BEST MODE FOR CARRYING OUT THE INVENTION In this example, the rainwater tank is a water tank, a water tank and a water tank (an example).
In addition, a filter (specific gravity separator) is installed in front of the water tank to purify rainwater, and a tank for storing suspended matter such as trash and foreign matter, and a sediment for head and foreign matter, for water discharge. Prevent entry into tanks. Further, a makeup water tank is provided between the water storage tank and the water discharge tank, for example, a water tank, a water storage tank and a water discharge tank (in one example, when collectively referred to, a rainwater tank)
If any of the water is insufficient or runs out, it is filled with water from makeup water. This make-up water is, in principle, clean water, but can be other water. Therefore, effective use and / or supplementation of rainwater and clean water is achieved, and the object of the present invention is achieved. Water enters through the rainwater inlet pipe (water inlet pipe) through this filter, and secondarily removes dents, hedrons, foreign matters, foreign substances, etc. in the water inlet tank by the principle of specific gravity, for example, enters the water outlet tank. Get rid of. As shown in this example, water tanks for water input and water output can be used as basic units to store water whenever necessary.
Or, by adding tanks for makeup water, etc., adjustment of water storage volume,
There is a real benefit of being able to secure a rainwater utilization device of large and small dimensions corresponding to the installation space of a space or the like, or a form useful for effective use of clean water / rainwater and reduction of the amount of clean water used.

Explaining one example of the flow of water, rainwater is guided to a filter through a pipe, and the filter separates foreign matters such as dents, heads, and foreign substances. The clear water separated by this filter is introduced into the water tank via piping (water pipe / water pipe), and then reaches the water tank via the water storage tank and makeup water tank in the same manner. It The water in the water tank is drained from the water outlet and used, for example, for watering (using a pump), car washing, watering for plants / plants, other watering, or household water.

An example will be described in which a makeup water tank is additionally provided between the water entry tank and the water exit tank. For example, when the water in the makeup water tank is filled with a predetermined amount, the water stopping means (which may be remotely operated) is closed, and no water is introduced from the makeup water pipe. However, when the predetermined amount of water in the makeup water tank is not filled, the water stop means is opened and water is introduced from the makeup water pipe. Then, if necessary, the entire water discharge tank is filled with a predetermined amount of water. If you add this tank for makeup water, it will be useful because it can be used all the time. The water stop means is a float valve.
(Valve: water stop etc.) mechanism, float switch valve mechanism, level sensor valve mechanism, sensor valve mechanism such as optical sensor, etc. are adopted, but not limited thereto.

It is to be noted that a filter, a rainwater tank, etc., dents, heads, etc. are removed by using a cleaning port, a discharge pipe, an opening, or another extracting means. When it is necessary to increase the amount of water storage, for example, one or several water storage tanks are added between the water input tank and the water output tank as needed. Further, the present invention is introduced from below by using water inlet pipes (also used for connection) provided at lower portions between the rainwater tank and the makeup water tank. Further, it is desirable to make uniform the amount of water stored in the rainwater tank and / or the makeup water tank by using this water inlet pipe. When a large amount of rainwater is used, open means such as manual or automatic, an overflow mechanism, or a bypass mechanism is used.
