Established in 1958, Three Hills & District Seed Cleaning Plant continues to stay current and modern by participating in accredited seed grading courses and technical workshops.

In 1991, Three Hills & District Seed Cleaning Plant's new facility was relocated and constructed on the west side of Three Hills. The building is complete with a modern line of equipment, which includes a colour sorter. 

The plant's staff specializes in a wide range of services provided year round, operating six 6 days a week at 24 hours a day when needed, to get the job done.
