The Guide to Economic Analysis of Water Supply Projects provides a structured framework for evaluating the economic viability of water supply projects. It focuses on assessing both the financial performance and the broader economic impacts of investments in water infrastructure. The guide outlines methods for estimating project costs, including capital and recurrent expenditures, and benefits such as improved health, time savings, increased productivity, and environmental protection. It emphasizes the use of cost-benefit analysis (CBA) and other economic appraisal techniques to inform investment decisions. The guide also provides practical approaches for incorporating uncertainties, discounting future costs and benefits, and evaluating affordability and sustainability. Designed for policymakers, engineers, and project planners, it supports effective allocation of public resources and ensures that water supply projects generate maximum economic and social returns.
