Water for human consumption

The fact sheet "Water for human consumption" assesses the quality of water at the consumer's tap and identifies its origin.
Description: 

The quality of the water used for human consumption is a key indicator for assessing the development level of a country and the well-being of its population.

In order to ensure this quality, the competent authorities periodically collect water samples to verify its compliance with various chemical, physical and microbiological parameters. Both the number of analyses and the reference values of the various parameters are set out in the applicable legislation – Decree-Law no. 306/2007.

This fact sheet concerns mainland Portugal and shall be updated annually.

Objectives and targets: 

The strategy for the water supply and wastewater treatment sector, embodied in the Strategic Water Supply and Wastewater Sanitation Plan 2020 (PENSAAR 2020), sets the goal of 99% safe water by 2020.

Progress analysis:

The quality of the water for human consumption has shown steady and sustained improvement year after year, achieving, in 2017, a percentage of 98.72% safe water at the consumer's tap (an indicator of controlled, good-quality water), which, within an increasingly demanding regulatory framework, represents an effective improvement in water quality in recent years. Only in the supply areas with less than 500 inhabitants hasn’t the 99% target for the safe water, yet been reached.
