Not by uny mean th leat of Pen
dleton' many aiwet.1 In her water sys
tem. For a little more than two years
now J'endletonlans have been drinking
water brought a distance of more
than seventeen mllea from mountain
uprlngn IJke all good things such a
Aupply was secured only after a lon,
hard fight but that It was a fight well
worth while none will now deny, not
even those who fought the project re
lentleealy.
Bven In the hottest period of um
mer, Pendleton'a mounWn water to
to cold that no Iclnr la required to
make It drinkable. In quality It la not
even surpassed by the famous Bull
Hun water of Portland. In quantity
there la enough for Pendleton's need
for years to coma In purity It Is be
yond reproach. Year after year
.hemista have analysed It and declar
ed It free from any harmful bacteria,.
and rendleton's physicians will fur
nish testimony that the health of the
city has been markedly Improved
nine tbc mountain water was brought
to town. Typhoid fever baa been al
most unknown here during tht past
two years and auch few ca.ea aa have
beca reported have oecn truced di
rectly to the lire of well water or to
ot-f-town origin. Bowel Intoxica
tion among children, which was so
pwalont when the city used river wa
tsr la seldom heard of now.
8"h city not only furnishes water to
bar Inlia.ntunU but slo supplies the
Rowtern Oregon State Hospital with
water for domestic purposes. In fact
Pendleton's promise to build a grav
ity water line was one of the big fac
tors In determining the location of
that institution. The fulfillment of
that promise Is an argument of some
weight in the campaign for locating
a normal school In this city.
First steps toward securing a grav
ity system for Pendleton were taken
about seven years o. The people
wanted It and, when the aubject was
submitted to them for approval, thev
voted a bond Issue by a big majority.
At several subsequent elections, when
the gr8-11' ay'1" wa an lue, they
repeated their approval.
Hefore all obstacles were cleared
away, the water commission and In
supporters had to fluht many battle
The Indians upon whose ground were
I located the fissure springs and over
; whose land the pipe line must pa.-,
opposed the efforts to secure the land
even though generous offers were
made. It was nectv-nary to fight the
; matter through the courts.
Sell'Uih interests in Pendleton, some
lew citizens generally opposed to pro
gress and others who favored other
bources of supply fought the plans of
; the commission at every , turn. The
story of the long fteht, of the methods
employed to obstruct the efforts of
the commission, would be a long but
very interesting one.
The main source of supply for the
system Is a series of springs known
as the Thorn Hollow spring and lying
about eighteen miles east of Penlle-
ton. The principal spring now being,
ured. is the Wenljc spring The(
springs now tapped furnish plenty or
water, the minimum 24 hour flow
during the pa-st summer having been
2.400.000 gallons. Anticipating the
growth of Pendleton, a survey is now,
being made to the Chapllsh springs
about three miles beyond the Wenlx
springs nd the pipe line will prob
ably be extended there next year.
This will give an additional 1,600.
000 gallons daily. The pipe line is
sufficiently large to carry 6.000.00U:
gallons of daily dally and thbj will be!
sufficient for the needs of Pendleton j
for many, years to come.
The system was built with an eyej
to the future. In fact the present;
pipe line Is Just the fir.-t unit of the
ultimate pipe line. When the water
consumption of Pendleton becomes so
large that the springs can no longer
supply enough, the pipe line will be
extended due east to the north fork
of the 1'mntilla river, which is In the
mtiunta;n and which runs pure, cold
water. Here also an electrical power
may be generated in case Pendleton
should ever undertake to supply the
city with municipally owned "Juice."
The construction work on the grav
ity project was ucUir11 undertaken
Septemler 23. 1913. The general
contract for the construction of the
pipe line-was secured by the lient
Construction t'o. of Los Angeles and
the contracts for building the reser
voirs and constructing the conduit

along the bluffs at Thorn Hollow were
let to Jeffrey & Bufton of Portland.
The, reservoirs were completed about
April 15th. 1914. Bach reservoir has
a capacity of one million gallons and
they are arranged so one may be used
while the other reservoir la being
cleaned or repaired. Through the uaei
of a pass the water from the springs'
may be turned directly Into the dis
tributing system without going
l i
through the reservoirs at all. Thla ar"j
I rungement insures a cooler supply ofj
! water during the summer months and:
j at the same time is protection against
Inconvenience should the reservoirs'
ever hecome disabled.
! The system is very favorably built!
j in that the operation w ill require
i practically no expense as the flow of
j water Into the pipe line Is adjusted
j automatically at the tank house at the,
! upper end of the line.
j The pipe line Is of concrete and
'reinforced concrete. For a distance!
of 35.000 feel a 24 inch pipe Is used.i
1 while for a distance of 17.675 feet a'
j 20 inch pipe is in use. At other points
'the size of the line varies from IS
Inches to H Inchest The conduit
along the bluff at Thorn Hollow Is 14
inches reinforced. The siphons are
also reinforced and there is a total
of 17.655 feet of J4 Inch reinforced
pipe line in the siphons. In the con
struction of the line IS tons of rein
forcement steel was used and 40,004
barrels of cement
Along the bluffs below Thorn Hol
low there are three different tunnels
averaging- about 100 reet In length. A
view of one of the tunnels Is shown
above. There are four concrete tres
tles on the line. The siphons vary
from a 15 foot to a foot hydraulic
head. In the building of the water
system there was excavation work to
the extent of 5J.00O cubic yards. Al
ong the line there are Jg manholes at
distances of half a mile apart. The
drop on the pipe line Is one Inch to
the 100 feet for the first six miles ot
the line and for the last It miles the
fall is more abrupt, tsere being a to
tal fall of !00 feet between the tank
house and the reservoirs to the cen
ter of the city Is 25 feet The pres
sure In the central portion of town, Im
110 pounds.
The overflow from the system la
used to supply the public natatortum
with water.
