GUTERMANN is a global leader and innovator in intelligent water loss and leak detection technologies.

At GUTERMANN, we are dedicated to tackling the worldwide problem of water loss in urban water infrastructure.

We are a third-generation privately owned family enterprise with headquarters in Baar, Switzerland, and regional offices in Europe, North and Latin America, the Middle East, South East Asia and Australia.

GUTERMANN has been specialising in the design, manufacturing and distribution of all conventional acoustic leak detection equipment for more than 60 years. With a constant focus on innovation, we have often been at the forefront of new product developments in our sector, always pushing the boundaries of water leak management technology and often copied by our competitors but never quite matched. Thanks to our tireless commitment to product quality, functionality and user-friendliness, GUTERMANN has become a synonym for precision, quality and reliability in leak detection technology worldwide.

GUTERMANN has often been the first to introduce a new technology or advanced technical features. For the last 10 years we have put a lot of efforts into realising our vision of a completely automatic, unmanned and permanent network monitoring system which allows the user to identify and pinpoint leaks – even small and difficult ones – anywhere in the water network. From the Control Room, the water loss manager can review, in real-time, his entire distribution network, and analyse problematic network districts and pinpoint existing and new leaks in seconds. Thanks to the powerful and attractive ZONESCAN NET user interface and measurement database, the operator can use invaluable current and historic network data to track the state of his pipe network, perform benchmarking between different sectors, thus helping to anticipate negative network events such as pipe breakages. The system allows the smart utility to take informed asset management decisions, such as optimal repair work and pipe replacement times. Smart cities use Intelligent Water Loss Management from GUTERMANN.

ZONESCAN, with the flagship products ZONESCAN ALPHA and ZONESCAN NET, is our fixed network platform. After the first few installations we have continued to hone and perfect both the hard- and the software. In 2010, after extensive testing by the client, GUTERMANN delivered the largest such installation in the world to a country in the Gulf region. At the same time, a city in Germany scaled up their successful pilot site to cover the entire city network, after finding a massive leak within days of the system installation that paid back for the costs of the system in less than a month. The results are striking!

GUTERMANN has managed the quantum leap from the hardware manufacturer to the provider of a fully automatic water loss alarm turnkey solution.

Permanent Network Monitoring technologies allow utilities to identify and pinpoint leaks in their monitored pipe network moments after occurrence and initiate appropriate actions. Permanently installed intelligent sensors provide daily information (noise level histograms, frequency spectrum, correlation data, actual sound recordings) and therefore provide the operator with the best possible solution in terms of acoustic leak detection capabilities.


Our high-performance leak locating correlators are appreciated by customers for their physical robustness, their elegant design, their long-term reliability and their ease-of-use. Lab tests have also shown that the performance and accuracy of our correlators are among the highest in the industry. Choose between various levels of correlators that can be used in standard situations or more difficult environments (including trunk main leak detection).


Providing superior sensors and greater amplification than most other acoustic leak detectors in the market, the Aquascope product range will help leakage operators find more leaks.


Our pipe and valve locators complete the range of acoustic leak detection equipment. Our equipment is designed to be effective and easy to use.


GUTERMANN’s Zonescan 820 product range is cutting-edge and outperforms all other loggers available on the market. They are extremely small and robust, have the highest sensitivity, the strongest radio (proprietary radio), smart firmware, and nonetheless an impressively long battery-life. But most importantly, our loggers do not only provide noise-level data and advanced spectrum analysis, but they can also correlate and are therefore able to pinpoint leaks with high accuracy.
