OF THE CITY COUNCIL
Ian W G.. Wilson of Council Water Works
hmittee Gives Comprehensive Report
\ the Scheme. Engineers Figures
Taken as Basis for the Report

aminations and analyses of samples
Of water taken from the river at the
point near where the proposed pipe
line starts and also from the north
and south forks Of the river, as we'll
as water from the Thompson and the
Evans water system. These tests
extend .over period from May to
October. Prof. Beardsley and also
Mr.. DeBerard, chemist for the Den
yer Union Water company. made
separate tests of samples of water
furnished them from the river at the
point of the proposed intake. Each
pronounced the water distinctly
purer than the standard or average,
and Mr.. DeBerard reported that the
water is purer and softer than the
water secured by The Denver Union
Water company, after passing
through their filter beds.
George G. Anderson, who has
been employed as consulting engi-
neer, has completed his preliminary
work and filed his report, recon-
mending that the city construct 20
inch pipe line from the mouth OF the
canon, a distance of about 3S miles,
to connect with the present water
mains in the city. He also recon-
mends that a reservoir or sedimenta-
tion basin and filter basin be con-
structed near the head of the pipe
line, and also storage basin near
Greeley, all at an estimated cost OF
s3l9,S $50.
Intake and Sedimentation Basins
"He has selected for the intake a
point on the north side of the river
near the canon. From this point
the pipe extends south across the
river, a distance of about 5000 feet,
to the sedimentation basin.
1.-THE tract of land to be used for
standardization and filtration basin
is located on the south side OF
the river adjacent to the Pleasant
Valley canal, and extends from the
river bank south nearly 1000 feet
and lies between said canal and the
old railroad grade and contains an
area of about so acres. This whole
basin naturally divides into two por-
tions at narrow neck slightly over
200 feet wide and about 400 feet
from the north or river end. This
basin in order to be converted into
reservoir will require add1tlonal
banks on river side and south end,
and when completed will have
storage capacity Of about 26,5oo,oo
gallons, or a supply for eighteen
days at the present consumption.
In case the river water Is muddy by
reason of storm we can shut 1t out
of the reservoir or sedimentation ba-
sin and use the stored water until
the muddy river water clears again,
thus avoiding the flow of muddy wa
ter into the filters. The site ac-
quired is sufficient to provide sec
ond reservoir of more than three
times said capacity which can oe
constructed later If needed. water
will be taken from the sedimenta-
tion basin by pipe line on the
north side of this second reservoir
site, q distance of 2.40O feet to the
first filtration basin.
Filtration Basins.
1.-TWO filtration basins are de-
signed for ultimate constructloh'
both of the same dimensions. Inc
bottom of each will be $50 by 'oo
feet or about "a acres. IL Is
thought best to construct but one
basin at the present time, which VIII
yield about 21s or million gallons
per day. This basin will be 10 leel
deep and will be lined on the ihsioe
with concrete so as to be water tight.
On the bottom will be laid per1or-
ated pipes to collect and draw OIL the
water, and over these pipes Will oe
placed layers of gravel and sand TO a
depth of three feet, constituting the
