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 Fall water main flushing program will commence on October 3, 2023 in various areas of Colwood and Langford.
Why do we flush our water mains?
Water main flushing is a technique used to clean water distribution pipes and reservoirs of sediments that build 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 (source to extremities). The flushing program is conducted yearly 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.
How does water main flushing affect your water?
During the flushing process, low pressures and discoloured water may be experienced for short periods. 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, turn on your cold water taps (after flushing hours) and allow it to flow until the water runs clear. Individuals with a weakened immune system should reference the following HealthLinkBC information:
How does the CRD notify the public about water main 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 additional information on the flushing program. Below is a map for the Fall 2023 flushing program.
