Sewage flow across the U.S.-Mexico border may temporarily increase in the Tijuana River Valley as part of a sewer line-repair project in Mexico starting this week.
In a news release issued Friday, the county Air Pollution Control District announced the project could also increase at South County beaches, as untreated wastewater is diverted. Air pollution levels also may increase.
Now in its second and final phase, the project was expected to start Tuesday, May 13, and take roughly one week to complete, APCD officials said.
The existing line moves untreated wastewater to the South Bay International Wastewater Treatment Plant in the U.S., and the San Antonio de los Buenos Plant in Mexico, according to the APCD.
The International Boundary and Water Commission will stay in touch with construction and project managers in Mexico, monitor progress and share updates, according to the ACPD.
The APCD monitors odor complaints and hydrogen sulfide levels for communities located near the Tijuana River Valley.
According to the county, residents in affected communities can reduce the impact of the hydrogen sulfide odors by limiting outdoor activities if the smell bothers them.
