Hydrant Flushing

Hydrant flushing is very important to the maintenance of the City’s domestic water distribution system. Each year the Water Works and Lighting Commission water crew will open the hydrants throughout the city to allow water to flow at high velocity through the distribution mainlines.

Hydrant flushing is done for the following reasons:

  • Enhances water quality by removing sediments from inside the mainline and flushing them out through the hydrant.
  • Identifies any malfunctions of the hydrant and related valves.
  • Helps determine weaknesses in the water distribution system.
  • Identifies inadequate water volumes and pressures in the main lines.
  • Helps determine fire flows at the hydrant.

You may notice the following conditions during hydrant flushing:

  • A temporary drop in the water pressure to your home or business.
  • Rusty brown or cloudy water. Discolored water is not harmful. These conditions will subside in a few hours after the flushing is completed. You can turn on your cold/hot water faucet until the water runs clear.
