Japan’s Taisei Corp. Launches ‘Zero Water’ Building; System Only Uses Rainwater, Recycled Water
Taisei Corp. has opened its Zero Water Building in Tamura, Fukushima Prefecture. The building utilizes a system that uses rainwater and recycled wastewater so that even during a supply cutoff, water can keep flowing.
Taisei Corp., a Japanese construction company, has unveiled its innovative Zero Water Building in Tamura, Fukushima Prefecture. This groundbreaking structure employs a system that relies solely on rainwater and recycled wastewater, ensuring a consistent water supply even during potential cuts.
The 30-ton water tank, installed within the 585 square meter building, is a key component of this sustainable design. The wooden facility serves as the administrative block for Taisei's next-generation technology demonstration center, T-Field/Tamura. The system relies on artificial intelligence to monitor and adjust water usage based on factors such as weather patterns and existing consumption levels.
Beyond collecting and purifying rainwater for everyday use, the system also treats domestic wastewater, repurposing it for toilet flushing. This dual approach ensures a continuous water supply even in the face of natural disasters, including earthquakes rated up to 7 on Japan's seismic intensity scale.
While standard water supply systems are in place as emergency backups, they will not be utilized under regular operational conditions. Taisei envisions a nationwide rollout of this system, not only for private buildings but also for public facilities, potentially incorporating the water recycling technology as well.
