Naigatuck. Dec 1S.-Local resi-
dents will have a 100 per cent pure
water supply as the result of the
erection of a new plant, estimated
to cost about $1,000, near the high
service or Mulberry hill reservoir,
it was learned to-day. A fine
new chlorinatrng plant has been
erected there and is virtually fins
ished. The work has been done
by the Naugatuck Water company.
The plant supplies chlorine gas
to the water In the reservoir and
kills any germs which are in the
water at that time. A similar
plant has been operating at the
low service reservoir at Straits
vile, but the machinery in the
Mulberry Hill plant is different
because conditions there are the
same. The Straitsville plant
purifies about 80 per cent of the
water supply. The new plant will
take care Of the rest.
Three Rooms
The. plant, designed by Seymour
Squires, Water company engineer,
is building made of cement
blocks and has three rooms, each
with double doors, and cellar !.
An inspection of the plant by the
Democrat reporter revealed that
it is we'll equipped with delicate
machinery which has to measure
the amount of chlorine gas neces-
sary for mixing with the water
supply to a fine degree. Erection
Of the plant and the installation
of machinery has been underway
for two months and the building is
now completed. There yet only
remains installation of permanent
recording instruments before 1t will
be fully equipped. However, Mr.
Squires stated to-day that he had
worked on the plans for many
months before the structure was
started.
The Straitsville plant has a
draw" Of about two and half
million gallons a day as an aver
age, but the Mulberry Hill reser-
voir has only about 10000 gallons
of water consumed per "a hours,
AS a result only q limited amount
of chlorine gas can be mixed with
the supply, especially at night
when the amount Of water drawn
from the reservoir Is low. Because
of this special machines had to be
secured, entirely different from
those used in the low service plant.
No Windows
The three rooms in the build
ing are known as the heating
ing room, the hydraulic room and
the chlorine mixing room. One
unusual feature of the building is
that there are no windows INIT
One of the principal reasons for
this the fact that If there are no
windows there is nothing for de-
youths to destroy.
In the heating room there is a
stove which keeps the room at the
required temperature and the re-
cording Instruments will be stored
there. 1t has board walls and the
double doors in the building are
used because it will mean less
draft from outside seeping through.
Hydraulic Presses
There are two hydraulic pumps
or presses in the second room.
One could handle the entire pres
sure by itself but the second Is
in case of emergency. II the
other should fail, the second could
handle the pressure itself. As 1t
Is, they divide the pressure. The
walls of this room are plastered
and the moisture from 1t cannot
seep through into the other rooms.
In the third room, the delicate
machine which regulates and mixes
the chlorine solution is stored.
There is a tank containing 100
pounds of chlorine gas which Is IN
liquid form because of the pressure
to which 1t is subjected. This
Is connected with another tank IN
which the pressure 10 less and the
gas ii transformed there from q
LIQUID into the normal gaseous sub
stance. This in turn Is connected
with a measuring machine which
regulates the flow of. gas. This
same machine Is connected with
the water in the main which Is
kept at a 9O-p0und pressure.
