In Sao Paulo, the State Law for the Water Source Protection (LPM) nº 898/1975, followed by Law nº 1,172/1976, set out the watersheds that should be protected to ensure the production of water. The context for this legislation's formulation was one of intense population growth in the metropolitan region of Sao Paulo (RMSP), which increased the demand for water and pollution input in dams due to non-full sewage treatment. With the advance of metropolitan horizontal and population growth, the main goal of LPM was to protect water sources and supply dams water by controlling the use and occupation of land located in the watersheds, through the establishment of urban parameters that were more restrictive the nearer they were from the dams. Thus, the aim was controlling population and building density in the occupation in the watersheds. At the same time, there were the opening of irregular settlements and occupations by slums, which were more intense from the late 80s to the 90s at Guarapiranga and Billings watersheds, as a result of insufficient housing provision by the State, economic crisis, unemployment increase and family income more compromised with the rent (whether in tenements or slums). This scenario made the popular allotment an alternative to access to housing. In this way, the law intended to implement an abstract model over a real dynamics of land occupation.
