Water service was restored Monday afternoon to more than 50 Woodbury homes and businesses that were without water after nine main breaks late Saturday, officials said. Residents were told that water is safe to drink following the breaks.

The breaks, which were scattered across the city, were likely caused by unusually high pressure overwhelming the city's water system. All nine breaks had been repaired by Monday afternoon, according to a city news release.

Traffic was affected for most of the day.

"That means westbound Lake Road will continue to be closed through the Tuesday morning rush hour. Westbound traffic on Lake Road will be detoured away from the area via Woodlane Drive," the release said. "Motorists are encouraged to use alternate routes. Surrounding streets will be open to local traffic only."

Officials had previously reported that there had been five ruptures.

"We did have a situation where the city system had an abnormally high water pressure, because of the failure of the control system," said Klayton Eckles, Woodbury's public works director. The breaks, he said, likely resulted from "a malfunction in our control system and alarm system."

About 50 homes, an apartment complex and "about half a dozen" businesses were without water for most of the day Saturday and into Monday morning, Eckles said. Early Saturday morning, about 33 people, including 15 children, were evacuated from the apartment building, at the 300 block of Lake View Drive, after a ruptured main sent water gushing into the building.
