Project Win! RiverRenew Tunnel System Project

As lead partner of the Traylor – Shea Joint Venture and in partnership with lead designer Jacobs and subcontractor Corman Kokosing, Traylor has been selected to design and build the RiverRenew Tunnel System Project for Alexandria Renew Enterprises in Alexandria, VA.

In response to a 2017 Virginia law to clean up local waterways, AlexRenew is tasked with remediating four combined sewer outfalls by July 1, 2025. The project will involve design and construction of a storage and conveyance tunnel system, pumping stations, and a wet weather treatment plant, located within one mile of our East Coast office in Old Town Alexandria and five miles away from Traylor’s award-winning Blue Plains Tunnel Project. Once complete, RiverRenew will capture 98% of combined sewer flows and reduce the frequency of sewer and rainwater overflows into local rivers and streams from 70 to fewer than four times per year. Notice to proceed is expected in December of 2020.
