Drinking water

A drinking water safety plan is a proactive method of assessing risk to drinking water quality, which better protects public health. Plans are based on an assessment of risk factors that could potentially adversely affect drinking water quality. Assessments consider such things as:

  • The source of the water;
  • How drinking water is treated; and
  • How treated water is stored and distributed.

These plans do not replace the Guidelines for Canadian Drinking Water Quality or the drinking water monitoring and reporting requirements under the Environmental Protection and Enhancement Act. Rather, drinking water safety plans are meant to complement and enhance drinking water quality standards and procedures. An effective drinking water safety plan is dependent on four principals:

  • Collecting and evaluating the best information available about the water supply system
  • Analyzing and understanding potential risks
  • Correctly assessing risk mitigation – how to reduce risks to an acceptable level
  • Determining what resources and actions are necessary to ensure identified risks are reduced
