USIBWC Seeks Applicants for Lower Rio Grande Committee

The U.S. Section of the IBWC was notified at approximately 8:00 a.m. Mexico installed new electrical equipment at Pump Station CILA. The technicians installing the equipment partially shut down the pump station during the installation for nearly one hour. Approximately 300,000 gallons of Tijuana River water exceeded the capacity of the Station during the installation and entered into the United States. This new equipment will assist Mexico in the operation of Pump Station CILA. Note: Normal Tijuana flow consists of groundwater, stormwater (if applicable), untreated wastewater and effluent water from Mexico's treatment plant.

Mexico informed us that between 6:00 p.m. Feb 10 and 1:00 a.m. Feb 11 the flow from the Tijuana River exceeded the pumping capacity of Pump Station CILA which resulted in flow at the International Boundary, consisting of approximately 665,000 gallons. Note: Normal Tijuana flow consists of groundwater, stormwater (if applicable), untreated wastewater and effluent water from Mexico's treatment plant. Mexico has reported ongoing electrical issues are affecting the ability of the motors and pumps at the station and a new motor control center is expected to be installed within the week to assist in maintaining a consistent plant operation.

Mexico reported a partial electrial power failure at Pump Station CILA this morning between 6:00 a.m. and 8:00 a.m. Normal Tijuana flow which bypassed Pump Station CILA is estimated to be at 560,000 gallons. More information will be updated as soon as possible.
