Since Kalahari Plains is in a very arid area, it is vital that we conserve water. We have installed water-harvesting tanks at each tent and other fixed structures to collect rainwater during the rainy season. When all tanks are full (thanks to the 115 mm of rain a year), the camp has 150 000 litres of additional water, reducing the need for borehole water during this period. The borehole water drawn from beneath the camp is very salty, not drinkable and is used in the pool and for showering. Therefore, we have installed a state-of-the-art Reverse Osmosis desalination system to produce clean drinking water as well as for cooking.
