Flushing the Fire Hydrant

GRAND JUNCTION, Colo. (KKCO) – The City of Grand Junction is having its annual hydrant flushing program that will begin the week of May 6. This program will be scheduled between 7:30 a.m. and 4 p.m. and will last for two weeks.

On the morning of May 6, the system is scheduled to be flushed on Orchard Mesa with crews ending at 29 Road and Orchard Avenue.

The City initiated a comprehensive flushing program after the 1993 biofilm problems due to the lack of a flushing program. No trace of the biofilm has been found since then and the flushing program keeps water in the distribution fresh and eliminates conditions which allow bacterial growth.

Water Services Supervisor Ron Key says the total amount of water used in the program is approximately 3 million gallons. This is the same amount of water residents use in one day during winter months.

The reasons the water distribution systems are being flushed are:

- Increase chlorine residuals
- Eliminate tastes and odors
- Remove discolored water
- Remove accumulated sediment
- Maintain the life of the mains
- Remove impurities associated with new and repaired mains
- Inspect each fire hydrant and perform routine maintenance

Some effects of flushing may be discolored water, low water pressure and large amounts of water in streets and gutters. These conditions should only be for a short period of time. If discolored water is noticed the water should be permitted to run for several minutes to clear the service line.

If you have any questions regarding the flushing program, please call Ron Key at 244-1572.
