Part1
What
is the problem? 
Well after the
World War-2 was over, a forecast was made that there would break out another
world war; and that time the cause would be water. It is surprising to know
that although the earth is composed of three types of water, there is an acute
dearth of sweet water primary for sustaining life on the planet. Water problems
springs up when there is an acute shortage of potable water. Things have
already taken such an ugly turn that the United Nations have declared water  problems  a global issue which every country is expected
to respond to. If one digs deep into the root causes of such a problem, some
unpalatable truth will be exhumed. It has, since time immemorial, kept on
eating in to the natural resources to ensure its prosperity. Acts like massive
deforestation are unplanned industrialization have led to the drying up of
water. Indiscriminate use of strong chemicals for a long period of time has
exposed ground level water to the threat of being contaminated beyond
consumption. Therefore, it is quite evident that not only water resources are
shrinking; it is slowly reaching a point where it would tip the scale of
consumption. Therefore, if quick action to check water wastage is not
undertaken, human civilization will be under serious threat.
Part2
What is the Description of
Problem ?
The example of water crisis in the UAE
can be cited in this regard. The inhabitants of the Emirates had taken it for
granted that since water was a resource available free of cost, it could be
used at one’s sweet will. Mindless consumption has now resulted in acute
scarcity in ground level storage of drinking water. Situation has come to such
a pass that the Government is concerned and is thinking of bringing about
necessary regulations related to use of water. Since it is located at the
desert, the UAE in bereft of the graces of rain water, rivers or underground
water. It largely depends on desalinized sea water. Therefore, it is quite
evident that resource is quite limited. Besides wastage in the households, the
extent of water going waste in the farmlands is too overwhelming to comprehend.  In this context, reference can be cited of
the Klang Valley Water crisis that occurred at Kuala Lampur in Malaysia. In the
year 1998, the water level of three large dams' viz.  The government was forced to introduce the
system of water rationing to cope with the evolved passé. In the UAE, rapid
industrialization has paved the way of an unplanned utilization of resources,
among which water is no exception. But, one needs to understand, desalinized
water can never be the be all and end all because a considerable amount of
energy goes in to the waste in the process of sanitizing saline water in to a
consumable variant.
What
is the solution ?
There are indeed some solutions to the problem.
At the very onset, the water supply network needs to be using methods like
single optimization and multiple objective optimizations. In the first method,
pipe flow rate and pipe flow velocity are controlled so as to check excess
water drainage. In the second method, minimizing cost at the time of treatment
of saline water is looked into. However, apart from these mechanical methods,
there are certain other cost effective methods as well which, when effectively
applied, yield amazing results. Afforestation is one such method to retain
ground water. Apart from maintaining bio-diversification, trees actively
participate in water conservation through their roots. Other sources of energy
should also be resorted to. Hydroelectric power very often poses a threat of
unnecessary wastage of water. In that case, solar and atomic energy should be
used as effective backups. In the UAE, an extensive campaign should be
initiated against rampant misuse of water. The government should come up with
the idea of installing water meters in households to keep tab on the
consumption of water. In other words, water should be a taxable entity. Pumping
wasted water into the ground after effective cleansing is another relevant
option.
