The proper disposal of solid, liquid and sewage wastes is crucial to prevent contamination to the land and the groundwater below. The use of sewers and municipal sewage treatment plants is limited to areas where infrastructure exists. On-site sewage disposal is the only viable alternative in areas not serviced by municipal sewers. Oakland County has over 80,000 onsite sewage disposal systems on residential and commercial properties.
The Environmental Health Services Unit protects land resources by offering the following services:
- Issues permits and conducts construction and final inspections for the installation of residential and non residential on-site sewage disposal systems.
- Reviews and conducts site evaluations for all of Oakland County's proposed subdivisions and site-condo projects in conjunction with the Michigan Department of Natural Resources & Environment (MDNRE).
- Assists in the licensing of septic cleaning trucks by inspecting and make recommendations to MDNRE.
