Water
Use Efficiency and Reuse
Water is the essential element.
Without
sufficient water, farming is not possible.
Crops must have moisture available to grow
and produce the food we need. At the same
time, plants and animals in natural
ecosystems downstream also need water to
survive and reproduce. We have designed
three major strategies to ensure our farm
and the ecosystems downstream effectively
share the water resources available.
Use sustainable
sources of water
In the past, the
only water resources we had were the rain
that fell on our property and the water
flowing in the channels surrounding our
farm. We had no way to know if we would
have enough water in any particular
season. The only thing we could do was to
store as much water as possible in the
farm dam we built. This meant that in
occasions less water was available for
environmental use downstream.
Now,
we have connected our irrigation system to
the local recycled water system which
provides a continuous supply of class
‘A’ irrigation water. Class ‘A’
irrigation water has been treated to very
high standards which ensures hygienic crop
production. From an environmental point of
view, class ‘A’ water means that more
rain water can flow to ecosystems
downstream.
Reduction of
water use
Regardless
of the source, water is a precious
resource that must be used as efficiently
as possible. To do this we must give our
crops exactly the amount of water they
need, no more, no less.
Over
the years we have developed a good
understanding of how much water each crop
needs. We deliver the correct amount of
water using our highly efficient computer
conhly efficient computer
controlled irrigation system. The
irrigation system is maintained in optimal
conditions to ensure its effective
operation every time it is needed. We
especially schedule irrigation for night
time to reduce water loss due to
evaporation.
Reuse
Even
with our efficient irrigation system, some
water is not taken up by the crops. Also,
there is some water that runs out of the
packing shed after washing our vegetables.
All this water is collected and channelled
back to be pumped into our main storage
dam. Our extensive drainage system, and
the silt traps and sump dams allow us to
recover and reuse nearly half of all the
water that comes out of our dams.
