 Fire Hydrant Flushing Program

The City of Clive has over 1000 fire hydrants. The best way to ensure hydrants are functioning properly is to flush them annually. Clive flushes all hydrants in the fall. Dead ends are flushed again in the spring.  Dead ends are flushed twice a year to circulate new water into areas that have had water sitting in the line for extended periods without circulation.

If you see a crew flushing hydrants in your neighborhood, you may experience a temporary fluctuation in your water pressure. In some instances the flushing operation can cause sediment in the mains to become unsettled, you may notice a discoloration in your water. THE WATER IS SAFE. The sediment can be easily cleared from the water lines in your home by running the water for 2-3 minutes. 

The procedure for flushing hydrants involves opening one of the three ports of the hydrant and allowing the water to flow wide open for one (1) minute. For the hydrant to operate properly, crews check for ease of opening and closing, ensures that water flow stops when the hydrant is shut down, and if any water remaining in the barrel drains down below ground level into surrounding soil. If a hydrant does not perform all of these functions, the hydrant must be repaired. Hard turning or inoperable fire hydrants can be a serious problem for the Fire Department during emergency situations and any leaks within the hydrant can be a source of water loss and a major cause for hydrant freeze up during the winter months.
