Optimising asset investment definition and planning for urban water and wastewater services in low and middle income countries

摘要

In order to optimise asset investment decisions for urban water and wastewater services when there are limited financial resources, a cyclic and holistic approach to investment provision within the context of strategic asset management is needed. David C Logan and Jan G Janssens discuss the application of serviceability risk-based decisions that take into account whole-life-cost using technical and financial modelling, and how it can be rolled out for use in low and middle income countries.
