Ipswich Dept of Public Works Wastewater Treatment Plant, Ipswich, Massachusetts

The Ipswich Dept of Public Works wastewater treatment plant serves the town of Ipswich, Massachusetts, a coastal community in Essex County. With a population served of 4,576, it is classified as a small-scale municipal facility. The plant is located at 20 Fowlers Lane, Ipswich, and is part of the town's public works infrastructure. As a US facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting, typically administered by the Massachusetts Department of Environmental Protection. The designed capacity of 1.00 million gallons per day indicates the plant's scale. The plant discharges treated wastewater into the local watershed, which ultimately drains to the Atlantic Ocean via the Ipswich River and Plum Island Sound. This coastal environment supports diverse aquatic life, including anadromous fish runs and salt marsh ecosystems. The plant's proximity to the coast (within 50 km) underscores the importance of effective treatment to protect downstream estuarine and marine habitats.

The plant's treated effluent enters the Ipswich River watershed, which flows through the Great Marsh, one of the largest salt marsh systems in New England, before reaching Plum Island Sound and the Atlantic Ocean. This estuarine environment supports critical habitats for migratory birds, shellfish, and finfish, making nutrient and pathogen removal essential for ecological health.
