CSO Abatement Project Overview and Progress by Paul Nordstrom

The CSO Abatement Project, presented by Paul Nordstrom, Director of Operations and Engineering, aims to manage combined sewage overflow through a multi-phase approach. Currently in Phase 1, which is under construction and expected to complete by October 2008, the project carries a cost of $320 million. Phase 2 design work is set to begin in August 2007. Key infrastructure includes a pump station, storage site, and wet weather treatment capacity. The facilities will manage an average daily flow of 0.45 MGD with a peak capacity of 0.77 MGD.
