YORKTON - The City of Yorkton will be undertaking an new initiative to rehabilitate at least some of its sewer lines.
At its regular meeting of Council Monday a tender and associated costs was approved for $472,293 to reline two sections of sewer lines.
“The City plans to reline 914 meters of sewer pipe,” said Aron Hershmiller – Director of Public Works with the city at the Monday meeting.
Circlebrooke Drive will have 587 meters of 300mm pipe relined while McBurney drive will have 327 meters of 200 mm pipe relined.
The project will use a lining technique.
“A cured-in-place pipe (CIPP) is a trenchless rehabilitation method used to repair existing pipelines. It is a jointless, seamless pipe lining within the existing pipe and is one of the most widely used rehabilitation methods,” explained Hershmiller.
Cured in place pipe relining of sewer piping involves the management of the sewage which could be by isolating, plugging and pumping it. Then inserting a flexible liner inside the existing pipe, inflating the liner, and exposing it to heat or ultraviolet light to dry and harden the liner inside the pipe, detailed a report circulated to Council.
“The liner essentially forms a smooth surface inside the existing pipe, restoring it to near-new condition. This method is a cost effective solution with an expected additional fifty year lifespan to existing pipe plus reduces the expense of pipeline replacement,” said Hershmiller.
Funding sources for this project include the: 2024 Sanitary Sewer replacement, Sewer inspections, Distribution systems, Drainage inspections. The city is pulling funding from various operational sources in order to proceed with this project.
As background Hershmiller noted, “The City is continually evaluating the condition of our assets including our water & sewer infrastructure. These evaluations include the consideration for growth and future demands but also for the replacement of aging and failing infrastructure . . .
“One could argue that water availability and the distribution of safe reliable drinking water is the most critical component to Public Health and the economic well-being to the City.
The City’s vast sewage system is made up of 133,000 meters of varied sized sewer pipe. Underground piping, is out of sight and often overlooked in comparison to other infrastructure such as buildings, streets and sidewalks, he added.
