Washington Post: Sewage spill in Potomac happened after yearslong construction delays – WTOP News
The Washington Post discovered that D.C. Water had planned to reinforce the ruptured Potomac Interceptor line years earlier, but construction was repeatedly delayed during a federal environmental review.
New information has emerged on the massive sewage spill in the Potomac River in January, when a sewer line in the C&O Canal National Historical Park in Montgomery County collapsed, sending more than 200 million gallons of untreated wastewater into the river.
In an exclusive report, The Washington Post has learned that D.C. Water had planned to reinforce that line years earlier, but construction was repeatedly delayed during a federal environmental review.
Now, D.C. Water and the National Park Service are blaming each other.
Washington Post investigative reporter Aaron Davis broke the story, and he joined WTOP’s Nick Iannelli to breakdown the latest.
Read and listen to the interview below.
The Washington Post’s Aaron Davis speaks with WTOP’s Nick Iannelli about new information on the Potomac Interceptor pipe disaster.
The following transcript has been lightly edited for clarity.
- Nick Iannelli:
There were some concerns about this particular section of pipe have been in the air for a while. What did D.C. Water already know about this section of pipe?
- Aaron Davis:
When this first happened, back in January, we were all asking, ‘When did D.C. Water know about this spot? What did the inspections of this spot show?’
D.C. Water said, ‘Well, we’ve done inspections, and we weren’t expecting anything to be a problem anytime soon in this particular section.’
But the story goes back and starts around 2018, more than seven years ago, when D.C. Water had done a video inspection inside this pipe. Just a little bit upstream of the spot that ruptured, they saw something very concerning. They saw that the metal reinforcements through this concrete pipe were basically dangling, falling out of the top of the pipe, and they said, ‘We need to fix this.’
So they asked the National Park Service in 2018 to fix about a three-quarter-mile stretch to reinforce the whole thing, but almost from the beginning, that whole endeavor falls off the rails. By the following year, in 2019, the project is listed as 255 days behind schedule. D.C. Water says it’s because the National Park Service is doing an extended review.
One of the big roadblocks that happened in the whole scheme of that seven-year time period is in 2021, when it looks like D.C. Water got their approval. But they come back to the Park Service and say, ‘We’re going to have to cut down some more trees. We’re going to have to do a little bit more work to get down there in the pipe.’
And Park Service says, ‘Whoa, hang on. We need to take a more intensive look at this, do a bigger environmental review.’
And that really sets it on a course that is very laborious, and these delays keep compounding to the point where Jan. 19, when this pipe ruptured, they had still not approved the environmental review to conduct the repairs on the section that collapsed.
- Nick Iannelli:
What were some of the things under review during that environmental assessment?
- Aaron Davis:
They go through and they look at something called the ‘buttercup scorpionweed,’ which I’d never heard about, but that’s a blue flower, kind of a wildflower that blooms in this part of the C&O Canal. And they had to mitigate for that.
They said, ‘If we take down too many trees, and they were talking about 260 trees, that would impact something called the northern long-eared bat.’
And so, they had to come up with a mitigation plan for that.
- Nick Iannelli:
So D.C. Water literally said, in these documents that you’ve uncovered, that if this is left unaddressed, the corrosion in this pipe could ‘result in a catastrophic failure, leading to the release of raw sewage into the soil, groundwater and waterways.’ That is literally what happened.
What is the Park Service saying, and what is D.C. Water saying?
- Aaron Davis:
The Park Service tells us that they could never really begin to evaluate this because D.C. Water kept changing the plans, and that kept starting over the environmental process. And so it was really D.C. Water’s fault.
D.C. Water has been very careful in saying, ‘We’ve been following the Park Service’s direction and we’re trying to do and accomplish what they want.’
D.C. Water is in kind of a tough spot here, because so much of their infrastructure is on federal park land, and so they often need the approval of the National Park Service to do any construction on their own lines.
- Nick Iannelli:
In looking through these documents and the information from D.C. Water, as it relates to this specific portion of pipe that collapsed, is there any other information that would suggest that there are other parts of the pipe that are vulnerable to this sort of thing?
- Aaron Davis:
There’s a concerning slide that some of the engineers inside D.C. Water presented to the executives back in November of 2024, so this is a little over 18 months ago. And if you look at that map, which is the 50-mile-long Potomac Interceptor that stretches all the way out to Dulles Airport, there are a lot of sections that are either in orange or in red. And those two sections, by the color-coded system, are worse than the spot that ruptured back in January.
The spot that ruptured in January was listed as having a ‘moderate’ defect from corrosion. The other parts we’re seeing, there’s at least one spot in those other sections that is either rated as ‘very significant’ or ‘critical.’
There are many other places that are corroding inside the Potomac Interceptor, and you couple that with what the utility has said publicly since the disaster, which is that they’re now wondering if there are big boulders buried on top of other parts of the line that could create pressure points and lead to that kind of failure like what we just saw.
They were actually lucky that the rupture happened where it happened, because just a few 100 yards away was the C&O Canal that they could use as an open-air sewer and temporarily divert things. There’s a whole lot of stretches through Virginia, and even under the Potomac River itself, where there is no other redundancy, there’s no other canal they can put the sewage into. It ended up taking 54 days to repair that pipe this time.

The National Capital Planning Commission voted unanimously Thursday to approve preliminary site and building plans for the new Washington Commanders stadium at the former RFK Stadium site in D.C.
But members raised questions and concerns about the redevelopment project’s two planned parking garages.
“The stadium looks beautiful right now, but as I’ve said previously at NCPC meetings, I have rarely have ever seen a beautiful parking facility,” NCPC Chair William Scharf said. “So I think understanding how that affects the overall project plan and what the stadium will actually look like to people once it’s complete, I think, it’s really important.”
The overall project includes as many as 8,000 parking spaces, with 75% of them in the garages and 25% in surface lots as of the stadium’s opening day.
At 11 stories high, the two garages could be nearly two-thirds as tall as the stadium itself. A map of the site shown at the Thursday meeting indicated the structures could also be as large or larger than the nearby D.C. Armory.
In renderings presented at the meeting, the garages are pictured in a few of the images, but are not the focus. In one image, the garage is transparent to better show off the stadium’s east side. In another stadium view, a garage fades into the background.
Commission staff member Laura Shipman said the parking garages will be developed independently from the stadium and will be separately submitted for commission approval.
One commissioner questioned the garages’ omission from the preliminary stadium site plan, but still voted to approve it.
“Help me understand why we’re not seeing the development of those (garages) with the stadium package,” said Tammy Stidham, an NCPC commissioner and National Park Service lands and planning director. “They don’t have independent utility. They would not be there if you were not building a stadium.”
NCPC staff also recommended that “alternative orientations” and lower garage heights be considered to reduce visual impacts of views to the stadium, from Kingman Park and from other adjacent neighborhoods.
“I appreciate the sincere interest each one of you all have shown in this garage problem, because it is truly a problem and it throws off the scale,” said Kingman Park resident Frazer Walton.
Walton spoke on behalf of the Friends of Kingman Park Civic Association, which he said supports the stadium redevelopment project, but opposes the construction of a parking garage next to the neighborhood for health and traffic reasons.
“The alternative would be that you not build these massive parking garages, multilevel garages, and that we focus on increasing the size of the Stadium-Armory Metro site,” Walton said. “We also suggest that we build a new subway stop at Oklahoma and Benning Road within the next five to seven years.”

Washington expands oversight of healthcare ownership transactions
In March, The Washington State Legislature enacted HB 2548, expanding state oversight of healthcare ownership transactions and requiring new disclosures when hospitals and provider organizations change hands.
Washington already requires hospitals, hospital systems, and provider organizations to give the Attorney General at least 60 days’ notice before certain transactions that result in a material change, so the Attorney General can evaluate whether an antitrust investigation is warranted.
HB 2548 broadens those notice triggers to include:
- changes in majority ownership or control of a hospital, hospital system, or provider organization;
- acquisitions, sales, or transfers of a majority of an entity’s assets, including real estate sale-leaseback transactions; and
- conversions of nonprofit healthcare entities into for-profit corporations or unincorporated entities.
The bill also adds ownership disclosures, filing fees scaled to the transaction’s value, post-transaction notification within 30 days of a deal being completed, and quarterly public notice of pending and completed transactions on the Attorney General’s website. It also requires transactions to pause until 30 days after the parties certify substantial compliance with any request for additional information from the Attorney General.
The law does not expand the Attorney General’s authority to block or unwind transactions beyond existing antitrust law, but instead strengthens notice, disclosure, and investigatory capacity.
Private equity in Washington
The legislation comes amid growing concern about consolidation and investment activity in Washington’s healthcare sector.
In its December 2025 annual report, the Washington Health Care Cost Transparency Board stated that when healthcare organizations are acquired, merged, or affiliated with private equity, patient prices and healthcare spending go up, driven by increases in provider fees, hospital prices, drug prices, and insurance premiums. The board also noted that consolidation leads to fewer patient choices and decreased or unchanged quality of care, slower wage growth and worse working conditions for healthcare workers, and hospital closures linked to delays in care and increased mortality.
On private equity specifically, the board flagged Washington’s substantial growth in private equity ownership over the past decade and noted that private equity firms often acquire additional nearby practices after an initial acquisition, laying the groundwork for further consolidation
A January 2026 report from the Washington Office of the Insurance Commissioner documented 551 healthcare acquisitions in Washington since 2015, with deal values peaking at $11.3 billion in 2023 and transaction volume peaking at 111 deals in 2021. Nationally, private equity investors spent more than $200 billion on healthcare acquisitions in 2021 alone and $1 trillion over the past decade. The most heavily targeted sectors in Washington by deal count were veterinary, dental, mental health, dermatology, musculoskeletal, vision, and gastroenterology, while veterinary care dominated by total deal value.
Earlier efforts at oversight
HB 2548 comes after earlier legislative proposals in Washington to establish more comprehensive oversight of healthcare transactions.
In 2025, Washington legislators introduced HB 1881, the Keep Our Care Act, which would have amended state law to prohibit any merger, acquisition, or contracting affiliation among hospitals, hospital systems, or provider organizations that would “detrimentally affect the continued existence of accessible, affordable health care in Washington state for at least five years after the transaction occurs.”
The Washington Health Care Authority would have had authority to conduct a formal review of each covered transaction – including at least one public hearing – and submit a report and recommendation to the Attorney General, who would have authority to approve, conditionally approve, or disapprove the deal outright. The bill was referred to the Committee on Civil Rights & Judiciary, where it did not advance.
While comprehensive transaction oversight stalled last year, the legislature did take a step toward greater transparency. Last April, the governor signed HB 1686 into law, requiring the Department of Health to develop a plan for a complete interactive registry of Washington’s healthcare landscape, including the ownership, investment, and governance structures of healthcare entities. DOH must deliver a progress update by December 31, 2027, and a final report with implementation recommendations by November 1, 2028.
A step towards more transparency
HB 2548 expands Washington’s healthcare transaction notification framework to include a wider range of ownership changes, asset transfers, and organizational conversions, while increasing disclosure requirements and public reporting.
The law does not alter the Attorney General’s underlying authority to review or challenge transactions, but gives regulators access to more information under existing legal standards.
The changes in HB 2548 give regulators earlier notice and more detailed information about consolidation activity across the state’s healthcare system, positioning Washington to more effectively monitor consolidation trends, including activity by private equity and other profit-driven actors.
