Installed mobile sand filtration device in the disaster area by Typhoon Yolanda in the Republic of the Philippines. ~Dispatched the emergency assistant team for supplying drinking water, “NIHON GENRYO WATER RESCUE”~

NIHON GENRYO dispatched the emergency assistant team for supplying drinking water to the serious disaster area by Typhoon Yolanda in the Republic of the Philippines to install “Mobile Siphon Tank”, which is the mobile sand filtration device, through “Pilot Survey for Disseminating Small and Medium Enterprises Technologies”, collaborating with JICA (Japan International Cooperation Agency). Our emergency assistant team installed and provided the high quality drinking water for just 3 days after we arrived at Daanbantayan, which is located in the north of Cebu Island in the Philippines, in December. 20th, 2013. Also, the filtered water was supplied by water trucks to deliver the “safe water” to the neighboring districts. The raw water got muddy, whose turbidity was from 20NTU to 30NTU, because the water source was used for bathing area for cows and washing area for the local people; however, our team realized 0.07NTU, which is the drinkable level, as the filtered water’s turbidity through “Mobile Siphon Tank”.
