This book documents innovative approaches for integrating green technologies and decentralized water infrastructure. The two major components of green decentralized water infrastructure are: (1) using locally available alternative water sources (rainwater, greywater, and brackish/saltwater) (at multiple scales, e.g., a single building to a neighborhood community level)

and (2) using renewable energy resources (solar, wind, biomass, geothermal, other). Chapter 1, introduces the concept and framework of green decentralized water infrastructure. The subsequent nine chapters give a detailed description of global case studies, and discuss significant components of the green decentralized water infrastructure and the  challenges. The chapters document global case studies and prospects (chapters 1-7) followed by challenges facing decentralized water infrastructure (chapters 8-10). The book will provide a cross-disciplinary knowledge-base for smart & futuristic water management in urban settings and a significant opportunity for sharing smart and decentralized water technologies at the global level
