We deliver some of the world’s cleanest, safest drinking water.

The Detroit Water and Sewerage Department (DWSD) delivers clean water and collects sanitary sewage and stormwater from more than 230,000 accounts, representing a residential population of nearly 700,000. DWSD’s water system consists of more than 2,700 miles of water main and 29,000-plus fire hydrants, and the combined sewer collection system has nearly 3,000 miles of sewer piping, more than 90,000 catch basins and 16 green stormwater infrastructure projects within the city of Detroit. Since June 2019, DWSD has committed $100 million per year to begin to address the aging infrastructure, including replacing lead service lines.
