adequate.
In speaking Of the water supply
which is owned by the Bridgeport
Hydraulic Company the following
CONCLUSIONS.
Organization.
The works, privately owned, are
ably managed by competent employees
of an efficient and progressive com
pany. Franchise requirements bear
ing on fire protection are vague Rec
ords are reliable, complete and most
ly in convenient form
Emergency Fire Service.
The failure to respond to alarms
would be the cause of considerable
delay in rendering assistance in case
! of emergency.
Supply Works.
Sources developed provide for a
safe daily draft from gravity sources
| in excess of the present REQUIRE
ments and additional supply is pro-
posed. The works are well construct
| ed and maintained.
| The gravity distributing reservoirs
| are of large capacity, are in good
| condition, and storage is well main
| tanned from supplemental reservoirs
| Supply from each of the four ordin-
| arily used is dependent upon single
| long mains, of ample sizes for the
development and of combined capa-
| city to furnish domestic and fire sup
ply; If break in the 4s-inch main
from Hemlocks should occur at time
OF maximum consumption the availa-
BILE fire flow would be somewhat less
| than the required quantity.
| Consumption.
The rate of consumption is unnec-
essarily high, even considering the
| large manufacturing use; relatively
| few meters are in use. A low rate
| would result in increased efficiency
| or the system in maintaining good
service, deferring the time when ad.
| ditional supplies will have to be de.
| veloped, and providing larger supple.
would undoubtedly be effective ant
should be adopted and enforced.
| PreSSures.
| Pressures range from good to low
and are fairly well maintained; the
minimum occurring almost daily is ade
quate for reliable automatic sprinkle,
supply in buildings of moderate
| height.
| Protection.
Reasonable protection for the con
gested value district requires a fir,
nestle consumption of at least 10, CT,
gallons per minute; the total guam
tity includes an allowance for 1osse
| through broken connections AM
hydrants left open incidental to larg
fires, and the distribution system
should be capable of delivering tn
quantity redfuired in the district abou
any block or group of buildings O

l 70 RI a1i ~,
Upon any large fire through hos
lines, none exceeding 500 feet il
length. The manufacturing district
require from 5000 to 5000 gallon
per minute, and the minor mercan
tile and residential districts from $50
to 1000 gallons per minute.
The results obtained from the fir
, flow tests show that the arteria1 sys
l tenn is of ample strength to delive
adequate quantities to the congeste
value and most of the high-value dis
tricts, but local Strengthening is re
| quired in some localities.
Distribution System.
. The arterial feeders are of amp,
capacity and well arranged for cor
centration of supply in the conges
ed value district, and supply a wei
arranged system of secondary feec
a ers covering, except in a few IL
q stances, all closely built sections. Mil
: or distributors are in general we
: gridironed and supported. Althoue
n considerable progress has been MAD
in the replacement of small main
there are several important section
= where the gridiron is of and 6-ino
& mSins, and in some extremely lor
" blocks mains are of these small
sizes; a number of dead ends ext
which could be readily eliminated.
s. Pipe.
n The cast-iron pipe is of amp
strength, properly tested before lai
carefully installed and in good sta
l. of preservation; carrying capacity
t high, as all not recently laid, exec
some of the smaller sizes, have be,
cleaned; some do not have suffice
ig protecting cover.
y. Gate Valves
e. Spacing is fair to poor and is wi
in many instances along the larg
mains and at intersections Care al
condition good.
Hydrants.
= Although many small hydrar
have been replaced and conditio
or materially improved in the more il
or portant districts, Is per cent. of tho
To in service are of inferior size. Dist
la button is good in the high-valve Sc
lie tons. but extremely poor in so,
,i closely built districts and outlyi
, residential sections. Hydrants {
