About RiverRenew

What is RiverRenew

RiverRenew is the largest infrastructure initiative in the history of Alexandria, addressing a 2017 Virginia law to achieve healthier waterways by July 1, 2025. RiverRenew includes multiple projects that consist of a new tunnel system and upgrades to Alexandria's wastewater treatment facility owned and implemented by Alexandria Renew Enterprises (AlexRenew). 

The RiverRenew tunnel system will connect to four outfalls in Alexandria that date back to the 1800s. These outfalls are part of a legacy combined sewer system that only has one pipe to carry both sewage and rainwater. During rain events, the capacity of the combined sewer system is often exceeded, resulting in overflows from the outfalls that pollute Alexandria's rivers and streams. The tunnel system will capture millions of gallons of combined sewage from these outfalls for transport to AlexRenew, where it will be treated and cleaned prior to returning to the Potomac River.

RiverRenew is a program owned and implemented by Alexandria Renew Enterprises, with support from the City of Alexandria

Led by a five-member citizen board, Alexandria Renew Enterprises (AlexRenew) is a special-purpose authority that has been serving the City of Alexandria and parts of Fairfax County for the last 60 years. AlexRenew treats an average of 35 million gallons of wastewater per day from more than 300,000 people at its water resource recovery facility, located in Alexandria’s southwest quadrant.

In keeping with our water protection mission, AlexRenew will lead the planning and construction of RiverRenew to ensure its implementation by 2025.
