Question

In a developing country, two alternatives are under consideration for delivering water fiom a mountainous area to an arid area in the country's southern region. A coated heavy- gauge plastie pipeline can be installed, with pumps spaced appropriately along the pipeline. Alternatively, canal can be built; however, it will have greater water loss than the pipeline, due to evaporation and poaching along the canal route. To compensate for the water loss, the canal will have a greater carrying capacity than the pipeline. It is estimated it will cost $125 million to install the pipeline. Major replacements are planned every 15 years at the cost of $10 million. Pumping and other annual operating and maintenance costs are estimated to be $5 million. The canal will cost $200 million to construct; its annual operating and maintenance costs are anticipated to be S1 million. Major upgrades of the canal are anticipated every 10 years, at the cost of $5 million. Based on a 5 percent (5 %) MARR and an infinitely long planning horizon, which alternative has the lowest capitalized cost?
