The tequila overflowed at a rate of 100 gallons per minute, resulting in 1,500 to 1,800 gallons entering the city sewer system, said Phil Lynch, a spokesman for the Brown-Forman Distillery.
Fire and sewer officials were called because of the flammability of the 80-proof liquor, he said. Water was used to dilute the spilled alcohol.
``It was a simple case of human error,'' Lynch said.
