Water-Cooler Cleaning
BNL Drinking-Water Quality Committee conducts the popular drinking-water
taste-test every year in the month of October during the two-day
Healthfest health, safety and fitness fair. During this time the
staff of the Water Treatment Facility (WTF) collects samples of
the “brands” of the water to be tasted and borrows
water coolers from around site to dispense the different brands.
Each and every one of these coolers are thoroughly cleaned up
before being used for the taste-test. This clean up is required
because of the build-up of dirt and mold. This mold and dirt definitely
has to be cleaned up to make the water hygienic. It has been observed
that some of the on-loan coolers are less hygienic than others.
There has been an incidence of a water cooler
that was borrowed in 2001, which was in a very bad shape and was
grossly contaminated. And the company that owned this cooler was
intimated.
Following that revelation, a Lesson Learned Communication was
developed. As part of learning a water-cooler cleaning procedure
was developed and a fact sheet on the importance of keeping water
coolers contamination-free was prepared and distributed
to all the users of water coolers. All this cleaning procedures
that have been adopted by cooler maintenance companies have indicated
that water coolers have evolved from simply relying on a block
of ice for cooling to meeting strict health, sanitation and environmental
standards
Water is the basic necessity of every living being which is consumed
by them almost every day. It is possible to go many days without
food, but we cannot go long without water. For years together
a primary means for providing the public with the drinking water
they need has been the drinking fountain and the water
cooler.
The drinking fountain was first developed in the early 1900s by
the companies Halsey Taylor and Haws. These two companies, founded
by Halsey Willard Taylor and Luther Haws respectively, pioneered
a major change in how water was dispensed in public places. By
initiating to put water fountain in public places, they also helped
reduce the instance of waterborne diseases among the general population.
In fact, Halsey W. Taylor's dedication to providing a safe and
hygienic drinking water to the public was prompted by his father's
death from typhoid fever caused by consuming contaminated water
supply.
For years the main source of drinking water in public places
like public buildings, schools and factories, was water fountains.
However, the desire for colder drinking water, especially during
hot summer months, brought about the introduction of chilled drinking
fountains. These initial models of the water cooler featured cooling
that was generated by a 20-pound block of ice.
The first few refrigerated water coolers were very cumbersome
floor standing units that used belt driven ammonia compressors
to chill the water. These water coolers were
so heavy that they had to be moved by several men or with a forklift!
A surprise news for you is that some of these units are still
in operation today!
In the early 1950s it was the top priority of the industry to
provide cold, refreshing drink of water to the school going students.
This led to the design and development of wall-mounted water coolers
which are more suitable to school environments.
Over the years, Halsey Taylor many variations of the wall-mounted
water cooler units were developed, including space-saving recessed
models that allow for uninterrupted corridors and hallways, making
them ideal for schools, hospitals and other buildings with high-traffic.
After the space saving effort towards the development of water
coolers and cold water fountains, the next major step in the water
cooler evolution process occurred in the 1960s with the evolution
of a cooler variation for physically challenged individuals. It
was the 1960s when the awareness came about that it might be difficult
for the people sitting in wheel chairs to access the water coolers
or fountains. That is when the industry began to recognize there
were physically challenged people confined to wheelchairs who
had difficulty drinking from the fountains and coolers put up
in the public places. And hence came the variation of the water
cooler which would be easily accessible even from the wheelchair.
Then in the 1980s came the government regulations that specifically
defined the needs of the handicapped. Keeping these regulations
in mind the industry responded by developing the Barrier-Free
water cooler which soon became the number one seller in the industry.
During this time there was a big wave to eliminate lead-bearing
components from potable water supply systems. The first change
was in solders and then other components soon followed, spurred
on by the Safe Drinking
Water Act. Then came the need to eliminate or control the
CFC refrigerants from the coolers. And the industry quickly responded
by moving on to HFC-134a refrigerant to replace the CFCs. The
1980s also saw an increased focus on the design and appearance
of water coolers and drinking fountains. As fountains and coolers
became more accessible and more practical than ever before, they
also became more attractive. In came the oval shapes, rounded
corners and contemporary finishes that blended in with a building's
decor became fashionable and remain so till today. In addition
to looking for quality and performance when specifying and selecting
a water cooler, architects, building owners and
facilities managers were also seeking units that looked good.
With the 1990s came Americans with Disabilities Act (ADA), which
more comprehensively defined the rights and needs of the handicapped
for access to many types of facilities. Because of this act came
about some additional dimensional and design changes to water
coolers and drinking fountains. This happened because
the water coolers and fountains were to become more accessible
to the physically challenged people. This act also recognized
the needs of able bodied people and those with bending difficulties.
ADA declared that public facilities needed to provide both wheelchair
accessible and standard height units. This resulted in the birth
of the increasingly popular bi-level unit.
What is the future of the drinking fountain and water cooler
industry? Where is it headed next? There will always be a concern
about the quality of water dispensed by these water coolers and
fountains, about the purity and safety of the water. This concern
of the public has prompted some manufacturers, including Halsey
Taylor, to secure full ANSI/NSF 61 certification for all their
water coolers and drinking fountains. ANSI/NSF
61, Section 9 is a standard that measures the contribution of
lead and many other harmful contaminants to the drinking water
by the water cooler and the fountain components. Two testing bodies,
Underwriter's Laboratories, Inc. and NSF International, have been
accredited by the American National Standards Institute (ANSI)
to certify NSF Standard 61, Section 9 compliance.
The Safe Drinking Water Act and State Legislation makes professional
plumbing contractors, engineers, architects and building owners,
as well as maintenance and facilities managers, responsible for
the quality of water dispensed from the products they specify
or install or even maintain. Because of this, offering water coolers
and drinking fountains that meet all the requirements of ANSI/NSF
61 has become very important. And each of the water coolers and
or fountains in any of the public places needs to meet these standards
and supply pure and clean and hygienic drinking water to people.
In addition to achieving this classification for lead, Halsey
Taylor is one of the manufacturers providing water coolers and
drinking fountains that meet the stringent requirements of this
standard for organic contaminants, regulated metals (including
antimony, arsenic, barium, cadmium, chromium, copper, lead, mercury,
nickel, selenium, silver, thallium, tin and zinc), radio-nuclides,
RVCM (residual vinyl chloride monomer) and solvent levels. It
is also a known fact that the majority of states are now looking
to the full ANSI/NSF 61 certification. It is very important for
all the manufacturers and service providers in the water
cooler and fountain industry to rise to the opportunity
and be able to offer products that meet this distinct classification.
While time and innovation can often lead to obsolescence, those
in this industry can take comfort in the fact that there will
always be a need for clean drinking water and hence, the need
for public water supply equipment in the shape of water coolers
and fountains. Consequently, the prime objective for the water
cooler industry is, to always work to provide the best products
possible for dispensing clean and hygienic drinking water to the
public.
