Abstract:
RiverRenew is a major infrastructure program to address combined sewer overflows (CSOs) to Alexandria, VA’ s waterways. RiverRenew is one of the most expeditious CSO programs in the United States – resulting from political pressures and a new law requiring the abatement of CSOs by July 2025. This paper will focus on the technical solution – a storage/conveyance tunnel system designed to comply with strict regulatory requirements, the Program’ s design-build procurement approach to meet the aggressive schedule, and the selection of the right alternative to meet the needs of the community and Alexandria, VA’ s unique political landscape.
