The Ribeirão Quilombo River basin encompasses six important municipalities that house approximately 2,072,000 inhabitants, namely: Americana, Nova Odessa, Sumaré, Hortolândia and part of the municipalities of Paulínia and Campinas. The Ribeirão Quilombo presents highly polluted waters due to domestic and industrial sewage discharges, not being indicated for urban use and requiring actions for its depollution.
The recovery of water and floodplain protection areas of the Ribeirão Quilombo was accomplished through the implementation of the Revitalization Group, through macrodrainage, forest recovery, sanitation quality, and significant regional mobilization in defense of the theme, with the adhesion of the local community, municipalities and entities.
In two years of operation, several structural and non-structural actions were performed, contributing to the recovery of the Ribeirão Quilombo and its environmental protection areas.
