Central Square V WWTP - Village of Central Square, New York Wastewater Treatment Plant

Central Square V WWTP is a municipal wastewater treatment facility located at 675 South Main Street in the Village of Central Square, Oswego County, New York. The plant serves a population of approximately 1,646 residents and operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal discharges. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a design capacity of 1,703.43 volume units and an average discharge volume of 707.87 volume units, the facility operates well within its capacity. As a US-based plant, it is subject to 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 treated effluent from Central Square V WWTP is discharged into a local water body that ultimately drains into the Lake Ontario basin. Lake Ontario is one of the Great Lakes and supports diverse aquatic life, including fish species such as lake trout and salmon. The plant's discharge contributes to the overall nutrient load in the watershed, and its secondary treatment helps reduce the impact on downstream ecosystems.

The plant discharges into a tributary of the Oswego River, which flows north into Lake Ontario. Lake Ontario is a large freshwater lake that supports a complex food web, including native fish populations and migratory birds. The watershed is influenced by agricultural and residential runoff, and the plant's secondary treatment helps mitigate nutrient pollution that could contribute to algal blooms in the lake.
