Elevation irrigation is an irrigation method in which water is not transported by natural flow (as in gravity fed channels), but is lifted by pumps or other means. Lifting systems must fulfill two main tasks: firstly, to pump water from the water source to the main supply chamber, which is located at the highest point in the control area. Second. This water must be distributed to the beneficiary farmers' field through adequate and adequate distribution. Elevation irrigation is an irrigation method in which water instead of being transported by natural flow (as in gravity fed channels) requires external energy through animal fuel, fuel or electric energy using pumps or Other mechanical means. Pedal pumps, although an ancient method of raising water for small heads have recently been modernized and used in a large way
Lifting systems must fulfill two main tasks: firstly, to pump water from the water source to the main supply chamber, which is located at the highest point in the control area. Secondly, they must distribute this water to the beneficiary farmers' field through an adequate and adequate distribution system. The source is mainly groundwater, river streams, contour channels, ponds and lakes.
For a viable irrigation lifting system, the requirements are the constant water source must throughout the irrigation season on the site and the feasibility to raise the water to the desired location. Different pumps are required depending on the head of the service point and the discharge. The principal of the thermization may be steel, concrete or any other suitable material. Lifting irrigation systems are useful when the target land is at a higher level.
The system of irrigation by elevation is fundamental to stabilize the agricultural production, especially in the years of drought, and to increase the production of foods, since the water is available when it is necessary and, therefore, the level of income increases. Lifting irrigation systems are individually owned or belong to a group of farmers in a cooperative mode. For successful operation, elevation irrigation schemes require appropriate technique, planning, design and execution through a well-informed technical person. The participation of the beneficiaries is absolutely necessary. Unplanned development of elevator irrigation systems has the potential to have an adverse impact on groundwater levels, as has been the case in many South Asian countries in recent years. Continuous dropping of the groundwater surface makes the cost of running and maintaining the irrigation systems more elevated. Cooperative elevation irrigation systems have the potential to be participatory in development and management. The submerged multi-stage pump is at the heart of any irrigation system.
