cancel each other out with a large data set; and will be mitigated by conservative <br /> assumptions elsewhere. <br /> Even though the summer camping season is assumed to be the most intensive water <br /> generation period, meter readings were also taken by camp staff for several weeks before <br /> and several months after the camping season. <br /> Inherent Limitations in Meter Readings <br /> In addition to the analytical assumptions described above, a few other points should be <br /> considered. The readings only reflect elapsed pumping time, which means that they do <br /> not reflect any accumulated volume of water after the previous pump cycle. The cycle <br /> volumes appear to be relatively high, so at the time of any meter reading a significant <br /> volume of water could have accumulated in the tank waiting to be pumped. A reading <br /> under this condition would tend to under-represent the wastewater volume generated for <br /> the day, but would tend to correspondingly over-represent the following day's volume. <br /> For these reasons, daily flow values derived from this analysis should be evaluated in the <br /> full context of the previous day and/or next day data, rather than taken as precise 24-hour <br /> wastewater generation values. <br /> Also, since meter readings were not taken on some weekend days, weekend usages for <br /> these dates are not directly calculable. Some "Monday"readings, for example, include <br /> one"camping day"plus total weekend usage, so these multi-day values must be re- <br /> allocated in some rational manner to reasonably account for weekend activities. <br /> Detailed Analysis <br /> Exhibit #2 shows a limited data set of the nine summer camping weeks with both resident <br /> and day campers. In order to provide a rational analysis, a good estimate of the <br /> wastewater allocation is required for the skipped days. For this purpose, the following <br /> procedure was used: <br /> l. Where Saturday, Sunday, and Monday readings were recorded, the Saturday and <br /> Sunday values were used without adjustment. <br /> 2. Where a Saturday reading was recorded with no Sunday reading, the Saturday <br /> value was used without making any inference about Sunday. <br /> 3. Where a Sunday reading was recorded with no Saturday reading, the Sunday <br /> value was split evenly between Saturday and Sunday. <br /> The resulting Saturday and Sunday values were then averaged to get an "inferred"daily <br /> value of 945 gallons for a typical weekend day during this period. For a more <br /> conservative Monday allocation, the averaged weekend day value was discounted to 800 <br /> gallons; then these values were subtracted from the total Friday-to-Monday volume in <br /> order to infer the allocated Monday value. The resulting"adjusted"data set is shown in <br /> Exhibit#3. This adjusted data set was used for all further analysis. <br /> 4 <br /> 291 <br />
