Description

Description Title of the invention: Water storage building

[0001] The present invention relates to the field of water storage and more particularly to a building for water storage, treatment and reuse.

[0002] Water scarcity affects different geographic areas, different periods, and poses different human needs. Access to water, especially drinking water, is a growing problem, especially in this era of climate change and global warming.

[0003] In addition to the vital need and comfort of using water, which we experience in developed countries, there is the notion of waste, which creates gaps in access to water and a great disparity at the global level. Human activities such as domestic supply and consumption, hygiene, health, use for agriculture, industry, transport, cleaning of urban areas as well as energy production are water consumers and generally to the detriment of nature's needs.

[0004] In addition, water needs and its evacuation create problems of transport and routing of water, generally via pipelines. However, these pipelines have a significant environmental footprint and are also a source of leakage and waste of water resources, particularly in isolated or difficult-to-access geographical areas.

[0005] One of the aims of the present invention is therefore to remedy the drawbacks of the prior art and to propose a water storage building with a limited ecological footprint, in particular for the water resource, its local environment, autonomous and capable of meeting needs.

[0006] The present invention therefore relates to a water storage building comprising on the same floor: - a first water tank called a buffer, - a second water tank with a volume greater than the first water tank, - a technical room comprising at least one device for treating and / or filtering the water from the first tank, the treated water being conveyed and stored in the second water tank, - at least one water-consuming device for using treated water from the second tank.

[0007] According to one aspect of the invention, the water storage building comprises a water pumping device.

[0008] According to another aspect of the invention, the water pumping device is remote from the building.

[0009] According to another aspect of the invention, the second water tank is arranged in a central position, the first water tank, the technical room and the at least one water consuming device being arranged on the sides of the second tank.

[0010] According to another aspect of the invention, the second water tank has a quadrilateral shape, the first water tank and the technical room being arranged on the same side of the second water tank.

[0011] According to another aspect of the invention, the water storage building comprises a roof configured to collect rainwater and transfer it to the first water tank.

[0012] According to another aspect of the invention, the water storage building comprises a roof comprising photovoltaic panels.

[0013] According to another aspect of the invention, the water storage building comprises a roof comprising an overhang, the at least one water-consuming device being arranged under this overhang.

[0014] According to another aspect of the invention, the at least one water-consuming device comprises at least one shower and / or at least one toilet and / or at least one mist sprayer and / or at least one water outlet and / or a drinking trough.

[0015] According to another aspect of the invention, the structure of the water storage building as well as the first and second tanks are made of concrete.

[0025] Figure 1 shows a water storage building 1 according to the invention. This water storage building 1 comprises, on the same floor: - a first water tank 10 called buffer, - a second water tank 20 with a volume greater than the first water tank 10, - a technical room 30 comprising at least one device 31 for treating and / or filtering the water from the first tank 10, the treated water being conveyed and stored in the second water tank 20, and - at least one water-consuming device 40 for using the treated water from the second tank 20.

[0026] Initially, the recovered water is stored in the first water tank 10 in which it can in particular undergo a first settling step. The water is then treated and / or filtered by the at least one treatment and / or filtration device 31 and then stored in the second water tank 20.

[0027] The second water tank is then connected to the at least one water consuming device 40, in particular for sanitary and recreational use in order to allow the reuse of the stored water. The water storage building 1 may comprise a pump, for example in the technical room 30 in order to distribute the water from the second water tank 20 to the at least one water consuming device 40 with a determined pressure and flow rate.

[0028] Such a water storage building 1 has several important aspects. In particular, it allows for the storage of water, especially rainwater, to regulate it and limit its speed. This ensures the infiltration of fresh water into the environment. Such a water storage building 1 also allows for human uses, for example, watering and use by firefighters. All of this is achieved, in particular, with filtered and treated water.

[0029] In addition, such a water storage building 1 allows the recovered water to be returned to the surrounding natural environment, to decontaminate it and to allow slow and prolonged deep infiltration of the stored water. The quantity of stored and infiltrated water can in particular be sufficient to nourish a biodiversity of fauna and flora in the first layers of the soil, thus recreating zones of biological density and resting areas for living organisms. By multiplying these "bridges" or "islands" of biodiversity, it is possible to allow the soil to rebalance itself and overcome periods of water stress, by providing "emergency areas".

[0030] This infiltration is also significant in depth, particularly in areas of high population density, heavily concreted, in which the soils are made highly impermeable. This results in a problem of flow and distribution of runoff water. Storing water in such water storage buildings 1 thus makes it possible to limit the risks of flooding in these areas. One or several water storage buildings 1 in fact make it possible to limit significant and sudden arrivals of water, with too much speed, in specific and known locations, particularly at risk. Such a storage building water storage building 1 then acts as a sort of buffer to control the flow of water, particularly runoff water. In addition, the treatment and / or filtration of its water within a water storage building 1 also helps to limit the risks of polluted effluent being discharged into natural environments.

[0031] The fact that the water storage building 1 is built on a single floor, particularly on the ground floor, allows for easy manufacturing and installation. This is particularly important for installation in a natural environment and helps limit the ecological impact of the water storage building 1.

[0032] For this purpose, the structure of the water storage building 1 as well as the first 10 and second 20 tanks can be made of concrete.

[0033] The water storage building 1 may in particular be made from prefabricated elements such as panels, slabs, roof elements 60, for example made of concrete, and assembled in situ, above ground or buried.

[0034] The water storage building 1 may in particular comprise a water pumping device 50, collecting in particular pumped water. In order to allow optimal efficiency of this pumping device 50, the latter may be offset from the building. It is thus possible to arrange the water storage building 1 and its pumping device 50 in different and appropriate locations.

[0035] As shown in Figure 1, the structure of the water storage building 1 can be centered around the second water tank 2. The second water tank 20 is thus arranged in a central position. The first water tank 10, the technical room 30 and the at least one water consuming device 40 are arranged on the sides of the second tank 20.

[0036] Such a simple structure allows in particular a simple and standard manufacture of the water storage building 1.

[0037] Still according to the example of Figure 1, the second water tank 20 can have a quadrilateral shape. The first water tank 10 and the technical room 30 can thus advantageously be arranged on the same side of the second water tank 20. Sanitary devices 40 can thus be arranged on the three remaining sides of the second water tank 20.

[0038] Other shapes of the second water tank 20 may also be conceivable, for example a cylindrical shape.

[0039] As shown in Figure 2, the water storage building 1 may comprise a roof 60. This roof 60 may in particular be configured to collect rainwater and transfer it into the first water tank 10.

[0040] The roof 60 of the water storage building 1 may also include photovoltaic panels 61. These photovoltaic panels 61 make it possible in particular to supply electrical energy, for example for the treatment and / or filtration device 31, the distribution pump or the pumping device 50. Batteries and an electrical control and management circuit may in particular be arranged in the technical room 31. The water storage building 1 may also be connected to the electrical distribution network in order to restore the surplus electricity generated or its own needs.

[0041] As shown in Figures 3 and 4, the roof 60 of the water storage building 1 can in particular include an overhang 62. The at least one water-consuming device 40 is then preferably arranged under this overhang 62 in order to be protected.

[0042] In a first embodiment illustrated in Figures 3 and 4, these sanitary devices 40 are for example at least one shower 40a, at least one toilet 40b or at least one mist sprayer 40c. Here, each water-consuming device 40 is arranged on a specific side of the water storage building 1.

[0043] According to a second embodiment illustrated in Figure 5, the at least one water-consuming device 40 is one or more drinking troughs 40d. In this second embodiment, the water storage building 1 can in particular be camouflaged to integrate as well as possible into its environment and disturb the landscape and wildlife as little as possible.

[0044] The water storage building may also include other types of sanitary devices 40 such as at least one water outlet such as taps or connections for firefighters.

[0045] It is also quite possible to imagine a water storage building 1 having a single type of water consuming device 40 or a combination of several types.

[0046] The water storage building 1 may in particular be intended to be installed on roadside rest areas, campsites, near beaches, urban parks, on golf courses, wine estates, farms, near industrial buildings, collective or individual buildings, near sensitive areas (maquis, forests, garrigues), in order to store and reuse water for different purposes, depending on the periods and needs.

[0047] For example, during periods of water shortage, misting can be used to cool down without consuming too much water from the environment. Showers, toilets, watering vegetation (in line with eco-urbanism and the development of depolluting and soothing green areas), and cooling urban spaces also consume less water from the environment thanks to storage. This allows, for example, to preserve vegetation in the city or to provide food and drink sources for flora and fauna.
