Tariffs and efficient performance by water suppliers: an empirical approach
2012
Water leaks are an environmental and sustainable issue as well as an economic issue. The objective of this paper is to analyse the efficiency of a sample of Spanish urban water systems by considering water leaks in a network as undesirable outputs. Data envelopment analysis (DEA), an analytical benchmarking methodology, is used to calculate technical and economic efficiency. We also discuss the possible relationship between efficiency and tariffs charged to users. Results show that the possibilities for reducing water leaks in networks are high, thus demonstrating that there is room for savings from an economic and environmental point of view. The assessment of efficiency performance could …
Economic effects of the consolidation of water utilities in Japan
2014
Water utilities are affected by economies of scale. However, in Japan most water utilities are small-scale water services. Therefore, they face enormous difficulties in terms of financial and personnel resources. To take advantage of economies of scale, the consolidation of water utilities has been promoted since 1965 by Japanese water authorities. The measure has been successful to some extent; nevertheless, consolidation has not progressed in recent years as was expected. This paper identifies the main barriers that hinder the consolidation of water utilities in Japan and describes the new promotion plan for the consolidation of water utilities developed by the Japan Water Works Associati…
Public choice of urban water service management: a multi-criteria approach
2013
Local policy makers in developed countries have to make decisions in increasingly complex scenarios. Consequently, they should use all the tools available when deciding which management option is the most suitable for urban water service, given how important that service is and the variety of criteria involved in making such a decision. This article employs ‘analytic hierarchy process’ techniques to perform an ex post analysis of the decision to transfer the management of the urban water service in Granada (in southern Spain) to a public-private partnership. The main conclusion is that the decision was rational, in that it was the best possible alternative considering the hierarchy of prefe…
