Crews broke ground this spring on new pump stations and river gates meant to curb Tijuana sewage flows, but two pipeline collapses in May were a reminder of how fragile the existing system remains, according to the latest binational progress report. A quarterly report released this week by the U.S. Environmental Protection Agency (EPA) and the U.S. Section of the International Boundary and Water Commission outlined construction progress, funding releases, and challenges as the U.S. and Mexico work to address the decades-long Tijuana sewage crisis. The EPA released a batch of previously committed infrastructure funds after Mexico met its obligations under a 2025 agreement between the two countries — freeing Mexico to begin construction on two new projects aimed at reducing sewage flows into the Tijuana River.
