A Craft Brewery Is Saving This Montana Town Thousands in Water Treatment Costs

Havre, Montana's Triple Dog Brewing Company is putting its waste to good use. Three years ago, Drue Newfield, the manager at Havre's wastewater plant, had an idea for a collaboration. He wanted some of the local brewery's spent barley. He believed the mash could help remove nitrogen and phosphorus from treated water. So now, every morning, 16 gallons of spent barley is emptied into the water before it goes into treatment pools. If Newfield hadn't reached out to Triple Dog, the plant would have to buy a chemical called alum. And that equals a savings of at least $16,000 a year. The larger city of Bozeman, Montana tried the same thing, but the program was cancelled.
