Know How Fats, Oil, and Grease Affect Drainage and Sewer Systems

05 March 2019

One of the most critical systems that keeps civilisations together are sewer systems. Without functioning sewer systems society would quickly deteriorate, which is why it is paramount to keep drainage and sewer systems free of fats, oil, and grease.

Fats, oil, and grease can serious hinder and even clog drainage and sewer systems. The best way to prevent this from happening is by educating the public about these materials, so people do not dispose of them down drains or sewer lines.

How Fats, Oil, and Grease Restrict and Clog Drainage and Sewer Systems

How do fats, oil, and grease cause drainage and sewer blockages? When these substances are flushed or poured down toilets, sinks, or drains, these will travel down the sewer system until cool enough to harden. When fats, oil, and grease harden, these will stick to the inner walls of pipes, and over time they will accumulate to the point of restricting and preventing the flow of liquids.

When this happens – sewer pipes become clogged with harden fats, oil, and grease – the hardness of the blockages make it extremely difficult to unclog, as most sewer pipes and drainage are located underground. Where do fats, oil, and grease come from? That is an important question to ask, as the answer will help to solve the problem of drainage and sewer system blockages.

The most common sources of harden fats, oils, and grease come from households that dispose of old sauces, salad dressings, fats, cooking oil, butter, margarine, lotions, liquid soaps, cosmetics, gravies, milk, yoghurt, cream, and other dairy products down drains and toilets. Sadly, while most people may reason that once they flush these items down the drain, they are gone for good, but that is not the case at all.

Fats, oils, and grease from all of these products “will” build up in pipes and eventually create blockages that lead to problems, such as:

– Raw sewage overflow.
– Basement flooding.
– Graywater backflow from drains.
– Potential exposure to disease-causing organisms.
– Expensive maintenance cost to repair damaged drainage and sewer systems.

To prevent drainage and sewer system blockages is easy to do, simply do not pour any fats, oil, grease, or anything that contains these down drains and toilets. Instead, dispose of these where they belong, in your Green Bin.
