As noted in the application and on the Record Drawings, this project will consist of 1784 LF of 8" PVC sewer lines,. This project is located north of Thompson Street and will connect to sewer permitted and being constructed under separate cover, (WQ0039848). The sewer proposed within this application will serve Phase 1 of Subdivision West containing 42 single family homes within this development_ The proposed project will meet all of DWR's minimum design criteria for sanitary sewer extensions. The design flow rate for this project is calculated at 7,560 gpd based on NCAC 2T Rules for wastewater flow rates and the DEQ approved sewer flow reduction of 60 gal/bedroom approved under separate cover for Chatham Park and included with this submittal package. The proposed sanitary sewer line sizes are more than adequate to convey the design flow rates.
