Utilities Kingston breaks ground on trunk sewer project

June 5, 2013 -

Ensuring the reliability of Kingston's wastewater treatment system

Utilities Kingston has broken ground on a $9 million project to renew the Ravensview Trunk Sewer.

In 2011, a condition assessment identified that the 65-year-old, 3.4 km long sewer is in poor condition due to hydrogen sulfide corrosion. 

"This work will rehabilitate the pipe for the ongoing reliability of the sewer, environmental protection and public health," explains Jim Keech, President and CEO of Utilities Kingston. "It also ensures another 50 years of service life and improved monitoring of this infrastructure."

The low-dig cured-in-place-pipe (CIPP) lining technology being used is less disruptive and less costly than conventional methods, and results in a joint-less, fully-structural replacement pipe located inside the existing pipe. Maintenance holes will also be rehabilitated and the project will allow for improved long-term access to the sewer. The CIPP technology was selected over other methods because of financial, environmental and social benefits.

"This technology was chosen, in part, because it will result in the least amount of disruption to residents in the area," adds Keech.  

Residents and commuters in the immediate area may notice occasional traffic disruptions, temporary sewer service disruptions and disturbance of landscapes (which will be restored after construction). A project web page at www.utilitieskingston.com will keep residents updated on the work.

Utilities Kingston has awarded the project to LiquiForce Services Inc.

The Ravensview Trunk Sewer carries 60,000 cubic metres of sewage each day and services a population of 80,000.  It begins near Hwy 2 and Hwy 15 and runs through CFB Kingston, Cartwright Point, and along the north side of La Salle Blvd., carrying sewage from Kingston Central and East to the Ravensview Wastewater Treatment Plant.
