Abstract:

Cost effectiveness analysis is a useful tool for comparing water and sanitation infrasfructure options. This method was used to compare a range of sanitation options for the rapidly developing area of South Can Tho in Vietnam. The costs of cenfralised, semi-cenfralised and decenfralised sewer systems were analysed along with several different freatment and sfream separation technologies. The process of estimating and modelling costs can be challenging as considerable data is required, however, by using a variety of cost estimation methods it was possible to undertake a detailed costing assessment to compare very different infrasfructure options over their lifetimes and with reference to the service they provide. The results, which detail net present values and levelised costs in addition to a range of financial perspectives can provide a valuable basis for decision making.
