【Sustainable Japan Excellence Award】Wota Corp.
Representative Director & CEO
Our company aims to provide structural solutions to water problems. Since our founding in 2014, we have been developing our small-scale distributed water recycling system that recycles and makes maximum use of wastewater, as well as our technology for automated control of water treatment, which makes this possible, in order to solve various problems caused by uneven distribution, depletion and pollution of water resources around the planet.
Our system enables water use without relying on access to standard water and sewage services, such as during water outages caused by natural disasters.
During the 2018 floods in western Japan, we responded to water outages by using a prototype of our water-recycling shower, Wota Box, and have been promoting mass production since then, providing support for bathing and hand-washing in multiple disaster-affected areas.
After the Noto Peninsula earthquake early this year, we provided nearly 100 Wota Box units and 200 Wosh hand-washing stands, covering about 89% of evacuation centers and 68 hospitals and care facilities affected by long-term water outages. We are still providing bathing and hand-washing support in areas where water has been cut off.
We are also developing and conducting demonstration tests of our small-scale distributed water recycling system for residential use. By introducing this system, the need for water supply piping can be eliminated, leading to improvements in the fiscal sustainability of water and sewage services in depopulated areas and providing a sustainable water supply solution. This system can also adapt flexibly to changes in regional population dynamics, which suggests potential demand in emerging overseas markets.
Our company aims to establish a sustainable water infrastructure that future generations can use with peace of mind by promoting the adoption of our Small-Scale Decentralized Water Recycling System as a standard water infrastructure that does not rely on traditional water and sewage systems.
Reason for the award:
Wota is developing a system that converts wastewater into water for daily use. In contrast to systems in which water is drawn from natural sources and then domestic wastewater is treated and discharged into rivers and the sea, the Wota system is a recycling-oriented model that considers wastewater as its standard water source, purifying it into drinkable water on the spot. The company’s proprietary technology, centered on autonomous control of water treatment, enables constant monitoring and management of water quality remotely. Even when municipal water and sewage services are shut down due to a disaster, the system lets water continue to be used as usual.
In the wake of the Noto Peninsula earthquake, Wota provided its systems along with support for their operation.
Approximately 100 showers and 200 Wosh hand-washing stations were deployed throughout the peninsula, covering 89% of the evacuation centers.
