Reducing Energy for Urban Water and Wastewater: Prospects for China

Can cities reduce the amount of energy used to supply water and treat wastewater? Can this be achieved by one of the largest providers of urban water and sanitation services in the world – China? In Reducing Energy for Urban Water and Wastewater: Prospects for China, these questions are answered to show how cities can cut costs and reduce greenhouse gas emissions. First, the book guides the reader through water supply and wastewater treatment and explains how energy is used at each step. Then, the authors:

• Outline the most effective ideas for reducing energy use in cities, using China as a case study.
• Provide a decision-making framework to help cities focus their efforts.
• Investigate an often-overlooked high energy user in dense cities and suggest a way to cut energy.
• Assess the unintended downside of stricter wastewater standards and how to optimise the upside.
• Provide suggestions for increasing water and energy recovery in water-scarce cities.

The focus throughout is China, the biggest greenhouse gas emitter in the world.
