How Grease and Fat Affect the Septic System

How Grease and Fat Affect the Septic System

When it comes to household wastewater management, most of us are familiar with the basics. We’ve all heard the age old plumbing tale about putting grease and fats down our drains. If you don’t know, it’s a big NO for various reasons related to clogging your pipes, but what you may not know is those reasons extend even further, down into your septic tank

Grease and fat are common byproducts of cooking. Whether it’s the residual oils from frying bacon, the melted butter from sautéing vegetables, or the grease from roasted meats, these substances frequently find their way into our kitchen sinks. When grease and fats are hot and in liquid form, they may seem harmless. But as they cool, they solidify and adhere to the walls of your plumbing, and eventually, they can enter your septic system. This poses potential challenges for your septic system’s optimal functionality. Here, we’ll talk about how grease and fat affect the septic system.

The Impact on the Septic System

Clogging and Blockages

As grease and fat accumulate in your plumbing, they can congeal and cause blockages. This buildup restricts the flow of wastewater and can lead to backups, which are not only inconvenient but can also be costly to repair.

Reduced Bacterial Activity

A healthy septic system relies on beneficial bacteria to break down organic matter in the tank. Grease and fat are not easily digestible by these bacteria, leading to a reduction in their activity. This can result in slower decomposition of waste and, in the long run, a less efficient septic system.

System Overload

Over time, the accumulated grease and fat can fill a significant portion of your septic tank. This leaves less space for wastewater and solids, increasing the frequency of tank pumping and potentially overloading your system.

Leach Field Issues

When grease and fat clog your septic tank or plumbing, they can also make their way into the leach field. This can clog the soil, reducing its ability to absorb and filter wastewater properly. An overloaded leach field can result in the contamination of groundwater and potential damage to the environment.

How To Prevent Grease and Fat Buildup

Preventing grease and fat buildup in your septic system is both cost-effective and environmentally responsible. Here are some tips to help you keep your system functioning smoothly:

Collect Grease in a Container

Instead of pouring hot grease and fats down the drain, allow them to cool and solidify in a container. Once they harden, you can dispose of them in the trash.

Scrape Dishes and Pans

Before washing dishes or cookware, scrape off as much grease and fat as possible into the trash. This reduces the amount that enters your plumbing.

Use Strainers

Install sink strainers to catch food scraps and small particles, preventing them from going down the drain and contributing to clogs.

Regular Maintenance

Schedule regular septic system maintenance and assessments to identify and address any issues, including grease buildup, before they become serious problems.

Educate Household Members

Make sure everyone in your household is aware of the importance of disposing of grease and fats properly to prevent septic system issues.

Grease and fat may seem innocent when they go down the drain, but they can lead to significant problems in your septic system. By following some simple preventative measures and being mindful of what you put down the drain, you can help maintain a healthy and efficient septic system. This not only saves you money on repairs and maintenance but also contributes to the overall health of your environment.
