About 143 million gallons of sewage spilled into the Tijuana River during a period of more than two weeks, said a report released Friday.

No other sewage spill in the greater San Diego-Tijuana region has approached this magnitude in years, according to the environmental group Wildcoast.

The latest spill started around Feb. 2 and was not contained until Thursday, the U.S. section of the International Boundary and Water Commission said in its report. 

It apparently was caused by a rupture in a sewage collector pipe near the junction of Mexico’s Alamar and Tijuana rivers, the second of which drains into the Pacific Ocean on the U.S. side of the border.
