PROCEEDINGS-ARTICLE 0 Reads 0 Citations Addressing Water Scarcity in South Africa through the Use of LID Published: 11 October 2017

By 2030 the Republic of South Africa (RSA), a developing country, is predicted to be severely impacted by physical water scarcity. 2015 was one of the driest years on record, leaving many towns with extremely compromised water supply systems whilst also limiting food production across the country. This is placing pressure on the already fragile economy. In order to avert a future water crisis, the country needs to reduce its reliance on conventional surface water schemes based on impoundments on rivers. This paper presents an initial assessment of the potential role of low impact development (LID) for the purposes of stormwater harvesting (SWH) and describes the principal outcomes from two RSA case studies. The findings suggest that SWH could substantially increase the supply of water to urban areas, but that there are a number of barriers to its wider use that need to be addressed. The paper concludes with three “position statements” describing how SWH, with the assistance of LID, can contribute to: improving water security and increasing resilience to climate change in urban areas; preventing frequent flooding; and providing various other additional benefits such as amenity and the preservation of biodiversity.

In recent decades South Africa has witnessed a substantial growth in its urban population. This growth has been accompanied by the mushrooming of informal settlements (shantytowns) flanking more formal development. The lack of adequate urban drainage in many of these informal settlements has resulted in extremely polluted environments which add to the disease burden of the poor people who live there. In many instances, informal settlements in South Africa are established on marginal land that is inherently difficult to service using conventional gravity sewerage. International experience has shown that various alternative wastewater collection systems may present more appropriate ways of providing water-borne sewerage in areas that are difficult to service by conventional means. Alternative sewerage schemes have however had a poor record of success in South African informal settlements - primarily stemming from the implementing agencies' failure to adequately address various social and institutional factors. In this paper, a review of South African experiences with simplified sewerage, settled sewerage and vacuum sewerage in urban informal settlements is used to highlight the key constraints that currently impede the application of these technologies.
Article 1 Read 5 Citations Community-focused greywater management in two informal settlements in South Africa Published: 01 June 2009
Water Science and Technology, doi: 10.2166/wst.2009.294
South Africa is struggling to provide services to the millions of poor people migrating to the major centres and living in informal settlements (shanty towns). Whilst the local authorities are generally able to provide potable water from the municipal network to communal taps scattered around the settlements, there is usually inadequate provision of sanitation and little or no provision for the drainage of either stormwater or greywater. This paper describes an investigation into ways of engaging with community structures in the settlements with a view to encouraging "self-help" solutions to greywater management requiring minimal capital investment as an interim "crisis" solution until such time that local and national government is able to provide formal services to everyone. The work was carried out in three settlements encompassing a range of different conditions. Only two are described here. It has become clear that the management of greywater has a low priority amongst the residents of informal settlements. The lack of effective political structures and the breakdown in communication with Ward Councillors and local government officials have contributed to the lack of progress. As the project progressed it became evident that greywater cannot be considered separately from stormwater, sanitation and refuse removal.
