam, putty, or silicone sealant.
Note: To help identify wiring runs for individual pumps and float
switches, use different -colored wires for each electrical component.
Step 15. Perform AX-RT Operational Test
OIMPORTANT Before using a generator to operate a pump, contact
your Dealer or Orenco to make sure it can supply sufficient starting
amperage to the pump.
Step 15a: Rotate the manifold so that the spin nozzles face upward.
Step 15b: Remove the cap at the end of the manifold.
Step 15c: Toggle the recirc pump "AUTO/OFF/MAN" switch to "MAN" for
10-20 seconds to flush any debris out of the manifold.
IMPORTANT Always make sure there is enough water in the
AX-RT's recirc/blend chamber to safely run the pump.
Step 15d: Rotate the manifold so that the spin nozzle faces down and
reinstall the cap on the end of the manifold.
Step 15e: Install the pressure gauge on the manifold.
Step 15f: Toggle the recirc pump "AUTO/OFF/MAN" switch to "MAN" and adjust
the gate valve for a pressure gauge reading of 3.0-3.5 psi (20.7-24.1 kPa).
Note: If the manifold won't pressurize to 3.0-3.5 psi (20.7-24.1 kPa),
check for debris, line breaks, or broken valves, and verify that the pump has
sufficient power. Contact your Dealer for additional assistance.
Key Point: Check for complete spray coverage of the textile media and
adjust the pressure as needed for complete coverage.
Step 15g: Toggle the recirc pump "AUTO/OFF/MAN" switch to "OFF"
Step 15h: Remove the pressure gauge.
Step 15i: Return the recirc pump "AUTO/OFF/MAN" switch to "AUTO."
Rotate the manifold so spin nozzles face upward.
Remove the cap at the end of the manifold.

Installation Steps
Step 15. Perform AX-RT Operational Test, cont,
Step 15j: If the system uses a VCOM­ control panel, use the instructions that
came with it to place the control panel in "Test Mode." If the system uses an
MVP control panel, go on to the next step.
Step 15k: Check the operation of the recirc chamber's float switches by
raising and lowering the low-level, mid -level, and high-level float in turn and
verifying that each performs its intended function.
• If the AX-RT unit has a discharge pump, continue to step 151.
• If the AX-RT unit has an MVP panel and gravity discharge, go to step 15o.
• If the AX-RT has a VCOM panel and gravity discharge, take the panel
out of "Test Mode" and go to step 15o.
OIMPORTANT Always make sure there is enough water in the
AX-RT's discharge chamber to safely run the pump.
Step 151: Toggle the discharge pump's "AUTO/OFF/MAN" switch to "MAN"
and verify the pump runs.
Step 15m: Toggle the discharge pump's "AUTO/OFF/MAN" switch to "AUTO."
Step 15n: Check the operation of the discharge chamber's float switches by
raising and lowering the low-level, mid -level, and high-level float in turn and
verifying that each performs its intended function.
• For units with a VCOM control panel, take the control panel out of "Test
Mode."
Step 15o: Make sure the recirc pump and (if equipped) discharge pump's
"AUTO/OFF/MAN" switches are toggled to "AUTO."
Step 15p: Close and bolt down the lid on the AX-RT unit.

Installation Steps
Step 16. Complete Backfilling
nKey Points.
• When backfilling, be careful not to alter the slope of any of the pipes.
Brace the pipes or place the pipes on a compacted bed and carefully
fill around them.
• Before backfilling, make sure the AX-RT unit's lid and all riser lids are
bolted down.
Step 16a: Backfill the septic tank excavation if it has not yet been done.
Follow the tank manufacturer's guidelines for backfilling.
Stepl6b: Backfill and compact around the AX-RT unit in maximum 12-inch
(305-mm) lifts.
n
Key Points.
• Do not use native material to backfill if it is primarily sand; very soft or
highly expansive clay; or if it contains debris, large (> 3/4-in. or 19-mm)
rocks, sharp rocks, peat, or muck. In these cases, use <_ 3/4-in. (<_ 19
mm) rounded gravel, crushed stone, or pea gravel as fill material. This
material should be washed, free -flowing, and free of debris.
• For installations in non -cohesive soils* with high seasonal water tables,
use 3/-inch crushed rock as the backfill material.
• Do not backfill with sand.
Step 16c: Compact the fill thoroughly with a mechanical compactor.
AKey Points.
• The bottom of the AX-RT lid should sit 2 inches (50 mm) above final
grade.
• After backfilling, call the system's Service Provider to arrange for the
official System Start-up.
Step 16d: Be sure the AX-RT unit's lid is closed and secured.
Step 16e: Be sure the septic tank's access lids are secured.
'As described in OSHA Standards (29 CFR, Part 1926, Subpart P, Appendix A), noncohesive soils
or granular soils include gravel, sand, or silt with little or no clay content. Granular soil cannot be
molded when moist and crumbles easily when dry. Cohesive soils include clayey silt, sandy clay,
silty clay, clay, and organic clay. Cohesive soil does not crumble, can be excavated with vertical
sideslopes, is hard to break up when dry, and when moist, can be rolled into threads without
crumbling. For example, if at least a 2-inch (51-mm) length of 1/8-inch (3-mm) thread can be
held on one end without tearing, the soil is cohesive.
2 in. (50 mm)
above final grade
Maintain minimum 1/8 in.
(10 mm or 1%) slope
Backfill the AX-RT in 12-inch (300 mm) lifts.

Using a Pump Curve
A pump curve helps you determine the best pump for your system. Pump curves show the relationship between flow and pressure (total dynamic
head, or TDH), providing a graphical representation of a pump's optimal performance range. Pumps perform best at their nominal flow rate. These
graphs show optimal pump operation ranges with a solid line and show flow rates outside of these ranges with a dashed line. For the most accurate
pump specification, use Orenco's PumpSelect- software.

VeriCornrnO AX20B Control Panels
Applications
VeriComm° AX20B remote telemetry control panels are used in
AdvanTex° AX20 Treatment Systems with two pumps for timed recir-
culation and pump discharge. Coupled with the web -based VeriComm
Monitoring System, these affordable control panels give the ability to
remotely monitor and control treatment system operation, with real-
time efficiency to wastewater system operators and maintenance
organizations, while remaining invisible to the homeowner. AX20B
panels allow remote operators to change system parameters, includ-
ing timer settings, from the web interface. Interlocked controls prevent
recirculation pump operation if there is a high-level alarm on the dis-
charge side.
Standard Models: VCOMAX20B1, VCOMAX2OB2
Features, cont.
Advanced Control Logic
• Activates system diagnostics in the event of a float failure or malfunc-
tion and maintains normal system operation until servicing can occur
Communication and Alarm Management
• Provides remote telemetry and a web -based monitoring applica-
tion for communication and alarm management (see VeriComm
Monitoring System, NTD-CP-VCOM-1)
• Updates point values (including timer settings) and queued changes
during each host communication session
• Contacts with host monthly; more frequently during alarm conditions
Multiple Communication Methods
• Call -In to VeriComm° Host (phone line or optional high speed internet)
— Signals critical fault conditions that require immediate attention
(e.g., pump failure) through automatic alarm notifications
— Signals less -critical fault conditions (e.g., stuck float switch) through
automatic alert notifications and triggers the panel's troubleshooting
logic and alternative operating mode
— Sends updates through automatic update notifications, including
alarm updates or all -clear notifications following alarms/alerts, as
well as normally scheduled monthly panel reports
—Allows manual, forced communication from panel to host for updat-
ing point values and receipt of queued changes
• Real -Time, Manual Direct Panel Connection
—Allows a local operator real-time access to detailed logged data
and the ability to change point values through direct connection via
RS-232 serial port from a laptop or Android° device with optional
Bluetooth° kit
LeriComm AX20B1 SA UV IB PT RG —Allows a local operator to initiate an auto -answer mode in real-time
Features Upgrade Kit is required if Internet line is used) to access detailed logged data and the ability to change point val-
ues via direct, forced communication at the site
Three Operating Modes
• "Start -Up Mode" collects trend data and establishes operating stan-
dards during the first 30 days of operation
• "Normal Mode" manages day-to-day functions
• "Test Mode" suspends data collection and alarm reporting during
installation and service
Data Collection and Utilization
• Compiles data logs of system conditions and events such as pump
run times, pump cycles, and alarm conditions
Troubleshooting and Diagnostic Logic
• Reports suspected component failures, which then trigger alarms
Open -architecture software with password security is used during
real-time, manual connections. Orenco offers BT-VCOM software as an
option, but VeriComm panels require no proprietary software.VT100
protocol allows access and control from a Mac or PC computer using a
simple communication program (e.g., Windows° HyperTerminal), with
multilevel password protection ensuring that only qualified personnel can
access the panel's data.
Status Light Indicators
— Flashing green LED for normal operation
—Yellow LEDs for status of digital inputs
— Red LEDs for status of digital outputs and modem activity
UL-recognized and FCC -approved

The float switch assembly is typically mounted in the screened pump vault or effluent screen inside of a septic or dosing tank.
The assembly is detachable without removal of the screened pump vault or effluent screen. A typical float switch assembly is
shown below.
Each float cable is provided with a color marker. This marker indicates the
function of the float. Make sure that your float cable color markers corre-
spond with the wiring diagram provided. If the wiring diagram does not
match your float cable marker colors, contact Orenco Systems® Inc. or
your local dealer for assistance.
To check for proper float switch operation, move each switch up and down
and check for interference. Remove the assembly from its holding bracket
by snapping it out of the holding bracket.

If any float interferes with another, the float may be adjusted by loosening
the stainless steel set screw provided in the float collar. Using a phillips
screwdriver, slowly back the screw out of the collar to a point at which the
collar may be adjusted. Be careful not to back the screw completely out of
the collar. Carefully rotate the collar on the stem until the float switches can
move freely past one another. Tighten the stainless steel set screw and
recheck.
Warning: Be careful not to alter the the tether lengths of any of the floats.
Alteration of the tether length may affect proper operation of the float
switch assembly.
Check the float settings with the project plans and specifications. If the set-
tings need to be adjusted, loosen the set screw as described in step 3.
Adjust the float switches to the desired level and tighten the set screw.
Make sure float level settings do not violate any state or local regulations.
Note: The float stem provided is the maximum length possible without
interfering with the pump minimum liquid level or screened pump vault
intake ports. Never lengthen the float stem without prior approval from
Orenco. Lengthening of the float stem will void the warranty.
Replace the float switch assembly in the holding bracket. Make sure the
assembly snaps fully into the bracket.
To allow for easy removal of a float switch assembly, a 1" diameter handle
may be added to the top of the float switch assembly. Measure the distance
from the top of the float switch assembly up to about one foot from grade
level. Cut a 1" diameter PVC pipe to the measured length and glue it into the
handle.

Installation Instructions (continued)
When used with an Orenco electrical splice box:
Push the level control wires through the watertight cord grips into the
electrical splice box. Leave an adequate length of electrical cable coiled
inside the riser to allow for easy removal of the pump and float switch
assembly. Do not remove the colored markers or the paper tags from the
float cables, and do not try to thread the markers and tag through the
cord grip. Tighten the cord grips by hand, not by tool, then test the tight-
ness of the cord grips by tugging on each cable. A cable is secure when
the cord grip is tight enough to prevent slippage. Adequate lengths of
cable should be left within the splice box to allow easy removal for future
disconnecting and resplicing.
Note: See the splice box instructions (EIN-SB-SB-1) and
corresponding splice box diagram for connection instructions.

During the annual inspection, follow the testing procedures provided to ensure that the system is operating properly. If a float is
found to be faulty, either during the annual inspection or during troubleshooting after an alarm condition, see the section below
titled Removing and Replacing Inoperative Floats.
Removing and Replacing Inoperative Floats
Important Before doing any work either on the wiring to the level control floats and pump in the vault or in the pump control
panel, switch the circuit breakers in the panel to their "OFF" positions, then switch off the power to the system at the service
entrance panel.
1. Remove the float assembly from the vault.
2. Using a Phillips screwdriver, remove the stainless steel screws from the splice box lid, being careful not to drop the screws
into the tank. If the splice box was submerged, or if there is a crack in the conduit, there may be water in the splice box. If
this is the case, remove water from the splice box with a syringe, sponge, or other appropriate method. Loosen the cord grip
at the splice box and verify the appropriate splice for the float. Unscrew the wire nuts and remove the float.
3. Remove the inoperative float and replace it with a new one. Push the float cable through the watertight cord grip into the
electrical splice box. Leave an adequate length of electrical cord coiled inside the riser to allow for easy removal of the float
assembly. Do not remove the colored markers or the paper tags from the float cords, and do not try to thread the markers and
tag through the cord grip. Tighten the cord grip by hand, not by tool, then test the tightness of the cord grip by tugging on the
cord. A cord is secure when the cord grip is tight enough to prevent slippage. An adequate length of cord should be left
within the splice box to allow for easy removal for future disconnecting and resplicing.
4. Refer to document EIN-SB-SB-1 for instructions to splice the float wire to the wire from the control panel. Attach the float
wires using the waterproof wire nuts. It is necessary to replace this wire nut with a new watertight wire nut. Always use
watertight wire nuts or heat shrink splice kits for all connections!
5. Replace the float and collar and return the assembly to the pump vault.
6. Reconnect power and test the unit.

Notes
State: normally open or normally closed
The default state of a float normally open or normally closed refers to the contact
positions in the float when the float is resting (down). Float switches have an internal contact.
The terms "normally open" (N/O) and "normally closed" (N/C) refer to the state of the float
switch contact in the down position. A normally open float switch has an open contact (off) in
the down position and a normally closed float switch has a closed contact (on) in the down
position. Different panel functions require different types of float switches. Most applications
require float switches that are normally open. One notable exception is the redundant off and
low-level alarm function that requires a normally closed float switch, except with MVP and
VCOM panels.
2IR (intrinsically safe relay)
Approved for use with intrinsically safe, Class 1, Division 1 applications, where reliable float
switch operation with very low current is required.
Drawdown
Drawdown (in inches) refers to the difference in liquid level between a float switch's activation
and deactivation points. Drawdown can be altered by adjusting the tether length of the float
switch cord. When selecting float switches, keep in mind thatany float switch that can directly
start and stop a pump (one that has no motor contactor in the control panel) should have a
drawdown capability, to avoid rapid cycling of the pump.
Signal -rated or motor -rated
Every float has a maximum amount of current it can handle. Exceeding these limits may cause
premature failure. Signal -rated or "control" floats are used to activate pump control panels
and alarms. Only low amperage signals pass through these float switches, hence the float
switch is "signal -rated. "All Orenco panels that use motor contactors can use signal -rated float
switches. In some systems, a float switch is used to directly start and stop a pump. In this
application, the current that is running the pump passes through the float switch as well, and
the float switch most be "motor -rated. "In most instances, a motor rated float switch can be
used as a signal float switch.

The Irrigation Innovators
here's nothing more embarrassing —or more
wasteful or costly —than an irrigation system
that runs when it doesn't have to... in the rain.
Mini-Clik° provides the simplest, most effective way
to prevent sprinklers from coming on during or after
precipitation. It easily installs on any automatic irrigation
system, then shuts sprinklers off in a storm and keeps
them off, automatically compensating for the amount
of rainfall that occurred. Disks absorb water and expand
proportionally to the amount of rain that fell (e.g., a
small cloudburst would result in little absorption, a
6" thunderstorm would lead to more absorption and
expansion). As the moisture -laden disks expand, they
eventually activate a switch that interrupts the circuit from
the controller to the valves. Once dry, they contract and
release the switch. Thus, Mini-Clik o v F
automatically resets without ever R 'f•
affecting your controller. There's no WATER
better way to ensure that a system
isn't watering when it isn't necessary.

on the controller,
disconnect it. Attach one
wire of the Mini-Clik to the
"common" terminal
(usually marked "C") on
the controller. Attach the
other wire of the Mini-Clik
to the common wire
leading to the valves.
Note: The common wire
to the valves does not
have to be interrupted
at the controller. The
Mini-Clik may be wired
anywhere along the
common wire line.
B. 24 Volt Solenoid Valves

Figure 4)
Locate the common wire
to the solenoid valves and
the common wire leading
to the coil of the relay that
starts the pump. If these
two wires are connected
to the "common" terminal
on the controller,
disconnect both of them.
Twist together these two
wires along with one wire
from the Mini-Clik, and
secure with a wire nut.
Attach the other wire of
the Mini-Clik to the
"common" terminal on the
controller. Note: The pump
circuit output must be 24
Volts in this situation. Do
not proceed if 110V.
C. Special Instructions for
Mini-Clik-HV (See Figures
5 and 6)
The two taped and
stripped wires are the
ones to be used when
following these accompa-
nying diagrams. The third
wire should be terminated
with a wire nut (not sup-
plied). All wire connec-
tions with the Mini-Clik
should be made with wire
nuts and located in a
junction box.
Where the timer is
controlling a pump, the
relay may be inside the
timer, external or non-
existent. ff there is no
relay in the circuit, one
must be added. The
wiring for an internal or
external relay is the same:
the Mini-Clik breaks the
circuit to the coil of the
relay only. Either wire of
the coil may be broken.

Installation Instructions
depress the spindle at the top of the Mini-Clik until you hear the switch "click"
off. The sprinkler zone should stop instantaneously. If it does not, check wiring
for correctness. It is not necessary to "wet" test the Mini-Clik, although it will test
the operation fine, if desired.

Vent Ring Vent
The Mini-Clik can keep the irrigation system from
starting or continuing after rainfall quantities of 1/8",
1/4'', 1/2", 1/4" or 1 ". To adjust it to the desired shut-
off quantity, rotate the cap on the switch housing
so that the pins are located in the proper slots (see
Figure 7). Do not forcibly twist the cap as this might
break the pins.
The time that it takes the Mini-Clik to reset for
normal sprinkler operation after the rain has
stopped is determined by weather conditions (wind,
sunlight, humidity, etc.) These conditions will
determine how fast the hygroscopic discs dry out,
and since the turf is also experiencing the same
conditions, their respective drying rates will roughly parallel each other. So when
the turf needs more water, the Mini-Clik is already reset to allow the sprinkler
system to go at the next scheduled cycle.
There is an adjustment capability on the Mini-Clik that will slow down the reset
rate. By turning the "vent ring" (see Figure 7) to completely or partially cover the
ventilation holes, the hygroscopic discs will dry more slowly. This adjustment can
compensate for an "overly sunny' installation location, or peculiar soil conditions.
Experience will best determine the ideal vent setting.
The Hunter ICC and SRC controllers are equipped with a built-in bypass that
allows you to override an active sensor. For controllers not equipped with this
feature, should you desire to bypass the operation of the Mini-Clik for any reason
(i.e., turn on your system even though the Mini-Clik has shut "off" due to rainfall),
there are two simple ways to do this. The first is to add our Bypass Switch Box.
This mounts on or next to the controller, and by simply moving the switch, the
Mini-Clik is bypassed. The second method is to go to the Mini-Clik and raise the
"cap" a couple of settings higher or completely remove it. This takes the pressure
off the switch button, which allows the valve circuit to close again.
Note: Using the "manual"switch on non -Hunter controllers typically will not
bypass the sensor.
There is no required maintenance for the unit. The Mini-Clik does not have to be
removed or covered for "winterizing" purposes.
Troubleshooting
Follow these simple checks first before assuming the unit is bad and replacing it.
System will not come on at all:
A. First, check to see that the Mini-Clik discs are dry and the switch "clicks" on
and off freely by pressing the top of the spindle.
B. Next, look for breaks in the wire leading to the Mini-Clik and check all wire
junctions.
C. Finally, if the Mini-Clik is dry and the wire leading to it is good, check the Mini-
Clik switch by nicking the insulation of the two "outer" wires near the unit to
expose copper. Turn one sprinkler zone on, and apply a "jumper wire" across
the two exposed wires. If the sprinkler now comes on, the switch is bad. Wrap
all nicked wires with electrical tape.
System will not shut off even after heavy rainfall:
A. Check wiring for correctness (see "Operation Check to Verify Correct Wiring").
B. Check sensitivity setting on Mini-Clik — move cap to more sensitive setting.
The Mini-Clik is an accurate rain gauge and can be verified by setting up a
"tube" type rain gauge in the same vicinity and making periodic readings.
C. Is the rainfall actually hitting the Mini-Clik? Check for obstructions to rainfall
such as overhangs, trees or walls.
All Mini-Clik models are listed by Underwriters Laboratories, Inc. (UL). Samples of these devices have
been evaluated by ILL and meet the applicable ILL standards for safety.

Hinter®
In most installations, the Mini-Clik acts as a switch to break the circuit to the
solenoid valves of the irrigation system when it has rained. This allows the timer
to advance as scheduled, but keeps the valves from opening the water flow.
Once the Mini-Clik has dried sufficiently, the switch closes again to allow for
normal operation.
The Mini-Clik has three blue wires coming out of it. Two are connected to a 25
foot extension, and the third center one is left disconnected. This center blue
wire is the "normally open" lead of the switch and is not used in most installations.
The remaining two extension wires are colored (one "silver" tinned, the other
natural copper); however, in the following instructions it will not matter which
wire is connected at a given junction.
For the Model Mini-Clik-C: This rain sensor unit is the same as the standard
model except for the lack of an aluminum mounting bracket and the addition of
a'/2" threaded cap, which allows for the easy use of electrical conduit to totally
enclose the wires. Unless local code states otherwise, plumbing grade PVC pipe
can be used as well as electrical grade conduit.
For the Model Mini-Clik-HV: This rain sensor unit is designed to be used
with automatic irrigation systems of two principle designs: 1) single -station
electrical timer (e.g., Intermatic) that switches power to a pump, either directly
or through a relay; or 2) single -station electrical timer that switches power to a
solenoid valve.
Standard Model:
Using the screws
provided, mount the Mini-
Clik on any surface
where it will be exposed
to unobstructed rainfall,
but not in the path of
sprinkler spray. The
switch -housing portion
must be upright (as
pictured), but the swivel -
bracket can be moved for
mounting on any angled
surface. Loosen the
locknut and screw before
swiveling bracket, and
then re -tighten.
For the Conduit Model
Mini-Clik-C:
The conduit acts as the
mounting support for the
unit. Therefore, place
and mount the conduit
to allow for the desired
sensor location as
described in the main
instructions for the
standard model. Be sure
to support the conduit
sufficiently along its
various lengths.
For the High -Voltage
Model Mini-Clik-HV:
The mounting of this unit is primarily made by screwing the fitting end into the
threaded holes of covers to rectangular junction boxes (for outdoor use) or the
covers of round junction boxes commonly used for outdoor spotlights. Locate
the junction box so that with the Mini-Clik attached, unobstructed rainfall will hit
the outermost sensing end of the unit. If a longer reach is needed, the "Carlon"
flexible conduit piece can be substituted with a slightly longer piece (up to 8"
length with no support or up to 11" with support).
Helpful hints for mounting:
A. When looking for a suitable location such as on the side of a building or post,
the closer the Mini-Clik is to the controller, the shorter the wire run will be.
This will also minimize the chance for wire breaks.
B. The ideal location for mounting is not always the most practical location. In
the case where a compromise must exist (such as low location on a side wall
rather than the preferred high location), note that the Mini-Clik will still work
as it will always receive some rainfall — it just will not be as accurate in its
gauging as it could be.
Mini-Clik Rain Sensors
Installation Instructions
C. As described in the "Operation" section of this manual, 'reset rate" refers to
the amount of time it takes the Mini-Clik to dry out sufficiently for the sprinkler
system to be allowed to come back on. The mounting location will affect this
rate and should be taken into consideration should extreme conditions exist.
For example, mounting the Mini-Clik on a very sunny, southern end of a
building may cause the Mini-Clik to dry out sooner than desired. Similarly,
mounting on the northern end of a building with constant shade may keep the
Mini-Clik from drying soon enough.
Once the Mini-Clik is mounted, run the wire to the controller, and fasten it every
few feet with wire clips or stapled for best results. If an extension to the wire
provided is needed, use the following table to determine the minimum wire
gauge needed:
If the extension needed is: 25-50 ft. 50-100 ft. 100 ft. or more
use: 20 AWG 18 AWG 16 AWG
Important. The Standard Model Mini-Clik is sold and designed for hook up to 24
Volt irrigation controllers only. For wiring to 110V or 220V irrigation controllers,
please consult your distributor or this factory. All wiring must conform to National
Electrical Code or applicable local codes.
For the Model Mini-Clik-C: WARNING! This unit is designed to be installed in
conjunction with 24VAC circuits only. Do not use with 110 or 220VAC circuits.
Forthe Model Mini-Clik-HV: WARNING! This unit must be installed by a qualified
electrician in accordance with National Electrical Code and applicable local
codes. The electrical rating of this device is 125-250VAC at 10.1 amps. Do not
let current pass through this
device that exceeds this
rating. Do not install directly
in line with any pump.
Wiring to the Hunter SRC
The Mini-Clik connects
directly to the SRC. This
allows you to easily override
the sensor by using the RUN
(BYPASS SENSOR) position
on the dial.
1. Route the wires from the
Mini-Clik up through the
same opening used for
valve wiring.
2. Connect one wire to the
RS terminal and other
to the C terminal (See
Figure 1).
3. Connect the valve common
to the RS terminal.
Wiring to the Hunter ICC

BIOLINE DRIP TUBING
The worlds most advanced continuous
self deaning pressure -compensating
dripperline for wastewater.
Applications
• Can be used with domestic septic tank effluent
of 2201220 (ppm) BODITSS with proper design,
filtration and operation
• Typically Installed following a treatment
process
• Reuse applications including municipally
treated effluent designated for Irrigation
Eeaturesl eneflts
• Pressure Compensation - all drippers deliver
equal flow, even on sloped or rolling terrain.
• Unique Flow Path-Turbonet technology
provides more control of water and a high
resistance to clogging.
• Continuous Self -Flushing Dripper Design -
flushes debris, as it is detected - throughout
operation, not just at the beginning or end of
a cycle. Ensures uninterrupted dripper
operation.
• Single Hole Dripper Outlet from Tubing:
Better protection against root intrusion
Allows the dripperline to be used in
subsurface applications without need for
chemical protection
• ❑rippers Capture Water Flow From the Center
of the Tubing - ensures that only the cleanest
flow enters the dripper.
• Built -In Physical Root Barrier - drippers are
protected from root intrusion without the
need for chemical protection. Water exits
dripper in one location while exiting the
Tubing in another_
• Three Dripper Flow Rates - provides the
broadest range of flow rates available. Allows
the designer to match the dripperline to any
soil or slope condition.
• Bioline Tubing is Completely Wrapped in
Purple - the complete tubing is purple,easily
identifiying it as a non -potable, regardless of
how the tubing is installed.
• Vinyzene-Impregnated Drippers - prevents
buildup of microbial slime.
• Can be used subsurface - Bioline can be
installed on -surface, under cover or subsurface.
• No Special Storage Requirements - does not
degrade if stored outdoors.
• Techfilter Compatible an optional level of
protection, provides a limited lifetime
warranty against root intrusion.

Technka� Specs (Confd))
Register Unit - Registration available in U.S. gallons, cubic
feet or cubic meters.
Test Circle - Large center sweep hand with one hundred
(100) clearly marked gradations on the periphery of the
dial face (available on Direct Read and DIALOG 3G
registers).
Design/Operation - Velocity -type flow measurement.
Water that is evenly distributed by multiple converging
inlet ports flows past an impeller in the measuring
chamber, creating an impeller velocity directly
proportional to water flow rate. The meter's register
integrates that velocity into totalized flow.
An inherent advantage for this design is unparalleled
wear mitigation leading to sustained revenues.
The register assembly is removable under line pressure
permitting seamless, simplified upgrades in
reading technology.
Strainer - A rugged, 360-degree advance polymer
basket strainer protects the critical measuring
element from damage. The unique strainer design
smoothes the flow of water entering into the meter
creating a laminar flow that is gentle on the meter's
internal components. Tough materials operating in a
smooth, balanced environment enable the meters
to perform more accurately over time. Utilities'
investments last longer while capturing more revenue.
Measuring Chamber- The measuring chamber housing
and measurement element are built with an advanced
synthetic polymer. Measurement surfaces are not
wear surfaces, providing sustained accuracy despite
the presence of entrained solids in the water. A long
life, synthetic sapphire bearing serves as a wear
surface with radially balanced water flows. The
chamber housing is constructed in two parts to
allow access to the impeller. Bottom plates available in
Bronze, Cast Iron (CI) or Engineered Plastic.

Description
The Vortex filters are placed between the pump and dripfield
to screen out any debris. Spin plates at the top of each screen
direct the flow of debris to the base of the screen for easy
self cleaning.
Features
- Simple self cleaning filter. Geoflows Vortex filter
depends on a simple forward flush to self clean.
Incoming water is forced through a directional nozzle
plate onto the inside of the stainless steel screen. A
centrifugal motion starts inside the screen chamber,
throwing particles outward against the screen. Gravity
moves the debris down the screen wall to the flush
outlet at the base of the Vortex Filter.
- It is simple to install and operate, requiring very few
moving parts.
- Can be plumbed to self clean periodically
with electronically activated solenoid valves
(recommended), or continuously with slightly
opened ball valves.
- Sturdy stainless steel screen proven effective in onsite
wastewater applications. A sinteringprocess in which
three pieces of stainless steel mesh are transformed
into one; a perforated plate, 30m then 150 mesh.
- Body is a two-piece threaded housing with O-ring seal.
Molded from high heat ABS and chemical resistant
glass reinforced plastic.

Basic System Operating Instructions
for
Single Family Residence Drip
Wastewater Treatment Systems
These operating instructions are intended as general guidelines and should not be
interpreted as a complete and detailed explanation of how to operate this irrigation
system. Please note that these instructions are intended as a supplement to the permit
issued by the N.C. Department of Environment and Natural Resources Non -Discharge
Permitting Unit. As a result, any requirements or items noted in the permit document
supercede any recommendations noted in these instructions.
If you are unsure of how to operate the system, please contact a licensed contractor or
professional who can assist you with the operation of your system. Record the name and
contact information of an individual familiar with the operation of this system, along with
an emergency contact in the event immediate assistance is necessary.
CONTRACTOR CONTACT INFO.:

General Maintenance Considerations
This wastewater irrigation system has been designed to operate with minimum
maintenance and oversight after the initial system start-up period. However, routine
inspections are necessary and periodic maintenance WILL BE REQUIRED both by your
permit and for successful operation of the system.
No heavy vehicles or equipment should be driven over the treatment units,
tank areas, or irrigation field.
SEPTIC TANK:
The septic tank in this system operates exactly as a septic tank associated with a
conventional septic drainfield system. The purpose of the septic tank is to remove
particles and solids from the waste stream As a result, solids build up in the bottom of
the tank (just like a typical septic tank). Over time the solids will need to be removed
from the tank or clogging of the sand filter or pipelines may occur. In general, it is
recommended that solids be pumped from the septic tank every 3 — 5 years (depending on
how intense the usage). Private septic tank pumping contractors can do this and are
typically easily found in the white or yellow pages of the phone book.
Maintenance Schedule:
The effluent filter in the septic tank (attached to the outflow pipe) should be cleaned at
least every 6 months or per manufacturer's recommendations, whichever is more frequent
(see the manufacturer's guide on how to do this) and the tank solids should be checked
annually.
A contractor or septic system professional can clean the septic tank filter for you;
however, this task can be performed relatively easily and requires no special knowledge.
Remove the septic tank lid and remove the effluent filter (typically the filters are threaded
or snap into place). Be sure to use plastic gloves to avoid contact with the wastewater
since it could contain harmful bacteria or viruses. To clean the filter, use a garden hose
with a nozzle and spray off any debris from the filter back into the inlet side of the septic
tank. Once the filter is clean, place it back in the septic tank. Discard or disinfect the
plastic gloves using a mild bleach solution (1/2 cup Clorox or equivalent to 1-gallon
water). Replace the septic tank lid.
ADVANTEX FILTER:
The treatment component of the system is an AdvanTex media filter. Liquid from the
septic tank will flow into the pod and periodically be pumped across the filter fabric.
Wastewater will be treated in the pod and periodically be discharged. To prevent
groundwater from affecting the pod, the pod will be installed on a bed of gravel with a
concrete collar.
2
178

Effluent from the system should be sampled per the requirements of the system permit. If
no parameters are listed, AWT recommends sampling for the following parameters; Total
Suspended Solids (TSS), Biological Oxygen Demand (BODA Total Nitrogen (TN),
Ammonia -Nitrogen (NH3-N), and Fecal Coliform. If desired AWT can assist you in
collecting these samples (919-859-0669) and interpretation the results.
Maintenance Schedule:
Maintenance of this system will be conducted by a certified operator under contract with
the homeowner.
DISINFECTION — UV:
Disinfection for the system will be accomplished using a UV system. The UV light
should operate for at least one year prior to needing to be replaced. If the UV light burns
out an alarm will notify the operator. Also, the alarm light on the control panel will
illuminate. When the UV alarm is activated, the system will shut off the recirculation
pump and the system will cease to operate until the UV bulb is replaced.
Maintenance Schedule:
The UV component shall be checked weekly to ensure the alarm bulb (on control panel)
is not illuminated. The UV bulb should be cleaned on a 6-month interval. To clean the
bulb, the power to the system (UV bulb and pumps) should be turned off in the control
panel. The UV housing can then be removed using the attached handle. Once the UV
housing is clear of the riser, the quartz sleeve and bulb assembly can be removed from
the housing. While holding the base of the assembly, the quartz sleeve shall be wiped
with a clean paper towel. If scaling on the sleeve is noticed, a liquid cleaner such as CLR
can be utilized. The sleeve and bulb assembly shall be re -installed after cleaning. The
UV bulb should last in excess of one year but will be replaced as needed. It is
recommended that the homeowner (or contracted operator) maintain a back-up UV bulb
and quartz sleeve when it is time to replace the bulb. This service will be completed by
the engaged certified operator.
PUMPING SYSTEM, RAIN SENSOR & ALARMS:
The pump used for this system is a submersible pump that turns off and on based on
switches inside the pump tank. These switches toggle the pump timer on and off
depending on the effluent level inside the tank. The switches are designed such that the
pump will turn on, run for a set period of time, then shut off under normal operating
circumstances. When it has been raining, a rain sensor overrides this normal operation so
that effluent is not applied when the soil is saturated. Therefore, effluent is allowed to
build-up in the pump tank until it is dry enough to apply again. After a rainfall event, you
may notice that the pump operates more frequently. This is normal and should be
expected.
The pump is also equipped with a HIGH WATER alarm that activates when the liquid
level in the pump tank is too high. If this should occur it is important to not use any
additional water (i.e. don't flush commodes, use the washer/dishwater, take showers, etc.)
3
179

until the liquid level is reduced. In extreme cases it may be necessary to contract a septic
tank pumping contractor to pump out excess liquid from the pump tank if long periods of
rain prevent land application of effluent.
The pump will wear over time and will likely need replacement every 5 — 7 years (again,
depending on usage). A licensed septic contractor should be contacted for maintenance
or replacement of the pump.
Maintenance Schedule:
The storage and pumping component shall be checked weekly to ensure the alarm bulb
(on control panel) is not illuminated. It is important to inspect the pump tank, and
components on an annual basis to ensure no solids are building up on the tank bottom, to
ensure that the pump control switches are placed properly, and to verify proper pumping
of the effluent. These activities will be handled by the engaged service provider.
SUPPLY LINE TO DRIPFIELD:
The location of the supply line should be walked weekly to ensure that a line breakage
has not occurred. The area in which the line is buried should be monitored for any wet
spots or locations of excessive vegetation growth as these occurrences may be an
indication of a line breakage. No permanent structure shall be erected over the locations
of the Supply and Return lines. No heavy vehicles or equipment should be driven over
the Supply and Return lines.
Maintenance Schedule:
Walk location of lines weekly.
DRIP FIELD:
The drip field should be inspected weekly to verify proper operation and to ensure
driplines have not become damaged. Clogged or worn drip tubing should be replaced or,
in the event of minimal obstruction, cleaned. No heavy vehicles or equipment should
be driven over the irrigation area.
Fill placed in the irrigation area shall be monitored for signs of required maintenance
throughout the life of the drip field. The crown shall be maintained on the dripfield such
that water is shed away from the surface of the dripfield. Any rills or gullies that form in
the dripfield shall be filled and smoothed to match the surrounding topography. Low
spots that form or areas where water is ponding shall be filled to provide adequate
drainage throughout the dripfield. Areas where significant settling has occurred may also
require additional fill to maintain the required 12" separation from the SHWT. Any
additional fill should be placed beneath the drip tubing, which will require the tubing to
be temporarily relocated until the fill activities are completed. Areas of fill should be
mounded with an additional 2" of fill to allow for settling. Any fill used shall meet the
characteristics defined in the approved design.
4
180

Vegetation (grass for this system) in the application area is critical to the operation of the
treatment system. The application area should be allowed to remain in a natural state;
however, the area should be kept free of fallen trees and invasive weeds. Any saplings or
stumps that re -grow should also be removed from the application area by hand and
without damaging the drip components. The turf should be cut occasionally to keep the
turf at a manageable height. Cutting should be performed using a trimmer, scythe, or
other method that will not damage the drip tubing. Wheeled or tracked equipment should
not be used. A soil sample should be collected from the drip field area to determine
appropriate rates of lime and fertilizer application.
It is important to maintain the fencing around the application field in order to ensure that
access to the area is restricted. This is necessary to minimize human contact with the
treated effluent and to ensure the vegetation remains healthy.
SYSTEM OPERATION & SETTINGS
It should be noted that a contractor or other qualified professional should be contacted if
you are uncomfortable or unfamiliar with operating this system or if system
troubleshooting is necessary. In general, the following system operating parameters
should be monitored:
Clean -outs
A clean -out is located on the system just before the septic tank. If liquid backs up into
the house or the septic tank, the drainline may be clogged or the septic tank may have too
many solids in it to allow adequate flow through. A qualified contractor should be
contacted to unclog any blockages via these clean -outs. A pumping contractor should be
used to empty solids from the septic tank.
Septic Tank Effluent Filter Cleaning
The effluent filter attached to the outlet pipe of the septic tank should be cleaned every 6-
months, or per manufacturer's recommendations, whichever is more frequent. A
contractor or septic system professional can do this for you; however, this task can be
performed relatively easily and requires no special knowledge. Remove the septic tank
lid and remove the effluent filter (typically the filters are threaded or snap into place). Be
sure to use plastic gloves to avoid contact with the wastewater since it could contain
harmful bacteria or viruses. Depending on the filter housing, you may need to prevent
flow from leaving the tank while the filter is removed. To clean the filter, use a garden
hose with a nozzle and spray off any debris from the filter. Once the filter is clean, place
it back in the septic tank. Disinfect the plastic gloves using a mild bleach solution (1/2
cup Clorox or equivalent to 1-gallon water). Replace the septic tank lid.
Pump ON/OFF and Emergency HIGH Level Switches
The pump switches are used to control the operation of the pump. This system is
designed such that the pump is on for designated intervals set forth in the design
specifications. The pump operation is a timed dosing setup. When there is sufficient
181

liquid in the tank, the pump will operate at a specific time for a designated interval. In
periods of high water (following a rain event), the pump may operate more frequently.
An emergency high level switch is located in the pump tank that triggers an audible and
visual alarm in the event the liquid level gets too high. In this situation, the following
steps should be taken:
• Stop use of all water in the residence (to stop flow into the pump tank),
• Verify that the system has electrical power.
• Contact a qualified contractor to inspect the system (if needed)
If it has rained recently the pump may not be operating because the rain sensor is
temporarily blocking the system from operating. If this is the case, then the pump will
resume operation once it is dry enough. If the pump tank is in danger of overflowing and
continued rainfall is expected, contact a septic tank pump contractor to remove a portion
of the liquid in the pump tank. The pump tank has been designed to accommodate
approximately 5 days of effluent storage under normal usage. As a result, prolonged
periods of rain may cause a back-up of effluent in the system since the rain sensor
prevents application of effluent onto the drip field.
In general, a contractor or licensed professional should be contacted under any
circumstances where you are uncomfortable in operating the system or troubleshooting a
problem More detailed information on the installation and maintenance of specific
components of this system can be found in the manufacturer's installation and
maintenance specifications attached as part of this package. If you have difficulty finding
this information, please contact the manufacturer of the component.

The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide
information about natural heritage resources for the project referenced above.
A query of the NCNHP database, based on the project area mapped with your request, indicates
that there are no records for rare species, important natural communities, natural areas, and/or
conservation/managed areas within the proposed project boundary, or within a one -mile radius of
the project boundary.
Please note that although there may be no documentation of natural heritage elements within or
near the project boundary, it does not imply or confirm their absence; the area may not have been
surveyed. The results of this query should not be substituted for field surveys where suitable habitat
exists. In the event that rare species are found within the project area, please contact the NCNHP so
that we may update our records.
Please also note that natural heritage element data are maintained for the purposes of conservation
planning, project review, and scientific research, and are not intended for use as the primary criteria
for regulatory decisions. Information provided by the NCNHP database may not be published
without prior written notification to the NCNHP, and the NCNHP must be credited as an information
source in these publications. Maps of NCNHP data may also not be redistributed without
permission.
If you have questions regarding the information provided in this letter or need additional assistance,
please contact Rodney A. Butler at rod ney.butler�ncdcr.gov or 919.707.8603.
Sincerely,
NC Natural Heritage Program
