Synopsis: Ensuring water sustainability can no longer be dealt with in silos. Greater urbanisation exerts pressure on water demand and water security. At the same time, urban and industrial development have rendered many previously permeable surfaces impervious. This results in high surface runoff during storms; and can lead to polluted surface runoff and reduction in deep infiltration. All these come at a time of more frequent droughts and more intense rainfall due to climate change.
Water utility leaders and city planners need to relook the way they manage water in the urban context to ensure water sustainability. Water needs to be managed effectively across the entire water loop from the moment rain falls on the surface to water catchment to water treatment, supply and distribution, and finally to wastewater collection and treatment. Actions in one part of the loop will impact another. Cities in Australia, China, India, the UK and the USA are recognising this. Showcases from China and Saudi Arabia will demonstrate how to implement an approach to take on the entire water loop.
