BETA completed design and construction services for over 12,000 feet of 78-inch diameter interceptor through the City of Hartford for the Metropolitan District. This project was considered a major milestone for the District’s CSO abatement program to relieve overflow discharges to the Connecticut River. While this pipeline doubles the overall capacity of the existing Connecticut River Interceptor, which serves as the primary conduit of flow to the Hartford Water Pollution Control Plant, the system’s primary goal is to provide a significant amount of “in-line” CSO storage. The added capacity maximizes the total volume of combined sewage which can be treated at the HWPCP, thereby reducing the volume of CSO discharges to the Connecticut River. To expedite the overall construction sequencing, this $17 million project was divided into two phases. Phase I (9,000 linear feet) is currently complete and operating. Phase II (3,000 linear feet) design is complete, however, not constructed due to insufficient funding.
