Case Studies
Welsh Water Automated Leak Detection
The brief
Implementation
Aqualogic installed 20* aQuarius sensors within a DMZ in South Wales forming a fixed monitoring network covering 5km of mains pipe.
How it works; Once deployed on the network Each sensor ‘couples’ with another sensor when leak noise is detected, then performs a ‘correlation’. Once confidence in the leak has been established, following a sequence of correlations, a GPS location is generated. The results are presented via the cloud to a job system immediately viewable on a PC before being allocated to a pin point detection crew.
The leak can be pinpointed using mobile leak detection iQuarius, utilising an acoustic sensor and a Smartphone App. This data is logged and stored within the job system.
iQuarius can further be used to simply sweep areas allowing for all activity and POI’s to be logged and cloud stored. Leak noises can be reviewed by management or more skilled personnel, allowing for less skilled surveyors when rapid resourcing is required.
*The DMZ now has 10 sensors following optimisation, equivalent of 1 per 500m.
Key aspects
Google Maps
21st Century Technology
Leak Detection suffers from traditional attitudes, the Aquarius system is a game changing innovation bringing smart network monitoring and pinpointing leaks into the 21st century.
Maximising Workforce
iQuarius Mobile Detection uses a smartphone and is an easy to use system requiring minimal training. It monitors and maps field based activity while freeing up ‘experts’ by enabling novices.
Accuracy
Continuous pipe monitoring using acoustic sensors with high pinpoint accuracy.
Results
During the trial 7 Points of Interest (POI) have been identified by the fixed monitoring system aQuarius. Using acoustic profiling the system ranked the highest priority leaks to repair comparing displaying confidence and intensity.
The top ranked POI was then pinpointed using the iQuarius Mobile System, and leak excavated and repaired resulting in a 95% reduction in NRW. The client could then decide to repair or monitor the other leaks, offering massive cost benefits.
Within 3 days the aQuarius system had undertaken multiple night time correlations and created multiple POIs. aQuarius continues to monitor this zone looking for leak intensity changes 365 days per year. This zone had been problematic with NRW not resolved following many years of tradition resource led intervention.
