be cleaned out by digging down and
opening up a few of the wyes at in
tervals
In the very coarse gravel in which
the water is found along the Umati-
tilla. we believe that just as good re-
suits would be secured by the use of
wells at intervals OF 100 to 200 feet and
intermediate pipe laid with tight joints
to exclude weed growth. In the event
of future developments or in case of
necessary repairs to the present lay
ont we would suggest design for n
well with concrete block curbing in
the lower porto, constructed in such
a way as to permit free in filtration of
the surrounding water. Such wells
lcould be constructed very cheaply,
and would give access to the line for
repairs which, with the elimination of
lopen joints. should be seldom neces-
sary.
Recommendations.
At the present time there is practi-
cally no data upon the hourly, daily.
or monthly use of water in the city of
Pendleton or the distribution of the
use among the different parts of the
city. The only record of consumption
/
the metered outlets, which is known |
to be only a portion of the flow which !
is brought into the city by the con-
duit. The condition is similar to that |
of merchant who conducts his busi- |
ness without accounting records, and /
we are handicapped in, formulating I
our recommendations just as an au- /
| ditor would be who is called into such /
a mercantile establishment.
We have already outlined to Mr.. |
| Hayes, city water superintendent, a I
plan for installation of weirs on the /
intake and overflow from the reser- /
voirs. These should be provided with |
recording gauges, which will furnish 1
a continuous record of the water used. 1
At the outset we do not recommend 1
any additional measuring devices on
the system, but believe that after a
couple of months record from these
weirs, giving the actual use of water
by the city, have been obtained the
losses revealed will be serious enough
to justify the installation of addition
al meters. and the tracing down and
elimination of excessive leakage in the
system. A thousand gallons of waste
| from the system which is stopped,
justifies as great an expenditure as
bringing a thousand gallons addition
al water into the reservoirs. In fact, II
the stopping of waste is of more act
ual value than additional water for
the reason that the cost of waste wa
ter is made up in part, of the cost of
the larger mains valves and laterals
which must be provided to carry it.
With view to the future develop
ment of additional supplies along the
Umatilla river, we advise the adoption
of a program of future engineering
studies, surveys, and measurements.
As we see the engineering work to be II
done, there is no occasion for the or
ganization of large party or under
taking the work on a large scale. In
fact, the work of measurement and |
keeping of records is such that it can
not be hurried. Preferably, a party |
of two or three men should be utilized
over period of year or more in the
installation of wells, measurement of
ground water flow, recording eleva-
tions. taking temperatures, and samp
ling water for chemical analysis, or
other work which may be incidental
to a thorough ground water survey of /
the Umatilla river valley.
The ultimate result to be worked for L
is a complete map and record of the Il
various ground water sources along II
the Umatilla river their physical II
characteristics. extent, and feasibility Il
of development. With such data and
knowledge of the present requirements Il
and rate of increase, the water COM
mission would be justified to make Ii
plans years in advance for bringing Ii
in of this or that spring or source of L
supply, selecting in each case, the one Ii
which is cheapest or fits in best with L
the general scheme. 1t is possible to L
measure and investigate a given sup II
ply in such a way that the flow to be II
obtained from it can be predicted with II
a reasonable certainty, and construc- IL
ton need not be undertaken in a hap III
hazard MINER, or without definite as Il
surance of results. IL
From surface observations, 1t is HI
Dur opinion that the most available IL
additional supplies for early use are L
an extension of the Chaplish Springs l=
layout and the bringing in of Squaw I=
,reek ground waters. We offer this L
Information, however, with the reser- L
yation that it may be later modified L
When actual sub-surface Investigations Il
nave been made. IL
