The plot is shown on Exhibit Number Nine at the back of the report. The projected annual increase in costs is equal to $11,000, which is the same as the average that has been experienced over the last eight years. PAST PUMPING COSTS Pumping costs that have been incurred over the last 13 years are shown in the following table. 14
