A prototype SRT system has been installed in a gravel-filled 110 tons underground tank in the Oginoura Garden Suburb, which is a maisonette-type housing complex, where its functions are now being tested. Initial results indicate that measuring rainfall using the gravel-filled underground tank is not suitable due to spikes in the water level after a heavy rainfall event has occurred. So, we decide to install a void type of 5.6 tons rainwater tank to the personal house for Moriyama. It will be installed a sensors at the first quarter of 2016.
For pre-discharge of rainwater before heavy rainfall, diagnosis for heavy rainfall by using SOM is installed. This diagnosis is installed on “Internet Cloud” and possible to send a order to SRTs with pumps. The accuracy of diagnosis for heavy rainfall is investigated, but it is only for Aug. 2014, it should be more investigation.
