London Grove WWTP and Spray Fields - Kennett Square, Pennsylvania Wastewater Treatment

London Grove WWTP and Spray Fields is a municipal wastewater treatment facility located in Kennett Square, Chester County, Pennsylvania. The plant serves a population of approximately 2,430 residents and operates under the regulatory framework of the U.S. Clean Water Act, which governs wastewater discharges through National Pollutant Discharge Elimination System (NPDES) permits issued by the Pennsylvania Department of Environmental Protection. The plant provides secondary treatment, a standard level required for most municipal facilities in the United States. Its designed capacity is 1,324.89 thousand gallons per day, with an average daily discharge volume of 919.86 thousand gallons. The treatment process includes spray fields for land application, which is a common method for small to medium-sized communities in rural areas. The treated effluent is discharged into local streams that ultimately flow into the Delaware River Basin, a major watershed supporting diverse aquatic life and providing drinking water for millions. The plant's operations help protect downstream water quality in the Chesapeake Bay watershed, as the Delaware River drains into Delaware Bay and the Atlantic Ocean.

The plant discharges into tributaries of the Delaware River, which flows into Delaware Bay and the Atlantic Ocean. The Delaware River Basin supports a variety of fish species, including American shad and striped bass, and is an important migratory corridor for birds. The spray field application reduces direct nutrient loading to surface waters, helping to protect downstream ecosystems.
