Sprinkler irrigation is a method of applying irrigation water to the
agricultural field in a manner similar to natural rainfall. A system of
pipes is needed for water distribution which is usually by pumping. The
sprinklers are used to spray the water into the air through
so that it breaks up into small water drops which fall to the
ground. It is necessary to properly design the pump supply system, sprinklers and operating conditions
in order to enable a uniform application of water.
The essential components of a typical sprinkler irrigation
system are Pump unit (usually a centrifugal pump which takes water
from the source and provides adequate pressure for delivery into the
pipe system), Mainline and sub-mainlines (pipes which deliver water
from the pump to the laterals), Laterals (deliver water from the
mainlines or sub-mainlines to the sprinklers)
and Sprinklers (to spray water in the form of small drops)
Sprinklers irrigation system can be applied to any type of soil
but it is best suited for sandy soils with high infiltration
rates. It is advisable that the average
application rate from the sprinklers (in mm/hour) should be less than the basic infiltration rate of the soil
in order to avoid surface ponding and runoff.

Sprinklers are not suitable for soils which easily form a crust.
If sprinkler irrigation is the only method available, then light
fine sprays should be used. The larger sprinklers producing larger
water droplets are to be avoided.
