Multiple water pipe failures (October 8, 2021)

Yesterday, October 7th, an earthquake with a maximum intensity of 5+ struck the Kanto region. As of 12:00 PM on October 8th, according to information on the internet, there are 26 locations in the Tokyo metropolitan area with water leaks due to damaged water pipes, and damage to the Yoro River water pipe bridge in Ichihara City, Chiba Prefecture. There have been no reports of water outages from this earthquake, but if an even stronger earthquake were to strike, the area of damage could become more widespread, and water outages could occur.

The recent collapse of an aqueduct in Wakayama City highlighted the aging of the aqueduct itself, and reports indicate that there are approximately 5,000 similar aqueducts nationwide. While maintenance and replacement of the aqueducts themselves are necessary, it is equally important to establish systems to ensure continued water supply even in the event of damage.

As we reported in our news article on October 5th, "Regarding the Early Restoration of Water Pipes Using Large-Diameter Hoses (October 5, 2021)," we are proposing the "Super Aqua Duct Hose" (maximum 300mmΦ) as a measure to quickly restore water pipes. It can be laid in a very short time, enabling early restoration.

Over the past few days, we have seen, in an unexpected way, the weaknesses of Japan's social infrastructure become apparent. We hope that our proposal for large-diameter hoses will help maintain the functionality of the water supply, a vital social infrastructure, during disasters, and contribute to the safety and security of those affected.
