GRAND HAVEN, MICH. – A power outage to part of the Grand Haven-area sewage treatment system led to a no-body contact advisory for a portion of the Grand River.
Between shortly after midnight until 8:30 a.m. Wednesday, about 830,000 gallons of sanitary sewage was released from the sewage treatment plant in Grand Haven.
On Wednesday morning, the Ottawa County Department of Public Health issued the advisory for the river from 1 mile east of the U.S. 31 bridge downstream to Lake Michigan. The advisory remains in effect until testing is completed, officials said.
The release occurred when the plant’s ultraviolet system, the last step of the treatment process, lost power, said Plant Superintendent David Krohn. He said the plant staff began working to correct the problem immediately after being notified of the power outage.
