Water services asset management: an international perspective

Abstract

This paper illustrates how the development of asset management for water utilities across the globe has been initiated by recognition of the need to maintain the assets and levels of service at an economic cost and develop sound accounting practices. In the UK, consolidation of water services and developments in sewer surveying and computer modelling were key factors in the early growth of asset management. The paper goes on to draw lessons from the past 30 years in quantifying water utility assets, assessing their condition and performance and developing business plans, with the aim of providing a satisfactory level of service at an economic cost. The impact of privatisation on water services in England and Wales and of economic regulation across the UK are considered in relation to the development of asset management, capital investment, levels of service, customers and charges.
