New water fountains and refill stations are coming to the Mount Vernon Trail, the U.S. Marine Corps War Memorial and other federally controlled parts of Arlington.
The National Park Service plans to install up to 14 new stations at “high-priority locations” in the vicinity of GW Parkway.
An online map depicts locations near the Roosevelt Island pedestrian bridge, north of the Mount Vernon Trail’s Navy and Marine Memorial, and elsewhere along the eastern edge of Arlington, plus other locations north and south of the county.

The new water fountains will replace equipment that is up to 30 years old. They’ll include dual drinking fountains, a water bottle filling option and a bowl near the ground for thirsty pets.
“Many of the park’s existing drinking fountains are outdated and shut down during colder months,” the Park Service said in a news release. “The new stations are built to withstand freezing temperatures and remain in service year round.”
Currently, two of the new stations are up and running — one along the Mount Vernon Trail near Alexandria Avenue and one on Roosevelt Island.
“Whether you’re biking the Mount Vernon Trail, exploring historic sites, or walking your dog at one of our parks, having access to clean, reliable drinking water makes every visit safer and more enjoyable,” GW Parkway Superintendent Jennifer Madello said.

All 14 are expected to be in place some time in 2026, but the Parkway plans to hold an official ribbon cutting ceremony to celebrate the new features and thank sponsors in October.
Park officials hope the new stations will promote reusable bottle use among runners, walkers and bikers.
“By expanding access to drinking water and encouraging reusable bottles, this project supports the park’s mission to protect the Potomac River corridor while serving millions of visitors each year,” the Park Service said. “Whether you’re biking the Mount Vernon Trail, walking your dog at Belle Haven Park, or exploring Fort Hunt with your family, we encourage you to bring a reusable bottle and help protect your park.”
