Dams in South Africa

Abstract

Dams in South AfricaDams in South Africa I n South Africa we depend mostly on rivers, dams and underground water for our water supply. The country does not get a lot of rain, less than 500 mm a year. In fact, South Africa is one of the 30 driest countries in the world. To make sure that we have enough water to drink, to grow food and for industries, the government builds dams to store water. A typical dam is a wall of solid material (like concrete, earth and rocks) built across a river to block the flow of the river. In times of excess flow water is stored behind the dam wall in what is known as a reservoir.
