The lift station will receive and pump sewage flow generated from the north Middle School. The design volume of waste from the school, based on 700 students and using 15 gallons per student per day, will be approximately 10,500 gallons per day (gpd) or 7.2 gallons per minutes (gpm). The LMAC WWTP shall also accept domestic waste from WestPoint Stevens. WestPoint Stevens generates flows, based on 1900 employees, of approximately 48,000 gpd or 33 gpm. The combined flow from these two entities will be approximately 58,500 gpd per 41 gpm. LMAC WWTP has the capacity to his volume of additional flow.
