The Great Lakes Water Authority (GLWA) and the Detroit Water and Sewerage Department (DWSD) want to assure Detroit residents and customers of GLWA's regional system that they are not affected by the lead and copper issues that the Detroit Public Schools Community District (DPSCD) is experiencing. Aging school infrastructure (i.e. plumbing) is the reason for the precautionary measure of providing bottled water. The treated drinking water provided by GLWA and distributed by DWSD not only meets, but surpasses all federal and state Safe Drinking Water Act regulations for quality and safety. The water at GLWA’s treatment plants is tested hourly and DWSD has no lead service lines connected to any DPSCD building. The drinking water is of unquestionable quality. GLWA and DWSD stand ready to provide any technical assistance to DPSCD.
