This invention relates generally to the storage tanks for liquids and, in particular, to an underwater storage tank for water.

Water storage can be a problem, particularly in urban environments. Many cities have developed in coastal areas where there are relatively large rainfall. If the water runoff from these urban areas in the form of rain streams can capture and re-use, reduced or completely eliminated the need for construction of additional dams.

Usually the water trap with the help of a dam across a river valley. These dams are very expensive to build, and they often lead to the loss of precious agricultural land. In addition, these dams destroy all life in the river valley, and plant material captured in the artificial lake, can generate significant amounts of greenhouse gases due to decomposition of plant materials. Although in some cases it is the production of greenhouse gases can be compensated by the generation of hydropower, in General it is undesirable to build a dam.

In many geographical locations source of fresh water is usually located relatively close to the environment of the city, however, this source of fresh water may not be suitable for recovery by conventional means, that is their like a dam. For example, a typical source of fresh water is within 100 km from the zone of dense urban development.

It would be preferable to be able to capture those not currently used sources of water within or near urban areas to supply water to these urban areas.

According to the first aspect of the invention proposes a method of storing water in which:

- keep at least one flexible storage tank for submerged within the mass of sea water;

- create a ground input device, coupled with the possibility of passage of fluid from the flexible storage tank; and

- create a ground outlet, coupled with the possibility of passage of fluid from the flexible storage tank for releasing the stored water, while the discharge device is different from the inlet;

to use the valve in the intake device and the discharge device so that during loading of the tank or each storage tank inlet valve is open and the outlet valve is closed, and so that during unloading of the tank or each storage tank inlet valve is closed and the outlet valve is open; and

which at the time of loading of the water pressure head from the ground tank is used for forced induction of water in reservoirs the or each storage tank.

In the method according to the first aspect during unloading stored pressure head and/or pressure of the outer mass of sea water can be used to force the release of water from each tank or reservoir storage.

According to the second aspect of the invention proposes a method of storing water, which shall hold at least one flexible storage tank for submerged within the mass of sea water; the ground of the inlet, connected with passing of the fluid from the flexible storage tank; the creation of surface discharge device connected with the possibility of passage of fluid from the flexible storage tank for releasing the stored water, while the discharge device differs from the inlet of the device; and creating additional inlet is connected with the possibility of passage of fluid from the flexible storage tank, to provide the desired distributed water inlet.

According to a third aspect of the invention features a method that allows to carry out:

- hold at least one flexible storage tank for submerged within the mass of sea water;

- the creation of surface inlet is connected with the possibility of passage of fluid from BSG is their storage tank; and

- ground outlet, connected with passing of the fluid from the flexible storage tank for releasing the stored water, while the discharge device is different from the inlet;

in which there are at least two flexible storage tank, and at least two flexible storage tank are connected to each other with the possibility of passage of fluid through the connecting manifold.

The above aspects provide the advantage that they are not engaged valuable land for water storage. Another advantage is that the denser sea water leads to the fact that the free surface of the stored water is located above the surface of salt water, which is retained by the reservoir. This can save a significant amount of energy while removing water out of the tank.

In one embodiment, the inlet device and the discharge device is connected with the possibility of passage of fluid from the flexible storage tank through separate channels. As an alternative solution, the inlet device and the discharge device can be separated from each other or be in the common pipe.

In yet another embodiment, there are at least two flexible storage tank, these tanks are connected one with the other with the possibility of passage of fluid through the connecting manifold.

Where there is more than one water source to capture, in one embodiment, the invention may provide for the creation of more than one ground inlet to trap water, such as rivers, canals, storm water or rainwater systems.

Different water sources usually have different flow characteristics. For example, runoff of storm water usually provides a large amount of water in a relatively short period of time. The amount of water captured in this situation, can be increased by incorporating an intermediate tank connected with the possibility of passage of fluid from the land of the intake device. When there is a storm rush, then the excess flow can accumulate inside the intermediate tank, and then eventually flowing into the storage tank.

The intermediate reservoir can be formed by using one of the many ways. The tank can be made in the form of conventional concrete tank, however, such tanks can be quite conspicuous. In the alternative, the intermediate reservoir can be formed by excavation, where the security situation permits. This provides the advantage of hiding the intermediate tank.

The intermediate tank is not necessarily a must have for the n to be located in the coastal zone. It can be located, for example, among the hills or in the mountains away from the storage tank and/or away from the inlet of the device.

In some situations, the water caught her as unsuitable as drinking water. In these situations, in one embodiment, the invention may provide an additional stage of processing water from the outlet. Processing can also be performed at the inlet of the device.

According to another aspect of the invention proposes a method of licensing stored water in which the cost of a license is based on the square before catching ground inlet device. As an alternative solution, the cost may be based on the average volume of water that passes through the ground the inlet device in the time period. Other possible licensing models include models where the cost is based on the maximum capacity of the storage tank or the use of this capacity in a given period of time.

According to another aspect of the invention features a flexible reservoir for storage of water for use in submerged storage system water containing a flexible, impermeable to the fluid container, at least one tool mounting manifold, at least one collector located inside the container, at the same time, less than the least one means of mounting the reservoir is designed to hold at least one manifold in such a position that the flow of water can be maintained when emptying the storage tank.

The collector position is important when the water is sucked from the storage tank. In some conditions, the formation of pockets in the flexible walls of the storage tank, while these pockets prevent the extraction of water from the storage tank. The location of the collector can soften it.

There are several configurations of headers that can facilitate the extraction of water from the storage tank. In one embodiment, the manifold is elongated, and the input flow and the output flow of water in and out at opposite ends of the manifold. In another embodiment, the input flow and the output flow of water in and out through different headers.

Removing water from the storage tank may also be facilitated by the presence of the support, which prevents the containment walls of the flexible container of water flow when emptying the storage tank. The flexible container may also be equipped with a pressure relief valve, which prevents damage to the flexible container due to excessive pressure.

In one alternative embodiment, the container is EP further comprises a fastening mechanism for fastening a flexible reservoir for water storage configuration with one or more other flexible tanks for water storage. This mounting mechanism allows you to build storage tanks in several different configurations. These configurations include, for example, a location close to each other or stacked on top of each other. In a particular embodiment, the fastening mechanism allows you to configure and position the flexible tanks for storage of water in the cell configuration. This cell configuration minimizes the space between the tanks and thereby minimizes the space available for growth in the tanks of marine organisms. In addition, when the reservoirs are located in this configuration, the outer tanks protect the internal tanks from damage.

According to another aspect of the invention, a system of storage of water, containing a range of flexible tanks for storage of water in which the collectors to the tank or each tank are connected to each other using the connecting manifold.

In the private version of this system flexible water storage tanks are located in the cell configuration.

In other embodiments, execution of the connecting manifold is connected with the possibility of passage of fluid from the land of the intake device, or ground with a venting device, or with both of them.

Embodiments of the system may also have PR the interstitial reservoir, coupled with the possibility of passage of fluid from the land of the intake device. Optionally, embodiments of the invention can have this intermediate reservoir, formed by excavation. Embodiments of the system may also have an installation of water treatment connected with ground discharge device (or even the intake device).

When embodiments of the system are located in the mass of salt water, flexible tanks for water storage can be anchored to prevent them from moving from its set position. In addition, when the flexible water storage tanks are located in a predetermined position, the anchor can prevent the movable floating storage tanks.

According to another aspect of the invention features a storage system water containing a flexible storage tank which is submerged salt water; and ground storage tank to a location on the earth to be used and connected with the possibility of passage of fluid from the storage tank; the system is configured such that there is no limit for water flowing from the storage tank ground storage tank.

In the private embodiment, the full weight of the stored water the mass of water held in the ground tank above its the one surface of the column of salt water, is approximately 2.5% of the total mass of the stored water. This mass of water held above the surface of salt water, can be used for lifting water from tanks or other places to use as a water source. This mass of water can also be kept above the surface of salt water due to the action column of salt water on the flexible reservoir storage.

In private versions of the valves can be used, which are translated in the loading state, when the discharge pressure of the water from the ground storage tank pumps water into the storage tank. After loading valves can enter a state of discharge when stored pressure pressure pumping stored water through the auxiliary line, so that part of the stored water is pushed to the remote location.

Below is a detailed description of special embodiments of the method, the tank and the system only as an example with reference to the accompanying drawings, which depict:

In the following description uses a similar position to indicate similar elements in different variants of execution.

Figure 1-4 shows the different configurations possible embodiment of the system for water storage. Figure 1 shows a system 10 water storage, with five flexible storage tanks in the form of containers 12 that are held in the thickness of the salt water 14 and connected with the possibility of passage of fluid from terrestrial inlet device 16 located remote from the sea territory 17, and ground the exhaust device 18 located near sea water 14.

When using water, such as rivers, storm water or rain water passes through the inlet device 16 and into the container 12. Water can be removed from container 12 by extracting water from the ground outlet 18.

In this embodiment also dug in the ground tank 26 for storing water as the tick tank. In alternative embodiments perform this tank may be in the form of a conventional tank above ground level, such as concrete or steel tank. Tank 26 serves as a battery to ensure the intake of excess water flow to the intermediate storage to the time required for the passage of water through the ground the input device 16 and the container 12. This ability of inhibition of water increases the amount of water captured by the system, and can reduce losses overflow.

Water can be extracted from the exhaust device 18 for typical use of the saved water. For example, water can be carried out in the installation of water treatment (not shown) for subsequent distribution as a domestic drinking water. Other applications include the use of treated or raw water for industrial and agricultural purposes (e.g. irrigation).

The input device 16 and outlet 18 is connected to the container 12 through separate channels 12. However, the input device 16 and outlet 18 may be in the General channel. The channels 20 may be embedded in the ground, and then be in the form of pipes on the bottom of the sea to the containers 12.

The containers 12 are connected to each other by the connecting manifold 22, which takes water from the reservoir 24 extracting located within each of the to the of nteynery 12. Connecting the collector 22 passes water in the channels 20 of them and distributes water between containers 12.

In the embodiment shown in figure 1, there are two collector 24 of the extract in each container 12. The intake manifold 28 receives water from the inlet 16 and the outlet manifold 30 extracts the water from the container. In other versions of the invention, only the collector can act both as intake manifold, and exhaust manifold.

In an alternative embodiment, the two connecting manifold located on opposite ends of the container. These connecting collectors connected to opposite ends of the combination of the intake/exhaust manifold. When using water from the inlet passes into the container through the first reservoir, and the water passes from the container into the exhaust device through another header.

On figa-6C illustrate several configurations of the container 12. Shows how different configurations of the shape of the container 12, and the configuration of the reservoir 24 to retrieve.

On figa(i) and 6A(ii) shows an embodiment of a system in the empty state and in a fully filled condition, respectively, while the collectors 24 extracting located inside the container 12. Vertical bearing 24 in the steps of the rigid base 36 of the container 12 and you are using supports a flexible membrane 38 of the container 12, when the container 12 is in the empty state.

Each of the manifolds 24 are attached to the mounting mechanism 32, which is integrated in the support 34. The location of the reservoir on the support 34 by means of the fastening mechanism 32 contributes to the conservation of water flow by preventing closing of the flexible membrane 38 of the inlet and outlet manifolds 24 extraction. The container 12 is also equipped with a safety valve 44.

A relief valve 44 prevents damage to the container 12 when it occurs inside the container 12 gauge pressure of water.

An alternative implementation of the system in an empty and completely filled condition shown In figure 6(i) and 6(ii). In this embodiment, the four collector 24 extract (two inlet and two exhaust manifold) swim at the far end 40 of the vertical support element 34, which protrudes from the rigid base 36 of the container 12. In this embodiment, when the approximation of the container 12 to the empty state remains a void in the area below the far end 40 of the vertical support element 34, where the flexible membrane 38 forms a veil over the pillar and reservoir 24 extraction. In this embodiment, the four collector 24 extraction are afloat and slide on the support 34.

Another alternative embodiment of a system like the empty and the full state is shown in figs(i) and 6C(ii). In this embodiment, having a hexagonal shape, the containers 12 are connected to each other in the stacked cell configuration. This cell arrangement has the advantage that when approaching the container 12 to an empty state of the reservoir 24 extract from located on the same vertical line of containers 12 are superimposed on each other to help prevent the closing of the flexible membrane 38 of the inputs and outputs of the collectors 24 retrieval.

To facilitate locking of the containers 12 in a defined configuration provided by the locking elements 45, as shown in figs(iii), on the edges of the containers 12. Alternating male and female locking elements are located on opposite sides of the container 12 to provide locking configuration sequence similar containers.

In alternative versions of the oval or rectangular containers can be stacked in a similar configuration with dense packing. By locating containers in a stacked configuration minimizes space available for marine organisms, between containers. Stacked configuration also provides the advantage that the outer container protects the inner container from damage. Therefore, even in case of an attack sea creatures on the system or what other damage for example, due to the storm, the outer containers provide a protective barrier for the inner container.

To prevent contamination of the stored water in the intact container due to rupture of the container system is equipped with a monitor 46 salinity. When detected elevated levels of salt in the container 12, actuates the valve to isolate the collector 24 of the extraction of contaminated container 12 from the connection of the collector 22.

There are several possible ways to fix the containers 12 at the bottom of the mass of salt water. In one embodiment, the at the bottom of the sea drilled nylon anchors, and the containers 12 are attached to these anchors. In an alternative embodiment, in each container, you can use concrete goods placed in the pockets, which act as ballast. The method of attachment of the containers 12 at the bottom of the column of sea water also depends on the location. For example, if the containers should be placed on the bottom of the lake, the use of concrete goods may be sufficient for securing containers. However, if you want to place the containers into the sea, the more likely the use of more sustainable fastening mechanism, such as a nylon anchors.

Figure 2-4 shows alternative embodiments of the scuba tank for water.

In figure 2 the system is implemented in the coastal configuration, the intermediate tank 26 for water is located near the river 48. The feed channel 50 diverts water from the river 48 in the intermediate tank 26. The intermediate tank 26 and ground discharge device 18 is connected to the container 12 through channels 20. These channels are located on the bottom of the river. The exhaust device 18 is connected to the water treatment plant (not shown). When using an excessive flow of water from the river can be collected in the tank 26 until the water has sufficient time to pass down the channel 20 in the container 12 for storage.

Figure 3 shows a system remote from the sea configuration. In this embodiment, when filling the channels 20 water volume of water displaced from the containers 12 a dense sea water, keeps the channels in the filled condition and reduces the cost of pumping required to extract water from the container 12. In such a system can use a single channel for both intake and release of water from the container 12.

Figure 4 shows the system with the primary inlet device 16, the remote for a few hundred kilometers from the container 12. The intermediate tank 26 is located near a remote river, with the feed channel 50 diverts water in the intermediate tank 26. In this embodiment, is also provided secondary inlet ustroystvo'. As the primary input device 16, and a secondary inlet device 16' are connected to the common connection of the collector 22 for connection of the container 12 with the inlet devices.

When water must be transported long distances, you can use the pump to increase the pressure in the pressure channel 20 which conducts the water into the container 12.

Figure 5 shows an example of calculation of reservoir capacity. After determining the storage requirements in this place you can choose the system components to ensure the specified storage conditions. On figa shows the design requirements for a system capacity of 10 million litres.

On FIGU shows the calculation of the area of capture and the amount of recovery for the area of capture. In this example, the calculated surface area of the roof of the stadium to capture 10 million litres of water per year for storage.

When licensing these systems license cost can be defined using various parameters. For example, the cost of a license may be based on the size of the capture or storage size. The cost may be based on an average annual volume of trapping water within a specified period of time or area capture. As an alternative solution, the cost of a license may be based on the maximum storage capacity of water or IP is the use of this capacity. The cost can be calculated by determining the volume of the containment, and then multiplying this value with unit cost. Then this cost may be paid annually by the licensee.

Although the description of the method, the tank and the system was described with reference to private options run for specialists in the art it is clear that they can be implemented in many other species. For example, flexible storage tanks can hold pylons. In addition, in connection with the system you can use other stages of conventional water treatment. For example, you can perform some pre-processing of water before entering the storage tanks.
