Annual Unidirectional Water Main Flushing

Service Announcement

The City of Penticton Public Works Department will commence its annual Unidirectional Water Main Flushing Program within City limits beginning May 3, 2021.  Anticipated duration of the project is one month, ending May 31, 2021.

Adopting a unidirectional water main flushing program results in significant water distribution system improvements and cost savings such as:

  • Increased water velocity, which promotes better pipeline scouring and less build up tuberculation.
  • Improved mineral and biological deposit removal
  • Taste and odour control
  • Reduction of turbidity
  • Reduced frequency of waterline flushing
  • Reduced water usage
  • Opportunity for infrastructure preventative maintenance (valve and hydrant exercising)
  • Cost saving over traditional flushing methods from reduced water waste

As a result of the Unidirectional Flushing, water supply to City properties may show signs of sediment and discoloration in various areas.  The sediment is bacterially harmless, however, may cause some discoloration of laundry if not detected.  To avoid any inconvenience, check water supply colour prior to using washing machine by running a household tap for several seconds.

If your property is experiencing dirty water, simply run the cold water tap until water runs clear.  This can take several minutes depending on severity of discoloured water.

We thank you for your cooperation and apologize for any inconvenience you may experience.
