The NASDEP Project involves the construction of a new Boston Water and Sewer Commission (BWSC) drain line between Harvard’s Science and Engineering Complex (SEC) at 140-156 Western Avenue to a new stormwater outfall to the Charles River in Allston, Massachusetts. Phase 1 of the project consists of installation of the drain line immediately south of the planned Science Drive roadway, a portion of Rotterdam Street, and approximately 30 feet to the east of Rotterdam street (herein referred to as the “Work Area”). Dewatering is anticipated to be required for construction of portions of the drain line located below the groundwater table. Additional dewatering effluent may also be generated from surface runoff due to precipitation, and construction-generated water (e.g., wheel washes, decontamination activities).
