Cape Town has been used as a case study for the potential for harvesting stormwater using existing, well-established flood attenuation infrastructure, adapted with nature-based solutions (including green infrastructure / Water Sensitive Design (WSD) options). In Johannesburg, other opportunities for integrating a suite of nature-based solutions that are starting to emerge as a consequence of policy such as the Stormwater Design Manual will be examined. The project will provide important knowledge for a possible future study on upscaling WSD to other cities in South Africa. The PaWS project has just completed. PaWS2 - phase 2 has begun. Some PaWS project outputs are highlighted below, but for a more comprehensive list click here.
The overall objective is to identify opportunities for, and generate knowledge on, the physical and institutional integration of decentralised nature-based solutions into the urban water cycle to support and accelerate a transition towards water resilience in South African cities. The experimental has addressed in two inter-related work package (WP) streams: WP1 on physical experimentation with and evaluation of WSD options at different urban scales; and WP2 on exploring governance processes for enabling the emergent transitions.
