Wastewater Collection System Rehabilitation and Improvements Project Tijuana, Baja California

Status: Completed

Background

Continuous spills experienced in the border region due to clogging and collapses of old sewer pipes in the Tijuana River Watershed resulted in the development of a sewer rehabilitation project for city of Tijuana. The proposed areas for rehabilitation, were prioritized by CESPT in coordination with BECC, EPA, and the State of California. The prioritization criteria included sewer line condition data; overflow, repair records, and users complaints;  potential  wastewater discharge volumes; and proximity to the  Tijuana  River  and the border. This project is referred to as Tijuana Sana.
