We continue our three-part series on Combined Sewer Overflow systems as assembled by VWEA's Collection Systems Committee. In this episode , the series host Kyle Logue (Greeley and Hansen) catches up with Patrick Bradley (City of Richmond at time of recording) to review the history of federal and Virginia CSO regulations that shaped the strategy for infrastructure construction, operation, and management. Note that this episode was recorded in March 2022, and reflects the state of regulations at that time.
