"Profitable disaster preparedness": infrastructure that earns in normal times and supports the community in a disaster

Message for the Open Pitch

“Not "preparing for a disaster", but "everyday life that is itself the preparation". With technology that circulates water, INNFRA builds new infrastructure useful both in normal times and in emergencies. From Makinohara to the whole country — join us in creating a future where the entire town is disaster infrastructure!”

Original: 「防災のために備える」のではなく、「いつもの暮らしが、そのまま備えになる」。 INNFRAは、水を循環させる技術で、平時にも災害時にも役立つ新しいインフラをつくります。牧之原から、全国へ。「まち全体が防災インフラ」になる未来を一緒につくってください!

Proposal

Proposal overview

Against the difficulty of maintaining infrastructure amid population decline and increasingly severe natural disasters, we offer "profitable disaster preparedness" built on INNFRA Base, a movable water-recycling container. It treats and circulates rainwater and household greywater, supplying the water needed for showers, laundry and more even where there is no mains water or sewerage. In normal times it earns revenue as a coin laundry, coin shower, lodging or commercial facility; in a disaster it functions as water infrastructure for evacuation centres. Working not only with local government but with a wide range of regional businesses in finance, construction, retail, lodging and primary industry, we distribute sustainable disaster-response bases across the region as private-sector operations. Everyday economic activity itself becomes preparation, and local companies and residents raise the area's disaster resilience simply by using these facilities day to day — realising a society in which the entire town is disaster infrastructure.

Original: 人口減少によるインフラ維持の困難化と、激甚化する自然災害に対し、可動型水循環コンテナ「INNFRA Base」を活用した「稼ぐ防災」を展開します。雨水や生活雑排水を処理・循環し、上下水道がない場所でもシャワーや洗濯等に必要な生活用水を供給。平時はコインランドリーやコインシャワー、宿泊・商業施設等として活用して収益を生み、災害時には避難所等の生活用水インフラとして機能します。自治体に加え、金融、建設、小売、宿泊、一次産業など地域の多様な事業者と連携し、民間事業として持続可能な防災拠点を地域に分散配置。平時の経済活動そのものが災害への備えとなり、地域の企業や住民が日常的に利用しながら災害対応力を高める、「まち全体が防災インフラ」となる社会を実現します。
