Lift Irrigation System is a mechanical way of irrigaing the higher level land which cannot be irrigated by gravity water. Different structures like canal, barriage, cross drainage structures etc. are built due to which the land lower than the dam level could be easily irrigated but the land higher than the dam level always got dry and bare. So, this system is introduced so that the higher level CCA can also be irrigated and productivity can be increased.
How the system runs ?
First, dam or weir is constructed for the collection of water. Then by the help of pumps, water is transported to the top of the higher level land and stored in main delivery chamber (water storage). From there water is again pumped to irrigate the land or crops. Generally, pipes are layed underground from where plants get water continously at the required rate which can be controlled as per necessity.
Advantage
Higher Level land can be irrigated.
Water loss is less like evaporation loss.
Land acquisition is less.
Less number of manpower is required.
Disadvantage
Pumps of high capacity is required as per the altitude difference which needs high energy.
It is costly method of irrigation.
