The plant's advanced treatment helps protect this sensitive ecosystem from nutrient pollution and other contaminants.

Cumberland WWTP discharges into a local stream that flows into the St. Croix River, a major tributary of the Mississippi River. The St. Croix River is ecologically significant, supporting diverse fish populations and serving as a migratory corridor for birds. The plant's advanced treatment reduces nutrient loads, helping to prevent eutrophication in downstream waters, including Lake St. Croix and the Mississippi River.
