In response to drought and water stress, the NSW government launched the $12.5 million Regional Leakage Reduction Program to address leakage across regional utilities. Aqua Analytics, selected for its expertise in water loss management, played a key role in the program, which spanned 30 months and involved collaboration with the Department of Planning and Environment, NSW Water Directorate, and local councils.
Key results include:
- Identification & repair of over 3,100 leaks
- 5.1 billion litres of water saved annually
- Improved overall network performance and reduced operational costs
Aqua Analytics demonstrated its commitment to water conservation by contributing to substantial water savings, supporting nearly 30 councils, and reinforcing sustainable water management practices across NSW.
What is Active Leak Detection?
Active leak detection identifies and locates leaks in a reticulated water supply. It can involve using various techniques and tools to detect leaks, such as visual inspection, acoustic listening devices, pressure testing, thermal imaging and advanced correlating loggers. Active leak detection aims to identify leaks early on before they cause more significant water loss or manifest as a disruptive main failure. Early detection and repair of leaks can prevent costly repairs, reduce utility bills, save energy, promote safety and protect the environment.
Our approach to Active Leak Detection is both comprehensive and technologically advanced. We utilise smart leak detection technologies that, when combined with the expertise of our highly skilled and professional Water Network Technicians, provide a thorough audit of all assets within a District Metered Area (DMA), Water Loss Zone, City, or Town.
Our ArcGIS ESRI software suite allows us to spatially report network defects and leaks immediately from the site and ensure tagging of network detects against Asset IDs to enhance asset management practices. Our software integrates seamlessly with a range of Enterprise Asset Management tools via full API integration, ensuring that all data is accurately and efficiently managed.
Benefits of Water Network Leak Detection
Reduction in Water Loss
Early detection and repair of leaks prevent significant water wastage, conserving this essential resource.
Cost Savings
By identifying leaks early, municipalities and businesses can avoid the high costs associated with water loss, such as treatment and pumping.
Enhanced Efficiency
Active Leak Detection improves the overall efficiency of water networks by ensuring that all components are functioning optimally.
Reduced Carbon Emissions – Help The Drive To Net Zero
Reducing water loss saves energy and carbon emissions in the water supply sector, helping cities and towns meet their carbon emissions targets.
Prolonged Infrastructure Lifespan
Regular monitoring and maintenance extend the life of water distribution infrastructure, reducing the need for frequent replacements.
Frequently Asked Questions
Why should a water utility undertake active leak detection?
The purpose of active leak detection is to find all the leaks that do not surface or come to the attention of the water utility through their standard procedures (for example, customer contact centre, insufficient pressure, or loss of water). The detection process involves teams of skilled leak detection technicians actively surveying an area to find leaks—generally using acoustic-sounding techniques or similar smart devices on all accessible water network appurtenances. The exact location of work may be in response to an increase in the minimum night flow (MNF) if the area is sectorised into a DMA or Water Supply Zone, an increase in the output from a treatment works or supply reservoir, or simply as a result of a systematic, regular leak detection program at predetermined intervals.
How are leaks detected in water supply networks?
Many technologies for water main leak detection utilise acoustic principles to identify and pinpoint leak locations. A pressurised water pipe will create a unique acoustic signature at the leak location due to the pressure differential between the inside and outside of the pipe. The water main acts as a medium for transmitting the acoustic signature of the water leak.
When water is escaping the pipe under pressure, it makes a distinct ‘hissing’ sound that can carry significant distances along the length of the water pipe and be detected on nearby service connections, hydrants or stop valves. Several factors influence the distance the leak can travel, primarily the pipeline material and diameter. For example, a 100mm cast iron water main will propagate the acoustic signal much better than a 300mm PVC water main. Key factors that influence leak detection capability and accuracy include:
- Pipeline material
- Pipeline diameter
- Pipeline pressure
- Leak size
- Leak type (or more specifically, leak shape)
- Backfill type
- Access to appurtenances
- Ambient & environmental noise
How does Aqua Analytics detect leaks?
We use advanced leak detection technologies, such as acoustic leak detection devices and cloud-based data analytics, to accurately identify and locate leaks within the water network. These devices can range from acoustic leak noise loggers, electronic listening sticks, leak noise correlators, and other specialised technologies such as trunk main leak detection tools. Aqua’s brand-agnostic approach means we objectively assess the best technologies for each leak detection project, ensuring our customers receive tailored solutions that deliver results.
Do you use AI to detect water leaks?
Our proprietary AI model, trained on a massive dataset of real-life sound samples, powers a cutting-edge “AI Predictor” in our cloud software when deploying acoustic leak noise loggers. This innovative tool provides a numerical likelihood of leaks, adding an invaluable intelligence layer to your water network management.
Why is leak detection important?
Leak detection is crucial for conserving water, reducing costs associated with water loss, maintaining the efficiency and longevity of water distribution infrastructure, and reducing carbon emissions associated with catching, treating, and pumping water around a distribution system. Early detection and repair of leaks prevent extensive damage and costly repairs.
How accurate are the leak detection technologies used by Aqua Analytics?
Our leak detection technologies, including acoustic sensors and correlators, are highly accurate. They enable us to pinpoint the exact location of leaks, even those that are not visible on the surface.
How do you report the findings from leak detection inspections?
We use the ArcGIS ESRI software suite to conduct comprehensive spatial reporting of network defects and leaks. This software allows us to provide detailed, precise, and actionable insights into the condition of your water distribution system. We always work with clients at the commencement of projects to understand their preferred reporting formats and frequency. If any data integrations are required, we also understand the security requirements and formats and establish these before project commencement to ensure timely and accurate data reporting.
