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 wastewater. 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. It also has the function to sterilize the surface of smartphones by over 99.9%, contributing to public space hygiene. The company also offers WOTA PLANT, a cloud-based data management service focused on collecting, analyzing, and coordinating data for water treatment plants, digitizing, and "smartening" existing "dumb" facilities.
