Sabesp TIETÊ PROJECT Sabesp accounted for 37% of the sanitation investments made by brazilian state companies, from 2011 to 2014. The Tietê Project is the largest environmental Program in Brazil. In 1992, when the project was implemented, 70% of sewage was collected, and 24% was treated and the pollution reached an extension of 530 km (50% of the length of the river). In 2015 – the sewage collection was 84% , the sewage treatment was 68% and the pollution reduced to a 154.7 km.

WTE BARUERI Sludge Production (Barueri)

WTE BARUERI Idea - SUSTAINABLE SEWAGE SLUDGE. BIOGAS and SLUDGE are proprietary assets. GRANTING OF THE RIGHT TO EXPLOIT THE USE OF ENERGY POTENTIAL.

WTE BARUERI

Solution WTE BARUERI CONTRACT SCOPE SLUDGE / BIOGAS EPBL ELECTRICITY WASTE DULY TREATED FOR FINAL DISPOSAL ELECTRICITY

WTE BARUERI Required Scope Thermal drying of 500 tons / day of SLUDGE to convert them into DRY SLUDGE ELECTRICITY Production from Biogas processing obeying the following assumptions. Maintaining the temperature of the raw sludge stored within the currently existing digesters in the range of 35 °C to 37 °C by suppling thermal energy. Treat and allocate an environmentally appropriate way to all waste generated in the processes in place.

WTE BARUERI Obligations of Sabesp:: Digested Sludge supply ; quantity and quality. Biogas Delivery to the specified quality and in the following amounts: Up to 50,000 Nm3 / day from 1st to 5th year. Up to 100,000 Nm3 / day from the 6th year.
