Water demand is reduced significantly by greywater harvesting (GwH) used for toilet flushing; household water use is reduced by approximately one-third. Savings are made from the reduction in water supplied by delivery tankers, on water infrastructure, from environmental benefits and reduction in health costs, demonstrating that benefits outweigh the costs of the system. This chapter provides insights and observations about GwH, from sources of greywater to types of systems, including issues due to uncertainty and reliability of its use. It describes two case studies (Whichelo Place and Earthship, in Brighton, United Kingdom (UK)) in which GwH has been successfully used, the discussion of which leads into considerations of the future of this approach to meeting increasing water demand. The chapter also critically assesses the future of GwH.
