Water is essential for all life on Earth. It covers 70% of the planet's surface and is made of hydrogen and oxygen molecules. The hydrological cycle moves water continuously through Earth's atmosphere, land, and oceans. While most water is undrinkable salt water, fresh water sources like rivers, lakes, groundwater, and glaciers provide water for agriculture, industry, households, and more. Water conservation aims to reduce usage and reuse water through practices that save both water and energy while lowering costs. Small behavioral changes in using appliances and outdoors can significantly reduce individual water consumption.

1. WATER

2. Introduction
• Water is one of the most important
substances on earth.
• All plants and animals must have
water to survive. If there was no
water there would be no life on
earth.

3. Composition Of Water
• Water is a chemical substance with
the chemical formula H2O.
• A water molecule contains one oxygen and
two hydrogen atoms connected by covalent
bonds.
• Water is a liquid at ambient conditions, but
it often co-exists on Earth with
its solid state, ice, and gaseous state
(water vapour or steam).
• Water also exists in a liquid crystal state
near hydrophilic surfaces.

5. • Water covers 70.9% of
the Earth's surface, and
is vital for all known
forms of life.
• Oceans hold 97% of
surface
water, glaciers and
polar ice caps 2.4%, and
other land surface water
such
as rivers, lakes and pond
s 0.6%.
• A very small amount of
the Earth's water is
contained within
biological bodies and
manufactured products.

10. Water Conservation
• Water conservation refers to reducing the
usage of water and recycling of waste water
for different purposes such as cleaning,
manufacturing and agricultural irrigation.

11. Why to Conserve Water?
• When you use water wisely, you help
the environment.
• When you use water wisely, you save
energy.
• When you use water wisely, you save
money.

12. How to Conserve Water
• Engineering practices: practices based
on modifications in plumbing, fixtures,
or water supply operating procedures.
• Behavioural practices: practices based
on changing water use habits.

13. Water Conserving Facts
• Around 75% of the water used inside the
home is consumed in the bathroom.
• Every toilet flush uses up to 5 gallons of
water.
• More than 30% of household water is
consumed in outdoors, such as watering
lawns.
• Treating water and delivering it into
households requires a lot of energy. A faucet
when run for 5 minutes takes as much energy
as running a 60-watt light bulb for 14 hours.
• We can save up to 8 gallons of water per
day, when we turn the tap off while brushing
our teeth. By doing so, we will be able to
save about 200 gallons of water every
