The world population has becoming an urban society. The concentration of people in cities contributes to increase the demand on public services, especially on the water supply systems. Thus it is imperative that these systems are able to meet this growing supply of drinking water with lower operating costs. Requiring the supply companies, as well as expansion of these systems, the proper operation and efficient. In this work, a model for multi-objective optimization of the operation of the water distribution system was developed in order to achieve efficiency hydropower. Three objectives were considered: (i) reduction of real losses, (ii) reduction of the cost of electricity, and (iii) maximizing system reliability. The optimization model was designed for the construction of an interface between a hydraulic simulator and algorithms NSGAII and SPEA. The model system was applied to a hypothetical water distribution and it was proved to be suitable to generate an optimal set of operating rules. The use of multi-objective optimization model is recommend to promote the efficiency of hydropower water distribution systems existing in both macro and micro distribution.
