The mission of IDE, is to create income opportunities for poor rural households. Downloads related to various technologies being promoted by IDE (treadle pumps, rope pumps, water storage systems) include a very informative drip irrigation manual that can be accessed

IDE views productive water as the entry point to creating income opportunities for some 900 million people. We identify locations where improved access to water can have a positive impact, and then offer affordable technologies for lifting, storing, and distributing that water.  IDE also looks for ways to reduce on-farm costs and increase margins available from market access and post harvest activities.
