1.0 Introduction
Over two thirds of Earth's surface is covered by water; less than a third is taken up by land.
As Earth's population continues to grow, people are putting ever-increasing pressure on the
planet's water resources. In a sense, our oceans, rivers, and other inland waters are being
"squeezed" by human activities — not so they take up less room, but so their quality is reduced.
Poorer water quality means water pollution.
We know that pollution is a human problem because it is a relatively recent development in
the planet's history: before the 19th century Industrial Revolution, people lived more in harmony
with their immediate environment. As industrialization has spread around the globe, so the
problem of pollution has spread with it. When Earth's population was much smaller, no one
believed pollution would ever present a serious problem. It was once popularly believed that the
oceans were far too big to pollute. Today, with over 8 billion people on the planet, it has become
apparent that there are limits. Pollution is one of the signs that humans have exceeded those
limits.
How serious is the problem? According to the environmental campaign organization WWF:
"Pollution from toxic chemicals threatens life on this planet. Every ocean and every continent,
from the tropics to the once-pristine polar regions, is contaminated."

2.0 Problems Statement
The water pollution that involve river, lake, catchments area and many else becoming
more serious and this situation are not indicate the recover sign. This shows the third class
minded that some individual have for not sensitive and responsibility about the environment and
water pollution.
Domestic waste water disposal directly to the river is one of the factors that contribute the
pollution of water. It is because the water is not undergoing the treatment before release into
river. These situations are commonly happened in our country. There are still lacks of seriously
attention from all consumers such as residency, schools, shop or restaurants about this system
even though many kind of method for water treatment available nowadays.
The untreatment water can make a hideous effect to many things such as aquatic live
system. The pollution water can kill this live and the system of aquatic live will ruined. The
pollution water also can bring disease to human and this is really dangerous for our community
lives. Besides that, the pollution also brings the long term negative effect for the environment
and this is really anxious.

3.1 This oil is causing discomfort to the animals?
Imagine yourself as a killer whale. You are swimming around when you decide to stick your
head out of the water to take a breath. As you are taking a breath, you see a large stream of thick
black oil heading your way. You go back under water only to find other animals dying one by
one because the oil is damaging their bodies.This is the way some animals must die in the ocean.
They die because of an oil spill occurring in their habitat
What affects do oil spills have on animals?
Birds die from oil spills if their feathers are covered in oil. The bird will then be poisoned
because it will try to clean itself. Animals may die because they get hypothermia, causing their
body temperature to be really low. They may die from really low body temperature. Oil may also
cause the death of an animal by entering the animal’s lungs or liver. The animal will then be
poisoned by the oil. Oil also can kill an animal by blinding it. The animal will not be able to see
and be aware of their predators. If they are not aware of other animals, they may be eaten.
3.2 How to reduce waste oil from cafeteria?
By using Grease Trap
3.2.1 What is a grease trap?
Grease trap is a light weight, durable and portable fiber glass tank. It has the latest cutting edge
technology that meets municipal engineering requirements and specifications. It can be easily
installed in kitchens.
3.2.2 Why grease traps are needed?
• Prevent kitchen wastes, fats, oils and grease from clogging pipes and sewage
• Prevent environmental pollution of water ways
• Environment friendly discharge
• East maintenance and cost savings

3.4 How the system works the oil filter?
A grease trap works by capturing absolutely everything that goes through the drain,
including water, grease, and other solid and liquid matter. A grease trap has two separation
basins. The first basin fills with all the matter that is drained from the sink. There, the matter is
cooled. When grease is cooled, it congeals, becoming a solid. Both the solid matter and the
congealed grease float to the top, leaving the liquid at the bottom of the first basin. Towards the
bottom of the first basin is a tube that allows all liquid matter to flow into the second basin. The
second basin is used to trap any additional grease that may have gotten through the first basin, so
the same process is repeated. The grease trap needs to be cleaned in order to work properly, and
it is possible for the grease trap to become too full to function.
3.5 How to create an effective filter system
3.5.1 Objective
i. To minimize the quantity and proportion of oil and grease in the water body.
ii. To improve the quality of surface water runoff after the treatment before its flow river.

3.5.4 Where to install?
A grease trap is a device that is required by law in every restaurant, cafeteria, catering operationand any other commercial cooking facility. It prevents fats, oils, wax and other debris from
falling into the city's sanitary sewer system, which helps prevent blockage and overflows that
often occur if such things enter the system. A grease trap must be accessible so you can clean it
out, but you do not need to clean out a trap in your home as frequently as one in a restaurant.
1. Determine where to install the grease trap. The area must be large enough to fit the trap.
The best place for the grease trap is under the sink. The trap will be a large square box
that holds up to 40 liters and will need to be cleaned out at least once every 2 years.
2. Connect the grease trap. There are three connections. One is on the upper right side and is
connected to the holding tank vent. This will be the vent connection and control the flow
of the trap. Use a clean out tee before attaching to the vent.

3. Connect the left connection to the sink pipe. The pipe will come down from the sink and
loop up to another pipe that is straight. Connect the grease trap to the pipe that goes down
from the straight pipe.
4. Attach the bottom right opening of the grease trap to the sewer pipe. This will send the
liquid to the sewage system.
5. Run hot water after any greasy liquid or food goes down the drain. This will help the
grease trap work better and last longer between cleanings.

4.0 Conclusion
In conclusion, the grease trap that we produce is suitable for use by operators of food
because it can help to care of the environment by reducing water pollution in terms of discharge
of oil into a river. In addition, it can prevent kitchen wastes, fats, oils and grease from clogging
pipes and sewage, prevent environmental pollution of water way, environment friendly discharge
and east maintenance and cost savings We would like to suggest to the authorities to require all
food premises are equipped with fuel filters to keep the environment clean.
