age disposal system for the ayeras

The question may BE- asked Why 70

system on the average farm In reply
10 this. II is only necessary 10 say hat

The syE'em in question Is designed
10 care for ten people and consists q
two snt!ireez'ng hoppers OF toilets,
about two hundred and siIty feet Of
siKinch yitrined sewer pipe and a
dark. air tight concrete tank. this La.
ter being known as septic tank The
water for flushing the tOilcts and TIL
'ystem when necessary 5 carried 10
tho spot by a three quarter inch gal
vRniIed pipe from the college main.
As the toilets are used In an out.
house, which has no heat. they are
made frost proof or anti-freeIing
This desirable arrangement is brought
about by the water storage tank over
the hopper or toilet being flled while
the hopper Ia being used and II Pushes
automatically Immediately tho seat Of
the hopper rises.
Tho eIcreta or sewage, after leaving
the toilets. is conveyed through the
siI-inch pipe TO the septic tank. This
pipe was laid in carefully graded
ditch, and owing to the lay OF the land
two grades were necessary eight feet
being on 10 per cent grade and ono
hundred and twenty feet was laid on
~ per cent grade.
The septic tank, which receives the
sewage. is made OF a mixture OF one
part Of cement, two parts OF sand and
four partsof gravel. The top. sides and
A. .Ny4R gsH
steel rods The tank has two com.
pArtmons or chambers: one Of which
IA the settling section and the other
the discharge section. The sewage
Ia descharged into. settled and parti
ally purified In the settling chamber
Il slowly seeps around the battle
boards over tho concrete partition
wall into the discharge chamber and
whom sufficient has collected IN tn!
chamber, II IL intermittingly dls
charged from this chamber by an auto.
mRtio siphon.
This septic tank has capacity TO
take care OF the flushlngs OF forty ga
Ions per person and to discharge n,
Intervals between twelve and twenty
four hours, There Is no advantage In
having a tank larger than necessary to
properly perform the work for thtu
the liquid sewage remains too loua
and putrefaction Is likely to occur II
the siphon fails TO discharge during
the proper working periods. owing To
not having received sufficient sewage
flush suffieient water through the toll.
cts to make It do so.
The most difficult portion OF tho
system TO construct was tho septic
tank. owing to the steel rc,nfarcinr
rods. The forming was Of pine, ono
inch stun. six inches wide and dressed
both sides. while the hracing was two
by four stun The top Of the tank is
not separate from the sides, but is
nodded with the sides and ends Time
| consumed IN completing tank by three
laborers, carpenter and helper was
four and one half days and the cost,
complete. was $50 10
