As strong and self-sufficient as it may be, a septic system still requires special care to remain in excellent condition. Every item you send down your kitchen drain ends up in your system, including ones shredded by your garbage disposal. Use the following guide to learn how to take care of your septic tank if you have this plumbing fixture.

How Garbage Disposals Can Harm Septic Systems

When you clean your pans and plates by dumping food scraps into the garbage disposal, all that waste flows out to your septic tank. Inside the tank is “good” bacteria, which break down and separate waste, filtering it until it can be deposited back into the soil.

However, the bacteria isn’t capable of breaking everything down. It has trouble making certain food items, such as cherry and peach pits or chicken bones, decompose. Even small ingredients, such as coffee grounds, can create a thick paste that coats the inside of the tank. All of these stubborn solids will remain in the unit for weeks or even months, and can only be removed through pumping.

Eventually, these can clog up the tank lines, preventing more waste from coming in or leaving to the drain field. Since the bacteria will focus on trying to break down those solids, there may not be enough organisms to break down the other waste, slowing the decomposition process. This could cause your tank to fill up prematurely, increasing the risk of backflow.

How to Prevent Issues

If you have a garbage disposal and a septic system, plan on throwing most food scraps into the trash or a composting bin. You should never put hard items, including coffee grounds, grains (like pasta and rice), and oils or grease down the drain. Additionally, avoid letting nonbiodegradable food packaging get in the disposal.

It’s also important to run the water while using the disposal to help scraps travel through the pipes. Use more water and mild soap when you’re done to clean the area and prevent odors.
