The water distributed by EMATSA favourably exceeds the health criteria established by the competent health authorities as well as those established by the World Health Organization and the European Union, as established in the 140/2003 Royal Decree of 7 February, establishing the health criteria of quality drinking water.

The World Health Organization and the European Union consider drinking water as that which a person can drink every day, for life, without risk to their health. Therefore drinking water is the safest resource in the world. When it reaches households it is totally safe, as it has rigorously exceeded all the controls carried put by health authorities.

Undoubtedly. Tap water is drinkable, in other words, it is water that people can drink without any risks to their health.

To set the quality of tap water, the European Union, following the recommendations of the World Health Organization, determines the boundaries of the presence of certain components in the water. Many of these do not damage the human body, some are indeed beneficial, and others, only if they are present in large quantities.

In order to define the levels for drinking, researchers base the daily intake of a person throughout his life – 2 litres daily for 70 years – with a very high safety margin.

  • The Ministry of Health and Consumption, which is who establishes national regulations – based on European legislation – to establish the maximum concentrations of the substances present in water.
  • The health authorities of the autonomous communities, which monitor the proper disinfection of water and carry out parallel analysis to those established by the water management companies.
  • EMATSA, who is responsible for providing water quality defined by the established law, and to perform all quality controls set by the legislation and report if any anomalies are detected.
  • Each consumer, who holds the responsibility of taking care of drinking water on their property, carrying out, for example, correct maintenance of their indoor installation.

EMATSA continuously performs analysis to detect the presence of undesirable microorganisms and chemicals, and to control other properties such as odour, colour or flavour. It analyses the presence of more than sixty microbiological parameters and chemical types, and tests for other characteristics such as odour, colour and taste.

We also continuously carry out analysis of residual chlorine in drinking water in different parts of the distribution network, to ensure the presence of a low dose of this disinfectant, as an additional health guarantee.

14,000 strains of the water supply a year are tested by EMATSA.

Tap water is safe and meets all the quality standards set by legislation. Therefore there is no need to purchase any additional devices to treat this water. It should also be noted that if these devices are not suitably chosen, nor monitored regularly and recommended maintenance is not carried out, health risks may arise (bacterial contamination, excessive water demineralisation, high concentrations of sodium, etc..).

Drinking water fit for human consumption has salts and substances in its composition that give it a special taste and smell. Therefore, water which has a specific taste and odour must not be considered as an indicator of non-drinkable water. In fact, most of the components that cause the water to have an appearance, taste or unpleasant odour are not harmful to health.

However, should the case arise where suddenly the water is dirty, with an unpleasant taste or odour, we recommend that you contact our customer service.
