Efficiency is a special need in water systems and technology is a key element to reach it. Enabling technologies like GIS, Network mathematic models, SCADAs, smart metering and saving equipment are implemented at different stages in many urban water supply systems. There is no doubt about their positive contribution to their improvement but this contribution is, very often, very different than the expected when their implementation was decided. A review of theoretical benefits and real difficulties and constraints to use them in efficiency policies in urban water supply systems will be presented .
