Sewage spike, odors worsen in San Diego’s South Bay after Tijuana pipeline collapse
People living and working near the polluted Tijuana River may have noticed more sewage flows and worsened sewer gas odors over the weekend. The U.S. International Boundary and Water Commission, or IBWC, said that’s because a 10-mile pipeline in Tijuana, dubbed the Parallel Gravity Line, collapsed Friday night. The line is supposed to transport wastewater to the San Antonio de los Buenos plant in Baja California, which is designed to divert flows from the Tijuana River by treating 18 million gallons per day before releasing them into the Pacific Ocean. Instead, the raw flows have been entering the river. According to IBWC data, flows in the river spiked from 10 million gallons on Friday to 34 million gallons on Sunday. … The IBWC also said that the Parallel Gravity Line has ruptured twice over the past two weeks.
