The Tietê"™s river source is at the county of Salesópolis and his course flows into the country of São Paulo state, characteristic which allowed its utilization as an important path for indigenous, bandeirantes and religious which needed to get to village that grown by his banks. The historic use of the river Tietê indicates since the beginning of XX century, industries used his waters, as such as the need of supplying of São Paulo capital and surroundings that also was growing up.  Nowadays, the demand for his waters is each time bigger and this brings problems related to the guarantee of water quality and availability. The river starts to get loads of pollution at the county of Mogi das Cruzes, about 15 km upstream. Since the decade of 1990, a lot of projects were implemented to river"™s recovery, but, after more of two decades, the achieved results are minimal. Recent data indicates that the pollution spot at the river, part which the water quality is consider bad or terrible, get close to 137 km. The research here introduced seeks contribute as base to disscusions of projects already implemented to Tietê"™s river recovery, as such as evaluate the possible causes to the little achieved results. A comparison with process of urban rivers recovery in another locations will also be done, with the goal of highlighting positive experience and demonstrate that urban rivers recovery is possible and viable and should be seen as priority to society, ensuring that the premises of sustainability be reached.
