HoverAid use Bio-Sand-Filters (BSF) to filter water at a home level. BSF use both biological and physical filtration methods, ensuring the water is cleaned to a high level. BSF's typicaly reduce water turbidity to <1.0NTU, have success rates of over 95% and can eliminate coliform bacteria. They are also free and easy to maintain, durable, cost effective and being owned on a house level removes ownership issues. The Bio-Sand-Filter is an excellent way of allowing clean drinking water into a home, enabling water to be used when it is needed, and not being contaminated after collection.
Bio-Sand-Filters are so effective because of their simplicity. See the diagram below to see how each element of a bio-sand-filter works together to create a simple but efficient water filter.

Canzee Water Pumps
HoverAid have successfully installed 15 water pumps in the Beroroha and Ankavandra regions in Madagascar. Our projects enable the local people to help themselves, by assisting them in creating clean drinking water sources for their villages. Once a village has approached HoverAid asking for clean drinking water, HoverAid ask that the village collectively choose a communal site for the well/bore hole and dig down to find water. Once this has been achieved HoverAid then assist local workers, teaching them how to safely line the well/bore hole to keep the water as pure as possible. HoverAid work to sustainably introduce the most appropriate way to provide clean drinking water. We then provide the most suitable pump for the village, and teach the community how to maintain, install and fix the pump should it fail.
The Canzee pump is unique: it does not require maintenance even with intensive use. There are no parts that require adjustment, lubrication or special attention. In addition production of spare parts and repairs may be performed by the villagers themselves. In addition, villagers also contribute a token amount for the parts of the pump (normally totalling around 0.05% of the actual cost) to show their value of the item. This money is then used as a fund for spare parts in the future. One pump can typically serve around 300, providing clean drinking water for drinking, food preparation and hand washing.
The parts of the pump cost £1,335, and the education, installation and transport of parts costs a further £1,165. The cost of one pump, fully installed is £2,500.
