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.
