Water Distribution System
The Town of Vienna's water distribution system consists of 131 miles of pipe serving approximately 14,000 residents inside the Vienna corporate boundary and 4,000 customers outside of the corporate boundary.  On the map, the light blue indicates the water service area inside the corporate limits of the Town and the dark blue indicates the water service area outside the Town limits.

Each spring, the water distribution system is flushed using existing fire hydrants.  While this operation is going on, each fire hydrant is checked for proper operation.

The Water Division crews maintain the water distribution system through completion of daily tasks and responding to emergency maintenance issues when they arise.

Water Main Breaks
During times of extreme weather fluctuation pipes, soil, and water expands and contracts at different rates which occasionally causes water main breaks. When there is a break crews will shut off the water flow and this will  interrupt resident’s services as the repair is completed. Once water is back on, residents may want to run their water for a few minutes to ensure that the water is completely clear. Town residents’ water bill is not affected when a break occurs. If a water main break has happened in your area call the Department of Public Works immediately at (703) 255-6380. After regular business hours, call the Vienna Police non-emergency number at (703) 255-6366.
