Meeker to Third; thence on Third to
Leon: and thence indirectly. to the
Garnet reservoirs would naturally be
the supply main for the high level
zone. and as previously stated. D.
inch main will have to be laid TO
take its place in giving service to the
consumers to the dividing line De-
tween the zones.
The trunk line of the low level zone
will be the 12-inch main leading from
First and Meeker to Main. and thence
along Main to Seventh.
Circulating connection between the
two zones will have to be cut by stop
valves.
It will require a small amount OF
survey work to determine the boun-
Diary between the zones.
For domestic service moderate
pressure at the street line is 80
pounds per square inch. In the busi-
ness district a pressure OF 70 POUNDS
per square inch is the lowest tnat
will provide effective hre nose
streams for moderately sized build
ings. The present working pressure
on Main street will run up to ABOUT
100 pounds. varying with the supply
and demand.
1t is reported that many leaks and
breaks develop as result OF the hish
pressures. and the condition OF tne
pipes. These expensive troubles VIII
be modified by the regulating valve
which will be moved from Fifth street
and Howard and placed at First ana
Meeker. So that the valve may be
accessible for repairs and renewal Oh
discs or parts 1t should be set III u
bye-pass. AS further measure oi
safety against water hammer tew
relief valves ought to be introduced
in the lower zone.
proposed Reservoir on Orchard Mesa
The valve OF a reservoir for stor-
age and equalization. whereby II pro-
yides for the maximum daily drarts'
and the abnormal demand created by
fire. has already been referred to. IL
delivers water for portion oil the
day at rate of flow higher than that
of the lines supply it. Its cost is
partially Offset by reduction In the
size of the supply pipe. The capacity
Of such a reservoir ought to be not
less than one days supply. say l.
250.000 gallons.
] The proposed reservoir can De puiit
at a suitable point in the vicinity Oh
the pressure tank on Orchard Mesa
1t would he an open rectangular tahk
Of concrete construction. Its cost VIII
be from SIS 900 to 100000.
Supplementary Water
II has been suggested by DR.. Miller
that the seepage water which Is CON
Quoted around the base OF Garnet
Mesa in an open ditch and goes TO
waste in the river. be partially
utilized for lawn and street sprink-
ling This is an excellent idea, ana
may be developed quite inexpensiveiy
and satisfactorily to these ends. and.
In addition for sewer flushing. II
could be conducted in light pressure
mines. Old mains which are too light
for the regular city pressnres. wheh
replaced. could be used to advantage.
| I was informed that during the
spring thaws the run-oh OF Dough
Spoon creek was sometimes as high
as 25 C. +. s. This is suggestive OF
storage. and with the conservancy
and betterment Of the supply in mind
the possibilities thereof should be
fully investigated.
| Proposed improvements
| To put the water system on a sound
operating basis the following appear
to be necessary:
| "a Make any repairs on the Dough
Spoon line that are necessary to put
II In a servicable condition. such as
closing openings in the pipe by the
introduction OF new joints, and cover
ing same: repairing stand pipes. max
ing the walls tight. putting strong
locked cover on same. and providing
an ample screened overflow: making
temporary repairs to the collecting
or gathering pipes: and clean out
small reservoir near sources of sup
