Glen Walter WWTP - Secondary Wastewater Treatment in South Glengarry, Ontario

Glen Walter WWTP is a municipal wastewater treatment facility located in South Glengarry, Ontario, Canada. Serving a population of approximately 1,350 residents, the plant provides secondary treatment to manage domestic wastewater from the Glen Walter community. It operates under Ontario's regulatory framework for wastewater systems, which aligns with the Canada-wide standards for effluent quality. The plant employs secondary treatment processes, which involve biological treatment to reduce organic matter and suspended solids. With a daily discharge volume of 606 cubic meters, the facility meets provincial requirements for effluent quality. As a small-scale plant, it is subject to monitoring and reporting obligations under the Ontario Water Resources Act and the Environmental Protection Act. The treated effluent is discharged into a local watercourse that eventually drains into the St. Lawrence River, a major waterway connecting the Great Lakes to the Atlantic Ocean. The plant plays a key role in protecting downstream aquatic ecosystems and ensuring the health of the St. Lawrence River watershed.

The treated effluent from Glen Walter WWTP enters a local tributary that flows into the St. Lawrence River, one of the largest rivers in North America. The St. Lawrence River supports diverse aquatic life, including fish species such as sturgeon and walleye, and serves as a critical migratory corridor for eels and other species. The plant's secondary treatment helps reduce nutrient loading and protect water quality in this ecologically significant river system.
