In response to growing pressures on available water resources, potable reuse represents a practical source of drinking-water in many circumstances.

This document describes how to apply appropriate management systems to produce safe drinking-water from municipal wastewater. Information is provided on specific aspects of potable reuse, including the quality and protection of source wastewaters, types of control measures, monitoring considerations and public acceptance. Application of potable reuse is also illustrated through a number of case studies.

The guidance is intended for use by drinking-water suppliers and regulators who are familiar with the WHO’s Guidelines for drinking-water quality and, in particular, the framework for safe drinking-water, including water safety plans. This publication may also be useful to others with an interest in potable reuse including environmental health and water resource professionals.
