DR. FALAIGANTs sEwERAaEP PLAN

What He Has to Say in support OF It.
see that Col. Winn states that the cost
of constructing house drainage systems
under George E. Warnings supervision has
been very expensivel
Yes, it strikes me that by saving the
amounts covered by his royalties and profits
a very considerable amount of money can
be kept in our own pockets. Then again
the large amount saved in this way will
encou4 age council to practically abolish the
expensive permit system which in effect
Furnishes the house owner by making it
burdensomely expensive to do what he
ought to be encouraged to do for the gen
eral health of the city, as we'll as for his own
individual benefit. There is one
thing about the expense of construction Of
the Memphis system which does not appear
in Col. Winn's interview, viz that much of
the soil of Memphis is clay, and excavations
in clay soils are always more expensive than
those in sandy soils, unless quicksands inter
fere with work in the latter soils. ] do not
mean to say, however, that Mr.. Warings
profits on the Memphis system may not still
have been quite large. The difference in
cost under Mr.. Warnings management and
unde' local municipal management at Nor
folk is very practical illustration of how
much Savannah can save by employing her
own engineers and doing her own work.
What was your estimate, doctor, Of the
cost of the system down the lanes, as pro-
posed by you.
AS the manufacturer of the pipes stated
to me in person that he could lay the l2-
inch pipes down in Savannah at about 81
cents running foot, l made what
thought was a very liberal allowance for
excavation-that is, 10 cents per running
foot and this would leave so cents per run
ming foot for the general expense of laying
down the pipes, cementing the rings, con-
structing one manhole to each Ulock (say
about every $50 to 400 feet, and putting the
earth back again in the excavation
after the work is complete. Where
the pipes are laid at an average
depth Of feet the average excavation
would be between 2 and cubic yards for
each running yard Of pipe. The allowance
of 10 cents per running foot, which l made
for this part Of the work. would be 81 cents
per running yard, or about % cents per
cubic yard where the depth is about feet.
OF course, these figures will vary where the
sewer depths are sballower or deeper, in q
few instances deeper cuts being necessary for
some distance. If you Will take the 6gures
on the work at Norfolk, where, as
Col. Wlnn says, they had more or
less quicKsand to contend with, you
will find them wonderfully close to my
own-that is IS 900 mile is very close to
my estimate OF 81 foot; and as over the
great body of this city, between Bay and
Anderson. and between East Broad and
West Broad, our brick storm-water sewers
have extensively sub-drained the soil, our
difficulties from the presence OF quicksand
will be very materially lessened.
see, doctor, that you mention 12-inch
pipes for the lane sewers for house drain
age. Why do you select these larger size
pipesi
Wherever small pipes have been used,
whilst theoretically sufficient, they have
are plain enough. First, the theory that
none but the waters from water closets will
get into them Is altogether at fault. The
waters from bath rooms, kitchens, wash
rooms, ETC., must also and vent by this out.
