Septic Tank Companies in Michigan

Michigan's onsite wastewater treatment systems are regulated at the county level by local health departments, guided by the Michigan Department of Environment, Great Lakes, and Energy (EGLE) and the Michigan Criteria for Subsurface Sewage Disposal. Unlike most states, Michigan does not have a statewide septic code — instead, each of the state's 83 counties (through 45 local health departments) sets and enforces its own rules under the state's general framework. Michigan's sandy glacial soils in the northern Lower Peninsula and Upper Peninsula generally provide excellent drainage, while the heavier clay soils in the southern Lower Peninsula around Washtenaw, Lenawee, and Branch counties drain more slowly and require careful system design.
