Dearborn FAQ
Who do I call for a water-main break?
Your local city or township water department first; GLWA handles large transmission-main events through the same intake line.
Can I get my water tested for lead?
Yes, post-Flint Michigan Pure Drinking Water rules require utilities to facilitate sampling on request, often at no cost.
Detroit FAQ
Will DWSD refund a high bill from a hidden leak?
Sometimes. DWSD offers limited leak adjustments if you provide a plumber's repair receipt and the leak was underground or otherwise undetectable from inside the home.
Is my water service line lead?
Check DWSD's online inventory map at detroitmi.gov. If unknown, request a free inspection. DWSD replaces lead lines at no cost to homeowners.
