Brazil's Rio de Janeiro state government plans to call a 1.6bn-real (US$989mn) tender in July for sanitation work in Rio de Janeiro city, government news service Agência Brasil reported.

The plan, being carried out in cooperation with state water and sewerage utility Nova Cedae and the city hall, entails hiring firms to collect and treat sewage in 21 neighborhoods throughout the western region of Rio.

Half of the region's sewage is currently released into the local rainwater runoff, and only 4% is treated properly.

Rio de Janeiro city, through its municipal waterworks organization Rio-Águas Foundation, will oversee the work, which involves quadrupling the current sewerage network through the construction of 19 sewage treatment plants and 221 wastewater pumping stations, the report said.

By 2016, sewage collection and treatment in the region should reach 40%, with the aim of 90% by 2036.
