This is a complex sustainability issue, with strong elements of risk and uncertainty, resource and ecological limits, economic constraints, the potential for conflict and an over-arching need for the community to be engaged in the decision-making process.

This decision-making process is likely to have relevance to a wide variety of other applications, in particular those relating to urban infrastructure.Integrated resource planning is used in the analysis of supply-and demand-side options for meeting the long-term supply-demand balance for water supply systems. These options can all be costed on the basis of their relative capital and …
