Why should you use ISO 24527?  

Drinking water is fundamental to life and its distribution is an essential service. Drinking water supply relies on systems that can be subject to disruption from internal or external factors including operational error, lack of rehabilitation, damage to the drinking water system, malicious acts (e.g., vandalism, criminality, or terrorism) and natural disasters (e.g., earthquakes, floods, hurricanes, or volcanic eruptions). 

ISO 24527 provides you with guidelines for the effective implementation of alternative drinking water service (ADWS) provision during extended periods of disruption to the drinking water supply. 

ISO 24527 helps you to reduce the impact on public and personal health and wellbeing, and economic performance due to water interruption.
