Dear Mr. Charles Weaver,
April 15, 2024
RECEIVED
MAY 0 6 2024
NCDEQ/DWR/NPDES
Enclosed please find information supporting an application for a discharge system for a 3-
Bedroom Single Family Residence (SFR) located in Durham County, North Carolina. The
proposed system will replace a failing unpermitted discharging sand filter system that serves the
residence. The proposed system is to be sized for 3 bedrooms and has been designed to convey
all wastewater from the SFR, including greywater, to the proposed septic tank.
The following information is included with this letter:
Notice of Intent (NCG550000).
$60 check payable to North Carolina DENR.
Documentation from Durham County Department of
Public Health
- Letter requesting coverage under the General Permit.
- Letter requesting Authorization to Construct.
- Soils Evaluation report by Chris McGee, L.S.S. of AWT, Inc.
- Correspondence from USGS.
- Flow Path to "Blue Line" Water Feature.
- Information on Connecting to Regional Sewer.
- Engineering Alternatives Analysis (EAA).
- Local Government Review Forms.
- Plans and Specifications for the Proposed System.

The proposed discharge location is into a yard inlet on the southwest corner of the
property. The system discharges to a currently permitted flow path that flows to an
unnamed tributary to Lick Creek. The flow path is included in Attachment G. The
discharge system will utilize the following components:
- Septic Tank with Effluent Filter
- Recirculation Pump Chamber (Integrated into AdvanTex Pod System)
- Discharge Pump Chamber (Integrated into Advantex Pod System)
- AdvanTex Treatment Pod
- UV Disinfection
Discharge Point with Rip -Rap
Flow Path to "Blue Line" Water Feature
The proposed discharge location is to a yard inlet on the property that flows to an
unnamed tributary to Lick Creek. A map showing the path from the discharge
point to the first "blue -line" stream, as shown on the Durham County GIS Map,
can be seen in Attachment G. The system discharges into a currently permitted
flow path. The latitudinal and longitudinal information presented below is the
approximate location of the confluence of the unnamed tributary with Lick Creek.
Receiving Stream Lick Creek
Stream Index 27-11-(0.5)
Stream Class WS-IV; NSW
Latitude 35.9660
Longitude-79.7840
Notice of Intent
As part of the Notice of Intent, the feasibility of alternatives to discharging must be
addressed. The following alternatives are to be evaluated:
Connection to a regional or municipal sewer collection system.
Letter from the local or county health department describing the suitability
or non -suitability of the site for all types of wastewater ground adsorption
and innovative non -discharge systems, as well as documenting the repair
potential of the failed system.
Investigate land application such as spray irrigation or drip irrigation.
Connection to a Regional or Municipal Sewer Collection System
Connection to a sewer collection system is not feasible for this facility. Brian Cradle,
Engineering Specialist at City of Durham Engineering Services Group, indicated that the
property is not within Durham County sewer coverage area. The closest current city -
maintained sewer is approximately 1,100 linear ft. from the property and there are no
immediate plans for a sewer extension to the area at this time (Attachment H). At an
estimate of $150/ft, the sewer extension would cost over $165,000.

Letter from the local or county health department describing the suitability or non -
suitability of the site for all types of wastewater ground adsorption and innovative
non -discharge systems. Document the repair potential of the failed system.
The Durham County Department of Public Health indicated that the site is unsuitable for
installation of a ground absorption septic system in a denial letter dated October 16, 2019
(Attachment B). The letter indicated that a repair permit cannot be issued due to
insufficient space, unsuitable soil depth, and unsuitable soil wetness conditions.
Investigate Land Application such as spray irrigation or drip irrigation.
Per the soil evaluation by Bailey Stiles of Agri -Waste Technology, Inc., the soils on the
subject properties are unsuitable for conventional and alternative subsurface wastewater
systems due to unsuitable soil wetness condition, insufficient available space, and
unsuitable soil depth. Surface application/irrigation systems do not qualify for this lot
due to insufficient space based on required setbacks, slope, and depth to restrictive
features limiting soil water movement (Attachment E).
7Q10 Flow Estimate
The United States Geological Survey (USGS) was contacted to determine the 7Q10 flow
estimate for the proposed wastewater discharge point. The proposed discharge point
flows into an unnamed tributary to Lick Creek. The analysis from USGS indicates the
7Q10 discharge for the point in question is likely zero (Attachment F).
Engineering Alternatives Analysis
An Engineering Alternatives Analysis (EAA) has been completed for this site and
is included as Attachment I. In my opinion, the completed EAA demonstrates
that a wastewater treatment system permitted under the NCG550000 General
Discharge Permit is the only feasible option for this site. We have exhausted all
other options for this site as follows:
a.) connection to a municipal or regional sewer collection system
- Not feasible due to costs.
b.) subsurface disposal
- Inadequate soil for a subsurface absorption system.
c.) single-family residence wastewater irrigation (drip and spray)
- Inadequate soil and insufficient space for a non -discharge
ground absorption system.
d.) reclaimed -water systems
- Inadequate soil and not feasible due to fill soil costs for a
reclaimed water system. No reasonable ability to operate
as a bulk distributor of reclaimed water.
e.) Any viable combination of the above
- There are no viable combinations of the above due to soil
and cost limitations.

Local Government Review Forms
As part of the EAA, Local Government Review Forms were sent to Durham County and
the City of Durham. A copy of the submittal is included as Attachment J. To date, the
Durham County form and the City of Durham forms have yet to be signed and returned.
I appreciate your time and efforts in reviewing this application. If you have any
questions or comments, please feel free to contact me at 919-859-0669.

Dear Ms. Stinnett,
On October 9, 2019, the Durham County Department of Public Health, Environmental Health
Division on evaluated the above referenced property at the site designated on the plat/site
plan that accompanied your Construction Authorization to Repair application. According to
your application the site is a single family dwelling with a design wastewater flow of 360
gallons per day. The evaluation was done in accordance with the laws and rules governing
wastewater systems in North Carolina General Statute 130A-333 including related statutes
and Title 15A, Subchapter 18A, of the North Carolina Administrative Code, Rule .1900 and
related rules.
Based on the criteria set out in Title 15A, Subchapter 18A, of the North Carolina Administrative
Code, Rule .1940 through .1948, the evaluation indicated that the site is UNSUITABLE for a
sanitary system of sewage treatment and disposal. Therefore, we must deny your request for
an Authorization to Construct. A copy of the site evaluation is enclosed. The site is unsuitable
based on the following:
Unsuitable soil topography and/or landscape position (Rule .1940)
Unsuitable soil characteristics (structure or clay mineralogy) (Rule .1941)
Unsuitable soil wetness condition (Rule .1942)
Unsuitable soil depth (Rule .1943)
0 Presence of restrictive horizon (Rule .1944)
© Insufficient space for septic system and repair area (Rule .1945)
Unsuitable for meeting required setbacks (Rule .1950)
These severe soil or site limitations could cause premature system failure, leading to the
discharge of untreated sewage on the ground surface, into surface waters, directly to ground
water or inside your structure.
The site evaluation included consideration of possible site modifications, as well as use of
modified, innovative, or alternative systems. However, the Health Department has determined
that none of the above options will overcome the severe conditions on this site. A possible
option might be a system designed to dispose of sewage to another area of suitable soil or off -
site to additional property.
For the reasons set out above, the property is currently classified UNSUITABLE, and no
construction authorization permit shall be issued for this site in accordance with Rule .1948(c).

Note that a site classified as UNSUITABLE may be classified as PROVISIONALLY SUITABLE if
written documentation is provided that meets the requirements of Rule .1948(d). A copy of this
rule is enclosed. You may hire a consultant to assist you if you wish to try to develop a plan
under which your site could be reclassified as PROVISIONALLY SUITABLE.
You have a right to an informal review of this decision. You may request an informal review by
the soil scientist or environmental health supervisor at the local health department. You may
also request an informal review by the North Carolina Department of Health and Human
Services regional soil scientist. A request for informal review must be made in writing to the
local health department.
You also have a right to a formal appeal of this decision. To pursue a formal appeal, you must

operation of a ground absorption sewage treatment and disposal system or have slight limitations that are readily
overcome by proper design and installation.
(b) Sites classified as PROVISIONALLY SUITABLE may be utilized for a ground absorption sewage treatment and
disposal_ system consistent with these Rules but have moderate limitations. Sites classified Provisionally Suitable
require some modifications. and careful planning, design, and installation in order for a ground absorption sewage
treatment and disposal system to function satisfactorily.
(c) Sites classified UNSUITABLE have severe -limitations for the installation and use of a properly functioning ground
absorption sewage treatment and disposal system. An improvement permit shall not be issued for a site which is
classified as UNSUITABLE. However, where a site is UNSUITABLE, it. may be reclassified PROVISIONALLY
SUITABLE if a special investigation indicates that a modified or alternative system can be installed in accordance with
Rules .1956 or .1957 of this Section.
(d) A site classified as UNSUITABLE may be used for a ground absorption sewage treatment and disposal system
specifically identified in Rules .1955, .1956, or .1957 of this Section or a system approved under Rule .1969 if written
documentation; including engineering, hydrogeologic, geologic or soil studies, indicates to the local health department
that the proposed system can be expected to function satisfactorily. Such. sites shall be reclassified as
PROVISIONALLY SUITABLE if the local health department determines that the substantiating data indicate that:
(1) a ground absorption system can be installed so that the effluent will be non-pathogenic, non-infectious,
non -toxic, and non -hazardous;
(2) the effluent. will not contaminate groundwater or surface water; and
(3) the effluent will not be exposed on the ground surface or be discharged to surface waters where it could
come in contact with people, animals, or vectors.
The State shall review the substantiating data if requested by the local health department.

Environmental Health Division file number: 290297
Dear Ms. Stinnett,
On October 9, 2019, the Durham County Department of Public Health, Environmental Health
Division on evaluated the above referenced property at the site designated on the plat/site
plan that accompanied your Construction Authorization to Repair application. According to
your application the site is a single family dwelling with a design wastewater flow of 360
gallons per day. The evaluation was done in accordance with the laws and rules governing
wastewater systems in North Carolina General Statute 130A-333 including related statutes
and Title 15A, Subchapter 18A, of the North Carolina Administrative Code, Rule .1900 and
related rules.
Based on the criteria set out in Title 15A, Subchapter 18A, of the North Carolina Administrative
Code, Rule .1940 through .1948, the evaluation indicated that the site is UNSUITABLE for a
sanitary system of sewage treatment and disposal. Therefore, we must deny your request for
an Authorization to Construct. A copy of the site evaluation is enclosed. The site is unsuitable
based on the following:
Unsuitable soil topography and/or landscape position (Rule .1940)
0 Unsuitable soil characteristics (structure or clay mineralogy) (Rule .1941)
Unsuitable soil wetness condition (Rule .1942)
Unsuitable soil depth (Rule .1943)
Presence of restrictive horizon (Rule .1944)
© Insufficient space for septic system and repair area (Rule .1945)
0 Unsuitable for meeting required setbacks (Rule .1950)
These severe soil or site limitations could cause premature system failure, leading to the
discharge of untreated sewage on the ground surface, into surface waters, directly to ground
water or inside your structure.
The site evaluation included consideration of possible site modifications, as well as use of
modified, innovative, or alternative systems. However, the Health Department has determined
that none of the above options will overcome the severe conditions on this site. A possible
option might be a system designed to dispose of sewage to another area of suitable soil or off -
site to additional property.
For the reasons set out above, the property is currently classified UNSUITABLE, and no
construction authorization permit shall be issued for this site in accordance with Rule .1948(c).

Note that a site classified as UNSUITABLE may be classified as PROVISIONALLY SUITABLE if
written documentation is provided that meets the requirements of Rule .1948(d). A copy of this
rule is enclosed. You may hire a consultant to assist you if you wish to try to develop a plan
under which your site could be reclassified as PROVISIONALLY SUITABLE.
You have a right to an informal review of this decision. You may request an informal review by
the soil scientist or environmental health supervisor at the local health department. You may
also request an informal review by the North Carolina Department of Health and Human
Services regional soil scientist. A request for informal review must be made in writing to the

You also have a right to a formal appeal of this decision. To pursue a formal appeal, you must
file a petition for a contested case hearing with the Office of Administrative Hearings, 6714 Mail
Service Center, Raleigh, NC 27699-6714. To get a copy of a petition form, you may write the
Office of Administrative Hearings or call the office at [phone] or download it from the
OAH web site at http://www.ncoah.com/forms.html . The petition for a contested case hearing
must be filed in accordance with the provision of North Carolina General Statutes 130A-24 and
150E-23 and all other applicable provisions of Chapter 150B. N.C. General Statute 130A-335
(g) provides that your hearing would be held in the county where your property is located.
Please note: If you wish to pursue a formal appeal, you must file the petition form with the Office
of Administrative Hearings WITHIN 30 DAYS OF THE DATE OF THIS LETTER. The date of
this letter is November 17, 2019. Meeting the 30 day deadline is critical to your formal appeal.
If you file a petition for a contested case hearing with the Office of Administrative Hearings, you
are required by law (N.C. General Statute 15013-23) to serve a copy of your petition on the
Office of General Counsel, N.C. Department of Health and Human Services, 2001 Mail Service
Center, Raleigh, N.C. 27699-2001.
Do not serve the petition on your local health department. Sending a copy of your petition to the
local health department will not satisfy the legal requirement in N.C. General Statute 15OB-23
that you send a copy to the Office of General Counsel, N. C. Department of Health and Human
Services.
You may call or write the local health department if you need any additional information or
assistance.

Soils Evaluation Summary
TO: Doug Waggoner, Client
FROM: Chris McGee, LSS & Bailey Stiles
SUBJECT: Soils Evaluation for 330 Olive Branch Road, Durham, NC (Durham County)
Agri -Waste Technology, Inc. (AWT) was contracted to perform a soils and site evaluation for
the purpose of on -site wastewater system suitability at the subject property in Durham, NC. The
evaluation was performed by Bailey Stiles of AWT. A single-family residence with an existing
sand filter bed system is located on the property. The lot has been evaluated by the Durham
County Environmental Health Department and deemed to be unsuitable for any subsurface on -
site wastewater system option.
The soils on the subject properties are unsuitable for conventional and alternative subsurface
wastewater systems due to unsuitable soil wetness condition, insufficient available space, and
unsuitable soil depth. Surface application/irrigation systems do not qualify for this lot due to
insufficient space based on required setbacks, slope, and depth to restrictive features limiting soil
water movement.
Therefore, the property does not comply with the requirements of 15A NCAC 18A Section
.1900 — Sewage Treatment and Disposal Systems -or- 15A NCAC 02T Section .0600 — SFR
Wastewater Irrigation Systems. The site is a likely candidate for a surface water discharge
system.
Please contact us with any questions, concerns, or comments.

The drainage area for this discharge location is approximately 0.02 sq.mi. Given the drainage area is less than 0.1 sq. miles
the USGS streamflow records for extremely small basins are very limited to almost non-existent for North Carolina streams,
and all low -flow characteristics (7Q10, 30Q2, W7Q10, and 7Q2) for these small drainage basins are presumed to be zero
flow or less than minimal flow (0.05 cfs). Moreover, this drainage area is located in Zone HA6. Still the drainage area is
below the threshold of 50 sq.mi. It remains to assume zero flow or less than minimal flow (0.05 cfs).

Good afternoon,
Engineering can only see that there is no current access to water and sewer on Olive Branch at this time.
There does appear to be a water line on Rondelay Dr. that is pending city acceptance right now but it
would still need to be extending down Olive Brach Rd. in order to connect to services. (You would need to
speak with a civil engineer to get costs once the lines are in place and to discuss extending them to your
address)

Engineering Alternatives Analysis (EAA) Guidance Document
North Carolina Division of Water Resources
STEP 1. Determine if the proposed discharge will be allowed
Before beginning any engineering evaluation of alternatives, you must first determine if the proposed
wastewater discharge will be allowed. Otherwise, time and money may be spent needlessly for an EAA
preparation that will ultimately be rejected on the basis of existing water quality restrictions. There are
several potential restrictions to a wastewater discharge to surface waters, including:
■ Zero flow stream restrictions [15A NCAC 2B.0206(d)(2)] apply to oxygen -consuming waste in
zero -flow streams. In order to determine streamflow at the proposed discharge location, contact
the U.S. Geological Survey at 919-571-4000.
■ Receiving stream classification restrictions [e.g., ORW, WS, SA, NSW, and HQ class waters
have various discharge restrictions or require stricter treatment standards]. Stream
classifications are available on the the DWR Classification and Standards/Rule Review Branch
website: (http://portal.ncdenr.org/web/wq/ps/csu), while wastewater discharge restrictions
for various stream classifications are presented in state regulations [ 15A NCAC 2B.02001.
■ Basinwide Water Quality Plans. These basin -specific plans list NPDES permitting strategies
that may limit wastewater discharges to particular streams within the basin due to lack of stream
assimilative capacity, etc. Basin plans are available on the DWR website, or you may contact the
DWR Basinwide Planning Branch (http://portaLncdenr.org/web/wq/ps/bpu)..
■ Impaired waters and TMDLs. Certain waterbodies listed as impaired on the 303(d) list and/or
subject to impending TMDLs may have wastewater discharge restrictions. The list of 303(d)
impaired waters is located on the DWR website, or you may contact the DWR Modeling and
Assessment Branch (http://portal.ncdenr.org/web/wq/ps/mtu).
■ Presence of Endangered Species. If endangered species are present in the proposed discharge
location, there may be wastewater discharge restrictions. Endangered species information may
be included in the Basinwide Water Quality Plan, or you may contact the U.S. Fish and Wildlife
Service (919-856-4520), N.C. Wildlife Resources Commission (919-733-3633), or the N.C. Natural
Heritage Program (919-733-7701).
Municipal applicants.
As a public service, the NPDES Unit will evaluate whether a proposed municipal discharge is considered
allowable. The municipality needs to initiate this review by submitting a letter request for Speculative
Effluent Limits to the NPDES Unit. You must obtain streamflow estimates for the proposed discharge
location to ensure that the receiving stream is not subject to zero flow restrictions. Low flow data
(specifically, drainage area, summer and winter 7Q10, average flow and 30Q2 flow statistics) can be obtained
for a nominal fee from the U.S. Geological Survey in Raleigh at 919-571-4000. The low flow data must be
submitted with the speculative limits request letter. If the proposed discharge appears to be allowable, the
NPDES Unit will prepare speculative effluent limits for a maximum of 2 flows and 2 discharge locations using
water quality models. The municipality can then use the speculative limits to prepare preliminary
engineering design and cost estimates for the direct discharge alternative within the EAA. In limited
instances where complex water quality models are necessary to develop speculative limits and determine
potential water quality impacts, some municipalities have undertaken the modeling effort (with DWR review)
in order to expedite this portion of the NPDES permit review process.
Response: N/A Non -municipal applicant
EAA Guidance Document Revision: October 2019
Page I of 12

Non -municipal applicants.
Due to staff' constraints, the NPDES Unit cannot prepare speculative limits for non -municipal applicants.
Thus, it is your responsibility to make your own determination as to whether the proposed discharge might be
allowed by the Division, by evaluating the water quality factors listed above. It is highly recommended that
you discuss the proposed discharge with the applicable DWR Regional Office and/or NPDES Unit staff, who
may be able to provide input on the likelihood of a new/expanding discharge. As a first step, you must
obtain streamflow estimates for the proposed discharge location to ensure that the receiving stream is not
subject to zero flow restrictions. Low flow data (specifically, drainage area, the summer and winter 7Q10,
average flow and 30Q2 flow statistics) can be obtained for a nominal fee from the U.S. Geological Survey in
Raleigh at 919-571-4000. The low flow data must be submitted with the EAA, and will be used by the permit
writer to develop permit limits. You must also verify that the proposed action (i.e., construction of a
wastewater treatment plant and its appurtenances) is consistent with local zoning and/or subdivision
ordinances. You will need to request the local government(s) to complete a Local Government Review Form
(Attachment A), and include the signed and notarized form with your NPDES application package.
Response: The United States Geological Survey (USGS) was contacted to determine the 7Q10 flow estimate for the
downstream tributary of the proposed wastewater discharge point. The proposed discharge location is to a yard
inlet on the southwest corner of the property that flows to an unnamed tributary to Lick Creek. The analysis from
USGS indicates the 7Q10 discharge for the point in question is likely zero (Appendix G ofpackage).
All applicants.
If you conclude that the proposed discharge will pass the "allowable discharge" criteria, then begin the EAA
preparation by summarizing the following general information about the proposed project:
■ Provide a description of the proposed project. If the project will be constructed in phases,
provide a schedule for constructing each additional phase, and provide the projected flow per
phase (see STEP 2).
Response: A wastewater discharge system is to be constructed for a 3-Bedroom Single Family Residence (SFR) located in
Durham County, North Carolina. The proposed system will replace a failing sand filter system that currently
serves the residence. The proposed discharge location is into a yard inlet on the southwest corner of the property.
The system discharges to a currently permitted flow path that flows to an unnamed tributary to Lick Creek. The
proposed treatment system will utilize the following components:
- Septic Tank with Effluent Filter
- Recirculation Pump Chamber (Integrated into AdvanTex Pod System)
- Discharge Pump Chamber (Integrated into AdvanTex Pod System)
- AdvanTex AX-20-RT pod
- UV Disinfection
- Discharge Point with Rip -Rap
Construction of the proposed system will occur in a single phase with an anticipated completion time of
approximately 2 weeks after the start of construction activity.

STEP 2. Provide reasonable projections for population and flow
Residential Population Projections.
Facilities requesting an NPDES discharge permit for new or expanding domestic wastewater discharges
must document the population to be served within the service area over a 20-year planning period. The NC
State Demographics unit provides population data for each county and municipality and can be accessed on
the Internet at http://www.demog.state.nc.us. If 20-year population projections for specific areas are not
available, a linear extrapolation of population trends from the past decade should be used. Any deviation
from a linear projection method must be clearly justified. If population projections include future
annexations, include a proposed annexation schedule as well as any annexation requirements that must be
met.
Response: Because the wastewater treatment system is designed for a single-family residence, the population to be served
will be limited by the number of bedrooms at the individual residence. The existing house contains 3 bedrooms.
For the 20-year planning period, the system will be designed for a 3-bedroom residence with a flow of 360
gallons per day. At 2 people per bedroom, the system will be designed to serve 6 residents.
Municipal Flow Projections.
Justification of flow as well as a demonstration of need shall be provided. Mere speculation is not sufficient.
Flow projections should represent average anticipated flows, since permit flow limits are based on monthly
averages. Peaking factors used to design various components of the wastewater collection system (e.g.,
collector sewers, interceptor sewers, pumping stations) should not be used in the justification of the average
anticipated flow. For municipal wastewater dischargers, flow must be justified using the Clean Water Loan
Program (CWLP) Guidance for Preparing Engineering Reports available on the Internet at
http://portal.ncdenr.org/web/wi/cleanwater/er. Exceptions to these flow criteria may be approved on a
case -by -case basis provided adequate justification is supplied.
Current Flow- Provide current flows including residential, commercial, industrial, and
infiltration/inflow (I/I) based on actual flow data or water billing records. Current residential
flow and current commercial flow may be based on water billing records minus a 10%
consumptive loss. Current industrial flow may be based on dual metering to determine
consumptive losses.
Future Residential Flow- Provide 20-year residential flows based on projected residential growth.
Multiply the projected growth in residential population by 70 gallons per day per capita.
EAA Guidance Document Revision: October 2019
Page 3 of 12

Future Commercial Flow- Provide 20-year commercial flows based on projected residential
growth. Multiply the projected growth in residential population by 15 gallons per day per capita.
Future Industrial Flow- Provide flow for future documented industrial flow. A nominal
allowance for future unplanned industrial expansions may be considered by the Division,
provided the basis is clearly justified and current land -use plans and local zoning allow for such
industrial growth.
Response: N/A Non -municipal applicant
Non -Municipal Flow Projections.
Flow may be justified in accordance with 15A NCAC 2H .0219(1) for various activities (e.g., new
subdivisions, new schools, various commercial activities). For other proposed discharges (e.g.,
groundwater remediation, water treatment plant filter backwash, industrial facilities), the flow projections
will be based on engineering design considerations and/or production projections rather than population
projections.
Response. Because the wastewater treatment system is designed for a single-family residence, the population to be served
will be limited by the number of bedrooms at the individual residence. The existing house contains 3 bedrooms.
For the 20-year planning period, the system will be designed for a 3 bedroom residence with a flow of 360
gallons per day. At 2 people per bedroom, the system will be designed to serve 6 residents.
STEP 3. Evaluate technologically feasible alternatives
Since a goal of the Clean Water Act is to minimize or eliminate point source discharges to surface waters,
any proposal for a new or expanding wastewater discharge must include evaluation of wastewater disposal
alternatives in addition to direct discharge. Particularly for dischargers of domestic wastewater, this
evaluation should investigate the feasibility of the following wastewater disposal alternatives:
■ Connection to an existing wastewater treatment plant (public or private)
■ Land application alternatives, such as individual/community onsite subsurface systems, drip
irrigation, spray irrigation
■ Wastewater reuse
■ Surface water discharge through the NPDES program
■ Combinations of the above
In order for the applicant to eliminate a wastewater disposal alternative, you must either show that the
alternative is technologically infeasible, or that it would be cost prohibitive to implement relative to a direct
discharge alternative. Please note that for some alternatives, it might be easier to prove an alternative is not
viable based on high cost rather than technological feasibility. For example, for a large municipal expansion
that would require several hundred acres for a land application alternative, it might be easier to simply
assume that the required acreage could be purchased and calculate the present value costs (including current
market land costs) for this option, rather than evaluating whether land application is technologically
infeasible due to lack of available land and/or poor soil conditions. For those alternatives identified as
technologically feasible, you must develop and compare costs, based on a preliminary level design effort (see
STEP 4).
The Division recognizes that wastewater disposal alternatives may be limited for some non -domestic
wastewater scenarios, and a full alternatives evaluation may not be warranted. If there is some question as to
whether an alternative may be eliminated, contact the NPDES Unit staff. Some scenarios that might not
require a full alternatives evaluation include:
EAA Guidance Document Revision: October 2019
Page 4 of 12

Water Treatment Plant Discharges. Discharges from water treatment plants (WTPs) that utilize
a membrane technology (e.g., reverse osmosis, nanofiltration) or ion exchange system tend to
generate highly concentrated wastestreams. These wastestreams are not amenable to land
application and do not have to be evaluated for this alternative. However, since these
wastestreams can also have a toxic impact on a receiving freshwater system, proposed new
discharges from these WTPs to freshwaters will not be considered for an NPDES permit unless
you can demonstrate that the environmental impacts would be minimal based on dilution
modeling. You should investigate whether the wastewater can be piped to a stream with
sufficient dilution, or whether a local WWTP might accommodate this discharge. Please note
that discharges from WTPs that utilize greensand filtration or conventional technology produce
a wastestream that is not saline, therefore no disposal alternatives can be automatically ruled out
as infeasible for these other WTPs. Refer to the NPDES website for permitting strategies for
reverse osmosis, ion exchange, greensand filtration, and conventional WTPs.
Groundwater Remediation System Discharges. You will need to evaluate whether WWTP
connection, land application, infiltration galleries, in -situ groundwater remediation wells, or
closed -loop groundwater remediation wells are viable disposal alternatives. While land
application might be a feasible alternative in rural areas, it would not be a feasible alternative in
downtown Charlotte, where there is no land available for wastewater application. In this
instance, you may simply state that land application is infeasible based on land constraints
within the city. You will also need to evaluate connection to an existing WWTP (in accordance
with Alternative A), since there are some municipalities that have accepted this waste stream in
the past. If the municipality will not accept the waste stream, the connection alternative is also
considered technologically infeasible. Please note that in -situ and closed -loop groundwater
remediation wells are permittable well types and further guidance is available through the
Aquifer Protection Section.
Aside from these exceptions, you should proceed with the alternatives evaluation in accordance with the
following requirements. If you have any questions about these requirements, contact the NPDES Unit staff.
Alternative A. Connection to an Existing Wastewater Treatment System.
You must evaluate the feasibility of connecting to an existing wastewater treatment system served by a
municipality or other entity holding a valid NPDES or Non -Discharge Permit. All connection options
should include an evaluation of a gravity line and/or force main with pump station(s).
1. Existing Sewerage System:
(a) Identify whether there are existing sewer lines within a five -mile radius, or consider a greater
radius if cost effective for the project size.
Response: Connection to a sewer collection system is not feasible for this facility. Brian Cradle, Engineering Specialist at
City of Durham Engineering Services Group, indicated that the nearest city -maintained sewer is approximately
1,100 linear feet from the property. At an estimate of $150/ft, a sewer extension would cost over $165,000. There
are no plans for a sewer extension to the area.
(b) Provide a preliminary indication of flow acceptance from existing municipal or private
WWI Ps under consideration for connection. If a municipal or private WWI P cannot accept
the wastewater, include a letter documenting such and consider this alternative
technologically infeasible.
Response: N/A No sewerage available
EAA Guidance Document Revision: October 2019
Page 5 of 12

(c) If an existing sewerage system will accept the wastewater, evaluate the
piping/pumps/resources necessary to connect to the existing wastewater treatment plant.
Attach a topographic map or a site drawing showing the physical route of this alternative.
Conduct a Present Value Cost Analysis per STEP 4.
Response: N/A No sewerage available
2. Planned Sewerage System: Determine if a regional sewerage system within a five -mile radius is
projected to be available within the next five years to receive waste from the project site. If
applicable, determine availability date and flow acceptance projection from appropriate
authority.
Response. As stated above, the property is not able to access city sewerage.
Alternative B. Land 4plication.
Land application disposal alternatives include individual/community onsite subsurface systems, drip
irrigation, and spray irrigation.
1. Provide an estimate of the best case hydraulic loading rate based on County Soil Surveys or from
a soil evaluation performed by a soil scientist. Include calculations showing the hydraulic
loading rate and the total area of land needed for the land disposal system, including buffers.
Response: Per the soil evaluation by Chris McGee of Agri -Waste Technology, Inc., the site does not have suitable soil to
accommodate a ground absorption or surface drip or surface spray wastewater system. (Appendix E of package)
Regardless of the fact that a subsurface ground absorption system cannot be designed or permitted for this site,
the potential size of a subsurface system has been estimated in the table below.

The current property's land available for the sub -surface system is 14,625 sq. ft. with setbacks and existing site
conditions. A schematic of this area is shown in Appendix A of the EAA. The land needed for a subsurface
dripfield design is a minimum of 4,800 sq. ft., so there may be sufficient space for this type of system at the
residence. However, the soils are unsuitable for supporting this type of system.
EAA Guidance Document Revision: October 2019

For a surface system in this soil, the SFR loading rate group is likely restricted to a maximum annual loading
of 19.5 in/year. The sizing calculation for a non -discharge surface system is summarized in the table below:

The current property's land available for the system is 2,488 sq ft. A schematic of this area is shown in
Appendix A. The land needed for a non -discharge application system is estimated at 10,810 sq. ft., so there is
not sufficient space for a non -discharge surface system, and the unsuitable soil conditions do not allow for a
non -discharge surface system.
2. Assess the availability of land. If insufficient land is available onsite, assume that the necessary
land can be purchased and estimate the land purchase cost based on local real estate prices.
Alternatively, provide documentation to demonstrate that insufficient land is available for sale in
the project area (include letters from adjacent property owners indicating no interest in selling
property).
Response: The table below lists neighboring properties and the value of the land as listed by the Orange County GIS
website. The surrounding lots contain single-family residences. The values listed in the table do not reflect
the value of single-family residences.

3. Provide a description of the wastewater treatment system and the non -discharge application
system. Include a site plan showing the proposed layout, the application area, any existing
structures, proposed structures, and other uses within the site.
Response: A typical subsurface drip system or a non -discharge surface spray or surface drip system with pretreatment
considers the following components:
- Septic Tank with Effluent Filter
- Recirculation Tank (Integrated in AX20-RT unit)
- AdvanTex Treatment Pod (1 AX20 Pod)
- Pump Tank (potentially integrated in AX20-RT unit)
- UV Disinfection (Integrated in AX20-RT unit)
- Headworks Box
- Control Panel
- Disposal Field (drip or spray)
Note: The proposed discharge system does not consider the pump tank, headworks box or disposal field.
Site drawings of these alternative systems showing the available application area are included as Appendix A
of the EAA. Due to the limitations caused by the soil characteristics and conditions, there is no ability to
consider any of these systems on this property.
4. Explain the proposed reuse plan if reclaimed water will be used by a third party.
Response. There is no reuse plan being considered either on -site or by a third party. The existing residential plumbing
infrastructure does not allow for reuse in the existing residence. It is not feasible to consider using reclaimed
water on the site or becoming a bulk distributor of reclaimed water. The table below summarizes the
amount of reclaimed water that could be beneficially used on site. As shown, there may be sufficient area to
utilize the daily flow of reclaimed water, however; a reclaimed system would be cost prohibitive for a
single-family residence.

5. Conduct a Present Value Cost Analysis per STEP 4. For the reclaimed water system include the
potential revenue generated by selling the water.
Response. A Present Value Cost Analysis is included as Appendix B of the EAA. An analysis was performed for a
sub -surface drip system, a non -discharge surface application system, and a reclaimed water system. A
summary of the analysis is included in STEP 4.
6. Provide all calculations, documentation, and maps as necessary to support assumptions and
conclusions.
Response: Calculations performed to evaluate land application alternatives are shown in Alternative B.
EAA Guidance Document Revision: October 2019
Page 8 of 12

7. Note: The design of land application systems must meet the treatment and design requirements
specified in 15A NCAC 21r.05 or 15A NCAC 18A.1900.
Response: The treatment systems specified above in Step B would meet the treatment standards required by these rules
as they pertain to single family residences. However, because of the lack of available space due to
unsuitable soil conditions, no land -based systems can be considered.
8. Note: Proposed discharges from groundwater remediation systems must evaluate the potential
for an infiltration gallery treatment alternative.
Response: N/A
Alternative C. Wastewater Reuse.
You must evaluate reusing all or a portion of the wastewater generated. Some municipalities are currently
reusing wastewater within the confines of their WWTP property for irrigation, toilet flushing, backwashing,
etc., while other municipalities have established progressive reuse programs for residential irrigation. Reuse
applications might include golf course irrigation, crop irrigation (e.g., hardwood or pine plantation,
grasses), athletic field irrigation, landscape uses, and commercial/industrial uses. Some of these reuse
applications will be evaluated under Alternative B, Land Application. The design of reclaimed water
systems must meet the treatment and design requirements specified in 15A NCAC 2U.
Response: All reuse applications for this project scale were evaluated under Alternative B, Step 4. Wastewater reuse
was determined to be infeasible for this project.
Alternative D. Direct Discharge to Surface Waters.
1. No new or expanding (additional) discharge of oxygen -consuming waste will be allowed to
surface waters of North Carolina if both the summer 7Q10 and 30Q2 streamflows are estimated
to be zero, in accordance with 15A NCAC 2B.0206(d). Private applicants must contact the USGS
in Raleigh at 919-571-4000 and obtain (generally for a nominal fee), the receiving streamflow data
(7Q10, 30Q2, annual average streamflow) at the proposed discharge location. This information
must be included in the EAA, and will be used to develop permit limits.
Response. Because there is an estimated zero flow at the discharge point, the discharge will be considered on a case -by -
case basis. The proposed discharge is 360 gpd.
2. All direct discharge systems of oxygen -consuming wastes should be evaluated both with tertiary
filtration [BOD5= 5 mg/l, NH3-N= 1 mg/11 and without, and assuming a weekly sampling
regime.
Response: Tertiary filtration is not required under the general permit, as the general permit requirements (monthly
average) are BOD5 = 30 mg/l and Total Suspended Solids = 30 mg/l. However, based on actual sample
results from similar treatment systems (other facilities using the same technology) in many cases, a B0135 of
5 mg/l and NH3-N of 1 mg/l can be met. While weekly sampling of the treated effluent would confirm the
treatment results on a regular basis, the additional cost associated with the collection and testing of the
effluent would not be feasible for the homeowner.
3. Provide a description of the proposed wastewater treatment facilities, including a schematic
diagram of the major components and a site plan of the treatment facility with outfall line(s).
Response: Plans and schematic drawings can be found in Attachment B (of original application package).
4. Provide documentation of the availability of required land and/or easement agreements.
Response: The proposed discharge system will be located on land owned by the applicant. See Attachment B (of
original application package) for the proposed discharge system location.
EAA Guidance Document Revision: October 2019
Page 9 of 12

5. Conduct a Present Value Cost Analysis per STEP 4.
Response: A Present Value Cost Analysis for the discharge system is included in Appendix B. A summary of the
analysis is included in STEP 4.
6. Note: All direct discharge treatment systems must comply with Reliability Requirements
specified in 15A NCAC 2H.0124.
Response: The system serves a private facility that is served by a private well and does not have elevated water storage
tanks. In the event of a power outage, water will not be available to the residence. There is storage available
in the system to hold some waste from the house until power is restored to the system. If the power is out
for an extended period, ceasing water usage in the house or pumping of the septic tank may be required.
Alternative E. Combination of Alternatives.
You should evaluate the possibility of a combination of wastewater alternatives that would minimize or
eliminate a direct discharge alternative. For example, consider whether the facility can operate a land
application system during the dry season when streamflows are at their lowest and provide less dilution, and
operate an NPDES discharge system during the wet season when soils may not be as amenable to land
application and the receiving stream provides its greatest dilution.
Response. A non -discharge alternative is not feasible due to the soil constraints listed in Alternative B. The presence or
absence of a seasonal high-water table will not relieve the other constraints.
STEP 4. Evaluate economic feasibility of alternatives
To provide valid cost comparisons among all technologically feasible wastewater alternatives identified in
STEP 3, a 20-year Present Value of Costs Analysis (PVCA) must be performed. A preliminary design level
effort is considered appropriate for comparing feasible options and their associated costs. For the PVCA cost
comparison, all future expenditures are converted to a present value cost at the beginning of the 20-year
planning period. A discount rate is used in the analysis and represents the time value of money (the ability of
money to earn interest). Present value is also referred to as "present discounted value" or "present worth".
The PVCA should include all monetary costs associated with construction, startup and annual operation and
maintenance of a facility. All unit cost information must be provided, and costs must be referenced. Costs
can be referenced in paragraph format by summarizing the sources utilized (e.g., vendor quotes, realtor land
quotes, past bids, Means Construction Index, etc). Vender quotes received for treatment units or other
components, as well as realtor land quotes, shall be included as well. For each treatment alternative
identified as technologically feasible, costs should include, but not be limited to, the following:
Capital Costs
■ Land acquisition costs
■ Equipment costs
■ Labor costs
■ Installation costs
■ Design costs
EAA Guidance Document Revision: October 2019
Page 10 of 12

Recurring Costs
■ Operation and maintenance costs (with replacement costs)
■ Laboratory costs assuming a weekly monitoring regime for discharge systems and a monthly
regime for non -discharge systems
■ Operator and support staff costs
■ Residual disposal costs
■ Connection fees and subsequent user fees
Permit and compliance fees
Utility costs (power, water, etc.)
Lost Opportunity Costs
PVCA Calculation Method.
The following standard formula for computing the present value must be used in all cost estimates made
under this evaluation:
Where:
PV=C° +z C'
,=1 (1 + r)`
PV = Present value of costs.
Co = Costs incurred in the present year.
Ct = Costs incurred in time t.
t = Time period after the present year (The present year is t = 0)
n = Ending year of the life of the facility.
r = Current EPA discount rate. EPA adjusts this rate annually on October 1, and it can be
accessed from the Internet at http:/www.nccgl.net/fap/cwsrf/201gui.html.
If recurring costs are the same in years 1 through 20, then Ct=C and the formula reduces to:
PV=C +Cf (l+r)"-11
° LL r(1+rr J
As an example, assuming capital costs (Co) of $2 million, annual recurring costs (C) of $40,000, and a
discount rate (r) of 5.625%, the 20-year (n=20) present value of costs would equal:
PV= capital costs + recurring costs X
PV= $2,000,000 + $40,000 X
PV= $2,000,000 + $471,428
PV= $2,471,428
[(1+0.05625)20 —11 / [0.05625(1+0.05625)20 ]
[1.98/0.168]
EAA Guidance Document Reuision: October 2019

PVCA Summary Table.
The EAA must include a Summary Cost Table, which summarizes present worth costs developed for all
technologically feasible wastewater alternatives. The summary should include a breakdown of capital costs
and recurring costs. In some situations, the Division may require the applicant to refine cost estimates for
some alternatives, or possibly collect actual soil data to better characterize the land application alternative.
Ultimately, the final determination on cost effectiveness is made by the Division with consideration of
monetary costs as well as potential environmental impacts.
Response. The following table presents the cost analysis for several types of wastewater systems. Given the
information presented above, the only technologically feasible alternative is the Discharge System. The
"Install Cost" includes the estimated cost to design and install the specific type of system. The "Present
Value of Costs" is based on a discount factor of 2.50%.

RE: Local Government Review Form
Application for Discharge System — Doug Waggoner
330 Olive Branch Rd, Durham, NC 27703
Dear Dr. Sowell,
February 22, 2024
Enclosed please find a Local Government Review Form required for an Authorization to
Construct application supporting a proposed wastewater treatment system. The proposed
system will be permitted under the NCG550000 General Discharge Permit for Single Family
Residences. The proposed system will serve a 3-Bedroom Single Family residence (SFR)
located in Durham County, North Carolina. The proposed system will replace the failing,
unpermitted discharging sand filter system that currently serves the residence.
This site has been deemed unsuitable for ground absorption sewage treatment systems by the
Durham County Public Health Department due to unsuitable soil conditions and insufficient
space. It is my opinion that a wastewater treatment system covered by the General Discharge
Permit is the only technologically and economically feasible option for this residence.
Please complete the enclosed form for inclusion in the application for the proposed system.
The residence is located in Durham County. Please note that this form is only meant to
determine zoning/jurisdiction information for the county and does not indicate your approval
of the proposed system.
I appreciate your time and efforts in completing this form. If you have any questions or
comments, please feel free to contact me at 919-859-0669.
Best Regards,

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 septic tank will include an
effluent filter and risers. An Orenco 8" Biotube effluent filter will be installed in the outlet end of
the septic tank. New access risers will be installed on both the inlet and outlet ends of the septic
tank. To facilitate the installation of the access risers, riser adapters will be cast into the tank top
during construction. All wastewater from the single-family residence, including greywater, will be
routed into the septic tank. Waste that exits the septic tank will flow 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 exits the AX-RT unit via
gravity to the discharge outlet. Prior to exiting the AX-RT unit, effluent passes through the UV
disinfection system.
The recirculation pump is controlled by a system of 3 floats that operate the recirculation pump in a
Timed Dose arrangement. Float 1 (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 for a pre-set time period, the High Water Alarm will activate.

The discharge pump is located on the outlet side of the treatment pod. Flow to the discharge outlet is
managed using three (3) floats that control the discharge pump in a Demand Dose arrangement (due
to the timed dosed arrangement of the recirculation pump, in essence the discharge dosing pump is
timed dosed as well). Float 1 (lowest elevation is a "Pump OFF" float. Float 2 is the "Pump ON"
float, while Float 3 acts as a High Water alarm. Under normal operation, once the Pump OFF and
Pump ON floats are engaged, the pump will send effluent to the discharge outlet. The discharge
pump will shut-off once the Pump OFF float drops due to the dropping water level.
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 yard inlet on the southwest corner of the property which flows to an
unnamed tributary of Lick Creek. 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 re -circulation pump and UV system. If desired, this panel can be connected to a land based
phone line that will notify the operator of system operation.

Omnco Sy"ems
800-348-9843
Orenco's PRTA tank adapters are molded plastic products and
therefore have excellent part -quality and consistency. PRTA
tank adapters can be cast into a tank or fastened to the top
of the tank with a bolt -down kit. The bolt -down kit consists of
either six or twelve (depending on model) stainless steel con-
crete anchors and a roll of butyl tape.
The O.D. of the vertical flange matches the I.D. of Orenco's
ribbed risers, which provides a suitable joint to seal with
MA320, ADH100, SS115, or SS140 adhesive.

Access Risers and Tank Adapters CCeSy
aterns'
800-3rpo48-9843
Installation Instructions
Access risers provide access to septic tank openings, simplifying inspection and maintenance procedures. It is important
that the riser be sized correctly and installed properly (i.e., appropriate tank adapter, attachment method, etc.) to ensure a
watertight seal. Without a watertight seal, groundwater or surface water can leak into the tank, reducing the tank's perfor-
mance. When setting a riser, orient the grommets in the appropriate directions before bonding to the tank.
In this document, metric equivalents are omitted for nominal dimensions, such as riser and pipe diameters. If you are using
pipe other than IPS standard sizes, consult your Distributor for adapters you may need.
Riser Sizing
The installed riser should extend about 3 in. (76 mm) above the finished ground level (approximately 2 in. [51 mm] for tank
settlement and 1 in. [25 mm] to ensure drainage away from the riser). If the riser is too long, it may be cut to the appropri-
ate height using a circular saw or table saw. Always cut excess length from the bottom of the riser. To ensure a good fit and
watertight joint, a square cut is essential. If the riser is too short, a grade ring may be used as an extension.
Selecting a Riser and Tank Adapter Installation Method
To select an appropriate riser and tank adapter installation method, first determine the type of tank being used: concrete or
fiberglass. Then refer to the chart below, as you follow these steps:
Concrete Tanks
1. Determine desired riser diameter.
2. Determine if the riser tank adapter will be cast -in or bolted down.
3. Referring to the chart below, pick the appropriate tank adapter for your riser diameter and method of attachment.
If the bolt -down method is being used, make sure the adapter you selected will cover the tank's opening.
Orenco Fiberglass Tanks (contact your distributor or Orenco for other fiberglass tanks)
1. For 30-in. riser, choose the FRTA30-FRP tank adapter.
2. For 24-in. riser, no adapter is needed; 24-in. riser fits tank directly.

About Adhesives
ADH100 is a single -component adhesive/sealant for sealing pipe grom-
mets and joining PVC or fiberglass risers to ABS or fiberglass PRTA-
style tank adapters (where the joint is in shear). Handling strength is
achieved within 12 hours, and full cure in 2 to 3 days. It comes in a
10.2-oz (300-mL) cartridge tube for application with a caulking gun.
ADH10 QPS810) adhesive is a white, two -component, self -leveling
methacrylate adhesive for bonding PVC, ABS, fiberglass, and concrete.
ADH10 comes in pint (500-mL) and quart (1000-mL) kits, consisting of
A and B components (adhesive and activator), and requires hand mix-
ing. If a self -leveling adhesive is NOT required or if concrete is NOT
being bonded, SS115 or SS140 is preferred over ADH10.
ADH845 adhesive is a tan two -component methacrylate adhesive for
bonding PVC, ABS, fiberglass, and concrete. This is our only adhesive
formulated to work in wet conditions or even under water, making it
ideal for field repairs. Repairs on leaking riser connections are pos-
sible, but any water pressure must be removed during the repair.
ADH845 has the consistency of molasses, comes in 400-mL cartridges,
and requires the manual dispensing gun ADH845-GUN.
MA320 is a white two -component methacrylate adhesive that bonds
PVC, ABS and fiberglass to themselves or each other, but does not
bond to concrete. It comes in a two-part 200-gram see -through plastic
pouch that must be kneaded to mix the two components, then cut open
and squeezed to apply adhesive.
SS140 adhesive is a gray two -component methacrylate adhesive for
bonding PVC and fiberglass to themselves or each other. It does not
bond to concrete. It has the consistency of toothpaste and will sag
slightly in warmer temperatures. Surface roughening is recommended
and provides the best bond strengths, but is not always necessary. Use
SS140 above 65° F (180 C) and SS115 below 500 F (100 C). Working life
of mixed adhesive is typically 20 to 30 minutes, and it usually hardens
in less than 2 hours, depending on temperature and adhesive thick-
ness. It comes in an 870-mLtwo-part cartridge and can be dispensed
from pneumatic gun SS-MK or, for occasional use, manual gun SS-MK-
MANUAL GUN.
SS115 adhesive is a white two -component methacrylate adhesive with
properties similar to those of SS140 and comes in the same two-part
cartridge, but has a much shorter open time for use in cooler tempera-
tures and jobs where quicker cure times are desired, or for applica-
tions where a white color is desired. Working life of mixed adhesive is
typically 10 to 15 minutes, and it usually hardens in less than 45 min-

Installation Instructions (continued)
Cast -in PRTA30 tank adapter
Instruction Set 2: Cast -In Adapters
Adapter type used: PRTA24 or PRTA30
Adhesive used: ADH100, MA320, SS115, or SS140
Bolt -down kit used: None
Step 2a: Apply Adhesive
Apply adhesive to the outside surface of the riser tank adapter.
Hint: If you plan to backfill the same day, the use of MA320, SS115 or
SS140 adhesive is recommended because of their quicker cure times.
If you have multiple riser installations and do not have bulk adhesive
(SS115/SS140), consider using both MA320 and ADH100. Apply just
enough MA320 on the outside of the tank adapter for a quick structural
joint (cure time is typically less than an hour). A single package of
MA320 can be used to provide a structural joint on two or three risers.
Then apply ADH100 to the inside of the adapter and the riser joint, for a
watertight seal.
Step 2b: Place Riser
Orient the riser correctly and carefully slide it onto the adapter before
the adhesive cures.
Step 2c: Seal Adapter -to -Riser Joint
Apply adhesive to the inside of the adapter and riser joint. Use a putty
knife or similar tool to form a continuous fillet between the tank adapter
and the inside of the riser.
Step 2d: Cure Adhesive
Allow adhesive to harden before baWilling. For ADH100, handling
strength is typically achieved within 12 hours. For MA320, cure time is
achieved within 30 minutes to 3 hours, depending on temperature.

Installing Grommets
Step 1: Mark the Riser
To install grommets in the field, first mark the riser for location of the
grommets. (For Perma-Loc risers, you should try to avoid
cutting through the pipe seam —the extra thick rib — unless it is
unavoidable.)
Step 2: Notch the Ribs
Using a 4-in. (100-mm) grinder or other cutting tool, notch through the
PVC ribs to the wall of the PVC riser. Remove an area of ribbing equal
to approximately 1 in. (25 mm) larger than the grommet diameter.
Step 3: Remove the Ribs
Using a hammer and chisel, break the notched ribs from the riser. Use a
grinder to remove any remaining rib material so that you are left with a
smooth area, ensuring a watertight fit. (Hole saws with attached pocket
cutters are available from Orenco; they cut away the ribs as the hole is
cut, eliminating the need to notch and break the ribs.)
Step 4: Cut the Hole
Using the Grommet Hole Saw Sizing Chart below, select a hole saw
for the grommet installation and drill out the opening. (If you are using
pipe and grommets other than U.S. nominal sizes, ascertain the correct
hole size for your grommet.) Use a deburring tool or knife to deburr the
edges of the opening, being careful not to enlarge the
opening.

dimensions and actual pipe
O.D., see Orenco's Grommet
Submittal (NSU-RLA-PG-1),
available from the Document
Library at wwworenco.com.
Install the grommet in the riser. Apply a bead of ADH100 adhesive to
the groove of the grommet before inserting it into the riser hole. This
will make the grommet more secure and will overcome any imperfec-
tions in the drilled hole.

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.

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.

External Splice Box
Applications
The Orenco' External Splice Box attaches outside the access
riser of an underground tank. It is engineered specificallyfor
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 isolation of high and low
voltage wires where needed. It has four cord grips which accom-
modate 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 is provided with a hole -cutting template to simplify installa-
tion on the riser.
General
To specify the Orenco External Splice Box for your installation,
require the following:
• Watertight 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 100 in? (1639 cm3) for easy wiring access and to
accommodate multiple wiring configurations
• Bottom entry, so conduit or direct -bury cable always remains
below minimum burial depth
• Molded of UL (fl) rated plastic, resistant to cold and UV
exposure, suitable for external applications
• Optional divider plates available for isolating high and low vol-
tage wires from separate conduits or direct -bury cable
The External Splice Box is molded of a UL
(fl) rated PVC alloy. It has a UL Type 6P list-
ing for prolonged submergence.

AdvanTexO AX-RT Treatment Systems
Applications
Orenco's AdvanTexy 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:
• 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
same dependable, textile treatment media found in all AdvanTex prod-
ucts.

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.
Key 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.
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 la: 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:
I& Key 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 A 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).
QKey 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.

(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 1i8 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.
NANome: 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 2: Perform Excavation(s), conL
Step 2c: Make sure the bottom of the excavation is suitable for setting the
AX-RT unit and (f needed) the tank: stable, smooth, level, and free of debris,
rocks, and other sharp objects.
n
Key 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 s Y2- to s --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) r
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 75701) Fiberglass Tanks,
OIMPORTANT Take care to keep everyone clear of the excavation
Men placing the tank.
Key Points.
• The tank has to be set at the correct depth to connect to the sewage inlet.
• A minimum fall of 1A inch per foot (10 mm per meter or 1 e/6) 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.

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.
QKey Points:
• 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 free of voids, with
smooth, continuous fillets.
• 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.
Key Points:

Installation Steps
Step 5: Install Antibuoyancy Deadmen (If Needed), coot.
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 backfillingi 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.
4�is 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 (> Win. or 19-mm)
rocks, sharp rocks, peat, or muck. In these cases, use s 3/4 inch (s 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.

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.

Step 16: Complete Backfilling
QKey Points:
• When backfilling, be careful not to alter the slope of 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.
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 (> %4-in. or 19-mm)
rocks, sharp rocks, peat, or muck. In these cases, use s 3/4-in. (s 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 Winch 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, Appendb(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 sift, 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.
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 (gpm or L/sec) 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 — the value, measured in gpm, expressed by the first two numerals in an Orenco pump nomenclature. These graphs use solid lines to show the
optimal pump operation range. Dashed lines indicate flow rates outside of the optimal range for each pump. For the most accurate pump specifica-
tions, use Orenco's PumpSelect" software.

AXB Control Panels
Applications
VeriComm" AX131 and AXB2 remote telemetry control panels are
used with two -pump operations — recirculation and discharge
(on -demand or timed) — for AdvanTex Treatment Systems.
Interlocked controls prevent the recirculation pump from running
if there is a high level alarm on the discharge side. 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 effi-
ciency, while remaining invisible to the homeowner. VeriComm
AXB panels allow remote operators to change system param-
eters, including timer settings, from the Web interface.
Typical AXB_ VenComml Control Panel
Standard Models: VCOM AXB 1, VCOM AXB2
To Specify...
To specify this panel for your installation, require the following:
Basic Control Logic: Three Operating Modes
• A "Start-up Mode" for the initial 30 days, during which the
system collects trend data to establish operating standards for
future reference.
• 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/
homeowner 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.

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.
Step 1:
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.
Step Z
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.

Installation Instructions (continued)
Step 3:
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.
Step 4:
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.
Step 5:
Replace the float switch assembly in the holding bracket. Make sure the
assembly snaps fully into the bracket.
Step 6:
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.

Step 7:
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.

Maintenance Instructions °a
Oreneo Systems'
Incorporated
1-800-348-9843
During the annual inspection, follow the testing procedures provided to ensure that the system is operating properly. If afloat 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.

UV Disinfection Unit
Applications
The Orenco' UV Disinfection Unit can be used after secondary
treatment (10 mg/L CBODJSS) in applications requiring disinfec-
tion before dispersal.
In NSF Standard 40 testing for fecal coliform reduction using typi-
cal residential flows of 500 gpd (1890 L/day), the UV Disinfection
Unit reduced fecal coliform by 99.9 percent (3 logs). Specifically,
it yielded an overall geometric mean of 1.71 cfu/100 mL. The bulb
used in testing was rated at 125 pW/cml intensity.
This test used effluent treated by an AdvanTex' AX20 Treatment
System, which produced effluent of 4 mg/L CBOD5, 6 mg/L TSS,
and 1.2 NTU, with a geometric mean of 1.35 x 10'cfu/100mL.
Similar reductions in fecal coliform can be expected from other
secondary treatment systems that produce 10 mg/L CBOD5 and
TSS in the field.
For information on commercial or high -flow applications, contact
Orenco's Engineered Systems department.

General
In a pump or gravity discharge basin or tank, treated effluent is
disinfected as it flows through the housing and around the UV
lamp. The unit uses no chemicals and has no moving parts. It
requires annual cleaning and lamp replacement.
Features/Specifications
To specify this component for your secondary treatment system,
require the following:
For all secondary treatment systems:
• Require a secondary treatment system that produces
10 mg/L CBOD5 and TSS in the field.
• Require a power ballast and lamp current sensor housed in a
control panel (not a tank or riser) to minimize corrosion and
failure due to environmental exposure.
• Require a quartz sheath to minimize buildup and service
intervals
Power cord
Require a quick -disconnect fitting for easy inspection and
Cord grip
cleaning.
For Orenco's AdvanTex Treatment Systems:
Lamp handle
Require suitability with Orenco MVP Panels or the VeriComm"
Monitoring System. When coupled with an AdvanTex
Treatment System, the MVP panel or VeriComm Monitoring
System prevents discharge of non -disinfected effluent due to
lamp failure. A current sensor monitors lamp function and, in
Outlet
the event of lamp failure, the AdvanTex discharge pump is
automatically disabled. With MVP panels, an audible and
visible alarm is activated. With VeriComm-equipped systems
a text alert is sent to the Service Provider.
