Michigan Criteria for On-site Wastewater

The state of Michigan’s DEQ (Department of Environmental Quality) has unveiled a new guidance document for septic systems in Michigan.  This document, entitled, “Michigan Criteria for On-Site Wastewater Treatment” was released on 12/21/11.  This document is intended as a guidance document for health departments working with subsurface soil-based dispersal systems up to 20,000 gallons per day.

The one thing that really caught my eye was the document’s acknowledgment and encouragement of the use of secondary treatment.  Now, systems with effluent treated below 30 mg/L BOD are sized using tailored loading rates that allow the system’s size to be greatly reduced.
