Updated at 1:55 p.m. The Arlington County Board on Saturday approved $6.5 million in contracts for a new water main project on Williamsburg Boulevard and a sewer pipe upgrade at the intersection of Lee Highway and John Marshall Drive.
The Williamsburg Boulevard Water Supply Main project is the second phase of the county’s effort to connect the Ethan Allen pump station to the Minor Hill Reservoir. Part of the water main, from the pump station to north Glebe Road, was completed in 2003. The segment from North Glebe Road to 34th Road North is under construction.
The $5.6 million project was awarded to Alexandria-based contractor Martin & Gass Inc., which will lay the 36-inch water main in Williamsburg Boulevard beginning at 35th Street North and ending at the reservoir. The new water main will provide water supply to Minor Hill, which will allow for maintenance on existing water mains without service disruption, according to an Arlington County press release.
The entire water main should be completed by September 2013, according to Shannon Whalen McDaniel, spokeswoman for the Arlington County Department of Environmental Services. The new phase of the project will begin in December.
About $900,000 of the approved funds will go toward sewer improvements at John Marshall Drive and Lee Highway, an area the county deemed as prone to flooding in a 2011 analysis. Flooding during a June 2006 storm damaged area homes, which prompted the stormwater study. The project is scheduled to begin in September, McDaniel said.
“As our County continues to grow and age, it is critical that we make ongoing, prudent investments in our infrastructure,” said County Board Chair Mary Hynes. “The upgrades that the Board approved today will help improve the operations of our essential water and sewage systems, protect against flooding and allow us to continue delivering first-class services to our residents.”
