Homemade water filter from sand and gravel
A simple water filter made from local resources - primarily sand, gravel and cement - and costing around US$30, can remove over 90% of many common water-borne pathogens. BioSand filters can also clean up to 80 litres of water each day, making them ideal for use by individual households. Following community-based training in several countries, including Kenya, Uganda, Zambia and Sudan, some groups have even started using the filters to generate income from sales of clean water. Gilbert Olakashem of Connect Africa, an organisation promoting the filters, explains more to Wambi Michael.
