Water Main Maintenance with Water Line Flushing

Filed under: City |

The City of Duncanville Water Utilities Department is beginning its unidirectional flushing (UDF) pilot 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.

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 and sediment 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 these deposits which helps maintain our City’s infrastructure and assures consistent high quality water.

The flushing schedule will be posted on the City’s Public Works’ Webpage at www.duncanville.com. Flushing will normally occur between the hours of 7am-3pm. In some cases water service may be interrupted, but only for a short time. 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. Complaints about water quality are monitored, please notify us of any concern @ 972-780-4900.

Please note that this process does not affect your water bill, nor does it waste water as the amount and cost of water used in flushing is a small price to pay compared to the benefits of assuring the quality of your water and maintaining our infrastruture.
