Tillsonburg WWTP - Municipal Wastewater Treatment in Tillsonburg, Ontario

Tillsonburg WWTP is a municipal wastewater treatment facility located at 31 Vienna Road in Tillsonburg, Ontario, Canada. The plant serves a population of approximately 12,343 residents in the town and surrounding area, classifying it as a medium-sized agglomeration under Canadian wastewater standards. As an operational plant in Ontario, Tillsonburg WWTP is subject to the province's stringent wastewater regulations, which align with the Canada-wide Strategy for the Management of Municipal Wastewater Effluent. For facilities serving this population range, secondary treatment is typically required, with additional nutrient removal standards applicable to discharges into sensitive water bodies. The plant's designed capacity is 1.00 million liters per day, reflecting its scale. The plant discharges treated effluent into a local watercourse that ultimately drains into the Lake Erie basin, part of the Great Lakes system. Lake Erie is ecologically significant, supporting diverse aquatic life and serving as a critical freshwater resource. The plant's operations contribute to protecting downstream water quality in this sensitive watershed.

Tillsonburg WWTP discharges into a tributary of the Thames River, which flows into Lake St. Clair and then the Detroit River before reaching Lake Erie. Lake Erie is the shallowest and most biologically productive of the Great Lakes, supporting a rich ecosystem of fish, birds, and aquatic plants. The watershed is agriculturally intensive, making nutrient management a key concern for preventing algal blooms in the lake.
