The use irrational of the water in such a way transforms the supplying residential as industrial into one of the great world-wide problems. ' ' In last the 50 years, the water consumption in the world more than tripled. Today, the people on average consume 800 cubical meters of water per year, 50% more than what 45 years atrs' '. (BARROS, Raphael et al. 1995). In this dimension, this article has as main target to develop a study on mazelas that experience the system of hdricos resources e, to disponibilizar indispensable subsidies to the operational, tactical and strategical planning.
In this manner, to develop efficient and efficient methods and techniques that come to benefit and to solve sustainable the profile to salutar human, and its necessities that them are basic to the survival. Thus, the amount of water consumed for a population can vary in until an order of magnitude, depending on its availability. As (Drangert & Lunguist, 1990, P. 71-86), ' ' the water supply of good quality in the supplying source has little impact on the health conditions if the way of collection and transport will be manual or inadequado' '. Moreover, the object of study of the support of the water is the awareness of the human being in sight its social, economic and ambient responsibility, delimited in a mere indispensable alternative to the survival and the nature surround that them. On the other hand we would not have life much less quality of life, therefore the water is a crucial element to all the existing species of life in our region, parents and planet. Except this, we would be only the hidding place of the inexistent one. For this optics, when thinking about this subject of extreme complexity ' ' Without water it does not have sustentabilidade' ' , it is to imagine in the importance and utility of the water in its broad context, if worrying about the scarcity that already reaches some countries, the example of Egypt, Israel, Saudi Arabia, Holland and Singapura.
