Annual Analytical Control Plan

Your water should be quality water


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, and Royal Decree 865/2003, which regulates the health and sanitary criteria for the prevention and control of Legionnaires' disease).

At Aguas de Antigua, we work to guarantee the health, quality and cleanliness of water. To do this, we comply with all legally established safety and hygiene requirements to protect people’s health.

All tests are performed by an external certified laboratory that guarantees the highest standards of reliability in the results. These results are then sent to the Ministry of Health and entered into the National Drinking Water Information System (SINAC).

We also use remotely managed automatic control systems that enable us to continually check and correct water quality indicators: Residual chlorine, pH, conductivity and turbidity.

These automatic controls supplement lab controls, in compliance with the Drinking Water Quality Control Plan, which establishes the health criteria for the quality of drinking water.
