Water Main Breaks Frequently Asked Questions

Water that has been sitting in lines can have air or sediment in it. We recommend running cold water from a tap on the highest floor of your home for five to 10 minutes. If the tap continues to sputter or the water remains cloudy, call our Emergency Dispatch Office at (703) 335-7990. 

Soil characteristics, age and condition of a pipe, and changes in water and ground temperatures can all contribute to water main breaks. Typically, these occur during the winter months. Occasionally, pipes can break if they are accidentally struck by heavy equipment.

Every water main break is different, and the amount of time required to fix them varies due to pipe material, pipe size, the type and cause of the break and how accessible the pipe is. 

Prince William Water crews work to fix a main break safely and as quickly as possible.

We respond quickly to repair the broken water main.  We notify customers if their service will be interrupted during repairs. Water main breaks beneath roadways require a temporary asphalt patch. A contractor will complete permanent paving, typically within 6 to 8 weeks.
