About RiverRenew

In late June 2018, the Virginia Department of Environmental Quality approved a plan to control the discharge of combined sewage to Alexandria, VA’s waterways via four existing outfalls. Now called “RiverRenew,” the program involves the construction of a deep tunnel system and modifications/upgrades to AlexRenew’s wastewater facility. AlexRenew will lead the planning and construction of RiverRenew to ensure its implementation by 2025.
