Frequently Asked Questions About RiverRenew

Why is AlexRenew leading this project?

To minimize community impact, AlexRenew’s facility will serve as the main construction site for the proposed tunnel system.

Why are we undertaking this project?

Alexandria must meet regulatory requirements to improve water quality in Hooffs Run, Hunting Creek, and the Potomac River.  Portions of the City of Alexandria use a combined sewer system that allows untreated sewage to mix with rainwater during rain events. Once the system reaches capacity, the untreated mixture overflows and pollutes our waterways. A Virginia law passed in April 2017 requires that controls be constructed to capture overflows from the combined sewer outfalls by July 1, 2025.

How much will it cost?

Construction related to RiverRenew is estimated to cost between $350 and $550 million.

How will it be funded?

Revenue for RiverRenew will come from increases in sewer-related fees over the next decade. Efforts are underway to identify other funding sources, including grants through the Commonwealth of Virginia.

When will construction begin?

Construction for RiverRenew is anticipated to begin in late 2020.

When will construction be complete?

Under the 2017 Virginia law, construction to control combined sewer discharges must be completed by July 1, 2025.

What neighborhoods will be affected?

Planning is still underway to determine the exact locations of construction, but a majority of the work is conceptualized to take place at the AlexRenew Water Resource Recovery Facility. Additionally, construction disturbances are anticipated at or near the existing combined sewer outfall locations at Oronoco Bay, Hunting Creek, and Hooffs Run.
