• DWSD's water supply system is one of the largest in the nation both in terms of water produced and population served. The water system draws fresh water from the Great Lakes System, with Lake Huron to the north and the Detroit River to the south. Hardness levels for treated drinking water vary depending on the time of the year, averaging 105 parts per million or 6.0 grains per gallon. DWSD's water network consists of 3,438 miles of transmission and distribution mains within the City of Detroit, and 402 miles of transmission mains in the remaining service area. DWSD's five water treatment plants pump an average of 610 million gallons of clean drinking water each day. The Department is responsible for maintenance and repair of 27,244 fire hydrants in the city. • DWSD provides water service to the entire city of Detroit and neighboring southeastern Michigan communities throughout Wayne, Oakland, Macomb, St. Clair, Lapeer, Genesee, Washtenaw and Monroe counties. The 1,079-square-mile water service area, which includes Detroit and 127 suburban communities, makes up approximately 40 percent of the state's population. Wastewater service is also provided to a 946-square-mile area that encompasses Detroit and 76 neighboring communities.
