reservoir has been effectively settled
by the employment Of two powerful CEN
tHueui pumps possessing "a capacity
OF 5000 gallons each, minute These
pumps ute set To work pumping the
stun out Of the reservoir and forcing
the matter into the outfall sew T. INTO
the sea. If 1t should ever be desired
TO stop the flow of the stuff into the
main reservoir the gate to the one of
wells Is shut. The pumps can then
throw the stun out from the wells as
readily as from the reservoir In spite
of the fact that the pumping plant is
probably complete I'm every respect there
is danger of either of the pumps breaking
ana causing the reservoir to become
/ Hooded and the sewer back up so a safe
~ outlet has been provided. About two
hundred yards from the pump house
safety valve has been built in the
main sewer line and from this opening
will be built a line of pipe to curry the
sewerage out several hundred yards in
to the water. GraVitation is the force
upon which the engineers rely to force
the stuff from the pipes i'm case this
safety valve has ever to be utilized.
At the present time the pumping sta
ton still requires considerable work
before it will be ready for occupancy.
The roof has not even been put on and
some more machinery and connections
of pipe viii have to be made.
From the pump house runs a line of
heavy black steel pipe far into the wa
ter, completing the final section of the
sewer system. This is known as the
Outfall Sewer. According to the con-
tract this line has to be extended so
that the contents will flow into a depth
of 100 feet or a lesser dept which may
be deemed sufficient to effectually carry
the sewerage matter away The con-
/ tract for this piece is about S29. 900
| Considerable work yet remains to be
done on this section but as the bed for
| the pipe has to be drilled in the coral
and the pipe encased i'm sacks of ce-
ment the work has been necessarily
considerably delayed for in addition to
the other difficulties all of this work has
to be done in the water with the break
ers sweeping past all the time.
In fact all of the work connected with
the entire system has been delayed
Though the contracts originally called
for fines to be paid if the contractors
failed to complete their contracts at the
specified time, it is probable that much
leniency will be shown them The
plague caused a delay of six weeks in
the work and the failure of some mate
rial to arrive when calculated also con-
sumed further time.
Before the sewerage system is for
mally accepted by the government a
special test will be made of the reser-
voir for the purpose of determining
whether there is any leakage in any
portion of the sewers. They will be
watched for twenty-four hours and a
record made of the quantity of water if
any. that flows into the reservoir It
is naturally to be expected that a GER
tain amount of water will come through
with the pipes laid under sea level but
should it be of sufficient quantity as to
give rise to the belief that it is due to
any faulty construction, a fine of so
much each gallon will be charged
against the contractors. One fact must
be taken into consideration when such
test is made that if any leakage be
suspected. the entrance of the water
might not be due to any fault
of constructing the sewers but to an
entirely different agency. This agency
is the ponderous steam roller of the
street department. The earth has not
been packed down so very solidly over
many of the sewers and with a heavy
machine like the roller passing over
loosely packed earth the chances are
very strongly in favor of some of the
pipe being cracked by the strain.
F. Il. Edwards, is the resident en-
gineer. He is specially engaged by the
government to direct the construction
Of the system.
