2. DID YOU KNOW?
THE GLOBAL BURDEN OF HUMAN DISEASE CAUSED BY
SEWAGE POLLUTION OF COASTAL WATERS HAS BEEN
ESTIMATED AT 4 MILLION LOST PERSON-YEARS ANNUALLY.
A VARIETY OF MATERIALS ENTERS INTO THE SEWAGE
SYSTEM FROM A TYPICAL HOME, OFFICE OR INDUSTRY.
SEWAGE CONTAINS SOLIDS AND CHEMICALS LIKE
NITROGEN, PHOSPHATES AND BACTERIA THAT AFFECT THE
ENVIRONMENT.

3. *Water covers over 70% of the Earth’s
surface and is a very important resource for
people and the environment.
* Water pollution affects drinking water,
rivers, lakes and oceans all over the world.
* This consequently harms human health
and the natural environment.

8. .
Microorganisms that live in water feed on
biodegradable substances. When too much
biodegradable material is added to water, the
number of microorganisms increase and use up the
available oxygen. This is called oxygen depletion

9. Groundwater Pollution

12. *Industrial and agricultural work involves the use of many
different chemicals that can run-off into water and pollute it.
*Metals and solvents from industrial work can pollute rivers
and lakes. These are poisonous to many forms of aquatic life
and may slow their development, make them infertile or even
result in death.

14. Sewage is the term used
for wastewater that often contains
faeces, urine and laundry waste. In
developed countries, sewage often
causes problems when people flush
chemical and pharmaceutical
substances down the toilet..

16. Dumping of litter in the sea can cause huge problems.
Different items take different lengths of time to degrade
in water:
*Cardboard – Takes 2 weeks to degrade.
*Newspaper – Takes 6 weeks to degrade.
*Photodegradable packaging – Takes 6 weeks
to degrade.
*Foam – Takes 50 years to degrade.
*Styrofoam – Takes 80 years to degrade.
*Aluminium – Takes 200 years to degrade.
*Plastic packaging – Takes 400 years to degrade.
*Glass – It takes so long to degrade that we don’t know
the exact time

20. *Operations conducted by nuclear power stations
produce radioactive waste.
*Mining and refining of uranium and thorium are
also causes of marine nuclear waste.
*Waste is also produced in the nuclear fuel cycle
which is used in many industrial, medical and
scientific processes

27. COMMON BENEFITS OF SEWAGE WASTEWATER
TREATMENT
• SAVE MONEY BY
RECYCLING THE
WASTEWATER FOR USE
AROUND THE GARDEN
• LIMIT THE IMPACT YOUR
HOME HAS ON THE
ENVIRONMENT
• PROTECT PRECIOUS
STORES OF
GROUNDWATER AND
STORED RAINFALL IN
DAMS BY RECYCLING
• REDUCE YOUR IMPACT ON
MUNICIPAL SEWAGE
SYSTEMS BY INSTALLING A
DOMESTIC TREATMENT
SYSTEM

28. ENVIRONMENTAL BENEFITS
• LESS CONTAMINATED SEDIMENTS AND SLUDGE
BUILD-UP
• DECREASED PATHOGENS AND BOD (BIOLOGICAL
OXYGEN DEMAND)

29. ECONOMIC
BENEFITS
• INCREASED PROPERTY VALUES
• REDUCED HUMAN HEALTH
RISKS
• INCREASED RECREATIONAL
OPPORTUNITIES

30. WHY IS A SEWAGE TREATMENT PLANT
NECESSARY?
• A SEWAGE TREATMENT PLANT ACTIVELY TREATS
SEWAGE IN THE TANK BEFORE SAFELY DISCHARGING IT
INTO THE ENVIRONMENT.
• IT REMOVES 90-99% OF THE SOLIDS AND POLLUTANTS
TO COMPLY WITH LOCAL AND/OR NATIONAL
ENVIRONMENTAL REGULATIONS.
• IT POTENTIALLY IMPROVES THE RESALE VALUE OF YOUR
PROPERTY.

31. ADVANCED WASTEWATER TREATMENT SYSTEMS
INVESTMENTS IN SEWAGE TREATMENT PLANTS CAN
HAVE A VARIETY OF IMPLICATIONS AND BENEFICIAL
EFFECTS. FOR COST-EFFECTIVE WASTEWATER

33. What Can You Do?

35. Denitrification can be used to prevent the leaching of nitrates
in soil, this in turn stops any ground water from being
contaminated with nutrients.
♠Fertilisers contain nitrogen, and are applied to crops to help
plant growth .
♠ Bacteria in the soil convert the nitrogen in the fertilizer to
nitrates, making it easier for the plants to absorb.
♠ Immobilization is a process where the nitrates become part
of the soil organic matter.
♠ When oxygen levels are low, another form of bacteria then
turns the nitrates into gases such as nitrogen, nitrous oxide and
nitrogen dioxide. The conversion of these nitrates into gas is
called denitrification. This prevents nitrates from leaching into

36. Bringing
Awareness:
treating sewage
before dumping
Leakages from
Drainage Pipe
Lines
Industrial Wastes:
strict orders not to
dump waste
before treating
Don’t use too
much of
Pesticides
Avoid Paint and
Petroleum to sinks
Avoid Oil Spills in
oceans
PREVENTION OF WATER
POLLUTION
