Raw sewage in C&O

Raw sewage is being diverted into the Canal .... then pumped out back into the 72" sewage line that broke upstream... Can't imagine the clean up is going to be easy Estimated volume... Not necessarily in the canal but ballpark is 40 million gallons..This was 1/23/25

Where is this along the C&O?

I'm not 100% sure... thought they said something about lock 10...
please don't quote me on this.. But from the video's available, they have lined the canal with heavy gauge plastic.. then down river they cut a path through the canal berm to access the 72" pipe and dump into
that.. kinda cool really.. But what a mess .. several million gallons of untreated sewage were dumped into the poor old Potomac.. She has had so much filth and debris dumped over the centuries.. think the powers to be are handling this as well as can be expected considering the conditions and frozen ground.. believe the 72" pipe was installed in 1960.. always think back to when the C&O was officially closed.
1924...What were the river and canal water conditions back then . Some of the tree's in and around the canal are over a century old.. survived Agnus 72, 1996 Wow... so many other floods..
Stay warm

If it were indeed at Lock 10, that would be just inside the Beltway. I would assume that there are no public water system intakes downriver toward DC and appropriate measures are being taken. If there were any good news surrounding this situation, it would be that it’s winter. Raw sewage in the canal in August would be unpleasant if not even more unhealthy. Hopefully the situation is corrected.expeditiously.

I believe there have been reports on the facebook page:Great Allegheny Passage / C&O Canal Enthusiasts. This was posted by Greg Humes, today, 1-30-2026:

"C&O MM 10 Sewage Overflow update (as of late 1/29). I am going to copy/paste DC Water update as some posts with links aren't getting approved. "Today, officials with the U.S. Environmental Protection Agency (EPA), Maryland Department of Environment (MDE), and DC Department of Energy and Environment (DOEE) toured the collapse site. The visit provided a firsthand look into ongoing bypass operations, excavation, and the repair process, underscoring the strong oversight and collaboration among federal, state, and local agencies.

"Crews have excavated a section of the sewer line about 30 feet downstream of the collapse site and removed the crown of the pipe. Active flow is visible indicating the sewer line is partially functioning – despite the damage - with some wastewater getting past the break and continuing downstream in the Potomac Interceptor.

"Work will begin tomorrow to clean debris and obstructions in the pipe, a critical step toward restoring full flow through the system and eliminate dry and wet weather overflows. Additional work will also get underway to stabilize the ground at the collapse site. Trench boxes, acting as giant retaining walls, will be installed around the damaged section for containment and to prevent more erosion. Once debris is cleared and wastewater levels around the collapse drop further, teams will excavate the damaged pipe section to thoroughly assess the damage. This will determine the repairs needed and timeline.

"Eight bypass pumps remain in operation, with crews monitoring the site 24/7 to keep the pumps running through difficult conditions posed by the extreme cold. The system began operation on Saturday, diverting a significant volume of wastewater around the damaged pipe and carrying it back into the Potomac Interceptor further downstream of the collapse."

I hope that helps.

Thanks for that update.

Sincerely appreciate the time and thorough explanation... well done

Here is a link to an article by NPR regarding the sewage leak dated today, 2-7-26 at 7:10 PM:

I think there has been a more recent story on NPR about the sewage issue. There's also an article in USA. I've seen something on facebook about Governor Wes Moore and Trump blaming each other. And tonight Stephen Colbert discussed the issue during his monologue. It's too late for me to get the energy to post all the links to the articles. You can easily find them. For example if you google "USA Today Potomac sewage spill" it will actually bring up 4 articles and several videos.

Awwww thanks Cathy.. Its such a shame. people pointing fingers and zero action...Like most government actions.. its all about visual public interpretations.. Money Money money.. The real issues are going to show up this spring and summer when the temps start to rise.. Bacteria , algae blooms , fish kills, further down the Bay. Remember the fish kills on the eastern shore ....Multiply that ...Millions of gallons..Untreated..in the Canal....Wildlife, people, aquatic species,,People have miss treated these water ways for centuries..one step forward 5 steps back.. Sorry for the ramble. Off topic a bit, Just truly strikes a nerve...Hope you got a bit of rest..
Thanks again
