Sprinkler Irrigation

 
 
What is Sprinkler Irrigation System?
Sprinkler Irrigation is a method of applying irrigation water reproducing in a controlled manner the rainfall. Water is sprayed into the air and irrigate entire soil surface through spray heads so that it breaks up into small water drops spreading over the ground.

Sprinklers provide efficient coverage for small to large areas and are suitable for wide range of crops and are adaptable to nearly all type of soils as they are available in a wide range of discharge capacity.

Sprinkler system are  designed to ensure maximum water saving, combining high quality, affordability and ease of installation. Components  are essentially made of high strength & chemically resistant engineering plastics to achieve functional satisfaction and favorable cost economics.

Application:
Suitable for wide range of  field crops like Wheat, Gram, Pulses as well as Vegetables, Cotton, Soya bean, Tea, Coffee, and other fodder crops. Suitable for Residential, Industrial, Hotel, Resorts, Public & Government Enterprises, Golf Links, Race courses.

Sprinkler System is subdivided in to Rain Gun, Centre Pivot and Lateral Move System

Centre Pivot:
In the center pivot system, sprinklers are placed along a series of arched pipes which is pivoted at one end, and moved around the field in a circular fashion. Central pivot irrigation is a form of overhead (sprinkler) irrigation consisting of several segments of pipe (usually galvanized steel or aluminum) joined together and supported by trusses, mounted on wheeled towers with sprinklers positioned along its length. The system moves in a circular pattern and is fed with water from the pivot point at the center of the circle. The outside set of wheels sets the master pace for the rotation . Centre pivots will cover surface in relation with the number of arches , and supporting tower , up to  500m in length (circle radius) with widely used  size being the standard 1/4 mile machine (400 m) covering 125 acres

Most center pivot systems are equipped with  drops hanging from a u-shaped pipe called a gooseneck attached at the top of the pipe with sprinkler heads positioned a few feet (at most) above the crop,  limiting evaporation  losses and wind drift. Drops can also be used with drag hoses or bubblers that deposit the water directly on the ground between crops. This type of system is known as LEPA (Low Energy Precision Application) and is often associated with the construction of small diking  along the furrow length.

Crops may be planted in straight rows or sometimes in circles to conform to the travel of the center pivot in crops like cotton. Movement of each tower is secured by either  hydraulically  driven systems or  electric motor-driven systems mounted at each tower , and specific tyre dimension can be fitted to specific soil profile

Linear Move:
Similar structure  can also be configured to move in a straight line, where the water is collected  from a central ditch / Canal . In this scenario, the system is called a linear move irrigation system.
