Eden STP discharges into the Lake Michigan watershed, one of the largest freshwater systems in the world. The plant's effluent flows through local tributaries into Lake Michigan, which supports a complex ecosystem including fish, invertebrates, and migratory birds. Advanced treatment reduces phosphorus and nitrogen loads, helping to prevent eutrophication and harmful algal blooms in the lake.
