Water quality control

Control calidad del agua Hidraqua (bloque 1)

Your water should be quality water

Water quality control is our main goal


We have developed an Annual Analytical Control Plan in conjunction with the health authorities, which establishes test frequency and parameters for controls, ensuring at all times full compliance with regulations (Royal Decree 140/2003, regulating health criteria for the quality of water for human consumption, Royal Decree 314/2016, which incorporates basic criteria for health protection against hazards derived from ionising radiation in water for human consumption, and Royal Decree 902/2018, amending Royal Decree 140/2003, and Decree 58/2006, implementing Royal Decree 140/2003).

These results are then sent to the Ministry of Health and entered into the National Drinking Water Information System (SINAC), where members of the public can consult the classification of their town’s water supply.

To establish drinkability levels, researchers use as a daily consumption benchmark of someone drinking an average of two litres of tap water a day for 70 years, with very generous safety margins.

Drinking water is one of the world's most controlled resources. We have automatic control systems that provide continuous remote control over water quality indicators, such as residual chlorine, conductivity, turbidity, pH and temperature.

At Hidraqua, we carry out lab controls in compliance with the Drinking Water Quality Control Plan, which establishes the health criteria for the quality of drinking water.
