Cetaqua

Cetaqua, the Water Technology Centre, is an applied research and innovation organization focused on making the water cycle more efficient and sustainable. Its public-private collaboration model brings together a network of independent centres in Barcelona, Andalusia and Galicia, which share a strategy and work jointly to anticipate societal needs. Cetaqua develops and transfers research, development and innovation into practical solutions for businesses, public administrations and water operators.

Its work spans water-resource planning and management, new water production and resource recovery, zero waste and decarbonization, territorial and social sustainability, and digital services, including artificial intelligence. Projects address challenges such as predicting water availability and demand, detecting unusual behaviour in supply networks, reusing water, recovering valuable materials from wastewater, and producing biomethane from treatment sludge. Cetaqua also helps water operators transform wastewater treatment plants into resource-recovery facilities, supports productive sectors in improving water quality and treatment efficiency, and provides administrations with circularity assessments and ecological transition plans.
