Poplar Street Pump Station Project - Pump House & Facilities The Pump Station will serve as a restoration of a century-old drainage pathway for the greater Union Square area, taking advantage of excess capacity in the GLX drainage system, redirecting stormwater flow from the MWRA system to a stormwater storage tank and 50MGD pump array designed to optimize the flood-reduction and I/I offset benefits of the GLX connection. Project includes final design services for the Poplar Street Pump Station, 4 million-gallon stormwater storage tank, catchbasin grit handling, odor control, connection to the Somerville Avenue Utility and Streetscape Improvements box culvert, and connection to the MBTA GLX drainage system. Project includes OPM services and CM@Risk for preconstruction services including construction feasibility analysis, scope management, proposing cost-effective construction alternatives, and validating applicability of selected design elements. IAM - Engineering The Pump Station relates to the SAUSI project, Spring Hill Sewer Separation project and future system improvements, allowing for diversion of stormwater flows to the proposed facilities. The overall site development at 10 Poplar Street supports the longer term Brickbottom Vision Planning, serving as a community hub and transit-oriented public space. Necessary New Project First
