The City Water Resilience Approach (CWRA) helps cities plan and implement actions to build resilient urban water systems. A critical first step in this process is understanding the local water system, and the factors that contribute to or detract from resilience.
This report details research undertaken in Johannesburg with the goals to:
Define the city water basin including natural basin(s), the urban water system and its governance structure, and the interdependencies with other systems
Identify the factors contributing to the resilience of the city water system and those increasing its vulnerability.
In developing this characterisation report, the Arup team collected desktop data on the biophysical characteristics of the basin and key actors in the water system.
