A Sanitary Sewer Overflow (SSO) occurred from 11:51 p.m. May 30 to 3:21 a.m. on on May 31.

The reported discharge is from a private or municipal separate sewer collection system (not wastewater treatment plant) during wet or dry weather, or a dry weather discharge from a municipal combined sewer collection system, according to a report from the City of Manistee’s deputy director of utilities.

A SSO discharge report from the Michigan Department of Environmental Quality’s Water Resources Division indicated 1.5 inches of rain fell between 5:45 p.m. and 9:30 p.m. on May 30.

Total overflow was 230,000 gallons of diluted raw sewage into Manistee Lake.

The location of the discharge is at SSO outfall No. 18, located at the intersection of Fifth and Ramsdell streets. The reason for the discharge is hydraulic overload of collection system.
