CONDITION ASSESSMENT REPORT
Grassy Branch Collection System
Union County Water
June 2022
INTRODUCTION
The Grassy Branch Sewer Collection System has been a concern for Union County Water
for a number of years due to the Grassy Branch Water Reclamation Facility (WRF)
frequently exceeding its capacity. Dating back to 2016, the County has conducted several
flow monitoring studies to quantify the amount of infiltration and inflow (1-1) entering the
system during periods of wet weather. It has also performed several phases of sewer
system evaluation activities including smoke testing, manhole inspections and iTracker
micro -detection studies to identify the exact sources of 1-I. It has subsequently repaired
any of these defects that were identified.
At the present time, the County is confident that the problem is simply a lack of capacity
since the average dry weather daily flow rate is very close to the treatment capacity of the
Grassy Branch WRF. Even minor amounts of 1-1 will cause the WRF to exceed its capacity
and potentially result in sanitary sewer overflows (SSOs) in the system. Despite this, the
County decided to perform CCTV inspections of all sewer mains and laterals within the
Grassy Branch collection system to identify any defects that could potentially allow 1-1 to
enter the system.
This report presents the findings of these CCTV inspections. The information gathered
during the study has been used to identify specific defects within the system and develop
repair/rehabilitation recommendations with cost estimates in order to assist the County
with reducing I/1 into the collection system.
II. GRASSY BRANCH COLLECTION SYSTEM INVENTORY
The Grassy Branch collection system ends at the WRF just north of Old Fish Road, runs
parallel to Grassy Branch, crosses Unionville Road and Sikes Mill Road to Piedmont
High School and Middle School. (This system also receives sewer via a force main from
Unionville Elementary School) A "Sewer Main Priority Rating Map' is included in
Appendix A and shows the full extent of the gravity collection system and study area.
This collection system includes approximately 30,868 linear feet of gravity sewer. The
mains are a mix of polyvinyl chloride (PVC) and ductile iron pipe (DIP). Table 1, below,
lists the footage of each diameter and material of pipe found in the study area.

Ill. RESULTS OF FIELD INVESTIGATIONS
A. Cleaning and Internal CCTV Inspection
All lines were cleaned using a high -velocity jet / vacuum truck in order to remove debris
and provide an unobstructed view of the pipe surface. After cleaning, the lines were then
visually inspected by means of a closed-circuit television (CCTV) system, which includes
a self-propelled tractor and camera unit. The camera is coupled with an inspection system
containing both digital video recorders, footage counter and a laptop equipped with IT
Pipes video inspection reporting software. Service laterals were inspected using a special
system that "launches" a smaller camera up into the lateral from the main.
For each mainline section or lateral, an inspection log was prepared showing the location
of any structural defects, offset or separated joints, points of infiltration, roots, etc. The log
also shows the location of all service connections and upstream and downstream manhole
numbers. The complete inspection was also recorded on videotape and captured digitally
on MPEG files. A copy of the inspection logs is contained in Appendix B. Digital videos
and digital inspection logs for each line segment are included on Appendix D (thumb
drive).
Once all the lines were cleaned and inspected, the next step was to evaluate each line
and prioritize the lines according to condition severity. Based on our evaluations, each
defect was assigned a priority rating from 1 to 5. The priority rating system uses the
NASSCO Pipeline Assessment and Certification Program (PACP) and Lateral
Assessment Certification Program (LACP) methodology described below.
• Grade 5 — Defects require immediate attention. Pipe has failed or will
likely fail within the next five years
• Grade 4 — Severe defects that will become Grade 5 within the
foreseeable future.
• Grade 3 — Moderate defects that will continue to deteriorate
• Grade 2 — Defects that have not begun to deteriorate.
• Grade 1 — Minor defects
NASSCO recognizes two families of defects: structural defects and operation and
maintenance (O&M) defects. Structural defects are various types of defects within the
structure of the pipe including cracks, fractures, broken pipe, collapsed pipe, offset or
separated joints, surface damage from expose to hydrogen sulfide gas, etc. Operation
and maintenance defects include deposits (grease, sand), roots, infiltration, obstructions,
etc. that affect the system's ability to operate properly.
NASSCO also assigns each structural and O&M defect with a grade rating corresponding
to the severity of the defect (5 the most severe and 1 the least severe). A grade score is
Page 2 of 14
Grassy Branch — Condition Assessment Report
Union County Water

calculated by multiplying the grade rating by the number of occurrences of that grade
identified throughout the pipe. The grade scores are summed in their appropriate families
(structural and O&M) to calculate the structural defect rating and O&M defect rating. The
overall rating is the sum of structural and O&M defect ratings. Each pipe is also assigned
a quick rating, which is a four -digit number showing the number of occurrences for the
two highest severity grades occurring in that pipe (the number is displayed with the grade
rating first followed by the number of occurrences). For example, if the pipe inspected
has two grade 5 defects and six grade 4 defects the quick rating would be 5246.
Hydrostructures assigns a priority ranking based on the severity of the worst defect
contained in the line. Therefore, a line containing a structural collapse (grade 5) would
be scored as a priority 5. The results of the priority rating process are provided in the
table below.
Zero (0) priority 5, one (1) priority 4, thirty-four (34) priority 3, one (1) priority 2, and ninety-
one (91) priority 1 mainline pipe sections were identified in the collection system (Table
2 below). A "Sewer Main Priority Rating Map" is provided in Appendix A and shows the
location and priority rating for all mainlines inspected as part of this evaluation. CCTV
logs for all pipe segments inspected on the system are included in Appendix B.

Structural Defects
Very few structural defects were identified in the mainline sections. Two sags were identified that
do not require repair. The remaining pipe was found to be in good condition.
Operation and Maintenance Defects and Infiltration
O&M defects include debris, sand, rocks, grease, infiltration, etc. The sewer cleaning removed
most settled / attached debris and deposits. There were very few maintenance defects and only
one mainline joint with infiltration that needs a 4' sectional liner. This joint, between DIP and PVC,
had a small dripper. See photo below.
There was only one service lateral that needs a lateral seal for infiltration that is coming between
the service lateral and the mainline section. See photo below.

B. Service Lateral CCTV Inspection
In addition to the PACP inspection of all pipe segments, each service lateral was
inspected and prioritized according to the Lateral Assessment Certification Program
(LACP). Based on our evaluations, each defect was assigned a priority rating from 1 to
5. The priority rating system uses the NASSCO Pipeline Assessment and Certification
Program (PACP) methodology described above.
A total of 132 service laterals were located in the collection system at the time of the
project and all except 3 were inspected. All were PVC and 4-inches in _diameter. A few
had grease, sags, or offset joints, but only one requires repair. Each has been assigned
a priority rating and the summary table is provided below. Zero (0) priority 5, one (1)
priority 4, one (1) priority 3, eleven (11) priority 2, and one hundred sixteen (116) priority
1 service laterals were identified in the collection system (Table 2 below). A "Sewer Main
Priority Rating Map" is provided in Appendix A and shows the location for all service
laterals inspected as part of this evaluation. Inspection logs for all the service laterals are
included in Appendix C.

IV. ALTERNATIVES EVALUATION
Several methods and technologies are available for the rehabilitation of sewer mains and
service laterals. This section discusses the available and most commonly recommended
/ implemented rehabilitation methods.
A. Manhole Rehabilitation and Repairs
1. Pipe Connection Infiltration
Pipe connections between the manhole wall and the influent and effluent piping
are sometimes found to be sources of infiltration and root intrusion. These
connections may lack a boot (typically older brick manholes) and not be adequately
grouted or the boot was not properly seated and tightened around the pipe during
installation. Infiltration is especially prevalent in deeper manholes, where the
hydrostatic pressure from high groundwater levels can cause significant leaks
through relatively small cracks and holes.
We recommend that leaking pipe connections be sealed by injecting chemical
grout pumped through drilled injection ports into the crack or void from the inside
of the manhole. The grout will penetrate to the exterior of the manhole, where it
will fill any voids and seal the leak from the outside. After the void has been filled
with chemical grout, cementitious grout should be used to seal the pipe connection
from the inside of the manhole.
Estimated Cost: $500.00 per Pipe Connection.
B. Sewer Main Rehabilitation and Repairs
1. Open -Cut Point Repairs
A point repair consists simply of excavating down to a damaged section of pipe
and replacing the damaged section with new pipe. It is used when damage is
isolated to one particular area of the pipe, generally less than twenty feet in length.
It is also used to repair pipe collapses, sags, and/or offset joints prior to manhole -
to -manhole trenchless rehabilitation by CIPP. It can be very disruptive to the
surrounding area, especially if the pipe is deep or underneath pavement. It can
also be extremely expensive depending upon the location and/or depth of the
repair.
Estimated Cost: 8" —12" = $12,500
15" —18" = $17,500
*Includes bypass pumping, assumes DIP
2. Internal CIPP Sectional Liner (CIPP Spot Repair)
Sectional cured -in -place spot repairs are ideal for patching holes and other
isolated, non -deformed structural defects. Spot repair patches can be used for
infiltration control when hydrophilic 0-rings or caulk is used between the host pipe
Page 11 of 14
Grassy Branch — Condition Assessment Report
Union County Water

and ends of the repair patch. Most manufactures have repair patches available
up to 42-inches and lengths of 2, 4,, and 8-feet are common. Patches are
fiberglass with epoxy resin or typical felt with vinylester resin.
Spot repairs are installed with a flow through bladder. The patch is secured to
the inflatable bladder, pulled into place, the bladder pressurized to form the patch
tightly to the pipe surface and allowed to cure ambiently. Because the bladder is
flow through, little or no flow control is required during installation
Estimated Cost: 8" —12" _ $5,000
16" —18" _ $9,500
C. Service Lateral Rehabilitation and Repairs
The following section discusses service lateral rehabilitation methods including
connecting service laterals to the main line. Cost estimates for each method are
provided based on similar rehabilitation projects.
1. Open -Cut Replacement
This method of repair consists of excavating the defective service lateral and
replacing it with a new lateral within the same trench. This method is the most
cost effective to rehabilitate shallow service laterals. in low traffic areas. Although
it obviously requires more excavation, it is the most frequently recommended
method for service rehabilitation. Service lateral replacement is only performed
from the sewer main to the right-of-way (location of the cleanout).
Estimated Cost: $100 per linear foot of service lateral
(if the replacement of the lateral includes the replacement or installation of a
cleanout and reconnection to the main line, the total cost is usually an additional
$2,000 or $3,000.)
2. CIPP Lateral Seal
Full Wrap Lateral Seal rehabilitation is a trenchless service connection
rehabilitation method used to seal leaking service connections and restore
structurally integrity. Full wrap lateral seals are recommended when conflicts or
depth increase the difficulty and cost of excavation. A full wrap later seal includes
a polyester felt tube with a sewn flange that covers up to 16-inches of the mainline
in a full wrap. The use of hydrophilic sealants and silicate resins applied to the
backside of the full warp connection enhances the watertight seal. Typically, this
wrap includes 2-feet of lateral liner to extend up into the service lateral. Ambient
cure polyester or vinylester resins are used. Diameters of 4-inch and 6-inch
service lateral rehabilitation are possible with 8-inch to 24-inch mainline wraps.
During installation, the mainline must be cleaned and free of all debris. Roots and
other debris are removed from the lateral connection. The full wrap lateral seal is
loaded on a silicone bladder lateral train and inserted through the downstream
Page 12 of 14
Grassy Branch — Condition Assessment Report
Union County Water

manhole. When the lateral train reaches the connection (as confirmed by
standard CCTV equipment), the bladder is inflated and held at the recommended
air pressure while the connection seal is allowed to cure. Once cured, the bladder
is removed and the service is returned to use.
Estimated Cost: $10,500.00 per CIPP lateral seal
2. Reconnecting Laterals to Main Line
This process consists of reconnecting a lateral to a sewer main by use of a saddle
or fitting. It is used to repair break-in taps or other defective connections, which
are very common in older collection systems. These connections are very
susceptible to ground water infiltration and root intrusion. It is recommended that
break-in taps be replaced by a saddle connection.
Estimated Cost: $6,000.00 per service lateral
3. Installation of Clean -outs
Many older service laterals were installed without clean -outs at the property line
(right-of-way). Without them, it can be very difficult to remove blockages that can
occur in the laterals. If a clean -out on private property is used, it can be difficult to
determine whether the responsibility for removing a blockage lies on the property
owner or the municipality. To allow for easier maintenance, we recommend that
all service laterals have clean -outs installed at the property line or edge of right-of-
way.
Estimated Cost: $1000.00 per clean -out

V. REPAIR I REPLACEMENT / REHABILITATION (RRR) RECOMMENDATIONS WITH
COST ESTIMATES
Overall, the collection system was found to be in very good condition. Only a few active
infiltration defects were identified; most were in manholes or at the manhole/pipe
connection. Because there are so few repairs, the price of each repair can be expected to
be highly inflated if this work is done as a standalone project. We recommend including
these few repairs in with another sewer rehabilitation project in order to obtain better
overall pricing.

VI. CONCLUSION
This report presents the data, results, and recommendations from the evaluation of the
Grassy Brach gravity collection system. Based on the CCTV inspection results, there are
only a few minor defects in the collection system that need to be addressed.
We encourage Union County Water to move forward with the recommendations presented
in this study. Following these repair recommendations will reduce 1/1 reaching the WRF.
Furthermore, tending to these issues will prevent these defects from getting worse over
time. We also recommend that the County include these repairs in with another sewer
rehabilitation project for the best possible cost benefit.
Hydrostructures, P.A. has extensive experience with trenchless rehabilitation engineering,
and we would welcome the opportunity to assist the County with the implementation of
RRRs proposed in this report.

4 PROJECT BACKGROUND
The Grassy Branch WRF is currently permitted for a monthly average daily discharge of 0.050 MGD to
Crooked Creek via NPDES permit NC0085812. The facility serves three schools, two subdivisions, and
several additional private parcels. The facility has been issued Notice of Violations (NOVs) for flow,
biochemical oxygen demand (BOD), ammonia, total suspended solids, fecal coliform, and pH over the last
several years dating back to 2018. It has been determined that the majority of the NOVs have been a
result of record rainfall events; however, over -allocation of sewer capacity has also contributed to
discharge permit compliance issues. The County has actively been addressing inflow and infiltration (I &
1), but the over -allocation of sewer capacity must be addressed through a plant expansion. The County
has entered into a Special Order of Consent (SOC) to address the capacity issues through expansion of
the facility, and a schedule of compliance is included in Appendix E.
The facility's NPDES discharge permit includes provisions for expansion to 0.120 MGD upon issuance of
an Authorization to Construct from NCDEQ. The effluent discharge limits for the facility at 0.120 MGD are
summarized in Table 1 below, and the complete NPDES discharge permit is included in the Appendix D.

A. (4.) ELECTRONIC REPORTING - DISCHARGE 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.)
• Section D. (2.)
• Section D. (6.)
• Section E. (5.)
Signatory Requirements
Reporting
Records Retention
Monitoring Reports
1. Reporting Reauirements [Supersedes Section D. (2.) and Section E. (5.) (a)l
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. The eDMR system may be
accessed at: ems://deg.nc.izov/about/divisions/water-resources/edmr.
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
following address:
NC DEQ / Division of Water Resources / Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
See "How to Request a Waiver from Electronic Reporting" section below.
Monitoring results obtained during the previous month(s) shall be summarized for each month and
reported via the eDMR system no later than the last calendar day of the month following the
completed reporting period. 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, 2025, the permittee must electronically report the following compliance
monitoring data and reports, when applicable:

• Sewer Over0owBypass 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 submissions must start by the dates listed in the "Reporting Requirements" section above.
3. How to Request a Waiver from Electronic Reoortine
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 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.

PART II
STANDARD CONDITIONS FOR NPDES PERMITS
Section A. Definitions
2/Month
Samples are collected twice per month with at least ten calendar days between sampling events. These samples shall be
representative of the wastewater discharged during the sample period.
3/Week
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
The period from midnight of one day until midnight of the next day. However, for purposes of this permit, any
consecutive 24-hour period that reasonably represents the calendar day may be used for sampling.
Calendar Week
The period from Sunday through the following Saturday.
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

(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at a
constant time interval. Use of this method requires prior approval by the Director. This method may only be
used in situations where effluent flow rates vary less than 15 percent. The following restrictions also apply:
➢ Influent and effluent grab samples shall be of equal size and of no less than 100 milliliters
➢ Influent samples shall not be collected more than once per hour.
➢ Permittees with wastewater treatment systems whose detention time < 24 hours shall collect effluent grab
samples at intervals of no greater than 20 minutes apart during any 24-hour period.
➢ Permittees with wastewater treatment systems whose detention time exceeds 24 hours shall collect effluent
grab samples at least every six hours; there must be a minimum of four samples during a 24-hour sampling
period.
Continuous flow measurement
Flow monitoring that occurs without interruption throughout the operating hours of the facility. Flow shall be
monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance
activities on the flow device.
Daily Discharge
The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling. For pollutants measured in units of mass, the "daily discharge" is calculated as
the total mass of the pollutant discharged over the day. For pollutants expressed in other units of measurement, the
"daily discharge" is calculated as the average measurement of the pollutant over the day. (40 CFR 122.2; see also
"Composite Sample," above.)
Daily Maximum
The highest "daily discharge" during the calendar month.
Daily Sampling
Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the
permit. Sampling shall be conducted on weekdays except where holidays or other disruptions of normal operations
prevent weekday sampling. If sampling is required for all seven days of the week for any permit parameter(s), that
requirement will be so noted on the Effluent Limitations and Monitoring Page(s).
DWR or "the Division"

Effluent
Wastewater discharged following all treatment processes from a water pollution control facility or other point source
whether treated or untreated.
EMC
The North Carolina Environmental Management Commission
EPA
The United States Environmental Protection Agency
Facility Closure
Cessation of all activities that require coverage under this NPDES permit. Completion of facility closure will allow this
permit to be rescinded.
Geometric Mean
The Nth root of the product of the individual values where N = the number of individual values. For purposes of
calculating the geometric mean, values of "0" (or "< [detection level]") shall be considered = 1.
Grab Sample
Individual samples of at least 100 mL collected over a period of time not exceeding 15 minutes. Grab samples can be
collected manually. Grab samples must be representative of the discharge (or the receiving stream, for instream
samples).

Hazardous Substance
Any substance designated under 40 CFR Part 116 pursuant to Section 311 of the CWA.
Instantaneous flow measurement
The flow measured during the minimum time required for the flow measuring device or method to produce a result in
that instance. To the extent practical, instantaneous flow measurements coincide with the collection of any grab
samples required for the same sampling period so that together the samples and flow are representative of the discharge
during that sampling period.
Monthly Average (concentration limit)

PART IV
SPECIAL CONDITIONS FOR MUNICIPAL FACILITIES
Section A. Definitions
In addition to the definitions in Part II of this permit, the following definitions apply to municipal facilities:
Indirect Discharge or Industrial User
Any non -domestic source that discharges wastewater containing pollutants into a POTW regulated under section
307(b), (c) or (d) of the CWA. [40 CFR 403.3 (i) and 0) and 15A NCAC 02H .0903(b)(11)]
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
sewage or industrial wastes of a liquid nature. It also includes the collection system, as defined in 15A NCAC 2T
.0402, only if it conveys wastewater to a POTW treatment plant. The term also means the local government
organization, or municipality, as defined in section 502(4) of the CWA, which has jurisdiction over indirect discharges
to and the discharges from such a treatment works. In this context, the organization may be the owner of the POTW
treatment plant or the owner of the collection system into which an indirect discharger discharges. This second type of
POTW may be referred to as a "satellite POTW organization." [15A NCAC 02H .0903(b)(26)]
"Significant Industrial User" or "SIU"
An Industrial User that discharges wastewater into a publicly owned treatment works and that [15A NCAC 02H
.0903(b)(33)]:
1. Discharges an average of 25,000 gallons per day or more of process wastewater to the POTW (excluding sanitary,
noncontact cooling and boiler blowdown wastewaters); or
2. Contributes process wastewater which makes up five percent or more of the NPDES or non -discharge permitted
flow limit or organic capacity of the POTW treatment plant. In this context, organic capacity refers to BOD, TSS
and ammonia; or
3. Is subject to categorical standards under 40 CFR Part 403.6 and 40 CFR Parts 405-471; or
4. Is designated as such by the Permittee on the basis that the Industrial User has a reasonable potential for adversely
affecting the POTW's operation or for violating any pretreatment standard or requirement, or the POTW's effluent
limitations and conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options;
5. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraphs 1 or 2 of this definition above has no reasonable potential for adversely affecting the
POTW's operation or for violating any pretreatment standard or requirement, the POTW's effluent limitations and
conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options, and thus is not a
Significant Industrial User (SIU); or
6. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraph 3 of this definition above meets the requirements of 40 CFR Part 403.3(v)(2) and thus is a
non -significant categorical Industrial User.

All POTWs must provide adequate notice to the Director of the following [40 CFR 122.42(b)]:
1. Any new introduction of pollutants into the POTW from an indirect discharger, regardless of the means of
transport, which would be subject to section 301 or 306 of CWA if it were directly discharging those pollutants;
and
2. Any substantial change in the volume or character of pollutants being introduced by an indirect discharger as
influent to that POTW at the time of issuance of the permit.
3. For purposes of this paragraph, adequate notice shall include information on (1) the quality and quantity of effluent
introduced into the POTW, and (2) any anticipated impact that may result from the change of the quantity or
quality of effluent to be discharged from the POTW.
Section C. Municipal Control of Pollutants from Industrial Users.
1. Effluent limitations are listed in Part I of this permit. Other pollutants attributable to inputs from Industrial Users
discharging to the POTW may be present in the Permittee's discharge. At such time as sufficient information
becomes available to establish limitations for such pollutants, this permit may be revised to specify effluent
limitations for any or all of such other pollutants in accordance with best practicable technology or water quality
standards.
2. Prohibited Discharges
a. The Permittee shall develop and enforce their Pretreatment Program to implement the prohibition against the
introduction of pollutants or discharges into the waste treatment system or waste collection system which
cause or contribute to Pass Through or Interference as defined in 15A NCAC 02H .0900 and 40 CFR 403. [40
CFR 403.5(a)(1)]
b. The Permittee shall develop and enforce their Pretreatment Program to implement the prohibitions against the
introduction of the following wastes in the waste treatment or waste collection system [40 CFR 403.5(b)]:
(1) Pollutants which create a fire or explosion hazard in the POTW, including, but not limited to,
wastestreams with a closed cup flashpoint of less than 140 degrees Fahrenheit or 60 degrees Centigrade
using the test methods specified in 40 CFR 261.21;
(2) Pollutants which cause corrosive structural damage to the POTW, but in no case discharges with pH lower
than 5.0, unless the works is specifically designed to accommodate such discharges;
(3) Solid or viscous pollutants in amounts which cause obstruction to the flow in the POTW resulting in
Interference;
(4) Any pollutant, including oxygen demanding pollutants (BOD, etc.) released in a Discharge at a flow rate
and/or pollutant concentration which will cause Interference with the POTW;
(5) Heat in amounts which will inhibit biological activity in the POTW resulting in Interference, but in no
case heat in such quantities that the temperature at the POTW Treatment Plant exceeds 40°C (104°F)
unless the Division, upon request of the POTW, approves alternate temperature limits;
(6) Petroleum oil, non -biodegradable cutting oil, or products of mineral oil origin in amounts that will cause
Interference or Pass Through;
(7) Pollutants which result in the presence of toxic gases, vapors, or fumes within the POTW in a quantity that
may cause acute worker health and safety problems; or
(8) Any trucked or hauled pollutants, except at discharge points designated by the POTW.
c. The Permittee shall investigate the source of all discharges into the POTW, including slug loads and other
unusual discharges, which have the potential to adversely impact the Permittee's Pretreatment Program and/or
the operation of the POTW.
The Permittee shall report such discharges into the POTW to the Director or the appropriate Regional Office.
Any information shall be provided orally within 24 hours from the time the Permittee became aware of the
circumstances. A written submission shall also be provided within 5 days of the time the Permittee becomes
aware of the circumstances. The written submission shall contain a description of the discharge; the
investigation into possible sources; the period of the discharge, including exact dates and times; if the
discharge has not ceased, the anticipated time it is expected to continue; and steps taken or planned to reduce,
eliminate, and prevent reoccurrence of the noncompliance,

Engineer Certification for Grassy Branch Water
Reclamation Facility Special Order by Consent
1. Introduction
This process certification is in support of the Union County Public Works (UCPW) application for a
Special Order by Consent (SOC) for the Grassy Branch Water Reclamation Facility (WRF). This
correspondence is an independent professional report on the status of the Grassy Branch WRF to meet the
existing National Pollutant Discharge Elimination System (NPDES) permit limits during the period the
WRF will be operating under the SOC. The following narratives specifically address the SOC application
requirements. It should be noted that all engineering determinations are supported by a detailed process
evaluation published separately from this signed and sealed certification.
2. Summary of Existing WRF Infrastructure
The Grassy Branch WRF is an extended aeration package treatment plant (PT?) constructed by Hydro -
Aerobics Package Wastewater Treatment Systems in 1997. The WRF is permitted for a maximum month
design flow of 50,000 gallons per day (gpd), or 0.05 million gallons per day (mgd). Union County
operates the facility NPDES permit NC0085812. Table 2-1 summarizes the final effluent permit limits for
five-day biochemical oxygen demand (BOD5), total suspended solids (TSS), ammonia (NH3-N), and fecal
colifonn.
The Grassy Branch WRF consists of coarse screening, flow equalization, two conventional aeration
basins with coarse bubble diffusers, two secondary clarifiers, a sand filter, and ultraviolet (UV)
disinfection. Waste activated sludge (WAS) is processed in an aerobic digester for volatile solids
reduction. The digested solids are then pumped to a tanker truck and transported to the Crooked Creek
WRF for further stabilization. Table 2-2 summarizes the design criteria of the existing Grassy Branch
WRF infrastructure.

3. Flow Evaluation
The historical data indicate that influent flows in excess of the permitted design capacity of the WRF have
resulted in final effluent permit violations for flow, conventional pollutants, and bacterial pollutants. The
County has attributed the majority of the Notice of Violations (NOVs) to record rainfall events in the
region. The County also acknowledges that more sewer connections have been allocated to the Grassy
Branch WRF than available capacity. Hazen recommends a permanent increase in the design maximum
month flow from 0.05 mgd to 0.120 mgd.

Two parallel analysis were run to verify the proposed 120,000 gpd maximum month design capacity. The
first analysis used the average day wastewater flow rates published in 1 SA NCAC 02T .0114 (Wastewater
Design Flow Rates). The wastewater unit flow rates for schools and dwelling units were applied to the
number of students and homes served by the Grassy Branch WRF. Due to the proximity to schools, an
assumption of three bedrooms per dwelling unit was used in the analysis. The second flow analysis used a
Hazen and Sawyer statistical approach for evaluating flow metrics and peaking factors.
Table 3-4 summarizes the proposed design annual average for both analyses. Both calculation methods
result in an annual average flow within 20%. The statistically -derived maximum month, maximum week,
and maximum day peaking factors are also summarized in Table 3-4. The more conservative annual
average flow of 67,000 gpd was used to fully account for the impact of the seasonal flow variation
attributed to the three schools.

4. Evaluation and Optimization of Existing Treatment Units
4.1 Historical Influent Characterization Data
Tables 4-1 and 4-2 summarize the maximum month, maximum week (e.g., 7-day), and maximum day
peaking factors (PF) and influent concentrations and loads, respectively. Data was evaluated from 2015
through 2018. Data from the year 2019 does not account for the impact of the seasonal flow variation and
Fijgineer Certification for Grassy Branch Water Reclamation Facility Page 4 ot'9

was therefore not included in the analysis. A statistical approach was used for evaluating influent
characterization metrics and peaking factors. The original design influent loads and concentrations for the
WRF are not known, as the criteria were not provided in the manufacturer's Wastewater Treatment
Systems Operations and Maintenance (O&M) manual. The proposed design concentrations and loads for
the Grassy Branch WRF improvements project are summarized in Table 4-3.

4.2 Influent Pumps
The existing influent pumps are rated at 130,000 gpd each at 15 feet of total dynamic head (TDH), which
allows for 260,000 gpd with both units in service. The existing pumps cannot be further optimized and do
not have sufficient capacity for the proposed maximum month design flow. Additional pumps will be
needed to provide adequate capacity with redundancy for the proposed improvements.
4.3 Influent Screening
Influent screening is comprised of a manual coarse bar screen designed for a peak hour flow of
150,000 gpd (e.g., 2.5 times the maximum month design flow of 50,000 gpd). The existing bar screen
cannot be further optimized. Additional screening unit(s) are required as the existing screen does not have
adequate capacity to meet the proposed maximum month design flow.
4.4 Flow Equalization
Existing flow equalization consists of two 7,700-gallon basins, or 15,400 gallons total volume. The
existing flow equalization basins cannot be further optimized, as the basins do not provide adequate
hydraulic retention time to attenuate the proposed maximum month design flow. Additional equalization
volume is required as part of the facility improvements.
4.5 Secondary Treatment Train
The secondary treatment process consists of a 50,000 gpd (e.g., two trains in service) conventional
aeration activated sludge process. The PTP is equipped with coarse bubble diffusers and two rotary lobe
positive displacement blowers. The aeration basins were designed to provide a 24-hour hydraulic
retention time at the current maximum month design flow of 0.05 mgd. However, only 15 hours of
hydraulic retention time is provided at current flows. The WAS flow is not measured nor were solids
hauling records available for the determination of the solids retention time (SRT). The positive
displacement blowers and coarse bubble aeration system does not have adequate capacity to treat the
existing annual average, maximum month, maximum week, and maximum day loads with one blower out
of service. Based on the available hydraulic, process, and equipment capacity, the secondary process
cannot be further optimized to treat additional flow. New process volume and aeration equipment is
required as part of the facility improvements for the proposed maximum month design flow.
4.6 Secondary Clarifiers
The Grassy Branch WRF has two 10 foot diameter secondary clarifiers. Each clarifier has a sidewater
depth of 10 feet. The reported historical peak day surface overflow rates (SOR) and surface loading rates
(SLR) are 1,823 gpd/SF and 63 lb/SF, respectively. The calculated overflow and loading rates are
excessive compared to standard engineering best practices. Typical design overflow rates range from
300 to 1,000 gpd/SF. Typical solids loading rates range from 15 to 35 lb/day-SF. The existing secondary
F rigineer Certification for Grassy Branch Water lteclantation Facility Page 6 of 9

Hazen
clarifiers are undersized and cannot be further optimized. New secondary clarification capacity is required
for the proposed improvements.
4.7 Tertiary Filtration
The WRF has two mixed media (anthracite/sand) tertiary filters each with a surface area of 18.75 SF. The
historic peals day hydraulic loading rate and solids loading rate are 7.3 gpm/SF and 3.91b/SF,
respectively. The calculated hydraulic and solids loading rates are excessive compared to standard
engineering best practices. Typical filter design hydraulic and solids loading rates are 5 gpd/SF and
3 lb/day-SF, respectively. The existing mixed media filters cannot be further optimized. New filtration
capacity is required for the proposed improvements.
4.8 UV Disinfection
The existing UV disinfection system wasinstalled in the original chlorine contact chamber as a retrofit
project. Routine maintenance is problematic as it requires that UCPW staff remove grating and stand in
the channel. The existing UV system cannot be further optimized and does not have the required capacity
to meet the proposed maximum month design flow. An additional unit(s) will be required to meet the
proposed peak day flow.
4.9 Effluent Flow Measurement
Effluent flow is measured via a discharge weir. The existing weir will require replacement to
accommodate the proposed maximum month design flow.
4.10 Post Aeration
The facility does not have a formal post aeration system. Aeration is achieved through the effluent flow
weir and head drop to the final effluent discharge location. The facility has not had any effluent permit
violations for dissolved oxygen, so it is not anticipated that additional post aeration capacity will be
needed.
4.11 Aerobic Digester
The existing aerobic digester equalization consists of two 4,500-gallon basins for 9,000 gallons of total
volume. The aerobic digester is equipped with coarse bubble diffusers connected to the secondary
treatment positive displacement blowers. The aerobically digested solids are pumped out and transported
to the Crooked Creek WRF for final disposal. Additional aerobic digestion volume will be needed to
accommodate the proposed maximum design flow. The final disposal method will not be altered.

4.12 Operational Procedures
Current operating procedures are consistent with best practices for operation of a wastewater treatment
facility. Housekeeping and maintenance of the facility are excellent for industry standards. No operational
changes are recommended at this time.
5. Specific Requirements of the SOC
5.1 Evaluation of Existing Treatment Units and Operational Procedures
The existing Grassy Branch WRF does not have adequate process capacity to adequately treat the current
flows and loads and maintain NPDES permit compliance. The WRF cannot be firther optimized or
operated in a manner that achieves compliance with final effluent permit limits. Additional process units
are necessary to be in compliance with the existing final effluent permit limits.
5.2 The Effluent Limits that the Facility Could Be Expected to Meet if Operated at Their Maximum
Efficiency during the Term of the Requested SOC (Consider Interim Construction Phases)
The historical data indicate influent flows greater than the permitted maximum month design flow results
in final effluent permit violations for flow, BOD, TSS, ammonia, and fecal coliform. Table 5-1
summarizes the requested interim effluent limits for the Grassy Branch WRF. The requested limits are
based on the 2015 to 2018 historical data in conjunction with the process modeling and WRF evaluation.
It is not anticipated that construction phases will be applicable to the proposed upgrade project, so tiered
interim limits are not necessary.

5.3 Any Other Actions Taken to Correct Problems Prior to Requesting the SOC
The County has been actively involved in reduction of infiltration and inflow (W) in the collection
system. A Phase 1 I&I study was commissioned in 2016 to broadly determine problem areas. A Phase 2
Engineer Cerlitication for Grassy Branch Water Reclamation Facility Page 8 of 9

study in 2017 focused on repair efforts readily identified in the Phase 1 study. The Phase 2 study also
included wet weather monitoring. In 2018, Phase 3 efforts included confirming the effectiveness of
previous repair efforts, extensive CCTV review of the entire collection system, and the continuation of
repair efforts. Phase 4 of the I&I reduction effort started in 2019. This phase consists of a review of dty
and wet weather data and patterns and on -going inspection of the collection system. As of January 2019,
the entire Grassy collection system has been surveyed by CCTV. As of May 2019, 42 manholes have
been grouted and 48 inflow collectors installed.
Union County has also been actively evaluating process changes at the WRF to minimize NOW Staff
has taken several precautionary measures in anticipation of high flow events, as follows:
Bypassing of filters
Increased monitoring of WRF to include frequent visits during a wet weather event and constant
monitoring of telemetry via SCADA
Control of air input to aeration basins to retain suspended solids:
o Shutting down of all compressors except one.
o Reducing remaining compressor to 30 Hz.
o Shutting down all aerator drop legs except the first set.
6. Summary of Recommendations for Infrastructure Improvements
The historical data indicate the influent flows that exceed the permitted design capacity of the Grassy
Branch WRF have resulted in final effluent permit violations for flow, conventional pollutants, and
bacterial pollutants. The County has attributed the majority of the NOVs to record rainfall events in the
region. The County also acknowledges that more sewer connections have been allocated to the Grassy
Branch WRF than available capacity. Hazen recommends a permanent increase in the design maximum
month flow from 0.05 mgd to 0.120 mgd.
Hazen recommends an expansion of the Grassy Branch WRF which would include larger influent pumps,
an additional secondary treatment train and secondary clarifier, the addition of cloth disk filters, and a
new UV disinfection systern. Hydraulics would be evaluated during detail design. Existing unit processes
will remain in service during construction. It is not anticipated that construction activity will affect the
current facility performance.

Expansion Alternatives
DRAFT
Introduction
The Grassy Branch Water Reclamation Facility (WRF) Expansion project will expand the treatment
capacity of the WRF from 50,000 gallons per day (gpd) to 120,000 gpd. The two alternatives evaluated in
this technical memorandum (TM) include summary of unit processes and cost comparison of: (1)
installation of a parallel 70,000 gpd package train with flow equalization, sludge storage, aeration tanks,
and clarifiers while maintaining the existing 50,000 gpd package train in its current configuration, and (2)
installation of packaged 120,000 gpd aeration tanks and clarifiers while reconfiguring the existing
aeration tanks to operate as flow equalization volume. Alternative 2 is evaluated with two options: (A)
utilizing existing sludge storage and flow equalization tanks for sludge storage; (B) including a new
sludge storage tank with the new package plant. Both alternatives will include new influent pumping,
chemical storage and feed, blowers, cloth disk filters, UV disinfection, effluent outfall piping, electrical
service and switchgear, instrumentation & controls, and general site work.

2. Design Parameters
2.1 Background
March 31, 2023
Union County Water (UCW) operates the facility under the National Pollutant Discharge Elimination
System (NPDES) Permit number NC0085812. Effective May 1, 2022, UCW was issued updated effluent
limits to the Grassy Branch WRF related to an application for a Special Order by Consent (SOC) to
expand the facility from 50,000 gpd to 120,000 gpd. Table 2-1 summarizes the final effluent permit limits
for five-day biochemical oxygen demand (BODs), total suspended solids (TSS), ammonia (NH3-N), and
fecal coliform (FC).

2.2 Influent Design Flows
Influent design flows were developed by Hazen in the Grassy Branch WRFProcess Evaluation TM (July
2019). Table 2-2 summarizes the proposed design Annual Average (AA), Maximum Month (MM),
Maximum 7-day, and Maximum Day (MD) flows and peaking factors. Table 2-3 summarizes the
proposed design annual average and maximum month concentrations and loads. The proposed design
influent concentrations were selected based on historical data and typical values for medium strength
domestic wastewater.
Equipment proposals were requested based upon the design flow parameters listed in the two tables
below. Secondary proposals were requested based upon the flow scenario with adequate equalization
storage volume to limit peak flow through Grassy Branch WRF to "2Q", or 240,000 gpd.

3. Alternatives Comparison
The following two design scenarios were examined:
Alternative 1: Installation of a parallel 70,000 gpd package train with flow equalization, sludge storage,
aeration tanks, and clarifiers while maintaining the existing 50,000 gpd package train in its current
configuration.
Alternative 2: Installation of package 120,000 gpd aeration tanks and clarifiers while reconfiguring the
existing aeration tanks to operate as flow equalization volume. Alternative 2 was divided into two
subalternates (2A and 2B) that examined two different sludge storage configurations.
Both alternatives will incorporate the following new common facilities:
• Influent Pumps & Pump Station
• Lime Storage & Feed Pumps
• Process Blowers
• Cloth Disk Filter
• UV Disinfection
• Effluent Outfall & Piping
• Electrical Service & Switchgear
• Instrumentation & Controls
• General Site Work
3.1 Site Layout
Appendix A includes a Parcel Map and the FEMA Floodplain Map associated with the facility. A flow
schematic of the existing facilities at Grassy Branch is shown in Figure 3-1.
Both alternatives will require extensive site grading to provide a level surface for the proposed facility
expansion. The area due south of the existing treatment train where the proposed basins will be located is
within the 100-year floodplain. USGS topographic maps denote a secondary stream feeding into Grassy
Branch from the pond southwest of the WRF property. All work will likely be within the riparian buffers
designated by Union County ordinance 70.030.
The existing Union Power Cooperative power distribution utility pole for the site will need to be relocated
to accommodate the proposed facility expansion.
The existing 150-foot Duke Energy Transmission right-of-way corridor will restrict the available footprint
for expansion on the southern portion of the property.
The facility's potable water well will need to be decommissioned due to the proposed facility expansion.

3.2 Common Facilities
Influent Pump Station
The existing influent pump station will be replaced with a new influent pump station with the same wet
well and valve vault configuration. The wet well will have three 5-HP submersible pumps that will
operate with two (2) duty pumps and one (1) standby pump. The following design conditions were
identified for influent pump selection:
• Max Month Flow — 84 gpm at 30-feet TDH
• Max Day Flow — 326 gpm at 40-feet TDH
Variable frequency drives (VFDs) will be installed to manage variable flows.
Submersible pump selections have been requested from Flygt. UCW uses Flygt pumps at their other
wastewater treatment facilities and could streamline maintenance by maintaining a single pump
manufacturer. Other pump manufacturers can be considered if UCW has additional preferences.
Influent Screening
The WRF currently relies on a manual bar rack located inside the package plant distribution box. The
introduction of a new fine screen sized to meet the increased influent flows listed in Section 2 would
increase the plant's screening reliability.
A fine screen, such as the Lakeside Raptor Micro Strainer, could serve as a centralized screening facility
for the WRF for Alternative 2. An initial selection would consist of the following features:
• 326 gpm capacity
• 17-feet x 3-feet footprint
• 2-hp Drive
• 15 gpm at 60 psi water requirement
Alternative 1 is scoped herein with a screen for each package train due to the complexity of piping from a
single screen to both sets of aeration tanks.
Cloth Disk Filter
A single cloth disk filter system would replace the existing mixed media filter system at the WRF.
Initial pricing and selection of cloth disk filter was based on the Kruger system, which is used at other
UCW wastewater treatment facilities.
The initial selection from Kruger consists of the following features:
• 326 gpm capacity
• Footprint: 100-square feet
Union County Water (UCW) Page 5 of 11
Grassy Branch Water Reclamation Facility Expansion Alternatives
DRAFT

Hazen March 31, 2023
• Number of Discs: 2
• Backwash Requirement: 14 gpm
Under Alternative 2, greater equalization storage volume may result in adequate volume to limit peak
flow through the plant to "2Q", or 240,000 gpd. Per conversations with Kruger, this could allow the
system selection to remove one of the two required disk filters (approximately $10,000 per disk filter).
Given the minimal cost savings and the built-in system redundancy of having multiple disk filters, it is
recommended to install the higher capacity unit.
Ultraviolet (UV) Disinfection
A new UV Disinfection system will be required to meet the updated capacity requirements. The new
system would allow for one duty and one standby unit (i.e. banks) to meet the peak day flow. The
selection consists of the following features:
• 326 gpm capacity
• Footprint: 24-feet x 3-feet
• Number of Banks: 2
• Number of Lamps per Bank: 16
• UV Transmittance @ 253.7 nm: 65% (to be validated during design)
• Can be installed in Series or Parallel
The initial pricing and selection of a UV disinfection system was based on a TrojanUV system, which is
used at other UCW wastewater facilities.
Under Alternative 2, greater equalization storage volume may result in adequate volume to limit peak
flow through the plant to "2Q", or 240,000 gpd. Per conversations with TrojanUV, this could adjust the
system selection to eight (8) lamps per bank. The smaller flow compatible unit would result in a $20,000
reduction in capital costs. Given the minimal cost savings and reliability at higher flows, it is
recommended to install the higher capacity unit.
Miscellaneous Work
The following describes miscellaneous work that will be required for both design alternatives:
New process piping will be installed to accommodate all related facility expansion work. For both
alternatives, flow will be split between the existing treatment train and the proposed treatment
train using valves and magnetic flow meters.
A new effluent outfall will be constructed adjacent to the existing outfall on Crooked Creek.
• Lime, for supplementary alkalinity addition, will be pumped to the influent splitter box for each
alternative. Currently lime is fed into the equalization portion of the package treatment plant.
Operators have reported lime buildup at the feed point within the equalization tank.

Only the existing equalization and sludge holding tanks were repaired and recoated in the most
recent upgrade project. The remaining interior tank coatings have reached the end of their useful
service life and these tanks will need to be recoated. The existing interior aeration basin coatings
(both alternatives) and clarifier coatings (Alternative 1 only) should be completely removed by
sandblasting and the interior surfaces recoated with a high solids epoxy system specifically
designated for wastewater immersion. After sandblasting, the cleaned steel surfaces should be
inspected for damage and surface loss. Any damaged areas of steel walls, floors, welds or
stiffeners should be repaired or replaced prior to recoating.
The existing mixed media filters and UV disinfection facilities will be demolished.
A new potable water line that will serve the facility to be installed and fed from the water main on
Old Fish Road.
Electrical system including utility service, generator, automatic transfer switch, switchgear, and
VFDs.
Systems integration of all new facility improvements.
3.3 Alternative 1
Along with the proposed improvements described in Section 3.2, Alternative 1 will incorporate a new
70,000 gpd package treatment plant to operate in parallel to the existing 50,000 gpd package treatment
train. A flow schematic for Alternative 1 is shown in Figure 3-2.
Flow Equalization
The existing package treatment plant has a flow equalization volume of 15,400 gallons. The flow
equalization tank has two dedicated 2-horsepower (HP) rotary lobe positive displacement (PD) blowers to
supply process air to the system via coarse bubble diffusers.
The proposed new package treatment plant would include a flow equalization chamber of approximately
23,100 gallons to provide a total equalization volume of 38,500 gallons. The proposed flow equalization
tank would include a coarse bubble aeration system and three 5-HP rotary lobe PD blowers that would
operate in two duty, one standby configuration. Equalized flow will be repumped to the influent
distribution box of the package plant.
Secondary Treatment
The existing package treatment plant consists of two 25,000 gallon aeration basins and two 10-foot
diameter secondary clarifiers. WAS from the secondary clarifiers is routed to a 9,000 gallon sludge
holding tank. Aeration basins and sludge holding tanks utilize two 7.5-HP rotary lobe PD blowers to
supply process air via coarse bubble diffusers. Currently plant staff must operate both blowers as duty
blowers to meet the aeration demand.
Union County Water (UCW) Page 7 of 11
Grassy Branch Water Reclamation Facility Expansion Alternatives
DRAFT

Hazen March 31, 2023
The proposed new package treatment plant would include two 35,000 gallon aeration basins and two 14-
foot diameter secondary clarifiers. WAS from the proposed secondary clarifiers will be routed to a new
11,000 gallon sludge holding tank. The proposed aeration basins and sludge holding tanks would include
a coarse bubble aeration system and three 10-HP rotary lobe PD blowers that would operate in a two duty,
one standby configuration. The blowers would be configured to operate on VFDs to provide operation
flexibility.
The initial pricing and selection of a secondary treatment system was based on a Pro -Water Systems
package treatment plant. The initial pricing and selection of aeration blowers was based on Aerzen rotary
lobe PD blowers, which are used at other UCW wastewater facilities.
3.4 Alternative 2
Along with the proposed improvements described in Section 3.2, Alternative 2 will incorporate a new
120,000 gpd package treatment plant.
Flow Equalization
Under this alternative the two 25,000 gallon aeration tanks in the existing package treatment plant would
be converted to flow equalization thus creating a total flow equalization volume of 50,000 gallons. The
proposed flow equalization system is intended to leverage the existing aeration blowers and diffusers.
Equalized flow will be drained to the influent pump station manhole.
Secondary Treatment
The proposed new package treatment plant would include two 60,000 gallon aeration basins and two 16-
feet diameter secondary clarifiers.
WAS could be stored in two possible ways in this alternative, thereby differentiating Alternatives 2A and
2B:
Alternative 2A: The flow equalization and sludge holding tanks within the existing package
treatment plant would be refurbished to act as a single sludge holding tank with a proposed
volume of 24,500 gallons. New piping and a WAS pump would be required in this scenario to
direct flow from the new basins to the sludge holding tank. A flow schematic for Alternative
2A is shown in Figure 3-3.
• Alternative 2B: A new sludge holding tank at the head of the proposed package treatment
plant with a proposed volume of 19,000 gallons. This system would utilize the pressure from
the RAS airlift system, like the currently installed package treatment plant, to transfer WAS
from the secondary clarifiers to the sludge holding tank. A flow schematic for Alternative 2B is
shown in Figure 3-4.

The proposed aeration basins would include a coarse bubble aeration system and three 15-HP rotary lobe
PD blowers that would operate in a two duty, one standby configuration. The blowers would be
configured to operate on VFDs to provide operation flexibility.
A site layout of Alternative 2B is shown in Figure 3-5.
The initial pricing and selections are based on Pro -Water Systems and Aerzen, similar to Alternative 1.
The following work in the existing package treatment plant is recommended under Alternative 213:
Interior walls of the existing package treatment plant will be partially removed to consolidate
equalization volume.
Holes will be cored into the dividing wall between the two proposed equalization cells to create a
single equalization system.
• The existing secondary clarifiers will be demolished.
The existing flow equalization and sludge holding volume will be abandoned in -place.

5. Operational Considerations
UCW may consider alternative configurations depending on how they choose to operate the selected
alternatives, including the following:
Sole sourcing of certain equipment and systems could streamline operation and maintenance of
UCW's wastewater treatment facilities.
Package plants are available in two different options: (1) field assembled plants and (2) pre -
manufactured plants. The existing package plant at Grassy Branch WRF is a field assembled
plant. The existing package plant at Olde Sycamore WRF is a pre -manufactured plant. Pre -
manufactured plants are limited to dimensions that allow for ground transport, whereas field
assembled plants allow for basin dimensions to be optimized. Field assembled plants were
considered in the development of the Section 4 Cost Summary.
Under Alternative 1, flow into each package treatment plant would be controlled by modulating
valves and flowmeters. The modulating valves may create a restriction that could lead to nuisance
valve clogging. A single screen channel upstream of the influent pump station may be considered
as an alternate.
Under Alternative 2A, WAS transfer to the sludge holding tanks from the proposed treatment
train requires a transfer pump. Package plants, like the existing treatment train, typically have the
sludge holding tank at the head of the package treatment train and WAS is transferred using airlift
piping.
The proposed site plan should provide adequate access for sludge hauling and chemical delivery
vehicles. Currently large transportation vehicles must back into the plant property.
Addition of a potable water service connection from Old Fish Road.
Addition of a bathroom and/or eyewash station (not included in this TM).

EQUIPMENT CORPORATION

Raptor° Inclined Micro Strainer
Removes Solids Efficiently
The Lakeside Raptor® Micro Strainer is an efficient, proven screening technology for removal of inorganic solids that can
be harmful to downstream equipment in municipal and industrial wastewater applications. Ideal for small treatment
facilities, the Raptor® Micro Strainer utilizes a semicircular screenings basket to capture debris, such as plastics, hygienic
articles and fibers. The Raptor® Micro Strainer features, including the screw conveyor, are all stainless steel construction
(304 or 316) to handle the most severe conditions.
At 35° to 45' angle of inclination, the Raptor• Micro
Strainer provides high removal efficiency using a
perforated plate or wedge wire basket with small
openings ranging from 0.04 to 0.25 inches (1 to 6 mm).
A central screw conveyor with a cleaning brush removes
the captured solids from the screenings basket and
transports the debris for disposal. As the solids are being
conveyed, they are macerated to break down large fecal
matter, and then washed using a two -stage screenings
wash system to return organic material back to the
wastewater stream. The washed screenings are
compacted and dewatered prior to being discharged,
thereby reducing the volume and weight to a dry solids
content of 40 percent, ultimately reducing disposal cost.
Raptor® Micro Strainer Raptor® Micro Strainer
with Bagger with Weather Protection
Superior design and construction
• All stainless steel construction resists corrosion
• Combines 4 processes in one unit (screens,
washes, compacts and dewaters)
• Dual spray wash system provides cleaner
discharge screenings
• Integrated compaction zone reduces volume
and weight for reduced disposal cost
• Enclosed transport tube and optional bagger
attachment reduce odors
• Hinged support to pivot screen out of channel
for maintenance
• Removable bearing bars promote longer
brush life without disassembling the screen
• Tank -mounted screens and explosion -proof
designs are available
• Optional weather protection system protects
to 130 f below zero (minus 25' C)
Round openings are
available in sizes of
0. 12 inch and larger
Wedge wire screens
are available in bar
spacing of 0.12 inch

Raptor° Vertical Micro Strainer
for Applications with Limited Space
The Lakeside Raptor® Vertical Micro Strainer is designed
specifically to fit into limited access areas such as wet
wells, submersible pump stations, and underground
vaults. Similar to the inclined Raptor®Micro Strainer, it
combines the functions of screening, compacting and
conveying into a single unit.
The Raptor® Vertical Micro Strainer incorporates a
shafted screw with cleaning brush attached to the
flights in the basket area to convey captured material
for disposal. The split basket design provides easy
access to the brush assembly. The screen basket is either
perforated plate for wastewater applications or wedge
wire for special industrial applications.
An optional slide rail system is available to allow easy
removal of the screen from the wet well or vault. A quick
connect flange is used to make sure the screen's head
box lines up with the influent pipe connection.

Statement Regarding Competitive Transparency
Veolia takes all issues surrounding probity and confidentiality very seriously in all of its dealings with competitors and stakeholders. In this
spirit and for the sake of transparency, we inform you that the publicly traded parent company Veolia Environnement S.A., recently
acquired a 29.9% interest in Suez S.A ("Suez") and launched a public bid for the remainder of Suez' share capital. Consistent with our
commitment to competition law compliance, Veolia will continue to act entirely independent of Suez until all relevant antitrust approvals of
Veolia's acquisition of Suez have been obtained and we will of course let you know if this would change before the end of the tender
proceedings.
Specifically, none of Veolia's representatives sit on the board of Suez, Veolia has no influence over the strategy or operations of Suez,
and Veolia has no access to competitively sensitive information about Suez's operations. Accordingly, Veolia's ongoing project to acquire
Suez will have no effect on our participation in, or response to, this tender.
