How does water get to my home?

Water is supplied to your home from either a public water supply or a private well. It’s important to determine how your water is supplied in order to understand how your water quality is monitored and who to contact if you have water quality concerns.

A general rule to follow is if you get a bill for your water, you are likely on a community water supply.

Once you’ve determine how water is supplied to your home then you can contact the appropriate agency if you have water quality questions or concerns. Feel free to reach out to EGLE if you experience issues resolving your concern with your local water supplier at EGLE-CleanWater@Michigan.gov

Community Water Supplies

Residents who receive their water from a community water supplier, should contact the agency listed on your water bill with water quality questions or concerns. View a list of community water supplies on the Michigan.gov/CommunityWaterSupply page, where you can also learn more about Michigan’s Safe Drinking Water Act and how the community water supply program helps protect over 1,400 community public water supplies in Michigan.
