A systematic literature review of the enabling environment elements to improve implementation of water safety plans in high-income countries
Effective risk management helps ensure safe drinking water and protect public health. Even in high-income countries, risk management sometimes fails and waterborne disease, including outbreaks, occur. To help reduce waterborne disease, the WHO Guidelines for Drinking Water Quality recommend water safety plans (WSPs), a systematic preventive risk management strategy applied from catchment to ...

Extending the water safety plan concept to the urban water cycle
The urban water cycle (UWC) is often managed by several stakeholders dealing with specific components of the cycle such as water supply, wastewater systems and water bodies management. Therefore, risk management in the UWC benefits from an integrated approach to incorporate the interdependencies between elements. The water cycle safety plan (WCSP) provides a common risk management framework for ...

Supporting the Water Safety Plan (WSP) approach with the Failure Experience Improvement System (FEIS)
The Water Safety Plan (WSP) aims to ensure safe drinking water through risk assessment and preventive risk management which cover all steps of the water supply from catchment to the consumer. This approach requires a comprehensive hazard assessment including the identification and prioritisation of potential hazardous events. The Failure Experience Improvement System (FEIS) supports this key step ...
