Starting Monday, a water main replacement project will clog traffic on Colesville Road between Downtown Silver Spring and the Beltway.

According to WSSC’s Frequently Asked Questions document regarding the project, they “will be replacing and relocating approximately 1.88 miles of water mains along US 29/Colesville Road and water connections to intersecting streets. The new water mains will be zinc-coated, ductile iron pipe wrapped in a protective coating. These new pipes have a life expectancy of approximately 100 years.” 

The water mains being replaced are exceeding their life expectancy, having been originally installed in the 1920s. Nearly 40 percent of WSSC’s existing water and sewer mains are more than 50 years old.
