__NOTOC__ <small-title />
The Canzee hand pump is a direct-action handpump made with corrosion resistant materials such as plastic, stainless steel and wood. The pump uses two PVC pipes inside each other, each with a simple non-return valve made with a rubber flap.
The Canzee pump was first developed in New Zealand by Owen Jones, and was further developed by Richard Cansdale of [http://www.swsfilt.co.uk/ SWS Filtration] in the UK. Organisations that work with the Canzee pump include Bushproof and Wells for Zoë. The pump is extensively used in Madagascar.
===Suitable conditions ===
The Canzee pump is suitable for use in shallow wells and underground tanks. It pumps from at least 10 meters, and pumps about 20 liters per minute.
===Construction, operations and maintenance===

The pump consists of two PVC pipes of different diameter, one inside the other. At the bottom of each pipe is a non-return valve made with a rubber flap which allows water to enter the bottom of the pipe, but not out again.

===Costs===
For the specific Maroantsetra installations project in Madagascar, MEDAIR has evaluated the installation costs. According to the National Director, Christophe Roduit, pump purchase including transport costs from England to Maroantsetra, administrative support and installation, their total
investment was around 700 Euro per pump installed in Maroantsetra (this price includes the pump cost of 310 Euro and the extra cost for the larger apron).
The pump users contributed with delivering of materials (gravel and sand) and provided labour. Because of the emergency nature of the project and the rapid and simple installation methods used, the beneficiary contribution was small in financial terms.
===Field experiences===

The NGO MEDAIR has been active in Madagascar since 2002, and is the first to have installed a large number of Canzee pumps. They worked in the Maroantsetra region in Madagascar in hydrogeologically suitable communities in the rural areas. They found that in previous projects, not enough attention was paid to environmental issues. Especially in the context of installation in shallow wells, more careful siting is needed. <ref>[http://www.rural-water-supply.net/en/resources/details/173 The report by MEDAIR can be downloaded here]</ref>
