Much that has been written about leakage economics and strategies has been aimed at either the leakage specialist or the economic regulator. This paper aims to make the practitioner aware of the key messages from the theory, and the issues which have to be taken into account, when developing appropriate policies and practices. The tasks and solutions involved in developing a strategy are illustrated in figure 1.
Fig. 1 -A Structured Approach to Leakage ManagementThe most important aspect of any leakage strategy is the leakage target. What level of leakage should the water supplier aim for, and what level should be maintained in the longer term? In an ideal world, every water supplier would like to eliminate leakage from water distribution systems. However, there will always be a level of leakage which has to be tolerated, and which has to be managed.The paper gives an overview of the prime techniques for leakage management, which have been referred to as the four 'pillars'. Each of these follows a similar law of diminishing returns on investment to make savings in leakage. The key issues for introducing these four elements are discussed, together with the steps required to calculate the economic level of leakage.
While a myriad of factors and subtleties contributed to the credit crisis and the ensuing economic recession, certain behaviours by policymakers made it more or less inevitable that there would be a problem of sorts at some stage.On a more micro level a piecemeal system of skewed economic incentives and complacency fostered innovation at a pace and to a degree that even practitioners had little comprehension of the full implications of their actions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
