RiverRenew Tunnel System Project, Alexandria, VA

The RiverRenew also known as the RiverRenew Tunnel System (RRTS) is part of the largest infrastructure project in Alexandria, Virgina’s history. This is a signature project of the Alexandria Renew Enterprise (AlexRenew, the Owner). RPTS will capture millions of gallons of combined sewage from four existing outfalls each year and transport them to AlexRenew for treatment.

The RRTS project includes a waterfront tunnel and four construction staging areas (CSAs), a system of surface facilities, deep shafts, tunnels, diversion sewers, and treatment facility upgrades to divert, convey, store, pump, and treat flows from the combined sewer outfalls
