Unauthorised access to the network

by Bob Breach , 01. August, 2009

It is the experience of many water suppliers that illegal or unauthorised access to the distribution network can occur for a variety of reasons. This poses a number of water quality risks and can also create wider problems related to loss of revenue. This document briefly summarises the water quality risks associated with unauthorised access and how they can be mitigated.

Emergency management plan checklist

by Bob Breach , 01. December, 2008

Preparation of a well documented and up to date emergency management plan is an essential component of an effective incident response framework. The structure and content can only be determined by each water supply taking account of a wide range of different local factors. However this document provides a checklist of those items which need to be considered.

Conducting consumer surveys of water acceptability

by MWH , 01. August, 2009

Communication with consumers is a key part of assessing and promoting the acceptability of drinking water supplies with consumers. The evaluation of consumer acceptability and knowledge of consumer complaints are important components of assessing the overall effectiveness of a WSP and an essential part of the verification of a WSP. This document summarises the main approaches to the collection and analysis of consumer acceptability through surveys.

Comprehensive Framework for integrated risk management in WSP

by Lans Rosen and Andreas Kindhe , 2009

Risk assessment and risk prioritisation are critical elements of a Water Safety Plan. However the process can be complex, require considerable resources and take a long time. Therefore before establishing a risk management system it is important to be clear on the most cost effective approach to meet local priorities and needs. This document provides an overview of the TECHNEAU Generic Framework, which is a comprehensive structure for integrated risk management from catchment to consumer in Water Safety Plans, considering both water quality and water quantity

WSP summary of benefits and costs

by Bob Breach , 01. November, 2008

Before implementation of a WSP it is important to clearly identify the expected benefits and the associated costs both of which could be significant. This will help secure the support of senior management, ensure that sufficient resources are made available and allow much more targeted and efficient implementation. The actual benefits and costs of WSP implementation will vary considerably from utility to utility. This document sets out a summary of the issues that need to be taken into account.

Training workbook on Water Safety Planning Urban systems

by WHO - Western Pacific Region , 01. October, 2008

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.

A guide to conducting household surveys for Water Safety Plans

by US Department of Health and Human Services et al., 02. March, 2008

The aim of this manual is to provide guidance on conducting a household survey as part of a Water Safety Plan for organized piped water supply systems in resource-limited settings. A household survey can help researchers to understand the fate of water from the time it reaches the home to the point of consumption. This survey contributes to Module 2 (System Assessment) of the Water Safety Plan, upon which the subsequent steps of hazard identification, consideration of control measures, and development of corrective actions, monitoring, and verification plans are based. Thus, the survey provides valuable information for the WSP team as the team goes through the process of system evaluation and implementation of changes resulting from the Water Safety Plan. Specific examples intended to guide the planner in designing the survey are provided in the appendices. A summary checklist for survey planning and completion is provided as Appendix A.

Chemical safety of drinking-water: Assessing priorities for risk management

by Therrence Thompson et al., 01. September, 2007

This text provides guidance on the chemical safety of drinking-water. Chemical contaminants of drinking-water are often considered a lower priority than microbial contaminants, because adverse health effects from chemical contaminants are generally associated with long-term exposures, whereas the effects from microbial contaminants are usually immediate. Nonetheless, chemicals in water supplies can cause very serious problems. The objective of this text is to help users at national or local level to establish which chemicals in a particular setting should be given priority in developing strategies for risk management and monitoring of chemicals in drinking-water. The document will be useful to public health authorities, those responsible for setting standards and for surveillance of drinking-water quality, and to water supply agencies responsible for water quality management. In particular, this publication will be applicable in settings where information on actual drinking-water quality is limited, which is the case in many developing countries and in rural areas of some developed countries.
