About this Project:
MWRA’s Northern Intermediate High (NIH) pressure zone has supplied water to the communities of Reading, Stoneham, Wakefield, Wilmington, Winchester, and Woburn through a single 48-inch diameter pipeline, fed by the Gillis and Spot Pond Pumping Stations in Stoneham. MWRA recently completed the NIH Redundancy Project with the installation and activation of the new Section 110 pipeline through the communities of Stoneham, Reading and Woburn. Section 110 provides full pipeline redundancy for the water supply to the NIH communities. Activation of the new Section 110 pipeline has allowed MWRA to proceed with design and construction for the replacement of Section 89, which has previously been the single transmission line to the NIH communities. Section 89 was installed in the 1970’s and is made of material called pre-stressed concrete cylinder pipe (PCCP), which has been susceptible to catastrophic failure. With the new redundant water pipeline in place, MWRA will be able to proceed with the replacement of the vulnerable PCCP portions of Section 89 with the new ductile iron pipe. This $32.6 million contract was awarded to P.Gioioso & Sons, Inc. in May 2021 for a contract term of 1475 calendar days from the Notice to Proceed.
Summary Scope of New Work:
Section 89 of the Northern Intermediate High Pipeline is being replaced for added water distribution and redundancy in the Town of Winchester, Woburn, Stoneham and the Town of Wakefield.
Construction Update (December 4, 2023)

- The MWRA and its contractor, P. Gioioso & Sons of Hyde Park, MA, will be working along Washington Street between Montvale Avenue and Utica Street and along Montvale Avenue between Albany Street and Washington Street at night from 7:00PM to 5:00AM. Work will be conducted Monday through Thursday (into Friday morning) starting on Monday, August 14, 2023.
- This first phase involves replacement of the City water lines and sewers on Washington Street to create a corridor for the new 48-inch MWRA water pipeline.
- Once the City water and sewers are relocated, the second phase will move to Montvale Ave to begin removing the existing MWRA water pipeline and installing a new 48 inch water pipeline under the roadway.
- Work is expected to last approximately two to three months.
- In order to safely conduct the work, this section of Washinton Street will have limited access to through traffic; and two vehicular lanes will be closed to traffic along Montvale Avenue (one lane in each direction will be open).
- Importantly, access to businesses or residences will remain available during overnight construction hours.
- Furthermore, traffic patterns will be clearly marked, and police details will be on site to assist with the flow of traffic.
- During non-work hours, Washington Street and Montvale Avenue will not have any traffic restrictions.
