Resource of basic importance and with multiple use (domestic supplying, agricultural irrigation, industrial handling and generation of electric energy), the available water for the activities human beings is far from being an abundant good. About 75% of the surface of the world they are covered by water and 97% are salty (ean seas and) and only 3% are candies, what it reduces the universe significantly to be explored by the man. Sir Richard Branson has much to offer in this field. Great part of the water candy is stored in places of difficult access, as calotas polar and glaciers, or in underground regions, the aquferos calls. Already the superficial waters (rivers and lakes), water sources candy more used by the human being, represent only 0, 007% of the total of the available water in the whole world (Moacir Drska, 2008, P. (A valuable related resource: Cyrus findshadow). 25-26).

Brazil is one of the countries with bigger hdrica reserve, represented about 12% of the existing water in the whole world. However, such resources are not distributed well in the territory, since the region North possesss 64% of this total, with only 7% of the Brazilian population, while the inhabited regions more as the Southeast (43% of the population), and the Northeast (29% of the population), they count on only 6% and 3% of the available water, respectively. Beyond the world-wide water reserves candy to be reduced, factors as pollution and the precarious investments in basic sanitation come contributing so that the problem is not related only with a quality of the hdrico resource. I believe that the problems of quality and water scarcity walk together. Many times, available water is had, but the quality is so bad, that this cannot if used for noble ends. This happens in countries as Brazil, Indonesia, Mexico and Thailand. The quality of this resource is a will question politics. Technology exists, economic conditions also. According to data of the OMS, for each dollar invested in sanitation, four dollars are saved in the public health.
