The Water/Wastewater department operates two plants; one that filters drinking water and another that treats wastewater, sewage and storm water.

The Water Filtration Plant, located on Lakeshore Boulevard, produces an average of 3 million gallons of pure Lake Superior water a day in its modern, state-of-the art facilities. The plant has the capacity to produce over 7 million gallons of water per day. In addition, the plant’s laboratory tests the water in all public swimming pools and hot tubs, including hotels and schools, as well as ensuring that the water at public beaches is safe for swimming.
