Flooding Impacts on Septic Systems and Private Wells

Many of Michigan's residents and visitors are experiencing flooding challenges. Whether the flooding is ongoing or in the early stages of recovery, resources are available through the Michigan Department of Environment, Great Lakes, and Energy (EGLE) website. 

For information about onsite wastewater systems and flooding, please go to EGLE's Onsite Wastewater webpage. You will find the following guidance materials:

• "Frequently Asked Questions (FAQ): Septic Systems and Flooding Events

• Guidance for Septic Systems Before, During, and After a Flood" developed by the National Environmental Health Association (NEHA). Additional septic system flooding information is available directly at the NEHA webpage

Individuals seeking information about residential drinking water wells can visit EGLE's Water Well Construction webpage. There you will find water well construction fact sheets including "Protecting Your Private Water Supply In An Emergency." If you have specific questions about what water well sampling tests are appropriate for your situation, please contact your local county health department.
