McGregor Wastewater Lagoons - Amherstburg, Ontario Wastewater Treatment

McGregor Wastewater Lagoons is a municipal wastewater treatment facility located in Amherstburg, Essex County, Ontario, Canada. It serves a population of approximately 2,956 residents, operating as part of the region's wastewater infrastructure. The plant's designed capacity is 1.00 million cubic meters per day. As a lagoon-based system, it provides treatment through natural processes such as sedimentation and biological degradation. Under Ontario's regulatory framework, wastewater facilities are governed by the Ontario Water Resources Act and Environmental Protection Act, with permits issued by the Ministry of the Environment, Conservation and Parks. The treated effluent is discharged into the local watershed, which ultimately drains into the Detroit River and then Lake Erie. Lake Erie is a vital freshwater resource supporting diverse aquatic life and providing drinking water for millions. The plant plays a key role in protecting this ecosystem from nutrient pollution and pathogens.

The facility discharges into the Detroit River, which flows into Lake Erie, part of the Great Lakes system. Lake Erie is ecologically sensitive due to nutrient loading and algal blooms. The plant's lagoon treatment helps reduce pollutants before discharge, supporting water quality in this important freshwater ecosystem.
