What makes a modern leak detection system ‘modern’ is the way that leaks are identified, pre-empted, and resolved. Leaking pipes account for average losses of 20-30% of all piped drinking water globally, and this is by no means a new problem. Traditional water leakage detection often relied on a combination of public reports, routine inspections, and basic monitoring tools to identify issues. However, these methods were largely reactive, typically identifying leaks only after significant water loss or visible surface damage occurred. As water infrastructure faces increasing pressure from ageing assets, climate change, and growing public scrutiny over water waste, utilities are recognising that reactive strategies alone are no longer sufficient.
Fortunately, the tools available to utilities businesses have also evolved significantly. By moving beyond traditional leakage detection technologies and embracing more innovative leak detection systems, operators can manage their networks more effectively and reduce waste. Read on to find out more.
Understanding Water Leakage & Leakage Detection Technologies
For years, traditional leak detection relied on manual inspections and basic listening sticks, which were time-consuming and often failed to find small, hidden leaks for months. Modern water leakage detection is more sophisticated, using the latest technologies to provide enhanced accuracy and efficiency. This allows operators to move from a reactive ‘failure and repair’ model to a proactive strategy of prevention and targeted maintenance across large networks.
What are the Main Types of Leak Detection Systems?
So, what are the main types of modern leakage detection systems, and how can they be used in combination for a comprehensive network overview?
1. Advanced acoustic systems:
Modern acoustic sensors use software algorithms and machine learning to disentangle the sound of a leak from background noise. These systems can learn from each detection event, refining their accuracy to pinpoint issues with remarkable precision.
2. Smart water meters:
The widespread rollout of smart meters in homes and businesses provides utilities with a continuous stream of data on water usage. By monitoring consumption patterns in near real time, these devices can flag unusual or anomalous activity that might indicate a leak on a customer’s property, enabling swift intervention, often before the customer is aware of the issue.
Additionally, smart water meters provide accurate data that is used to determine true consumption of an area, thus being able to distinguish the leakage and the demand proportions from the total water supplied to the area.
3. Imaging and Surveying:
Infrared and thermal imaging cameras can detect temperature variations on pipe surfaces or on the ground caused by escaping water. This non-invasive monitoring method is particularly effective for locating hidden leaks that leach water into the ground without being visible from the surface.
Furthermore, advanced techniques now include the use of satellite imaging which can provide wide-area thermal and spectral analysis to identify subtle changes in vegetation health or soil moisture, significantly enhancing the capability to detect leaks over vast networks.
4. Water network management software:
Investing in a robust software platform, such as Netbase, allows you to consolidate data from acoustic sensors, satellite surveys, and other vendor systems. This approach streamlines your incident response strategy and supports a more predictive approach to maintenance planning.
How Investing In The Right Technology Boosts Efficiency
Adopting these and other advanced systems has tangible benefits for water utilities companies. For example, early water leakage detection can prevent small issues from becoming major or costly bursts, bringing cumulative savings.
What next?
At Crowder Consulting, we can help you implement a range of leakage detection technologies to reduce water loss across your network.
Our NetOps solution integrates with Smart Technologies such as Satellite data, and the Netbase platform also ingests smart data from vendor systems. This powerful combination enables analysis and visualisation within digital applications to support operational management activities. Data such as acoustic sensor alarms or satellite surveys provide crucial awareness and, in some instances, corroborate leakage investigations by combining diverse smart data sources.
