A pipeline used to send wastewater from Tijuana to the a treatment plant in San Diego ruptured Feb. 10, the U.S. International Boundary and Water Commission (USIBWC) reports. The rupture sent sewage into and through Stewart’s Drain, but no wastewater reached the Tijuana River channel due to efforts from the USIBWC and its contractors Veolia and INBODE. The transboundary flow was stopped using portable pumps and vacuum trucks, and ultimately lasted from approximately 5 a.m. until 6:30 a.m. The ruptured pipe was repaired by 9 a.m. The incident occurred as the IBWC finalized repairs of Junction Box 1 (JB-1), which is part of a network of infrastructure that carries wastewater from Tijuana to the South Bay International Wastewater Treatment Plant (SBIWTP) in San Diego.
