FY22 Sewer Improvements During the CCTV Inspection under Sewer System Evaluation Study (SSES) Project, critical defects to the system have been identified. These defects necessitate rehabilitations to ensure continuing system function and integrity of the overlaying roadways. Rehabilitations to the existing system will alleviate the need for costly emergency work when failures inevitably occur in the system. The FY22 Sewer Improvements will be a design and construction project. The rehabilitations proposed will be trenchless repairs to the sewer system. These rehabilitations will be designed based on information gathered in the ongoing CCTV Inspection under Sewer System Evaluation Study (SSES) Project. IAM - Engineering The FY22 Sewer Improvements relate to the ongoing CCTV Inspection under Sewer System Evaluation Study (SSES) Project. This work aligns with the long term goal to evaluate and rehabilitate the entire existing sewer system, city-wide. Sewer rehabilitations further support our department’s goal of reducing Infiltration and Inflow (I/I) to our sewer system as I/I results in additional operational costs as water handling fees paid to MWRA.

Due to the abundance of critical defects in the system, the cost estimate contained herein is not intended to fix all sewer system defects in the study area, rather addressing the most critical defects encountered.
