We are Cetaqua.
The Water
Technology Centre

A unique model of public-private collaboration that anticipates the needs of our communities and proposes new R&D&I solutions to ensure the sustainability and efficiency of the water cycle.

Cetaqua centres

Our ecosystem is made up of 4 independent entities that follow the same structure, using a common strategy and working in partnership.

Lines of research

We work on 5 lines of research. Through these lines of research, we identify challenges that can be solved in a way that helps our communities, the environment, and different productive sectors.
