Emergency bypass pumping kept wastewater moving while crews investigated the blockage and worked to contain overflows. Those efforts helped prevent over 2 billion gallons of wastewater from entering the Potomac River. #DCWater

Emergency repairs to the Potomac Interceptor are complete. Full flow has been restored and the C&O Canal has been fully drained as part of site restoration. Since Jan 19, crews worked around the clock to stabilize the site and protect the Potomac River. #DCWater

At today’s briefing, we reiterated an important fact: the District’s drinking water is safe and not impacted by the collapse. The drinking water system is completely separate, and intakes are upstream of the site. #DCWater

A cement truck is positioned at the 14th St NW worksite with its metal chute extended over an excavation. Workers stand nearby as part of the tunnel stabilization work. Buildings and traffic barriers line the background.
The abandoned tunnel on 14th St NW was identified during our ongoing work in the area. DC Water’s inspection programs help us flag aging or outdated infrastructure so crews can address conditions like this safely and prevent future issues. #DCWater

Crews stand around an open excavation on 14th St NW, where a pipe opening and nearby utility vault connections are exposed. Construction tools and safety cones surround the work area.
We’re also reconnecting nearby utility vaults to an active sewer before completing the fill. This work requires the northbound lanes to remain closed for now, but we’re still aiming to reopen as early as this weekend, weather permitting. #DCWater

A new review shows 243M gallons overflowed from the Potomac Interceptor collapse, mostly early in the incident. Recent sampling meets EPA ranges at most sites. Crews are preparing equipment to reach the damaged pipe and continue repair work. 🔗 www.dcwater.com/about-dc-wat... #DCWater

Inside the Potomac Interceptor sewer tunnel, where large rocks and debris are visible on the tunnel floor beneath wet, stained walls.
New CCTV inspections found a much larger rock blockage in the damaged Potomac Interceptor. Crews are adding a new access pit and 5 more pumps (13 total) to safely divert flow and remove the rocks, estimated to take 4-6 weeks for system to be ready. Details: www.dcwater.com/about-dc-wat... #DCWater

Work continues on Potomac Interceptor repairs near Clara Barton Pkwy. Large rocks remain a challenge for clearing debris inside the pipe. Clogged pumps and snowmelt caused limited overflows early in the week, but none today.
