Division in sectors technique applied to hydric supplying systems

摘要

The decrease of the hydric losses with the reduction of the operation pressures of the distribution nets is a phenomenon a long time known for the sanitation and water distribution companies. Among the used techniques for this purpose, the division in sectors technique comes, now, as one of the more effective instruments of improvement and optimization of the supplying services. The wide diffusion of this technique, however, would not be possible without the technological evolution of the key elements, necessary to carry out this control method of urban hydric supplying. In this work are presented solutions implemented by the Basic Sanitation Company of the State of Sao Paulo which has been carried out for more than five years. This time allowed that the techniques and the methods presented reach the necessary maturation degree so that a functional and each more reliable model of the division in sectors technique would be established.
