Statewide Septic Code

Michigan is the only state in the nation without a uniform code to install and inspect septic systems. As a result, over 100,000 failing septic systems in Michigan release close to 10 billion gallons of raw sewage into our soil and waterways each year, putting Michiganders’ health at risk.

An estimated 20 to 27% of the state’s septic systems are failing.

All of those failing septics are discharging billions of gallons of untreated wastewater. Human waste in our waterways feeds the growth of toxic algal blooms across our state and is known to transmit E. coli, a dangerous bacteria that can cause serious health complications. Nine thousand miles of Michigan streams have tested positive for dangerous levels of E. coli—carrying the bacteria to our favorite beaches and waterways across the state.

Our vision for change: 

Establish a statewide code and inspection system to ensure failing systems are identified and fixed before they harm human health or damage our waterways.

  • Include assistance for struggling homeowners to help them fix failing or soon-to-be-failing septics.
  • Provide funding for the administration of a statewide septic inspection program and allow for local governments to adopt more stringent standards than the state minimum if needed.
