Gutermann product information - 1980s

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

GUTERMANN is a global technology leader and innovator in intelligent water loss technologies and leak detection technology. 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 managed the quantum leap from the hardware manufacturer to the provider of a fully automatic water loss alarm turnkey solution

GUTERMANN aims to shape the future. We lead the development of intelligent water technologies that help reduce the loss of potable water due to inefficiencies in our infrastructure and therefore preserve water as the world’s most valuable resource. GUTERMANN is a clean-technology leader that ultimately allows people to have a better life in a more sustainable society.

Zonescan Alpha product set

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! Read more about our success stories in the Case Study section.

GUTERMANN is a proud technology partner of a number of world-leading multi-billion turnover technology companies. All of them have recognised that GUTERMANN has a unique product portfolio and a clear technological advantage in its field.

GUTERMANN is very proud to be able to give back to the world community. For more than 65 years, our company has been striving to make the best products that will help the utilities in this world to reduce water loss from leak pipes, the number one fresh water waster that exists still today. We think that we have come a long way and achieved real impact in the technological area.

At the same time there are countless other organisations and inviduals that are doing THEIR best to improve the water and sanitation situation for those parts of this world's population that are not as fortunate as us.

In 2014, GUTERMANN has started to donate money to specific projects that we are going to present in this space, inviting YOU too to get excited about them and donate money to these projects.


GUTERMANN is a world leader in acoustic leak detection technology. Our product range covers all areas of traditional acoustic leak detection. Most recently, thanks to our Permanent Network Monitoring technologies, we have established ourselves as the leaders of Intelligent Water Loss Management.

Intelligent Water Loss Management is a holistic approach to leak detection. The overarching method is to use permanent network monitoring technology in your water distribution network in order to track all leak related events and non-events in one centralised management platform and real-time, follow through with events through managed event ticketing from alarm to repair, and gain complete transparency over the condition of your pipe network. When an alarm is generated somewhere in your network, you first perform online analysis of the specified event. If necessary, you go onsite and perform additional localisation and leak listening work, using conventional leak detection equipment such as ground microphones and leak noise correlators. Once the appropriate action has been taken (leak repair, pipe replacement, or only continuous surveillance of the leak), you feed back the action and respective location, leak information, pipe data or other information (such as previously unknown PRVs, electro generators or leaky house connections) into the management system. This way you continue to build ever better knowledge of your water network which will help you take more effective decisions about your pipe network (such as pipe replacement cycles or appropriateness of various pipe materials). Gutermann covers the full product range for you to become an intelligent utility.

  • Permanent Network Monitoring
    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.
  • Acoustic Microphones
    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.
  • Leak Noise Correlators
    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).
  • Correlating Leak Noise Loggers
    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.
  • Pipe & Valve Locators
    Our pipe and valve locators complete the range of acoustic leak detection equipment. Our equipment is designed to be effective and easy to use.
