McKean Boro STP - Advanced Wastewater Treatment in McKean, Pennsylvania

The McKean Boro STP is a wastewater treatment facility located in McKean, Pennsylvania, serving a small population of 351 residents. The plant is situated near Lake Erie, within 10 km of the coast, and operates under the regulatory framework of the US Clean Water Act. The plant provides advanced treatment, which goes beyond the secondary treatment standard required by the US EPA for municipal wastewater. With a designed capacity of 306.62 million gallons per year and an actual discharge volume of 151.42 million gallons per year, the facility operates below its capacity, indicating room for future growth or seasonal variations. The treated effluent from the plant ultimately drains into Lake Erie, part of the Great Lakes system. Lake Erie is a vital freshwater resource that supports diverse aquatic life and provides drinking water for millions. The plant's advanced treatment helps protect this sensitive ecosystem from nutrient pollution and other contaminants.

The plant discharges into the Lake Erie watershed, which drains into the Great Lakes system and eventually the St. Lawrence River and Atlantic Ocean. Lake Erie is the shallowest and most biologically productive of the Great Lakes, supporting a rich fishery and serving as a critical migratory corridor for birds. The advanced treatment at this plant helps reduce nutrient loading, which is a key concern for preventing harmful algal blooms in the lake.
