Technology, research, innovation and management models allow us to propose solutions that guide all the processes in the water cycle toward a circular economy. Cetaqua (Water Technology Centre) is a model of public-private collaboration created in 2007 to ensure the sustainability and efficiency of the water cycle, considering local needs. This model is consolidated as a reference in the application of academic knowledge to water and environment, creating products and services that benefit society. Cetaqua focuses in the following research programmes: • Water resources, production and reclamation • Environment, society and economics • Water 4.0, solutions for digital transformation • Wastewater and reuse of byproducts • Quality, safety and health • Networks and infrastructures #Research #Collaboration #ThinkingForward
