A Fort Collins water manager said a batch of bad beer or food processing by-products dumped into the city's sewer system was most likely responsible for killing micro-organisms at the water treatment plant that caused a foul odor, Thursday.
The water treatment managers at New Belgium Brewing Co. and Odell Brewing Co. said their breweries treat water used in processing on site -- or have strict accounting of wastewater -- the Fort Collins (Colo.) Coloradoan reported Saturday.
"We know where every gallon of liquid goes to," said John Bryant, chief operations officer at Odell.
New Belgium Brewing treats wastewater before discharging it to the city sewer system, said Brandon Weaver, the brewer's treatment plant lead operator.
"We're sending them nice, clean water," he said.
There are no known food processors in the area that drain to the treatment facility, said Brian Janonis, the city's water resources and treatment manager.
