The Poplar Street Pump Station will fundamentally transform the way stormwater is managed for roughly 60% of the city.

When completed the pump station and associated 4-million-gallon stormwater storage tank will deliver a range of benefits including:

  • Flood reduction across Wards Two and Three

  • Healthier water ways by reducing discharge of sewage (CSOs) to nearby waterways during heavy storms

  • Expanding capacity for development throughout the city

The pump station is one in series of the projects the City is undertaking to better prepare our stormwater systems for the effects of climate change.

About Construction

Construction began in spring 2023 and is expected to continue through 2027. The project team reach a significant milestone with the installation of the stormwater storage tank’s roof in late March 2025.

With the tank nearing completion, crews have turned their attention to construction of the pump station itself. Periodic updates about construction and associated impacts will be posted to the page below.

Future Use of the Site

Following construction of the pump station, the City has proposed using this site as Somerville’s next great public space.
