TPN=Total Potable Water for year N.

WHOLEN= Wholesale of water for year N.
This is by far the easiest and least subjective area of contract performance. In fact, as a baseline, the 2001 Unaccounted-for Water report was attached to the Service Contract. The following results have been calculated using the results from the City’s reports (see the 1999-2004 Stockton Public Water System Statistics in the Appendix) and OMI’s monthly reports.
Under municipal operation, from 1999 to 2002, using the 2001 format presented in the Service Contract, the UAC has had a range of 2.65% to 3.95%. OMI assumed modified operations on February 2003 and formal operations August 1, 2003.
Calendar year 2003 UAC is 7.48%.
Calendar year 2004 UAC was 6.63%.
Every year the City is required to submit, and sign, a report, to the California Department of Water Resources, entitled Public Water System Statistics. According to this report for the seven calendar years of municipal operation, immediately preceding implementation of the Service Contract (ending with calendar year 2002), the average annual unaccounted-for-water was:
