2. WATER AS A RENEWABLE RESOURCE
• Water can be considered a renewable material when carefully
controlled usage, treatment, and release are followed. If not, it
would become a non-renewable resource at that location. For
example, groundwater is usually removed from an aquifer at a
rate much greater than its very slow natural recharge, and so
groundwater is considered non-renewable.

3. WHAT IS A RENEWABLE RESOURCE
•
•
•
A renewable resource is a natural resource which can replenish with
the passage of time, either through biological reproduction or other
naturally recurring processes.
Renewable resources are a part of Earth's natural environment.
Renewable resources may be the source of renewable water.
However, if the rate at which the renewable resource is consumed
exceeds its renewal rate, renewal and sustainability will not be
ensured.

4. •
Removal of water from the pore spaces may cause permanent
compaction (subsidence) that cannot be renewed. 97% of the water on
the Earth is salt water, and 3% is fresh water; slightly over two thirds of
this is frozen in glaciers and polar ice caps. The remaining unfrozen
freshwater is found mainly as groundwater, with only a small fraction
(0,008%) present above ground or in the air

5. WHY IS WATER A RENEWABLE RESOURCE
• Water is a renewable resource because it evaporates out of the
oceans to clouds, which generate rain falling on the land. The
water then runs into rivers and dams where it is used and the
waste is partially cleaned before it makes its route to the sea,
where the cycle begins again.

6. WATER
• There is a fixed amount of water on the planet. It evaporates
out of the oceans into clouds which produce rain falling on the
land. The water then runs into RIVERS AND DAMS WHERE IT IS
USED FOR AGRICULTURE, INDUSTRIAL AND DOMESTIC USE.

•
THE WASTE IS CLEANED, OR PARTIALLY CLEANED AND MAKES IT
WAY TO THE SEA, WHERE THE CYCLE BEGINS AGAIN. IF THE
RAIN KEEPS ON FALLING IN THE CATCHMENT AREAS THEN we
won't run out.

7. BASIC FACTS ABOUT WATER AND SAYING
OF WWF.
• The vast majority of water on the Earth's surface, over 96 percent,
is saline water in the oceans. The freshwater resources, such as water falling
from the skies and moving into streams, rivers, lakes, and groundwater,
provide people with the water they need every day to live. Water sitting on
the surface of the Earth is easy to visualize, and your view of the water cycle
might be that rainfall fills up the rivers and lakes. But, the unseen water
below our feet is critically important to life, also. How would you account for
the flow in rivers after weeks without rain? In fact, how would you account
for the water flowing down this driveway on a day when it didn't rain? The
answer is that there is more to our water supply than just surface water,
there is also plenty of water beneath our feet.
