The City of Waukee Water Department will flush fire hydrants annually beginning in the spring and runs through fall of each year. The hydrants will get flushed once every 3 years rotating areas to cover a third of the City each year.
The program consists of cleaning water mains through a network of flushing sequences with the water being discharged from the largest port on the fire hydrant. It involves closing valves in a specific sequence to create water movement in one direction with opening specific hydrants at the end of each sequence. The importance of the flushing program is to ensure the greatest quality of water throughout the entire system. This technique allows higher water flow velocities to produce better scouring of pipes. This process will dislodge and remove mineral deposits that have accumulated in the water mains.
Benefits The benefits include maintaining and improving the water quality level in the water mains. The flushing program will also reduce bacteriological growth, restore disinfection residuals, improve color, and turbidity, control corrosion, and will help restore fire flows and pressure in the distribution system.
Discolored Water Discoloration in the water may appear. We urge all water users to check their cold water for discoloration prior to drawing water for cooking and for use in automatic washers and dishwashers. If discoloration is found, the water user is advised to discontinue use until the water is clear. This can be accomplished by letting your cold water run until the water clears up. Discolored water is not harmful to your health.
The flushing will take place during the hours of 7 a.m. to 3:30 p.m. on weekdays. There might be a slight drop in pressure. Otherwise service should not be affected by the flushing program. We urge resident to use caution with traveling around the Water Department Personnel.
