Argentina's Buenos Aires government expects a US$190mn project to control flooding on the Maldonado river basin to wrap up in 2012.
The four-year initiative includes building two drainage tunnels measuring 10km and 5km respectively, plus another 46km of secondary ducts to collect and drain the city's rainwater. The project is expected to quadruple current levels of flood protection in the basin, the city government said in a release.
"This is the most important engineering project in the city in decades. We're finishing up works on the first tunnel that stretches to Niceto Vega street in Palermo, and for the beginning of 2012 we will complete the storm drain that reaches the [Maldonado] basin, in Flores," said the city's chief of staff, Horacio Rodríguez.
The project falls under Buenos Aires' US$500mn master plan to install flood protection infrastructure in all of the city's river basins.
