RE: Water Treatment Facility

Dear Mr. Rippy:

The purpose of this letter is to provide an analysis and summary of the Town's current water
treatment capacity, as well as to outline the physical expansion capabilities of the current
treatment site to meet future demands.

As additional parts of a master plan for the entire water system, the distribution system will
be analyzed as well as a population and cash flow projection will be made to analyze the
financial abilities of the Town to provide for future expansions of the system.

This report is meant to be a working document and not an exhaustive narrative report. Basic
facts and figures will be presented and further discussed in subsequent meetings with the full
Board and the Public Works Committee. At that time, more detailed information will be
available.

General

The water treatment system consists of three components. The first is the raw water
diversion structure and presedimentation pond, the second is the raw water pipeline between
the presedimentation pond and the treatment facility, and the last is the water treatment
facility itself. Obviously, all three of these separate facilities must be able to function at a
given level of production rate, both individually and in combination with the other components,
in order for the entire treatment system to provide the necessary amount of treated water.

Each of these components will be discussed separately below, noting however, to realize that
there is an inter-relationship among all three of these components that must be considered
when an increase in the overall production rate is desired.

Current Capacities

The water treatment facility is a "packaged" plant by WaterTec Company. It has a
manufacturer's rating of 700 gallons per minute (gpm), consisting of two identical, side-by-
side 350 gpm units. The facility is typical of packaged plants which are sold by a number of
manufacturers. They are very common in the industry, especially for small municipalities and
perform generally adequately. The treatment facility is housed in a metal building. The only
significant additional facility is a c1earwell which, in turn, feeds the distribution system in Town.

Skip reports that the plant cannot generally be operated at the full rated capacity. A primary
reason for this is the effect of raw water turbidity on the plant and new regulations limiting
