There are 3 Hydroelectric power plants, Kogashira, Koyamada, and Takafu plants. Natural aquifer filtration process Power plants It is then treated with chemicals and filtered again and finally stored in water tanks. The water from the river or from underground is filtered to remove sand and large debris. We use two sources of clean water in Kagoshima. The water goes through the shirasu plateau and is used to supply tap water. The rain that falls on the Shirasu base quickly penetrates into the ground. Desalination process Kagoshima’s Shirasu PlateauĦ0% of Kagoshima sits on a shirasu plateau. If we provide a family of four with desalinated water for one day, it costs the same amount of energy as using an air conditioner for one hour. Thanks to this process, this water doesn’t contain as many minerals as Kagoshima water, so it is more pure.The cost of this process is very economical. Remove the small particles with pressure.Remove the large debris from seawater using a filter.There are some differences in the way tap water is produced between Kagoshima and Perth. We can drink clean water anywhere and at a low cost. In Kagoshima, the rate of water supply penetration is 100%. embankments and breakwaters Water Quality These are used to prevent flood disasters and to store water. There are embankments and breakwaters everywhere. Not only in Kagoshima but also in the Kyushu area, we have especially good measures against flood disasters. For example, power outage, floods, and the collapse of roads and houses. Very rarely, it causes a horrible disaster. Typhoons come to Kagoshima 4 or 5 times every year on average and peak from July to October. Kagoshima has a lot of rain and typhoons. (Perth has 807 mm/year.) Annual rainfall Kagoshima 2265 mm/year Perth 807 mm/year Protection from weather disasters The annual average amount of rain in Kagoshima is 2265 mm. We don’t worry about depletion and there is no rule about sprinklers or water use. In Kagoshima, it rains a lot more than in Perth, so we have a lot of water resources. The Rain Protection from Weather Disasters Water Quality Power Plants The Rain rainy day in Kagoshima This page describes the water and infrastructure of Kagoshima city. There are some differences between Perth and Kagoshima. Infrastructure is one of the most important things to support our life, especially regarding water.
