Trenchless technology means the city will not have to dig up roads to replace 2.7 kilometres of sewer pipeline in need of repair.
Instead, Cured-In-Place Pipe (CIPP) will be used to repair a section of line running along Hardy Street, Enterprise Way, Enterprise Court, Parkinson Way, Sutherland Avenue, Burtch Road, and through the Parkinson Recreation Centre parking lot.
91裸聊视频淭he problem started in 2018 at a key intersection in town,91裸聊视频� explained Rod MacLean, utilities planning manager. 91裸聊视频淰ideo inspection showed that the pipe had deteriorated underneath the intersection of Sutherland Avenue and Burtch Road.91裸聊视频�
The steel reinforced pipe is 40 years old but should last 80 years, MacLean said.
91裸聊视频淲hat91裸聊视频檚 important about that one is that all the flow comes from across the highway in two areas, so we were concerned about this.91裸聊视频�
The project was stalled by COVID and then design and constructibility issues. Replacing the pipe with traditional construction would be time-consuming and more costly.
91裸聊视频淲e really didn91裸聊视频檛 want to dig under the highway if we didn91裸聊视频檛 have to,91裸聊视频� MacLean added.
CIPP technology injects material into the pipe through a manhole with it traveling in both directions.
91裸聊视频淚t91裸聊视频檚 like a balloon that gets pushed through the pipe91裸聊视频t goes in heated91裸聊视频hich finishes the cure,91裸聊视频� MacLean said. 91裸聊视频淏asically what you get is a blue PVC pipe inside except it91裸聊视频檚 a slightly different material.91裸聊视频�
CIPP is expected to last 50 to 60 years.
To insert the liner, the sewer flow will be bypassed with two overland pipes monitored 24 hours a day.
One pipe will intercept at Hardy St., redirecting along the old rail bed and then following Clement Ave., and reconnecting to existing sewer lines on Vineland St. The other pipe will begin at Burtch Rd. between Highway 97 and Sutherland Ave. and rejoin the existing sewer line at Guisachan and Byrns roads.
The $7 million project begins next week and some intermittent single-lane alternating traffic is expected during construction.
91裸聊视频淭his is the first time using this (CIPP) and it91裸聊视频檚 a real chance for us to look at this as a new option,91裸聊视频� MacLean said. 91裸聊视频淲e91裸聊视频檒l see where it goes in the future with other utility possibilities.91裸聊视频�
