Mexico V STP - Secondary Wastewater Treatment Plant in Village of Mexico, New York

Mexico V STP is a municipal wastewater treatment plant located at 97 Academy Street in the Village of Mexico, Oswego County, New York. The plant serves a population of approximately 1,572 residents and operates as part of the region's water infrastructure. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal facilities. With a designed capacity of 1,135,620 gallons per day and an average discharge volume of 987,990 gallons per day, the plant operates at about 87% capacity, indicating efficient utilization. Treated effluent from the plant ultimately reaches Lake Ontario, a major Great Lake that supports diverse aquatic life and serves as a critical freshwater resource. The plant's proximity to the coast underscores the importance of effective treatment to protect the lake's water quality and ecosystem.

The plant discharges into the Lake Ontario watershed, which drains into the St. Lawrence River and eventually the Atlantic Ocean. Lake Ontario is a vital freshwater ecosystem supporting fish populations and migratory birds. The plant's coastal location requires careful management to prevent nutrient loading and protect nearshore habitats.
