The town of Dry Gulch needs more water from Pine Creek. The town engineer has selected two plans for comparison: a gravity plan (divert water at a point 10 miles up Pine Creek and pipe it by gravity to the town) and a pumping plan (divert water at a point closer to town). The pumping plant would be built in two stages, with half-capacity installed initially and the other half installed 10 years later.
The analysis will assume a 40-year life, 10% interest, and no salvage value. Use an annual cash flow analysis to find which plan is more economical.
