A regional municipality is studying a water supply plan for its tri-city and surrounding area to the end of year 2080. To satisfy the water demand, one suggestion is to construct a pipeline from a major lake some distance away. Construction would start at the beginning of 2030 and take five years at a cost of $30 million per year. The cost of maintenance and repairs starts after completion of construction and for the first year is $3 million, increasing by 2 percent per year thereafter. At an interest rate of 6 percent, what is the present worth of this project? Assume all cash flows take place at year-end. Consider the present to be the end of 2025/beginning of 2026. Assume there is no salvage value at the end of year 2080
