WATER DEPARTMENT NEEDS
Detailed Report of Expert Installa-,
tion of recommendations Would /
Cost Over sS2,000. +

engineer, who has examined our wat
er supply system, and which we were
unable to present in our last issue, is
here given in considerable detail. 1t
will be remembered that this report
was read at the last meeting of Coun-
Gil, and the recommendations given
below are worthy of much thought.
Should they be adopted, the cost to the
city would be s82,612, not including
the cost of minor changes and addi-
tions for which no estimates are given
What improvements or changes as
outlined in this report will be made,
is something which Council alone will
decide. so the report of the Water
committee, perhaps, at the next meet
ing of Council, on these recommends
tions, will be received with consider
able interest.
The substance of the report, con-
densed in some instances is as fol-
lows:
The general plan adopted in the
original construction of the plant was
well proportioned to the condition
then extant with population of
about 5000, and to such extensions
as should be required for the usual
developments of % years thereafter.
which period, 1SS6-1911, has just now
elapsed
With the necessary extensions and
improvements the works can be made
to meet all present and future re-
quirements for another 25 years,
which period is in accordance with a
well-established rule for economical
immediate expenditure on public
works expected to develop.
The low-season flow of Mantua
Creek is sufficient to supply, at the
present per capita rate of consump-
ton, population of II thousand; with
the elimination of waste and the in
PRODUCTION of storage reservoirs, will
amply supply the city when its popu-
lation reaches 40 thousand.
The analyses of the water indicate
some contamination, but only such as
stream draining a territory almost
entirely occupied by farms and in
eluding drainage from several villages
The drainage of Mantua Greek, as
are most surface supplies, is subject
to the possibility OF instant and dam
gerous contamination.
The citizens of Woodbury. are GER
tainly entitled to the protection that
will be afforded by the introduction
of an efficient filter plant
PUMPING STATION.
The boilers are in need of minor
repairs, but are in fairly good condi-
tion.
The Worthington pumping engine
needs some oyerhauling, but should
not be considered an alternate unit,
on account of its low efficiency.
The r. d. Wood pump is a modern
pump in all respects and is in good
condition, but needs ordinary repairs.
TIL auxiliaries are all in good con-
dition
The boiler and engine house is ex-
posed to great danger of destruction
by fire by the proximity of the frame
structures surrounding it; by unpro-
tected opening in the exposed walls
and by the oil lamps which are used
for lighting. No fire hose and appara-
tus for fire protection are at hand at
the pumping station.
PUMPING MAIN.
The present u inch pumping main
is entirely too small to economically
convey the discharge, when running
at full capacity, of the large pumps
two and a half million gallons per "a
hours-which service involves a velo-
city of 5 feet per second, greatly ex-
ceeding the safe maximum, and in
creasing the friction head beyond the
strength of the pipe line Conse-
quently, it is necessary to reduce the
pumpage to conform to the safe car
rying capacity of the main, 1-2 mill
lion gallons per "a hours.
Running at this low rate, through
a 10 inch pipe, the friction head would
be 20 pounds per so. inch, but, on ae-
count of the corroded interior of the
present main. the actual friction head
is so pounds per So inch, and, adding
this TO the static pressure, we have
the present total working head of S5
pounds per SO. inch.
If the strength Of the main would
safely admit of running the pump at
its full capacity, the friction head
through new - inch pipe would be
81 pounds per So. inch, but the actual
loss, due to the said corrosion of the
inside of the pumping main, is go
pounds per SO. in, and the working
head 1876 pounds; or double the pres
sure which should be considered in
good practice under the existing con-
ditions at Woodbury.. The laying of
a 16-inch main would reduce the work
ing pressure about SO per cent
The supply is wholly dependent on
this single main. In case of serious
break, the city would be without wat
er until repairs could be made and the
system again filled to operating ca
pacity.
DISTRIBUTING RESERVOIR
The distributing reservoir is located
on the highest point of land available
for the purpose in the vicinity of
Woodbury. and without friction loss
