We ensure the quality of your water

Water quality control is our main goal


We have developed an Annual Analytical Control Plan which, together with the health authorities, establishes the frequency and test parameters for controls, ensuring at all times full compliance with decrees (such as Royal Decree 140/2003) regulating the health criteria for the quality of water for human consumption.

In Aquara we work to guarantee the health, quality and cleanliness of the town. To do this, we comply with all legally established health 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 its results. These results are then sent to the Ministry of Health and entered into the National Drinking Water Information (SINAC).
