WHAT IS WATER
NEED OF WATER
• “A colourless, transparent, odourless,
liquid which forms the seas, lakes,
rivers, and rain, and is the basis of the
fluids of living organisms.”
Characteristics of Water
Water is a transparent fluid.
It forms the world's streams, lakes, oceans
and rain, and is the major constituent of the fluids of living
A water molecule contains one oxygen and two
hydrogen atoms that are connected by covalent bonds.
It often co-exists on Earth with its solid state, ice; and
gaseous state, steam (water vapour).
It covers 71% of the Earth's surface.
96.5% : in seas and oceans
1.7% :in groundwater
1.7% :in glaciers and the ice caps of Antarctica and
0.001% :in the air as vapour clouds.
A small fraction in other large water bodies.
• Only 2.5% of the Earth's water is fresh water and 98.8%
of that water is in ice and groundwater.
• Less than 0.3% of all freshwater is in rivers, lakes, and
the atmosphere, and an even smaller amount of the
Earth's freshwater (0.003%) is contained within
biological bodies and manufactured products.
• Pure H2O is tasteless and odourless.
• contains about 3.5% salt on average, plus smaller
amounts of other substances.
• There are some problems which causes the water
pollution . Like,
Discharge of waste materials or chemicals by industries.
It is estimated that around 2,00,000 people ritually bath
daily in river Ganga.
Water conservation encompasses the policies, strategies
and activities to manage fresh water as a sustainable
resource, to protect the water environment, and to meet
current and future human demand. Population, household
size and growth all affect how much water is used. Factors
such as climate change will increase pressures on natural
water resources especially in manufacturing and
Central Ground Water Board (CGWB), a subordinate office of
the Ministry of Water Resources, Go I, is the National Apex
Agency entrusted with the responsibilities of providing
scientific inputs for management, exploration, monitoring,
assessment, augmentation and regulation of ground water
resources of the country.
It was established in 1970 by renaming the Exploratory Tube
wells Organization under the Ministry of Agriculture, Go I. It
was merged with the Ground Water Wing of the Geological
Survey of India during 1972.
• There is a great need to
protect life, and water is
the life. A person can live
without food for about a
week but not a day without
• It has an essential role to
play for all living beings
involving human, animals,
birds and plants.
The goals of water conservation efforts include as follows:
• To ensure availability for future generations.
• ENERGY CONSERVATION: Water pumping, delivery and
waste water treatment facilities consume a significant
amount of energy. In some regions of the world over 15%
of total electricity consumption is devoted to water
• HABITAT CONSERVATION: Minimizing human water use
helps to preserve fresh water habitats for local wildlife
and migrating waterfowl, as well as reducing the need to
build new dams and other water diversion infrastructures.
• In implementing water conservation principles there are
a number of key activities that may be beneficial.
1.Any beneficial reduction in water loss, use and waste of
2.Avoiding any damage to water quality.
3.Improving water management practices that reduce or
enhance the beneficial use of water.
METHODS FOR PROTECTING
• Use bucket for bathing.
• If you see any water pipe leakage then immediately call
• Close the tap when it is not used.
• Adopt RAIN WATER HARVESTING methodology.
• Use alarms which give you alerts when your water tank
• This is the matter on which the discussion must be
started not to conclude. We have to join hands to save
water and save life.
