New Sewer Lining Program to Extend Life of Infrastructure

Published on: 2020/07/07 - in Releases

RELEASE — Utilities Kingston is introducing a new annual sewer lining program to rehabilitate aging pipes and improve operating efficiency – using a process that avoids digging up pipes and disrupting neighbourhoods.

Starting in July, up to 5,000 metres of sanitary sewer main will be lined in Kingscourt.

“At Utilities Kingston, we focus on providing Kingston with safe and reliable utility services. We are committed to environmentally-sound wastewater collection. You can count on us!” says Jim Keech, President and CEO of Utilities Kingston.

Aside from renewing the infrastructure, this work reduces otherwise clean storm water from infiltrating the sanitary sewer system, increasing pipe capacity and reducing the risk of localized basement flooding. The work will also increase operating efficiency, as reduced sewer flows mean less pumping and treating wastewater.

Instead of digging up the road along the entire length of the sewer main, Utilities Kingston’s contractors, Empipe Solutions Limited and Insituform Technologies Limited, will access the pipe through maintenance holes to complete the work. This involves preparing the inside of the sewer mains and then inserting a felt liner that is saturated with a resin. This resin compound is then cured-in-place to form what is, essentially, a ‘new pipe within a pipe’.

Kingscourt residents

The lining work will typically be completed within a 6 -hour period. Residents in the affected area will be notified approximately 1-2 weeks prior, and again 24-48 hours prior to the lining process.

When the liner is initially inserted, it will temporarily block the sewer laterals that carry wastewater from homes and businesses to the sewer main under the street. Our contractor will cut these out to open the service, but residents will need to take temporary measures to reduce the wastewater coming from the property.  These measures are clearly outlined in the notices to be provided.

It will be important that residents in the work area take steps to avoid filling the sewer lateral with wastewater, creating a risk of sewer backup to the home.


  • Use cottage rules for flushing.
  • Wait to shower, wash clothes or run the dishwasher until they are notified that the work is complete.
  • Delay washing cars.
  • Every little bit helps: for example, you can turn off the water when you shave or brush your teeth.

As we carry out work in your neighbourhood, Utilities Kingston and our contractors remain committed to the health and safety of our workers and the public. We are adhering to all relevant safety guidelines released by Ontario to protect workers, customers and the general public from COVID-19.

We will not enter customer premises (unless in an emergency situation). Please practice physical distancing by keeping at least two metres away from our employees and contractors.
