DC Water Reminds Public of Upcoming Community Meetings on Potomac Interceptor Response, March 18, 19

March 17, 2026
Community Meeting Graphic

While DC Water has completed the emergency repair of the Potomac Interceptor, we are committed to transparent communication with the community who still have questions about the work and ongoing environmental rehabilitation efforts. As part of this open dialogue, we are reminding community members of additional opportunities to engage with DC Water at two community meetings this week: tomorrow, March 18, in Bethesda, MD and Thursday, March 19, in Alexandria, VA.

DC Water completed the emergency repair on the damaged pipe and returned flow to the interceptor on Saturday, March 14. Work is now transitioning to the long-term rehabilitation of more than 2700 linear feet of the pipe in this area. The work is being accelerated and was part of a previously planned rehabilitation project. Progress is also being made on the environmental rehabilitation underway, including the initial clean-up of the C & O Canal which began immediately upon completion of the repair.

The community meetings will focus on more direct engagement with the community, including an open-house format with a shortened presentation to allow more time for Q&A and information tables to engage with subject-matter experts.

DC Water Breaks Ground on Piney Branch Tunnel, Final Phase of DC Clean Rivers Project

Today, DC Water broke ground on the Piney Branch Tunnel, the final major tunnel in our Clean Rivers Project. This work will help keep sewage and trash out of local waterways and make Rock Creek, the Potomac River, and the Chesapeake Bay cleaner for our community.

When we finish the Piney Branch Tunnel, it will hold at least 4.2 million gallons of rainwater and wastewater during heavy storms. Instead of overflowing into Piney Branch, that water will go to the Blue Plains Water Resource Recovery Facility, where it will be treated.
