North Allston Storm Drain Extension Project (NASDEP) 

NASDEP is a project for the Boston Water and Sewer Commission (BWSC) that is designed in collaboration with Harvard University to alleviate the existing inundated storm water systems in the North Allston neighborhood. The proposed modifications to the BWSC stormwater management system will significantly improve its performance by providing much needed additional conveyance capacity. The enabling work for the project began in 2021 and will continue through 2025. The increased capacity systems are designed to extend from the area south of the new Science and Engineering Complex (SEC), connecting to an existing stormwater drain system in Rena Park, routing through the ERC and following behind the National Resilience Inc. (formerly Sanofi/Genzyme) facility before crossing Soldiers Field Road to an outfall in the Charles River.
