4.1 BASIC ALTERNATIVES

I

In developing the plan of improvements, two basic alternatives were considered.
These basic alternatives along with some of the advantages and disadvantages of
each alternative is shown below.

I

4.1.1 Alternative No.1; Maintain dual system; Continue production and
distribution of both potable and non-potable water. Provide improvements primarily
to the potable water system to meet projected water use requirements and fire flow
demand.

I

Advantages:

I

1. Utilizes more of the existing water works, facilities. Requires little
change in the existing non-potable water system and concentrates im-
provements. on the potable water system.
2. Reduces total quantity of potable water supply required , thereby reducing
annual treatment costs.
3. Reduces initial capital costs of improvements.
4. Allows flexibility to convert to a single system at a later date if
additional potable water supplies become available.
5. Does not require reconnection of many of the existing services.

I

I

Disadvantages:

I

1. Increases long term operation and maintenance cost due to operating two
distribution systems.
2. Increases new housing construction costs by having to install separate
plumbing systems. ' ,
3. Does not correct low pressure problems on the non-potable water system.
4. Increases cost of distribution system extensions due to having to extend
two systems.

I

4.1.2 Alternative No.2; Abandon the dual system concept; use existing well
supplies and build treatment, storage, and distribution facilities adequate to meet
the projected total water use requirements and fire flow demand.

I

Advantages:

I

1. Consolidates the system into a more conventional type system which is easier
and more economical to operate and maintain on a long term basis.
2. Distribution system can be extended at a later date more economically than
Alternate ill.
3. Decreases new housing construction costs by having to install one plumbing
system.
4. Corrects the low pressure problems existing on the non-potable water system.

I

I

Disadvantages:

1. Requires abandonment or major modifications to the existing treatment,
storage and distribution facilities.
