Water Storage Tanks
Harvesting Rainwater to Alleviate El Niño Effects
storage tanks are so important on a farm for harvesting rainwater.
Runoff from the roof
provides a free resource of good water that should never be wasted,
particularly in areas prone to drought.
Drought to an Australian farmer,
or any farmer for that matter, is a harrowing experience. Dams dry
up, snakes are on the move, bush fires become a reality and the death
of livestock and crops the inevitable outcome if water-saving
measures, like having farm dams or rain water storage tanks are not
It is a
reality that water is becoming a scarce resource,
and on average, every 3 to 7 years there is a weather pattern
rainfalls followed by drought. It is important, therefore to invest
in rain water harvesting during the good times.
it is not just Australia that suffers periods of drought, many
countries today have been experiencing climate change, manifested
through weather-related natural calamities in various stringency and
form seen in natural weather disasters of one form, or another. One
of these is an extended drought, called El Niño.
El Niño is the drastic change in local temperature and rainfall
patterns in isolated regions around the Pacific and elsewhere. It is
the kind of weather that no farmer wants to deal with, but it
happens, and it cannot be ignored.
This weather abnormality, whilst only occurs at irregular interval,
devastating effects to farmers and non-farmers, evidently linked to
environmental, health and business challenges.
Even if you own a suburban block and grow vegetables in your backyard,
you don't have a water storage tank, or a supply of underground
water, you too will be on water restrictions, and you will watch your
hard work shriveling up before your eyes. It is heartbreaking, but
can be avoided with some thought and planning.
According to the latest
scientific studies, there is at least a 70% possibility
that El Niño will fall at the end this year, predicting 2015 to set
a record as one of the warmest year in history. A
Yet, fear that demand in water will outstrip supply has already
in some countries as El Niño starts communicating early signs.
to the effects of El Niño can lead to:
migration of birds and other animals beneficial to the growth and
survival of other species that heavily relies on wetland vegetation
yielding of crops pushes economic
loss for farm owners
the water supply in
irrigation systems during drought can produce severe crop failure

and other herds, including wheat crops are threatened, while others
supply of water
increases during the dry season as usage restriction is implemented.
Large forest fires
temperatures in forests
can cause forest/bush fires. In other countries, in the southern
hemisphere fire prevention month which falls on the 3rd
month of the year is strongly utilised to carry out public awareness.
Increase in electricity bill
increase during the dry season as generation costs becomes higher due
to tight power supply.
and other household water consumption restriction
restrictions in some regions to specific residential/household
activities is mandated during El Niño, to give way to other
important usage and reduce risk of water supply shortage.
risk to certain seasonal diseases
protozoa, and bacteria can
pollute both groundwater
and surface water when
rainfall decreases. People who depend on private wells for drinking
water are at higher risk for drought-related infectious disease.
Shortage is a Global Issue
episodes of drought, water plays a vital role in sustaining societal
and biological diversity. However, despite the fact that the earth is
mostly composing of water, a significant percentage of it is seawater
and cannot be readily used when the main supply becomes insufficient.
Seawater desalination may help, but the process of separating salt
from water is costly.
irrigation (International Commission on Irrigation and Drainage) uses
a total of 2.7 million gigalitres to produce about 40% of the world’s
food crops. Yet, as the volume of water in dams, river basin, and other
continuously goes down below statistical average during drought, the
conditions surrounding it gradually worsen. Its substantial negative
impact on the overall population progressively intensifies,
especially to agricultural businesses.
are always worrying that they will one day not have the water needed
to continue their livelihood of being able to grow crops and raise
livestock in the way that they, and those before them, have done for
thousands of years. Water is indeed becoming in short supply and no
longer a resource that is available all year round, every year.
Storage Tanks Help with the Insufficiency of Water
presence of El Niño decreases the amount of rain that falls. In that
regard, cloud seeding, a form of weather modification to induce
rainfall takes place to encourage rainfall. Whilst this process is
essential, there could be other methods out there that are better and
more cost effective.

budget for 2014-2015 which aimed to maximize the benefits to both the
environment and the community.
fact that this unpredictable weather abnormality produced extreme
warming, the public should recognize the benefits of
rainwater tanks during this season.
using the rainwater previously stored in water storage tanks has
existed in the past, to others it is still in its infancy. Whilst
solid awareness becomes the subject for deliberation in some Asian
governments, others have already tarted implementing
its legislation to try and drought-proof residential and farming

and water storage tanks
account for just 15% of agricultural water (1,315GL).
to Use your Water Storage Tanks
using even the biggest

water needs, it will be able to water your vegetables, wash your car,
top up the swimming pool, provide water for your livestock, use it
for washing your dishes, connect to your washing machine, or even
Whatever water you save
will be a bonus. You could
also use this water for drinking purposes if you had to, but it has to
well filtered, and even boiled before using.
You will be surprised just
much water comes off your roof, and by connecting a water storage
tank to the house, and buying enough tanks to give you water through
the lean times, you will be a lot better off than most of your
friends and neighbors!

are able to double your storage capacity.
Please think about getting
some water storage tanks around your property for harvesting rainwater
that is so precious in times of drought and extreme weather conditions.
