A story about a man who swims to work went viral. Here’s what makes his commute possible.

Benjamin David lives in Munich, and he swims to work.

Every morning, David checks the velocity and temperature of the water…

…puts on his swim trunks and packs his dry container with the clothes and gear he needs for the day…

American cities are pushing for river ponds too. For seven years, a nonprofit in New York City has been working on + POOL, a floating swimming pool in the shape of a plus sign that they are able filter impurities through its walls. They have a bevy of backers and great designs but are currently in a holding pattern with the city, waiting for a site to install it.

One city that’s watching the benefits of returning the river to swimmers is Portland, Oregon.

The city is split in half by the Willamette River, a thoroughfare still used to export grain and dry-dock ships. But despite Portland’s eco-friendly persona, the river was long neglected and prone to sewage overflows. With its implementation of the Big Pipe, a sewage infrastructure project, the Willamette has been remarkably clean and safe for swimming . Yet it was still hard to persuade residents to dive in.

That’s where local nonprofit group Human Access Projectcomes in. The group of volunteers seek its mission of transforming Portland’s relationship with the river by creating public spaces like access points and beaches, supporting education and preservation efforts, and, of course, leap in for a dip. The HAP hosts the Big Float a floating party in the river an annual river swim with Mayor Ted Wheeler, and even has a swim team called the River Huggers . Yeah, severely.

“For us, swimability is a platform for hope, ” tells HAP Founder and Ringleader Willie Levenson. “Our hope is that if we can reconnect people with the river through their own self-interest, through something that will benefit them being able to get into the water and swimming they will naturally care more about the outcomes of what’s happening in the watershed. They’ll naturally be more inclined to fight for this thing that they love and enjoy.”

Are swimmable rivers and lakes not on your city’s radar? There’s still a lot you can do.

While most people don’t have the time to found and coordinate their own nonprofit like Levenson, there are similar groups like the Waterkeepers or your local watershed council that are already doing this work. Donate your time or make a contribution to keep the good going.

You can also start using the body of water to swim, kayak, or relax. It’s fun, affordable, and close to home. Check the water quality exam results online before jumping in, and bring a friend or swimming buddy. Let your local elected officials know you want safe access to your water and subsistence candidates that make it a priority.

You may not use it to commute, like David, or create a float party with thousands of your closest friends, like Willie Levenson, but it’s your community and your water, and you deserve a clean, safe place to enjoy it.
