Riverside Drive, Dedham,
Water Main Replacement Project

Project Overview

The Dedham-Westwood Water District’s contractor, Gravity Construction Inc., started water main construction on Riverside Drive the week of July 20.

The work limits for the project include Riverside Drive between Vine Rock Street and Bridge Street, and a portion of Bridge Street between VFW Parkway/Rt.1 and Needham Street. Work will consist of:

  • Removing and replacing approximately 4,200 linear feet of 6-inch cast-iron water main with new 8-inch ductile iron pipe 
  • Installing the District-owned portion of each property’s water service line (properties located within the above project limits)
  • Installing fire hydrants, valves, and associated appurtenances 


The project will be conducted in two phases. The first phase will be on Riverside Drive between Bridge Street and the far end of East Riverside Drive, and the second phase will be between the far end of East Riverside Drive and Vine Rock Street.

While water main construction occurs, a temporary above-ground water main will supply customers with water.

Anticipated Impacts

While construction is underway, access to through traffic will be limited. However, residents, emergency vehicles, and school buses will always be allowed to pass through. The road will be open to normal traffic conditions once construction has finished for the day.

At times, residents will have their water service temporarily disrupted. The District will notify affected residents 24 hours before any planned water disruptions. Sudden water disruptions are unplanned emergencies, and unfortunately, the District cannot notify customers in advance.

Residents are strongly encouraged to sign up for project email updates. The District will send routine communications weekly and, when feasible, emergency notifications.
