County issues health warnings for Tijuana River Valley following sewage pipe collapse
A collapse in a major Tijuana sewage pipeline has sent millions of gallons of raw wastewater surging into the Tijuana River Valley, pushing a South Bay treatment plant far beyond its capacity and driving dangerous levels of hydrogen sulfide gas into surrounding neighborhoods overnight. The U.S. International Boundary and Water Commission reported the failure of Tijuana’s Parallel Gravity Line [last] Friday night. The line conveys wastewater across Tijuana and its collapse sent excessive flows to the South Bay International Wastewater Treatment Plant, which is designed to handle 35 million gallons per day. The plant sustained flows above 45 million gallons per day for 13 hours over the weekend and peaked above 60 million gallons per day for nine hours.
