In order to provide drinking water as part of its 50-year plan, a west coast city is considering constructing a pipeline for importing water from a nearby community that has a plentiful supply of brackish ground water. A full-sized pipeline can be constructed at a cost of $122 million now. Alternatively, a smaller pipeline can be constructed now for $80 million and enlarged 20 years from now for another $100 million. The pumping cost will be $25,000 per year higher for the smaller pipeline during the first 20 years, but will be approximately the same thereafter.
