Water Management Systems
- All drains outside of the buildings in Dearborn flow Directly to the Rouge River without treatment.
- The 每日大赛 in conjunction with the University of Michigan has a storm water discharge permit.
- Discharges to the storm water system must be properly managed.
Sanitary Sewer
- Drains located inside buildings (sinks, floor drains, etc).
- Collects wastewater generated inside of homes, laboratories, offices, businesses, etc.
- Treated at the City of Detroit Waste Water Treatment Plant prior to discharge to the Detroit River.
Storm Sewer
- Designed to prevent flooding.
- Collects water from parking lots, roadways, etc.
- No treatment prior to discharge to the Rouge River.
- Drains along roads or in parking lots.
Combined Sewers
- Some small towns still have these systems.
- Sewage can overflow to rivers during storms.
- Campus storm drains discharge directly into the Rouge River.
- The Rouge River is a vital part of our ecosystem.
Permits & Plans
- UM has a National Pollution Discharge Elimination System (NPES) permit for storm water discharged from the campus.
- A Storm Water Management Plan (SWMP) was developed as part of the permit to regulate storm water discharges. This plan incorporates the Dearborn and Flint campuses.
- BMPs are part of the SWMP all UM campuses.
BMPs
To identify activities within the campus that have the potential to affect the quality of storm water discharges or the storm water drainage system and to assist in the development of appropriate BMPs.
Rainwater and snowmelt.
Under the storm water permit, the following can be discharged as long as best management practices are followed:
