As a result of these and other variables, two activities are recommended to substantiate
the effectiveness of particular measures:

1. Develop a pilot-scale measure to precede the development of a full-scale measure.
The pilot can represent and better characterize a larger, more expensive, full-scale
implementation of the measure. The results from the pilot project also allow for
the refmement of projections for detennining market penetration and the resultant
savings from a full-scale program.

2. Ongoing monitoring, coupled with flexibility to adjust the level of effort on a
conservation measure, are important considerations. If demands are not reduced
to the expected levels, additional effort can be put into the conservation program
or additional water supply facilities developed. Likewise, adjustments on the
level of effort for conservation measures, facilities development, can be made if
demands are less than predicted. The key is to build flexibility into a
comprehensive water management program that will balance various supply and
demand scenarios with the management tools available.

Another key to the level of success of a conservation program is the effort put into
conservation education. While this measure does not produce a separate amount of water
savings as analyzed in this report, education is a critical element to the success of all measures
and the entire conservation program.

Qualitative Evaluation Criteria

Qualitative analysis was perfonned, as shown in Table 7-2, which indicates nonmonetary
factors affecting selection of the various water conservation measures. The applied
methodology is an adaptation of methods described in the American Water Works Association
publication Water Conservation. The table lists the conservation measures in the column on the
1eftami-the -qTflilitative criteria f6r-eval1iauonaci'osf tlie tOp. - In file matriX portion of t1ie- tible;
a "+" was assigned for a positive impact, a "- " for a negative impact, and a blank space
indicates little or no impact.

This simple application of qualitative criteria is important in that it allows a more lateral
thought process for thoroughly considering the varied aspects of each measure. A description
of each qualitative criteria and examples of how they were applied in this study are provided
below.

Initial Impact on Conservers. This criteria evaluates the initial impact that
implementing the measure would have on the customer. For example, landscaping costs for
water saving landscapes are generally greater than simple turf grass, thus the table indicates a
negative impact.
