[ARCHIVED] Water Main Flushing Program

water main flushing in White Rock

The City of White Rock’s annual Water Main Flushing Program takes place from Wednesday, Oct. 20 through to Tuesday, Nov. 30. Water main flushing is a common process to maintain a City's water distribution pipe system, it also increases the quality of the water inside the pipe system.

The Annual Flushing Program is intended to clean water distribution pipes of sediments that build up over time and improve water quality. This is accomplished by flushing fire hydrants to force water at high velocities through the system.

The 2021 Flushing Program will be carried out between 8 a.m. to 5 p.m., Monday to Friday, with the timing subject to change. Signage will be posted when flushing is taking place on your City block. 

During flushing, residents may experience a drop in water pressure or discolouration of their water. Any disruption should be brief and only occur while mains in the area are being flushed. If you experience a drop in water pressure or loss of water for more than three hours, please call the City’s Municipal Operations department at 604-541-2181.

Visit the City's My Water page for more information on the City’s Water Main Flushing Program.

Frequently Asked Questions

Why are residents notified by the City of their flushing program?
Residents are notified during water main flushing because some may experience temporary discolouration of water while the water main is being flushed. Any disruption should be brief.

How will I know when flushing will happen near my property?
All residential properties and businesses in the area being flushed will receive a delivered notice prior to the work.
The City will also place signage on the street while flushing is taking place. If you do not receive a notice, your area will not be flushed at this time.

What can I expect when flushing happens in my area?
Water flushing will take place for a few hours. Please do not open the tap during flushing. If you do open your taps, you may temporarily experience cloudy water. Let the water run until the water is clear.
Do not do laundry while flushing is taking place. Check the water supply to make sure it runs clear prior to doing laundry.

Are there any steps I should take once flushing is complete?
After flushing is complete, remove the aerator (a fine mesh grid) on your tap. Then, turn on a cold water tap, preferably the laundry tap, and let the water run for a few minutes.

  • Do not choose a tap that has a water filter connected to it. The sediment may clog your filter.
  • Do not use a hot water tap because it could draw sediment into your hot water tank. 
  • Once the water runs clear, place the aerator back on the tap.
  • Catch some water in a light-coloured cup or container to see if it is clear. If the water does not clear within five to 10 minutes, wait two hours and try again.
