A critical area of Tijuana’s wastewater system, which repeatedly fails, sending millions of gallons of untreated sewage a day into the binational Tijuana River, is being upgraded. On Monday, officials with Mexico and U.S. governments and the North American Development Bank (NADBank) broke ground on a project to improve the PB1A and PB1B lift stations. The pumps move wastewater from a larger pump station in Tijuana, called PBCILA, across the U.S.-Mexico border to the South Bay International Wastewater Treatment Plant that’s located in the Tijuana River Valley. … [O]fficials said they are also beginning work on a project, dubbed Tijuana River Gates, to replace 35,700 feet of deteriorated wastewater pipes along several sections of the city’s wastewater collection system that repeatedly leak into the Tijuana River.
