About this Project:

MWRA Southern Extra High Pipeline Project #7504

Section 111, Dedham

This project will provide water service redundancy for Boston, Canton, Norwood, Stoughton, and Dedham‐Westwood, through construction of a redundant pipeline. The project will also increase distribution storage within the service area to improve system operation and reliability. Work will include the construction of a pipeline from the Bellevue storage tank to East Street in Westwood.

Contract 2 of the Southern Extra High pipeline project has started. The contractor, P. Gioioso and Sons, has completed their first phases of work which involved the protection and wrapping of trees along the pipeline alignment.  Other trees have been marked and removed along Dedham Blvd and further along the alignment. The first phase of pipe work involves the installation of a new drainage line along with the primary focus of installing the new 36” water line.  This work began in the area of Emmett Avenue to just beyond Charity Lane.  Once the drain line has been installed the contractor will go back and begin to install the new 36” water line within Dedham Blvd. from the Boston line and head in the direction of Emmett Avenue.  This work will be continuous with traffic detours in place on a daily basis. 

Additional information, Updates and maps of the road closures and detour areas can be found on the MWRA Website.
