en.Wedoany.com Reported - The Mexican Section of the International Boundary and Water Commission has restored the operation of the PBCILA wastewater pump station, which had been shut down for equipment protection due to heavy rain since November 15, 2025. Following the restart, the South Bay International Wastewater Treatment Plant can once again receive wastewater from the Tijuana sanitation system, with a maximum daily treatment capacity of 35 million gallons.

Since March, staff have conducted sediment removal and equipment maintenance in preparation for the pump station's restart. The resumption of operations will enhance cross-border wastewater treatment capacity, reduce the discharge of untreated sewage into the Tijuana River, and improve water quality in the river and downstream U.S. communities.

The PBCILA wastewater pump station is a critical component in reducing cross-border wastewater flow. During its shutdown, the Tijuana River faced risks of water quality deterioration. This restart signifies progress in the ongoing bilateral cooperation between the United States and Mexico in wastewater treatment and water pollution control.

The International Boundary and Water Commission is responsible for coordinating water resource and wastewater treatment projects along the border between the two countries. The restoration of this pump station will support the stable operation of the South Bay International Wastewater Treatment Plant and reduce the frequency of overflow pollution incidents.
