Gauteng in South Africa has limited natural water supplies of its own, so its vital that we conserve every drop we have. The undertaking of a Water Demand Management programme to save water through the efficient use of water is not a luxury but an absolute necessity. Only a serious commitment to Water Demand Management (WDM) can prevent the building of the next dam, which will impact heavily on the cost of water to consumers. Although it is readily accepted the water in South Africa is too cheap, an uncontrolled price hike will cause tremendous problems for the economy that is already under stress. Apart from the direct saving derived from the curbing of losses and more efficient use of water, substantial indirect capital cost savings can also be achieved.
