DEEP WEELS WITH A MODERN EFFICIENT WATER
PLANT PROVIDE THE VILLAGE WITH THE
FINEST WATER IN PALM BEACH COUNTY
The Water Plant is located west
of the Village of North Palm
Beach, on Richard Road.
It was originally constructed in
1956 with a capacity of 1.5 million
gallons per day, and expanded in
1962 to 6 million gallons per day.
Water is taken from 11 wells,
aerated, chlorinated, softened, sta-
bilized and filtered. All phases of
treatment are carried out in a Per-
mutit precipitator softening unit.
This softening unit is - divided into
primary and secondary mixing and
clarification zones.
Water from the wells is first
aerated and passes downward
through the primary mixing zone
of the precipitator; here the water
is softened with chemical hydrate
lime. After the application of lime
for softening, the water rises to the
secondary mix where the softening
reactions are completed and coagu-
lation of lime sludge is started,
using activated silicate as a coagu-
lant aid. Here also chlorinaation is
accomplished.
In the clarification zone the co-
agulated lime sludge drops to the
bottom of the unit, the treated
water passes by gravity to five
rapid sand filters.. On the way to
these filters calgon is added to
stabilize the softened water. The
water is then filtered and stored in
the million gallon ground storage
tank and clear well until needed in
the Village.
The lime slurry which falls to
the bottom of the unit is drawn off
every two hours or as required by
the percentage of the lime needed
to soften the water coming into the
plants.
The lime feeder has a capacity
of 1200 lbs. per hour, which feeds
to the unit in parts per million; an
average day's run of 3600 gallons
per minute would require between
4500 and 5000 lbs. of lime per day
for softening purposes.
The laboratory at the Water
Plant is equipped to run complete
chemical analyses and a qualified
chemist and operators are on duty
at all times.
Tests are run every two hours.
These tests consist of a pH, alka-
linity, iron content, total hardness,
chloride determination of raw
water, color and chlorine. The re-
sults of these tests are recorded
once a day and filed with the Board
of Health once a month.
The effluent from all treatment
units is checked by the operator
every two hours and recorded on
daily log sheets.
EMERGENCY POWER: In case
of power failure, the plant is
equipped with a 200 K.W. emer-
gency generator, driven by a gas
powered Waukesha engine. This is
capable of running the plant at
2/ 3 capacity.

HIGH -SERVICE PUMPS. There
are 4 High -Service pumps at the
plant which have different ratings.
2 1500 gal. per minute pumps
1 500 "
1 3500 "
These pumps are capable of de-
livering 6500 gallons per minute to
the entire system. Our elevated
storage tank has a capacity of 300,-
000 gallons which maintains a
static head of pressure in our en-
tire system of 54 lbs.
AREAS SERVICED. North Palm
Beach Utilities also serves the
town of Lake Park, some parts of
Palm Beach Gardens, including
Alamanda School, Hidden Key,
Hidden Key North, and Lost Tree
Village.
Our distribution system consists
of 72 miles of pipe from 4 -inch to
16 -inch. There are also 264 fire
hydrants in the system.
Our goal in the past ten years
has been to supply our customers
with the highest quality water
that can be produced, along with
the best service available, and this
will be our continuing goal in.
years to come.
