Annual Juan de Fuca Water Main Flushing Program

The Capital Regional District's Integrated Water Services Water Main Flushing Program services communities within the Westshore.

The flushing program will resume October 1, 2024 and include the following communities: Sooke,  East Sooke, Langford, Colwood and Metchosin. 

Why We Flush 

Water main flushing is a technique used to clean water distribution pipes and reservoirs of sediments that builds up over time. This is accomplished by strategic manipulation of fire hydrants and valves to force water at high velocities through the system from previously flushed sections of pipe.

The flushing program is conducted annually and also provides the following system benefits:

  • Improved water quality
  • Improved system hydraulic capacity
  • Improved system operation by identifying weak or problem areas
  • Improved/restored chlorine residual
  • Increased life of system components such as pressure reducing valves, line valves, pumps, etc.

What to Expect During Flushing 

During the flushing process, low pressure and discoloured water are common.  Any discolouration is temporary and is not a health hazard. CRD staff collect and test water samples daily throughout the entire distribution system to ensure that the water is safe for consumption. If you notice any discolouration in your water, run your cold water taps until water runs clear, this should only be done after crews have finished flushing in your area. Please take caution and ensure that water is clear before drinking, showering, doing laundry or dishes.

How We Notify the Public About Flushing

The CRD advertises the Juan de Fuca water main flushing program in local newspapers approximately two weeks prior to the first day of flushing. The CRD also updates its website and social media with exact areas of flushing and additional information on the flushing program.
