About Us

Gutermann Technology is a global technology leader in intelligent water loss management and acoustic leak detection. Founded in 1948, Gutermann develops high‑precision, firmware‑driven hardware and software systems that enable water utilities worldwide to detect, locate, and monitor leaks in water distribution networks quickly and reliably. Our solutions range from portable acoustic leak detection tools to permanent, fully automated network monitoring systems used to reduce non‑revenue water and protect critical infrastructure.

At the core of our products are embedded loggers, sensors, and correlating devices that combine firmware development, acoustic signal processing, modem‑based communication and cloud‑based analysis. Gutermann pioneered fully automatic correlation across distributed sensor networks, allowing leaks to be identified and pinpointed with high accuracy and minimal manual effort. Headquartered in Zug, Switzerland, with R&D facilities in Stuttgart and Ravensburg, we develop technology that directly contributes to sustainability by helping utilities preserve one of the world’s most valuable resources: water.
