Therefore, the water utility hired of the Guarulhos Partnership HAGAPLAN-SANEAR to analyze the water supply system and propose a plan to reduce water losses. Within this contract to provide services, from HAGAPLAN we are starting to implement the method defined in this paper. The aim will be to implement all the steps described above, i.e., focusing the strategic actions to reduce water losses and the organization of the water utility in the customer requirements and goals (Partnership HAGAPLAN-SANEAR, 2012). However the success of strategic actions defined in this methodology (Fig. 5) is related to actions at the tactical level defined in the methodology proposed by Souza et al (2009), which was summarized in Fig. 4.
