Billerica Dept of Public Works Wastewater Treatment Plant, Massachusetts

The Billerica Dept of Public Works wastewater treatment plant serves the town of Billerica, Massachusetts, a community in Middlesex County. With a population served of about 27,000, the facility is part of the municipal infrastructure managing wastewater from residential and commercial sources in the area. As a US-based plant serving a medium-sized agglomeration, it operates under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) permit program. The plant's designed capacity is 1.00 million gallons per day, and it is expected to meet secondary treatment standards as required by the EPA for municipal facilities of this scale. The plant discharges treated effluent into the local watershed, which ultimately drains into the Concord River and then the Merrimack River, flowing to the Atlantic Ocean. The receiving waters support diverse aquatic life and are important for regional water quality and ecological health.

The plant's treated effluent flows into the Concord River basin, part of the larger Merrimack River watershed that drains into the Atlantic Ocean. The Concord River provides habitat for fish and wildlife, and the watershed supports recreational uses and drinking water supplies downstream. Maintaining treatment standards helps protect these ecological and community resources.
