Section 4
Proposed Facilities

The capital costs assume that within 20 years, 3 additional wells will be needed at a
total cost of $5 million. Costs for these wells are distributed uniformly at
$250,OOO/year. It is also assumed that additional capital costs will accrue from the
lowering of several wells and rehabilitation of wells A-I and A-3. These costs are
included in the capital costs in 2006, 2007, 2008, and 2009. It is important to note that
assuming groundwater levels continue to decline, the expense of additional wells and
pumping could significantly increase in the long term. Given that the timing of when
additional wells would be needed is not certain; these costs are only an approximate
estimation.

Table 4-2 provides a brief qualitative summary of anticipated improvements that
includes both the planned groundwater improvements and the potential surface
water supply.
