Silver Valley Regional Sewer System — Sewer Permitting Memo:
Davidson County and the City of Thomasville are currently working together to provide sewer service to
a significant area in the Silver Valley area of Davidson County. This project is known as the Silver Valley
Regional Sewer System and is intended to serve an area of the County along the Highway 64 corridor,
between Interstate 85 and NC Highway 109. A majority of this area is. not currently served with sewer,
and is considered to be a highly attractive area for future economic development, specifically industrial
development. The regional system is being built in several different phases funded by each party,
requiring permitting to be submitted for individual parts of the whole project that will eventually be
owned and maintained by the City of Thomasville. As discussed below in detail,, each of the phases will
operate independently of one another until the final project is completed, allowing the New Bowers
Road Pump Station to pump into the Nucor Sanitary Sewer Outfall extension, connecting it to the Silver
Valley Regional Sewer System. Once this final project is completed, a transfer of ownership and permit
modification application will be made to get the New Bowers Road Pump Station and associated outfall
transferred to the City of Thomasville.
The initial phase of the project began construction in the first quarter of 2024 and is known as the Nucor
Sanitary Sewer Outfall. This permit number for this project is WQ0045042 and consists of
approximately 9,111 LF of 24" gravity sewer, a 100 GPM grinder pump station, approximately 20 LF of 3"
force main, and approximately 2,120 LF of 4" force main discharging into the City ofThomasville's
existing sewer system. This project is nearing completion and will be certified for use well ahead of the
start of the next phase of construction of the regional system.
The second phase of the Silver Valley Regional Sewer System is made up of a single construction
contract, but is being submitted for permitting with three different applications. The first permit
application is known as the Nucor Sanitary Sewer Outfall. This portion of the project is intended to
extend the outfall constructed in the initial phase (WQ0045042) from it's upstream end point adjacent
to Kepley Road, north and west to US Highway 64. This project also includes the force main which will
be needed in the future to connect the existing New Bowers Road Pump Station to the outfall that is
being proposed, allowing the New Bowers Road Pump Station to pump to the regional sewer system.
The permit application for this work will include a total of 8,895 LF of 18" PVC sanitary sewer outfall, 380
LF of 18" DIP sanitary sewer outfall, 130 LF of 12" PVC sanitary sewer outfall, 210 LF of 12" DIP sanitary
sewer outfall, and 12,250 LF of 10" DIP force main. The permit application for this work will be for "No
Flow", as any new flow tributary to this outfall will be permitted separately. The force main will also be
considered "No Flow" as it will not be connected to the existing New Bowers Road Pump Station in the
current phase. of work, but will be connected after the final phase, when permitting will also be updated
to show this flow being. redirected to the City of Thomasville. The intent to is minimize costs and
environmental impacts by'installing the force main concurrently with the sanitary sewer outfall to be
installed as detailed in the third permit application for the second phase of the Silver Valley Regional
Sewer System. This permit application will be from the City of Thomasville, as the system will be
operated and maintained by the City.
The second application for the second phase of the Silver Valley Regional Sewer System is, known as the
New Bowers Road Pump Station. This permit application will be for a modification of the existing permit
number WQ0039834, upgrading the pump station from 200 GPM to 650 GPM. Original portions of the
existing permit to remain as -is include the gravity sewer, force main, and major structures at the existing
740 Chapel Hill Road, Burlington, North Carolina P.O. Box 1179 (27216)

pump station. The work being submitted as part of this permit application include replacement of the
electrical components, replacement of back-up generator, and replacement of the existing pumps as
required to increase the pump capacity of the pump station from 200 GPM to 650 GPM. The existing
permittee for this pump station and associated gravity sewer and force main is the City of Lexington, but
the physical ownership had been maintained by Davidson County. A name change request for the
existing permit has been submitted in order to show Davidson County as the permittee. The permit
application for the work described above will be from Davidson County, as they will be responsible for
the operation of the pump station until it is turned over to the City of Thomasville. Once the final phase
of the Silver Valley Regional Sewer System is completed, this pump station will be transferred to the City
of Thomasville and re -permitted, as flow will be redirected from the existing force main to the proposed
10" force main installed as part of the permit application in the above paragraph. Once this re -
permitting is complete, flow will be tributary to the City of Thomasville system, allowing additional
.development in the service area and reducing flow into the City of Lexington system.
The third application for the second phase of the Silver Valley Regional Sewer System is known as the
New Bowers Road Outfall. This outfall extends from the existing outfall installed as part of the 1-85/US
Hwy 64 Interchange Sewer Improvements project (WQ0039834) east and north, across US -Highway 64
to the Davis -Townsend Elementary School. This portion of the project is intended to provide sewer
service to the elementary school, along with providing sewer service to other areas that are not
currently served with sewer. The permit application for this work will include 2,365 LF of 12" PVC
sanitary sewer outfall, 89S LF of 12" DIP sanitary sewer outfall, 4,675 LF of 8" PVC sanitary sewer outfall,
and 1,170 LF of 8" DIP sanitary sewer outfall. The permit application for this work will be fora design
capacity of 6,000 GPD (500 students @ 12 gal/student) to serve the elementary school, which does have
a cafeteria but no gym or showers. While the intent of this outfall is to serve additional economic
development in the area, these future projects will be permitted separately. This permit application will
be from Davidson County, as they will be responsible for the maintenance of the outfall until it is turned
over to the City of Thomasville.
The final phase of the Silver Valley Regional Sewer System will include an outfall extension downstream
of WQ0045042, a new regional pump station, and force main from the pump station to the City of
Thomasville's Hamby Creek Wastewater Treatment Plant. This project will be submitted for permitting
sometime in the second quarter of 2025, with design still being completed. Once this project is
completed and in operation, the New Bowers Road Pump Station tie4n to the force main installed as
part of the first permit application in the second phase of the regional system can be completed. As part
