There are two major water treatment plants critical in the Tijuana River pollution crisis:
- San Antonio de los Buenos wastewater treatment plant in the town of Punta Bandera — a Tijuana metropolitan area town about 5 miles south of the border. It releases millions of gallons of mostly raw sewage into the ocean each day that migrates to San Diego County’s southernmost beaches.
- The South Bay International Wastewater Treatment Plant (SBIWTP) is a 25 million gallons per day secondary treatment plant located in San Diego County, California. It’s designed to deal for the growing demand for the treatment of wastewater from the sewage originating in Tijuana, Mexico, discharging it to the Pacific Ocean through the South Bay Ocean Outfall (SBOO), a four and one-half mile long 11 foot diameter pipe completed in January 1999.
