en.Wedoany.com Reported - The U.S. Section of the International Boundary and Water Commission celebrated the one-year anniversary of Commissioner Chad McIntosh's tenure, marking progress on wastewater treatment expansion, cross-border sewage mitigation, and water infrastructure projects along the U.S.-Mexico border. A key milestone is the rapid expansion of the South Bay International Wastewater Treatment Plant, where staff increased daily treatment capacity by 10 million gallons in 100 days—a 40% boost—reducing the flow of untreated sewage into the Tijuana River Valley and nearby coastal communities. In a press release, the agency stated that over the past year, employees acted swiftly to enhance wastewater treatment capacity, secure equitable water supplies for American farmers and communities, and reduce flood risks for both nations.

The agency also reported progress on design work to further expand the treatment plant to a daily capacity of 50 million gallons, with the design expected to be completed later this year. The Commission signed Minute No. 333, a bilateral agreement requiring Mexico to construct and maintain new sanitary infrastructure in Tijuana while adopting wastewater and stormwater management practices that meet U.S. standards. Other initiatives highlighted by the U.S. Section of the IBWC include a pilot project using ozone nanobubble technology to reduce bacteria and odors in sections of the Tijuana River, as well as coordination with federal agencies on border water resources and flood control projects.
Chad McIntosh stated in the press release: "None of this work would be possible without the dedication of USIBWC engineers, operators, scientists, and field staff. In the year ahead, we will continue advancing solutions to the Tijuana River sewage crisis, upgrading aging wastewater infrastructure, and ensuring the treaties we administer continue to protect public health and environmental quality for future generations."
