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 named Caldwell Townhomes, located off Farmington Ridge Parkway. The referenced project will serve 67 single-family townhomes, with a projected wastewater flow of 24,120 gallons per day (gpd). The wastewater generated by this project will be conveyed through a proposed gravity system and then enter WSACC's system at the existing 18-inch Fuda Creek Interceptor. WSACC acknowledges it has or will have capacity for wastewater from the proposed development based on information provided by Town of Harrisburg 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. The list and schedule of CIP projects are tentative and are revised periodically to reflect changing conditions and needs. If construction of this project does not commence within two (2) years of the date of this notice, the notice is rescinded and a second request and notice will be required before flow capacity is accepted. Please notify WSACC, in writing, when construction of this project is initiated. This sewer capacity allocation may also be cancelled pursuant to the conditions set forth in the WSACC Sewer Allocation and Commitment Policy. Please note that the final commitment to service to provide wastewater treatment services shall occur upon application for a building permit for the project and when system development fees are paid pursuant to N.C.G.S §162A, Article 8.
