While electricity, water, communications, and various other lifelines support our lifestyles, they also have constraints. How would our lives change if this infrastructure became portable? People might have more freedom to choose where they live and in areas lacking the financial resources to build infrastructure grids, it might become possible to create living environments with just a small amount of investment. WOTA is an innovative initiative aimed at introducing a recycling system to the water sector, which has been lagging behind in the areas of liberalization and decentralization. Centered on a specially developed water quality sensor and AI technology, the filtering system is due to be further refined and will likely contribute to the emergence of products and services in the future. We hope that the creators of this system will look beyond its use in response to disasters to cultivate new infrastructure that will transform the relationship between people, water, and the environment.
