The Detroit Water and Sewerage Department (DWSD) is a public utility that provides water and sewerage services for Detroit, Michigan and owns the assets that provide water and sewerage services to 126 other communities in seven counties. It is one of the largest water and sewer systems in the United States. In 2000, the utility utilized five water treatment plants using water from the Detroit River and Lake Huron. In mid 2014, DWSD had acquired significant debt and delinquent accounts, and talks of privatization were occurring. As of January 1, 2016, under the terms of the City of Detroit's municipal bankruptcy the Great Lakes Water Authority (GLWA) was created with a $50 million annual lease agreement to the City of Detroit for 40 years, while DWSD bifurcated to focus its services specifically on the water and sewer customers within only the city of Detroit.

The Detroit Water and Sewerage Department is a sprawling network covering 1,079 square-miles, servicing more than 40 percent of the U.S. state of Michigan's population, and employing nearly 2,000 people. DWSD is one of the most extensive and largest water and sewage systems in the United States. Along with serving the entire city of Detroit, it also serves the counties of Genesee, Oakland, Macomb, Washtenaw, Wayne, St. Clair, Lapeer and Monroe. In 2000, the network comprised 11,000 miles of water mains and a storage capacity of 363 million gallons.

In 2000, DWSD provided water for around four million customers in Detroit and its metropolitan area. At this time, the department utilized five water treatment plants that were fed from three raw water intakes, two of which were sourced from the Detroit River and one of which was sourced from Lake Huron. The water treatment plants used the technologies of "pre-chlorination, rapid mix, flocculation, sedimentation, filtration and chlorine disinfection". At this time, the five water treatment plants were Waterworks Park, Springwells, Northeast, Southwest and Lake Huron.
