Cape Town city council has given its backing to a plan by researchers Pierre Mukheibir and Gina Ziervogel from the University of Cape Town (UCT), which recommends the introduction of tax rebates and other incentives for the installation of rainwater storage tanks, low-flush toilets and systems for recycling effluent, among other things. A study on climate change in South Africa, carried out in the late 1990s, forecast changing rainfall patterns and rising temperatures in the Cape Town region. The city has had to ration water for several summers already.
