In this case, rainwater and bathtub water having favorable water quality and the waste water from the washing machine and the basin containing dirty waste are conducted to the water reservoir 9 through separate piping 3, 4 and the piping is controlled to open/close to preferably conduct the rainwater and the bathtub water into the water reservoir 9.
