Michigan lacks statewide standards for septic systems, resulting in thousands of failing systems that can release untreated sewage, contaminating groundwater and posing risks to the environment and public health.

Michigan has an estimated 1.3 million septic systems.  Around 25% of those systems are failing, releasing untreated wastewater that can contaminate groundwater and surface water with harmful pathogens like E. coli. Homeowners can help protect their systems by having tanks inspected and pumped regularly, conserving water to prevent overload, and avoiding flushing harmful materials like wipes, grease, or chemicals.
