installed as use dictates). Using the previously described criteria of

I

55 gallons per person per day, the systems capacity is t3323 persons.

Allowing for the existing users, this would allow for an additional 3,000

I

users or approximately 857 single tap equivalents. With the noted growth

rate of 7%, and disallowing for any great industrial and/or commercial users,

the system is more than adequate beyond the year 2000. Minor additions to

I

the treatment plant at that time or sooner could triple its capacity.

c. Storage:

I Total estimated consumption per day equals 50,~80 (150% of existing

use). Ascribing to the Fire Underwriter's Association code for fire protection:

I

Q = 1000 gpm (2.28 cfs)
Duration = 4 hours
Storage required = 240,000 gallons
Daily Use = 50,480

I

I

Total required storage capacity = 300,480

Therefore a 350,000 gallon steel or concrete treated water storage

I
I

tank can be used.

Should problems occur in the treatment plant or'on the transmission

line, this would leave the Town with a 7.51 day supply at normal usage rate and

I

a 5.08 day supply at 150% of normal usage.

(Note: Although design criteria used dictate fire protection by the Fire Under-
writer's Association, no rate decrease in fire insurance premiums can be assured.
Though dependent on adequate fire protection capacity, other parameters such as
adequate equipment, experience of firemen, nearness to communities with full
time fire department, etc., are taken into consideration.)
