This document provides guidelines for the planning and design of centralized water reuse systems and water reuse applications in urban areas. This document is applicable to practitioners and authorities who intend to implement principles and decisions on centralized water reuse in a safe, reliable and sustainable manner. This document addresses centralized water reuse systems in their entirety and is applicable to any water reclamation system component (e.g. source water, treatment, storage, distribution, operation and maintenance and monitoring). This document provides: Design parameters and regulatory values of a centralized water reuse system are out of the scope of this document.
