City of Ottawa Uses CIPP to Rehab Century Old Sewers
It was an environmental and traffic nightmare waiting to happen, on the heels of a sanitation nightmare that did.
Two years ago, the city’s infrastructure department set about replacing manholes along a sewer line deep beneath the west bank of the Rideau River. But a 500-metre section of the line collapsed in the Springhurst Park area south of Lees Avenue and the project was put on hold.
The city’s man in charge of replacing it, Rick Legault, says the line was made of clay. “It was beautiful workmanship,” he says of the carefully fitted square tiles, “but as brittle as a clay pot.” No wonder. It was laid down in 1899.
The collapsed line was repaired in 2009, and then it was time to consider the two kilometres of remaining century-old line.
And that was a challenge. The sewer line that needed fixing included two huge pipes across the Rideau at Strathcona Park, and shoreline pipe that went south under the Queensway, under the Transitway, and under hundreds of metres of river shore parkland.
