Our History

The Darrington family have been in the water conditioning business since 1956 when Orville Darrington purchased a dealership in Yankton, SD. In 1958 Arnold joined his brother as a partner. Their sons were active in the dealership with Dan, who was then a teenager, working after school regenerating portable tanks.

In 1963 Arnold purchased the dealership in Mitchell. Dan worked doing bookwork, deliveries and regenerating softeners on weekends and during summer breaks from the University of South Dakota.

After graduation from USD in 1967, Dan was hired by the St. Paul Insurance Companies and worked for fourteen years in St. Paul, Des Moines, Waco and Dallas – Ft. Worth, TX.

In 1976 the dealership was purchased from Arnold by Pat Darrington, Dan’s brother, who operated the business until 1981 when Dan and Joanne Darrington purchased it and Pat started a dealership in Phoenix, AZ.

Since 1981 Dan and Joanne have worked with all types of water treatment for a wide range of water from well water to rural water. We are a family owned business that services what we sell and/or rent.
