Two weeks after emergency repairs, Tijuana wastewater line collapses again
A pipeline that carries wastewater through Tijuana has collapsed again — just two weeks after Mexico made emergency repairs to the same line. The U.S. Section of the International Boundary and Water Commission (IBWC) on Saturday reported an overnight collapse on the Parallel Gravity Line. The cause of the collapse is unknown. Mexico has shut down several pumps along the border to allow crews to make repairs. That same line failed on May 14, resulting in emergency repairs that were completed on May 16. … The IBWC said it’s monitoring expected flows, sediment, and trash in the canyon collectors and is ready to respond. The agency also said it is coordinating with Mexican water authorities and pressing Mexico to bring all suspended pumps back into operation as quickly as possible.
