The plant discharges into local streams that flow into the Fox River, which empties into Green Bay on Lake Michigan. This watershed supports a variety of fish species and is an important migratory corridor for birds. Advanced treatment at the plant helps reduce nutrient loading, protecting the bay from algal blooms and maintaining water quality for downstream ecosystems.
