Overview
Thedford Lagoons is a secondary wastewater treatment plant in Lambton Shores, Ontario, Canada, serving 543 people. It discharges 244.00 megaliters annually and is located within 10 km of the Lake Huron coastline.
Thedford Lagoons is a municipal wastewater treatment facility located in the community of Thedford, part of Lambton Shores in Southwestern Ontario, Canada. The plant serves a small population of 543 residents and operates under Ontario's regulatory framework for wastewater systems. The plant provides secondary treatment, which is the standard level required under Canadian federal and provincial guidelines for inland and coastal communities of this size. The annual discharge volume of 244.00 megaliters reflects the scale of this small agglomeration. Treatment is achieved through lagoon-based processes typical of rural Ontario facilities. The treated effluent is discharged into the local watershed, which ultimately drains into Lake Huron, one of the Great Lakes. Lake Huron supports diverse aquatic life and provides drinking water for millions. The plant's proximity to the lake (within 10 km) underscores the importance of effective nutrient removal to protect water quality in this ecologically sensitive freshwater system.
Environmental context
Thedford Lagoons discharges into a local watercourse that flows into Lake Huron, a major Great Lake and part of the St. Lawrence River system. Lake Huron supports a diverse ecosystem including fish species such as lake trout and walleye, and provides critical habitat for migratory birds. The plant's coastal location means that treated effluent must meet strict nutrient limits to prevent eutrophication and protect the lake's water quality.
