With a population equivalent of 500, it is a small-scale municipal facility that provides secondary treatment to domestic wastewater from the town and surrounding area. As a secondary treatment plant, Monterey STP meets the minimum federal standard under the U.S. Clean Water Act for municipal wastewater treatment. The plant has a designed capacity of 302.83 cubic meters per day and currently treats an average daily flow of 227.13 cubic meters, indicating operational headroom.

The treated effluent from Monterey STP ultimately drains into the Chesapeake Bay watershed via the Potomac River system. The Chesapeake Bay is the largest estuary in the United States and an ecologically sensitive ecosystem that supports diverse aquatic life, including blue crabs, oysters, and migratory fish. Nutrient removal from small plants like Monterey STP contributes to regional efforts to reduce nitrogen and phosphorus loads to the bay.

Monterey STP discharges into local streams that flow into the Potomac River, which empties into the Chesapeake Bay. The Chesapeake Bay is a large, productive estuary that supports a complex food web and is a critical habitat for numerous species, including the Atlantic sturgeon and the bald eagle. The bay has historically suffered from eutrophication due to nutrient pollution, making effective wastewater treatment at all scales important for its restoration.
