With only 1% of water available for human
consumption, doesn’t it make sense that we
should treat our water supply with more
^ High specific heat- cools down and heat up slowly. It also has high
latent heat of evaporation – takes high energy for vaporisation
^ Excellent solvent – carrier of nutrients. (O2 and Pathogenic Micro-
^ Anomalous expansion behaviour – expands when cooling.
8% USE OF WATER
• 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.Climatic Changes, Population, household size
and growth and affluence all affect how much water is used.
The goals of water conservation efforts include as follows:
• To ensure availability for future generations, the withdrawal of
fresh water from an ecosystem should not exceed its natural
• 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 management.
• 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.
• Today the earth is in the need of water conservation as the
quantity of water is going down day by day
• Though we say that the Earth is a Blue Planet ,the reality is
that only 3% of the total water available is fit for drinking.
• Out of that 3% also , 2.997% is locked up in polar ice caps,
and only 0.003 % is there in form of surface & ground water
• The rate is still declining and the reason is......
• WATER POLLUTION
• Water pollution is a major global problem which requires
ongoing evaluation and revision of water resource policy at all
levels (international down to individual aquifers and wells). It
has been suggested that it is the leading worldwide cause of
deaths and diseases, and that it accounts for the deaths of
more than 14,000 people daily.
1) When annual rain fall is below normal and less than evaporation,
drought conditions are created.
2) Unlike flood, it is not a distinct event.
3) It is often caused by the complex factor.
Drought is an extended period when a region notes a deficiency
in its water supply whether surface or underground water. A
drought can last for months or years, or may be declared after
as few as 15 days
• It is the extreme deterioration of land in arid and
dry sub-humid areas due to loss of vegetation and
• It results chiefly from man-made activities and
influenced by climatic variations.
Consequence of desertification:
1. Economic loss
2. Worsening drought
3. Lowering living standards
4. Environmental refuges
Water conflict is a term describing a conflict between
countries, states, or groups over an access to water
1. Local Level:
Example: Between villages or streets or houses
2. National level:
Example: Cauvery river – between Karnataka and Tamil Nadu
3. International level:
Example: Jordan river water conflict between Sudan, Egypt

Rain Water Harvesting is capturing and storing rainfall to
irrigate plants or to supply people and animals.
A well-designed system will also decrease your landscape
All you need for a water harvesting system is rain, and a place
to put it.
A "catchment" is any large surface that can capture and/or
carry water to where it can be used immediately or stored.
Wash laundry and dishes with sufficient
amount of water only
Always turn off running water
Take shorter showers
Eliminate any and all leaks
Reduce the flow of toilets and showerheads
I don’t think anyone can say that water
conservation has disadvantages.
Factories produce harmful waste products which if
purified and discarded help in keeping the
surrounding of the factories safe and keep local
residents out of health problems.
Rivers and lakes will remain clean.
Hence can be used for irrigation and cultivation
Fishes and other aquatic life forms can breathe well
in the water.
Various treatment methods like trickling filter
method, activated sludge process and RBC help in
purifying sewage water.
Nitrogen and phosphorus in sewage remains in the
effluent from secondary treatment. These inorganic
nutrients can cause eutrophication.
pollution and health
Protects drinking water
Reduces the need for
costly water supply and
Concluding I would like to say that WATER is an
essential natural resource and a very important part
of human life and hence should be conserved.
This will help us and our future generation to live a
longer, better and a peaceful life on this planet.
