- the tank 2 collector is adapted to collect the rainwater stored in the tanks 1 principal and 3 secondary. The evacuation of the water present in the tank 2 collector is possible only when the valve 23 is in the open position.
- the drain battery 5 can capture the groundwater and channel it to the collection tank 2 for temporary storage and transfer to the main tank 1.
- each drain 5 extends to the main reservoir 1.
- the end of each drain 5 opening into the main tank 1 is advantageously obstructed by a cap 71 screwed and screwed, so that in normal situation, the water can not flow between the reservoir 2 collector and the main tank 1 5.
- each cap 71 screwed and screwed of each drain can be unscrewed. by a human operator present in the main tank 1 to proceed with the cleaning of this drain 5.
- the drain battery 5 makes it possible, on the one hand, to evacuate the water present in the collecting tank 2 and on the other hand to collect groundwater and to transfer it to the main reservoir 1 via the transfer line 12 .
- the tanks can be made of a variety of materials.
- the tanks are made of a material selected from concrete, recyclable polyethylene and polypropylene, and equivalent materials.
- the tanks of the hydraulic station according to the embodiment of Figure 4 are all concrete.
- the secondary tank 3 of the hydraulic station according to the embodiment of FIGS. 2 and 3 is made of polypropylene.
- this polypropylene secondary tank 3 is preferably surrounded by a layer of geotextile, itself surrounded by a geomembrane 36, itself surrounded by a second layer 37 of geotextile.
- the geomembrane 36 is ventilated by a ventilation duct 17 arranged between the geomembrane and the access column 63 of the secondary tank 3.
- a hydraulic station comprising a secondary concrete tank 3 may further comprise, as shown in FIG. 4, a vertical drain 55 extending outside this secondary tank 3 along the vertical.
- This vertical drain 55 is connected at each of its ends, upper and lower, to a pipe 56, 57 opening into the secondary tank 3.
- the upper pipe 56 is equipped with a valve 29 adapted to allow / prohibit a circulation of water in this pipe 56, so that this vertical drain 55 can ensure a discharge of a portion of the water stored in this reservoir 3 secondary by an opening of the valve 29, or collect underground water present in the vicinity of the secondary tank 3.
- the lower pipe 57 may also be equipped with a motorized valve controlled by the controller 4 to allow or not the collection of water by the vertical drain 55.
- a secondary concrete tank 3 may comprise a battery of vertical drains.
- the water stored in the main tank 1 and the water stored in the secondary tank 3 can be evacuated via this vertical drain or a battery of vertical drains.
- each vertical drain 55 is preferably coated with a geotextile felt, itself embedded in sand.
- FIG. 5 shows a schematic view of a horizontal drain battery arranged between the subsoil and the collector tank 2.
- This drain bank 5 comprises a plurality of drains, each drain 5 extending horizontally between the ground and the collector tank 2.
- Each drain 5 can be of all types of shapes and structures and be made of a variety of materials such as PVC, polyethylene, concrete, terracotta, and equivalent materials. Each drain may be surrounded by a sand filter or equivalent filters. Preferably, each drain 5 is coated with geotextile so that the drain can provide filtration functions of the water it collects and discharges.
- each end of a drain 5 arranged in the ground is obstructed by a plugged and bonded buffer 91, so as to prevent the penetration of earth into this drain 5.
- each layer of geotextile coating a drain 5 is itself covered with a layer of sand.
- each drain 5 of the drain battery 5 may be associated with one or more valves 23, or one or more valves 23 may regulate the operation of a combination of drains 5.
- drain battery 5 A number of configurations of the drain battery 5 are possible and are not described here in detail.
- a battery of drains 5 according to the invention can be installed directly in the ground or be part of a prefabricated element.
- a hydraulic station according to the invention comprising a main tank 1, a collector tank 2 and a bank of bidirectional drains 5, is a new, efficient, parameterizable and automatic solution for recovering, managing and distributing rainwater runoff and groundwater .
- a hydraulic station also comprises a rainwater treatment station arranged upstream of the inlet pipe 10.
- a treatment station can comprise water screening means adapted to separate water from large waste such as pieces of wood, plastic bottles, cans, etc. These screening means are typically made by grids.
- a water treatment station may also comprise coagulation means, flocculation means and settling means.
- a treatment station also comprises means for filtering water, for example using sand, crushed or rolled, anthracite or activated carbon.
- a hydraulic station according to the invention thus contributes to the safeguarding of groundwater and generally to the preservation of natural water resources by allowing the collection, treatment, and distribution of rainwater suitable for supplying devices that do not require drinking quality water.
- a hydraulic station according to the invention is therefore particularly adapted to the needs of secondary waters of an individual, an industrialist, an agglomeration, etc.
