1 INTRODUCTION
1.01 Background
Carolina Water Service Inc. of NC, Inc. owns and operates two wastewater treatment
plants that serve the Connestee Falls development located in Transylvania County just
south of the Town of Brevard and east of the Town of Rosman. The plants are located
in different drainage basins but the same river basin (French Broad) and have separate
service areas of the Connestee Falls Development. Carolina Water Service Inc. of NC,
Inc. is seeking to replace the Connestee Falls Wastewater Treatment Plant No. 1. See
Figure 1 for location map
The Connestee Falls WWTP No. 1 was initially completed in the early 1970's and has
been in continuous operation since completion of the plant. The current NPDES Permit
NC 0024295, included as Appendix A, was issued on January 26, 2016 and expires
September 30, 2020. A permit modification was requested August of 2017 to allow for
expansion to 360,000 gpd as an intermediate step between 300,000 gpd and the
460,000 expansion currently allowed under the permit that was issued January 2016.
The draft permit is attached as Appendix B. The system receives only domestic
wastewaters. The rated capacity of the existing plant is 300,000 gpd.
Under the original plans for the Connestee Falls Development, the intent for the
wastewater treatment facilities was to construct them in phases as actual home
construction occurred. Thus, collection sewers were installed throughout the developed
street network while only built upon lots were connected. Sewer collection facilities exist
and are available for connection of platted, un -built upon lots and there remains an
obligation by Carolina Water Service Inc. of NC to serve these lots.
Given the age of the existing plant and associated facilities, Carolina Water Service Inc.
of NC (CWSNC) retained professional engineering services to investigate the structural
integrity of the existing poured in place concrete tankage comprising the treatment
process. The results of this investigation indicate serious deterioration of the concrete
to the extent that reclamation/reconstruction is not feasible. This realization has led to
a decision to replace the existing treatment units with new facilities.
1.02 Purpose of Report
Carolina Water Service has elected to replace the existing Connestee Falls Wastewater
Treatment Plant #1 with a Sequencing Batch Reactor (SBR) having a rated capacity of
360,000 gpd and to further add as beneficial improvements, an automatically cleaned
fine screen with vertical lifting, dewatering and compaction of screenings, cloth media
filtration, and UV disinfection systems.
The cloth media filters and UV disinfection systems will be installed in parallel treatment
trains with each UV unit and each filter sized to treat effluent at the peak flow of 0.90
LDI PN: 1014381 N:\_2014\1014381\Docs\Calcs\14381-ER and Calcs-Rev.docx pg. 4

MGD. Automatic controls and valves will be provided to switch flow between
disinfection units in case of failure.
The vertical screen will be installed in an existing channel located at the existing influent
pump station.
Additionally, the lift station pumps will be replaced to account for the increased static
head condition required by the proposed SBR. Two pumps with VFD controls are
proposed. Each of the pumps will be sized for the peak flow and total dynamic head
condition so that one pump provides backup for the other. During normal operation,
the duty and standby pumps will be alternated so that each pump is in service
approximately 50% of the time.
On behalf of Carolina Water Service Inc. of NC, LandDesign is filing an application to
NCDEQ — Division of Water Resources for an Authorization to Construct modifications
to the Connestee Falls Wastewater Treatment Plant #1 (NPDES Permit # NC0024295)
located at 5999 Greenville Highway Brevard, NC in Transylvania County.

2 BASIS OF DESIGN
2.01 Development Summary
The Connestee Falls community now has 1,008 connections and is provided water and
sewer services by Carolina Water Service Inc., of NC by two wastewater treatment
plants. Connestee Falls WWTP No. 1 serves the majority of the development.
The development consists predominately of single family detached residential homes,
with an additional 21 duplex buildings (2 dwelling units/buildings) and 32 condos as well
as the clubhouse serving the Connestee Falls Golf Club. Table 1 presents a service
area summary.
Table 1 - Service Area Summary
2.02 Proiected Flows
A unit flow reduction request was submitted to NCDEQ in December of 2014 and
approved January 2015. Based on the approved design flow rate of 85 gallons per day
per bedroom (300 gpd / 3.5 bdr) the required capacity of WWTP #1 would be 460,000
per day.
The current and anticipated near term flow rates do not support the construction of a
plant with a rated capacity of 0.46 MGD, and a 0.30 MGD plant would likely need to be
expanded soon after completion. CWSNC is therefore proposing to construct a 0.36
MGD plant with future expansion to 0.46 MGD.

CALCULATIONS
3.01 Automatically Cleaned Fine Screen
One (1) Rotamat RoK 4 Vertical Screen 300 from Huber Technology, Inc. is proposed
to be installed upstream of the existing bar screen and flow monitoring flume in an
existing channel at the existing lift station. A custom fabricated stainless steel channel
will be provided so that any emergency bypass flow from the vertical screen will be
directed to the existing bar screen. The proposed screen has been sized for the peak
flow at the final treatment plant build out of 460,000 gpd to ensure that the equipment
does not need to be replaced when expansion is required in the future. Table 2 below
is a summary of the screen design:

3.02 Lift Station Pumps
The existing lift station pumps will require upgrading due to the increased static head
created by the proposed SBR tank. The replacement pumps will be fitted to the existing
piping in the lift station pump room.
Two pumps with VFD controls are proposed. Using the VFD's along with a pump
controller allows the speed of the pump(s) to match the flow coming into the lift station.
Each of the pumps will be sized for the peak flow and total dynamic head condition so
that one pump provides backup for the other. During normal operation, the duty and
standby pumps will be alternated so that each pump is in service approximately 50% of
the time. When there is a need for future expansion, a third identical pump will be
added to accommodate the additional flow. Any two of the pumps would meet the peak
demand with the third being back-up. The head loss calculations are included as Figure
3. The pump curves and pump cut sheets are included in Appendix C. The summary

3.03 Sequencing Batch Reactor Reliability
The proposed SBR system utilizes the activated sludge process, which completes all
unit process steps within the same reactor. The tanks operate together, filling in
alternating sequence where influent is fed first to one tank, and then to the next, and so
on. Influent is never automatically fed to multiples tanks at the same time.
Each reactor cycles through 5 steps per batch as shown in the image below:

--.—r1,-SETTLE
The fill phase is divide into anoxic fill where influent enters the reactor in the absence
of oxygen and aerated fill where the aeration system is turned on. When the react phase
is initiated in one reactor, influent flow is diverted to the other reactor. At the end of the
react step the biomass is allowed to settle in quiescent conditions. Following the
settlement step an automatic valve opens and treated effluent is decanted from
approximately 18" below the surface and is directed to the post equalization tank. When
decant has completed the basin enters the idle step and will wait to receive influent
when the second reactor enters the react step.
The rated capacity of the plant is 360,000 gpd. However, the SBR has been designed
using an influent flow rate of 1.5 x the proposed capacity (360,000 x 1.5 = 540,000 gpd)
LDI PN: 1014381 N:\_2014\1014381\Docs\Calcs\14381-ER and Calcs-Rev.docx Pg. 9

to account for the hourly peak flow fluctuations. The factor of 1.5 is based on a
comparison of the historical average daily and maximum daily flows over the past 3
years. It was determined that the maximum daily flow did not exceed the average daily
flow by more than 1.5 times.
At influent flow rates at or below 540,000 gpd, there will be no shortening of the cycles
described above and the treated effluent will meet the design effluent limits described
in Section 2.06. Above 540,000 gpd the cycle timing is automatically adjusted to
maximize treated effluent quality. Additionally, the SBR can operate at the peak
hydraulic flow of 900,000 for an indefinite period of time with reduced effluent quality.
In the event that a reactor needs to be removed from service for maintenance, a single
reactor can operate in continuous flow mode.
The proposed design limits the number of maintenance prone components that are
installed inside of the reactor tanks and all component are constructed from durable
materials to limit the possibility needing to take a reactor out of service. For example,
aeration and mixing within each reactor is performed using jet aeration so that there are
no bubble diffusers that will require replacement. Jet aeration requires no routine
maintenance and has a life expectancy in excess of 20 years with no reduction in
oxygen transfer efficiency due to wear of the jet aerators. Because there are no electro-
mechanical parts or membranes to maintain within the basin, all routine maintenance
may be performed outside of the basin. All electromechanical equipment, including
pumps, blowers, valves, and the control system to be located inside a building near the
tanks.

Subject: Issuance of NPDES Permit Renewal and Expansion
Permit No. NCO024295
Connestee Falls WWTP No. 1
Transylvania County
Facility Class II
Division personnel have reviewed and approved your application for renewal and expansion of the subject
permit. Accordingly, we are forwarding the attached NPDES discharge permit. This permit is issued
pursuant to the requirements of North Carolina General Statute 143-215.1 and Memorandum of
Agreement between North Carolina and the U.S. Environmental Protection Agency dated October 15,
2007 (or as subsequently amended).
No changes were made to the draft permit sent to you on December 2, 2015. The final permit
authorizes Transylvania Utilities Inc. to discharge wastewater from the Connestee Falls WWTP No. 1 to
French Broad River, a class B; Tr water in the French Broad River Basin. The permit includes discharge
limitations and/or monitoring for flow, BODS, ammonia nitrogen, total suspended solids (TSS), pH,.
temperature, total residual chlorine, fecal coliform, total nitrogen, and total phosphorus.
The North Carolina Wildlife Resources Commission (WRC) provided comments on Connestee
Falls WWTP No. I's draft permit, expressing concern over potential impacts from the expanded
wastewater discharge to downstream aquatic life.
• Specifically, WRC expressed concerns over the use of chlorine and its potential toxicity to
aquatic life. In response, DWR encourages the permittee to avoid overdosing during
chlorination with current facility. The proposed new facility (permitted flow of 0.46 MGD) is
designed to have UV disinfection and a backup chlorination/dechlorination system.
• WRC encouraged the permittee to implement measures to reduce ammonia -nitrogen in the
effluent due to the fact that peak effluent ammonia concentrations in the summer of 2014 and
2015 were 9.2 and 6.9 mg/L, respectively. DWR has discussed with the permittee the plant
operation during the summers of 2014 and 2015. The operation log sheets showed one of the
mechanical aerators was down for repair from Aug. 8 to Oct. 30 in 2014 which could have
potentially affected the effluent ammonia levels. However, no operation issues were found in
State of North Carolina I Environmental Quality I Water Resources
1617 Mail service Center I Raleigh, North Carolina 27699-1617
919 707 9000

Page 2 of 3
the summer of 2015. The permittee stated that the proposed new facility would have a better
consistency and compliance with its design.
• The use of additional treatment technologies to reduce endocrine disruptive compounds,
personal care products and pharmaceuticals was encouraged by the WRC. In response, DWR
will recommend that the facility continue to treat wastewater with the best available
technology. Currently, water quality standards or federal criteria have not been established
for these new substances, therefore DWR cannot establish limits/monitoring or require the
installation of additional treatment.
• WRC stated that if not already in place, a standby power system should be installed. DWR
has consulted with the permittee. Currently, the facility has a main lift station generator
which can power both the lift station and the primary mechanical aerators. However, it does
not power the whole plant. The proposed new facility will have a standby power
generator/system for the whole plant.
As identified previously, the renewal permit contains the following significant changes from
your current permit:
• Added a new paragraph on the Supplement to Permit Cover Sheet that the permittee is authorized to
construct and operate a 0.46 MGD facility after receiving an Authorization to Construct from the
Division and submission of an approved engineer's certification for construction.
• The requirement to begin reporting discharge monitoring data electronically using the NC DWR's
Electronic Discharge Monitoring Report (eDMR) internet application has been added to your NPDES
permit. [See Special Condition A.(3.)]
For information on eDMR, registering for eDMR and obtaining an eDMR user account, please visit the
following web page: http://portal.ncdenr.org/web/wq/admin/boglipu/edmr.
For information on EPA's proposed NPDES Electronic Reporting Rule, please visit the following web
site: http://www2.epa. ov/compliance/proposed-npdes-electronic-reporting rule.
The Division recognizes that the facility is currently submitting eDMRs. This requirement is being
inserted into all NPDES permits and should be considered a formality.
• Added a new Effluent Sheet, A. (2), for the proposed expansion to 0.46 MGD. DWR staff concurred
with the projected flow justification and engineering alternatives analysis conclusion that an expansion
at the current location with a direct discharge to surface water was the most environmentally sound
alternative from the reasonably cost-effective options (per 15A NCAC 2H.0105),

A (3) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
[G. S. 143 -215.1(b)]
Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and
specify that, if a state does not establish a system to receive such submittals, then permittees must submit DMRs
electronically to the Environmental Protection Agency (EPA). The Division anticipates that these regulations
will be adopted and is beginning implementation in late 2013.
NOTE: This special condition supplements or supersedes the following sections within Part II of this permit
(Standard Conditions for NPDES Permits):
• Section B. (11.) Signatory Requirements
• Section D. (2.)
• Section D. (6.)
• Section E. (5.)

Monitoring Reports
1. Reporting [Supersedes Section D. (2.) and Section E. (5.) (a)1
Beginning no later than 270 days from the effective date of this permit, the permittee shall begin reporting
discharge monitoring data electronically using the NC DWR's Electronic Discharge Monitoring Report
(eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each month and
submitted electronically using eDMR. The eDMR system allows permitted facilities to enter monitoring
data and submit DMRs electronically using the internet. Until such time that the state's eDMR application
is compliant with EPA's Cross -Media Electronic Reporting Regulation (CROMERR), permittees will be
required to submit all discharge monitoring data to the state electronically using eDMR and will be required
to complete the eDMR submission by printing, signing, and submitting one signed original and a copy of the
computer printed eDMR to the following address:
NC DEQ / DWR / Information Processing Unit
ATTENTION: Central Files/ eDMR
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility being
physically located in an area where less than 10 percent of the households have broadband access, then a
temporary waiver from the NPDES electronic reporting requirements may be granted and discharge
monitoring data may be submitted on paper DMR forins (MR 1, 1. 1, 2, 3) or alternative forms approved by
the Director. Duplicate signed copies shall be submitted to the mailing address above.
Requests for temporary waivers from the NPDES electronic reporting requirements must be submitted in
writing to the Division for written approval at least sixty (60) days prior to the date the facility would be
required under this permit to begin using eDMR. Temporary waivers shall be valid for twelve (12) months
and shall thereupon expire. At such time, DMRs shall be submitted electronically to the Division unless the
permittee re -applies for and is granted a new temporary waiver by the Division.
Information on eDMR and application for a temporary waiver from the NPDES electronic reporting
requirements is found on the following web page:
Part I, Page 5

Permit NC0024295
httn://aortal.nedenr.oriz/web/wo/admiri/boL/inu/edmr
Regardless of the submission method, the first DMR is due on the last day of the month following the
issuance of the permit or in the case of a new facility, on the last day of the month following the
commencement of discharge.
2. Signatory Requirements [Supplements Section B. (11.) (b) and supersedes Section B. (11.) (d)1
All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part II,
Section B. (11.)(a) or by a duly authorized representative of that person as described in Part H, Section B.
(11.)(b). A person, and not a position, must be delegated signatory authority for eDMR reporting purposes.
For eDMR submissions, the person signing and submitting the DMR must obtain an eDMR user account
and login credentials to access the eDMR system. For more information on North Carolina's eDMR
system, registering for eDMR and obtaining an eDMR user account, please visit the following web page:
http://portal.ncdenr.org/web/Wq/admin/bog/ipu/edmr
Certification. Any person submitting an electronic DMR using the state's eDMR system shall make the
following certification [40 CFR 122.22]. NO OTHER STATEMENTS OF CERTIFICATION WILL BE
ACCEPTED:
U cert, under penalty of law, that this document and all attachments were prepared under my direction or
supervision in accordance with a system designed to assure that qualified personnel properly gather and
evaluate the information submitted. Based on my inquiry of the person or persons who manage the system,
or those persons directly responsible for gathering the information, the information submitted is, to the best
of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for
submitting false information, including the possibility of fines and imprisonment for knowing violations. "
3. Records Retention [Supplements Section D. (6.)]
The permittee shall retain records of all Discharge Monitoring Reports, including eDMR submissions.
These records or copies shall be maintained for a period of at least 3 years from the date of the report. This
period may be extended by request of the Director at any time [40 CFR 122.41].

Samples are collected three times per week on three separate calendar days. These samples shall be representative of
the wastewater discharged during the sample period.
Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act (CWA), as amended, 33 USC 1251, et.
seq.
Annual Average
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case of fecal
coliform, the geometric mean of such discharges.
Arithmetic Mean
The summation of the individual values divided by the number of individual values.
Bypass
The known diversion of waste streams from any portion of a treatment facility including the collection system, which is
not a designed or established or operating mode for the facility.
Calendar Day

Calendar Quarter
One of the following distinct periods: January through March, April through June, July through September, and
October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 mL in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The
Director may designate the most appropriate method (specific number and size of aliquots necessary, the time interval
between grab samples, etc.) on a case-by-case basis. Samples may be collected manually or automatically. Composite
samples may be obtained by the following methods:
(1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24 hour period
of discharge and combined proportional to the rate of flow measured at the time of individual sample
collection, or
(3) Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period with
the time intervals between samples determined by a preset number of gallons passing the sampling point. Flow
measurement between sample intervals shall be determined by use of a flow recorder and totalizer, and the
preset gallon interval between sample collection fixed at no greater than 1/24 of the expected total daily flow at
the treatment system, or

Interference
Inhibition or disruption of the POTW treatment processes; operations; or its sludge process, use, or disposal which
causes or contributes to a violation of any requirement of the Pennittee's (or any satellite POTW's if different from the
Permittee) NPDES, collection system, or non -discharge permit or prevents sewage sludge use or disposal in
compliance with specified applicable State and Federal statutes, regulations, or permits. [15A NCAC 02H
.0903(b)(14)]
Pass Through
A discharge which exits the POTW into waters of the State in quantities or concentrations which, alone or with
discharges from other sources, causes a violation, including an increase in the magnitude or duration of a violation, of
the Permittee's (or any satellite POTW's, if different from the Permittee) NPDES, collection system, or non -discharge
permit. [15A NCAC 02H .0903(b)(23)]
Publicly Owned Treatment Works (POTW)
A treatment works as defined by Section 212 of the CWA, which is owned by a State or local government organization.
This definition includes any devices and systems used in the storage, treatment, recycling and reclamation of municipal

Permit NCO024295
A.(4.) ELECTRONIC REPORTING OF MONITORING REPORTS [G.S. 143-215.1(b)]
Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program
reports. The final NPDES Electronic Reporting Rule was adopted and became effective on December
21, 2015.
NOTE: This special condition supplements or supersedes the following sections within Part II of this
permit (Standard Conditions for NPDES Permits):
• Section B. (11.) Signatory Requirements
• Section D. (2.) Reporting
• Section D. (6.) Records Retention
• Section E. (5.) Monitoring Repots
1. Reporting Requirements [Supersedes Section D. (2.) and Section E. (5.) (a)1
The permittee shall report discharge monitoring data electronically using the NC DWR's Electronic
Discharge Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each month and
submitted electronically using eDMR. The eDMR system allows permitted facilities to enter
monitoring data and submit DMRs electronically using the internet. Until such time that the state's
eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation
(CROMERR), permittees will be required to submit all discharge monitoring data to the state
electronically using eDMR and will be required to complete the eDMR submission by printing,
signing, and submitting one signed original and a copy of the computer printed eDMR to the
following address:
NC DEQ / DWR / Water Quality Permitting Section
Attn: Central Files
1617 Mail Service Center
Raleigh, NC 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility
being physically located in an area where less than 10 percent of the households have broadband
access, then a temporary waiver from the NPDES electronic reporting requirements may be granted
and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1. 1, 2, 3) or alternative
forms approved by the Director. Duplicate signed copies shall be submitted to the mailing address
above. See "How to Request a Waiver from Electronic Reporting" section below.
Regardless of the submission method, the first DMR is due on the last day of the month following
the issuance of the permit or in the case of a new facility, on the last day of the month following the
commencement of discharge.
Starting on December 21, 2020, the permittee must electronically report the following compliance
monitoring data and reports, when applicable:
Page 6 of 9

Permit NC0024295
• Sewer Overflow/Bypass Event Reports;
• Pretreatment Program Annual Reports; and
• Clean Water Act (CWA) Section 316(b) Annual Reports.
The permittee may seek an electronic reporting waiver from the Division (see "How to Request a
Waiver from Electronic Reporting" section below).
2. Electronic Submissions
In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial recipient at the time
of each electronic submission. The permittee should use the EPA's website resources to identify the
initial recipient for the electronic submission.
Initial recipient of electronic NPDES information from NPDES-regulated facilities means the entity
(EPA or the state authorized by EPA to implement the NPDES program) that is the designated entity
for receiving electronic NPDES data [see 40 CFR 127.2(b)].
EPA plans to establish a website that will also link to the appropriate electronic reporting tool for
each type of electronic submission and for each state. Instructions on how to access and use the
appropriate electronic reporting tool will be available as well. Information on EPA's NPDES
Electronic Reporting Rule is found at:
hllps•//www federalre ig ster.gov/documents/2015/10/22/2015-24954/national-pollutant-discharge-
elimination-system-rides-electronic-reporting-rule.
Electronic submissions must start by the dates listed in the "Reporting Requirements" section above.
3. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an
electronic reporting waiver, a permittee must first submit an electronic reporting waiver request to
the Division. Requests for temporary electronic reporting waivers must be submitted in writing to
the Division for written approval at least sixty (60) days prior to the date the facility would be
required under this permit to begin submitting monitoring data and reports. The duration of a
temporary waiver shall not exceed five (5) years and shall thereupon expire. At such time, monitoring
data and reports shall be submitted electronically to the Division unless the Permittee re -applies for
and is granted a new temporary electronic reporting waiver by the Division. Approved electronic
reporting waivers are not transferrable. Only permittees with an approved reporting waiver request
may submit monitoring data and reports on paper to the Division for the period that the approved
reporting waiver request is effective.
Information on eDMR and the application for a temporary electronic reporting waiver are found on
the following web page:
http://deq.nc.gov/about/divisions/water-resources/edmr
Page 7 of 9

Permit NC0024295
4. Signatory Requirements [Supplements Section B. (11.) (b) and Supersedes Section B. (11.) (d)1
All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part
II, Section B. (11.)(a) or by a duly authorized representative of that person as described in Part II,
Section B. (I 1.)(b). A person, and not a position, must be delegated signatory authority for eDMR
reporting purposes.
For eDMR submissions, the person signing and submitting the DMR must obtain an eDMR user
account and login credentials to access the eDMR system. For more information on North Carolina's
eDMR system, registering for eDMR and obtaining an eDMR user account, please visit the following
web page:
htt-o:Hdeg.ne.gov/about/divisions/water-resources/edmr
Certification. Any person submitting an electronic DMR using the state's eDMR system shall make
the following certification [40 CFR 122.22]. NO OTHER STATEMENTS OF CERTIFICATION
WILL BE ACCEPTED:
"I certify, under penalty of law, that this document and all attachments were prepared under my
direction or supervision in accordance with a system designed to assure that qualified personnel
properly gather and evaluate the information submitted. Based on my inquiry of the person or
persons who manage the system, or those persons directly responsible for gathering the information,
the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I
am aware that there are significant penalties for submitting false information, including the
possibility of fines and imprisonment for knowing violations. "
5. Records Retention [Supplements Section D. (6.)1
The permittee shall retain records of all Discharge Monitoring Reports, including eDMR
submissions. These records or copies shall be maintained for a period of at least three (3) years from
the date of the report. This period may be extended by request of the Director at any time [40 CFR
122.41].

The SE1/SL1 pumps, 9 - 30 kW, are a range of channel impeller pumps specifically designed for pumping
sewage and wastewater in a wide range of municipal and industrial applications.
The SE1/SL1 pump has a S -tube channel impeller with 3.35 in free passage and is designed for
applications such as:
• raw water intake
• wastewater treatment plants
• municipal pumping stations
• public buildings
• blocks of apartments
• industries
• garages
• underground car parks
• car wash areas
• restaurants and hotels.
The pumps are suitable for both temporary and permanent installation. The lifting bracket fitted on the
pumps facilitates easy transportation to as well as installation at the installation site.
The pumps are made of resistant materials, such as cast iron and stainless steel. These materials ensure
proper operation.
The pump is very service friendly with features like double shaft seal in the unique cartridge design and
cable entry connector.
The cartridge shaft seal allows change of shaft seal very quickly in the field without any special tools
whereas the cable entry connector allows the cable to be dismantled without removing the motor top.
These smart design features eliminate the risk of faulty installation.
The pump comes with a high efficient Grundfos Blueflux motor.
The SL1 version is for submersible installation either free-standing or on an auto -coupling system
whereas the SE1 pump can be used for dry -installation as either free-standing, on autocoupling or
vertically/horizontally installed on baseplate.
