May 16, 2017 - ​At approximately noon on Tuesday, May 16, 2017, a sanitary sewer overflow occurred in the University of Michigan Arboretum near the entrance gate by the helipad. The overflow of an estimated 100 gallons was the result of a failed bypass pump that backed up flow into a broken sanitary sewer pipe. This overflow discharged into the Huron River. Upon notification, the city's contractor immediately installed a working pump.

In accordance with regulatory protocols, City of Ann Arbor staff contacted the Michigan Department of Environmental Quality to inform them of this unfortunate incident.
