In 2004, the WHO Guidelines for Drinking Water Quality recommended that water suppliers develop and implement “Water Safety Plans” (WSPs) in order to systematically assess and manage risks. Since this time, governments and regulators, water suppliers and practitioners have increasingly embraced this approach, but they have also requested further guidance. This WSP manual answers this call by describing how to develop and implement a WSP in clear and practical terms. Stepwise advice is provided through 11 learning modules, each representing a key step in the WSP development and implementation process.
