- Abstract
- A model was developed to determine how to serve an urban area with sewers using willingness to pay information. The model was applied to the case of Calamba, Philippines, for which willingness to pay data were available. A sensitivity analysis varied user fees and subsidies to assess their effects on deciding the parts of the city that should use the urban sewerage system. More realistic applications of the model were presented, where watershed boundaries and more realistic cost functions were considered. The optimization model provided a basis for using the results of willingness to pay studies for planning piped sewerage systems. In Calamba, it was necessary to convert willingness to pay data obtained for census tracts to a watershed basis. It was necessary to include street sewer costs, marginal trunk sewer costs, and marginal treatment plant costs to obtain realistic results, but, by the same token, marginal operation and maintenance costs, which were ignored, should also be included. In Calamba, it also became desirable to limit candidate zones for piped sewerage to sub-areas of the city.
