Water System Flushing Program

West Valley Water District is currently flushing pipelines throughout our service area. Flushing is necessary to maintain the successful operation of the District and is required by the State Water Resources Control Board – Division of Drinking Water. Flushing involves running water at high speeds through hydrants or blow-off valves to remove sediment that builds up at the bottom of the water main over time

The District continues to engage in water conservation and when water is flushed at this velocity and volume, it seeps back into groundwater supply to minimize water loss. We only release the optimal amount of water to sufficiently flush pipelines. Here are a few reasons why flushing is beneficial:

  • Reduces damage from corrosion and prevents bacteria growth by pushing water through pipelines at high speed
  • Removes sediment and mineral deposits that can affect water taste, color, and odor
  • Ensures that hydrants and valves will work properly to better respond during emergencies
