Drip Irrigation Systems

Drip Irrigation

Drip irrigation system is one that emits drips of water at regular intervals usually applied at the surface of the soil and after a period of time those drips will have wet the soil enough for it to spread out and down enough to reach the root zone of the nearby plants.Read more.

Drip Tubing

The emitters can be manufactured into a plastic tube, which is called drip tube. This tube has emitters (not just holes in the tube) at regular distances from usually 0.3M, .04 to 0.5M and each emitter is designed to emit a certain volume of water per hour. This will generally vary from 1.6L/H to 3.0L/H. It can be pressure compensated to ensure that the same volume of water comes out of each hole regardless of whether it’s at the top of the garden or at the bottom.

Drip tubing is easy to install because it normally just sits on top of the soil and is positioned close enough to all the plantings so the roots of all the plants are close enough to reach the water. Ideally this drip tubing or dripline as it is commonly called is covered with mulch to retain the moisture in the ground in warm weather.

Individual Drippers

For those that don’t have reasonably regular distance between plantings or varying heights of plants (such as in pots) you can just use low density (LD) poly tubing to run from one point to another and individual drippers can be connected to this pipe (either directly into the pipe or through smaller more flexible tube) at intervals that suit the planting.

Whichever way it’s done in a good drip irrigation system there needs to be pressure applied to the water in order for it to come out of the drippers. This pressure usually (in the case of most households) comes from the mains or it could be from a water pump connected to a tank.

Advantages of Drip irrigation System.

The drip system, whilst not perfect, did overcome many of the inefficiencies of the spray system:

  • Reduced evaporation due to the drip line being under the mulch (ideally)
  • Reduced weed growth by not putting water in areas not requiring water
  • Totally eliminated the wind drift issue
  • Avoids run off because the water is emitted so slowly that it has a chance to soak into the soil rather than pool and run off
  • More efficient for the same reason when irrigating sloped areas
  • Eliminated overspray problems because there is no spray
  • Reduced water consumption when designed correctly and the right run times are programmed.
  • Delivered water directly to the root area of the plant where it’s needed the most

Drips systems are normally very automated in that they are controlled by Irrigation Controllers and set to come on and off at set times, depending on how much water you believe the plants need.
