PRV Chamber Replacement Program

The Pressure reducing Valve Chamber replacement program is an annual program to replace the existing chambers. PRV chambers helps to reduce pressure spikes in the water distribution system and also increase water supply during fire events.

2019 Program Details

The PRV Chamber Replacement Program is as follows:

  • Livingstone Street E at Marjoy Ave                
  • Brown wood at Lisa Jane Court
  • Coxmill Road at Dock Road
  • Forest Dale Drive at Sheila Way             

Project Updates

December 16, 2019

Construction has ended for the year and 3 of the 4 Pressure Reducing Valves (PRV) have been installed. Next spring the Livingstone St. East & Marjoy Avenue PRV will be installed. Once the last PRV is installed the final layer of asphalt will be placed at all 4 sites as well as topsoil and sod. The anticipated completion date for the project is June 30, 2020.

October 28, 2019

The Brown Wood, Coxmill Road and Forest Dale Drive chambers have been installed and will be commissioned in the next 2 weeks. Once they are commissioned the disturbed areas will be fully restored. The Livingstone Street PRV Chamber may be delayed until next year. This is dependent on the weather and the progress of the commissioning of the other chambers.

September 19, 2019

Replacement of  the PRV Chambers has commenced at the Brown Wood and Cox Mill Road Sites and is estimated to be complete by mid October.


Estimated Start: August 2019

Estimated Completion: November 2019

Affected Services

Water service, Hydro, Telephone, Cable TV, and Gas services should not be affected by the construction, barring any unforeseen circumstances.  Some temporary interruptions in the sanitary service will occur when the pipe liner material is curing.  You will receive notices of the interruptions at least a day before they are scheduled to occur.

Access to Properties

All reasonable efforts will be made to maintain vehicle access to driveways.  However, there may be some temporary interruptions to access during construction while construction vehicles maneuver.  Access will be restored as quickly as possible.

The Contractor will provide prior notice of any imminent access restrictions to the businesses and residents.

Pedestrian access to all homes and businesses will be maintained during construction.

Garbage Collection

On the normal curbside collection day, place all garbage, organics, recyclables and yard waste materials at the front of your property as usual.  The City's waste pickup contractor is anticipated to have access through the construction site.  If the City's waste pickup contractor does not have access, the construction contractor will remove these items and take them to outside of the construction zone, for pickup by the City's waste pickup contractor.

Your garbage cans, organics bin and recycling boxes will be returned to your property later that day.  Please mark your address on all of your containers.

It is very important that you take your refuse and recyclable items to the front of your property by 7:00 a.m., otherwise these items might not be picked up.


The contractor is required to conduct his work in a safe manner, including working in the middle of the roadway with through traffic.  We ask that you take extra caution during the construction period to ensure everyone's safety.

Emergency Services

Access for emergency vehicles will be maintained at all times.

Traffic Impacts

The contractor will use traffic control measures to permit through traffic through the construction site.  Typically this will include using traffic cones to steer drivers around the contractor's vehicles, which will frequently be parked in the centre of the roadway where sanitary maintenance structures (manholes) are.  Occasionally, flag persons will be required to assist with traffic control.
