Unidirectional Flushing Program
What is Flushing?
The Public Works Department is beginning its comprehensive unidirectional flushing (UDF) program. The goal of this program is to ensure water quality is maintained at its optimal level and to properly maintain the City's water distribution lines. Flushing is a process by which water is moved through a water pipe at a high velocity so that a scouring action is created. Water is then discharged through a hydrant which in turn removes any material build-up from the pipe. The material removed from this process is harmless and requires no special treatment. Use of this flushing technique is critical to the maintenance of water quality and your water system.
Will flushing be done in my neighborhood?
Locations of flushing will occur in three sections of the City. Click here for map. The flushing operation will start in April and last through May. Flushing will normally occur between the hours of 8 am - 4 pm. Water service should not be interrupted. If the water appears discolored we recommend that you give it a few hours to clear up then run your cold water faucet for a few minutes to make sure that the water is cleared. This type of program has been widely used by other utilities and has resulted in very few complaints. Complaints about water quality are monitored, so please notify us of any concern. Please note the UDF program is different than the routine flushing that the department does. Routine flushing of water lines will continue throughout the year.
Why are we flushing?
Because water mains are sized to allow adequate and safe flows for fire protection, water typically is moving through the underground pipes at less than 2 miles per hour. This slow movement allows mineral deposits, to build up and accumulate in pipes over time. The buildup can restrict water flow in the pipes and contributes to corrosion and water color problems. Periodic flushing of water pipes removes the mineral deposits which helps maintain our City's infrastructure and assures consistent high quality water.
Is flushing a waste of water?
No! The amount and cost of water used in flushing is a small price to pay compared to benefits of assuring the quality of your water and maintaining our infrastructure.
How will I be affected?
You will probably not even be aware that flushing is taking place in your neighborhood. Flushing is generally conducted between 8 am - 4 pm, Monday through Friday. Select hydrants will be opened for water pipe flushing. While the hydrants are open, the customers on that block may experience discolored water or a small drop in water pressure however; your water service should not be interrupted. If you have no water pressure, please notify Public Works at 817-427-6440 as soon as possible.
What do I do if I am experiencing discolored water?
Should a reddish, yellow or brown tint to the water appear, do not be alarmed. It is recommended you do not use the water or do laundry for about two hours. After you have waited, run your faucets for a few minutes to make sure the water is clear at which time you resume normal water use. If the water does not clear within a few hours, please notify the Public Works at 817-427-6440.
