Summary

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.

Challenges

The main challenges encountered by the Consórcio PCJ to promote the revitalization of the Ribeirão Quilombo were:

  • Lack of information and planning;
  • Little integration between the various municipalities and agencies in the area of sanitation and environment;
  • Poor water quality and lack of riparian forests;
  • Fundraising to carry out the necessary revitalization actions.

Beneficiaries

  • The entire population of the municipalities of Americana, Nova Odessa, Sumaré, Hortolândia and part of the municipalities of Paulínia and Campinas;
  • Local governments;
  • Water utilities;
  • Fishermen.

How do the building blocks interact?

For the execution of the revitalization actions of Ribeirão Quilombo, initially it was necessary to perform the diagnosis of the Ribeirão Quilombo Basin. From this survey, it was possible to identify the necessary actions that each municipality should take to improve the water quality of Ribeirão Quilombo. After sensitizing the regional community about the importance of revitalizing watercourses through the application of public policies capable of involving managers, command and control entities, community, partners and representatives of municipal governments, which led to the creation of “Ribeirão Quilombo Revitalization Group”, a Pactuation of those involved in the promotion of revitalization actions of Ribeirão Quilombo was signed, indicating the Schedule of Actions to be taken by each of the municipalities to meet the existing demands in the areas of macrodrainage, reforestation, and sanitation.

Impacts

Through the work done, the “Ribeirão Quilombo Revitalization Group” was formed (April 2018), which through agreement between the municipal representatives and members involved has achieved various actions aimed at the recovery of the Ribeirão Quilombo.

Among the actions carried out, we highlight the construction of a macrodrainage reservoir and the elaboration of linear parks in the municipality of Hortolândia. The planting of more than 113,000 tree seedlings along the Ribeirão Quilombo Basin. Investments in the modernization of Quilombo WWTP, which has 100% treatment of collected sewage, in the city of Nova Odessa. The construction of the Boa Vista WWTP (expected completion in April 2020), which will have tertiary treatment technology, becoming a Reuse Water Producing Station (EPAR), in the Municipality of Campinas. The correction of freshwater sewage discharge points in Ribeirão Quilombo (13 points) and the modernization reform of the Carioba WWTP (scheduled for completion in late 2020) in Americana.

The Municipality of Sumaré, one of the most critical in the issue of wastewater treatment, has a TAC (Conduct Adjustment Term) in which the concessionaire of sanitation services in the municipality has committed to raise from 27% to 100% the rate of sewage treatment by 2022. In addition, CETESB installed 3 new water quality monitoring points.
