Drinking water safety plans are described by the World Health Organisations as follows :-
“The most effective way means of consistently ensuring the safety of a drinking water supply is through the use of a comprehensive risk assessment and risk management approach that encompasses all steps in water supply from catchment to consumer.”

Drinking Water Inspectorate Risk Management Assessment Scheme
The Scheme, launched on 01 August 2019, has been jointly developed by the Inspectorate, Lloyd’s Register and in consultation with water companies.
The purpose of the Scheme is to verify that the risk based drinking water safety plan process (WSP), as advocated by the World Health Organisation, has been implemented, and is consistent with the requirements of the Water Industry Specification document (WIS) (WIS 04-01-04), together with the BSI standard for Security of Drinking Water Supply – Guidelines for Risk and Crisis Management – BS EN 15975-2, and the Guidance document to the Scheme.
