The Importance of monitoring transmission mains for early stage leak detection
In May 2018 Canal de Isabel II experienced a large waterpipe burst in Madrid that left around 1M residents without water and a 20m crater that had to be filled in with concrete.
By monitoring transmission mains, emerging leaks can be tracked and repaired before they become significant failures.
With this in mind, a pilot of Syrinix PIPEMINDER-T technology was undertaken on four different sections of pipeline, two in urban and two in rural locations.
The objective of this pilot was to investigate leak detection capabilities on different pipeline dimensions and materials and in both quiet and noisy environments.
Sensors were installed on air valves in existing chambers.
Three systems were used to enable the detection range to be extended and confirm suitability for the different environments.
Leaks were simulated in blow off chambers whilst a correlation was run. (See Fig 2 & Fig 3)
A rural test was also conducted to test the limitation of inter-sensor distance and the impact of bends which reduce how far in distance acoustic noise will propagate.
The result was a positive correlation over a distance in excess of 3.3km!
