Crown Point T STP and On Site Sys - Town of Crown Point, New York Wastewater Treatment Plant

Crown Point T STP and On Site Sys is a municipal wastewater treatment facility located on Monitor Bay Road in the Town of Crown Point, Essex County, New York. The plant serves a small population of 300 residents and operates under secondary treatment standards, which is typical for small communities in the United States. The plant has a designed capacity of 124.92 megaliters per year and discharges approximately 113.56 megaliters annually. As a secondary treatment facility, it meets the minimum requirements of the US Clean Water Act for municipal wastewater treatment, which mandates secondary treatment for all publicly owned treatment works. The plant is likely regulated under the National Pollutant Discharge Elimination System (NPDES) permit program administered by the New York State Department of Environmental Conservation. The plant's discharge enters the Lake Champlain watershed, a major freshwater lake that drains northward into the Richelieu River and ultimately into the St. Lawrence River. Lake Champlain is an ecologically significant water body that supports diverse aquatic life and provides drinking water for many communities. The plant's proximity to the lake (within 10 km of the coast) underscores the importance of effective treatment to protect water quality.

The plant discharges into the Lake Champlain basin, which drains via the Richelieu River to the St. Lawrence River and the Atlantic Ocean. Lake Champlain is a large freshwater lake that supports diverse fish populations, including lake trout and landlocked Atlantic salmon, and serves as a critical habitat for migratory birds. The lake is sensitive to nutrient pollution, making secondary treatment important for controlling phosphorus and nitrogen loads.
