City repairing sewage pipes to avert spill?
Mexico City, whose 20 million people produce enough sewage to fill an Olympic-sized swimming pool every minute, is fixing up its aging drainage system to avoid a pipe fracture that could flood entire neighborhoods, the subway and the airport with human waste.
Mayor Marcelo Ebrard recently unveiled a set of new pumps as the first part of a $1.2 billion spending plan to refurbish 99 miles of sewer tunnels that have not been fully inspected for 15 years.
«The danger is very high because if the pipe fails, a flood would have serious consequences for the city,» Ramon Aguirre, the head of the city?s water system, told Reuters.
The first $56 million will go to build four new pumping stations that will increase the city?s capacity to process the 40,000 liters of sewage it produces every second, marking the biggest investment in three decades.
?The problem of the drainage system, how to get the water out of the city, has been one of the primary concerns of this government,? said Ebrard, gazing at a canal outside the city filled with greenish-black bubbling sludge.
