New automatic irrigation system

Automatic sprinklers are the ideal solution to avoid chores of watering and make sure you have a green and well-irrigated garden, even when you are away for a long time, for example during the holidays. There are mainly three types of automatic irrigation systems: micro-irrigation systems, surface systems and underground systems. Each type of sprinkler has its advantages and the choice is made considering the needs of the garden.

Automatic watering: general principles

An automatic watering system takes care of the daily chore of watering thanks to a programmer which controls and triggers the sprinkler. The program can be set at regular times and intervals for a specified duration. Behind this generic name are systems ranging from the simplest to the most sophisticated, which can operate at low pressure (for micro-sprinkler systems and micro-irrigation for example) or at normal network pressure (between 3 and 7 bars).

When and why use an automatic watering system

Automatic watering systems are very practical when you are absent, for example when you go on vacation, since they can take over in the maintenance of the garden. Used throughout the year, when watering needs are felt, they can helpsave up to 50% water, and thus prove to be a profitable investment for anyone wishing to monitor their water consumption.

Automatic watering systems

We also speak of "flying systems" for these automatic sprinklers on the surface. Their operation is simple: pipes are laid on the ground and feed sprinklers of different types that water the garden by sprinkling. The diameter of the chosen pipes depends on the pressure of the water that will circulate and the flow of the sprinkler used. For large pressures, a 12.5 mm pipe will be chosen for medium pressures, a 15 mm pipe, and for low pressures a 19 mm pipe.
The programmer (battery or battery) is located on the tap (it will be fixed, and its possible clock, at the nose of the tap).
The hose is stored on a reel and connected to a circular sprinkler, sprinkler or rotary jet (for large areas).

  • Advantages: inexpensive, easy to install, easy to move.
  • disadvantages: unattractive, frequent leaks, obligation to move the sprinkler and hose.

Automatic sprinkler systems buried

These are the most complex systems, since they require buried pipe network. They are mainly intended for large grassed areas that need a regular watering.
We distinguish:

  • systems to power terminals, distributed in the garden, on which can be connected a hose and a surface sprinkler;
  • systems to retractable nozzles or no.
The range of sprinklers varies depending on the model and its nozzles (retractable in the ground too) say "low consumption" allow good flow management, which will not flood the soil and roots. It is the pressure exerted by the water in the pipe system that pushes the nozzles out of the ground. There are two types:
  • nozzles;
  • the turbines.
It is not recommended to connect the two types of nozzle on the same pipe network, the watering would not be regular.
  • Advantages: effective, suitable for large areas, invisible;
  • disadvantages: digging trenches to bury the system, obligation to call a professional for prior technical study and implementation, cost.


Cousin of the surface watering, the micro-irrigation (or drip irrigation) is a localized watering technique. By misting or micro-sprinkling, a network of specially designed pipes meanders on the surface to water plantations that should not be exposed to too much water. This system is ideal in vegetable gardens or flower beds.
There are complete and sophisticated systems of micro-irrigation which allow to associate various accessories (self-regulated drippers, micro sprinklers adjustable flow, solenoid valves, regulators) for optimal watering and perfectly calibrated.

  • Advantages: watering very well adapted to the plantations of the garden, good control of the flow and the consumption;
  • disadvantages: complex and meticulous adjustments, risks of leakage.

Easy watering thanks to connected objects

The programming using electronics is not new in watering. For a long time, we have found in the trade of programmers more or less sophisticated, faucet nose or control sprinkler systems buried rely on theelectronic.

  • Home automation, more and more widespread in the house, is also entering the garden, and it is very convenient! Thus, connected objects combine with traditional techniques to facilitate garden maintenance:
  • a connected weather station is very convenient for adapting the amount of sprinkler water to hygrometric forecasts;
  • the connected watering programmers, directly connected to the nose of the tap, allow a millimetric support of watering. Very affordable, they allow to refine the settings of the irrigation program, even when remote:
  • the pluviometric probes connected report watering needs according to the weather. They avoid watering when the rainfall allows to dispense with it.
These systems allow not only time saving not negligible, but they also make it possible to water savings important, since you water your garden more than when it is really necessary! To ensure optimum watering of the plants, a "smart assistant"will take into account essential factors such as the type of garden soil, the species of plants to be watered or their location and exposure, and the system will be able to handle other automated equipment such as a robotic lawnmower.
