Maynard Department of Public Works Wastewater Treatment Plant, Maynard, Massachusetts

The Maynard Department of Public Works wastewater treatment plant serves the town of Maynard, Massachusetts, a community of about 9,453 people in Middlesex County. Located at 11 Pine Hill Road, the plant is part of the town's municipal infrastructure, managing wastewater from residential and commercial sources. The plant operates under the US Clean Water Act, which requires secondary treatment for municipal wastewater. The designed capacity is 1.00 million gallons per day, indicating a facility sized for a small to medium agglomeration. Plants of this scale in Massachusetts typically employ activated sludge or similar biological treatment processes. The treated effluent is discharged to a local water body that ultimately drains into the Assabet River, a tributary of the Concord River, which flows into the Merrimack River and eventually reaches the Atlantic Ocean. The plant plays a key role in protecting the Assabet River watershed, which supports diverse aquatic life and recreational uses.

The plant discharges into a local stream that feeds the Assabet River, part of the Concord River watershed. This river system flows into the Merrimack River and then to the Atlantic Ocean. The Assabet River is ecologically sensitive, supporting fish species such as brook trout and providing habitat for freshwater mussels. The plant's operations help maintain water quality in this inland watershed, which is important for both wildlife and downstream communities.
