Flintstone Gilpin WWTP - Secondary Treatment Plant in Allegany County, Maryland

Flintstone Gilpin WWTP is a municipal wastewater treatment facility located in Allegany County, Maryland, United States. The plant serves a small population of 450 residents, providing secondary treatment to remove organic matter and suspended solids from domestic wastewater. The plant has a designed capacity of 170.34 cubic meters per day and currently treats an average daily flow of 189.27 cubic meters, indicating operation near or slightly above its design capacity. As a U.S. facility, it operates under the Clean Water Act, with National Pollutant Discharge Elimination System (NPDES) permits issued by the Maryland Department of the Environment to regulate effluent quality and protect receiving waters. The treated effluent is discharged into a local waterway within the Potomac River basin, which flows into the Chesapeake Bay. The Chesapeake Bay is a large estuary of ecological significance, supporting diverse aquatic life and important fisheries. The plant's secondary treatment helps reduce nutrient and pollutant loads to the bay, contributing to regional water quality goals.

The plant discharges into a tributary of the Potomac River, which flows into the Chesapeake Bay, the largest estuary in the United States. The Chesapeake Bay watershed is ecologically sensitive, supporting diverse aquatic species including blue crabs, oysters, and striped bass. Nutrient pollution from wastewater is a key concern, and secondary treatment helps mitigate eutrophication risks in the bay.
