applied independently of other management system standards or integrated with

integrates the principles of the HACCP system and application steps developed by
the Codex Alimentarius Commission. Perhaps this is the standard to which water

6.3.2 The World Health Organization Water Safety Plan

The use of HACCP for water safety was proposed by Havelaar ( 1994 ), and Iceland
appears to be the first country to adopt the idea. The HACCP was also the basis for

the Water Safety Plan (WSP) in the third edition of the World Health Organization
(WHO) Guidelines for Drinking-water Quality, (2004), which has been described
as n

et al. 2008 ). The WHO HACCP-based framework, in particular the WSP, has been
successfully applied to assessing and managing the risks posed by Legionella in
building water systems (Bartram 2007 ). The WHO makes available both a Manual
and an Excel-based management tool, which are available for use and can be
downloaded from the WHO website (WHO 2004 ).
The template for a WHO-style Water Safety Plan emphasizes awareness of
hazards of land use in general, and community education and outreach for water
safety. This is particularly bene

“ a way of adapting the HACCP approach to drinking water systems ” (Ros é

cial for developing countries where community
education can do much to improve drinking water safety. There is also a simpli ed

version for preparing a Water Safety Plan for Small Communities (WHO 2012 ).
Water Safety Plans have three major top-level components, which are then
broken down into subcomponents. The three top-level components are:

2 International Organization for Standardization (ISO) is a worldwide network of national stan-
dards bodies from over 160 countries, which was established in 1947. The mission of ISO is to
develop International Standards (i.e. ISO 9001, ISO 14000, ISO 27000, ISO 22000), and to make
sure that goods, services, as well as processes are safe, reliable, and of good quality. As the
management system standard, ISO 9001:2008 sets out the criteria for a quality management
system implemented by over one million companies and organizations. To ensure that food is safe,
ISO 22000:2005 contains the overall guidelines for food safety management, helping to identify
and control food safety hazards. Detailed information can be found from http://www.iso.org/iso/
