AQUA in PIT
▌For Securing a Lifeline of Water in the Case of an Earthquake AQUA in PIT – Water Circulating Storage Tank
AQUA in PIT is a water storage tank that is directly connected with water supply pipes so that water can circulate constantly. Unlike a conventional water tank that only stores water, AQUA in PIT works as a part of water supply pipes, and can supply water for drinking and fi refi ghting in the case of a disaster to save people’s lives.
■ Supplying Fresh Water
AQUA in PIT series has unique structure to achieve eff ective water fl ow. AP-03, AP5 and AP20 have a tapered pipe and a disc. AP40 and AP100 are equipped with a divider plate inside. These devices help water circulation effi ciently.
In our experiment using AP-03, AP5 and AP20, 3.6 times as much as tank capacity could replace 99% of water inside. As for AP40 and AP100, the water was replaced by supplying three times the volume of tank capacity water. You can select a tank from our product line based on the amount of water needed at the site.
■ Reliable Safety
Because the AQUA in PIT tank is buried underground, it is very safe in the case of a disaster. Moreover, it has a high pressure resistance; AP-03 and AP5 have passed the pressure test at 1.75MPa, and AP20, AP40 and AP100 withstood the test at 1.23MPa according to the certifying parties.
