This situation can be dealt with by drilling a new well at a cost of $1,000,000 or by installing a tank and self-cleaning screen ahead of the desalting equipment. The tank and screen will cost $230,000 to install and $61,000 per year to operate and maintain. A new well will have a pump that is more efficient than the old one, and it will require almost no maintenance, so its operating cost will be only $18,000 per year. If the  s are estimated at 10% of the first cost, use a present worth relation to (a) Calculate the incremental rate of return (b) Determine which alternative is better at a   of 6% per year over a 20-year study period.<\/td>\n<\/tr>\n<tr>\n<th>Subject<\/th>\n<td>business-economics<\/td>\n<\/tr>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p>Question<br \/>\nAs groundwater wells age, they sometimes begin to pump sand (and they become known as &#8220;sanders&#8221;), and this can cause damage to downstream desalting equipment.
