Joyceville Pittsburgh Institution Wastewater Treatment Plant, Kingston, Ontario

The Joyceville Pittsburgh Institution wastewater treatment plant is located in Kingston, Ontario, Canada, serving a population of 1,023. The facility is operated by Correctional Service Canada and provides secondary treatment for the Joyceville Institution medium-security prison. The plant operates under Ontario's provincial wastewater regulations, which align with the Canada-wide standards for secondary treatment. With a population served under 10,000, it falls into the small community category, where secondary treatment is the typical requirement to protect receiving waters. The treated effluent is discharged into a watercourse that flows into the St. Lawrence River, a major waterway connecting the Great Lakes to the Atlantic Ocean. The plant's proximity to the river underscores the importance of effective treatment to safeguard aquatic life and downstream water quality in the St. Lawrence ecosystem.

The plant discharges into a tributary of the St. Lawrence River, which drains the Great Lakes basin and ultimately reaches the Atlantic Ocean. The St. Lawrence River supports diverse fish species, including sturgeon and walleye, and is a critical migratory corridor for eels and other aquatic organisms. Effective secondary treatment helps maintain water quality in this ecologically sensitive river system.
