  1. Water Demand Management in the City of the Future Water supply and sustainable urban water management

  2. The Urban Water Cycle The SWITCH approach to urban water management: Integration = more sustainable Source: SEQ Healthy Waterways Partnership (http://www.healthwaterways.org)

  3. 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

  4. Water supply and urban development Energy Waste management Parks, gardens and recreation Local economic development Health

  5. 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

  6. Drawbacks of the conventional approach to water supply management • Unsustainable use of local resources • Cost • Carbon emissions • Wasteful use of resources • Non-flexible

  7. Increasing challenges Inadequately designed and maintained infrastructure Increased urbanisation Increasing demand for water Changing weather patterns due to climate change Increasing costs for energy
