That is, the rainwater from the roofs HK is collected by the collecting gutters EF and once lowered to the ground or the ground, and then to the middle-position rainwater storage tank A having a level difference according to the U-shaped pipe principle. It is configured to be raised and stored. Rainwater from the roof G is collected in the drainage gutter N,
After pouring water into the high-position rainwater storage tank T1, the high-position rainwater storage tank T2 is also filled with the U-tube principle.

The rainwater overflowing from the high-position rainwater storage tanks T1 and T2 can be supplied to the middle-position rainwater storage tank A. The rainwater overflowing from the middle-position rainwater storage tank A can be supplied to a buried low-level rainwater storage tank B. When the low-level rainwater storage tank B is filled, the low-level rainwater storage tank B flows down from the overflow pipe Y provided in the low-level rainwater storage tank B to the reservoir L. Further, the bottom of the reservoir L and the bottom of the low-level rainwater storage tank B are communicated with each other by an on-off valve and a communication pipe, and can be supplied in addition to the inflow from the overflow pipe Y. The reservoir L can be supplied even at a low water level. Therefore,
Even in summer when the evaporation from the reservoir L is severe, the rainwater can be supplied from the low-level rainwater storage tank B to the reservoir L.

The rainwater overflowing in the reservoir L is:
Water is distributed to the rainwater penetrating pipe X, and is penetrated into the ground in the site from the rainwater penetrating pipe X.
The reservoir L is a pond in which freshwater fish, aquatic animals and aquatic plants can inhabit, and a fountain pump P2 is disposed inside the reservoir L so that the fountain is constantly blown up. The low-level rainwater storage tank B is a tank constructed in a semi-underground state on the site of a house, and is provided with a high-level rainwater storage tank T1.
It is configured to store overflowing rainwater in T2 or in the middle-position rainwater storage tank A.

In order to avoid such a situation, a fountain is generated by the fountain pump P2, aeration and purification are performed, oxygen is absorbed in water to make it aerobic, and generation of ammonia gas and the like is suppressed.

Further, the inside of the reservoir L gradually becomes eutrophic,
The overgrowth of aquatic plants creates an anaerobic condition,
In the reservoir L, aquatic animals such as fish, frogs, goats, and water sparrows are bred, and the eutrophic substances absorbed by the phytoplankton and the zooplankton are further absorbed by the aquatic animal. Leaving out of reservoir L avoids enhancing eutrophication. It is also a way to avoid eutrophication when fish are taken out by a heron, and yago becomes a dragonfly and flies, and a ladle goes out as a frog. The purpose of the deterrence will be achieved. In addition, eutrophic elements such as nitrogen and phosphorus can be removed by thinning and feeding aquatic plants such as water hyacinth which have proliferated due to eutrophication to a composting device W described later. That is, it is avoided.
