Water and Sewerage Department
We deliver some of the world’s cleanest, safest drinking water.
The Detroit Water and Sewerage Department (DWSD) serves more than 230,000 accounts that includes a residential population of nearly 700,000. DWSD’s water system consists of more than 2,700 miles of water main and 30,000-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. Beginning in June 2019, DWSD embarked on a five-year, $500 million program to begin to address the aging infrastructure, including replacing lead service lines.
