King Street Wastewater Treatment Plant, Hamilton, Ontario - Municipal Wastewater Facility

The King Street Wastewater Treatment Plant is a municipal facility located in Hamilton, Ontario, Canada, serving a population of approximately 32,482 residents. Situated in the Golden Horseshoe region, the plant is part of the city's wastewater infrastructure, treating domestic sewage from the surrounding community. As a Canadian wastewater treatment plant, it operates under federal and provincial regulations, including the Canada Water Act and Ontario's Clean Water Act. For a medium-sized agglomeration serving over 30,000 people, secondary treatment is typically required to meet effluent quality standards. The plant's designed capacity of 1.00 million cubic meters per day indicates it is sized to handle current and future flows. The treated effluent is discharged into the local watershed, which ultimately drains into Lake Ontario, one of the Great Lakes. Lake Ontario supports diverse aquatic life and provides drinking water for millions. The plant plays a key role in protecting this vital freshwater resource from nutrient pollution and pathogens.

The plant discharges into the Hamilton Harbour watershed, which flows into Lake Ontario via the Burlington Ship Canal. Lake Ontario is the easternmost Great Lake and supports a complex ecosystem, including native fish species and migratory birds. The plant's operations help reduce nutrient loading and protect water quality in this ecologically sensitive area, which is part of the larger Great Lakes Basin.
