Sewage flows through canal from Mexico near San Ysidro, March 28, 2019.

The United States-Mexico border region is enduring the latest in a series of massive cross-border sewage tainted spills.

Federal officials in charge of monitoring the trans-border sewage situation on the U.S. side of the border said nearly 8 million gallons of tainted water flowed crossed the border in the Tijuana River channel.

The flow crossed the border from 7 p.m. Sunday evening through 10 a.m. Monday.

U.S. International Boundary and Water Commission officials said Mexican officials reported a water main break which poured water into the Tijuana River channel near the Lucerna Hotel.

The flows that crossed the border included water from that break as well as treated and untreated sewage.

A key pump station in the Tijuana River was unable to divert the flows, according to officials.

Mexican officials said repairs on the 16-inch water line began Monday morning.

Nearly 130 million gallons of sewage-tainted water has entered the United States since the beginning of September.
