The scarcity of water resources is a concern that currently rages across the globe, including countries that have historically abundant water sources, such as Brazil. The International Water Association (IWA) announces long the water balance (BH) as one of the main tools to control and reduce losses of water distribution systems. In search of efficiency of water use, the sanitation sector can contribute to the awareness and consumption of control acting on the real and apparent losses in order to act on the demand and do not need to increase investment, increasing in the pursuit of expansion of supply.The CAGECE, Water and Sewage Company of Ceará, has been undergoing upgrades and innovations to continue to maintain a competitive and updated company, aiming at the continuous search for the execution of their mission. It has in its policy commitment to the public water supply the best possible way, from the continual refinement of techniques and methods used. Although the final master plan for the metropolitan region of Fortaleza has recently been completed, the suggested actions in relation to the same loss control are in the design phase. The main action will be the division of the integrated system of 121 districts in the metropolitan area monitoring and control (DMCs), which undoubtedly will facilitate the operational management and will bring a significant reduction of losses. It will be easier to identify the root causes, in addition to support the management of pressures for each system independently. For managing loss from this kind of actions, Cagece has developed its own software, called Siscope. The Siscope aimed the improving of the operational management and consequent reduction of energy consumption and water losses. Monitoring through the water balance with a high level of detail allowed the operational optimization in relation to supply, as well as subsidizing actions to mitigate losses in supply systems. Information was provided transparently to the users in a database, facilitating and enabling the use of updated information at any time, via the intranet. It presented a technical description of a system that allows the use of operational management information in an integrated and focused on a broad, strategic analysis of key indicators related to loss control.
