ITA (before Instituto Tecnológico del Agua) is an Universidad Politecnica de Valencia research group. Our activity is focused on research and development dealing with urban water engineering and management. The ITA is formed by a group of water professionals consolidated over the last thirty years in Valencia and which originated around the Fluid Mechanics Chair at the UPV. Problems and concerns connected with water are developing at great speed in our society. The sustainable management of water is now taking the foreground in many parts of the world, a tendency which will only accentuate in the future. New concepts and new tools are needed to enable proper sustainable management of urban water, which is why the efforts of ITA focus on efficiency and sustainability, incorporating the the technical background which our work has always had.
