From the archive
Sewer cleaning in Switzerland since 1958 — the roots of today’s group.



Every thriving modern society relies on what remains invisible. Decades ago, our journey began not in boardrooms, but deep underground—confronting the harshest realities of European infrastructure. It took true resilience to pioneer an industry where others only saw hidden problems, setting the very standards of underground services with foundational pioneers like Mökah and keeping the vital, unseen arteries of our cities flowing.
From those first defining steps in Infrastructure, we realized that preserving the pulse of a changing Europe required more than maintaining pipes and networks. We expanded into the Industrial sector, delivering critical precision to the engines driving the continental economy. And because resilient infrastructure is inseparable from public well-being, we took the natural next step: Environmental Health, protecting water safety, urban ecosystems, and the communities we live in.
Today, KSG is not just the sum of its history. We are the integrated European force that safeguards our continent—from the depths of the underground to the air we breathe.
