WARREN (WWJ) – Repair crews in the city of Warren were working on four separate water main breaks at once on Friday.

Mayor Jim Fouts says it’s only somewhat unusual to have so many breaks at once.

“The biggest one, a large break, occurred at 11 o’clock last night on Hoover Road, south of 9 Mile Road. The afternoon shift continued to work throughout the night and the day shift is continuing to repair this,” Fouts told WWJ Newsradio 950, late Friday morning.

“They hope to have this done by today… It was a 10-foot water main that was split.”

Police said the other breaks were at Curie Avenue and 9 Mile Road, MacArthur Boulevard and Westminister Avenue, and Dover Avenue and Racine Road.

What caused the problem?

“I was just told it was a combination of a surge coming from Detroit, and the heat,” Fouts said. “…It’s not been particularly warm, but when it heats up all of a sudden, when it’s been cold, apparently it does stress on the water main.”

Two Warren residents told WWJ that the water in his home is brown, but Fouts said the city has received no complaints.
