Run-off Storage in Sand Reservoirs as an Alternative Source of Water Supply for Rura land Semi-arid areas of South Africa

Authors: Olufisayo A. Olufayo, Fred A. O. Otieno, George M. Ochieng

Abstract:

Abstraction of water from the dry river sand-beds is well-known as an alternative source of water during dry seasons. Internally, because of the form of sand particles, voids are created which can store water in the riverbeds. Large rivers are rare in South Africa. Many rivers are sand river types and without water during the prolonged dry periods. South Africa has not taken full advantage of water storage in sand as a solution to the growing water scarcity both in urban and rural areas. The paper reviews the benefits of run-off storage in sand reservoirs gained from other arid areas and need for adoption in rural areas of South Africa as an alternative water supply where it is probable.

Keywords: Groundwater, Perennial river, Run-off storage, Sandreservoir.
