SBIWTP is a federal plant at the U.S.-Mexico border. The project will provide essential rehabilitation of existing infrastructure at the plant and will also double its treatment capacity to 50 million gallons per day (MGD), with a peak hydraulic flow capacity of 75 MGD. The plant will remain in operation throughout design and construction.
“With decades of experience in wastewater construction, we bring a deep understanding of the complexities involved in projects of this scale," said Ankur Talwar, District Manager for PCL’s civil infrastructure division. "Drawing on our long history of partnering with Stantec, we are committed to delivering a successful project and providing essential infrastructure enhancements to provide clean water to San Diego and Tijuana."
The $42.4 million first phase of the project will cover Stantec’s full-scale design for expansion and rehabilitation of the plant, with design expected to be completed within 20 months. Following design, PCL’s construction of the project is anticipated to take about five years.
“This work is critical to addressing aging infrastructure and increasing wastewater treatment capacity for the area,” said Mike Watson, Senior Vice President and Director, Design Build, at Stantec. “We have worked with PCL on several progressive design-build projects, and we look forward to collaborating once again in San Diego to design improvements that will help local water quality.”

Expansion of SBIWTP, alongside wastewater infrastructure improvements in Mexico, will help eliminate up to 90 percent of untreated wastewater reaching the coast. This will provide cleaner, safer water for surrounding communities. The U.S. and Mexico will continue to partner in an effort to reduce transboundary flows of untreated wastewater.
This project is being conducted in partnership with the U.S. Environmental Protection Agency and the 2020 United States-Mexico-Canada Implementation Act.
