What is Sprinkler Irrigation System

Sprinkler irrigation system is a method of irrigation among many other methods such as drip irrigation, canal and ditch irrigation, and automatic sprinkler system whereby water is sprayed on the land surface in the form of artificial rain. To create the precipitation, which is the application of water to a specified area, water under pressure is ejected via the nozzle of a sprinkler system device. Sprinkler heads can be categorized into two: small and large.

What to Consider During Installation

There are a few factors that need to be taken into consideration when it comes to installing the right sprinkler irrigation system.

  • Wetting circle refers to the circular area on the ground where the projected water from the sprinkler head covers. The diameter of the wetting circle is also often termed wetting diameter.
  • The radius of throw is the horizontal distance between the sprinkler head position and the farthest point that the projected water can reach. The precipitation rate decreases as the point of precipitation gets further from the sprinkler head.
  • Next is the uniformity of water application which measures how uniformly the water is falling on the ground. 70 percent coverage is generally acceptable water distribution uniformity.
  • In reality, obtaining desirable water distribution uniformity is often very hard. Therefore, it is always a good practice to utilize two adjacent sprinklers spaced in such a way that there is some overlapping of the precipitation. A rule of thumb is to keep both sprinklers 60% to 70% of the wetting diameter apart.
  • Water pressure is the main energy in operating the sprinklers. The two common ways of obtaining water pressure are to use either the gravity or by pumping. It is imperative to bear in mind that too high or too low of a pressure is highly undesirable for sprinklers operation as it can severely affect the watering application uniformity.
  • Water discharge or flow rate is the volume of water collected over a specific duration of time, often measured in liters per second (lps). Every sprinkler needs to fulfill a specific minimum discharge for the effective operation which you can find in the product specifications.
  • Last but not least, the precipitation rate is the average height of water collected on the ground over a duration of time specified, measured in mm per hour. A precipitation rate higher than the intake rate of the soil will cause runoff, especially in heavy soils and uneven surfaces such as slopes and terraces. Generally, small sprinklers have a slower application rate and so cause less runoff damage.

What is Precipitation Rate?

Precipitation rate refers to the speed at which water is being applied to a particular area. Small sprinkler heads have a smaller radius of throw. It can be adjusted to operate at low pressure and flow conditions. This reduces the possibility of soil erosion and is very useful when irrigating a small piece of uneven land with narrow terraces.
