The Great Lakes Water Authority (GLWA) is a regional water and wastewater authority that provides water of unquestionable quality to nearly 40 percent of the state of Michigan, and safe and sanitary wastewater services to nearly 30 percent of the state.

On June 12, 2015, history was made as the GLWA and the city of Detroit entered into 40-year leases providing for GLWA’s operation of the regional water and wastewater system.  On January 1, 2016, GLWA began regional operations.  GLWA is an important example of regional collaboration in southeast Michigan, with the city of Detroit, the counties of Wayne, Oakland, and Macomb, and the state of Michigan uniting to ensure that both city and suburban water and wastewater member partners have a powerful, collaborative voice in the direction of one of largest water and wastewater utilities in the United States.

With the stand-up of the new authority, GLWA assumed operational, infrastructure improvements, environmental compliance and budget-setting responsibilities for the regional water and sewage treatment plants, major water transmission mains and sewage interceptors, and related facilities. These facilities are leased from the city of Detroit for an allocation of $50 million per year to fund capital improvements for the city of Detroit retail system and/or Detroit’s share of capital improvements to the regional system.

GLWA distributes finished drinking water to 88 member partners across 112 communities in eight southeast Michigan counties, which is equivalent to 3.8 million people. Wastewater conveyance and treatment services are provided to the city of Detroit and 19 member partners across 78 communities, which is equivalent to 2.8 million people.

In keeping with the spirit of collaboration from which GLWA was created, the Authority is governed by a Board of Directors that includes one representative each from Oakland, Macomb and Wayne counties as well as two representatives from the city of Detroit, and one appointed by the Governor of the State of Michigan to represent member partner communities outside the tri-county area.
