Water Sensitive Urban Design (WSUD) for South Africa: Framework and guidelines
Expanded Title:South Africa (RSA) is a water scarce country challenged with transforming its unsustainably resource-intensive economy whilst also addressing the legacy of Apartheid . The adequate provision of water to RSA’s citizens is one of the most significant challenges facing the countryThis is particularly relevant in the rapidly-urbanising areas owing to the fact that they are hubs of economic growth, and could without proper management become major drivers for increased water demand. It is evident that alternative, systems-based approaches to conventional water management of water supply and modes of ensuring water quality are required. A systems approach with multiple objectives is called for; one that takes into account community values and aspirations when dealing with water supply, wet and dry sanitation, biological and chemical treatment of associated contaminants, drainage and the management of industrial effluents, whilst also acknowledging the range of users, including: residential, institutional, commercial and industrial. An integrated systems-based approach such as this has the potential to facilitate a change in urban areas, from ‘water-wasteful’ to ‘water-sensitive’ settlements, where a ‘settlement’ is to be broadly understood as comprising a concentration of people within a specific area and serviced by some public infrastructure and services. This study was thus aimed at providing strategic guidance to urban water management decision-makers (primarily city managers and other local authority officials) on the use of WSUD in a South African context. It introduces the philosophy of WSUD – a new paradigm in urban water management – and starts to build the case for its adoption in a water scarce country such as RSA, as well as providing a base for future studies. It is aimed at defining what ‘water sensitivity’ might mean within the RSA context – including expanding the definition of ‘city’ in WSC to include a broader range of settlement types – so as to motivate for adopting a context-specific vision for water sensitivity. In this regard it suggests a strategic framework with four different components to enable the transformation to Water Sensitive Settlements (WSS) in RSA, and provides guidance on the various WSUD strategies that could be adopted to achieve this, as well as giving an indication of appropriate modelling tools. A policy review (including institutional and legal issues) was also carried out in order to identify obstacles to WSUD and to provide recommendations on how they may be overcome.
