Ann Arbor Reports Sanitary Sewer Overflow

The city of Ann Arbor has reported that on the morning of Sept. 16, 2013, “an obstruction of grease and oil caused an 8-inch sanitary sewer line to back up, spilling approximately 100 gallons of raw sewage out of a manhole cover on Pauline Boulevard and into an inlet to the city’s stormwater system.”

According to the city’s press release, a member of the city’s solid waste field services team reported water leaking from a manhole cover on Pauline Boulevard at 10:15 a.m. The 8-inch sanitary sewer line was unclogged by 10:30 a.m. Nearby stormwater catch basins were vacuumed to remove any potential polluted water and sediments, according to the press release, and the incident was reported to the Michigan Dept. of Environmental Quality.

It’s the second similar incident in the last two weeks. A sanitary overflow resulted in a discharge into the Huron River on Aug. 29, 2013.
