Montross STP - Advanced Wastewater Treatment in Montross, Virginia

Montross STP is a municipal wastewater treatment facility located on Carver Street in Montross, Westmoreland County, Virginia. The plant serves a small population of 698 residents and operates with advanced treatment capabilities, reflecting its role in protecting local water quality in a coastal setting. The plant has a designed capacity of 378.54 cubic meters per day and discharges a similar volume of treated effluent. As an advanced treatment facility, it goes beyond secondary treatment standards, likely incorporating nutrient removal to address the sensitive nature of its coastal discharge environment. Under the U.S. Clean Water Act, such plants must comply with National Pollutant Discharge Elimination System (NPDES) permits issued by the Virginia Department of Environmental Quality. The treated wastewater from Montross STP ultimately drains into the Chesapeake Bay watershed, one of the largest and most ecologically significant estuaries in the United States. The bay supports diverse aquatic life, including blue crabs, oysters, and migratory fish, and is subject to rigorous nutrient reduction goals under the Chesapeake Bay Total Maximum Daily Load (TMDL) program.

Montross STP discharges into the Chesapeake Bay watershed, a vast estuary system that drains into the Atlantic Ocean. The bay is ecologically sensitive due to nutrient pollution, which can cause harmful algal blooms and hypoxic zones. The plant's advanced treatment helps reduce nitrogen and phosphorus loads, supporting the bay's recovery under the Chesapeake Bay TMDL. The surrounding area includes tidal creeks and marshes that provide critical habitat for fish and waterfowl.
