An irrigation system that delivers small-sized water droplets through a rotating head allowing longer watering time with less runoff

Micro-sprinkler irrigation is an efficient and alternative method of irrigation for high value cash crops. It has been demonstrated in the Jhikhu Khola watershed (JKW) in Nepal’s middle mountains by the People and Resource Dynamics in Mountain Watersheds of the Hindu Kush-Himalayas Project (PARDYP). The NGO International Development Enterprises (IDE-Nepal) has assisted private companies to assemble and market micro-irrigation systems.

Micro sprinklers are available in a variety of configurations. They operate at a lowpressure, with water delivered at a pressure equivalent to 10-20m of head, and at a low discharge rate of 0.1-0.2 lps – equivalent to the average discharge of a 1/2 inch size public tap. A pre-assembled micro-irrigation system generally consists of 4 to 8 sprinkler heads at 4m intervals connected by half inch piping. Micro sprinklers are most suitable for closely cropped vegetables like onion and garlic.
