Hi all, I am planning my irrigation system with Hydrosys and I would like to make it as efficient as possible. I want to collect rain water to then use it to irrigate my meadow and plants/bushes.

The idea is to use a water tank to be positioned underground, something like this:

Below the simple scheme I have in my mind:

Let's say I want to water my bushes and plants, in this situation the power of the pump should be just enough to guarantee a drip irrigation along the lines 1 & 2 in the scheme (for sprinkler watering the power should be calculated according to the meadow's size). Pump could be either external to the tank or a submersible one. In case of the submersible option, valve no.1 should be moved after the pump outside the tank.

1) Planned irrigation starts

2) Hydrosys, by using the ultrasonic sensor, detects the level of water in the tank. Now you can have 3 different scenarios:

3) If the water in the tank is above a set minimum level, it opens valve no.1 and switches on the pump. It opens also the valves for line 1 and 2, plants and bushes get watered and are happy

3a) If water goes below a minimum level, the ultrasonic sensor detects it, Hydrosys stops pumps and closes valve 1. At the same time it switches the water supply to aqueduct, by opening valve no.3, irrigation continues until the end

3b) If water is already below the minimum level, the ultrasonic sensor detects it and Hydrosys switches the water supply to aqueduct, by opening valve no.3, irrigation continues until the end

4) End of irrigation, closing of all valves / switching off the pump (if case of scenario in point no.3)

Questions:

• can an ultrasonic sensor be added to the system? In my situation i would need a sensor to tell me how much water is inside the tank, as it's positioned underground

• can the water supply be switched from tank to aqueduct according to the different levels of water inside the tank?

• Is there anything right in what I have been describing so far? :)

All suggestions and feedbacks are welcome :)
