It serves a population of 1,129 residents in this rural community within Prescott and Russell Counties. The plant operates as a secondary treatment lagoon system, which is a common approach for small agglomerations in Ontario. As a secondary treatment facility, the plant provides biological treatment to reduce organic matter and suspended solids before discharge. The plant's discharge volume of 507.00 cubic meters per day reflects the scale of the community it serves. In Ontario, such facilities are regulated under the Ontario Water Resources Act and typically require Environmental Compliance Approvals from the Ministry of the Environment, Conservation and Parks. The treated effluent is discharged into local waterways that ultimately drain into the Ottawa River, a major tributary of the St. Lawrence River. The Ottawa River watershed supports diverse aquatic life and provides drinking water for millions of people downstream. The plant's operation helps protect water quality in this ecologically significant river system.

The plant discharges into local streams that flow into the Ottawa River, which then joins the St. Lawrence River near Montreal. The Ottawa River watershed is a vital ecosystem supporting fish species such as walleye, pike, and sturgeon, and provides habitat for migratory birds. The St. Lawrence River ultimately drains into the Gulf of St. Lawrence, a critical marine environment. The plant's secondary treatment helps reduce nutrient loading and protect downstream water quality.
