Updated Combined Sewer Overflow (CSO) Control Plan

Project Image

In accordance with the Variances for Combined Sewer Overflow (CSO) Discharges to the Charles River Basin and to the Alewife Brook/Upper Mystic River Basin, the City of Cambridge (City) is developing an update to the Massachusetts Water Resources Authority’s (MWRA) CSO Long-Term Control Plan (LTCP) for the CSO outfalls that the City owns and operates. Through its NPDES CSO Permit, the City is authorized to discharge flows from eleven (11) CSOs. Since the permit was issued in 2009, two (2) of the CSOs have been permanently closed, while two (2) more are temporarily closed pending hydraulic evaluations along the Charles River. Today, four (4) and three (3) active CSO outfalls remain open along the Alewife Brook and Charles River, respectively.

Cambridge is working with and coordinating with the activities of the MWRA and the City of Somerville as they are also developing Updated CSO Control Plans for the variance waters where they own CSOs. For formation on the City of Somerville and the MWRA’s CSO Control Plan efforts visit:
