Mexico's federal district (DF) mayor Marcelo Ebrard has said the city's drainage system will be ready to cope with the rainy season, which begins in May.
Following unusually heavy rain in the city over the weekend, Ebrard carried out an inspection of the third phase of work to repair the drainage network, according to a DF government release.
The city government is spending 1.8bn pesos (US$149mn) to repair the city's drainage system, which in recent years has tended to collapse in the rainy season, causing floods in the city.
Work involves lining drainage tunnels to prevent deterioration caused by gases.
"What we are doing is practically rebuilding [the drainage], so it will remain this way for the next 20 or 30 years," Ebrard said.
Work also began last year on the city's Túnel Emisor Oriente (TEO) drainage tunnel, which is being built by consortium Comisa, comprised of construction giant ICA, its subsidiary Cotrisa and local conglomerate Grupo Carso.
Billed as the world's largest drainage tunnel, the 62km TEO will increase Mexico City's drainage capacity by 150m3/s to cope with heavy precipitation during the rainy season.
