Public Notice: North Reservoir Water Main Flushing from April 1 to May 1, 2024



City crews will conduct water main flushing between Monday, April 1 to Wednesday, May 1, 2024.

Water main flushing is a regulatory maintenance practice used to clean water distribution pipes. This is accomplished by sending a rapid flow of water through the water mains. Here’s a closer look into why it is done and what happens:

  1. Remove Sediments: Over time, sediments build up in water mains. Flushing helps remove these deposits, ensuring cleaner water.
  2. Improve Water Quality: The water entering distribution mains is of high quality, but it can deteriorate if not managed properly. Flushing maintains water quality by removing impurities.
  3. Enhance System Operation: Flushing identifies weak or problem areas, improves hydraulic capacity, and extends the life of system components.
  4. Temporary Discoloration: You may experience low pressure and discoloured water during the flushing. Discoloured water is not a health hazard. If discolouration is noticed, run cold water until the water runs clear.
  5. Discharging Water: This is supervised by city staff who ensure the water runoff runs unimpeded to city drains.

If flushing occurs in your area you may experience discoloured water. If this occurs, run your taps in your home or business until the water becomes clear. If you have any questions, please call the City of Langley Operations at 604.514.2910.
