On July 14, 2022, AlexRenew welcomed and dedicated Hazel, a 380-ton tunnel boring machine that will build toward Alexandria’s healthier waterways future. Hazel will be used to dig a network of deep tunnels and sewers that will connect to Alexandria's four combined sewer outfalls, preventing millions of gallons of combined sewage from polluting our rivers and streams each year.

This time two years ago, Hazel, AlexRenew’s Tunnel Boring Machine (TBM), was working tirelessly 150 feet below ground. At this point Hazel had completed 70% of Alexandria’s Waterfront Tunnel. Accompanying Hazel was a team of dedicated TBM operators who successfully guided her 24/7 as she made her way from AlexRenew’s treatment plant to what is now the Pendleton Promenade and diversion facility.

Alexandria, VA — AlexRenew announces a significant achievement in its ongoing RiverRenew program: the Hooffs Run Interceptor, one of the project’s primary components, has already reduced combined sewer overflows (CSOs) into Hooffs Run by 90 percent.
