Section 1 Executive Summary In 1998, the Water and Sewer Authority of Cabarrus County (WSACC) retained Camp Dresser & McKee (CDM) to prepare a 201 Facility Plan addressing the wastewater collection and treatment needs for Cabarms County. This document was prepared in March of 1998 and includes a 20-year plan for meeting the area's needs. The recommendations from this Facility Plan were included in a Capital Improvement Program (CIP) adopted by WSACC. The CIP includes interceptor, pump station, and treatment plant projects designed to meet the 20~year needs of Cabarrus County and neighboring regions. Included in this plan is a project designed to meet the needs of the Adams Creek basin. This basin is located in the eastern part of the county and contains a portion of the Town of Mt. Pleasant. Mt. Pleasant is a member utility of WSACC. The town owns and operates a wastewater collection system. Wastewater generated in the Adams Creek basin is pumped into the next drainage basin where it is collected and transported via WSACC's interceptor and pumping system and is treated at the Rocky River Regional Wastewater Treatment Plant (WWTP), owned and operated by WSACC. The Adams Creek basin also contains the growth corridor located between Mt. Pleasant and the City of Concord. The basin is expected to see substantial growth over the next 20 years. It is slated to be zoned medium-density residential per the county land use plan and is planned to receive public sewer service. Cabarrus County is seeking State Grants and State Revolving Funding for the Adams Creek interceptor. This interceptor consists of 24- and 30-inch gravity sewers with 8- and 10-inch branch sewers serving existing facilities. The project is sized to handle projected build-out flows for the entire service area. Under year 2020 conditions, the pipe will flow approximately 45 percent full. The project will eliminate three existing pump stations, two of which are over 50 years old and subject to failures and overflows. It will also eliminate the existing Mt. Pleasant High School WWTP. This is a 12,000-gpd package treatment plant that discharges into Adams Creek. The facility has had NPDES permit violations in the past. The Adams Creek interceptor compares favorably with the No Action alternative. Under the No Action alternative, the existing pumping and treatment facilities will remain on-line. In addition, the area is not suitable for individual septic systems or land application systems. Therefore, small package treatment plants would need to be implemented to serve the area. These small plants would all discharge to tributaries of Adams Creek. ODI~ Camp Dresser & McKee ~'~_ ]~ 1
