This technical working group came up with the techniques for assessment and detection of leaks, but also developed guidelines for use of units to express leakage for further comparison with other areas in the same zone, amongst zones, amongst different systems in the same city and to compare systems of different cities bringing them on a common footing. It also presents possible targeted and good practice values.
