Project Name: Grantham Subdivision Phases 3-4
Subject: Fast Track Sewer System Application Summary
Phase 3-4 of Grantham Subdivision consist of 117 single-family lots with a typical layout
of 3 bedrooms. With a daily discharge of 360 GPD for each home, the calculated maximum flow
for Phases 3-4 of Grantham is approximately 42,120 GPD.
The entire subdivision is adjacent to Robinson Church Rd. (S.R. 1168) and Reedy Creek.
The sewer network from phase 3-4 will tie-in to a manhole that was constructed in phase 1-2.
The outfall of the existing sewer network ties -in to the Reedy Creek Interceptor near manhole
#019096.

Subject: Flow Acceptance Request - Town of Harrisburg
Grantham Subdivision Phases 3-4
Dear Mr. Brigman:
This is an approval of the flow acceptance request received by the Water and Sewer Authority of Cabarrus
County (WSACC) from the Town of Harrisburg on June 27, 2018. WSACC has or will have capacity at the
Rocky River Regional Wastewater Treatment Plant and appropriate sewer interceptors to transport and treat the
domestic wastewater from the proposed project entitled Grantham Subdivision Phases 3-4, located near Robinson
Church Road in Harrisburg. The referenced project includes a subdivision expansion with 117 three-bedroom
single-family homes, with 42,120 gallons per day (gpd) wastewater flow projected.
The wastewater generated by this project will be conveyed through a proposed gravity system, through the
existing Town of Harrisburg gravity system, and then enter WSACC's system at the existing 36 -inch Reedy
Creek Interceptor. WSACC agrees to accept wastewater from the proposed development based on information
provided by Latham -Walters Engineering, Inc. (Civil Engineer for the project) using North Carolina Department
of Environmental Quality (NCDEQ) wastewater flow guidelines.
The WSACC Capital Improvement Program (CIP) has been on pay as you go since Fiscal Year 2005 — 2006,
funding Capital Projects entirely from Capital Reserves, and WSACC expects to continue this policy into the
future. Projects on the CIP are subject to approval by WSACC's Board of Directors, support from local
governing bodies, regulatory approval, and funding availability. It should be noted that the list and schedule of
CIP projects are tentative and are revised periodically to reflect changing conditions and needs.
If construction of this project is not started within two (2) years of the date of this approval, the approval is
rescinded and a second request and approval will be required. Please notify WSACC, in writing, when
construction of this project is initiated.
If you have any questions, please call me at [phone], extension 228.
Sincerely,
