To curb the flow of polluted waters into the Pacific Ocean, the United States, and Mexico will upgrade Tijuana River wastewater facilities, said a KNSD report.
The San Diego County report, the Needs and Opportunities Assessment, outlined 27 U.S. projects to improve waste treatment.
Sewage waste runs into the Pacific Ocean from the Tijuana River 138 days out of the year, according to the report.
County officials claimed it could shrink that number to 12 days per year with its proposed projects, a 91% reduction.
The county intends to do this by building new facilities along San Diego’s portion of the Tijuana River that can handle the overflow of wastewater from the Mexican water-treatment facility.
This facility is unable to operate during rainy days, said KNSD.
The county is proposing three strategies to deal with the substantial overflow.
The first method is to treat the contaminated water and then pump that water into the deep ocean through the South Bay Ocean Outfall system.
The second strategy is to pump the raw wastewater into the deep ocean through the outfall system.
The third proposal is to create in-stream basins, which would trap trash and sewage to be later collected.
The International Boundary and Water Commission announced Tuesday the Tijuana pump station would be rehabilitated.
This is after receiving the equivalent of about $3.6 million from Mexico’s National Water Commission.
According to Jesus Luevano, the Mexican secretary of the International Boundary and Water Commission, the improvements to the pump stations are scheduled to be completed this year.
He said this will reduce dry-season wastewater runoff by (70%) seventy-percent.
