Thus, valley to stand out that the Brazilian Amaznia is a set of landscapes and ecologias (Ab' To know, 2005), that it understands well-known expressive biodiversity. Not obstante, the Brazilian Amaznia, so acclaimed for its natural wealth, also exhibits huge sociodiversidade, that if verifies for the occurrence of 180 aboriginal peoples, 357 remaining communities quilombolas and thousand of communities of seringueiros, messengers or babaueiros (Heck and col., 2005). In a generalized manner, Brazil is a privileged country how much to the volume of hdricos resources, therefore it shelters 13.7% of the water candy of the world. However, the availability of these resources is not uniform. More than 73% of the water available candy in the country encontrase in the Amazonian basin that is inhabited by less than 5% of the population. But 27% of the Brazilian hdricos resources are available for the too much regions, where 95% of the population of the country inhabit (Rasp, 1999).
The water availability is not only uniform, but it offers of treated water reflects the contrasts in the development of the Brazilian states. While in Southeastern region 87.5% of domiciles are taken care of by net of water distribution, north-eastern the percentage are of only 58.7% (PNSB 1989, Opas 1998). Brazil also registers high wastefulness: of 20% 60% of the water treated for consumption if lose in the distribution, depending on the conservation conditions of the supplying nets (IBGE, 2002). Beyond these losses of water in the way it enters the stations of treatment and the consumer, wastefulness also is great in our residences, involving, for example, the time necessary to take bath, the proper form as we take bath, the use of discharges in the sanitary vase that consume much water, the laudering of the ware with current water, in the use of the hose as broom in the cleanness of sidewalk, the laudering of cars etc.
