In Japan, people generally believe that turning on the tap will provide safe water. But Japan is an outlier, even worldwide. About 25% of the global population lives without access to water infrastructure. WOTA is a Japanese startup company taking on the challenge of providing structural solutions to water issues.

Instead of a large-scale civil engineering model, WOTA proposes a manufacturing industry-based model using its proprietary automated control technology for water treatment. This small-scale and efficient approach allows for constant control and monitoring of water safety during operation.

Global Water Issues

In 2015, the United Nations adopted the Sustainable Development Goals (SDGs) at its General Assembly. "Clean water and sanitation for all" is one of the goals to be achieved by 2030.

Demand for water is rising with the increasing global population. Simultaneously, developments in industry have improved living standards and led to an upward trend in water usage. Industrial and domestic wastewater contributes to the contamination of rivers, seas, and groundwater. Urbanization-driven development also impacts and disrupts natural water sources. 

The Tokyo Metropolitan Government estimates the individual's daily water usage in households to be approximately 214 liters.

About 97% of the Earth's water is saltwater. Water that can be used for drinking constitutes less than 0.01% of the total water on our planet. 

Climate change brought on by global warming drastically alters precipitation patterns, creating new regions grappling with water shortages. The progression of desertification due to drought is a serious concern. By 2030, more than 40% of the world's population will be at risk of water scarcity. Meanwhile, disputes over the distribution and ownership rights of water persist worldwide.
