E. Evaluation and Selection of a Course of Action

Different conservation and supply augmentation options require different
levels of effort and expense. Ideally, to properly evaluate each of your
selected options, you need to consider how much water each is going to save
or provide, and how much money each is going to cost. A final list of
options can then be selected by ranking all of your options by water saved
and by cost. This allows you to eliminate the least "cost-effective"
options; that is, the ones that cost the most while saving or providing the
least amount of water.

Now, review and evaluate Worksheets 7 and 9. Based on your consideration
of cost-effectiveness and consistency with your policies (Worksheet 6),
select a final course of action.

SUMMARY

By now, you have detennined whether you have a shortage or a potential
shortage. You have developed ''most likely" and "worst case" scenarios,
which can help you meet various water shortage outcomes. You have developed
utility policies regarding appropriate ways to address water shortages. You
have also considered a wide variety of options, including conservation and
supply augmentation options. Finally, you have selected a course of action
that is tailored to your tmique circumstances. You have just completed a
major portion of your Water Shortage Response Plan.
