29. 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

$426,000, and annual maintenance costs are estimated to be $6,400 per year.

As an alternative, a holding pond can be provided a short distance away at an initial cost of $180,000 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 $17,000. The planning horizon is 20 years, and at that time, neither alternative has any salvage value. Determine the preferred alternative based on a present worth analysis with a MARR of 20 percent/year.
