Reliably assessing the cost of different sanitation solutions is a key urban planning challenge. This Practice Note from WSUP describes an Excel-based financial analysis tool which generates reliable costings of different options for achieving 100% sanitation access across low-income and non-low-income areas.
For a more in-depth look at the development of the prototype tool, how it works, its practical application in two wards of Dhaka and the results it produced, see our accompanying Topic Brief ‘Financial analysis for sanitation planning’. The Brief also addresses ways in which the tool could be improved and a discussion of the tool’s potential wider applications.
