Support for small and medium-sized enterprises in downtown areas: Installation of two water purification systems providing 1,000 liters of drinking water per hour to the disaster-stricken areas of the Noto Peninsula earthquake.
Top Water Systems Co., Ltd. has installed two water purification devices at a pharmacy in Wajima City, Ishikawa Prefecture, on January 17 and 18, to provide drinking water, water for daily use, and toilet water to the victims of the Noto Peninsula earthquake in Reiwa Year 6. Based on our experience in securing drinking water for decontamination workers in Minamisoma during the Great East Japan Earthquake in 2011 and the introduction of soft water machines to a public bath in Yasunuma Town during the Kumamoto earthquake in 2016, we have been promoting the series of disaster water purification devices called "TOP Rescue RO." This device is a large-capacity model equipped with a gasoline-powered generator that can produce 1,000 liters of water per hour. It can be continuously operated even in the unpredictable weather of the Noto region, making a significant contribution to securing water in disaster-stricken areas.
