Water supply and the urban water cycle Stormwater • Water quality • Potential resource • Sewer capacities • Water treatment standards The Urban Water Cycle Water supply Wastewater • Potential resource • Wastewater volume
Water supply and urban development Energy Waste management Parks, gardens and recreation Local economic development Health
Conventional approach to water supply management • Increased abstractions from rivers and aquifers • The construction of storage reservoirs • The transfer of water from areas with a surplus • The use of energy and chemicals for water treatment
Drawbacks of the conventional approach to water supply management • Unsustainable use of local resources • Cost • Carbon emissions • Wasteful use of resources • Non-flexible
Increasing challenges Inadequately designed and maintained infrastructure Increased urbanisation Increasing demand for water Changing weather patterns due to climate change Increasing costs for energy
