2. Increases the total quantity of potable water supply required, thereby
increasing annual treatment costs.
3. Requires reconnection of all existing services.
4. Increase the initial capital costs of improvements.

4.1.3 Sub-Alternates. Additional sub-alternatives were considered under the
two basic alternate plans including the purchase of a supplemental water supply
from the Southeastern Colorado Water Conservancy District via the proposed Arkansas
Valley Conduit. An update on the status of the Arkansas Valley Conduit project
was received from the Water Conservancy District. Apparently the project is still
in the planning stages and is contingent on a number of items including favorable
action from Washington. Scheduling of construction of the pipeline has not been
established (even tentatively) at this time. At best, the realization of a treated
water supply delivered to the town of Swink from the Arkansas Valley conduit is
many years in the future. Consideration can be given for utilizing this supply
source as a supplemental water supply only for later stages of development. Initial
improvements must be based on the town's existing water supplies.

The various costs of the alternate selected is summarized later in this report.
Based on the advantages and disadvantages listed for the two basic alternatives,
the estimated costs for operation and maintenance, and reliability of the system,
Alternate No. 1 is selected as the plan to be developed.

4.2 PHYSICAL PLAN

Having laid a foundation of population growth, status of existing facilities, and
a projection of present and future water requirements, a plan is hereafter evolved
to expand the existing facilities in stages to meet these requirements.

4.2.1 Distribution System. A major improvement project is necessary at the
present time to correct deficiencies and maintenance problems in the existing
system and to provide required fire flows to all parts of town. Once an adequate
base system is constructed, it can be extended in short segments as the need occurs.
As growth occurs andr:lhe landis:developed,:the_Town"should:requirerthe'owner" or
developer of the property to install an adequate distribution system at no cost
or little cost to the Town. When examining a proposed extension plan it must be
kept in mind that the developer must not only provide a distribution system and
fire flow to his "development,: but the mains must be adequately sized:to extend
beyond his immediate development and provide fire flows to the property beyond.

Proposed improvements to the potable water distribution system are shown on
Plate II. Proposed improvements to the non-potable distribution system are shown
on Plate III.

Figure I shows the total design area to be considered up to year 2020 and Figure
III shows the major distribution main gridwork necessary to deliver fire flows to
the design area. While the gridwork can be constructed on a piecemeal basis, the
grid must be completed and the loops closed in order to deliver the required flows.

The design area shown on Figure I encompasses approximately 640 acres. It is es-
timated that approximately 100 acres of this total will be included in railroad,
school, highway, and other public lands. The remaining 540 acres would be utilized
for residential and commercial development. At the design population of 1664
(median projection for year 2020) this would be an average population density of
3.1 persons per acre. This results in an extremely low population density and the
design area will be roughly 1/2 developed at the design population of 1664.
Population density within the existing Town is approximately 5.5 persons per acre
and include numerous vacant lots. Using the high population projection for the
