PROJECT WORK NARRATIVE
Mystic to Woburn Line Project
MWRA Sewer Lining at Wedgemere Commuter Rail Station
Project Section and Location: Wedgemere MBTA Commuter Rail Station Parking Lot, Ginn Field and surrounding DCR parcel. Bacon Street, Winchester, MA
Why is the work necessary?
The permitted project route through Winchester crosses under the MBTA tracks at Wedgemere Station. The MBTA’s approved construction means and methods for traversing active railroad tracks requires crews to “jack and bore” under the tracks and under three MWRA sewer lines. The MWRA has issued a permit that allows Eversource to conduct this activity near their sewer lines with a condition that Eversource fortify each pipe by lining them using a process known as curing in place (CIP - which consists of installing a specially fabricated resin liner and then curing it in place with steam). This process has been used for more than 45 years to protect a wide variety of structures and pipelines from corrosion, restore structural integrity, reduce infiltration, eliminate leaking joints, improve water quality and increase pipeline flow capacity. Eversource has contracted with Insituform, an approved Eversource and MWRA contractor to perform this work.
Construction Narrative:
Insituform crews working for Eversource will access nine MWRA manholes (three for each sewer line) located around the Wedgemere station platform and adjacent to Ginn Field to clean the pipes and prepare them for the CIP process. Once the pipes are cleaned in August, crews will return in September to execute the CIP process. To complete this process, crews will set up a temporary work zone on the east side of Wedgemere station platform. Pedestrians, commuters and residents can expect to see trucks and equipment set up at manhole locations on the east side of the train platform, one manhole on the west side of the train platform and one manhole on the north side of Bacon Street adjacent to Ginn Field for roughly two weeks.
What to Expect:
• Reliable Service: Be assured that this work will not interrupt electric, sewer or water service to Winchester residents.
• Parking Impacts: o Crews will need to take spots #107 through #110 in the Wedgemere parking lot to access a manhole for three days in late August and three more days in September. o Also in September, crews will also need to take about five commuter spots on the south side of Bacon Street and two commuter spots on the north side of Bacon Street. o Exact dates are not available due to this work being planned around the weather. o No Parking signs will be posted in advance.
• Pedestrian/Bike Detours: Commuters approaching the Wedgemere Station from Ginn Field and the eastern end of Bacon Street near Mystic Valley Parkway will be detoured down the sidewalk on Bacon Street and will access the Wedgemere train platform and
tunnel from the west side (parking lot side). The Tri-Community Bike Path will also be detoured at this section. • Temporary Work Zone: A temporary work zone with fencing and signage to keep pedestrians safe.
• Work Hours and Extended Work Hours: o The prep and cleaning crews will typically work 7:00 a.m. – 3:00 p.m., Monday through Friday o The CIP process cannot stop once it begins and generally last from 16 – 36 hours depending on the size of the pipe. o Crews will be working on three separate pipes of varying size and anticipate working from about 7:00 a.m – 11:00 p.m, on two of the pipes but will be required to work overnight (7:00 a.m. – 7:00 p.m. the following night) on the larger pipe. o A small crew will be onsite to monitor the work at all times. o When working beyond normal work hours, crews will take steps to minimize noise and lighting.
• Community Outreach: o A flyer explaining the work will be posted on the Town’s website, at the work site and distributed to abutting property owners. o The flyer will contain the Eversource Project hotline (1-800-793-2202) and email address (ProjectInfo@Eversource.com) for residents with any questions or concerns.
