Category Water and Sanitation
KPI Name Drinking Water Quality
KPI No. EN: EN: WS: 1C Type: Core Type: Sustainable

Definition / Percentage of households covered by an audited Water Safety Plan
Description

Rationale / Water safety and quality are fundamental to human development and well-being.
Interpretation / Providing access to safe water is one of the most effective instruments in promoting
Benchmarking health and reducing poverty.
WHO produces international norms on water quality and human health in the form
of guidelines that are used as the basis for regulation and standard setting
worldwide.
The Guidelines for drinking water quality (GDWQ) promote the protection of public
health by advocating for the development of locally relevant standards and
regulations (health-based targets), adoption of preventive risk management
approaches covering catchment to consumer (Water Safety Plans) and independent
surveillance to ensure that Water Safety Plans are being implemented and effective
and that national standards are being met.
Cities should measure the quality of drinking water against the most recent WHO
Guidelines for Drinking Water Quality Fourth Edition.
An improving trend and higher values are considered positive.
