Community Water Supply

The Community Water Supply Program oversees the primary EPA program that sets forth minimum standards for safe drinking water as well as administering the requirements of Michigan's Safe Drinking Water Act. The program's primary function is regulatory oversight of approximately 1,400 community public water supplies in Michigan.


The Michigan Environmental Health and Drinking Water Information System (MiEHDWIS) is a multi-year project to modernize many of Drinking Water and Environmental Health Division's existing permitting, licensing, and compliance information systems into one web-based application.

The goal of MiEHDWIS is to streamline communication between Michigan's public drinking water supplies and EGLE, increase data transparency, and facilitate collaboration between EGLE and local health department staff supporting environmental health programs. Many MiEHDWIS features are still being developed and will eventually be available to regulated entities (campgrounds, public swimming pools, public water supplies, etc.), for permit application, license renewals and uploading reports and documentation.
