Dear Mr. Bennett,
March 10, 2023
RECEIVED
March 10, 2023
NCDEQ/DWR/NPDES
Thank you for your email comments regarding the application for the Eskridge Property
WWTS (Certificate of Coverage No. NCG551795).
Below, please find a response to each of the questions/comments listed in your e-mail
dated February 15, 2023. To facilitate the review of this response, each point from the
comment email is included in bold. We appreciate your time and attention in assisting us
with the project.
Comment:
1. The application material indicates that the current non -discharge spray
system has a spray field on adjacent property and the spray field is not
transferable. We assume that this means the permittee wishes to sell the
property and the adjacent landowner does not want to transfer the easement
for use of the spray field to a new property owner. The Division considers
discharge permits as a last resort when no sewer or onsite non -discharge
alternatives are available. Can you please provide documentation that
verifies why the offsite spray field is not available for use with this system.
1

Response: The assumption stated above is correct. Due to the current family
situation, the applicant desires to sell the property. The transferability of
the off -site easement that covers the sprayfield is not transferable without
the consent of the Grantor of the easement or its successor in interest. The
following excerpt is from the NC General Warranty Deed detailing the
transfer of the easement. The full document is included as Attachment B
of the original application.
Grantor acknowledges the existence upon its remaining property of a waste water effluent
spray field Chat is connected to the Grantee's septic system. Grantor hereby grants to
Grantees a limited easement for the continued use and operation of the spray field, Which
easenenta shall run with the land and be binding upon Grantor and its successors and assigns;
provided, however, that Grantor, for itself and its successors and assigns, hereby reserves
the unconditional right to terminate this limited easement absolutely and completely by
giving a minimum of six months' written notice to Grantees by certified mail, return receipt
requested. Grantees' refusal to accept the certified mail shall not limit the effectiveness
of the notice. The easement herein granted is personal to Grantees and is not transferable
without the consent of Grantor or its successor is interest.
The applicant, Mr. Eskridge, has repeatedly attempted to contact the
current landowner (Changhoon Shin) to no avail. It is our understanding
that the landowner may live out of the country. The contact address
listed on the Durham County GIS website also does not appear to be
current. Multiple attempts have been made by mail and email.
Attachment A includes two of the email attempts made by Mr. Eskridge.
2. The submitted application information is for a 3-bedroom home with flow of
450 gallons per day. For Single Family Discharge systems under the
discharge program, we consider allowable flow at 120 gallons per day per
bedroom. The Division will therefore consider this application for a flow
limit of 360 gallons per day. The application for the NCG550000 permit
documents the 120 gallon per day limit per bedroom but the application
submitted had been modified to change the language to 150. In the future,
please leave the application information unchanged and note any requested
differences and include discussion information in an attached letter.
Response: We acknowledge that the allowable flow is 120 gallons per day per
bedroom equating to a flow limit for this application of 360 gallons per
day. This was adjusted as the original non -discharge surface spray was
permitted for 450 gallons per day. We apologize for the inconvenience. In
future requests, we will ensure to leave application information
unchanged.
3. The application material notes a current non -discharge permit from
September 2013. Permit WQ0002908 was reissued September 10, 2018.
Since the permittee is still operating under this permit at this time, please
assure that they have access to the most current permit. You can access the
permit at our Laserfiche site at:
https://edocs.deq.nc.gov/WaterResources/DocView.aspx?dbid=0&id=726460
ii

Response: Thank you for bringing this to our attention. We have ensured that Mr.
Eskridge has access to the most recent version of the permit.
4. There is no discussion about any setback issues for the site so we are
assuming that there is no need for any setback waivers for the site. Is this
correct?
Response: The existing treatment system was permitted under the NCDEQ SFR
Wastewater Irrigation System Permit WQ0002908. It was the assumption that the
location was previously approved for the existing permit and subsequential permit
renewals. The system is within 10' of the property (substantially less than the required
50' setback). However, we are not aware of any setback waivers completed at the time of
permitting and reissuance of the permit.
If this would pose an issue for issuance of the Certification or Coverage/Authorization to
Construct under the General Permit, it is possible to install a new system that would
maintain the required setbacks for the discharge permit. We have included updated plans
and specifications for the Discharge System in Attachment B if it is deemed that a new
system would be required. We respectfully ask that the updated plans be included with
the current application for coverage.
5. Is there any documentation available to show recent cleaning of the septic
tank and pump tank? If so, could you provide these for our records as well.
Response: We have spoken with Richard Broadwell of The Water Specialist. He has
provided maintenance to the existing wastewater system over the years at the property.
The most recent pumping of the septic tank was in 2021. However, he was not able to
provide any records for the pumping service.
6. The NCG550000 application indicates (#7) that the system has a dosing tank
and recirculating sand filter. In other narrative descriptions in the material
provided the system is described as a sand filter system but it isn't clear that
it is a recirculating system with a dosing tank. Could you please clarify this
also.
Response: Based on the size of the existing sand filter system and current guidelines, the
assumption was that this was a recirculating sand filter. However, upon inspecting the
dosing chamber, it was found to be a gravity single pass sand filter. Effluent from the
system was sampled and found to meet the discharge requirements.
As mentioned in the previous response, if this would pose an issue for issuance of the
Certification or Coverage/Authorization to Construct under the General Permit, it is
possible to install a new system if that is deemed necessary. We have included updated
plans and specifications for the Discharge System in Attachment B. We respectfully ask
that the updated plans be included with the current application for coverage.

Dear John,
I hope this finds you well. I understand from Valerie Olszyk that you are out of the country but available
by email so am reaching out regarding a situation that impacts us both.
In the process of marketing my property at 5312 Farrington Road, it has been noted by several
individuals that the current language in the easement agreement between us was not well constructed
by Jesup & Lamont's attorney and could be problematic in finalizing a future sale of either of our
properties.
I am advised that the simple way to resolve this issue is to make both the right for operation of my spray
field on your property and for the right for your access to the well on my property be transferable to the
new owner in the event of a sale of either property. If you agree, I can have a new easement agreement
drafted for our mutual review and acceptance. Or, if you would prefer to chat about this first then, of
course, I would be happy to do so.
You can reach me by either email or at my mobile number listed below.
I look forward to hearing from you soon.
All the best.

Narrative Description
of
Discharge Treatment System
The Discharge System that has been designed considers the following components:
- Septic Tank
- AdvanTex AX20-RT Treatment Pod
- UV Disinfection
- Discharge Outlet
- Control Panel
Due to the advanced technology in this system, a Certified Operator should be contracted to
maintain this system.
Septic Tank
A new 1,250-gallon septic tank will be installed for this system. The existing 1,000-gallon tank will
be abandoned in place. An Orenco 8" Biotube effluent filter will be installed in the outlet end of the
septic tank. 24" access risers will be installed on both the inlet and outlet ends of the septic tank.
All wastewater from the single-family residence, including greywater, will be routed into the septic
tank. Waste that exits the septic tank will flow via gravity into the AdvanTex AX20-RT Treatment
Pod.
AdvanTex AX20-RT Treatment Pod
The treatment component of the system is an AdvanTex AX20-RT treatment pod. The pod is an
integrated unit that combines recirculation, treatment, and discharge modules into a single, sealed
unit. Liquid from the septic tank will flow via gravity to the inlet of the treatment pod and into the
recirculation tank portion of the AX-RT unit. Liquid from the recirculation tank will be periodically
applied across the filter fabric. Wastewater will be sprayed over the textile sheets. The wastewater
percolates down through the textile sheets and is distributed between the recirculation chamber and
discharge chamber by means of the tank baffle. The treated wastewater then exits the AX-RT unit
via gravity to the discharge outlet after passing through the UV disinfection system within the AX-
RT unit.
The recirculation pump is controlled by a system of 3 floats that operate the recirculation pump in a
Timed Dose arrangement. Float I (lowest elevation) is a redundant off float. Float 2 is a Peak
Enable Float and Float 3 acts as a High Water Alarm. Under normal operation, the redundant off
float will be engaged thereby activating the timer in the control panel. At the pre-set interval, the
pump will engage and distribute effluent over the textile fabric ("on" cycle). Following this period,
the pump will turn off and rest for a designated time ("off' cycle)". During periods of high water in
the recirculation portion of the tank, the Peak Enable float will engage and reduce the pre-set "off'
time and thereby send increased flow across the fabric. If the water level in the recirculation tank
continues to rise, the High Water Alarm will activate.
3of61

To prevent groundwater from affecting the pod, the pod will be installed on a bed of gravel. Anti -
flotation measures or a concrete ring installed around the mid -flange will be installed to provide
extra ballast to prevent the flotation of the pod during high water table conditions.
UV Disinfection
Disinfection for the system will be accomplished using a UV system. The UV light should operate
for approximately one year prior to needing to be replaced. If the UV light burns out or loses
sufficient intensity (below a set threshold) an alarm will activate and disable the system pump. An
alarm light on the control panel will also illuminate. When the alarm is activated, the homeowner
should reduce water use (laundry, dishes, washing) until the system is operating properly.
Discharge Outlet
The system discharges into a culvert located on the property. Riprap will be placed at the discharge
location to provide aeration of the water as it is discharged and also as erosion protection.
Vegetation and debris should be kept clear of the discharge location. A grate will be installed on the
discharge pipe to prevent animals and rodents from entering the discharge pipe.
Control Panel
One control panel will be installed with this wastewater system. This panel will control operation of
the pumps and UV system. If desired, this panel can be connected to a land -based phone line that
will notify the operator of system operation.

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.

6. Riser Watertightness Testing.......................................................................... 6
7. Adhesive Selection and Quantities...................................................................... 7
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.

Instruction Set 3:
Riser Installation — PRTA24-2 Adapters
Step 1: Prep Adapter Channel and Riser
Step 1 a: Roughen the adapter channel and the bottom surfaces of the riser
with sandpaper.
Step 1 b: Use a clean cloth and acetone or alcohol to clean the channel and the
bottom surfaces of the riser.
• The channel must be clean and dry for a good fit and watertight joint.
• Let the acetone or alcohol dry completely.
Step 2: Apply Adhesive
Fill the channel with methacrylate adhesive.
• For adhesive recommendations, see Instruction Set 7.
Note: If you're using a methacrylate adhesive that's non -self -leveling, use
enough to fully fill the channel, with no voids in the adhesive.
Step 3: Install Riser
Step 3a: If the riser has penetrations, align the riser correctly.
Step 3b: Firmly press the bottom of the riser into the channel.
• Twist the riser back and forth slightly to fully seat it and to create a good bond.
• If the inside seam is not completely filled, add adhesive to form a complete
fillet.
Step X Use a tongue depressor, putty knife, or clean cloth to make a good
fillet over the inside seam.
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.

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 1 a: 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 1 b: 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.

External Splice Box
Applications
The Orenco° External Splice Box attaches outside the access riser of an
underground tank. It's engineered specifically for water and wastewater
treatment systems and is especially suited for use in locations prone to
high groundwater and other wet conditions. Its separate conduit hubs,
large volume, and optional dividers make it useful for maintaining isola-
tion of high- and low -voltage wires, where needed. It has four cord
grips, which accommodate power cords for floats and pumps of
0.170 - 0.470 inches (4.3 -11.9 mm) in diameter. Unused cord grips
can be plugged watertight with the supplied cord grip plugs. Each
External Splice Box includes a riser adapter designed to provide a water-
tight connection between the splice box and riser.
iL
The External Splice Box is molded PVC.
It has a UL Type 6P listing for prolonged submergence.
General
To specify the Orenco External Splice Box for your installation, require the
following:
• Watertightness for prolonged submergence per UL listing (Type 6P)
• Attachment external to access riser to allow inspection with no need
to open the riser lid
• Volume of 126 in.3 (2065 cm3) for easy wiring access and multiple
wiring configurations
• Bottom entry, so conduit or direct -bury cable always remains below
minimum burial depth
• UV -resistant rating for outdoor use
• Optional divider plates for isolating high- and low -voltage wires from
separate conduits or direct -bury cable
• Included riser adapter to eliminate the need for a grommet

Biotubee Effluent Filter Installation
Model FT08 and All Base Inlet Models
(U.S. Patent Nos. 5294635 / 4439323)
Before You Begin
Be sure the tank is empty before you attempt to perform this installation.
In existing tanks or in tanks with short outlet stubs, it may be necessary to extend
the tank outlet stub by using a coupling and a pipe section. A coupling may also be
needed to bush from 3034 PVC to the Schedule 40 outlet of the filter.
IMPORTANT Take proper precautions and wear personal protection equipment
(PPE) whenever working in an enclosed area, such as a septic tank.
Step 1: Dry Fit Vault
Step 1 a: Remove the Biotube° filter cartridge from the vault.
Step 1 b: Dry fit the vault's outlet to the tank outlet stub.
• Make sure there is enough clearance at the tank opening to remove the
Biotube filter cartridge for cleaning and tank pumping.
Step 1 c: Remove the vault from the tank outlet stub.
Step 2: Install Vault And Filter
Stainless steel self -drilling screws can be used in place of PVC cement in this step.
Step 2a: Apply PVC cement to the outside of the tank outlet stub and the inside
of the vault's outlet.
• Don't use PVC cement if you are using stainless steel screws.
Step 2b: Press the vault into position on the tank stub.
• Make sure the vault is straight and vertical, adjust it if necessary,
• Secure the vault with the stainless steel screws, if you are using this method.
Step 2c: Install the Biotube filter cartridge into the vault.
• Makes sure the handle tees snap into the vault body.
Step 3: Adjust Handle Length, If Necessary
If necessary, extend the filter cartridge's handle to make access easier from the
top of the riser.
• Use 1-in. (25-mm) Schedule 40 PVC for the handle extension.
• If the handle extension is longer than 4 feet (1.2 m), make a stiffening "ladder"
with tees and horizontal pipe sections.
• Secure the extension on the handle with stainless steel self -drilling screws or
PVC cement.

AdvanTexO AX-RT Treatment Systems
Applications
Orenco's AdvanTex AX-RT Treatment System is a single, complete,
self-contained module that treats septic tank effluent to better than
secondary standards with nitrogen reduction before discharging it by
means of pump or gravity. It is ideal for new home construction, and it
is also well suited for:
• Repairs and retrofits
• Small sites and poor soils
• Sites that require shallow bury
AX20RT 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,
treatment, 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.
The heart of the system is the AdvanTex Recirculating Treatment Tank,
a sturdy, watertight, corrosion -proof dicyclopentadiene (DCPD) tank
that includes the same dependable, textile treatment media found in
all AdvanTex products.
Not to be sold individually in the state of Georgia.

installation may void warranties.
OIMPORTANT The backwash discharge from a salt -type water softener MUST NOT be plumbed into an AX-RT Treatment Unit
or the preceding septic tank. Failure to follow this instruction, or any other in this manual, will void the system's warranty.
Contact yourAdvanTex Dealer if you have any questions about any household plumbing arrangements that may interfere with
the functioning of the system.
ter'' Note. All pipe diameters provided are U.S. nominal PVC pipe sizes. If you are using metric pipe, you may need adapters to
connect to the U.S, fittings supplied with AdvanTex Treatment Systems.
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.

This is a sample sketch of an AX-RT unit installed parallel
to the septic tank, with no antibuoyancy measures installed.
Distances and estimated fall from the septic tank's invert of
the outlet to the AX-RT unit's invert of the inlet are included.
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.
I Key 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 1 a: 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 1 b: 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:
QKey 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 1B 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.
QKey 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 < %2- to 3/-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 1B 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 unit's lid.
nKey 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), conL
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.
QKey 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/-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 PVCAccess 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.
n Key Points:
• Watertight seams are critical for proper system performance — all tank -
to -riser seams must all pass the watertightness test before you continue.

Installation Steps W=
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 I Oa: 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.
nKey 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 10d: If necessary for ease of access, extend the cartridge handle
with a longer length of 3/4-inch nominal (20-mm DN) Schedule 40 PVC pipe.
Step 11: Connect Transport Line from Tank to AX-RT
Step 11 a: 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.
Key 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 IIb: Glue all of the transport line pieces in place.
OIMPORTANT Do not use primer on ABS parts.
Step IIc: 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.

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.
n
Key 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 1/4 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
Glue the AX-RT discharge plumbing line to the transport line for final discharge.
Step 14. Mount Control Panel and Perform Wiring
n
Key Points:
• This step should be performed by a licensed or qualified electrician.

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 (provided) 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
IMPORTANT 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: Manually run the recirc pump and adjust the gate valve for
consistent coverage over the textile area and continual water distribution
against the splash guards on the edges of the textile.
Note: If the spin nozzles won't properly distribute with the gate valve fully open,
check for debris, line breaks or damaged valves. Check and verify the pump
has sufficient run voltage and is operating correctly. Contact your Dealer for
additional assistance.
Key Point: If using a pressure gauge for calibration, the residual pressure
in the manifold should be about 4psi. Check for complete spray coverage
over the textile media and adjust the gate valve as needed per Step 15e.
Step 15f: 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 16: Complete Backfilling
n
Key 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.
4!TS 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/a-in. or 19-mm)
rocks, sharp rocks, peat, or muck. In these cases, use <_ 3/-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.
n Key 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.

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 PumpSelecf" software.

VeriCornmO
AXA Control Panels
Applications
VeriComm° AXA1 and AXA2 remote telemetry control panels are
used with simplex pumping operations —timed recirculation,
with gravity discharge —for AdvanTex° Treatment Systems.
Coupled with the VeriComm Web -based Monitoring System,
these affordable control panels give water/wastewater system
operators and maintenance organizations the ability to monitor
and control each individual system's operation remotely, with
real-time efficiency, while remaining invisible to the homeowner.
VeriComm AXA panels allow remote operators to change system
parameters, including timer settings, from the Web interface.
Panel
To Specify...
To specify this panel for your installation, require the following
Basic Control Logic. Two Operating Modes
• A "Normal Mode" that manages day-to-day functions.
• A "Test Mode" that suspends data collection and alarm report-
ing during installation and service.
Data Collection and Utilization
• Data logs of system conditions and events, such as pump run
times, pump cycles, and alarm conditions.
Troubleshooting and Diagnostic Logic
• Troubleshooting capabilities that can report suspected failed
components, which then trigger Alarms.
Advanced Control Logic
• Advanced control logic that activates during float malfunctions
to diagnose the situation and keep the system operating nor-
mally until servicing.
Communication and Alarm Management
Remote telemetry capabilities coupled with a Web -based
monitoring application (see VeriComm Monitoring System,
ATD-WEB-VCOM-1)for communication and alarm manage-
ment. Updating of point values (including timer settings) and
receipt of queued changes during each communication ses-
sion with host. Communication sessions that occur monthly, at
a minimum, and more frequently during alarm conditions.
• Multiple methods of communication, as follows:
Call -In to VeriComm® Host
— Automatic notification to host of "Alarms," which signal
fault conditions that need to be addressed immediately
(e.g., pump failure).
— Automatic notification to host of "Alerts," which signal
less critical fault conditions and which trigger the panel's
troubleshooting logic and alternative operating mode
(e.g., stuck float switch).
— Automatic notification to host of "Updates," which include
alarm updates or all -clear notifications following Alarms/
Alerts, as well as normally scheduled monthly panel reports.
— Manual, forced communication from panel to host to effect
an updating of point values and receipt of queued changes.
Real -Time Direct Connection to Panel
— Manual, direct connection at the site via RS-232 serial port,
to allow a local operator real-time access to detailed logged
data and the ability to change point values from a laptop.
— Manual, forced communication by local operator/hom-
eowner at the site to initiate an auto -answer mode, allowing
a remote operator real-time access to detailed logged data
and the ability to change point values.
During real-time, manual connections, software with open
architecture (and password security) is used; no proprietary
software is required. VT100 protocol allows access and control
from any computer modem (Mac or PC) with a simple com-
munication program (e.g., Windows° HyperTerminal); multilevel
password protection in panel ensures that only qualified per-
sonnel can access the panel's data.
Additional Features

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/0) 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 that any 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 must be "motor -rated. " In most instances, a motor -rated float switch can be
used as a signal float switch.

Float Switch Assembly
Installation Instructions
These instructions cover the installation of a float switch assembly. To set
and adjust float switches, see NIN-MF-DA-1, Float Switches: Settings and
Adjustments, or NIN-ATX-DA-1, Float Switch and RSV Settings: Instructions for
Residential AdvanTex Systems. For wiring instructions, see the schematics and
wiring diagrams included with the control panel for the float switch assembly.
Step 1: Prep the Float Switch Assembly
Step 1 a: Check for vertical and horizontal clearance between the float
switches.
• Move each float through its range of vertical and horizontal motion.
• The float switches shouldn't interfere with one another during this check.
Step 1 b: If the switches interfere with one another, loosen the set screw on
one switch's collar and adjust the collar horizontally until the switch is clear of
the switch(es) above or below it.
• Don't back the set screw completely out of the float collar.
Step 2: Install the Float Switch Assembly
Once any adjustments are made, install the float switch assembly.
IMPORTANT
• DON'T lengthen the float stem without prior approval from Orenco.
• DON'T change the float tether lengths. Changing the tether lengths may
disrupt proper operation of the assembly.
Step 2a: Lower the assembly into position.
• As you lower the assembly, check that the float switches don't interfere with
walls or components in the tank, pump vault, or flow inducer.
• If the float switches interfere with walls or components, remove the assembly
and adjust the float(s) horizontally for clearance.
Step 2b: Attach the float switch assembly to the assembly into the float bracket.
• Align the top of the assembly with the top of the float bracket.
• The float bracket is usually fixed to the Biotube® effluent filter, the flow inducer,
or the side of the pump basin.
Step 2c: Secure the loose cables to the splice box by looping them over the internal
splice box or secure them with the external splice box's hook -and loop strip.
Step 2d: Install a handle extension if the float switch assembly's handle isn't within
easy reach for removal and servicing.
• Measure from the top of the float bracket to 6 inches (150 mm) below the top
of the riser.
• Mark and cut a section of 1-inch (25-mm) PVC pipe to the measured length.
• Remove the float switch assembly from the float bracket and glue the pipe
section into the tee fitting.
• Wait for the glue to dry before reinstalling the float switch assembly.
