The document provides an update on water quality studies being conducted to develop a Long Term Control Plan for combined sewer overflows (CSOs) as required by a consent decree. Flow monitoring and water quality sampling have been completed, and hydraulic and water quality models are being developed and calibrated to assess CSO impacts and evaluate control alternatives. Key accomplishments include characterizing system flows, monitoring water quality during rain events, and developing preliminary hydraulic models of the sewer system. Upcoming steps involve further refining the models and using them to identify long term CSO control options.
