The oldest parts of Alexandria are served by a sewer system that dates back to the 1800s. In this sewer system, called a combined sewer system, only one kind of pipe is designated for transporting both sewage and rainwater. When it’s not raining, these pipes transport sewage for treatment at AlexRenew’s Water Resource Recovery Facility.

On rainy days, the capacity of the combined sewer pipes is often exceeded. Instead of being transported and treated at the Water Resource Recovery Facility, sewage mixed with rainwater overflows into our waterways via four discharge points, or “outfalls.” In April 2017, the Virginia General Assembly passed a law requiring the remediation of these outfalls by July 1, 2025.

AlexRenew is leading a major infrastructure program in response to the 2017 Virginia law to achieve cleaner, healthier waterways in Alexandria. The AlexRenew program is called RiverRenew and features a new tunnel system that will connect to the four combined sewer outfalls, which currently pollute our waterways on rainy days. The tunnel system will capture millions of gallons of sewage mixed with rainwater for treatment at AlexRenew and the cleaned water will be returned to the Potomac River.

AlexRenew’s Board of Directors and employees look forward to our continued collaboration with City partners as we implement this historic and environmentally significant program.
