A Brazilian consortium will start work on a 29mn-real (US$17.8mn) project in July to carry out sewerage work under phase III of São Paulo state's Tietê river sanitation plan, a spokesperson from state water utility Sabesp told BNamericas.
The consortium is made up of local construction and sanitation firms Jofege Pavimentação e Construção and Engenharia Obras e Tecnologia (Enotec).
The work involves building 2.5km of interceptor pipelines along the banks of the Pinheiros river, running southbound towards the neighborhood of Interlagos in the south of state capital São Paulo. The consortium will also install 4.4km of trunk collector pipelines.
The new network will direct sewage to Sabesp's wastewater treatment plant in Barueri. Work should be wrapped up by the end of 2012, according the official.
The initiative is being managed by Sabesp under phase III of the Tietê river cleanup, aimed at remediating contamination in the river and expanding wastewater collection and treatment services to prevent further pollution.
This phase has a total cost of 1.05bn reais, and is scheduled for completion in 2015. The work will benefit 1.5mn people with wastewater collection and 3mn people with wastewater treatment service.
