About us

Since the establishment of Sterner in the early 1990’s, our main interest has been water treatment technology. From our locations in four cities from the North to the South of Norway, we are working together to establish new technological solutions for optimal water treatment.

Water is a resource we all share. It is only on loan to us. We have to ensure that we return this in as clean a state as when we borrowed it. Sterner’s vision is to make this possible!

The source of our success is the adaptation of novel water treatment technologies to make effective, user friendly and safe solutions. By maintaining our deep interest for water, we remain thirsty for knowledge, allowing us to deliver the solutions of tomorrow.
