During the dry season, Hwange’s water resources are limitated, so 14 pumps within 523km² concessions must be maintained and refuelled daily to ensure a vital water supply for Hwange’s wildlife. They run continuously from April to Novembre until the summer rains arrive. Elephant water need is a major task because about 70 000 litres of water per pump per 24 hours are necessary. Old diesel-run generators are replaced with solar pumps in order to reduce carbon footprint.
