This project will construct a replacement siphon in a jacked steel casing pipe under the Massachusetts Water Resources Authority’s aqueduct that meets current design standards, including redundancy and improved access for maintenance. It will also provide for a future non-siphon (gravity) configuration if the sewer elevation is lowered on Waveney Road and Pleasant Streets.
This work requires a short-term temporary closure of Lanewood Avenue between Waveney Road and Briarwood Road to allow crews to perform the work safely and efficiently. Traffic will detour onto Waveney Way to connect with Waveney Road and Pleasant Street.
Following completion of the sewer improvements, the contractor will restore the work zone to its original state. Restoration work includes loaming and seeding land disturbed during construction, resetting curbs, and temporary roadway paving. Final paving will take place in the spring of 2019 to allow for natural settlement of the disturbed soil over the winter.
City contractor P. Caliacco has completed mobilization and installed an infiltration basin to receive de-watering discharge. Currently the contractor is working on jacking the 42” steel casing pipe underneath the MWRA aqueduct, which is the most challenging part of the project.
The contractor will further extend the sewer pipes by open cut. Weather permitting, the project will continue until December before shutting down for the winter. Lanewood Avenue will re-open during the winter shut down.
