The City of Hamilton has now determined what happened with the water supply in the East End over the weekend.
The Hamilton Spectator reports a “freak” series of events lead to 10 watermain bursts Saturday morning.
The city says it started with a power surge that stopped the pumping of water up the mountain.
Water Director Andrew Grice tells the Spectator once that happens gravity takes over and the water goes back to the plant.
The surprise volume of water caused the breaks in the area round the treatment facility, including along Woodward Avenue, Queenston Road, Parkdale Avenue and as far east as Dewitt Road.
Grice says the problem required the city to pay for emergency contractors to join the four in-house construction teams in an effort to fix the breaks as quickly as possible.
