It enhances water quality by removing sediments from inside the mainline and flushing them out through the hydrant; identifies malfunctions of the hydrant and related valves; helps determine weaknesses in the water distribution system; identifies inadequate water volumes and pressures in the mainlines and helps determine locations where flow pressures may require valve inspections.

  • Mainly, avoid using the dishwasher, washing machine and don’t turn on the faucets (hot or cold). Wait until the operation is completed.

  • If you are driving in the work zone where hydrants are being flushed, please drive carefully.

When a hydrant is opened, the water in the mainline will flow out at a high velocity. This creates a scouring action in the pipe and dislodges fine sediment particles that have accumulated in the pipe. The fine sediment mixes with the water, turning the water a cloudy or rusty brown color. This mixture is discharged out of the hydrant.  Remember, after the hydrant flushing operation, run your hot and cold faucets to let the water clear before you use it.
