Drinking water, wastewater and stormwater systems and services — Guidelines for the provision of alternative water service for essential facilities during a crisis

This document provides guidelines for alternative water service (AWS) provision during a crisis for the ongoing operation of essential facilities. This document addresses: — AWS principles and methods; — AWS operational planning and implementation. This document is not applicable to: — planned water supply interruptions forming part of the drinking water utility's normal operations; NOTE However, many of the principles and methods described can be appropriate in such circumstances. — water supplied to temporary settlements, such as refugee camps; — the development and implementation of a crisis management system for water service, which is covered by ISO 24518[1] and ISO/TS 24520,[2] or the development and implementation of AWS provision during a crisis for private users, which is covered by ISO 24527.[3]
