O. WfILf'S REPORT
On Water Problem to the
Mayor 'and Council.
CONSIDERS ONLY Mill CREEK
His Cheapest Plan Would Cost the
City Nearly 100000 and costIiest
Over $225,0o0.

In order that all readers of the
Statesman may have the benefit OF
the recommendation on a gravity
water system made to the city council
by Hydraulic Engineer Otto Weile,
his report is given today in full. 1t is
as follows:
Walla Walla Wash, Sept. %, 1903.
To the Hon. Mayor and Members of
the City Council, Walla Walla,
Washington:
| Gentlemen: In accordance with
your request l have the honor to sub
nit the following report concerning
a system of water works for the city
Of Walla Walla, Washington. The
governing and qualifying conditions
are that the system shall be gravity
system having ample supply of good
wholesome water.
Area Of Population.
The area Of the city proper, which
must be considered in plan of water
works. is about 1900 acres, very near
| ly divided into two equal parts by
Mill creek.
The density of population varies in
cities from 30 to ST per acre. 1t is
safe to estimate that when the pres
ent area of the city is fully built up,
! it will have a population OF not over
! 50 per acre, as the improved means
OF transportation must hereafter pre-
vent overcrowding in cities capable
Of such indefinite territorial extension
as Walla Walla.
At 80 Der acre, the population with
in the present city limits will be Co.,
900 to 10000.
The present population is 10000;
ii is usual to assume Gin the west)
that the population of growing town
will double in 10 years. 1t would then
be necessary in the case Of WalIa
WaIla to provide for a future popula-
ton if $4,000.
Water Supply.
AS a first consideration an abso-
lutely pure supply should be obtained,
and second such supply should be am
pie, not on'y for the present but for
the future needs Of the city, ana
third. the system should be laid out
on such a generous plan that all the
inhabitants may have the use of the
water.
In fixing upon a per capita daily
rate Of consumption Of water, all in
dicatiOns cause a belief that Walla
WalIa will use more water than most
cities. The climate is hot and dry.
hence much water will be required for
personal comfort and cleanliness anu
for sprinkling lawns, gardens and
streets.
The per capita daily water cosump-
ton in the cities Of the United
States varies from about 40 gallons,
in small, economical cities, to over
200 in some of the larger ones where
no effort is made to restrict waste.
Generally a greater quantity of water
per capita is legitimately used in
large cities than in small ones, and
the tendency # the times is to recOg-
nize this as a fact and to make larger
percapita allowances for these than
has been the practice in years gone
by. While it is proper to design The
works for a comparatively large per
capita consumption, in order that they
may re large enough to satisfy the
conditions existing AZ the time Of
construction it is advisable to call
your attention. that such large allow
anceS are not necessary to satisfy all
legitimate uses. and that the greatest
effort should be made to gradually re-
| duce the per capita allowances by the
Introduction of meters, or other
mean; as by such expedients the
works may be made to supply much
| larger population. and hence the day
when extensions become necessary
may be postponed to more remote
period
The actual needs of a family of
| five has been placed as follows:
Gals.
For bathing Observation-Disclosures. 30
/ For drinking. $500. ......... D
For cooking ................... 10
For laundry and dish washing. -. 80
For sprinkling 100
