Integrated passive, traditional and advanced treatment and storage methods to meet changes in recycled water demand: an overview of innovative schemes in southern Australia

Urbanisation, limited water supplies, extremes in weather patterns and environmental disasters demonstrate the need for more robust and flexible water management strategies which encompass recycling. Water reuse schemes have been successfully implemented in agriculture, domestic dual-reticulation, industrial and municipal uses in southern Australia. In each case, the recycling process is adapted to suit the end use, regulatory water quality requirements and changes in seasonal and or annual demand as a result of growth or as recycling becomes more widely accepted within the community. This paper will consider source water quality and quantity, the integration of advanced and passive treatment technologies, storage and demand management. An overview of innovative schemes and trials encompassing stormwater and wastewater will be presented including the Bolivar, Christies and Glenelg Wastewater Treatment Plants.
