WATERLOO REGION - Two water mains were broken by light rail transit construction crews Tuesday morning.

In both cases - and in another incident last week - nobody told workers there were pipes where they were digging, said Avril Fisken, spokesperson for Grand Linq.

Water flooded the area of Charles Street and Eby Street in Kitchener at 8:05 a.m. The same thing happened along King Street near Allen Street in Waterloo, where a water connection was broken Tuesday morning, and last week in the same area.

GrandLinq is installing light rail transit through Waterloo and Kitchener, between Conestoga Mall in Waterloo and Fairview Park Mall in Kitchener.

Workers are relocating and replacing buried utilities, including water mains along the on-street sections of the route, so the tracks don't run overtop of them.

In Kitchener, workers were attempting to connect a new water main to an existing water main, said Fiskin said.

While they were digging, soil was disturbed around an "undisclosed" water pipe, causing that rotting pipe to break, she said.

Kitchener Utilities shut off water while investigating the undocumented pipe.

Water service is expected to be restored to the area by Tuesday evening, Fisken said.

A spokesperson for Kitchener Utilities wasn't available for comment.
