Baja California’s governor is preparing to declare a state of emergency in the coming days, hoping to draw financial aid for Tijuana’s strained and underfunded sewage system following a massive spill that sent millions of gallons of untreated wastewater from Tijuana across the border and into San Diego last month. The incident was triggered by the collapse of a major sewage trunk line in Tijuana, state officials say, and repairs led to the release of a large amount of untreated sewage into the Tijuana River channel, which empties into the ocean at Imperial Beach.
