Abstract
This report introduces a robust and comprehensive cost-benefit analysis (CBA) methodology for
evaluating nature-based solutions for wastewater treatment (NBSwt). Developed under the Horizon
project MULTISOURCE funded by the European Union, the CBA framework is designed to be highly
adaptable, catering to diverse contexts including both developed and developing countries. The
methodology employs a modular structure, incorporating generic cost and benefit functions that allow
users to tailor the analysis to local conditions and water management objectives.
The CBA accounts for a wide array of economic factors, from direct costs and returns to
externalities such as pollution contaminants. It is grounded in state-of-the-art cost and benefit transfer
models and draws from an extensive body of scientific literature. The framework will be integrated with
the MULTISOURCE Technology Selection Tool and the Planning Platform to ensure user-friendly
application and consistency.
The report also discusses the economic implications of various NBSwt systems, emphasizing the
role of land opportunity costs and the importance of context-specific assessments. It acknowledges the
limitations inherent in existing cost and benefit estimates and suggests avenues for more precise, regionspecific evaluations.
