To the Honorable Council of the City
of Los Observation-Disclosures: In compli-
ance with your instructions of January
| 20, 1897, which are as follows: You are
instructed to prepare an approximate
estimate of the cost of a complete water
works for the entire city, using the Los
| Angeles river as a source of water sup
| ply, diverting the water therefrom at
the points indicated in your report OF
December 81, 1891 and present the same
to the city council at the earliest possi-
BILE date" have the honor to submit the
following report:
The plans and specifications and esti:-
mates accompanying this report have
been compiled mostly upon data fur
nished from the records of the city en-
gineer's Office. Some special surveys
and personal Investigations as regards
certain local conditions were deemed
necessary to supply reeded information
for the purpose OF submitting water
supply system for the city of Los Ange-
les as carefully and correctly as the
limit of time and the purposes OF pre-
| liminary plant would admit. The plans
| submitted, however, go somewhat be-
yond the scope of dealing with the prob
| lem only, but embrace number of de-
| tails of the more important and costly
| features of such a large undertaking,
alike of importance as regards the en-
gineering features as well as the NUM-
cipal advantages to be derived there
from
The plans submitted herewith, illus
trate on drawing No. l. general dis
tribution plan, showing the sources OF
supply, the storage reservoirs and pipe
systems which latter embrace almost
every street within the city limits; also
a condensed, tabulated summary OF
quantities relating to water supply,
number of pipes, etc.
On drawing No. 2 a situation plan of
the infiltration gallery of the headworks
Of the Providencia rancho, together with
detailed construction plans Of such gal
leries.
On drawing No. 3 a situation plan of
crystal springs, showing our source of
| supply at this place, together with de-
| tailed construction plan Of main condu-
its. gatehouses, pipe lines, etc.
! On drawing No. is illustrated the
general storage system located at Ely
sian park and the power plant appertain-
ing thereto.
| On drawing No a plan and profile of
| the proposed new reservoir hereinafter
| to be designated as the high level res
| ervoir.
On drawing No. is shown the pro-
posed subdivision Of the city area into
| three distinct water service systems.
| This is auxiliary to drawing No. /.
| The pipe system within the city lin
| it's. as submitted, in connection with
these general plans has been somewhat
deliberately detailed and is illustrated in
the accompanying bound volume No. Z,
| embracing on eighty section sheets, with
index maps, every pipe, fitting and spe-
| cial. together with size and length OF
such pipe lines the area Of city sections,
number of population. etc.
The calculations necessary to evolve
| this system, together with the detailed
estimates, are herewith submitted in
! books s. Q. 10, II and -. A set of speci-
ficatons is appended, which specifica-
tions, while not intending to cover every
| item which contractors will eventually
be called upon to furnish, are mainly
designed to outline in general the sew
eral features of which these works will
consist, and to indicate the standard of
all requirements connected Herewith.
| While not claiming to present to you
a perfected plan, correctly and carefully
worked out in everyone of the numer-
Gus details incident to such a large
problem, nevertheless the matter pre-
sented herein will suffice to give you a
clear idea of the problem before us,
| with the a fbat odo O nd
carried out on the line suggested, that
an abundance of wholesome, clear and
| pure water would be delivered constant
| ly in the households, together with
| liberal distribution of public fire hy-
drants under adequate pressure; and
such water supply system can be OBJ
! tanned for the estimate hereinafter sub
mitted
The plans and specifications herewith
presented should be taken as illustra-
tive of the general plan of works pro-
| posed rather than as details to be rigid
| ly followed in construction. Details
should be held subject to such correc-
tions as more careful study of each by
itself and as a part of the whole may
naturally suggest
This system is designed to embrace the
entire city of Los Angeles. including the
several new additions, and will furnish
water for domestic and fire service to
