Napanee Water Pollution Control Plant | Greater Napanee, Ontario Wastewater Treatment

The Napanee Water Pollution Control Plant is a municipal wastewater treatment facility located at 296 Water Street West in Greater Napanee, Ontario, Canada. Serving a population of approximately 9,200, the plant is a key component of the region's water infrastructure, operating under Ontario's regulatory framework for wastewater treatment. As a plant serving a medium agglomeration, it is expected to meet secondary treatment standards under the Canada-wide Strategy for the Management of Municipal Wastewater Effluent. The plant's designed capacity of 1.00 million cubic meters per day suggests it is sized to handle current and future community needs. The treated effluent is discharged into the Napanee River, a tributary of Lake Ontario. This discharge contributes to the health of the Lake Ontario basin, which supports diverse aquatic life and provides drinking water for millions. The plant's operation is critical for protecting downstream water quality and the ecological integrity of the Great Lakes system.

The plant discharges into the Napanee River, which flows into the Bay of Quinte on Lake Ontario. Lake Ontario is the easternmost Great Lake and a vital freshwater resource. The Bay of Quinte is an ecologically sensitive area known for its fish habitat and migratory bird populations. Proper treatment is essential to prevent nutrient loading and protect the lake's ecosystem.
