Pumps.

World Vision, an international Christian humanitarian organization, has been working for nearly three decades to bring clean water to the most remote areas of the world, and with the invention of a manual, smaller plastic pump, the relief organization is hoping to expand its clean water outreach even farther.The pump, according to Randy Strash, World Vision's water, sanitation, and hygiene strategist, consists of a small, plastic PVC pipe and PVC fittings which costs only $25 to assemble, compared to $700 to $800 for standard stainless steel pumps previously used in many parts of the world.
