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. 

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.

Town of Vienna water comes from both the Washington Aqueduct, which is overseen by the U.S. Army Corps of Engineers and Fairfax Water.

The Town's sanitary sewer system consists of approximately 95 miles of pipe that delivers sewage by trunk lines to the sewage treatment plants located in Fairfax County and Washington D.C. 

The Sewer Division crews maintain the sanitary sewer system through completion of daily tasks and inspecting and cleaning every sanitary sewer main within the collection system every four years.
