Our Septic System Education program is designed to provide Michigan residents with educational resources regarding the essential maintenance of these septic systems to safeguard the health of their families, the environment, and their investments in these critical treatment systems.
Wastewater is the water generated from toilets, bathing, drinking/cooking, and laundry/dishwashing. Commonly in Michigan, households depend on onsite sewage treatment options, also known as a septic or onsite wastewater treatment systems, to process this wastewater. There are more than 1.2 million septic systems in Michigan with an average of 300-400 gallons of sewage being generated daily by each system. This means onsite systems in Michigan must treat and dispose of more than 360 million gallons of sewage each day.
Check out our homeowners resource page for a list of education tools to assist with managing wastewater on residential properties.
