City of Santa Ana, CA I SEWER RATE STUDY
<br />These inspection and replacement assignments were then adjusted over a five year plan to moderate
<br />annual budgeting expenditures. Total inspection and replacement percentages follow those of the
<br />strategy group recommendations. Table C 4 below presents initial annual inspection and replacement
<br />assumption plans. The inspection plan percentage values indicate the percent of uninspected pipes that
<br />remain to be inspected at that time. It assumes that all pipe segments have already been recently
<br />inspected or will be under this inspection program. Percentages are the suggested replacement
<br />quantities as presented in the R &R summarizations and recommendations table presented above.

<br />Based on the above assumption plan, an annual inspection and replacement budget was developed.
<br />Table C 5 presents the resulting annual budget. Figure C 5 presents these results graphically. The overall
<br />assumption plans can be adjusted to create a variety of budgeting scenarios. Note, the City may wish to
<br />also include a nominal annual budget for ongoing inspections to address system -wide pipe segments not
<br />included in this suggested plan.
