The problemThe problemLoss of water due to leaky mains pipes

Reasons:1) Old and poorly constructed pipelines.2) Inadequate corrosion protection.3) Poorly maintained valves.4) Mechanical damage.5) Amplification of pressure.

Water loss informationWater loss information

Examples of water loss worldwide :

1) London – 1000 million liters per day (nearly 50%).(Enough to fill 17 Olympic sized swimming pools every hour)2) New York City - nearly 15% loss3) Boston – nearly 36% loss4) Mexico City – nearly 32% loss5) Montreal - nearly 40% loss6) Seoul – nearly 35% loss7) Ukraine cities – nearly 30% loss8) Vietnam cities – nearly 50% loss

The solution - LDAUThe solution - LDAUThe LDAU is a light weight and cost effective LeakageData Acquisition Unit developed using the ExorBluepatented technology for current measurements.

The LDAU provides with a simple and quality assured, theassessing aspects of the leakages locations in water pipes.
