The treated effluent from the plant is discharged into the local watershed, which ultimately drains into Lake Huron via the Maitland River system. This connection to the Great Lakes basin underscores the plant's role in safeguarding downstream aquatic ecosystems and drinking water sources. The facility contributes to the protection of the Lake Huron watershed, a vital freshwater resource supporting diverse fish and wildlife.

The plant discharges into the local watershed, which flows into the Maitland River and eventually reaches Lake Huron, part of the Great Lakes system. This region supports diverse aquatic life, including cold-water fish species, and is an important ecological corridor. Protecting water quality in this basin is critical for maintaining the health of Lake Huron's nearshore habitats and downstream communities.
