Notes: The case can be used to show how environmental aspects have not been costed
The complete case study, of which this is a part, was adapted by Somluckrat Grandstaff from materials prepared by Beta Balagot, and may be found in Dixon and Hufschmidt (1986). It presents the analysis of the cost-effectiveness of various options for disposing of wastewater from a geothermal power plant built on the island of Leyte in the Philippines. The decision to build the power plant and to tap the local geothermal energy had already been made; it was necessary to decide which means of wastewater disposal from the plant would protect the environment in the most cost-effective manner.
Seven ways of disposing of wastewater are considered in the full case study; the costs of building and operating each are different and each has a different effect on the environment. The analysis examines each option in turn, determining its monetary values and, where possible, its environmental effect.
Not all of the effects on the environment can be quantified and given a monetary value, but those which cannot be quantified should not be
