Richmond WWTF - Secondary Wastewater Treatment Plant in Richmond, Maine

Richmond WWTF is a municipal wastewater treatment facility located at 16 Water Street in Richmond, Maine, a small town in Sagadahoc County. The plant serves a population of approximately 1,400 residents, reflecting its role in a small community along the Kennebec River region. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal wastewater facilities. With a designed capacity of 1,211.33 units and a current discharge volume of 492.10 units, the plant operates below its capacity, indicating room for future growth or seasonal variability. The treated effluent is discharged into a local water body that ultimately drains into the Kennebec River and then into the Gulf of Maine. This coastal watershed supports diverse aquatic life, including migratory fish species, and the plant's treatment performance is critical to maintaining water quality in the downstream estuary.

The plant discharges into a tributary of the Kennebec River, which flows into the Gulf of Maine, a productive marine ecosystem. The Kennebec River estuary supports important fisheries, including Atlantic salmon and striped bass, and is a key migratory corridor for diadromous fish. Maintaining secondary treatment standards helps protect these downstream habitats from nutrient and pathogen pollution.
