Brazil's São Paulo state water utility Sabesp (Bovespa: SBSP3, NYSE: SBS) has authorized consortium Araucária Saneamento to kick off a 106mn-real (US$67.9mn) wastewater treatment project in Campos do Jordão city, a Sabesp spokesperson told BNamericas.
The consortium is led by Inima, a subsidiary of Spanish engineering group OHL. It is joined by Brazilian construction companies Cesbe Engenharía e Emprendimento and Constructora Elevação.
"With the 30-month project, we aim to increase wastewater collection in the city to 65% from 45% and wastewater treatment to 100% from 0% by 2013," the spokesperson said.
The group will build a plant using a biological membrane system for conventional pre-treatment, including sludge treatment and wastewater re-use components.
Work also includes installing 7.8km of interceptor pipeline, 10km of collector pipeline and three pumping stations.
Once completed, the system will have the capacity to treat 213l/s, serving up to 76,000 people. With the city's current population at about 48,000, the plant is expected to cover projected population growth until 2035.
Sabesp also has plans for a second phase, which will increase wastewater collection coverage in Campos do Jordão to 85%. This should be complete by 2016, according to the official.
