Sand-Trapped Water Reservoirs: Alternative Technologies for Freshwater Augmentation in Remote Communities of South Africa

Abstract:     
South Africa water resources are scarce in global terms with mean annual rainfall 50 per cent less than world average of 860 mm/a. On the other hand, increasing economy development and resulting contamination of water resources further reduced water availability. The conventional water resources (largely surface water) in the country have been fully exploited. So therefore, new methods are needed to make limited water resources available. High evaporative losses from surface storage, increasing costs of large dams and aridity conditions make development of unconventional sand water storage appealing for freshwater augmentation.
