Onsite Well and Septic Systems

In areas where municipal water and sewer services are not available, homeowners must rely on well and sewage (septic) systems to meet their needs. In fact, more than 2.6 million Michigan citizens use water from private drinking water wells, and over 1.2 million Michigan homes have onsite sewage systems.
