Grassy Branch Water Reclamation Facility
Expansion Alternatives
1. 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
package plant basins to operate as flow equalization volume. 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
June 13, 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 (BOD5), 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 WRF Process 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. Upon initial review of
options for Alternative 2, the new package train is proposed to include a dedicated sludge holding tank
which will allow the entire existing package train volume to be used as flow equalization storage volume.
Flow equalization volume is commonly provided with package treatment plants as approximately 30% of
the working volume of the aeration tanks, as noted under the Section 3.3 Alternative 1 discussion.
Alternative 2 provides the opportunity for much higher volume based on using the existing basins.
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 WRF 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.
Union County Water (UCW) Page 4 of 12

June 13, 2023
Temporary construction easements (TCEs) will need to be obtained from both Duke Energy and the
adjacent property owner to construct the new facilities, perform site grading, and provide an adequate
construction access corridor. A preliminary meeting was held with Mr. Will Johnson from Duke Energy
on May 8, 2023 to discuss the proposed easements within the right-of-way, and Mr. Johnson noted that
the proposed TCEs seem amenable and he will continue assisting us as we develop site plans with
proposed easements. Preliminary TCEs are shown in Figure 3-2.
The facility's potable water well will need to be decommissioned due to the proposed facility expansion.
3.2 Common Facilities
Influent Pump Station
Three 5-horsepower (HP) submersible pumps that will operate in two (2) duty and one (1) standby
configuration are recommended to manage the wide range of flows resulting from the seasonal low flow
condition and the approximate "4Q" seasonal high peak flow condition. The following design conditions
were identified for influent pump selection:
• Max Month Flow — 84 gpm at 30-feet TDH (C = 110)
• Max Day Flow — 326 gpm at 40-feet TDH (C = 110)
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.
Upon review of standard circular manhole dimensions and the proposed pump dimensions, the proposed
three pumps will fit inside the existing 72-inch diameter manhole. The valve vault would require
complete demolition and replacement, and new wall penetrations and guide rails would be set in the
existing manhole. This work will require complete bypass pumping from an upstream manhole during
construction. An alternative is to provide a new manhole adjacent to the existing manhole to facilitate
construction without bypass pumping. The Section 4 Cost Summary includes a new manhole for project
scoping; however, this will be further evaluated during design.
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:
Union County Water (UCW) Page 5 of 12
Grassy Branch Water Reclamation Facility Expansion Alternatives

Hazen June 13, 2023
• 326 gpm capacity
• Footprint: 17-feet x 3-feet
• 2-HP Drive
• Water Requirement: 15 gpm at 60 psi
• 316 stainless steel construction
• Weather protection package included
The perforated screen opening can be selected to meet the desired screenings capture. '/4-inch openings
are projected to generate approximately 3 cubic yards per month of screenings. The proposed screen
includes a wash water system to rinse organics from the screenings in the conveyor section of the screen,
however some organics carryover can be expected. Therefore, a wider opening (e.g. 'h-inch opening) may
be selected to reduce screenings capture by approximately 50% and reduce organics carryover.
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
• 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.
Facility layout and design will include a valved bypass pipe around the filter.
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:
Union County Water (UCW) Page 6 of 12
Grassy Branch Water Reclamation Facility Expansion Alternatives

Hazen June 13, 2023
• 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 3-3.
Flow Equalization
The existing package treatment plant has a flow equalization volume of 15,400 gallons (30% of treatment
volume). The flow equalization tank has two dedicated 2-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 (33% of treatment volume) 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. Waste activated sludge (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.
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 with new sludge storage volume.

Flow Equalization
June 13, 2023
Under this alternative the two 25,000 gallon aeration tanks, the 9,000 gallon sludge holding tank, and the
15,400 gallon equalization tank in the existing package treatment plant would be consolidated to flow
equalization volume thus creating a total flow equalization volume of 74,400 gallons (62% of treatment
volume). The proposed flow equalization system is intended to leverage the existing 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 will be stored in 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 return
activated sludge (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 2 is
shown in Figure 3-4.
UCW requested an option for WAS to be pumped to the sludge holding tank. This would require using
RAS pumps in lieu of the standard airlift RAS conveyance provided with package plants. Section 4.1
provides an additive cost to include RAS pumps with WAS discharged using a modulating valve and flow
meter.
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 2 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 2:
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 aeration tanks, sludge holding tank, and
equalization tank to create a single equalization system.
• The existing secondary clarifiers will be demolished.

4.1 Additional Cost Considerations
In lieu of providing a package treatment plant system, the proposed aeration tanks and sludge holding
tank may be designed and constructed as concrete tanks. This will require cast -in -place concrete walls,
stainless steel air piping, and specified air diffuser grids. Additional construction cost is estimated to be
$400,000 with additional engineering services of $50,000, thereby increasing the Project Total Cost by
approximately $500,000 (for either alternative).
In lieu of providing a conventional air lift RAS system with manual WAS outlet as typically provided
with a package treatment plant system, RAS pumps with WAS control using an actuated valve and flow
meter may be designed and constructed. This will include two or three RAS pumps, ductile iron piping,
and control components. Additional construction cost is estimated to be $250,000 with additional
engineering services of $20,000, thereby increasing the Project Total Cost by approximately $300,000
(for Alternative 2).
Adding a restroom in the existing building can be evaluated and designed. Additional construction cost is
estimated to be $75,000 with additional engineering services of $20,000, thereby increasing the Project
Total Cost by approximately $100,000 (for either alternative).

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. Dimensions of field assembled
plants and pre -manufactured plants for each alternative are available in Appendix B-3. Due to the
limited available space for expansion, only the 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.
• For both alternatives, the inclusion of an outlet connection at the proposed sludge holding tank for
sludge hauling.
• 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.

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
Yt�
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 13' 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
and smaller

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.

writing by Seller.
The terms and conditions as set forth herein and our quotation or as modified by written agreement shall constitute the entire agreement (hereinafter called the "Agreement") between Seller and
Buyer. A failure by either party to enforce any rights under this Agreement shall not be deemed to constitute a waiver of those or any other rights under this Agreement. These Terms and
Conditions of Sale shall be deemed accepted by Buyer upon Seller's receipt of Purchase Order from Buyer. No condition stated by Buyer shall be binding upon Seller if in conflict with,
inconsistent with, or in addition to the Terms and Conditions of Sale, unless expressly accepted in a writing signed by Seller. In the event of conflict or differences in the terms or conditions of
Buyer's Purchase Order and the Terms and Conditions of Sale herein, the Terms and Conditions of Sale shall govern.
1. ORDERS: All orders are subject to acceptance and approval by Seller's credit department and are not binding until and unless so approved and accepted. Written acknowledgement of an
order shall constitute acceptance and will thereby be a binding contract which cannot be modified or cancelled by Buyer without written consent of Seller.
2. PRICES AND PAYMENTS: All prices are quoted and payable in U.S. dollars, unless otherwise noted. Quoted prices shall remain valid for thirty days unless written communication is received
by Seller prior to such time. Seller reserves the right to restrict or modify the terms of payment or to require payment prior to shipment if, in Seller's opinion, the Buyer's financial condition or other
circumstances do not warrant shipment on the terms originally specified in the Agreement.
Unless expressly agreed to in writing on a specific contract or order, pending satisfactory credit review, Seller standard payment terms are: (a) For orders under $100,000 the payment terms
shall be Net 30 days from date of shipment, with no retainage held. (b) For orders over $100,000 the following terms shall apply, assuming satisfactory credit review: 20 % of order value from
date of accepted purchase order. 30 % of order value upon release for production for material procurement. 50 % of order value at readiness to ship. (c) All invoices are to be paid Net 30 days.
(d) In those cases where progress payments are required, all work on the order will cease if payment is not received in accordance with the payment schedule. (a) Payment retention will not be
allowed. In the instance where an invoice is disputed, all undisputed portions remain payable within Net 30 days terms. (f) Interest at the rate of one and one-half percent (1 %%) per month or at

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.
