Watermain Replacement & Rehabilitation

OVERVIEW

The purpose of these projects are to replace sections of water line that have been identified as requiring repair and maintenance or reaching their end of life. In 2022, a comprehensive Water Master Plan was completed by WSP Canada, identifying the current condition of the City's water supply network, and identifying upgrades necessary to align with the anticipated growth identified in the Official Community Plan.

Projects identified in the watermain replacement and rehabilitation program for 2026 include:

  • Third St East SIPP Lining (Mackenzie Ave to Vernon Ave)
  • Fifth St East SIPP Lining (McArthur Ave to Vernon Ave)


OVERVIEW

Since 2023, the City has been utilizing Spray in Place Pipe Lining as a form of rehabilitation for ageing water main infrastructure as an alternative solution to full pipe replacement. The lining process fully cleans the pipe, inspects it for condition and then sprays the inside of the pipe with a Resiline 320 liner to provide a full coat.

Prior to being returned to service, the pipe is disinfected and tested according to standard watermain construction procedures.

This approach has numerous benefits, including:

  • Shorter construction duration.
  • Less impact on surrounding residents and businesses.
  • Significantly smaller excavation areas.
  • Improved fire flows (dependent on pipe material).

Previous projects where this technology has been utilized in the City include:

  • Fifth St East (Mackenzie Ave to McArthur Ave)
  • Pratico Rd (west of Airport Way)
  • Pearson Ave (First St to Second St)
  • Mackenzie Ave (Victoria Road to First St)
  • Fourth St East (Granite St to Edward St)
