Elephant pump
The Elephant Pump, designed by Pump Aid based on a 3,000-year-old Chinese design, is built from rope, a plastic pipe, some rubber washers, and a winding wheel. The name "Elephant Pump" refers to the device's strength, shape, and reliability. The pump can lift water from depths of 50 meters (160 ft), and can produce 1 litre (0.26 US gal) of water per second.
The Elephant Pump's design won the 1995 St Andrews Prize for the Environment for Pump Aid. The World Bank awarded a Development Marketplace grant in the amount of 120,000 United States dollars to Pump Aid in 2006, funding 1,000 pumps and enabling the development of the Elephant Toilet. The Elephant Pump has now provided over 1 million people in rural areas of Zimbabwe and Malawi with clean, safe water. Elephant Pumps can be maintained by poor rural communities without any assistance.
Pumps are built in response to grassroots demand and in full consultation with the local community. The local community come together to assist in the building process, providing materials such as bricks, sand, stones and unskilled labour. The Elephant Pump can also supply water for irrigating nutrition gardens where communities can grow crops to improve their diet and sell the surplus.
Construction, operation and maintenance
To break the cycle of poverty in Africa, access to clean water for drinking and water for irrigation must be improved. Pump Aid builds appropriate technology water pumps, called Elephant Pumps that can be maintained by poor rural communities without any outside assistance.
