Drinking water losses and how to prevent them - SebaKMT® Megger Germany GmbH

Water is one of our planet's most valuable resources. A safe and efficient drinking water supply is essential for households, industry, and agriculture. However, billions of liters of drinking water are lost worldwide every year due to undetected leaks and burst pipes. This poses enormous challenges for water suppliers: in addition to economic losses due to lost water, there is also the threat of environmental pollution and supply bottlenecks.

Modern technologies make it possible to identify and reduce these losses efficiently. In this guide, you will learn about the causes of drinking water losses, how innovative methods contribute to leak detection, and which SebaKMT® solutions can help you monitor and protect water networks sustainably. With practical examples and clear explanations, you will gain valuable insights into modern technologies for leak detection and network monitoring.

The causes of drinking water losses

Drinking water losses are a global problem affecting both urban and rural supply areas. The causes of water losses are varied and often difficult to identify. There are both physical and administrative water losses, but this guide focuses on physical losses—i.e., water that escapes from the network through leaks and pipe breaks.

Common causes

Pipe bursts and leaks

Water pipes are constantly exposed to various stresses – whether due to natural aging, material fatigue, corrosion, or external influences such as subsidence or construction work. Older pipes made of materials that lose stability over the decades are particularly problematic. Corrosion in metal pipes, for example, can cause the wall thickness to continuously decrease until cracks or breaks eventually occur. Without regular inspections and preventive measures, this often goes unnoticed for a long time, so that small leaks grow larger over time and considerable amounts of drinking water are lost. In unfavorable cases, pipe breaks can wash away entire streets or building complexes and cause immense damage.

Aging infrastructure

Many water supply systems were built in the post-war period and have now reached the end of their planned service life. Pipes made of materials such as gray cast iron or asbestos cement are particularly susceptible to cracks and breaks. Since water pipes are mostly underground, their condition is invisible to the naked eye. Without regular maintenance and modernization, there is an increased risk of gradual damage that accumulates over many years. Especially in regions with strong population growth or increasing water demand, outdated networks quickly reach their capacity limits, which further accelerates wear and tear. Timely renewal or renovation can help water suppliers avoid high follow-up costs from emergency repairs and water losses.

Lack of monitoring systems

Many supply areas still rely on outdated or purely reactive methods, which means that leaks are only detected when visible damage occurs or customers report water losses. As a result, large amounts of water are lost unnoticed over many years. Modern monitoring systems offer the possibility of continuously analyzing the condition of the network and identifying problems at an early stage. Smart sensors and cloud-based systems such as POSEYEDON® enable automatic data evaluation in real time, so that leaks can be detected before they cause major damage. Investing in preventive monitoring pays for itself quickly, as undetected water losses incur high financial and environmental costs.

Print management issues

Water networks depend on optimal pressure control within the pipes. However, excessive or fluctuating pressure can cause considerable damage to the pipes. Especially in older networks that were not originally designed for modern high-pressure requirements, excessive water pressure can enlarge existing cracks or cause new leaks. Conversely, if the pressure is too low, not all consumers will be supplied with sufficient water. Intelligent pressure management—for example, through the use of pressure sensors and automated control systems—helps to operate the network efficiently and gently. This prevents material fatigue and unnecessary stress, extending the service life of the infrastructure and minimizing the risk of damage.

In order to reduce drinking water loss efficiently, utilities must take appropriate measures at an early stage. Modern technologies enable precise leak detection and long-term monitoring of water networks.

Methods for locating leaks in drinking water systems

In order to successfully minimize water loss, leaks must be precisely located. Traditional methods are often time-consuming and inaccurate. Modern techniques enable fast, cost-effective, and reliable leak detection.

Acoustic leak detection

Acoustic leak detection is a proven method for detecting leaks and utilizes the principle that escaping water produces characteristic sounds.

Correlators analyze noises in the pipe system and use sensors to calculate the exact location of the leak. This method is particularly suitable for long pipe sections.
Ground microphones are used to detect leak noises directly above the pipeline. This allows leaks to be located precisely.

Network monitoring with IoT technology

Thanks to advances in sensor technology, water networks can now be monitored continuously. IoT-based systems detect leaks at an early stage and send real-time data to operators.

SmartEAR® is an example of a modern, intelligent solution for continuous leak monitoring. Wireless transmission via LTE-M / NB-IoT enables reliable data transmission and fast response times.

Tracer gas method & other physical methods

Tracer gas method: This method uses a special gas that escapes at the leak site and is detected by sensors. Particularly suitable for areas that are difficult to access.

Prevention: Surveillance and monitoring of drinking water networks

In addition to selective leak detection, continuous monitoring of water networks is crucial. Intelligent monitoring allows problems to be identified and rectified at an early stage before major damage occurs.

Importance of continuous data collection

A major problem with drinking water losses is that many instances of damage are not detected immediately. Leaks often occur over months or years before they become visible or cause major damage. Without targeted monitoring, water suppliers lose large quantities of valuable drinking water every day—a loss that could be avoided.

Smart sensors detect changes in the water network in real time. They measure pressure changes, noises, and water flow rates and immediately detect deviations from normal conditions. This allows patterns to be identified that indicate leaks or weak points in the network. By capturing this data immediately, utility companies can take proactive action instead of waiting until significant damage has already occurred.

Another advantage is the long-term documentation of network stability. Continuously recorded data allows signs of wear to be detected before they reach critical levels. This enables predictive maintenance, allowing repairs to be carried out in a more targeted and cost-efficient manner. Smart monitoring systems thus not only help to reduce water losses, but also ease the financial burden on utilities.

Advantages of cloud-based systems such as POSEYEDON®

Digitalization has also made great strides in water management. Modern, cloud-based systems such as POSEYEDON® enable a completely new type of network monitoring. While traditional systems rely on manual checks and local measurements, cloud-based solutions allow for centralized collection and evaluation of all data in real time.

All collected information is stored directly in the cloud and can be accessed and analyzed at any time. This gives utility companies a complete overview of the condition of their network and allows them to identify deviations immediately. Thanks to intelligent algorithms, POSEYEDON® recognizes patterns and trends in the measured values and can indicate potential problems at an early stage.

One major advantage of cloud technology is fast and accurate decision-making. For example, if a printing anomaly is detected, immediate action can be taken to prevent further damage. In addition, centralized management enables better collaboration between different departments and locations, as everyone involved has access to the same up-to-date data.

The combination of POSEYEDON® with modern sensor technologies and IoT applications creates an efficient early warning system that helps water suppliers minimize water losses and ensure a sustainable infrastructure.
