Winebrenner WWTP - Advanced Wastewater Treatment in Highfield Cascade, Maryland

Winebrenner WWTP is an advanced wastewater treatment plant located in Highfield Cascade, Washington County, Maryland, United States. The facility serves a population of approximately 3,157 residents, reflecting a small to medium-sized agglomeration typical of rural communities 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 3,785.40 volume units and a daily discharge volume of 522.39 units, the plant operates well below its capacity, indicating room for future growth. As a US facility, it operates under the Clean Water Act, with National Pollutant Discharge Elimination System (NPDES) permits issued by the Maryland Department of the Environment. The treated effluent is discharged into local waterways that ultimately drain into the Potomac River watershed and the Chesapeake Bay. The Chesapeake Bay is a vital estuary that supports diverse aquatic life, including blue crabs, oysters, and migratory fish. Advanced treatment at this plant helps reduce nutrient loads, contributing to the restoration of the bay's health.

The plant's discharge enters streams within the Potomac River basin, which flows into the Chesapeake Bay, the largest estuary in the United States. The bay is ecologically sensitive due to nutrient pollution that causes algal blooms and hypoxic zones. Advanced treatment at Winebrenner WWTP helps mitigate these impacts by reducing nitrogen and phosphorus loads, supporting the recovery of submerged aquatic vegetation and shellfish habitats.
