Water quality control


Annual Analytical Control Plan

Your water should be quality water


Tests are carried out to guarantee the absence of micro-organisms and unwanted chemical products and to determine the physicochemical and organoleptic qualities of the distributed water. This involves testing over 100 microbiological, chemical and physical parameters. All these parameters are tested systematically by an accredited laboratory, in accordance with legal requirements and standard ISO 17025.

Aguas de Murcia carries out over 222.000 tests a year on water for human consumption.

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).


Test parameters

Distribution network control test

To determine the physicochemical, organoleptic and microbiological characteristics of the water.

Complete analysis of the network and tanks

To determine the organoleptic, physicochemical, metal, trihalomethane, pesticide, polycyclic aromatic hydrocarbon and microbiological content.

Radioactivity analysisd

In accordance with the latest modification, Royal Decree 140 establishes that potential radioactivity in drinking water must be tested.

DWTP testing

At our DWTP, La Contraparada, we carry out over 120,000 tests a year at all stages of the process, thereby guaranteeing they are all working perfectly.

Legionella testing

The health authorities in the Region of Murcia also require testing of drinking water for Legionnaires' disease, after the epidemic in 2001.

Control Calidad del agua final


The water reaching your homes via the supply network undergoes the strictest controls. Royal Decree 140/2003 establishes which controls have to be carried out. These are divided into three levels:

  • Aguas de Murcia conducts its own controls. Tests carried out in drinking water treatment plants, tanks and the distribution network.
  • Murcia City Council carries out tests on consumers’ taps through its municipal laboratory. Tests in homes and public buildings.
  • The Autonomous Community is responsible for health surveillance. Inspection, test and supervision programmes for the previous two controls.

Further guarantees are provided by the fact that, in the Region of Murcia, most of the drinking water is treated by the Canales del Taibilla Municipal Association and distributed to a numerous towns, who then carry out their own tests. In other words, a large number of towns and organisations all test the same water.

There are over 100 continuous analysers operating 24 hours a day to test the drinking water for turbidity, temperature, pH, conductivity and, above all, free chlorine at different points in the distribution network.

Quality analysis for water supplied

Murcia water representative test results for last month and the water quality analyses are available.
