This is in response to the Town's request for flow acceptance received July 2. 2007. 'The
Water and Sewer Authority of Cabarrus County (WSACC) has or currently expects to be able to
make available capacity at the Rocky River Regional Wastewater Treatment Plant and appropriate
sewer interceptors to transport and treat the domestic wastewater from the proposed Hawthorne
Subdivision, consisting of 104 single 'family residential lots and a clubhouse facility. The
wastewater generated by this project will be conveyed through the Town of Harrisburg's proposed
8-inch gravity system, then through a proposed on -site pump station and corresponding 8-inch force
main system (along Peach Orchard Road, Robinson (hurch, Road, and Rocky River Road), and then
enter WSACC's system at the existing I 2-inch Fuda Creek Interceptor just west of the crossing
with Hickory Ridge Road.
WSACC agrees to accept wastewater from the proposed sewer line based on information
provided by R. D. Davis Consulting Engineers, PL.L.C. (Cvil Engineer for the project) using North
Carolina Department of Environment and Natural Resources (NCDENR) wastewater flow
guidelines. The projected flow is 38,500 gpd; however WSACC expects the actual wastewater flow
to more closely approximate 26,850 gpd based upon Master Plan engineering data. The Town of
Harrisburg understands that separate Flow Acceptance Requests Will be required for the future
flows that will connect into this sewer line.
By requesting flow acceptance, the Town of Harrisburg acknowledges that WSACC may
need to upgrade, expand, or construct new facilities to accommodate the increased flow volume
granted by this and previous flow acceptance. Appropriate design and construction will be initiated
when actual flows dictate but may be subject to situations that WSACC does not expect or control.
Based upon flow of 38,500 gpd and cost of S8.1261gpd to provide treatment and transportation
capacity, this flow acceptance represents an estimated capital expenditure in excess of $31.2,85.1.
For your information and based. upon NCDENR wastewater flow guidelines, WSACC has
approved 1,586,922 gallons of flow acceptance for the Town of Harrisburg from 1992 to present
and. 38,875 gallons of flow acceptance year-to-date including this request. Based upon the
approved flow acceptances, WSACC has committed capacity valued in excess of $12,895,328 for
the Town of Harrisburg since 1992.including S315,898 for this calendar year.
Projects on the Capital Improvement Program (CIP) are subject to approval by 'WSACC's
Board of Directors, support from local governing bodies, regulatoryapproval, and funding

Subject: Hawthorne Subdivision Partial Certification #1 WQ 0032145)
M:s. Browder:
Installation of utilities for the Hawthorne project. began before I became involved. with
the project. 1 did not do the original design nor did. I witness a majority of the sanitary
sewer that is installed. 1 did not design the sewer pump station but 1 did check the
calculations after getting involved with the project and believe they are in order. I have
included the design engineer's calculations with my certification package along with the
pump drawdown test. 11 have witnessed the installation of the pump station, manholes 1-
3, and portions of the force main that required repair. I have witnessed the testing of the
sewer, force main, and pump station and certify that these items meet the State testing
standards. My certification does not include witnessing the type of pipe material, method
of installation, or any other portion of the work completed before my involvement with
the project.
Please feel free to contact me [phone] if you need additional information or want
to discuss this issue further. I appreciate your help in this matter..
