The subdivision is proposed to contain 99 single-family three -bedroom residential lots; each with the NCDEQ-approved flow reduction allocation of 210 gallons per day (gpd). The total daily design flow is 20,790 gallons per day (gpd). The subdivision will be serviced by a proposed gravity sewer system and one centralized pump station that will discharge sewer into an existing Brunswick Regional Water and Sewer (H2GO) sewer force main line located on the south side of Goodman Road (SR 1414). The proposed pump station is designed to service all the residential lots at 210 GPD. Due the sewer force main tie-in pressures, the proposed pump station has capacity for additional flow. However, that additional capacity is not being applied for as part of this application. Included with this submittal are provided below. The application fee was submitted with the original submittal. • B. Cover Letter (This Sheet) • C. Application Fee ($480.00) • D. Fast Track Application (Form: FTA 04-16) • E.
