The plant supports a population of approximately 16,796 residents and is situated near the northern shore of Lake Ontario. As a Canadian facility, the plant operates under provincial regulations administered by the Ontario Ministry of the Environment, Conservation and Parks.

The plant's designed capacity is 1.00 million liters per day, indicating it is sized for the community's needs. The treated effluent from the plant is discharged into the Lake Ontario watershed, which is part of the Great Lakes Basin. Lake Ontario supports diverse aquatic life and provides drinking water for millions of people. The plant plays a key role in protecting this vital freshwater resource from nutrient and pathogen pollution.

The plant discharges into the Lake Ontario watershed, which drains into the St. Lawrence River and eventually the Atlantic Ocean. Lake Ontario is a critical freshwater ecosystem supporting fish species such as lake trout and salmon, and it serves as a major drinking water source. Protecting water quality in this basin is essential for both ecological health and human use.
