The Effects Of Grease On Septic Systems

Posted on: 21 August 2019


Some of the worst things that can go down your drains are fats, grease, and oil. Septic systems for residential areas are only meant to be used for the typical household and sewage products. Fats, oils, and grease are very harmful substances, and the amount of grease build-up must be kept under control. They can cause clogged pipes, septic tanks, or sewer lines. But if you regularly take steps to reduce the amount of grease, you can prevent many kinds of problems from happening in your septic system.

How Grease Builds Up

There are three levels in the household septic system. The bottom layer is also known as the "sludge layer" and consists of sewage waste that has not deteriorated yet. The middle comprises a mixture of fluids that have come from the bottom layer. The very top is called the "scum layer". Oils, fat, and grease build up there in the residential septic system. In fact, anything lighter than water goes to the scum layer. When the layer becomes too thick, wastewater can't flow from the septic tank to the last stage in processing. The bacteria will not be able to keep up with the grease build up and will slow down decomposition. 

Removal of Grease

When fats, grease, and oil have built up in your septic system, you should have it removed immediately. If you do not do so, then the grease can reach the leach field and then you'll have to have your pipes dug out and get new ones. Regular pumping and proper disposal can help prevent this problem. Don't use any chemical products that say that they can dissolve grease in your septic system. These products can destroy the good bacteria that dwell within the system and break down all the sewage and other solid waste. The best way to keep your septic system clear is to not put grease there in the first place. Place all cooking fats and grease into containers for reuse or disposal. Also, hiring a professional for routine septic tank maintenance can keep your pipes from getting clogged up with grease. 

Fats, grease, and oil are among the worst items that can go down your drains. Residential septic systems are intended to be used only for standard domestic and sewage products. If your septic system has fats, grease, and oil, you will want it removed immediately. This issue can be prevented by regular pumping and proper removal. A maintenance routine from a qualified septic inspection service can keep your system running smoothly.
