GUIDELINES ON WATER SAFETY INVESTMENT PLAN (WSIP) FOR APPLICATION IN IMPLEMENTATION OF WATER SAFETY PLAN PHASE 3 IN VIETNAM
Water supply companies may face challenges when developing an investment plan for implementation of WSPs, due to the relatively large number of objectives with limited available budget for funding. This draft publication aims to provide guidance for water service companies to develop an investment plan that can meet the most of basic requirements of a WSP in a most cost-effective manner.
This draft publication is currently under review, and we would welcome your feedback to WSPortal@iwahq.org.
Global status report on water safety plans: A review of proactive risk assessment and risk management practices to ensure the safety of drinking-water
Based on information gathered from 118 countries representing every region of the globe, this report provides a picture of WSP uptake worldwide. It presents information on WSP implementation and the integration of WSPs into the policy environment. It also explores WSP benefits, challenges and future priorities.
It is envisaged that this report will serve as a useful resource for policy-makers, practitioners and other stakeholders to inform and strengthen the planning and practice of WSP implementation.
Training workbook on Water Safety Planning Urban systems
The objective of this workbook is to serve as a guide to facilitate WSP development for an organised water supply that is managed by a water utility or similar entity. WSPs can be tailored differently for each specific water supply system. This workbook is generic and is not specific to any particular country. It is anticipated that trainers in each country would develop their own WSP training material which would be linked directly to country drinking water standards and implementing guidelines as well as bring written in other appropriate languages.
CLIMATE RESILIENT WATER SAFETY PLAN IMPLEMENTATION – Guidelines for Community Managed Rural Drinking Water Supplies
The purpose of these Ethiopian guidelines is to provide step-by-step guidance to the rural community/board managed water supplies on how to develop, implement, monitor, and review the rural community managed water safety plans aimed at protecting human health. Furthermore, it serves as a practical tool in identifying and addressing priority risks to the water quality and quantity, reliability and sustainability of the rural water supply system including risks related to current and future impacts of climate changes by taking into consideration available resources and capacities of the water supply system.
South Africa The development of a generic water safety plan for small community water supply
This document describes development of a Water Safety Plan with a background focus on Africa.
Development and implementation of water safety plans in Iran
This presentation describes the development and implementation of WSP in Tabriz in Iran under the guidance of the World Health Organization Regional Office.
The development of a generic Water Safety Plan for small community water supply
This case study describes the development of Water Safety Plans in small community water supplies in South Africa. It describes the previous assessment methods as well as the eleven steps taken to develop and implement the WSP.
Das Water-Safety-Plan-Konzept: Ein Handbuch für kleine Wasserversorgungen (The WSP concept: a manual for small water supplies)
The German Environment Agency and the Water Technology Centre published a manual for implementation of the WSP approach in small-scale water supplies in Germany in 2014, which complements the technical rule on WSPs of the German Technical and Scientific Association for Gas and Water (DVGW) with practical explanations, recommendations, examples and supporting tools.
Water quality, compliance, and health outcomes among utilities implementing Water Safety Plans in France and Spain
Water Safety Plans (WSPs), recommended by the World Health Organization since 2004, seek to proactively identify potential risks to drinking water supplies and implement preventive barriers that improve safety. To evaluate the outcomes of WSP application in large drinking water systems in France and Spain, we undertook analysis of water quality and compliance indicators between 2003 and 2015, in conjunction with an observational retrospective cohort study of acute gastroenteritis incidence, before and after WSPs were implemented at five locations. Measured water quality indicators included bacteria (E. coli, fecal streptococci, total coliform, heterotrophic plate count), disinfectants (residual free and total chlorine), disinfection by-products (trihalomethanes, bromate), aluminum, pH, turbidity, and total organic carbon, comprising about 240K manual samples and 1.2M automated sensor readings. We used multiple, Poisson, or Tobit regression models to evaluate water quality before and after the WSP intervention. The compliance assessment analyzed exceedances of regulated, recommended, or operational water quality thresholds using chi-squared or Fisher’s exact tests. Poisson regression was used to examine acute gastroenteritis incidence rates in WSP-affected drinking water service areas relative to a comparison area. Implementation of a WSP generally resulted in unchanged or improved water quality, while compliance improved at most locations. Evidence for reduced acute gastroenteritis incidence following WSP implementation was found at only one of the three locations examined. Outcomes of WSPs should be expected to vary across large water utilities in developed nations, as the intervention itself is adapted to the needs of each location. The approach may translate to diverse water quality, compliance, and health outcomes.

Guidelines for using Web-Enabled Water Safety Plan Tool
The Water Research Commission (WRC) project K5/1993//3 “Web enablement of a water safety plan and incorporation of existing similar supply system assessment tool” aimed to establish a methodology to identify and manage the risks of water services infrastructure and the means by which Water Services Institutions (WSIs) are better able to identify and manage these through use of Water Safety Planning. The tool assists in developing a Water Safety Plan. Implementation thereof (e.g. taking required actions, implementing corrective actions, developing and implementing management and communication procedures) of the Water Safety Plan depends on the Water Services Institution (WSI).
Guidelines for drinking-water quality (4th Ed.) – CHINESE
The Guidelines for drinking-water quality is an authoritative basis for the setting of national regulations and standards for water safety in support of public health. It provides guidance on ways of implementing its recommendations of contextual hazard identification and risk management, including catchment-to-consumer water safety plans.
Guidelines for drinking-water quality (4th Ed. incorporating the first addendum) – ENGLISH
The Guidelines for drinking-water quality is an authoritative basis for the setting of national regulations and standards for water safety in support of public health. It provides guidance on ways of implementing its recommendations of contextual hazard identification and risk management, including catchment-to-consumer water safety plans. The Guidelines position WSPs as a core element of the Framework for Safe Drinking-water and outline the principles and key elements of a WSP for policy-makers.
