Georgetown STP Wastewater Treatment Plant, Delaware | US Clean Water Act

Georgetown STP is a municipal wastewater treatment facility located in Georgetown, Delaware, serving a population of approximately 8,200. The plant is situated in Sussex County, near the Atlantic coastal plain, and plays a key role in managing local wastewater for this inland community. As a US-based plant serving a small agglomeration, Georgetown STP is subject to the Clean Water Act and National Pollutant Discharge Elimination System (NPDES) permitting. Facilities of this scale typically employ secondary treatment to meet federal and state water quality standards. The designed capacity is reported at 1.00 million gallons per day, indicating a modest infrastructure footprint. The plant discharges treated effluent into local waterways that ultimately drain to the Atlantic Ocean via the Delaware Bay and Inland Bays system. The surrounding watershed supports diverse aquatic life and is part of a regionally important estuarine ecosystem. Proper treatment at this facility helps protect downstream water quality and ecological health.

Georgetown STP discharges into the Nanticoke River watershed, which flows into the Delaware Bay and then the Atlantic Ocean. The receiving waters support a mix of freshwater and estuarine habitats, including tidal marshes and wetlands that provide critical nursery grounds for fish and shellfish. The region's flat coastal plain and agricultural land use make nutrient management a key concern for downstream water quality.
