Managing Sustainable Urban Water Reuse: Structural Context and Cultures of Trust

摘要

Water scarcity in urban environments is an issue of increasing concern in Australia and many other parts of the world. Technological solutions include recycling municipal effluent, which can be treated to a standard suitable for nonpotable uses such as garden watering and toilet flushing. Successful operation of such solutions requires institutional arrangements for long-term management, as well as public awareness and cooperation to establish safe practices. This article reports on research undertaken at four case study sites in Australia and the United States and identifies the social and management issues important to the success of water reuse projects. The cross-national findings demonstrate that best practice in residential water reuse technology should be coupled with institutional and structural arrangements that inform and involve the public and provide transparent governance. It is suggested that this combination of technical and social structural elements will facilitate a sustained trust in, and acceptance of, water reuse.
