    Reduction of CSO frequency and volume for New York City’s Bowery Bay Catchment

    Reduction of CSO frequency and volume for New York City’s Bowery Bay Catchment

    Challenge

    New York Department of Environment and Planning is currently evaluating operational and capital improvement alternatives to reduce the frequency and volume of combined system overflows. Aguazé Solutions evaluated alternatives using Optimizer ICM to reduce CSO volume and activations during the typical year rainfall events.

    Solution

    A multi-objective optimization analysis was performed on the collection system to simultaneously balance capital investment against level of service. For this project, level of service improvements were defined as a reduction in CSO activations/volume while having minimal change to the existing system HGL. Alternatives evaluated include changes to regulator structures, interceptor improvements, and pump station balancing at the WWTP.

    Estimated Cost

    $1-30M

    CSO Activation Reduction

    7-30%

    CSO Volume Reduction

    40-66%
