Dutch invention Hydraloop on the rise after success at CES tech fair

Use less water. We all have to believe in it in times of water scarcity, a growing world population and climate change, they know at Hydraloop in Emmen.

If we continue our consumption like this, by 2040 there will not be enough to quench our thirst, a 2014 study by Aarhus University in Denmark showed.

And that while the dirty water from our shower or washing machine can be recycled perfectly. Just in your own home or office. Not for drinking, but for flushing your toilet, watering plants or filling a swimming pool, for example.

The idea for a water recycler already existed, inventor Arthur Valkieser previously told RTL Z. But nobody had made a product of it yet. He built the Hydraloop, a kind of ‘refrigerator’ that, in his own words, recycles up to 95 percent of your shower water and can save you about 45 percent of tap water. The first version came on the market in 2017.

The invention was greatly appreciated three years later and received awards at the Consumer Electronics Show (CES). “Best of the Best,” was the verdict. Time magazine named Hydraloop one of the show’s twenty-five best products. “I still get goosebumps just thinking about it,” says co-founder Sabine Stuiver now.

‘Email box explodes’

They owe a lot to this large scholarship, says Stuiver. At the time in 2020 there were five of them, a small startup from the Netherlands. “We now have an office in Leeuwarden, in the US and in the Middle East. We are thirty people, still without production employees.”

After all the attention in Las Vegas, her email exploded. “There is no language in which we have not been written or talked about,” says Stuiver. “CES was a global launch for us, a tipping point for our company.”

Without the attention, the company would also have grown, says the founder. “But it hadn’t gone so fast.” The Hydraloop is now sold in fifty countries by local sales partners, says Stuiver from its own production facility in the Netherlands. “Water scarcity is everywhere”, even in the Netherlands.

Entry-level

The ‘entry-level’ model of the Hydraloop, with a capacity of 300 litres, costs around 3000 euros. However, the company is now also working on smaller versions that can be placed in the bathroom, for example, and large versions for hotels, for example.

It is a considerable investment, also because the price for drinking water in the Netherlands is about 0.87 cents per cubic meter, excluding fixed costs and taxes. So it takes a while to get that out. “This is tech for good,” says Stuiver. “We are a do-gooder.”

Reroute pipelines

In principle, the system can be connected in all kinds of places, but pipes must be laid or diverted for it. According to the company, this is not a complicated job. Hydraloop has no filters and, according to the company, requires relatively little maintenance.

“You can compare it with a central heating boiler: you install it and then you don’t have to worry about it for a long time”, Valkieser said earlier.
