As the COVID-19 situation continues to evolve, Buffalo Sewer has reduced our onsite workforce to help flatten the curve, transitioning to a partial remote work status. We have prepared for this to minimize disruptions. Our top priority remains to protect public health by providing the critical service of clean and safe water.


Buffalo Sewer is a New York State public benefit corporation created in 1935 to “relieve the Niagara River, Buffalo River, and Lake Erie from pollution by the sewage and waste of the city and relieving city from inadequate sanitary and stormwater drainage and for the sanitary disposal or treatment of the sewage thereof.” Buffalo Sewer may accept, treat and dispose of the sewage and waste of all municipal corporations in Erie County.
