DWA Topics: Non-Potable Water Reuse – Development, Technologies and International Framework Conditions for Agricultural, Urban and Industrial Uses” focuses on reuse of reclaimed water produced from municipal wastewater by centralized or decentralized treatment facilities. This report is intended to provide general guidance for water utilities, consulting engineers and regulatory agencies for planning and expanding non-potable water reuse as an alternative freshwater supply, in particular for agricultural irrigation, urban landscape irrigation and other urban uses, and industrial practices. The report provides an overview regarding relevant regulations and guidelines of water reuse, continues to describe the various aspects of risk management involved in water reuse, and also highlights the various technologies that are applied for water reuse. It does not provide numerical recommendations, which must be derived from site and country specific conditions and assessments. The report is structured into ten chapters, covering the relevance of water reuse, regulations and compliance, development of water reuse projects, health risk management, socio-cultural aspects and public perception, ecological and agricultural aspects, energy requirements, economics, as well as an assessment matrix regarding various treatment processes. An additional compilation of case studies provides valuable experiences.
