Ice pigging and iDroloc leak detection from Aqualogy offer an alternative to conventional pipeline cleaning and assessment methods. Ice pigging uses an ice slurry, forced by pressure to remove sediment built up inside pipes. Ice pigging can be used with any pipe material. iDroloc uses tracer gases to prevent interruption to the water service and can be applied to detect leaks in large-diameter mainlines, small distribution pipes or connections within an urban area. The robotic system is designed to work with helium, which naturally rises to the surface and is easily detected. www.aqualogyuk.com.
