A. DESCRIPTION OF SERVICES

1.0 BACKGROUND. The South Bay International Water Treatment Plant (SBIWTP) was initially designed as a twenty-five million gallon per day (25 MGD) wastewater treatment plant located at 2995 Clearwater Way, in San Diego, California, on the International Boundary. Construction of the plant’s advanced primary treatment was completed in September 1997, and construction of the secondary treatment was completed in May 2011. From 2011 to 2025, the plant treated an average of 25MGD/day of wastewater originating in Tijuana, Baja California, Mexico. SBIWTP is operated under the authority and at the direction of the United States Section, International Boundary and Water Commission (USIBWC). An average of 25 MGD of effluent is discharged through the South Bay Ocean Outfall (SBOO) which is subject to the requirements of the National Pollutant Discharge Elimination System (NPDES) Permit, Permit Number CA0108928, Order Number R9-2023-0009, and Order Number R9-2026-0005, As Amended. The NPDES Permit is issued by the California Regional Water Quality Control Board (CRWQCB). It is anticipated that a new NPDES Permit will be issued during the contract period that may have additional requirements outside the current scope. When needed, a modification to this Contract will be prepared to address additional permitting requirements.
Information describing the SBIWTP, SBOO, and other related infrastructure, are referred to as The Facility.
