This project will provide a comprehensive evaluation of experiences, best practices, and costs for  combined sewer overflow (CSO) and wet weather management. The objectives of the study are to (1) evaluate the state of knowledge and research needs for a holistic approach to wet weather management and post-long-term control plans (LTCPs) for CSOs; (2) develop a robust database of practices, costs, and benefits of existing wet weather management strategies; (3) identify gaps in existing knowledge of CSO and wet weather management technology costs and benefits that will support future research needs; and (4) develop a practical guide focused on approaches to enhance post-LTCP wet weather management.
