16-24 The Highridge Water District needs an additional supply of water from Steep Creek. The engineer has selected two plans for comparison: Gravity plan: Divert water at a point ten miles up Steep Creek and carry it through a pipeline by gravity. Pumping plan: Divert water at a point near the district and pump it through two miles of pipeline. The pumping plant can be built in two stages, half now and half ten years hence. Alternative Gravity Pumping Initial investment 2,500,000 1,250,000 Investment at end of year 10 O&M cost/year Average annual power cost: 150,000 12,500 20,000 Years 1-10 40,000 Years 11-35 75,000 Annual benefits for each alternative are $190,000/year. Analysis period is 35 years. Disregard residual values. Choose between these alternatives using conventional benefit-cost analysis. Doing nothing is not an option here.

8. (10%) Two pumps are being considered for service in Africa. Each can draw water from a depth of 50 meters and both pumps deliver 60 horsepower (output) to the pumping operation. One of the pumps must be selected. It is expected that the pump will be in use 800 hours per year and electricity costs $0.14 per kilowatt-hour. The following data are available. Recall that 1 hp = 0.746 kW. Capital investment Electrical efficiency Annual maintenance cost Useful life Pump A $2,400 0.92 $320 3 years Pump B $2,000 0.80 $200 6 years The MARR is 15% per year. Determine which alternative should be selected if the repeatability assumption applies.
