Only two of the hydrants have any value in fighting a fire with hoses

attached to the hydrant. A few houses within the immediate vicinity of the

hydrant could be protected by hose connection to the hydrants. The primary

use of the fire hydrants can only be to refill the fire department's tank trucks.

The district also provides refilling points at the two booster pump stations.

With the proper adapters and valves, these two locations will also refill tankers

quickly.

The recommended fire flow rates are discussed in the following section.

2. Insurance Services Office C~iteria - Uniform standards for fire protec-

tion requirements are provided by t~e Insurance Services office in a publication

entitled "Guide for the Determination of Required Fire Flow." Based on the

type of home construction, the aver8ge amount of floor space, and home spacing;

the recommended fire flow criteria for the Brook Forest area is as follows:

I

I

(a) Fire Flow - 500 gpm for two hours. Absolute minimums are 250 gpm

for two hours or 500 gpm for one hour.

I

(b) Storage capacity for fire fighting reserve of 60,000 gallons.

I

(c) Fire hydrants at a density of one per 3.7 acres of service area.

(d) Residual pressure at the fire hose nozzle of 20 psi.

I

The district as a whole is deficient in each of these four areas. The

4-inch mains cannot supply 500 gpm at the available pressures created by the

storage tanks. A flow of 250 gpm is feasible in some areas of the district

and depends on the distance from a tank and the elevation difference. Although

the total available storage exceeds 60,000 gallons, the stored water cannot

be transferred rapidly to all parts of the district.
