en.Wedoany.com Reported - A wastewater pipeline on the US-Mexico border has ruptured twice in two weeks. On May 30, the U.S. Section of the International Boundary and Water Commission (IBWC), which handles binational water issues, reported two breaks in the pipeline system known as the parallel gravity line, which transports wastewater to the San Antonio de los Buenos wastewater treatment plant near Tijuana.

Similar ruptures have occurred in these pipelines over the past two decades. Mexican authorities are constructing a new international collection system to replace much of the aging infrastructure on their side of the border. Despite studies showing negative health impacts, discharges into the Tijuana River continue.

The U.S. IBWC stated that the exact cause of the most recent collapse remains unclear. The Mexican commission shut down several pumps along the border to allow repair crews to fix the issue. The U.S. IBWC is monitoring the flow of raw sewage, trash, and sediment in its canyon collectors on the U.S. side, which intercept and divert dry-weather cross-border flows and sewage from Mexico, sending them to the South Bay International Wastewater Treatment Plant on the U.S. side of the border.

U.S. IBWC Commissioner Chad McIntosh contacted Mexican IBWC Commissioner Adriana Reséndez on May 31, requesting round-the-clock repairs and urging Mexico to do everything possible to prevent sewage from flowing into the Tijuana River. Commissioner Reséndez stated that Mexican authorities are working on multiple fronts to complete the work as quickly as possible.
