Hydraloop
Hydraloop is a Dutch water technology company that makes compact, in-home and in-building water recycling systems. Its certified, chemical-free devices collect and clean up to 85% of a household's water - from showers, baths, washing machines and air-conditioning condensation - and return it for toilet flushing, laundry, garden irrigation and pool top-up, cutting fresh water use and sewage output by up to 45%. Founded in 2015 by Arthur Valkieser and Sabine Stuiver, the company won CES 2020's 'Best of the Best' award and a 2022 UN WIPO Global Award, and sells decentralized greywater systems to homeowners, developers and the hospitality sector worldwide.
Epic Cleantec
Epic Cleantec is a San Francisco cleantech company that builds onsite water reuse systems for buildings, letting towers and campuses recycle up to 95% of their own wastewater into clean non-potable water, recovered heat energy, and organic soil products. Its OneWater platform installs treatment in the basement so showers, sinks, and laundry water get reused on site instead of flushed to a distant plant. The company got famous for turning recycled building water into commercial beer, and it counts high-rise developers as its core customers.
