On earth, the place where we live in, water covers 70% of the total area and it comprises of inland seas, lakes, ponds, rivers along with water found below the surface(ground water).

The growth of population and industrialization has led to increase in usage of water in many cities of the world since it is used for farming, fulfilling essential needs for livestock and human beings and irrigation facilities.

In recent times, since distribution of water has become the monopoly of many country departments, people have to depend on the Government resulting in decrease of public contribution regarding management of water and total disregard of old systems of conservation of water resources. A survey has stated that the normal public seems to have the view that water resources are abundant, but does not seem to understand the facts and figures of quality water which can be used for domestic use.

Example, neither seawater, nor water found in marshes, salty lakes or swamps can be used for domestic use. Water with minimal treatment for use can be found in rivers, ponds, lakes, wells and from ground water table.

It is a fact that many countries will face water crisis in the future and it is time that the departments concerned reform their systems of water resources management. Recent scientific instruments and systems have to be used according to the climate conditions and appropriate procedures with improvements in law should be suggested and implemented as soon as possible for water conservation. For any new measure on behalf of Government, active people participation should be encouraged to make it a successful venture.

Rain water harvesting method has been used since olden days (3rd century BC) in Pakistan, Iran and India. The method practiced was the conversion of land areas into lakes, tanks, wells as storage areas for rain water. The public took responsibility for maintaining the water resources to be used for domestic and irrigation purposes.
