Through the Metropolitan Water Tunnel Program (MWTP), MWRA will construct two new water supply tunnels that will provide redundancy for MWRA's existing Metropolitan Tunnel System, and allow our aging existing water tunnel system to be rehabilitated without interrupting service.

Schedule
Final design is anticipated to start in 2024 with a target for the first tunnel construction contract bidding in 2027.

Work in Project Host Communities
The MWTP is planned to be constructed in seven communities: Boston, Brookline, Needham, Newton, Waltham, Weston and Wellesley. To support the tunnel design, MWRA is performing geotechnical investigation field work consisting of test borings and various types of surface geophysical testing to better understand the subsurface conditions that are likely to be encountered during construction. Depending on the location, this work may be seen along city streets and can have impacts on neighborhoods. MWRA’s Community Relations Department works with municipal staff and residents to ensure good communications during these projects.
