Storms and infrastructure breakdowns keeps sewage flowing from Tijuana into San Diego County

(UI) – According to The Hill, the International Boundary and Water Commission reported that 22 billion gallons of raw sewage continues to flow from Mexico into San Diego Country since December. While sewage flows have decreased to 106 million gallons per day, the continued contamination is exacerbated by two out-of-service waste water collectors.

Since the Tijuana River Watershed flows into Mexico before returning to California, “anytime they have any raw sewage discharge to the Tijuana River, it ends up in the U.S.,” Hassan Davani, an assistant professor at San Diego State University, said to The Hill.

Wastewater flow from storms isn’t the only water problem San Diego County is dealing with; breakdowns in sewage infrastructure, such as pipeline ruptures causing pumping deactivation, make the issue worse.

Parts of the Southern California coast remain inactive due to unsafe levels of bacteria, including Imperial Beach Shoreline, Border Field State Park and Tijuana Slough National Wildlife Refuge.
