The following is described in detail operation of a hydraulic station according to the form of embodiment of figure 2.

Main tank 1 is adapted to collect rainwater from the stream carried by the entry 10. These waters can be stored in the reservoir main 1 or be evacuated directly by one or several pumps 7 submerged or not submerged towards irrigation networks or towards specific uses via the outlet duct 11.

Waters stored in the main reservoir 1 can be transferred to collecting tank 2 using the transfer conduit 12, which is accessible by virtue of a valve opening order 22. These transferred waters are already either stored in the collection tank 2, or evacuated by the battery drain pipes 5.

Waters stored in the main reservoir 1 they can also be transferred to the secondary deposit 3 using the storage duct 18, which is accessible under a valve opening order 28. These waters transferred are then stored by the secondary deposit 3.

According to a particular embodiment and such as depicted in figure 4, the waters stored in the main deposit 1 can also be transferred to the deposit secondary 3 by means of a second storage duct 88 which is arranged between the main deposit 1 and the deposit secondary 3. According to this embodiment, access to this second storage duct 88 does not depend on a valve motorized

Thus, the secondary tank 3 is adapted to store water contributed by the main tank 1. These Stored water can be transferred to collecting tank 2 using the secondary transfer conduit 14, which remains accessible under a valve opening order 24. These waters can then be evacuated by the battery of tubes drain 5, which is accessible under an opening order of the valve 23.

These waters stored in the reservoir secondary 3 can also be reintroduced into the deposit main 1 using the storage duct 18, which It is accessible by opening the valve 28.

The collection tank 2 is adapted to collect rainwater stored in the main reservoirs 1 and secondary 3.

The evacuation of the water that is present in the collecting tank 2 is not possible except when the valve 23 is in open valve position.

In addition, when the valve 23 is in the position of valve open, the drain tube battery 5 can pick up the groundwater and channel it to the collecting tank 2 to be temporarily stored in it and transferred to the warehouse main 1.

It should be noted that the double meaning of water circulation in the drainpipe battery ensures a self-cleaning of the drain pipes 5.
