The Impact of Climate Change on Water Services Delivery – A case study of Ekurhuleni Metropolitan Municipality
Expanded Title:Water services management is likely to be one of South Africa’s most complex problems for municipalities in the future. There is a strong link between water services and climate variability around the country. Trends towards greater urbanisation and densification, coupled with environmental changes such as climate change are likely to exert pressure on water resources. It is necessary for strategic planning at a local government level to avoid water supply challenges in the future. The risk that climate change poses to water supply and demand is growing both globally and locally. Incorporating climate change projections and their implications into municipal management is gaining support in cities around the world (e.g. London, New York). Projected climate change is important for various planning horizons, particularly those that aim to address climate and development issues in the short and longer term. Improving the understanding of current storm risks is not purely for the benefit of the science-policy dialogue, but for the affected communities. Efforts also need to be made to understand how flood risk is framed and perceived by those most affected by such storms. The purpose of this study was to evaluate the impact that climate change is likely to have on water services management for a local authority in South Africa by modelling future climate scenarios for South and southern Africa; identifying the risks associated with the expected consequences of the predicted changes in climate and evaluating the impact on water management using a hydrological model. The key findings emanating from this study indicate that Municipalities will have to deal with more frequent high intensity short duration storms. This is going to put huge pressure on existing drainage infrastructure such as storm water and sewerage systems, but will also have an impact on associated infrastructure such as road, buildings etc. Low lying low income settlements were identified to be the most vulnerable and proper planning and intervention is required now to avert any future crisis.
