Strategies towards sustainable use of water
• Increasing water supply:
Rivers, lakes and dams in South Africa
o Government strategies – dams, desalination, recycling, • South Africa is a dry country – 460 mm annual rainfall.
controlling leaks and using groundwater. • Rainfall doesn’t spread evenly and there are dry years

Physical factors
The role of government initiatives • Rainfall is unevenly distributed.
• Alien vegetation consumes more water.
towards securing water • Climate change increases temperatures and evaporation.
• South African governments spent millions on over
500 dams - provide water and prevent floods.
• The Katse Dam on the Senqu River in Lesotho The challenges of providing free basic water
increased water in the Vaal River.
• 5-year project to provide free basic water services to the poor.
• Aims to provide households with 6 000 litres of free water monthly.
• Challenges – expense, municipalities, high cost to consumers,
household size and non-payment.
