The operation of water supply systems is normally done by professionals who use their experience as the sole source of knowledge in order to establish rules to control the daily operation of hydro-mechanical equipments aiming at the guarantee of an adequate performance of the system. In general, these rules have as main goal the assurance of the water demands of the population and do not take into account optimization of the electrical energy consumed by the pumps. This work proposes a new hybrid genetic algorithm. The main purpose of this code is to determine optimized system operational rules with regard to saving electrical energy consumed by the pumps. The code was tested using one real water supply system localized in Ourém city (Portugal). The results showed considerable decrease in computational time as comparing to other codes available.
