lines, eight and twelve inches respect
lively, will be carrying to capacity ev-
cry moment of the time there is wa
ter enough to keep them full may
make it unnecessary to build the pro-
posed additional flow line at present.
If this is done our present flow lines
will carry 100000 gallons every "a
hours. Though it is felt that if the
additional flow line can be built now
it will tremendously safeguard our
supply of water.
If this additional flow line is cut
out for the present, it would, of
course, reduce the total cost of. the
improvement to approximately $324,-
900.
The engineers say that if a 75,000,-
600 gallon reservoir were built instead
of one of 10000, 900, it would increase
the cost by $4,000, and hundred
million gallon reservoir would cost
$186, 900 more than the fifty million.
Water Mains Too Small
That item of $64,150 in the above
estimate is for something we have
got to have along with additional wa
ter. Our water mains have less than
half the carrying capacity prescribed
for and usually found in cities of this
size. None of our distribution pipes
are as large as they should be. On
West Railroad avenue, two blocks
from the main business section, if you
open the hydrant, the water doesn't
half fill the. opening 1t has no force.
No water pumping fire apparatus ever
made, can pump with sufficient force
to overcome the handicap existing
there by reason of the main being too
small
Flagstaff should not have any main
of less than 4-inch capacity. Yet in
most of our residence sections there
is no pressure at all at the hydrants
because the mains are 2-inch and in
few cases even less. In no case
should hydrant be on less than a
4-inch line. Many cities make the
minimum inches.
Burns & Mcdonnell report that the
poor pressure makes many of our hy-
drants practically useless and that the
entire west part of town, most or the
south part and a good deal of the
east and north parts have practically
no fire protection. Nor have we
enough hydrants. The Improvement
plan includes IA additional hydrants.
At present we have two supply
mains from the city reservoir running
down Leroux street to Railroad ave
nue.. One of these is 10 and the other
/ 6 inch. From these main feeder lines
there extend in various directions 2.2
miles of 6-iflch mains, 1.2 miles of A..
inch mains, miles of 3-inch mains,
3.5 miles of 2-inch mains, and half
mile of 1-inch mains.
Burns & Mcdonnell among other
Recommendations make and include in
their estimate: A 12-inch feeder main
down Humphrey street to Birch ave-
nue.; a 1O-inch main from Humphrey
and Birch to connect with the Leroux
street mains, an 8-inch main from
Humphrey and Birch down Humphrey
| to the electric light plant, to connect
with a 6-inch main on West Phoenix
avenue, 6-inch main from the latter
point along West Phoenix to the cor
liner Of Sycamore and Coconino; thence
north along Sycamore to Railroad
avenue, thence along Aztec to the
north city limits and back east along
| the city limits on Chautauqua avenue
Ito Park avenue; spur one block
south on Park avenue to connect with
i the Cherry avenue main; continuing
east from Park avenue on Chautauqua
with S-inch main to connect with the
| 12-inch main at Humphrey. In addi-
ton to this big loop the engineers also
recommend: A main from the present
6-inch main on Milton road east along
Clay avenue to the new mill main at
O'Leary and Brannen; a spur from
THE Clay avenue main along South Lee
roux to connect with the present s.
Inch Leroux main; spur running
across below the railroad to connect
| ing present 6-inch main on East Phoe-
mix avenue with the East Railroad
