- Designing an Action Plan to Control Non-Revenue Water (168.38 KB, PDF file)
Michel Vermersch & Alex Rizzo discus that during the last decade, a large effort has been made by many organizations, including the IWA, to promote new concepts and methods to improving efficiency in the management of water utilities and, in particular, in the reduction of Non Revenue Water. However it clearly appears worldwide that the level of NRW is not under control in most utilities: very often it continues to increase in an apparently unavoidable way.

- Finding the Diffficult Leaks (437.06 KB, PDF file)
Today's water utility operators have a range of equipment and techniques to measure, analyse, monitor and reduce leakage and other losses in their networks.
However, there is still a big gap in the toolbox - There are always leaks that are difficult to find.
This article has a look at some of the alternative approaches to leak detection new and old

- The Repair or Replace Dilemma for Services and Mains (47.00 KB, DOC file)
In this article Jo Parker investigates the replace or repair dilemma within in the distribution system. A substantial amount of work has been carried out by the Water Loss Task Force to develop methodologies and case studies for active leakage control, pressure control and repair management. However, attention has only recently turned to the remaining method of controlling leakage – that of managing the infrastructure and in particular replacing the pipes at the end of their useful life.
