Irrigation projects are the projects that are planned for various purposes like irrigation, hydropower generation, water supply for drinking and industrial purpose, flood control navigation etc. which are the types of multipurpose projects. The Projects which serve more than one purpose are called as multipurpose projects. Generally, the majority of multipurpose projects are the combination of irrigation and hydro-power. There are many irrigations, hydropower and multipurpose projects which were approved initially as independent projects. Subsequently, due to interstate agreements and new projects coming up on downstream and upstream, water planning was done in such a way that operation of these projects are now done in an integrated manner. Such types of projects are now being called as irrigation, hydropower, multipurpose and complex.
