Sewer Collection System

Like it has since it's inception in 1938, the Buffalo Sewer Authority has successfully safeguarded the public health and protected the Niagara River and other tributary streams from pollution by collecting and treating sewage generated by the City of Buffalo . The Authority also treated wastewater from all or parts of 11 municipalities in Western New York including Alden, Cheektowaga, Depew, Elma, Lancaster, Sloan, Tonawanda, and West Seneca.

The Authority maintains a combined sewer system of approximately 850 miles in length with 10 outlying pump stations, including a 17 million gallon capacity storm retention basin. The Bird Island Wastewater Treatment Plant (WWTP) the second largest wastewater treatment plant in New York State, treated and disposed of an average sewer flow of nearly 150 million gallons per day (MGD), including our current contracts from outside districts which bring in more than 30 million gallons per day.
