Army Corps: Reservoir expansion ‘doesn’t fix, but improves’ DC’s drinking water supply for future Potomac River emergency – WTOP News

Developing a regional solution to enable all local water companies to share drinking water in the event of a future Potomac River emergency remains a long-term challenge facing the U.S. Army Corps of Engineers. But the Corps is leaning-in to near term solutions, for now, because current issues “are quite, quite dire.”

In an interview with WTOP, Trevor Cyran, Chief of the Civil Works project management office of the Baltimore District Corps of Engineers, elaborated on the Corps’ ongoing three-year feasibility study funded by Congress and the Metropolitan Washington Council of Governments.

Last week, during a House Transportation and Infrastructure Committee hearing, lawmakers pressed the U.S. Army Corps of Engineers to explain what’s being done to secure solid backup options for the D.C. region’s drinking water.

D.C. Del. Eleanor Holmes Norton challenged the Corps after learning that the study that Congress authorized to identify a secondary water source for the region was being narrowed to only expanding the current Dalecarlia Reservoir, adjacent to the Washington Aqueduct, which remains the only source of drinking water for D.C., Arlington, and parts of Fairfax County, Virginia.

“Expansion of the reservoir is not a secondary water source,” Norton said. “With only a one day of backup water supply, human-made or natural events that make the river unusable would put residents, the District government and the regional economy at risk.”

Cyran said the U.S. Army Corps of Engineers doesn’t disagree.

“We’re trying to find a quick win that addresses some of the near-term issues, because they are quite, quite dire,” Cyran said. “The Dalecarlia expansion would add approximately 12 hours of water storage into the system,” he said. “So, while we know that doesn’t fix the problem, it improves the situation.”

Recently, drinking water in D.C., Northern Virginia and Maryland has remained safe because the January collapse of a portion of the aging Potomac Interceptor regional sewer line happened downstream of the main Potomac River water intake serving the Washington Aqueduct.

“We’ve moved forward with the Dalecarlia expansion, as our most probable recommendation,” said Cyran. “The Corps is laser focused on delivering something right here, right now that can actually help with the issue, while still exploring some of those long term solutions.”

Cyran said the dangers to public health and the economy are substantial, with the Potomac as the sole drinking water source. “It’s not a great situation — we’ve seen a very real risk come to fruition recently, with the spill.”

While drinking water has been unaffected by the spill, the advisory for the public to avoid contact with the Potomac River remains in effect in the District and Montgomery County, where the Potomac Interceptor spill happened, along the Clara Barton Parkway.

The advisory is expected to be lifted Monday, by the D.C. Department of Health, as E. coli levels have recently returned to the typical range for D.C.’s rivers. The District’s Department of Energy and Environment is now doing daily testing of the Potomac and Anacostia Rivers.

How would increased storage at Dalecarlia Reservoir look?

According to the Army Corps, expanding the Reservoir over 54 available acres would provide approximately 70 million gallons per day, doubling the capacity at Dalecarlia. Since the land is already owned by the Washington Aqueduct, it would not require acquiring any land.

Cyran said it’s not yet certain whether the expansion would provide an extra 12 hours of storage of raw water from the Potomac, or finished water, after it had gone through the Washington Aqueduct’s water purification process.

Regardless, either option would result in the Aqueduct having more water on hand, if drawing water from the Potomac was suddenly unsafe.

Another near-term option that wouldn’t require land acquisition would be advanced treatment, Cyran said.

“We could implement something that allows us to treat for a wider array of contaminants, if you had a spill,” said Cyran, although noting the recent spill from the Potomac Interceptor, which poured approximately 240 millions of raw sewage into the Potomac, “might not be a good example” of how the technology would work.

The Army Corps list of possible solutions includes reusing water. In November 2025, DC Water outlined its own plans to recycle water from the utility’s Blue Plains Advanced Wastewater Treatment Plant, the largest of its kind in the world.

Quarry storage cannot happen quickly

During its ongoing study, the Army Corps has identified possible long term regional solutions, including the potential use of the Travilah Quarry in Montgomery County, Maryland, and two quarries in Loudoun County, Virginia, owned by Luck Stone.

10 years ago, in December 2016, WTOP first reported that the Travilah Quarry, located on Piney Meetinghouse Road in Rockville, was quietly being considered by DC Water, WSSC Water, and Fairfax Water, as an alternative source of water, if the Potomac River were unavailable.

“The three utilities, and the Interstate Commission on the Potomac River Basin, along with the Metropolitan Washington Council of Governments have been working over the last several years to look at alternatives to get better interdependencies, to have more resilience in our system,” said Tom Jacobus in 2016, while he was general manager of the Aqueduct.

Now, a decade later, the logistical, real estate, and financial challenges of obtaining a quarry which could be interconnected between DC Water, WSSC Water, and Fairfax Water remain.

“We’re not saying they can never happen, we’re just saying they cannot, in any way, shape, or form, happen quickly,” said Cyran. “Travilah is still an active quarry, so that can’t even be considered for storage until they’re done mining, which might be 30 years from now.”

The Dalecarlia Reservoir expansion would not be regional solution, Cyran said.

“That would only benefit folks who are tied directly to the Aqueduct at this time,” he said. “However, while we’re going to be looking at other alternatives that we could potentially spin off and continue to look at, that would address some of those more regional issues.”

‘We can’t hand half-baked ideas to Congress’

While an interconnected, resilient system, that could provide additional water sources and storage to DC Water, WSSC Water, and Fairfax Water would be optimal, Cyran said the Corps is limited by a Congressional paradigm that limits its feasibility study to four years and five million dollars.

“We can’t hand half-baked ideas to Congress,” Cyran said.

With the Corps’ current focus of implementing near-term improvements, quickly, the agency will continue to use its expertise to envision a more resilient, long term solution.

“We are committed to looking at this issue and try to explore some regional solutions, within the paradigms of the legislation that we have to operate within,” said Cyran. “If Congress wants to consider something else to expand our authority, we could maybe look at a bigger solution, with more time and money.”

Lime updates subscription service for frequent riders in DC – WTOP News

Lime, the company behind those bright green scooters and bikes you may often see zooming around D.C. or lying on the sidewalk, is updating its monthly subscription service, aimed at making rides more affordable for its frequent users.

In a news release Tuesday, Lime said its monthly subscription that starts at $5.99/month for D.C. riders will also introduce flat-rate pricing of $2.50 for rides up to 20 minutes and $1.25 for rides under five minutes.

Every ride will be subject to a flat rate, instead of a per-minute cost. Subscribed members also get unlimited free unlocking and discounted flat-rate pricing for trips under five minutes.

Devin Rote, the global integrated marketing lead at Lime, told WTOP the goal with the update is “to make the choice to utilize micro-mobility and more sustainable travel options easier for users across the D.C. region.”

Rote said as we enter the spring season, Lime sees an increase in trips as the city also sees a rise in tourism.

“Especially through cherry blossom season, Nationals baseball season, and everything that a great, warm weather season brings here in the D.C. region. For us, really, this is the start of busy season,” he said.

There are over 7,000 of the dockless e-bikes and scooters around D.C. They go up to 18 mph — down from 20 mph in November — and users must be at least 18 to ride.

WTOP’s John Wordock contributed to this report.

A Virginia boater is suing a DC utility for the Potomac River sewage spill

A Virginia boater is suing a DC utility for the Potomac River sewage spill

A Virginia boater is suing a Washington water utility for negligence in the collapse of a pipe that leaked millions of gallons of raw sewage into the Potomac River.

The class action lawsuit filed Friday in U.S. District Court in Greenbelt, Maryland, comes weeks after a January sewage pipe collapse, shooting wastewater out of the ground and into the river in an area just north of Washington, D.C. The spill is seen as a serious environmental blight and became the focus of political bickering between President Donald Trump and Democratic-led Maryland, where the leak occurred.

Dr. Nicholas Lailas, M.D., the plaintiff, is a Virginia resident and recreational boat user on the Potomac who is seeking compensation for people “whose property interests in and use and enjoyment of the Potomac River … have been impaired by Defendant’s conduct.”

The lawsuit alleges that it was DC Water’s responsibility as the owner and operator of the ruptured pipe, known as the Potomac Interceptor, to maintain it in a “reasonably safe condition and to prevent foreseeable harm to persons and property.”

The lawsuit said that preliminary data indicate that there are thousands of people who own property or vessels in the affected parts of the Potomac.

Andrew Levetown, an attorney for the plaintiff, said in an interview Monday that it will take time to get the full breadth of the class, with business owners, property owners and recreational users all having interest in the potential damages caused by the Jan. 19 collapse and leak.

“You’re going to have businesses who lose business because instead of sitting next to the Potomac, their clients are sitting next to the open sewer,” he said.

The suit did not specify a damage amount. DC Water spokesperson John Lisle said in a statement that the collapse of the Potomac Interceptor was “a serious and unexpected event, and our teams remain focused on the response, environmental protection, and restoration efforts. Because this matter is currently subject to ongoing litigation, it would not be appropriate for us to comment further at this time.”

D.C. Mayor Muriel Bowser declared an emergency Feb. 18 and requested that President Donald Trump provide federal resources to help the city fight the leak that dumped 250 million gallons of raw sewage into the Potomac River in its early stages. The president approved the emergency assistance days later to help the city address the emergency.

DC Water gave its most detailed assessment yet of why the Potomac River sewage spill occurred and what it will take to fix it. News4’s Mark Segraves reports.

DC Water said it knew the pipe, first installed in the 1960s, was deteriorating, and rehabilitation work on a section about a quarter-mile (400 meters) from the break began in September and was recently completed. The pipe that ruptured was scheduled for repair this summer.

DC Water’s updates say the emergency repairs are beyond the halfway point and there are no flows into the river.

At a public briefing last week, officials with the utility said they were assessing the cause of the rupture, including whether the way the pipeline was initially constructed contributed to the emergency. David Gadis, the CEO of DC Water, said at that briefing that while it was too early to say definitively, “we are seeing indication that this incident may have been highly unusual.”

Route for Freedom 250 Grand Prix in DC debuted at the National Mall

WASHINGTON — Get ready to start your engines, DC.

Officials unveiled the 1.66-mile circuit route Monday, where race cars will be zooming around the National Mall in August for the Freedom 250 Grand Prix in celebration of America’s birthday.

The seven‑turn layout features views of the Washington Monument, US Capitol, the Smithsonian National Air and Space Museum, and part of Pennsylvania Avenue, IndyCar announced.

“This was a team effort,” Transportation Secretary Sean Duffy said. “It’s Penske, it’s FOX, it’s the mayor, it’s Interior, it’s everybody else joining together not to make a profit, not to get your name out there but to say, let’s celebrate America.”

“Let’s celebrate America’s birthday.”

The first-ever street race around the National Mall will take place from Aug. 22-23, with the course itself set to be built up during the summer.

Drivers will also blast past the National Archives, the National Gallery of Art, and the Hirshhorn Museum, with a pit lane on Pennsylvania Avenue.

Officials debuted a red, white, and blue “Freedom 250 Grand Prix IndyCar” design Monday to honor the upcoming 250th anniversary of the adoption of the Declaration of Independence.

“We want people to plan their trips to D.C. now,” DC Mayor Muriel Bowser said. “Come for the Freedom 250, and then stay to enjoy our monuments and museums, our beautiful parks, world-class restaurants and hotels, and all the culture and entertainment that make us the best city in the world.”

President Trump took executive action back in January, tasking Duffy and Secretary of the Interior Sean Duffy to coordinate with Bowser on planning the feted event.

“The story of America is one of vision, courage, perseverance – and speed,” Monica Crowley, Trump’s representative for America’s 250th, said in a statement.

“Presidents Washington and Jefferson marked notable celebrations with spirited horse races; the Freedom 250 race will bring that historic tradition into the 21st century and renew a tremendous sense of patriotic pride.”

Trump’s team is eyeing other major sports events to celebrate America’s 250th anniversary, including a UFC fight at the White House. The US is also co-hosting the 2026 FIFA World Cup over the summer.
