This book addresses the challenge of rapid growth in the water and associated energy demand of cities. Australian cities are used to quantify how water in cities accounts for 8% of Australia's greenhouse gas emissions and 9% of total Australian primary energy use. Residential water use, largely for heating water, comprises 45% of the effect. Urban metabolism theory is developed and used in mass balance analysis to derive quantitative performance indicators for the management of urban hydrology. Priority areas for management and policy formulation are articulated. The thesis provides a new...
