Spring Hill Sewer Separation Project

Share on Facebook Share on Twitter Share on Linkedin Email this link

Largely developed during the 19th century, Spring Hill is served by a combined sewer system that collects both wastewater and stormwater runoff in the same pipes. The City is currently working to upgrade these systems by installing new storm drains that separate stormwater from the existing combined sewer. This measure is one in a series of actions the City is undertaking to reduce water pollution, mitigate flooding, and ultimately modernize our infrastructure.

In addition to the installation of a modern, separate sewer system, the project includes:

The Spring Hill Sewer Separation project has been divided into two areas: Project Area 1 and Project Area 2, as illustrated on the limits of map on the right-hand side of this page (click image to enlarge). Construction has begun in Project Area 1 while Project Area 2 will advance to construction in 2023 at the earliest.

  • Highland Ave. (School St. to Central St.) Westbound Traffic Detour

    Share on Facebook Share on Twitter Share on Linkedin Email this link

    Beginning on or around December 12, City contractors will begin working on subsurface utility improvements along Highland Ave.

    During this phase of the project, Highland Ave. will be closed to westbound traffic between School St. and Central St. during work hours (7 a.m. to 7 p.m. on weekdays). The eastbound travel lane will be maintained as usual.

    All businesses will remain open and accessible during construction.

    Westbound Detour Route

    Westbound traffic will be detoured south on School St. and west on Summer St. before turning right on Lowell St. to return to Highland Ave.



    Pedestrian and Transit Impacts

    Sidewalk access for pedestrians may be restricted at times to facilitate construction of new utilities within the sidewalks. Temporary sidewalks will be installed to maintain safe crossings so as not to impede pedestrian travel, and allow access to businesses and residences along the affected stretch.

    MBTA buses 88 and 90 will be allowed to proceed along Highland in both directions during the detour. However, stops at School St., Trull Ln. and Central St. may be temporarily closed to accommodate the utility work.

    * Please note that this project does not include any streetscape improvements on Highland Ave. A separate, future project will incorporate new streetscape designs and roadway resurfacing.

    If you have questions, please email construction@somervillema.gov or call the Engineering Division at 617-625-6600 ext. 5400.

  • Importance Notice for Residents Connected to Temporary Water Service (11/15)

    Share on Facebook Share on Twitter Share on Linkedin Email this link

    An important notice for residents currently connected to water service via a temporary water line (image included for reference), as part of the Spring Hill Sewer Separation project:

    When outdoor temperatures (including overnight) drop to 32ºF or below, the water in the temporary blue hose may freeze, resulting in an interruption to your water service.

    IMPORTANT: It is critical that starting today, you leave at least one water tap running inside your home overnight while temperatures are below 32ºF to prevent a frozen waterline and ensure you have continuous drinking water.

    Locate the tap (or faucet) on the lowest level inside your home. Allow a pencil-sized trickle of water to come out of the faucet so that water continues to flow through the temporary blue hose to prevent freezing. Keep the trickle of water running all night until the hose is disconnected from your outside tap by the City’s contractor, or until overnight temperatures rise above 32ºF.


    Shutting off the faucet if the temperature is below 32ºF may cause the water in the blue hose to freeze, resulting in an interruption of water service to your residence.

    While you are connected to the temporary water service, your water bill will be estimated. You will not be charged for the additional water used to keep your waterline from freezing.

    Work is scheduled to be completed within the next two weeks. When the work is completed, the blue hose will be removed and the watermain will be back in service.


    Affected residents should receive additional notification via the attached flyer delivered to their residence.

  • CIPP Sewer Restoration - Week of 8/29

    Share on Facebook Share on Twitter Share on Linkedin Email this link

    Weather permitting, City contractors will rehabilitate aging sewers using a method called cured-in-place-pipe lining (CIPP lining) to provide more structurally sound pipes without excavation.

    Locations:

    • Avon St. (Central St. to #45 Avon)
    • Highland Ave (Central St. to #138 Highland)
    • School St. (Oxford St. to Highland Ave.)
    • Oxford St. (#59 to #97)
    • Carter Terrace
    • Central St. (Berkeley St. to Cambria St.)



    Anticipated Work Schedule (subject to change): Work expected to take place during the week of 8/29. Weekdays between 7 a.m. and 7 p.m. Schedule is subject to change due to weather or other factors. Hours may extend to 10 p.m. on certain streets with larger diameter sewers.

    Odor: Plastic- or glue-like odors may be detectable when the liner cures. This will dissipate quickly once the process is complete. If you are sensitive to odors, consider opening windows or doors to increase airflow.

    Noise: Moderate noise expected from truck engines and equipment.

    Traffic Impacts: On-street parking restrictions expected on both sides of the work zone. Isolated street closures will be in effect. Onsite crews will provide detour signage and help abutters get in and out of their driveway as needed.

    If you have questions, please email construction@somervillema.gov or call the Engineering Division at 617-625-6600 ext. 5400.
