About Calumet

Since 1961, the Calumet name has been synonymous with quality. Today, Calumet is a division of Imperial Industries. At Imperial’s headquarters in Wausau, Wisconsin, we’ve been designing and manufacturing specialized liquid waste handling and storage solutions for more than 35 years – constantly evolving to meet the industry’s changing needs. That dedication to growing alongside our valued customers has allowed us to advance from a maker of agricultural feed bins into the industry leader in manufacturing liquid storage and handling equipment. And we’re proud to carry on Calumet’s tradition of manufacturing the highest-quality products for farm operations of all shapes and sizes.
