Assateague State Park TP - Advanced Wastewater Treatment in Franklin Heights, Maryland

Assateague State Park TP is a wastewater treatment facility located in Franklin Heights, Worcester County, Maryland, United States. The plant serves a small population of 425 people, primarily supporting the state park and nearby communities. Its location on the Atlantic coast places it in a sensitive coastal environment. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the US Clean Water Act. With a designed capacity of 113.56 m³/day and a current discharge volume of 37.85 m³/day, the facility operates well below its capacity. Under the US EPA National Pollutant Discharge Elimination System (NPDES), plants of this scale are typically permitted to discharge treated effluent into surface waters, with strict limits on nutrients and pathogens to protect coastal ecosystems. The treated effluent from Assateague State Park TP is discharged into the Atlantic Ocean via local waterways. The surrounding area includes Assateague Island, a barrier island that supports diverse aquatic life, including migratory birds and marine species. The plant's advanced treatment helps minimize nutrient loading and protects the fragile coastal environment from eutrophication and other pollution impacts.

The plant discharges into the Atlantic Ocean via coastal drainage channels on Assateague Island. The receiving waters are part of the Mid-Atlantic Bight, a productive marine ecosystem that supports fisheries, migratory birds, and marine mammals. The area is ecologically sensitive due to its barrier island geography, which is vulnerable to nutrient pollution and sea-level rise. Advanced treatment at the plant reduces the risk of harmful algal blooms and protects downstream habitats.
