alternates. Owing to the tuberculated and deteriorated condition of the dis-
tribution system, small service lines, inadequate fire hydrants, etc., the

complete system within the Town's service area must be entirely replaced.

1. .The distribution system for the Town is relatively the same

for all five Alternates. Due to the previously described condition

of the existing system, approximately 95% of it will have to be re-

placed.. Bury depth (6'-00") will be such that freezing of the line is

prevented. Individual service lines from the property line to the resi-

dence will most probably have to be replaced as bury depth in. most in-

stances is too shallow. Meter pits and meters will be installed at the

property line on all commercial, residential and vacant lots promoting a

tap fee. The latter is proposed as it will eliminate the possibilities

of exposing and damaging the waterline for future taps.

The major arterial will be 8" diameter Class 200 PVC waterline

and the minor ones 6" diameter Class 200 PVC. Dependent on the route

chosen, a shifting in the quantities of 6" and 8" diameter pipe "ill

differ, but the overall project cost will be altered very little. Fire

hydrants will utilize National Standard threads with two 2~" diameter

feeder nozzles and one 6" diameter pumper nozzle. Looping of lines with

installation of proper valves will be engineered into the system to limit

waterline breaks or shortages to a minimal area.

Service lines to single family equivalents will be 3/4" diameter

and lines to businesses, schools, etc., sized as capacity demands. All

will require corporation stops and meter pits with appurtenances.

Normal operating pressure will be between 60 and 75 psi within the
