The Council for the Sustainable Use of Water (CUSA) is the advisory body of the Catalan Water Agency (ACA) and participates in creating water planning instruments. 

Council members hail from local administrations, environmental institutions, agricultural and livestock institutions, academics, recreational institutions, industrial institutions and neighbourhood associations.

This forum is for discussing how to develop new water basin management planning policies together with the water distribution committees. Their assessment, opinions and comments are used by the Government in water planning decision-making.
