Erie Co SD6 Lackawanna WWTP - Buffalo, New York Wastewater Treatment

Erie Co SD6 Lackawanna WWTP is a municipal wastewater treatment facility located in Buffalo, New York, serving a population of approximately 21,242. The plant is part of Erie County's wastewater infrastructure and operates under the regulatory framework of the U.S. Clean Water Act, which requires NPDES permits for discharges to surface waters. As a medium-sized agglomeration, the plant is expected to provide secondary treatment as a minimum standard under federal regulations. The designed capacity is 1.00 million gallons per day, indicating a facility sized for its service population. Typical plants in this region employ activated sludge or similar biological treatment. The plant's treated effluent ultimately reaches Lake Erie, part of the Great Lakes system, which is a critical freshwater resource. The discharge contributes to the nutrient load in the lake, and the plant must comply with phosphorus and other limits to protect aquatic life and drinking water sources. The facility plays a key role in maintaining water quality in the Buffalo River and Lake Erie watershed.

The plant discharges into the Lake Erie basin, which drains into the Niagara River and eventually Lake Ontario. Lake Erie is the shallowest of the Great Lakes and is sensitive to nutrient pollution, particularly phosphorus, which can cause harmful algal blooms. The plant's operations are important for protecting the lake's ecosystem, which supports diverse fish populations and provides drinking water for millions.
