What is flushing?

Each fall the Department of Public Utilities begins its comprehensive unidirectional flushing (UDF) program throughout the County. The goal of this program is to ensure the maintenance of water quality at its optimal level and to properly maintain the County’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 the County’s water system.

When will flushing be done in my neighborhood?

See the Flushing Schedule for dates flushing will affect your neighborhood. Please note these dates are approximate. Neighborhoods wherein flushing will take place will be notified by the posting of flushing signs (see picture) near major intersections. Posting will begin 2-4 days prior to flushing and will remain in place during flushing events. Flushing will normally occur between the hours of 7:30 a.m. and 3:30 p.m. during which time water service should not be interrupted. If the water appears discolored we recommend waiting 2 hours to allow the water to clarify. After waiting, run the cold water faucets for 2 minutes to ensure water clarity. If the water does not clear, please notify the Department of Public Utilities at 804-365-6024.

The County has been conducting the annual fall flushing program for the past 7 years. The annual cleaning allows for the continued successful water production throughout the County. The Public Utilities department monitors the process closely and any questions, concerns or complaints are resolved swiftly and respectfully.

Further updates will be made to the flushing schedule on a bi-weekly basis.

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 pipes and can contribute to corrosion and water color problems.

Periodic flushing of water pipes removes the mineral deposits which in turn helps maintain our County's infrastructure and assures consistent water quality.

Is flushing a waste of water?

No! The amount and cost of water used in flushing is a necessity to maintain our infrastructure and to ensure the continued provision of clean water to our County's citizens.

How will you be affected?

Flushing is generally conducted between 7:30 a.m. and 3:30 p.m., Monday through Friday. Select hydrants in each neighborhood will be opened for water pipe flushing. While the hydrants are open, the homes on that block may experience discolored water or a small drop in water pressure. In the unlikely event your water service is interrupted or you are experiencing no water pressure please notify Public Utilities as soon as possible at 804-365-6024.

What if my water appears discolored?

Should your water appear reddish, yellow or brown, do not be alarmed. It is recommended you do not use the water or do laundry for two hours. After you have waited, run your faucets for a few minutes to make sure the water is clear; at which time you may resume normal water use. If the water does not clear after two hours, please notify the Department of Public Utilities at 804-365-6024.
