Abstract: Self-contained ecological watering system, protected against obturations, and capable of irrigating at low cost uniformly and regularly a variety of cultivated areas; the system operates automatically a series of fertirrigation cycles requiring minimum actuation power and reduced water flow rate. The system permits implementation of various configuration including a plurality of local subsystems (1) which are controllable locally or from a remote station (6); each subsystem comprises a container (2) capable of accumulating the volume of liquid to be discharged per cycle, a watering assembly (3) capable of regulating the watering volume and discharging it upon receiving a low power signal; a low consumption electronic control unit (4) capable of determining the frequency and the appropriate time to send said signal; and a low restriction distribution network (5) capable of transporting the water to irrigate the locations in need.
