WOTA

WOTA is developing small-scale decentralized water reuse systems and autonomous control systems for water treatment. Their first product, WOTA BOX, launched in November 2019 as a portable water reclamation treatment plant that can recycle and reuse more than 98% of domestic greywater. In a device that is only 0.25 cubic meters in size, it enables continuous water use in situations where there is no water supply (such as when water is cut off due to a disaster). Their second product, WOSH, is a water circulation hand washing machine that can be installed where there is no running water, contributing to public space hygiene. They are currently developing their third product, WHK, the world's first, household-scale, decentralized, water recycling system that recycles all household wastewater to potable quality, on-site.
