Spring Hill Sewer Separation Project

The Spring Hill Sewer Separation project is one in a series of efforts to mitigate flooding, reduce waterway pollution, and upgrade infrastructure throughout Somerville. It aims to include:

• Installation of new storm drains to separate stormwater flow from the existing combined sewers
• Upgrades of existing storm drains
• Installation of green stormwater infrastructure
• Improvements to the tree canopy
• Improvements to the streetscape
• The street design will consider the needs of pedestrians, cyclists, transit riders, and motorists through a public process

Currently, the Spring Hill Sewer Separation project is in its design phase. It has been divided into two areas: Project Area 1 and Project Area 2, as illustrated on the right side map (click image to enlarge). Project Area 1 will advance to construction in 2021 while Project Area 2 will advance to construction in 2022 at the earliest.

To date, there have been two community meetings to discuss design elements of the project. The presentations and recordings can be viewed in the menu to the right.
