The quality of distributed water, maximum contaminant levels, and minimum analysis frequencies have been established within the European Union (Directive EU 2020/2184) and have been transposed into Spanish legislation (Royal Decree 3/2023). Supply systems, like water quality, are closely monitored by supply owners through control and surveillance units (CSUs) and by the Health Department.

Available indicator

Proportion of population using safely managed drinking water services
Target

6.1 By 2030, achieve universal and equitable access to safe and affordable drinking water for all
Goal

6- Ensure availability and sustainable management of water and sanitation for all
Definition

The proportion of the population using safely managed drinking water services is defined as the proportion of population using an improved drinking water source which is accessible on premises, available when needed and free from faecal and priority chemical contamination.

“Improved” drinking water sources include: piped supplies, boreholes and tubewells, protected dug wells, protected springs, rainwater, water kiosks, and packaged and delivered water.
Theoretical formula \[PPC^{t} = \frac{PC^{t}}{P^{t}} \cdot 100\]

where:

$PC^{t} =$ population using safely managed drinking water services in the year $t$

$P{t} =$ population on July 1 of year $t$

This section provides more information about the United Nations indicator or the European Union Sustainable Development Indicator, such as its rationale, international results, metadata, and other relevant statistics.

Rationale

Access to safe drinking water is essential for good health, welfare and productivity and is widely recognized as a human right. Drinking water may be contaminated with human or animal faeces containing pathogens or with chemical and physical contaminants, leading to harmful effects on health.

While improving water quality is critical to prevent the transmission of many diseases (such as diarrhoea which exacerbates malnutrition and remains a leading global cause of child deaths), improving the accessibility and availability of drinking water is equally important for health and welfare, particularly for women and girls who often bear the primary responsibility for collecting drinking water from distant sources.

SDG indicator 6.1.1 is designed to address safe management of drinking water services, including dimensions of accessibility, availability and quality.
