Biosolids & Industrial Pretreatment

  • Michigan Biosolids & Industrial Pretreatment Program Overview

    To further preserve and protect Michigan's water resources, the Michigan Department of Environmental Quality encourages and enforces the use of wastewater treatment systems through the use of Biosolids and the Industrial Pretreatment Program.

The DEQ encourages the use of Biosolids (also known as sewage sludge) to enhance agricultural and silvicultural production in Michigan.
The goal of the Industrial Pretreatment program is to protect, preserve and improve the surface water quality of Michigan through the implementation of Federal and State rules designed to limit pollution from industrial discharges to publicly owned wastewater treatment facilities.
