ACCIDENT WWTP - Advanced Wastewater Treatment in Accident, Maryland

ACCIDENT WWTP is a municipal wastewater treatment plant located in Accident, Garrett County, Maryland, United States. The facility serves a small population of 365 residents, reflecting its role in a rural community in the Appalachian region. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 567.81 units and an average discharge volume of 439.11 units, the plant operates below its capacity. Under the US Clean Water Act, such facilities must comply with National Pollutant Discharge Elimination System (NPDES) permits, which set effluent limits to protect water quality. The treated effluent is discharged into local waterways that ultimately drain into the Youghiogheny River, a tributary of the Monongahela River, which flows into the Ohio River and then the Mississippi River to the Gulf of Mexico. The plant's advanced treatment helps protect the sensitive aquatic ecosystems of these rivers, supporting biodiversity and water quality downstream.

The plant discharges into streams that feed the Youghiogheny River, part of the Mississippi River basin. This watershed supports diverse aquatic life, including fish species such as smallmouth bass and trout. The advanced treatment reduces nutrient loading, which helps prevent eutrophication in downstream reservoirs and the Gulf of Mexico.
