4.14 Reinforcement Learning for Water Management

Scarcity of water and the increasing awareness of the need to save energy in providing good quality water to increasing numbers are driving the search for new ways to save water as well as energy and improve the financials of water utilities. At the same time the increasing “digitalization” of urban Water Distribution Networks (WDNs) is gen-erating huge amounts of data from flow/pressure sensors and smart metering of household consumption and enabling new ways to achieve more efficient operations. Sequential decision models are offering an optimization framework more suitable to capture the value hidden in real time data assets. More recently, a sequential optimisation method based on Approximate Dynamic Programming (ADP) has been pro-posed, whose preliminary computational results demonstrate that this methodology can reduce the electricity expenses while keeping the water pressure in a controlled range and, at the same time, is able to effectively deal with the uncertainty on the water demand.
