The town of Dry Hole needs an additional supply of water from Duck Creek. The town engineer has selected three plans for comparison using the incremental analysis and present worth method. The gravity plan would divert water at a point ten miles from Duck Creek and carry it through a pipeline by gravity to the town. Another system in consideration uses a pumping station that would divert water at a point closer to town and pump it to the individual households and farms. The pumping plant would be built in two stages, with a great portion of its capacity installed initially and the remaining installed ten years later which resulted to the significant projected change in annual power cost over. A utilities company across town is also proposing that they can supply water to Dry Hole but will require an initial investment for setting-up the piping system, but it takes off the burden of the operation and maintenance of the system. The engineer has assumed that each plan will last 40 years and be worthless at the end of its life. Using the data presented below and an MARR of 8%, which plan should be pursued?Perform an incremental analysis table from knowledge in engineering economy.1.) ?Initial Investment 2.) ?Completion Cost in the 10th year 3.) ?Annual Operating and Maintenance Cost 5.) ?
