Valuing the Costs and Benefits of Improved Wastewater Management: Part II: Economic Valuation Methodology Guidance - CEP Technical Report 93

This technical report provides a methodology for evaluating the costs and benefits of improved wastewater management in the Wider Caribbean Region, focusing on economic valuation techniques to inform decision-making. It outlines a structured three-phase approach—scoping, analysis, and outreach—to assess the impacts of wastewater investments on ecosystems, human health, and local economies. The guidance emphasizes stakeholder engagement, data collection, and the use of decision-support tools like Multi-Criteria Decision Analysis (MCDA) and Benefit-Cost Analysis (BCA) to compare infrastructure scenarios. Practical templates, such as the Characterization Form and Evaluation Matrix, are included to streamline the assessment process.
