This document provides guidelines for the management of decentralized water reuse systems and water reuse applications in urban areas.

This document addresses decentralized water reuse systems in their entirety and is applicable to any water reuse systems component (e.g. reclaimed water, source water, treatment, storage, distribution, operation and maintenance, and monitoring).

This document covers:

• management of each system component of a decentralized water reuse system;
• specific aspects for consideration and emergency response.

This document does not cover monitoring parameters and regulatory values of a decentralized water reuse system.
