Fresh water has always been a limited resources in some parts of the world. Today, however, growing worldwide demand has made this a global problem. What are the causes of the increased demand, and what measures can government and individuals take to respond to this problem.

Methods to manage

water

consumption, especially fresh and clean

water

have been among the hot topics in sustainable development research communities. So rapid has been the world's

population

growth rate that humankind is currently on the verge of losing all of its

water

resources.

Thus

, in search of finding a reliable solution for

such

an inter-generational problem, development experts have reached a consensus on rethinking freshwater usage in a more efficient way as the main axial solution.

To begin

with, the exceeding humankind

population

and

consequently

the growing of

water

-consuming industries led to drastic

demand

for fresh

water

on the one hand and even recycled

water

on another hand. In better wording, the human

population

presently is two and a half times as of 1960. Regarding

this

,point the drinking

water

gross

demand

and indirect

water

demand

of

water

-consuming industries, have grown in the same ways.

For instance

, Iran's

population

after the 1979 revolution doubled and

also

fifteen steam

water

power generation plants, in response to electricity

demand

, have been launched.

As a result

, so much has exceeded the

water

usage either clean or recycled, that two main rivers of Iran, Zayande Rood and Zabol Rood, have completely lost their

water

capacity.

Therefore

, to address

this

problem, the government should have a laser point focus on improving the efficiency of drinking

water

usage as the

first

step and

then

replacing the

water

-consuming industries with alternative ones. In the more simple words, in fact, the government not only should train and encourage households to avoid wasting drinkable

water

in their daily life but

also

should make tough obligations for new building construction project managers to equip buildings with modern eco-friendly

water

facilities that

for instance

provide families' member with

this

opportunity to take shower with clean but non-drinkable recycled

water

. To conclude, to manage

this

problem, as far as the humankind

population

is increasing, stakeholders should focus their concentration on a key strategy, make fresh

water

allocation more efficient.
