Patten STP - Wastewater Treatment Plant in Patten, Maine

Patten STP is a municipal wastewater treatment plant located in Patten, Maine, a small town in Penobscot County. The facility serves a population of 190, reflecting the rural character of the area. It operates under the regulatory framework of the US Clean Water Act, which governs wastewater discharges across the United States. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 113.56 cubic meters per day and a similar discharge volume, the facility is sized appropriately for the small community it serves. As a small agglomeration, it meets the typical requirements for secondary treatment under federal and state regulations. The treated effluent is discharged into local waterways that ultimately drain into the Penobscot River watershed, which flows into Penobscot Bay and the Gulf of Maine. This watershed supports diverse aquatic life and is an important ecological corridor in northern New England. The plant's operations help protect downstream water quality in this sensitive region.

Patten STP discharges into the Penobscot River watershed, which flows through central Maine before emptying into Penobscot Bay and the Gulf of Maine. This watershed supports a variety of fish species, including Atlantic salmon, and provides critical habitat for migratory birds. The plant's secondary treatment helps reduce nutrient and pollutant loads, protecting downstream ecosystems in the bay and coastal waters.
