Proven automated water-leak monitoring system

The AQS-SYS correlated detection system is a game changer in water leak detection and asset management. The system informs you with certainty when a leak is starting to develop, giving you its exact position, long before the damage is caused. AQS is based on correlating sensors that integrate 3G cellular communication, GPS synchronization and cloud-based automatic signal processing.


AQS-SYS is a complete automated water-leak detection system.

  • We provide all the infrastructure including hardware, communication, cloud console and service
  • We provide you with up-to-date information on pipeline condition and leak status
  • We provide a GIS-based dashboard, complete with maps, graphs and event history to aid you in decision-making regarding water distribution system maintenance and service

Aquarius Spectrum AQS-SYS is not just a product or just a service, but a complete and comprehensive solution for leak monitoring, repair and pipe maintenance. It brings you a clear, accurate and updated picture of the condition and integrity of your water pipeline and additionally sends out automated notifications of leaks as they develop. You can observe your water system through the AQS-SYS web interface at any time and make your own analysis of the leak map/GIS. In addition, our water engineers are available every day for advice and consultancy and all this is offered as part of the service.

AQS-SYS is an effective system for maintaining urban water distribution assets. Its acoustic sensors are installed on the water supply infrastructure and so it monitors the entire water system of a town or city 365 days a year. Leaks are detected by acoustic correlating sensors and located the moment they start (holes from 1.5 mm) that transmit data via 3G cellular communication. Automatic notifications are issued to the facility engineers, indicating the location of the fault on the map while the system continues to monitor the pipe for further deterioration.

Primary Benefits

  1. A smart solution to efficiently maintain your water network by online monitoring of leaks and pipe condition.
  2. You will cut collateral damage from pipe bursts by catching the leak while still small.
  3. You will reduce NRW losses far more than with a survey-based approach. See Case Study
  4. You will manage your water O&M activities more efficiently.
  5. We make it simple by showing you where the leaks are and their intensity. All that’s left for you to do is fix the point of failure.
  6. Once the leak has been discovered by AQS-SYS, you will need to employ water leak detection equipment to pinpoint and mark the position ready for the repair team (see the unique mobile iQuarius).
  7. You will maintain high service to residents: You will reduce the number of water stoppages, you will be able to notify in advance of urgent repairs by catching impending bursts before they happen and you will even be able to notify residents in some cases of leakage identified below private yards and buildings.
  8. Actively advance an eco-friendly policy by saving energy due to reduced water wastage.


Better Management of O&M Activities

  • You will be able to prioritize your asset replacement based on accurate and organized data of all leaks development history.
  • You will know exactly which sections to replace, based on the condition of pipes and not their age
  • You won’t waste your budget replacing serviceable pipes that are in good condition
  • You will prevent many major water pipe bursts by catching them in time
  • You can plan infrastructures projects in advance

AQS-SYS enables detection of very small leaks that cannot be detected by surveys and noise loggers, owing to a continuous correlation-based detection method that has been proven in thousands of installed AQS-SYS sensors.

By detection of all evolving leaks, AQS-SYS allows you to prioritize leak repair and water pipe segment replacement, based on the leak’s flow rate due to pipe deterioration, thus saving water and saving money fixing worthless pipes. The system also detects sections with high corrosion so you can treat these areas accordingly.

Right now, as the cost of water leak surveys per mile is high, only a small percentage of your inventory is budgeted to be surveyed each year. Furthermore, identifying sources of pipe failure requires considerable skill on the part of the water surveyor.
AQS-SYS automates the process and makes you less dependent on human expertise and less subject to human error.

  • Use your water leak survey budget effectively
  • Direct leak detection teams to within 10 yards of known leaks
  • Optionally use the iQuarius™ solution to pinpoint leaks to an accuracy of 1 foot.

Advanced Acoustic Sensor Technology

The AQS acoustic vibration sensors are the backbone of the system. They incorporate a unique highly sensitive thin-film sensor technology and can be configured to respond to frequencies appropriate to different types of piping such as metal, plastic and others.


Continuous Correlation for Leak Detection and not Only for Pinpointing

Aquarius-Spectrum systems use correlation-based leak detection. This puts it far ahead of other “correlation on demand” systems that make their initial detection of leaks based on noise logging and only afterwards employ correlation techniques to improve the accuracy of positioning. The continuous correlation approach needs high data volumes and synchronization of each sensor. The AQS system therefore uses a 3G cellular communication modem and GPS synchronization to transmit high-resolution acoustic signals to the central analysis server.

The Aquarius-Spectrum algorithms therefore have very large amounts of data available to process. This allows them to identify leaks as small as 1/16″ (2 liters/minute) with a very high degree of certainty and virtually without false positives. The wealth of data, allows the algorithms to identify the existence of leaks without being misled by non-leak disturbances such as artifacts and environmental noise.


Broadband 3G Cellular Communication and GPS synchronization

All communication is handled by built-in broadband 3G GSM technology. Every sensor contains a 3G cellular transmitter and GPS receiver. This has substantial impact in the following ways:

  1. Large quantities of data can be sent to the analysis engine, containing the complete range of frequencies collected by the sensor.
  2. Sub-millisecond GPS-controlled time synchronization, ensuring high correlation accuracy.
  3. Easy and rapid deployment requiring no external aerials, no RF repeaters or concentrators, no licensing issues and no installation on streetlamps. AQS sensors are simply attached to hydrants or pipes every 1000-1500 feet above or below ground, with no additional components.
  4. Long battery life is achieved by an advanced power-effective design, which has been tested to last over 5 years in standard operating conditions.


Web-Browser-Based Graphic Dashboard

The AQS graphic dashboard integrated with municipal maps is the water engineer’s decision center. The results of all the signals received and processed are presented in a clear visual manner with actionable advice and they constitute an online decision support platform for the handling of water leaks in the network.
