Methodological note

Methodological aspects

The Catalan Water Agency (ACA) manages and plans the water cycle, with a vision of integrated water systems, taking into account the balance of all ecosystems. Water becomes a basic structural and functional element to the environment and life. This management must be compatible with the growing demand for permanence, universality and immediacy of the citizens of an advanced society, and ensure quality and good service.

The data on water quality shows the controls registered in accordance with the Framework directive on water from the year 2007. For the study of the bathing water for beaches, rivers and lakes, the microbiological quality of the water is measured. For wastewater treatment plants, data is provided on the capacity of treatment, the population served and overall performance.
