RE: Application for Discharge System — Broch Property
Lower Beaverdam Loop Road, Candler, NC 28715 (PIN: 9605-25-0161)
Dear Mr. Weaver,
January 30, 2024
Enclosed, please find information supporting an application for a discharge system for a Single -
Family Residence (SFR) with Accessory Dwelling Units and Workshop located in Buncombe
County, North Carolina. The site has been deemed unsuitable for ground absorption sewage
treatment systems by the Buncombe County Environmental Health Department due to unsuitable
soil wetness conditions, unsuitable soil depth, and insufficient space.
The lot was previously permitted in 2022 under the NPDES Discharge Permit (NC0090018)
with the owner's intention to develop a tiny home community. The owner has since decided to
develop the lot as a single-family residence. Upon issuance of the Certificate of Coverage under
NCG55, the owner will request to rescind the NPDES individual permit.
The proposed system is to be sized for 985 gallons per day and has been designed to convey all
wastewater from the SFR, including greywater, to the new septic tank. This application is being
submitted with the intent to have coverage under the NCG55 General Permit.
The following information is included with this letter:
Notice of Intent (NCG550000).
$60 check payable to North Carolina DENR.
Documentation from Buncombe County Health Department.
- Letter requesting coverage under the General Permit.
- Letter requesting Authorization to Construct.
- Soils Evaluation report by Walker Ferguson, L.S.S.
- 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 directly into Beaverdam Creek, located along Lower
Beaverdam Loop Road. The discharge system will utilize the following components:
- Grinder Basin at Storage Workshop
- New Septic Tank with Effluent Filter
- Future Septic Tank with Effluent Filter (for Future 2-BDR ADU)
- Recirculation Tank with Recirculation pump
- AdvanTex Treatment Pods (2)
- UV Disinfection
- Control Panel
- Discharge Point with Rip -Rap
Flow Path to "Blue Line" Water Feature
The proposed discharge location is into a portion of Beaverdam Creek that is
located on the applicant's property. A map showing the path from the discharge
point to the first "blue -line" stream, as shown on the NCDEQ Stream
Classification Map, can be seen in Attachment G. The latitudinal and longitudinal
information presented below is the approximate location of the confluence of
Beaverdam Creek.

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.
- 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 property. Mr. Hunter
Carson, Director of Engineering with the Metropolitan Sewerage District of Buncombe
County indicated that the closest sewer system is over 18,000 linear feet from the
applicant's property. At an estimated cost of $1501ft, the cost to extend the sewer line
would exceed $2,700,000 (plus engineering and tap fees). The correspondence with
MSD Planning and Development is included in Attachment H.
2 of 151

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 Buncombe County Environmental Health Department indicated that the site is
unsuitable for installation of a ground absorption septic system in a letter dated January
24, 2024 (Attachment B). The letter indicated that a permit cannot be issued due to
unsuitable soil characteristics.
Investigate Land Application such as spray irrigation or drip irrigation.
Per the soil evaluation by Walker Ferguson, L.S.S. of Land Resource Management, the
site does not have sufficient space or suitable soil characteristics to accommodate a non -
discharge surface spray or drip wastewater system (Attachment E).
7Q10 Flow Estimate
The United States Geological Survey (USGS) was contacted to determine the 7Q 10 flow
estimate for the proposed wastewater discharge point. The proposed discharge point is
Beaverdam Creek. The analysis from USGS is included in 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 Buncombe County
and the City of Asheville. A copy of the submittal is included as Attachment J. To date,
the completed forms have not been received.

Dear Dreamstaff Holdings, LLC
C/O Zachary Broch
The Buncombe County Health and Human Services, Environmental Health Division on _1/24/24 evaluated the above -
referenced property at the site designated on the plat/site plan that accompanied your application. According to your application the
site is to serve one single family residence with accessory dwellings and workshop for a total of 8 bedrooms with a design
wastewater flow of 985 gallons per day." The evaluation was done in accordance with the laws and rules governing
wastewater systems in North Carolina General Statute 130A-333 and 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, Rules .1940 through .1948, the
evaluation indicated that the site is UNSUITABLE for a ground absorption sewage system. Therefore, your request for an improvement
permit is DENIED. 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)
X_ Unsuitable soil wetness condition (Rule .1942)
XA Unsuitable soil depth (Rule .1943)
Presence of restrictive horizon (Rule .1944)
X_ Insufficient space for septic system and repair area (Rule .1945)
Unsuitable for meeting required setbacks (Rule .1950)
Other (Rule .1946)
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 Division of Environmental Health 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 improvement permit shall be issued for this
site in accordance with Rule .1948(c),

Accessory Dwelling Units and Workshop located in Buncombe County, North Carolina. The site
has been deemed unsuitable for ground absorption sewage treatment systems by the Buncombe
County Environmental Health Department due to unsuitable soil characteristics. The proposed
system is to be sized for 985 gallons/day. The residence is located at Beaverdam Loop Road,
Candler, NC 28715 (PIN: 9605-25-0161).
Thank you for your assistance in this matter.

Regarding: Report of Findings
Preliminary Soils Evaluation
Parcel ID # 9605-25-0161
TBD Beaverdam Loop Road, Buncombe County, NC
LRM Project# 78020
Dear Mr. Broch:
Land Resource Management, PLLC (LRM) has conducted a preliminary soils investigation
on 6.19 Acres off Beaverdam Loop Road in Buncombe County, North Carolina. Based on
this soils evaluation, LRM has determined the 6.19 acre parcel is suitable for a single 4
bedroom aerobic subsurface drip irrigation (SSDI) onsite wastewater system.
The preliminary soils evaluation and recommendation is based on, observations made and
data collected on topography, landscape position, parent material, underlying geology, and
soil characteristics. Soil characteristics include, but are not limited to, depth to a Seasonal
High Water Table (SHWT), depth to a restrictive horizon, total soil depth, soil horizonation,
soil structure, soil color, clay mineralogy, bulk density, consistence, plasticity, stone
content, and percent sand, silt, clay, and mica. They follow the guidelines set forth in the
North Carolina Administrative Code -Rules for Sewage Treatment and Disposal Systems,
Title 15A-DENR, Subchapter 18A, Section .1934 through .1970, amended October 1 st,
2011.
Thank you for this opportunity to provide you with soils data and interpretation. Please let
us know if any assistance is needed in obtaining a septic permit from Buncombe County
Health Department.
Sincerely,
Walker Ferguson, LSS

USGS response to DWR USGS Low Flows request # 2020-94 (dated 2020/09/03) for
Beaverdam Creek Buncombe County ... RE: [EXTERNAL] 7Q10/30Q2 Request-
Streamstat Basin Del for Lucas Property Buncombe Co. NC

Ms. Davidson,
In response to your inquiry about the low -flow characteristics for a location on Beaverdam Creek at
Beaverdam in southwestern Buncombe County, the following information is provided:
A check of the low -flow files here at the USGS South Atlantic Water Science Center (Raleigh office) does not
indicates a previous low -flow determination for the point of interest, identified by the lat/long coordinates
(35.49441,-82.68926) provided via email dated 09/03/2020 from the DWR USGS Low Flow portal following
your request submission.
In the absence of site -specific discharge records sufficient for a low -flow analysis, estimates of low -flow
characteristics at ungaged locations are determined by assessing a range in the low -flow yields (expressed as
flow per square mile drainage area, or cfsm) at nearby sites where estimates have previously been
determined.
A basin delineation completed using the online USGS StreamStats application for North Carolina
(https://streamstats.usgs.gov/ss/) indicates the drainage area for the point of interest (StreamStats adjusted
coordinates 35.49441,-82.68926 NAD83) is 4.69 sgmi, which confirms the drainage area submitted as part of
the request information.
For streams in Buncombe County, low -flow characteristics published by the USGS are provided in the
following reports:
(1) The first is a statewide report completed in the early 1990's. It is USGS Water -Supply Paper 2403, "Low -
flow characteristics of streams in North Carolina" (Giese and Mason, 1993). An online version of the report is
available at https-.//pubs.usgs.gov/wsp/­Z40/­repQrt.pdf. The report provides the low -flow characteristics
(based on data through 1988) via regional relations and at -site values for sites with drainage basins between 1
and 400 sgmi and not considered or known to be affected by regulation and/or diversions.
(2) The second is a statewide report published in March 2015. It is USGS Scientific Investigations Report
2015-5001, "Low -flow characteristics and flow -duration statistics for selected USGS continuous -record
streamgaging stations in North Carolina through 2012" (Weaver, 2015). The report is available online at
https://pubs.usgs.gov/sir/2015/5001/. The report provides updated low -flow characteristics and flow -
duration statistics for 266 active (as of 2012 water year) and discontinued streamgages across the state where
a minimum of 10 climatic years discharge records were available for flow analyses.
Low -flow characteristics estimated for point of interest:
Inspection of the reports indicates the presence of ten (10) nearby selected USGS partial -record sites (5) and
continuous -record streamgages (5) in the general vicinity of the point of interest where low -flow

characteristics were published. Among these 10 index sites, the low -flow discharge yields for the indicated
flow statistics are as follows:
Annual 7Q10 low -flow yields =_> from 0.22 to 0.56 cfsm (average about 0.36 cfsm, median about 0.39 cfsm)
Annual 30Q2 low -flow yields =_> from 0.43 to 1 cfsm (average about 0.73 cfsm, median about 0.76 cfsm)
Winter 7Q10 low -flow yields =_> from 0.3 to 0.69 cfsm (average about 0.49 cfsm, median about 0.51 cfsm)
Annual 7Q2 low -flow yields ==> from 0.36 to 0.87 cfsm (both average and median about 0.62 cfsm)
Average annual discharge yields ==> from 1.1 to 3.2 cfsm (average about 2 cfsm, median about 2.4 cfsm)
Application of the above range in yields to the drainage area (4.69 sgmi) for the point of interest results in the
following estimated low -flow discharges:
Annual 7Q10 low -flow discharges =_> from 1 to 2.6 cfs (average about 1.7 cfs, median about 1.8 cfs)
Annual 30Q2 low -flow discharges =_> from 2 to 4.7 cfs (average about 3.4 cfs, median about 3.6 cfs)
Winter 7Q10 low -flow discharges =_> from 1.4 to 3.2 cfs (average about 2.3 cfs, median about 2.4 cfs)
Annual 7Q2 low -flow discharges ==> from 1.7 to 4.1 cfs (both average and median about 2.9 cfs)
Average annual discharge discharges ==> from 5.2 to 15 cfs (average about 9.4 cfs, median about 11.3 cfs)
Please note:
(1) The estimated flows are provided in units of cubic feet per second (cfs).
(2) The low -flow yields provided above are rounded to 2 significant figures. Estimated low -flow discharges less
than 1 cfs are rounded to 2 significant figures. If between 1 and 100 cfs, then rounded to 1 decimal place; if
greater than 100, then rounded to the nearest whole number (zero decimal places).
(3) The information provided in this message is based on a preliminary assessment and considered
provisional, subject to revision pending collection of future data and further analyses.
These provisional streamflow statistics are provided via the DWR USGS Low Flows cooperative agreement
between the USGS and the N.C. Department of Environmental Quality, Division of Water Resources.
Hope this information is helpful.
Thank you.

Engineering Alternatives Analysis (EAA) Guidance Document
North Carolina Division of Water Resources
NOTE: The N.C. Division of Water Resources (DWR) will not accept an NPDES application for a new or
expanding wastewater treatment plant discharge unless all the required application requirements are
submitted. A complete NPDES application will include the following items:
NPDES Application Form (in triplicate)
Application Fee
Engineering Alternatives Analysis (in triplicate)
Local Government Review Form (non -municipals only)
Failure to submit all of the required information will result in return of the incomplete package. If you have
any questions about these requirements, contact the NPDES Unit staff. Contact names, application forms,
applicable fees, and guidance documents are available on the NPDES website at:
https: / /deq.nc.gov/about/divisions /water -resources /water -resources -permits /wastewater-branch/npdes-
wastewater-permits. Completed applications should be mailed to: NCDENR/DWR/NPDES Complex
Permitting Unit,1617 Mail Service Center, Raleigh, NC 27699-1617.
Background
The NPDES permit program was enacted in 1972 as part of the Clean Water Act. The original goal of the
program was to eliminate all point source discharges to surface waters by 1985. Although this goal was not
achieved, the NPDES program continues to strive toward it. In that light, an Engineering Alternatives
Analysis (EAA) is required with any NPDES application for a new or expanding wastewater treatment plant
discharge, in accordance with 15A NCAC 2H.0105(c)(2). In order for an NPDES application to be
approved, the EAA must provide complete justification for a direct discharge to surface water alternative,
and demonstrate that direct discharge is the most environmentally sound alternative selected from all
reasonably cost-effective options [per 15A NCAC 2H.0105(c)(2)].
The purpose of this EAA Guidance Document is to provide guidance to the regulated community for the
evaluation of wastewater disposal alternatives. The impetus behind this comprehensive guidance was based
on the following: 1) a majority of new NPDES applications were being returned as incomplete due to
inadequate EAA submissions; and 2) a few recent court cases resulted in unfavorable rulings for the NPDES
discharger due in part to inadequate EAAs. DWR most frequently returns EAAs as incomplete due to
inadequate flow justification, inadequate alternatives evaluations, and/or lack of documentation/references
used to design and cost alternatives.
Please note that this guidance document is designed primarily for domestic wastewater discharges. For other
proposed discharges such as water treatment plant discharges from ion exchange and reverse osmosis units,
some alternative disposal options may not be technologically feasible. Within this guidance document, we
have attempted to point out where such technological limitations may exist. You are urged to review NPDES
permitting guidance documents on the NPDES website, which discuss some of the limited disposal options
for some discharges.
Please note that if a proposed municipal expansion is subject to SEPA Environmental Assessment
(EA)/Environmental Impact Statement (EIS) requirements, the EAA requirements should be incorporated
into the SEPA document. In addition, the NPDES Unit cannot accept an application for a new/expanding
NPDES discharge until departmental review of the SEPA document is complete and a Finding of No
Significant Impact (FONSI) has been submitted to the State Clearinghouse for circulation.
EAA Guidance Document Revision: October 2019
Page 1 of 14
41 of 151

The following step-by-step outline should be used for the preparation of all EAA submissions. If an EAA
submission lacks any of these basic elements, the NPDES application will be returned as incomplete.
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://portal.ncdenr.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

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 directly
into Beaverdam Creek located on the applicant's property. The analysis from USGS indicates the 7Q10
discharge for the point in question (Attachment F of application package).
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 Single -Family Residence (SFR) with Accessory
dwellings and workshop located in Buncombe County, North Carolina. The proposed discharge location is
directly into Beaverdam Creek. The proposed treatment system will utilize the following components:
- Grinder Basin at Storage Workshop
- New Septic Tank with Effluent Filter
- Future Septic Tank with Effluent Filter (for Future 2-BDR ADU)
- Recirculation Tank with Recirculation Pump
- AdvanTex Treatment Pods (2)
- UV Disinfection
- Control Panel
- 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 with accessory dwellings, the
population to be served will be limited by the number of bedrooms at the individual residence. The total flow is
comparable to an 8-bedroom single-family residence. For the 20-year planning period, the system will be
designed with a flow of 985 gallons per day. At 2 people per bedroom, the system will be designed to serve 16
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 4 of 14
44 of 151

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 with accessory dwellings and
workshop, the population to be served will be limited by the number of bedrooms at the individual residence.
The total flow is comparable to an 8-bedroom single-family residence. For the 20-year planning period, the
system will be designed with a flow of 985 gallons per day. At 2 people per bedroom, the system will be
designed to serve 16 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 5 of 14
45 of 151

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. Mr. Hunter Carson, Director of
Engineering with the Metropolitan Sewerage District of Buncombe County indicated that the property is over
18,000 linear feet from existing public sewer infrastructure. The Metropolitan Sewerage District has no plans of
extending sewer in that direction. Therefore, it is not accessible for the property in question. The correspondence
with Mr. Carson is included in Attachment H.
Extending sewer would be a minimum of 18,000 feet. For reference, if an installation cost of $1501ft of installed
sewer line was assumed, the cost to connect this property to the sewer line would be approximately $2,700,000.
Additional costs including the cost of the pump station, potential "tap" or sewer capital fees, road repair costs,
frontage fees and fees for right of way permits would also be incurred by the homeowner.
(b) Provide a preliminary indication of flow acceptance from existing municipal or private
WWTPs under consideration for connection. If a municipal or private WWTP cannot accept
the wastewater, include a letter documenting such and consider this alternative
technologically infeasible.
EAA Guidance Document Revision: October 2019
Page 6 of 14
46 of 151

Response: N/A No sewerage available
(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: There are currently no plans for the Metropolitan Sewerage District of Buncombe County to provide sewerage to
the area and it is expected that this will be the case for at least the next five years. Sewer extensions are driven by
development, and the Metropolitan Sewerage District does not have plans of extending the sewer in this
direction. No other regionally planned sewerage systems have been identified.
Alternative B. Land Application.
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: The Buncombe County Environmental Health Department indicated that the site is unsuitable for installation of
a ground absorption septic system in a letter dated January 24, 2024 (Attachment B of application package). The
letter indicated that the lot is unsuitable for ground absorption sewage treatment systems due to unsuitable soil
characteristics and insufficient space.
Per the soil evaluation by Walker Ferguson, L.S.S. of Land Resource Management, the site does not have
adequate space or suitable soil to accommodate a ground absorption or surface drip or surface spray wastewater
system (Attachment E of application package).
Regardless of the fact that a subsurface ground absorption cannot be designed or permitted for this site, the
potential size of a subsurface system has been estimated. According to the county soil survey, the site is
classified as a Dillard Loam and Iotla Loam series soil. For a subsurface system in this soil, a drip system with
pretreatment would be required. This soil would have a long-term acceptance rate (LTAR) ranging from 0.05-
0.2 gpd/sq.ft., with a typical rate of 0.1 gpd/sq.ft. Subsurface systems also require the drainline to be installed
with the contour so that each drainline is at a constant elevation. This results in a "fanning" of the drainline and
requires additional space in order to install the required amount of drainline. The sizing calculation is
summarized in the table below:

The current property's land available for the sub -surface system is 101,250 sq. ft. due to 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 13,133 sq. ft., so there may be sufficient space for this type of
system at the residence. However, the overwhelming majority of this area contains unsuitable soil
characteristics and topography for septic.
The potential size of a non -discharge surface application system has also been estimated. According to the
county soil survey, the site is classified as Dillard Loan and Iotla Loam soil. 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 has 47,450 land available for a surface drip or spray system, due to setbacks and existing
site conditions. A schematic of this area is shown in Appendix A. The land needed for a non -discharge
application system is estimated at 29,577 sq. ft., so there may be sufficient space for this type of system at the
residence. However, the overwhelming majority of this area contains unsuitable soil characteristics and
topography for septic.
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: Because insufficient land is available onsite, offsite land was reviewed. The table below lists neighboring
properties and the value of the land as listed by the Buncombe County GIS website. The surrounding lots
contain single-family residences. The values listed in the table do not reflect the value of the single-family
residences. The soil types listed for these properties are a Dillard Loam and Iotla Loam series soil .These
sites will be very restrictive for wastewater systems.

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
- AdvanTex Treatment Pods
- Pump Tank
- UV Disinfection
- 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 size requirements of a drip or spray system and the limited available space, there is no
ability to consider any of these systems on this property. Additionally, this property is not suitable for a non -
discharge surface drip or spray system due to limitations caused by the soil characteristics and conditions.
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. 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 in Appendix A, there is not
sufficient area to utilize the daily flow of reclaimed water.

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 above in Alternative B, Points 1
and 4.
EAA Guidance Document Revision: October 2019

7. Note: The design of land application systems must meet the treatment and design requirements
specified in 15A NCAC 2T .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 and other
restrictions listed above, no land -based systems can be considered.
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, Point 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
(s7Q10, 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: 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
directly into Beaverdam Creek located on the applicant's property. The analysis from USGS indicates the
7Q10 discharge for the point in question (Attachment F of application package).
2. All direct discharge systems of oxygen -consuming wastes should be evaluated both with tertiary
filtration [BODS= 5 mg/l, NH3-N= 1 mg/1] 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/1 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 BOD5 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 K (of application package).
EAA Guidance Document Revision: October 2019
Page 10 of 14
50 of 151

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 K (of
application package) for the proposed discharge system location.
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 county -based water system and does not have elevated
water storage tanks. In the event of a power outage, water will likely 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 space and soil constraints listed in Alternative B. The
presence or absence of a seasonal high-water table will not relieve the other constraints.
EAA Guidance Document Revision: October 2019

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
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° 4-11 ct
t_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.ht".
EAA Guidance Document Revision: October 2019
Page 12 of 14
52 of 151

If recurring costs are the same in years 1 through 20, then Ct=C and the formula reduces to:
(1 + r)" —11
PV= C +
r(1+ r)"
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]
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%.

Attachment A. Local Government Review Form
General Statute Overview: North Carolina General Statute 143-215.1 (c)(6) allows input from local governments in the issuance
of NPDES Permits for non -municipal domestic wastewater treatment facilities. Specifically, the Environmental Management
Commission (EMC) may not act on an application for a new non -municipal domestic wastewater discharge facility until it has
received a written statement from each city and county government having jurisdiction over any part of the lands on which the
proposed facility and its appurtenances are to be located. The written statement shall document whether the city or county has a
zoning or subdivision ordinance in effect and (if such an ordinance is in effect) whether the proposed facility is consistent with
the ordinance. The EMC shall not approve a permit application for any facility which a city or county has determined to be
inconsistent with zoning or subdivision ordinances unless the approval of such application is determined to have statewide
significance and is in the best interest of the State.
Instructions to the Applicant: Prior to submitting an application for a NPDES Permit for a proposed facility, the applicant
shall request that both the nearby city and county government complete this form. The applicant must:
■ Submit a copy of the permit application (with a written request for this form to be completed) to the clerk of the city and
the county by certified mail, return receipt requested.
■ If either (or both) local government(s) fail(s) to mail the completed form, as evidenced by the postmark on the certified
mail card(s), within 15 days after receiving and signing for the certified mail, the applicant may submit the application to
the NPDES Unit.
■ As evidence to the Commission that the local government(s) failed to respond within 15 days, the applicant shall submit a
copy of the certified mail card along with a notarized letter stating that the local government(s) failed to respond within
the 15-day period.
Instructions to the Local Government: The nearby city and/or county government which may have or has jurisdiction over
any part of the land on which the proposed facility or its appurtenances are to be located is required to complete and return this
form to the applicant within 15 days of receipt. The form must be signed and notarized.

RE: Local Government Review Form
Application for Discharge System — Broch Property
Beaverdam Loop Road, Candler, NC 28715 (PIN: 9605-25-0161)
Dear Ms. Pinder,
October 27, 2023
Enclosed please find a Local Government Review Form required for a Certificate of
Coverage application supporting a proposed wastewater treatment system. The proposed
system will be permitted under the NCG550000 General Discharge Permit for Single Family
Residences (SFRs) and will serve a proposed SFR located in Buncombe County, North
Carolina.
The site has been deemed unsuitable for ground absorption sewage treatment systems by
Buncombe County Environmental Health 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.
This residence is located in Buncombe County.
Please note: 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 919-367-6310.
Best Regards,
Kevin Davidson, P.E.

Narrative Description of
Surface Discharge System
The designed Discharge System considers the following components:
- Grinder Basin at Storage Workshop
- New Septic Tank with Effluent Filter
- Future Septic Tank with Effluent Filter (for Future 2-BDR ADU)
- Recirculation Tank with Recirculation pump
- AdvanTex Treatment Pods (2 x AX-20)
- Recirculating Splitter Valve
- UV Disinfection
- Control Panel
- Discharge Outlet with Rip -Rap
Due to the advanced technology in this system, a Certified Operator must be contracted to
maintain this system.
Septic Tank
A new 1,500-gallon septic tank will be installed for the system. Effluent from the 4-bedroom
residence, 2-bedroom in-law suite, and grinder pump line from the storage workshop will enter the
septic tank through separate inlet boots. The septic tank will be outfitted with an 8-in. Orenco
Biotube effluent filter on the outlet. Orenco Access Risers (24 in.) will be installed on both the inlet
and outlet ends of the septic tank. To facilitate the riser installation, riser adapters will be cast into
the tank. All tank risers will contain an inner lid or approved safety device. All wastewater from the
single-family residence, including greywater, will be routed into the septic tank. Waste that exits the
septic tank will flow via gravity into the Recirculation Tank.
Future Septic Tank
A new 1,000-gallon septic tank will serve the future 2-bedroom accessory dwelling. The septic tank
will be outfitted with a 4-in. Orenco Biotube effluent filter on the outlet. Orenco Access Risers (24
in.) will be installed on both the inlet and outlet ends of the septic tank. To facilitate the riser
installation, riser adapters will be cast into the tank. All tank risers will contain an inner lid or
approved safety device. Waste that exits the septic tank will flow via gravity into the Recirculation
Tank.
75 of 151

Recirculation Tank
A new 2,000-gallon recirculation tank will be installed for this system. Waste that overflows from
the septic tank will enter the inlet end of the recirculation tank. A recirculation pump housed in a
Biotube Pump Vault will be located on the outlet end of the recirculation tank in order to deliver
effluent to the Orenco AdvanTex Treatment Pods. As liquid exits the treatment component
(AdvanTex Pod), one (1) AdvanTex Pod will flow to the recirculating splitter valve located in the
inlet riser of the recirculation tank and one (1) AdvanTex Pod will return to the recirculation tank
through the outlet boot. Access risers will be installed on both the inlet and outlet ends of the
recirculation tank. To facilitate the installation of the access risers, riser adapters will be cast into the
tank top during construction. All tank risers shall be equipped with an inner lid or approved safety
device.
AdvanTex Treatment Pod
The treatment component of the system is a re -circulating media filter system. Liquid from the re-
circulation tank will be periodically (approximately every 15 min) pumped to the pod and sprayed
over the media for treatment. The treated water will be collected via a bottom drainline and then
directed back to the re -circulation tank. The pod will be installed on a bed of gravel.
The supply line to the AdvanTex pod will also direct flow back to the septic tank. To control flow, a
ball valve will be installed on the line inside each pod.
Re -circulating Splitter Valve
The re -circulating splitter valve is located on the inlet access riser of the recirculation tank. One (1)
AdvanTex Treatment Pod will drain through the recirculating splitter valve to the disinfection
component.
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
Control Panel
One control panel will be installed with this wastewater system. This panel will control the
operation of the recirculation 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.
Discharge Outlet
The proposed discharge location is directly into Beaverdam Creek located on the subject property.
The discharge line will be buried a minimum of 18" until it reaches the discharge outlet. Riprap will
be placed at the discharge location to provide aeration of the water as it is discharged and 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.

PRTA ABS Tank Adapters
Applications
PRTA tank adapters are used to provide a structural, watertight method
of installing a 24-or 30-inch (600- or 750-mm) access riser over a tank
opening.
General
Orenco's PRTA tank adapters are molded plastic products and there-
fore 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 concrete 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 or ADH2O0
adhesive.

Introduction
These instructions are for preparing and installing access risers and grommets. Access risers provide access to septic tank openings, simplifying
inspection and maintenance procedures. Access riser -to -tank connections must be watertight for the proper functioning of an on -site septic system
or effluent sewer system. Orenco strongly recommends watertightness testing of all access riser -to -tank connections after installation.

(at 3 or 9 o'clock)
Step 1. Prepare the Riser
Step 1a. Determine how high the riser needs to be.
• The top of the riser should be about 3in (75mm) above finished
grade after installation and backfilling. This allows 2in (50mm) for
tank settling and 1 in (25mm) for ensuring drainage away from the
riser.
Step 1 b. If the riser needs to be cut to size, cut it with a circular saw
or table saw.
• Always cut excess length from the bottom of the riser.
• For square, even cuts, a good fit, and a watertight joint between
the riser and the adapter, use an Orenco riser -cutting saw guide.
Step 1 c. Use the site plans or drawings to find out if riser penetrations
are needed.
Step 1 d. Use the plans or drawing to mark the locations of the
penetrations.
• If plans or drawings aren't available, use the figure for Step 1 d as a
general guide for placing riser penetrations.
• If you have questions about where to place various riser
penetrations, contact your distributor for more information.
Step 1 e. Dry fit the riser to the adapter.
• Make sure riser penetration markings are the right sizes and in the
correct locations.
Step if. If the riser is higher than 3in (75mm) above the estimated
final grade, cut it to size per the instructions in Step 1 b.
Step 1 g. If the riser is too short, use an Orenco grade ring to extend it.

Installation Steps
Step 2. Cut Penetrations and Install Grommets
Step 2a. Drill holes for riser penetrations.
Using Orenco RKHS hole saws:
Cut the hole and grind the ribs down to make a flat, smooth surface for
installing the grommet.
• Make sure your hole saw is the correct size and your drill is
at least 18V.
• Don't grind too deeply — about 1/16in (1.6mm) is deep enough.
Using standard hole saws:
1. Use the correctly sized hole saw to cut a hole, centered on the
mark.
2. Trim the riser ribs back 1 in (25mm) from around the hole.
• Use a grinder or cutting tool to notch the ribs through to the
riser wall.
• Use a hammer and chisel to break off the notched rib sections.
• Use a grinder to make a flat, smooth surface around the hole.
Step 2b. Clean and deburr the hole and flat surface with a wire brush
and deburring knife or tool.
• Be careful not to enlarge the penetration.
Step 2c. Apply a bead of adhesive to the groove in the grommet's
outer diameter. For adhesive recommendations, see NTD-ADH-1,
Orenco Adhesives and Dispensers Technical Data Sheet.
Step 2d. Firmly press the grommet into the penetration.

Step 3a. Roughen the adapter channel and the bottom surfaces of the
riser with sandpaper.
Step 3b. Use a clean cloth and acetone or alcohol to clean the
channel and the bottom surfaces of the riser.
• The channel must be clean and dry for a good fit and watertight
joint.
• Let the acetone or alcohol dry completely.
Step 3c. Fill the channel with methacrylate adhesive.
• For adhesive recommendations, see NTD-ADH-1, OrencoAdhesives
and Dispensers Technical Data Sheet.
^,,�• NOte — If you're using a methacrylate adhesive that's
non -self -leveling, use enough to fully fill the channel, with no
voids in the adhesive.
Step 3d. Install the riser, aligning any penetrations correctly.
Step 3e. Firmly press the bottom of the riser into the channel.
• Twist the riser back and forth slightly to fully seat it and to create a
good bond.
• If the inside seam is not completely filled, add adhesive to form a
complete fillet.
Step 3f. Use a tongue depressor, putty knife, or clean cloth to make a
good fillet over the inside seam.
Note — If cold weather conditions or frost heave are a
concern at the site, contact a qualified engineer or Orenco for
additional recommendations on installing ribbed PVC risers.
IMPORTANT — orenco strongly recommends that
Oall tank risers 12in (300mm) and larger in diameter be
equipped with a secondary safety barrier to help
prevent falls or unintended entry.
Step 3g. See "Step 5. Test Riser Watertightness" on page 6 for
testing the riser's watertightness.
Note — Watertight connections are critical for the
�1 wastewater system to function effectively and efficiently.

Step 5b. Plug the inlet (and outlet, if present) of the tank with
watertight plugs.
Step 5c. Fill the tank with water to a level 2in (51 mm) into the riser.
Step 5d. Wait for the required time before inspecting the riser -to -tank
connections for leakage.
• Follow the tank manufacturer's recommendations (or applicable
local regulations) for wait times before inspecting the tank for leaks.
Step 5e. Check for any drop in the liquid level inside of the riser and
any visible leakage from the riser -to -tank connections.
• At the end of the test, there should be no drop in liquid level and no
visible leakage from seams, pinholes, or other imperfections.
• If leaks are found during the test, seal the leaks and repeat the test.
Step 5f. After the riser -to -tank connections are proven watertight,
remove the plug(s) and drop the water level in the tank to just below
the invert of the inlet or outlet, whichever is lower.

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

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

Step 1: Review or Sketch Site Plan
Check the site plan for the specifics of your installation.
QKey
Points:
• If you're installing the AX20 unit more than 20 ft (6 m) from the septic
tank, contact your Dealer for assistance.
• Confirm the treatment mode (Mode 1 or Mode 3) of the AdvanTex sys-
tem you are installing before beginning the installation. The treatment
mode is based on the system's nitrogen reduction requirements. For
more information, contact your Dealer.
Step 1 a: Detailed Site Plan Provided
Make sure that the site plan matches the site. If it doesn't, contact the
designer or engineer before you schedule the installation.
Step 1 b: Plan Of Limited Detail Or No Site Plan Provided
If you only have a plan of limited detail or no site plan, contact your Dealer
for assistance.
QKey Points:
• A minimum fall of inch per foot (20 mm per m or 2%) is required ...
From the invert of the AX20 filtrate outlet to the invert of the RSV's inlet.
From the invert of the RSV's outlet to the invert of the pump basin's inlet
(on systems with pump basins).
• If you are using a concrete tank or you are using an Orenco fiberglass
tank without a tank saddle, calculate how high the unit needs to sit
above the inlet on the RSV split flow tee. Variables include:
Length of the filtrate return line
Type of tank being used
Tank adapter style
Elevation of the RSV penetration in the access riser
Final grade of the site
• The bottom of the AX20 lid must sit at least 2 inches (50 mm) above
final grade.
• An AX20 unit can be placed in several different positions in relation to
the septic tank. If you have questions about unit placement, contact
your Dealer before continuing.
• The filtrate outlet and the recirc inlet are typically installed on opposite
sides of the AX20 unit.
• Sketch the exact positions of the system components, pipes, electrical
conduits, etc. Account for current and likely future landscape features
in the sketch. (For control panel installation, see EIN-CP-GEN-1, Panel
Installation.)
Note: If you have any questions about the key points of planning
this installation, please contact your Dealer.

Installation Steps
Step 2; Make Excavation(s) ' M
Consider the necessary elevations, offsets, and grade requirements for the
septic tank, AX20 unit, and discharge pump basin.
Step 2a: Excavate the septic tank hole. Follow the manufacturer's instructions.
• For Orenco fiberglass tanks, see NIN-TNK-1, Fiberglass Tank Burial.
Step 2b: Excavate the pump basin hole or discharge tank hole, if necessary.
Follow the manufacturer's instructions.
• The pump basin can be placed in the same excavation as the septic
tank, if there is enough room.
• If needed, you can make the pump basin excavation after you have
prepped and set the tank.
• For Orenco PVC pump basins, see NIN-PB-1, PVC Basin Installation.
Key Point. A minimum fall of 1/4 inch per foot (20 mm per m or 2%)
is required from the invert of the AX20 filtrate outlet to the invert of
the RSV's inlet and from the invert of the RSV's outlet to the invert
of the pump basin's inlet or discharge tank's inlet.
Step 2c: Excavate the AX20 hole, if it's being installed in a separate excavation
• If needed, you can make the AX20 excavation after you prep and set the
tank and (if your system includes one) the pump basin.
• Excavate a hole 8.5 ft x 4.5 ft (without antiflotation flanges) or 6 ft (with
antiflotation flanges) x up to 28 in. deep [2.6 m x 1.4 (or 1.8 m) x 0.7 ml,
depending on the fall necessary to meet requirements.
• For information on installation configurations or methods not included
in this manual, contact your Dealer.
QKey
Points:
• A minimum fall of 1/ inch per foot (20 mm per m or 2%) is required from
the invert of the AX20 filtrate outlet to the invert of the RSV's inlet.
• Allow at least 44 inches (1.1 m) between units in systems with multiple units.
• Antiflotation flanges are ...
Recommended if the AX20 unit isn't attached directly to the tank.
Required if groundwater could be present in the AX20 excavation at any
time, or if surface runoff could fill the excavation at any time, resulting in
a "bathtub" effect.
• If you have questions about the need for antiflotation flanges, contact your
Designer or a qualified engineer.

Installation Steps
Step 16. Backfill Installation
n
Key Points:
• Do not alter the slope of pipes during backfilling. Brace them or place them
on compacted beds and then carefully fill around them.
• Before backfilling, make sure all lids are bolted down.
Step 16a: Finish backfilling the tank excavation if it isn't done yet. Follow the
manufacturer's instructions.
• For Orenco fiberglass tanks, see NIN-TNK-1, Fiberglass Tank Burial.
OIMPORTANT- Attaching the AX20 unit to an Orenco fiberglass tank
adds to the tank's buoyancy. In noncohesive soils, * this means a
concrete antiflotation collar has to be installed around the tank's mid -
seam. Contact your Dealer or a qualified engineer if you are unsure
whether a concrete collar is needed.
Step 16b: Backfill the pump basin if it hasn't been done yet.
• For Orenco PVC pump basins, see NIN-PB-1, PVC Basin Installation.
Step 16c: Backfill and compact around the AX20 unit in 12-in. (300-mm) lifts.
n
Key Points:
• Do not use native material to backfill if it is primarily sand; very soft or
highly expansive clay; or if it contains debris, large (> 3/4-in. or 19-mm)
rocks, sharp rocks, peat, or muck. In these cases, use s 1/4-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.
• In noncohesive soils" with high seasonal water tables, use 3/-inch
crushed rock as the backfill material.
• Do not backfill with sand.
Step 16d: Compact the fill thoroughly with a mechanical compactor.
nKey Points:
• The bottom of the AX2O lid should sit 2 inches (50 mm) above final
grade.
Step 16e: Close and secure the AX20 unit's lid.
Step 16f: Secure the access lids on the tank and pump basin (if used).
Step 16g: Before the system goes into use, contact the system's Service
Provider and complete the system start-up together per AIM-OM-ATX-1,
AdvanTex 0&M Manual: Start -Up and Routine Maintenance.
"As described in OSHA Standards (29 CFR, Part 1926, Subpart P, Appendix A), noncohesive soils
or granular soils include gravel, sand, or silt with little or no clay content. Granular soil cannot be
molded when moist and crumbles easily when dry. Cohesive soils include clayey silt, sandy clay,
silty clay, clay, and organic clay. Cohesive soil does not crumble, can be excavated with vertical
sideslopes, is hard to break up when dry, and when moist, can be rolled into threads without
crumbling. For example, if at least a 2-inch (51-mm) length of 1/8-inch (3-mm) thread can be
held on one end without tearing, the soil is cohesive.

Universal BiotubeO Pump Vaults
For use with Orenc& 4-inch (100-mm) Submersible Effluent Pumps
Applications
Orenco Biotube® Pump Vaults are used to filter effluent that is pumped
from septic tanks or separate dosing tanks in STEP systems and onsite
wastewater treatment systems. They remove two-thirds of suspended
solids, on average. Pump vaults house a Biotube effluent filter and one
or two Orenco high -head effluent pumps and can be used in single -
compartment septic tanks with flows up to 40 gpm (2.5 Usec). When
flows are greater than 40 gpm (2.5 Usec), a double -compartment sep-
tic tank or separate dosing tank is recommended.

General
The Orenco Biotube Pump Vault includes a molded polyethylene hous-
ing with an internal Biotube filter cartridge constructed of polypropylene
and PVC. Schedule 80 PVC support pipes are included to suspend the
vault in a tank opening. "Earless" 68-inch (1727-mm) vaults, which rest
on the bottom of the tank instead of on support pipes, are also available.
The filter cartridge can be removed without pulling the pump or the vault.
Effluent enters through inlet holes around the perimeter of the Biotube
vault and flows through the Biotubes to the external flow inducer. The
external flow inducer accommodates one or two pumps. Orenco Biotube
Pump Vaults are covered by U.S. patents #4,439,323 and 5,492,635.

Biotube� Pump Vault Installation
Biotube® PV and PVU Pump Vaults
There are two styles of Biotube° pump vaults, the PV-Style and the PVU-style
PV-style pump vaults come with support pipes. PVU—style pump vaults can be
configured in two ways:
Standard — Placed in the tank opening, resting on PVC support pipes.
Earless — Placed in the tank opening, resting on the bottom of the tank.
Step 1: Prep Vault for Installation
Step 1a: Detach and remove the float switch assembly from the float bracket.
Step 1 b: Remove any loose items from the vault.
Step 1c: Measure the tank opening diameter.
• PV-s le: minimum diameter is 16 in. (406 mm).
• PVU-style: minimum diameter is 19 in. (483 mm).
Step 1 d: For a standard PVU-style vault, check the diameter of the access riser.
• If the access riser's diameter is 30 in. (762 mm), measure the support pipes.
• If the support pipes aren't 24 in. long (600-mm), replace them with 1-in.
diameter (25-mm) Schedule 80 PVC pipes that are 24-in. long (600-mm) .
Step 1 e: Fully seat the Biotube° filter into the pump vault.
Step 2: Lower Vault into Position
Step 2a: Lower the vault into position.
• If the tank is full of liquid, fill the vault with water from a hose to help sink
the vault and prevent material from entering it through the inlet holes.
Step 2b: Make sure the vault is fully seated.
• "Standard" vaults sit in the tank opening; support pipes rest on the tank opening.
• "Earless" vaults sit in the tank opening; vault bottom rests on the tank bottom.
Step 2c: Reattach the float assembly after the vault is installed.
• Use NIN-MF-1, Float Switch Assembly Installation Instructions.
Step 2d: Position the vault in the riser to avoid interfering with plumbing or wiring.
• The penetration for the pump discharge in the access riser wall will deter-
mine the overall position of the vault.
Step 3: Install Handle Extension, if Necessary
If necessary, install an extension on the filter cartridge handle to bring it to within
6 inches (150 mm) below the top of the riser.
Step 3a: Measure and cut an appropriate length of 1-inch (25-mm) PVC pipe.
Step 3b: Use PVC cement to glue the extension into the cartridge handle's tee.

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 Usec) 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.

Discharge Assemblies
Applications
Orenco Discharge Assemblies are used to convey effluent from a
pump to the exterior of a riser or pump basin. They come in the fol-
lowing configurations:
• High head, for use with submersible turbine pumps
• Low head, for use with common effluent pumps
• Drainback, for use with shallowly buried tanks and transport lines in
cold climates
• Two additional applications are available:
• The cold weather kit coupled with a high -head discharge assembly
is intended for use with deeply buried tanks and transport lines in
cold weather
• The external flex extension is recommended for installations where
tank settling may occur to avoid line breakage during settling.
High head style shown with optional quick -disconnect
General
Orenco Discharge Assemblies are corrosion -resistant and adjustable
for a proper fit. Discharge assemblies are composed of PVC valves
and flexible hose that simplify installation and maintenance. The flex-
ible hose damps vibrations from the pump and allows for easy instal-
lation. Cam -style quick -disconnect fittings are available on all configu-
rations. All parts are either solvent welded or threaded and sealed with
Teflon® paste.
Teflon® is a registered trademark of DuPont.

to provide the best access to key components.
Step 4b: If necessary, make adjustments to the stem length.
• To cut the stem ...
Remove the pump and stem from the vault or flow inducer.
Cut the stem off at the mark.
Deburr the cut on the stem.
• To add length to the stem ...
Cut a section of pipe equal to the additional necessary distance for an
easy -to -service installation.
Deburr the cuts on the pipe section.
-- Glue the section to the stem with an appropriately sized pipe coupling.
Step 4c: Dry fit the stem to the rest of the discharge assembly.
Step 4d: If the pump and stem have been removed, lower the pump and stem
back into the pump vault's flow inducer compartment or into the flow inducer.
IMPORTANT- DO NOT lower the pump by the cord! This can damage the pump!
Step 5: Reassemble Discharge Assembly
Step 5a: Reconnect the discharge assembly.
• Field -cut type assemblies: glue the stem to the rest of the discharge
assembly at the first pipe joint above the top of the stem.
• Non -field -cut type assemblies: reconnect the stem and discharge assem-
bly at the first union above the stem.
Step 5b: Check and tighten all of the fittings on the discharge assembly.

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

The "On" and "Off" positions shown describe normally open float switches.
"On and "Off" positions are reversed for normally closed float switches.
General
All models except "J" are UL listed and GSA certified for use in water
or sewage; "J" switches are a GSA -certified direct alternative to "P"
switches. Non -mercury float switches (models B, C, J, N, and P) are
used where components containing mercury are prohibited.
Float switches are typically ordered in assemblies that include one or
more switches mounted on a 1 in PVC float stem. ABS float collars are
used to provide secure mounting that is easily adjustable.
Normally -open "P" float switches have a blue cap for easy
identification; normally -closed "N" float switches have a red cap.

Notes
'State: normally open or normally closed
Float switches have an internal contact. The terms "normally open" (N/0) and "normally closed" (WC) refer to the default state of the float switch contact. The default state refers to the contact positions in the
float switch when it is resting (down). A normally open float switch has an open contact (off) in the down position, and a normally closed float switch has a closed contact (on) in the down position. Different panel
functions require different types of float switches. Most applications require float switches that are normally open. One notable exception is the redundant off and low-level alarm function that requires a normally
closed float switch, except with MVP and VCOM panels.
P IR (intrinsically safe relay)
Indicates that the float switch is approved for use with intrinsically safe, Class 1, Division I applications, where reliable float switch operation with very low current is required.
'Drawdown
Drawdown (in inches) refers to the difference in liquid level between a float switch's activation and deactivation points. Drawdown can be altered by adjusting the tether length of the float switch cord. When
selecting float switches, keep in mind that any float switch that can directly start and stop a pump (one that has no motor contactor in the control panel) should have a drawdown capability, to avoid rapid cycling
of the pump.
' Signal -rated or motor -rated
Every float switch has a maximum amount of current it can handle. Exceeding these limits may cause premature failure. Signal -rated or "control" float switches are used to activate pump control panels and
alarms. Only low -amperage signals pass through these switches, hence the switch is "signal -rated. "All Orenco panels that use motor contactors can use signal -rated float switches. In some systems, a float
switch is used to directly start and stop a pump. In this application, the current running the pump passes through the switch as well, so the switch must be "motor -rated. "In most instances, a motor -rated float
switch can be used as a signal -rated float switch.

Float Switch Settings and Adjustments
Before You Begin
Part 1 of these instructions provides basic information on how to make initial float switch settings in the absence of guidance from site
plans, specifications, or applicable regulations regarding dosing, surge, and reserve volumes. These instructions are specific to pump vaults
and tanks of 1000gal (3758L) or greater volume, both single -compartment and two -compartment with shared liquid levels.
Part 2 of these instructions explains how to physically adjust the position of float switches on an Orenco float switch assembly. For
information on float switch settings and adjustments for AdvanTex° systems ("recirc" float switch settings), see NIN-ATX-DA-1, Float Switch
and RSV Settinas for Residential AdvanTex Svstems Instructions.
All product and performance assertions are based on proper design, installation, operation, and maintenance according to
Orenco's current published documentation.
Part 1, Guidelines for Initial Float Switch Settings
Float switch settings are the vertical distances from a common point of
reference on the tank's outside top to the set screw on the collar of individual
float switches. They are used to control alarms and pump operations. Float
switch settings are typically based on the needed or required volumes for the
corresponding functions operated by the control panel, such as initiating a
pumping event, engaging a timer, or triggering an alarm.
In the absence of guidance from site plans, specifications, or applicable
regulations. Orenco recommends the following initial float switch settings for
the systems listed in these instructions. Once you've determined the dose volume
or timer settings, it is important to assess the necessary volumes between the
float switches and adjust them accordingly.
Single -Pump (Simplex) Systems, Demand -Dose
O High -Level Alarm: Set at the same elevation as the tank inlet's invert.
© Pump On or Pump On/Off: Set 2in (51 mm) below the High -Level Alarm.
© Pump Off (if used): Set 2%2in (64mm) below the switch above it.
• Set this switch at least 5in (127mm) above the top of the filter cartridge if a
Redundant Off/Low-Level Alarm (13/0) is used. If an R/O float switch is not
used, set this switch at least 31n (76mm) above the top of the filter cartridge.
0 Redundant Off/Low-Level Alarm (if used): Set at least 2in (51 mm)
below the switch above it.
• Set this switch at least 3in (76mm) above the top of the filter cartridge.
• Make sure this float switch is above the pump's minimum liquid level
Single -Pump (Simplex) Systems, Timed -Dose
O High -Level Alarm or High -Level Alarm/Timer Override: Set at the same
elevation as the tank inlet's invert.

Measure the distance between
the top of the pump vault and
the top of the tank.
Two -Pump (Duplex) Systems, Timed -Dose, cont.
O Timer On/Off: Set at the distance below the override float switch that
equals the average daily flow for the system.
• Determine the average day flow for the system.
• Determine the gallons per inch (liters per millimeter) for the tank or basin.
• Divide the average daily flow by gallons per inch or liters per millimeter of
the tank chamber or basin to determine the necessary distance from the
Timer On/Off to the float switch above it.
• Set this switch at least 4%2in (114mm) above the top of the filter cartridge if
a Redundant Off/Low-Level Alarm (R/0) is used. If an R/O float switch is not
used, set this switch at least 3in (76mm) above the top of the filter cartridge.
© Redundant Off/Low-Level Alarm (in 4-switch systems): Set 2%2in
(64mm) below the switch above it.
• Set this switch at least 3in (76mm) above the top of the filter cartridge.
• Make sure this float switch is above the pump's minimum liquid level.
Part 2. Adjusting Float Switch Settings
Step 1. Check Float Switch Assembly Mi
Check the assembly against the system's wiring diagram (located in the control
panel).
• If you can't locate the wiring diagram, contact Orenco for a replacement.
• For information on 3-pump or 4-pump systems, contact your distributor
or Orenco.
Step 2. Verify Float Switch Settings i-w
Step 2a: Measure the distance between the top of the pump vault and the top
of the tank. Note this distance for use in the following steps.
• Use the top of the tank as the common reference point for setting float
switches.
Step 2b: Starting at the top of the pump vault, measure down along the stem
of the float switch assembly the same distance measured in the previous step.
Step 2c: Mark that distance on the float switch assembly stem.
• If measured and marked correctly, this mark should be level with the
outside top of the tank, and you can use it to measure float switch
settings with the float switch assembly removed.

Step 2. Verify Float Switch Settings, cont.
Step 2d: Remove the float switch assembly from the bracket.
Step 2e: Use the plans/specifications or applicable regulations and the
reference mark on the stem to make sure the float switches are set correctly.
• If the settings don't match the plans, specifications, or applicable regulations,
adjust the settings accordingly.
• If there are no plans, specifications, or applicable regulations, use the general
guidelines in this document to determine initial float switch settings for the
system.
• For further assistance, call your distributor or Orenco.
Step 3. Adjust Float Switch Settings
Step 3a: Loosen the set screw(s) on the float switch collar(s).
• Don't back the set screws completely out of the float switch collars.
Step 3b: Adjust the float switch collar(s) vertically to match the settings
provided on the plans or in applicable regulations.
• For existing systems, vertically adjust the collar as necessary to meet
discharge volume needs as described in the plans/specifications or
applicable regulations.
Step 3c: Check for vertical and horizontal clearance between the float switches
and between the float switches and the walls of the vault or basin.
• Move each float switch through its range of vertical motion.
• The float switches shouldn't interfere with one another during this check.
Step 3d: If the float switches interfere with another, adjust the collar horizontally
until the float switch is clear of the float switch(es) above or below it.
Step 3e: When the float switch(es) are adjusted and have vertical and horizontal
clearance, tighten the set screw(s).
Step 3f: Reinstall the float switch assembly back into the float switch bracket
and use the reference mark to set the float switch assembly at the correct
distance from the outside top of the tank.
Make sure that the walls of the vault or basin don't interfere with the
movements of the float switches. If they do, remove the float switches, and
readjust their horizontal clearances.
