  • Tackling Non-Revenue Water by Identifying Small Leaks

    Small leaks sink big ships – the same can be said for large-diameter pipes in utility networks. While large leaks or ruptures are seen as newsworthy stories accompanied by images of water flowing down the streets; smaller leaks can often be more devastating. Left undetected, they can add up over time, contributing significantly to ...

  • Active leakage control in low pressures - It can be done!

    Leakage and PressureWater when leaving the pipe creates an ‘energy’ and it is this energy that is transferred through the water and the pipe wall by the means of acoustic sound. This acoustic sound depending on the material of the pipe work either dissipates over a long distance or is absorbed very quickly into the pipe wall. The effect being that for metallic or hard walled pipes the sound ...


  • Case study - Germany/Eislingen - Permanent leakage monitoring is the fastest way to reduce leakage

    The town of Eislingen in Southern Germany has practiced Active Leakage Control for many years with a team of two equipped with a ground microphone and correlator who drive around in a van searching for leaks. As many of the pipes are one hundred years they had a good success rate often finding leaks. With two hundred and forty kilometers in the network, there is a large area for one team to cover ...

  • Leakage–pressure relationship and leakage detection in intermittent water distribution systems

    Field investigations were conducted to identify the relationship between leakage rate and pressure in selected areas of the water distribution system of the Holy City of Makkah, Saudi Arabia. Noise correlators were used to detect leaks in areas where the water leakage exceeded 20% of the total water supplied. The leakage rate was found to be related to pressure raised to the nth power. The value ...

  • Metropolitana milanese reduces water loss on critical steel pipeline

    Assessing the condition of buried water infrastructure can yield a variety of outcomes that are difficult to predict. Sometimes, they even seem random. The common belief that the age of a pipe determines its condition is rarely correct – in many cases, a newer main can be in worse condition than one twice or three times as old. Instead, operational, environmental and installation factors ...

  • Clarifier maintenance

    Clarifiers are expensive, to buy or repair, and their downtime can be costly in fines imposed by regulatory agencies and in community ill will. Regular maintenance, an annual inspection of the mechanism and an occasional touchup of the paint or coating system are simple and inexpensive proactive steps that will usually prevent most problems. Three components of all clarifiers require maintenance: ...
