Dutch Hydraloop lets the world use its water twice

By 2030, 1.6 to 2.8 billion people will not have access to clean drinking water, according to UN agencies Unicef ​​and the WHO. Now ‘pure’ can not always be drunk, for every holidaymaker knows that it is better to drink bottled water south of Paris than from the tap. Yet, in dry periods, less and less water is coming out of the tap worldwide.

Day Zero is coming

During dry periods in South Africa, the inhabitants of Cape Town are only allowed to take a bath for two minutes, and Day Zero – the day when there is no more tap water – is approaching. In a southern French village, it was forbidden to brush teeth with tap water during this heat wave.

In the counties of England, Suffolk and Kent, residents were only allowed to use drinking water for essential purposes during that period. But clean drinking water is also coming under increasing pressure in the water-rich Netherlands. Drought causes the groundwater level to fall or the water level in the rivers to fall as they are now.

Let’s get our drinking water out of it. For example, the water company Vitens warned this year that the supply of drinking water in Overijssel will come under pressure. It also rejected new drinking water applications for businesses in May. So in heat waves and dry periods, there is a call to shower less, not to water the garden and not to fill baths.

Save 45 percent water

You can also save water by recycling water at home, said inventor Arthur Valkieser, now CEO of Hydraloop. He devised a patented technique without filters, membranes or chemicals that can reduce water consumption in homes and buildings by 45 percent.

His Hydraloop looks like some kind of big fridge. The unit is connected to drains of showers, baths, washing machines, condenser dryers, sinks and air conditioners. That water usually disappears into the sewer. After disinfection and cleaning, the water can be reused as rinsing water for the toilet, washing machine or watering the garden.

According to the company, the number of extra pipes to be added to this is not that small. Water from toilets and kitchens, such as sinks or dishwashers, is not recycled. “We do not do anything about it, because it is too greasy and contains too much leftover food to clean. The Hydraloopen also does not supply drinking water. That’s why we call it gray water, ”explains spokeswoman Barbara Mounier.

“Ultimately, we collect 85 to 90 percent of the water in the house for recycling. So if you use it twice, you save 45 percent on your total consumption. ”

Breakthrough in Las Vegas

Valkieser launched its first Hydraloop in 2017. The big breakthrough came when the device was unveiled at the CES show in Las Vegas in 2020 and won several awards in innovation and sustainability. This attracted the attention of several parties.

Hydraloop became famous when it was mentioned as one of the solutions to the global water crisis in the Netflix documentary ‘Brave Blue World’, starring Liam Neeson and starring Matt Damon and Jaden Smith. Hydraloop now has 120 partners in 50 countries who sell, install and maintain the device. Thousands of units have already been sold worldwide this year, and it goes to tens of thousands. In addition to the head office in Leeuwarden, the company has offices in the United States and Dubai. These are important sales markets.

The water company pays

Hydraloop is attracting more and more customers, especially in the Middle East. “It’s one of the driest regions in the world. They invest a lot of money there in desalinating seawater. It’s expensive and gives an ugly residue. We say: If you spend that much money on your water, spend it twice. “However, not all skyscrapers in Dubai are equipped with a Hydraloop yet. The company has only been active in the city for a year and focuses mainly on new construction.”

In South Africa – where water shortages are getting worse – the company is working with a project developer who is building a new neighborhood in Johannesburg for the black middle class. These houses will have a Hydraloop. In Australia, the company has partnered with Sydney Water to help households save water. “They pay for the installation in the homes. This ensures that the company can continue to supply water, ”says Mounier. To accommodate all of these types of projects, the company is rapidly scaling up to produce more units.
