The sinkhole at Avonhurst Drive and Elphinstone Street may be closed up and fixed, but more construction could be coming to that area this year.
The sinkhole opened up on Canada Day thanks to a damaged sewer trunk.
Pat Wilson, director of water, waste and environmental services with the City of Regina, said it was a tough job.
“Even getting it cleared of debris and dry so that we could get down and see what the circumstances were and what the repair needed to be was a considerable exercise,” Wilson said Wednesday.
“We needed to bring in additional pumping capacity. The pumps we had in-house were not large enough, so we brought in a contractor to do some of that work.”
But while the crews were in the 25-foot-deep hole, they also put a camera down the pipe and found damage to the lining in an extended distance of pipe. Wilson said it’s not clear whether that was the cause of the break in the pipe.
The sewer and storm line pipes in the hole were repaired and the hole filled with fill-crete and paved over by the end of Monday.
However, the damage to the pipe is being evaluated by the city’s engineering branch to see how bad it is. Wilson said she anticipates city crews will be sent out to fix that length of pipe later this year.
“We do look at if there’s a risk of further problems or failures, then absolutely we prioritize that work,” Wilson said.
The pipe in that area was scheduled to be checked next year, so that damage would have been found sooner or later. The pipe will still be checked next year, but the damaged section will be advanced to this year.
Wilson said it’s still not clear how much the sinkhole cost the city. She said a water main repair could cost between $10,000 and $15,000, but that could be completed in a day, She expects the cost of this repair to be substantially higher.
