DC Water, National Park Service, Community Groups Celebrate Fresh Air Along Potomac Interceptor

May 30, 2013

It’s been more than a decade in the making but the day has finally arrived. Join DC Water, the National Park Service and various community groups as they cut the ribbon on a series of odor scrubbing facilities that keep the air fresh along the Potomac Interceptor Sewer and C&O Canal. The facilities are enabling DC Water to remove the majority of the vents along the Potomac Interceptor that vent sewer gases to the air. Already, half the vents have been closed.

Visuals include new facilities, a ribbon-cutting and the scenic C&O Canal.

Graphic with the information for the Community Meeting

As DC Water continues repair efforts on the Potomac Interceptor sewer line, we want to provide an opportunity for the community to engage with us on Wednesday, February 25, to ask questions, and learn more about the response, impacts to the Potomac River, and next steps in the emergency repair and long-term rehabilitation efforts.

Trench box being installed to expand excavated area

Repairs are moving forward, with crews closer to reaching a debris dam and large rocks blocking a section of the damaged Potomac Interceptor. Work has been completed to fully extend the excavation site and install trench boxes to stabilize and isolate the additional pipe sections. No overflows entering the Potomac River have occurred in 16 days.

The excavation around a damaged section of the Potomac Interceptor has been extended and trench boxes installed to provide shoring and stability. This doubles the size of the excavated area, to connect the collapse site with a downstream access point to the Potomac Interceptor.
