ALL HYDRANTS ARE REQUIRED TO BE FLUSHED TWICE ANNUALLY
A hydrant testing and flushing program is very important to the maintenance of a domestic water distribution system. Each year, city and/or private water technicians may systematically open hydrants throughout the City to gauge flows and to allow water to flow at a high velocity through the distribution mainlines.
Regular flushing serves the following purposes:
Enhances long term water quality by removing sediments from inside the mainline and flushing them out through the hydrant.
Identifies malfunctions of the hydrant and related valve issues.
Helps determine weaknesses in the water distribution system.
Identifies inadequate water volumes and pressures in the mainlines.
Helps determine fireflows at the hydrant.
You may encounter the following conditions during hydrant flushing operations:
A temporary drop in water pressure to your residence or place of business.
Rusty brown, or cloudy water. (These conditions will subside after the flushing is completed.)
Helpful Hints to Remember:
Before flushing operations begin, notify customers in areas where flushing is to occur
Do NOT wash white or light-colored laundry during the flushing operations
After the flushing operation is completed:
-Open the cold water faucets and let the water flow until it is clear. Turn off the faucets.
-Open the hot water faucets and let the water flow until it is clear. Turn off the faucets.
-When both hot and cold water are clear, the water is ready for use as normal.
-Check the faucet screens for trapped particles.
-Wash a load or two of dark-colored clothes first.
Why is hydrant flushing necessary?
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.
What should I do when hydrants are being flushed in my area?
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.
