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.

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.

<!--The pump is hand powered powered, but can be adapted to wind, solar or even a bicycle. 21 other African countries have lined up to implement similar projects. The core program of pump building in Zimbabwe has grown with 432 Elephant Pumps installed in 2012 compared to 367 in 2011. This is now a massive program with the Elephant Pumps, managed by [http://www.theafricatrust.org/ The Africa Trust], providing clean water for over 10% of the entire population of Zimbabwe. In addition to the core staff, it has been possible to provide contract work to over 40 other individuals during the course of the year.-->

 

Pump Aid believes that each pump is at the heart of sustained water and sanitation improvement.

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. Using technology that has local currency, the well is built with local sand, stone and handmade bricks. The rope plugs, integral to the design, are made by melting and moulding local waste plastics.

===Costs== The cost of an Elephant Pump is a combination of two elements: ‘Hardware’ and ‘Installation’. The total cost of providing the hardware for the Elephant Pump is around £600, with small variances on items such as cement from country to country. The cost of installation can vary from country to country and region to region. It includes items such as survey cost, well digging, bricks, occasionally blasting and in country costs of staff and fuel etc. As a benchmark these have averaged in Malawi, for example, at £3000 per Elephant Pump installation.=

According The cost of an Elephant Pump includes a full range of programme activities from installation to [http://www.treehuggercommunity training.com/clean-water/elephant-A single pump-wins-award.html Treehugger.com], serves a pump community of up to serve 500 120 people can be made for a total cost of and costs on average about £200 ($350 USD)£3, with the major components having a lifespan of 50 years000.
