Project Narrative: The proposed project is to build a multi -family townhouse development in Grover, NC at the intersection of Mulberry Road, Cherry Street, and Main Street. To provide sewer services to the 29 homes, a sewer line extension is required. The sewer system has been designed to the NCDENR Minimum Design Criteria for the permitting of Gravity Sewers (Adopted by the Division of Water Quality on February 12, 1996. Updated to 15A NCAC 2T Regulations on March 2008). There are a total of 4 manholes for the extension with 456.99 LF of 8" PVC pipe. The longest run between manholes is 200.45 LF, below the maximum of 425 LF. There are no drop type manholes, with inside drops less than 30". Slopes on 8" PVC pipe are 0.5% throughout. There is uniform slope of the pipes between manholes. The proposed sewer system ties into an existing sewer manhole, which is currently part of the Town of Grover's sewer system. The homes will be 3BR homes and based off a flow of 360 gallons/day/home, the total flow will be 10,440 gallons/day. The homes will each have 4" PVC laterals at a minimum 0.8% slope.
