Washington Street Water Main Upgrades

Beginning on or around July 22, 2019, the City’s contractor, Tim Zanelli Excavating (TZE), will upgrade a water main beneath Washington St. between Line St. and Somerville Ave. 

The water main in this area dates as far back as 1888. Old pipes suffer from tuberculation, a form of corrosion, which reduces the amount of water that the pipe can supply. 

As part of this project, some sections of the water main will be replaced with new, larger pipes, and others will be cleaned and lined with cement to improve water flow. Valves and hydrants will also be replaced to provide better system functionality.

While all timelines are subject to change, work is anticipated to be completed in the summer 2020. Daily work hours are approximately 7 a.m. to 5 p.m. 

Some residents will experience interruptions to their water service when contractors install temporary water mains, then again when properties are reconnected to the new water mains. Sign up for the City’s alert system to receive a phone call, email, and/or text message before planned interruptions to your service.

Updated 9/6/2019

  • City contractors have finished cleaning and lining the water main with cement on Washington St. between Beacon St. and Hawkins St., which will improve water flow.
  • During the week of September 9, crews plan to excavate between Hawkins St. and Webster Ave. to replace that section of the water main, which may require lane shifts.

Updated 8/30/2019

  • Crews are cleaning and lining the water main with cement on Washington St. between Beacon St. and Hawkins St. and digging pits between Hawkins St. and Webster Ave. to replace the water main, requiring parking restrictions and lane shifts.

Updated 7/19/2019

  • Work is expected to begin Monday, July 22, on Washington St. between Line St. and Somerville Ave. Contractors will begin installing temporary piping that will provide water service when the existing main is decommissioned for upgrades.
  • Some residents will experience interruptions to their water service during construction. Sign up for the City’s alert system to ensure you're notified in advance.
  • This project's approach will be similar to the recently completed work on Pearl St.; click here to hear our engineers explain exactly what to expect.

Updated 7/8/2019

  • Work is expected to begin the week of July 22, 2019.

As with all construction, schedules are subject to change due to weather or other unforeseen circumstances, but we anticipate the following sequence of work:

  • Summer - Winter 2019: Replace water main, Beacon St. to Line St.
  • Summer - Winter 2019: Clean and line water main, Beacon St. to Hawkins St.
  • Fall 2019 - Spring 2020: Replace water main, Hawkins St. to Somerville Ave.
  • TZE will patch sections of pavement as they complete work in each area and again after the winter freeze-thaw cycle. This segment of Washington St. is expected to be repaved in its entirety in 2021 as part of the City’s pavement management program.

Traffic

  • Washington St. is expected to remain open to through traffic for the duration of the project. 
  • Lane closures, lane shifts, and parking restrictions may be implemented as needed.

Water Service Interruptions

  • Some residents will experience interruptions to their water service when contractors install temporary water mains, then again when properties are reconnected to the new water mains. 
  • Sign up for the City’s alert system to receive a phone call, email, and/or text message before planned interruptions to your service. Flyers will also be distributed to affected properties in advance. 

Noise

  • Excavation may produce moderate noise during work hours (typically between 7 a.m. and 5 p.m.) along the length of the project. Crews need to excavate to access the existing water main in order to replace and line the pipes.

The City of Somerville offers a number of ways to stay informed about construction.
