Leeuwarden, the Netherlands-based Hydraloop, a company specialised in recycling grey water, announced on Wednesday that it has closed €10.5M in a Series B round of funding out of €13.5M.
Impact investors, including Invest-NL, and NOM, as well as proptech investor Amavi Capital, participated in the round.
The company will use the fund to scale up its global B2B sales and develop strategic partnerships.
To date, Hydraloop has 130 partners in 35 countries, installing water recyclers in residences, hotels, sports facilities, student housing, and other high water usage buildings.
“We are proud that Invest-NL has become a shareholder of Hydraloop,” says Arthur Valkieser, co-founder and CEO of Hydraloop.
“It’s time for scaling up and international growth. Worldwide, water scarcity is leading to changes in the way people manage water. Governments are quickly implementing measures to encourage or mandate greywater recycling. For example, in Florida, companies can claim the costs of a water recycler on their taxes. Spain offers a 70% subsidy for hotels and campsites that want to recycle greywater. And in parts of England, a building permit is only granted if there is a water-saving system in the house. In the Netherlands, many new residential areas can only be built if they implement water-saving systems, such as greywater recycling. We foresee that in 10 to 15 years, every new building will have its water recycler,” adds Valkieser.
This is Invest-NL’s third impact investment in the last two days after Innatera and Effect Photonics.
Birth of Hydraloop
Arthur Valkieser founded Hydraloop because he believed it was ridiculous to use precious water to flush toilets in the 21st century when water is becoming scarce.
After installing one of the prototypes of a decentralised water recycling system in his home, he became invested in water recycling.
Valkieser invested years in research and development to design an affordable and compact device that’s easy to use and requires low maintenance.
The main objective was to create a system that significantly reduces water consumption without sacrificing personal hygiene and living comfort.
After months of work, the Hydraloop was finally ready for market launch in November 2017.
Hydraloop: What you need to know
Hydraloop’s technology is the world’s first IoT-connected water recycling system that reduces total in-house water consumption by 25-45 per cent.
The company’s products can be used everywhere: in dense cities, rural areas, and off-grid situations where water supply is unstable or insufficient.
Currently, the company offers products in four variants:
- Hydraloop H300 – For homes and apartments
- Hydraloop H600 – For larger homes and small businesses
- Hydraloop Concealed – For smaller homes and retrofit bathrooms
- Hydraloop Cascade – For larger buildings
A Hydraloop device collects and cleans greywater from various sources, such as showers, baths, washing machines, and condensation water from dryers, heat pumps, and air conditioning.
The greywater treatment combines six technologies: sedimentation, flotation, dissolved air flotation, foam fractionation, an aerobic bioreactor, and disinfection of the treated water with powerful UV light, inactivating all pathogenic microorganisms.
The treatment process removes hair, dirt, soap, and other pollution from greywater without the use of filters, membranes, or chemicals.
The treated water can be reused for a wide range of non-potable applications such as flushing, washing machines, and irrigation. The company says the reused water is clean, safe, and disinfected.
Its water meets the highest international standards, like the US NSF-350 and European EN-16841.
Lars Groeneveld, Senior Investment Manager at Invest-NL, says, “In pursuing a sustainable future, we recognise the importance of innovative solutions for the global water crisis. The investment in Hydraloop represents more than just financial support; it’s a commitment to preserving our most precious resource: water. Hydraloop’s revolutionary technology offers a concrete solution for more sustainable water use, and we are proud to contribute to this.”
