- Leak categorization by size (A, B, C) displayed on a user-friendly GIS dashboard
- Fast-developing leak alerts to prevent costly breaks and damage
How Does AQS Monitoring Work?
The magic lies in the sensors. AQS fixed sensors are installed along pipelines, typically on fire hydrants and valves. Each night, they record a 16 to 20-second audio sample and send this data to a cloud server. There, the system analyzes the sounds and performs correlation between every pair of sensors. If the same noise is detected at the same location, an alert is triggered pinpointing the exact leak spot. This daily routine means leaks can be caught early—before they escalate into major problems.
Sensor Technology and Installation
The type of sensor used depends on the pipe material, diameter, and installation point. For distribution lines, continuous monitoring is done using either accelerometers (which detect vibrations) or hydrophone sensors. Accelerometers are great for metal or asbestos cement (AC) pipes up to 24 inches, while hydrophones are suited for PVC and PE pipes. For transmission or trunk main lines, hydrophone sensors are tapped directly into the pipe. The Aquarius Multi-sensor combines a hydrophone and pressure sensor in one device, allowing utilities to detect both leaks and pressure transients simultaneously.
Why Continuous Monitoring Matters
Finding leaks early is the key to avoiding catastrophic breaks and costly repairs. Continuous monitoring means utilities don’t have to wait for visible signs of damage or customer complaints. Instead, they get real-time insights into their network’s health. This proactive approach not only saves water but also reduces operational costs and extends the lifespan of infrastructure. Plus, the system’s ability to categorize leaks by size helps prioritize repairs, making resource allocation smarter and more efficient.
Project Impact on Sustainable Development Goals (SDGs)
- SDG 6: Clean Water and Sanitation – by preserving potable water and reducing losses
- SDG 9: Industry, Innovation, and Infrastructure – through advanced monitoring technologies
- SDG 11: Sustainable Cities and Communities – by preventing water-related infrastructure failures
- SDG 12: Responsible Consumption and Production – optimizing resource use and minimizing waste
- SDG 13: Climate Action – reducing energy and water waste contributes to lower emissions
The Future of Water Network Management with AQS
AQS is setting new standards in water network monitoring. Its combination of sensitive sensors, big data analytics, and cloud connectivity offers utilities a powerful tool to stay ahead of leaks and infrastructure issues. As water scarcity becomes an ever more pressing global challenge, technologies like AQS’s will be essential in ensuring sustainable water management. The ability to detect leaks early, maintain operational efficiency, and optimize resources means utilities can provide better service while protecting precious water resources for generations to come.
