The City is replacing the pressure reducing valve (PRV) chamber located in the intersection of Welham Road and Saunders Road. The PRV chamber is an integral component of the City’s water distribution system that regulates water pressures within the system; the valve in a watermain automatically lowers the incoming high-water pressure to a safer, consistent downstream level to protect plumbing systems and reduce water waste.
Project Updates
April 21, 2026
Construction is underway to replace the PRV chamber at the intersection of Saunders Road and Welham Road.
To safely complete this work, the intersection is currently closed to through traffic and will remain closed until the project is finished. Access to adjacent businesses and properties will be maintained, and emergency services will continue to have access at all times. Motorists are asked to follow posted detours and construction signage. Details are posted at barrie.ca/RoadClosures.
The contractor has begun installing new storm water culverts across Saunders Road and Welham Road. New watermains installation is expected to begin in the coming weeks as preparation for the new PRV chamber construction.
As part of this work, there may be short, temporary interruptions to the water supply in the area. Advance notice will be provided to affected residents and businesses prior to any planned water service disruptions.
