Urban population growth, economic development and change of consumption patterns increase water demand. The challenge is how can water utilities continue using old water infrastructure to maintain the increase of water demand at lower cost? Daily urban water consumption is processed by algorithms to predict the exact needed water amount that should be supplied to the right underground reservoir and at the right time. This water supply via pumps consumes electricity which makes 30-40% of the total tap water cost. Electricity price in Europe and abroad changes every hour of the day for 24 hours. Processing all these data to reduce the water supply cost by more than 3% is one of SCUBIC achievements. Bruno Abreu, co-founder of SCUBIC, discusses in this episode how his platform deploys mathematical algorithms that benefit water utilities making intelligent decisions to cut the water supply cost and reduce the overuse of water infrastructure.
