Powered pumps refer to pumps that are powered by sources such as: solar, animal, wind, diesel or biogas fuel, water, as well as suction, piston, centrifugal, and diaphragm technologies. The natural methods (wind and solar) are the most environmentally sustainable, yet may have greater initial costs. The hydraulic pump is both sustainable and inexpensive, yet must operate where a difference in water height occurs, e.g. mountainous areas. Some of the other pump technologies require specific maintenance that communities should be prepared for. Some pumps are better suited for community use and some for household use. Most pumps have depth limitations, so be sure to check how deep they can retrieve water.

Smallholder irrigation could change the lives of millions of people
Smallholder farmers in sub-Saharan Africa and South Asia are increasingly using small-scale irrigation to cultivate their land. Individually owned and operated irrigation technologies improve yields, reduce risks associated with climate variability and increase incomes, allowing farmers to purchase food, health care and education. There is great potential for many more farmers to benefit from small-scale irrigation. This report presents governments, donors, lending institutions, the private sector and farmers with the opportunity to make well-informed decisions about investments in agricultural water management (AWM) that could change the lives of millions of rural people.
