His Project to the Works
Board Today
Cost of the Proposed Auxiliary
Plant Is Estimated at
$5,50O,OOO
Would Be Finest in the World
and Do Away With the Use
of Fire Engines

of Fire Engines
MAIN FEATURES OF PROPOSED $S,-
100000 AUXILIARY WATER SYS-
TEN
Two storage reservoirs on summit OF
Twin Peaks, with a combined ca
Paetty of 100000 gallons.
Reservoir near Seveteenth and Ashbury
streets, with capacity of 100000 gal
Ions.
Reservoir on Jones street hill, between
Sacramento and Clay streets. with ca
pscity OF I,oOo.OOo gallons.
Distributing system OF pipes 10 cost 3d.
$4,000.
One hundred cIsterns distributed
throughout the city, with capacity OF
$4,000 gallons each.
Four pumpiEg stations, two for fresh
water and two for salt water.
Two nreboats.
Complete RsIephOae system connecting
all parts of the plant.
Plans for an auxiliary water system
Cor fire protection. destined according
70 experts to be the finest 7f its kind
IN the world, ard for the construction
OF which a city bond issue OF $500
coo viii be asked. viii be submitted
today 10. the board OF public works by
City Engineer Msrsden Manson. The
plans provide for protection for an
area more than twice that OF the
burned district" and for the instaHa-
tion or mains and reservoirs which
VIII supply water under such high
pressure that fire engines may be dis
pensed with. Fresh instead OF salt
water win be used. 50 as TO prevent
the destruction or goods By the cheTni-
cal action Of the latter element. For
great emergencies an additional pro-
tective system is provided by IRE
boats. which would pump salt water
into the city mains tn quantities suf-
ecient 70 control any conhsgration.
The system will be constructed or the
unit plan. whereby any portion OF the
plant put out OF order by earthquake
OF other cause would not affect the
rest of tire system.
The details OF the plan to be sub
nitted By Manson we're worked out by
Assistant Engineer II c. Connick and
Consulting Engineer 7 ". Ransom
The work was done by authority Of an
ordnance passed in January. 1907, by
the board OF supervisors.
COMMENDED BY ROBINSON
Manson viii submit with the plan
letter OF conmendstion of the scheme
from ". c. Robinson. chief engineer
- the national underwriters associs-
ton. The details OF the report were
studied BY Robinson, who is consid-
cred one Of the foremost engineering
authorities IN the United States. and
9ao reported on the plans for the
hoard Of IRE underwriters OF the Pa
-ihe. In this letter Robinson says:
ET wish 10 state my opinion that the
proposition for an auxiliary water sys-
ssm for FIRE protection in San Francisco
AZ. covered by the engineers report is
the one best suited for the present
needs OF the city-one which will prove
n lasting benefit to the community and
rhich II ef5ciently operated. viii show
Itself 10 be q wise investment IN the
punishment OF loss by FIRE and IN the
substantial recognition such curtsil-
nent must receive from the fire insur-
tnce companies doing business in San
Francisco.
Continuing. the report says:
The protected area lies on the east
.rly water shed OF the peninsula be-
tveen the Potrero hills and the Golden
gate. It includes the entire present
ere limits and nearly all Of the dis
rict in which shingle roofs are pro-
aibited. In extent it covers $500
tcres. about eight and two-tenths
square miles. or nearly double the
burned district
