In the middle of the Arizona desert, where you’d expect dust, cactus, and maybe a few roosters, a small group of builders has created something no one thought they’d find there: a private wave pool called The Wave Source.

Pro surfer and YouTuber Ben Gravy was the first outsider invited to test it.

“I got a message on Instagram that just said, ‘Call me. We have a backyard wave,” he recalled.

At first, he ignored it. A follow-up note explained, “It’s our first prototype. We’d love your opinion.”

A phone call and a signed non-disclosure agreement (NDA) later, Gravy was on the road from California to rural Arizona.

When he arrived, it was far from tropical. The desert morning was about 45 °F (7 °C), cold enough to see your breath.

The pool sat inside a compound “in the middle of nowhere,” he said.

But what waited out back was a working surf machine built without contractors, designed with nuclear-grade parts, and designed to be affordable and efficient.

Four Months to Build, No Contractors

The Wave Source was built by a small team led by Tony, Justin, and Ash.

Tony came up with the idea after seeing Kelly Slater’s famous Surf Ranch wave. As he explained, Slater’s version was groundbreaking but too expensive to run.

“That set my goal to make waves economically that everybody could surf,” Tony said.

From start to finish, the Arizona build took about four months. No outside crews were hired.

“It was just us,” one of the builders explained.

The system relies on off-the-shelf parts – the same kind used in nuclear reactors.

Ash, who also runs a manufacturing company, stressed that downtime kills a business. If the system broke, he wanted it fixed in a day.

And that’s how it worked: when a component failed, he simply drove into town, picked up a replacement, and had the pool running at 50 percent capacity until it was fully restored.

The whole pool runs completely off the grid, with no tie to city power.

Software, Hardware, and Barrels

Tony and Justin teamed up on the design, which kind of reminds us of a blend of American Wave Machines’ PerfectSwell with Whitewater’s Endless Surf technology.

Tony laid out the mechanics of how he wanted the system to work, while Justin wrote custom software to control the waves.

Once Ash and Ryan built the pool in the backyard, they filled it, crossed their fingers, and pushed the start button.

Within an hour, the first wave appeared, exactly as predicted by their computer models.

The team started with a signature ride and named it. Later, they worked with Ben Gravy to tune in a barrel section.

Over two days, he surfed, gave feedback, and watched the engineers tweak controls in real time.

By the end, the pool was spitting out hollow, rideable barrels. “You’re the first one to ride the barrel,” the team told Gravy.

Laughing, they nicknamed it “Barrel Makes Gravy.”

Efficiency and Possibilities

According to the builders, the pool uses two-thirds less electricity than other commercial wave pools. And because the design is modular, new waves can be programmed on demand.

Some waves are designed to be user-friendly for beginners, while others aim for high performance.

The system’s reliability is rooted in the builders’ backgrounds.

One engineer on the project previously worked in failure analysis for rockets, where breakdowns are not an option.

That same mindset guided the design of the Arizona pool.

A Private Desert Surf Ranch

For Gravy, paddling into waves in Arizona felt unreal.

“Imagine, did I ever think the day would come that I’d be in someone’s backyard in Arizona, enjoying a private wave pool all to myself?” he asked.

“This is unbelievable. It’s truly unbelievable.”

The Wave Source remains private, with no official name for the pool itself beyond “the backyard.”

But with custom software, off-grid power, and a dream turned into a functioning prototype in just four months, it’s already being called by some the “eighth wonder of the world.”

Maybe this is the start of something new for anyone wishing to build in their terrace or courtyard.
