Sewage backup discharges on street

MARQUETTE — The City of Marquette had a small sewage backup Friday morning at the corner of Seventh and Fisher streets where an estimated 10 gallons escaped onto the street but did not make it into the stormwater system.

Marquette City Public Works sewer crew cleared the line but the discharged sewage dried up in the sun and a street sweeper was used to clean up the street. The Michigan Department of Environment, Great Lakes & Energy office Marquette was also notifed.

At 9:20 a.m., Sewer Maintenance Supervisor Chad Hightshoe responded to a call about a surcharging manhole that was wet and slightly bubbling from a hole in the lid. When the sewer crew arrived at 9:35 a.m., they jetted the line and the downstream sewer main and found a blockage that consisted of rags, grease and some pieces of plastic, Hightshoe said. The last maintenance done on this line was December 2018.

“This section of main is on a two-year cycle because of the heavy flow and the pipe is contructed of reinforced plastic materical which is a very smooth surface,” Hightshoe said.
