Buenos Aires prepares for El Niño with drainage improvements
Summary and headline written by AI from the source article. How we work
The city of Buenos Aires, Argentina, completed a key stormwater infrastructure project on Dorrego Avenue in Palermo to improve water drainage and prevent flooding.
The project, which involved replacing 293 meters of underground pipes and adding six access points for maintenance, is part of a larger preventative plan of 29 works undertaken by the Buenos Aires city government. Officials anticipate intense rainfall and severe storms due to the approaching “El Niño” climate phenomenon later this year.
The city began the work in April after identifying obstructions in existing drainage systems. In addition to the Palermo project, crews are also working on the Cildañez stream, an 11-kilometer underground waterway, to remove over 37,000 cubic meters of accumulated sediment. The government estimates this cleaning will restore up to 15% of the waterway’s drainage capacity. The city government has also implemented a preventative system activated by weather alerts.
This system includes monitoring high-risk areas and deploying teams across the city’s 15 districts to check 177 specific locations. Since Jorge Macri took office, the city has completed 64 projects to expand, adapt, repair, and clean the stormwater and hydraulic network, installing over 13,000 meters of new pipes.
