The fresh water is injected from the land and the stored water is discharged to the land. As described above, since the water storage location is underwater, there are fewer restrictions on location than in the case of land dams and tanks. Also,
The water pressure of the fresh water stored in the water storage bag is canceled by the external water having a specific gravity almost equal to that of the fresh water, so that the water can be stored even if the strength of the membrane material is relatively small. Further, even if the water storage bag is damaged, the environmental impact is small, so that the safety factor in terms of structural strength can be made small. In addition, the number of days required for construction is significantly less than for land dams and tanks.

As shown in (3), a water intake weir 74 is provided near the mouth of the river 73 to guide the river water to the water reservoir 71. In addition, a water storage bag 13 is provided in the sea, and fresh water is stored in the water storage bag 13 by connecting it to the intake reservoir 71 via a communication pipe 72 to keep the water level of the intake reservoir 71 higher than the sea level to some extent.

As the injection amount of river water increases, the water storage bag 13 is deformed as shown in FIG. 2 to store river water (fresh water) inside. When there is a demand for fresh water, the pump 15
The stored water is pumped out from the water storage bag 13 and used as appropriate. Normally, the water levels of the intake reservoir 71 and the storage bag 13 are balanced at the water level in the storage bag 13 higher than the sea level due to the difference in specific gravity between fresh water and seawater. When the fresh water is pumped up, the water storage bag 13 is compressed by the water pressure of the seawater and becomes small, and the river water automatically returns from the water storage bag 13 through the communication pipe 72. By setting the location of the water storage device in the sea as described above, there are fewer restrictions on location than in the case of land dams and tanks. Further, structurally, the water pressure in the water storage bag 13 due to fresh water is canceled by seawater having a specific gravity almost equal to that of fresh water, and water can be stored by a membrane material having a relatively small strength. In addition, by storing fresh water in seawater, even if the membrane material of the water storage device should be damaged, there is little impact on the environment. Therefore, the safety factor of the structure can be made small and economical manufacturing becomes possible. .

As shown in, fresh water is sent by the sending pump 92 into the water storage bag 41 provided in the sea.
A river water intake device (not shown) is provided at the base end of the valve 94a, and fresh water is sent from this intake device into the water bag 41 by the sending pump 92 through the valve 93a. Further, the fresh water produced at the seawater desalination plant 95, which is installed on land or on a barge and patrolls at appropriate times, can also be stored by opening the valve 94b. When fresh water is needed, fresh water is dispensed by closing valve 93a and opening valve 93b.
It is sent to the required destination by 5. The water storage bag 41 is formed in a bag shape with a flexible membrane material such as a water-impermeable cloth or vinyl, and the ballast material 42 for adjusting the buoyancy due to the difference in specific gravity between seawater and fresh water is put in the bottom of the water storage bag 41 from the beginning. It is submerged and fixed on the sea floor. By forming the membrane material in multiple layers as necessary, it is possible to prevent seawater from being mixed into the fresh water stored therein even if a part of the water storage bag 41 is damaged. Further, by applying a slight pressure to this multi-layered portion with fresh water of another system, the effect of avoiding contamination can be further enhanced.

よって給水制限などの事態を改善することができる。Conventionally, dams and tanks have been used as water storage devices for water supply facilities and the like, but in the case of dams, new construction has become difficult in recent years due to difficulty in location near large cities. In addition, the dam also has the purpose of preventing flooding outside the reservoir, and before a period of heavy rainfall, a portion of the reservoir may be discharged to avoid a flood, and in some cases a portion of the reservoir may be released. May be wasted. In addition, it takes a long time from the decision of the site to the construction and completion of the dam, which requires a lot of money. Further, in the case of a tank, there is a drawback that it is difficult to increase the capacity. Further, the tank needs to have sufficient strength against water pressure due to water storage, and structurally strong one is required from the viewpoint of safety. However, in the water storage device according to each of the above-mentioned embodiments, the place to store water is set in the sea. As a result, although there are problems with fishing rights and marine traffic, it is easier to install compared to the case where a dam or tank is newly built on land. In addition, the effective use of water resources can be achieved by collecting river water that has been conventionally discharged for flood control and storing it in these water storage devices. In addition, it is considered that the construction period should be two to three years, and the number of days spent for construction is significantly shorter than that of dams, etc., and it is easy to add more as needed. Further, by balancing the water pressure of the stored water with the water pressure of the seawater, the load applied to the water storage bags 13 and 41 is reduced, the structure is simplified, and at the same time the capacity can be increased. Also, by installing it in the sea, there are fewer restrictions on location than when constructing a dam or tank on land. Further, only the differential pressure between the pressure of the seawater and the pressure of the stored water is applied to the water storage bags 13 and 41, and the strength of the water storage bags 13 and 41 can be small. In addition, even if there is an accident such as damage to the water storage bags 13 and 41, the impact on the environment is extremely small,
The safety factor for strength can be reduced. Especially in western Japan, there is a high possibility of drought, but many places are suitable for installing such water storage devices, and by installing these water storage devices, situations such as water supply restrictions can be ameliorated.

It is economical because the rate can be kept small and the number of days spent for construction is much less.
