Starting Monday, authorities in Tijuana and Rosarito will ration water for the next two months because of a limited supply, according to the Baja California Public Service Commission. Roughly 140,000 households and businesses in the border cities will go without water service for up to 36 hours every four days. The service disruptions will be spread throughout seven districts. Customers will receive a 24-hour notice whenever water services are shut off in their district, officials said.
