KUHN company was established in 1926 by Franz Kuhn, a plumber.

During the first years after the foundation, the local communities of Höpfingen and Schweinberg started to build-up their systems of municipial water supply. So the new-founded company had a new field to plow and took the chance.

In 1955 Franz Kuhn`s sons Josef, Guenther und Norbert Kuhn joined him in his company. They specialised in different fields of work: installation, elektrotechnics and domestic supply.
