Water user associations are groups and formal organizations of farmers that provided managements for the whole or parts of the irrigation and drainage network. These have been created for organizing farmer in the legal frame work, and taking part in the effectiveness constructions, operations, developments and maintenance of facilities and water supply network. National irrigation systems, serving a large number of small paddy farmers, require water users’ organization for effective and sustainable joint management.
