An environmental consultant is considering the installation of a water storage tank for a client. The tank is estimated to have an initial cost of $310,000, and annual maintenance costs are estimated to be $8,200 per year. As an alternative, a holding pond can be provided a short distance away at an initial cost of $210,000 for the pond plus $90,000 for pumps and piping. Annual operating and maintenance costs for the pumps and holding pond are estimated to be $10,000. The planning horizon is 20 years, and at that time, neither alternative has any salvage value. MARR is 18 %/year

What is the present worth of each alternative?

Storage tank? $_____
