The plant serves a small population of 790 residents and operates as part of the local wastewater infrastructure in the rural upstate region. As a secondary treatment plant, Mayfield V WWTP provides biological treatment to remove organic matter and suspended solids. The plant has a designed capacity of 416.39 million gallons per day and currently treats an average daily flow of 302.83 million gallons, indicating operational headroom. Under the US Clean Water Act, such facilities must comply with National Pollutant Discharge Elimination System (NPDES) permits issued by the New York State Department of Environmental Conservation, which set effluent limits to protect water quality. The plant's treated effluent is discharged into receiving waters that ultimately drain into the Mohawk River basin and then the Hudson River, which flows into the Atlantic Ocean. This watershed supports diverse aquatic life and provides drinking water for downstream communities. The plant's secondary treatment helps reduce nutrient loads and protect the ecological health of the Mohawk-Hudson system.

Mayfield V WWTP discharges into local streams that feed the Mohawk River, a major tributary of the Hudson River. The Hudson River estuary is a critical habitat for migratory fish such as striped bass and American shad, and supports diverse aquatic ecosystems. The plant's secondary treatment helps control nutrient pollution, which is important for preventing algal blooms and maintaining oxygen levels in the downstream watershed.
