Case Study of the benefitial use of rain water in connection with water quality at the Rainwater Harvesting Experimental House to store heavy rainwater

Abstract

 This paper indicates an advantage of the beneficial use of heavy storm rainwater at Rainwater Harvesting Experimental House. Rainwater harvesting is the use of rainfall on the roofs and storage runoff storm water under the storage tanks for urban flood control. In the simulation results, the significance of the storage of storm rainwater reservation is proved by many researchers. There is no private house which was built for the purpose of controlling urban flood damage, and the dispersed storage tanks effect is not yet demonstrated.
 We carried out the monitoring at the rainwater harvesting experiment house which was built in April, 2012 for the purpose of restraining an urban flood in this research. This study examines the possibility of the rainwater use and flood damage suppression effect by the construction of the rainwater harvesting house.
