ENGINEER NEVBERY'S SEWER PLAN.
IndOrsed by Prominent Hydraulic
and Civil Engineer.
he Says 1t is Specially Adapted to the
Needs and Location of the City
of Sacramento.

Learning that w. w. Waggoner. an
experienced civil engireer and United
States Deputy Mineral Surveyor, was IN
the city recently and had inspected Mr..
Newbery's plan for improving our sew
erage system, a RECORD UNION reporter
yesterday asked Chairman Lawton OF the
City Trustees if he had received any
word from him on the subject.
"Yes,u replied Mr.. Lawton. "to-day /
received letter from Mr.. Waggoner,
which you may read.'
Being permitted to make copy of the
letter, it is here given in full. Engineer
Waggoner has the reputation of being
excellent authority in such matters.
SAYS 1T Is EXCELLENT.
NEVADA CITY, Cal, May l, 1894.
Hon w. D. LdaCto7l, Chairman Board
OF Trustees City Of Sdcrdnaento-S!R
When in Sacramento l was requested by
some of your citizens interested IN your
new sewerage plans TO examine the plans
proposed by Mr.. Newbery, and by your
courtesy was enabled TO examine MS
maps, specifications, etc.
/ find his plan meets the requirements
for thorough, cheap and effective sys-
tenn of sewerage, and solves the supposed
difficult problem ct your city. The re-
qnirements for good sewerage scheme
are:
First-A main artery or arteries follow
ing the line of lowest depression, which
shall receive the sewage from laterals
distributed through the streets and con-
veying the same to central station. The
sewers should have uniform and as
great grade as the topography OF the
land will admit.

should be provided, that no accumula-
tions of fecal matter can occur.
Third-From the central station the
sewage should be discharged into some
large water-course or carried and dis
tributed over sewerage farm.
The plan proposed by Mr.. Newbery
meets the above conditions and is COM
and capability of enlargement TO meet
the wants of growing city.
He carries his main pipe up street
and utilizes the present system of sewer
age pipe, thereby effecting great saying
OF expense to the city. The means of
flushing proposed are adequate, and,
though new, offer no obstacles TO its
successful working. The plan of convey
ing the water around and at the head of
the various lateral sewers is all that can
be desired.
The water can be turned into any of the
sewers at will, thoroughly cleansing the
same, and by means of gates can be made
To follow any direction desired to the
main artery.
1t may be likened to pump lifting
water to a low head through long pipe,
or to one of the numerous pipelines for
which California is noted for conveying
water. In this case the head is supplied
by artificial means instead Of that OF po-
sition.
AS to means of caring for the sewage, a
tract of sandy land could be provided on
the east bank of the Sacramento River,
and the sewage distributed over the same,
with its attendant expense, that would
meet the approval of the most critical.
The plan of Mr.. Newbery is direct and
cheap. The objections raised would be
pertinent in pOpulous district whore
the sewage was dumped into a small
stream, but with river like the Sacra-
mento, and single town on its banks, as
in the case in point, the objection has
little weight.
AS to providing means for caring for
the storm water, as in the double sys-
tem." this would be necessary in a re-
gion of heavy precipitation and where
two or three inches Of rain falls in a
single hour, but in the arid region of the
West, where irrigation is necessary for
the fullest development of crops, it is
ridiculous. The rains reaching the sew
ers would be hardly sufficient for flush
ing purposes in any plan.
As to the objection raised to piercing
the levee, I would say that no hydraulic
engineer would worry much if he was
laying trunk in a dam twice the equiva-
lent hight of Sacramento levee.
The cost of operating system such as
proposed by Mr.. Newbery will be cheap,
single pumping station sufficing for all
purposes.
1t has been designed in the interests OF
economy potent factor in these hard
times.
Any proposition to abandon the present
lines of sewer-pipe should be carefully
scrutinized, when the fact is considered
that no adequate means of disposing oi
the sewage has been provided. Very re-
spectfully, w. w. WAGGoNER.
