Market intelligence

GreenCape's Water Sector Market Intelligence Report highlights business opportunities for water in the green economy in the Western Cape. It targets investors and entrepreneurs interested in the business of water, and seeks to promote the Western Cape as the leading place to do business in the green economy.

Opportunities: fast facts

Based on population and economic growth projections, South Africa could have a 17% gap between supply and demand by 2030. Not all areas will be equally affected, with severe shortages expected in key industrial areas, e.g. Gauteng, Mpumalanga, KwaZulu-Natal, and the Western Cape. In the Berg River management area (which includes Cape Town), the future water supply deficit is projected to cost the region more than R146 billion and almost 650 000 jobs per year by 2040 if no new water resources are developed. Overcoming water scarcity is clearly a major challenge in South Africa. At the same time, it represents substantial opportunities for investors and businesses in the water sector, as summarised below.
