There are a lot of options for you out there when it comes to homemade septic tank treatment. You can purchase special septic tank system treatment agents to maintain your septic tank, but many people find them expensive, inconvenient, and potentially aggressive.

But don’t worry. We have some homemade septic tank treatment that you can use at home very easily.

Homemade Septic Tank Treatment

Tips: Be sure to avoid adding raw or cooked meat to the septic tank system through toilets, garbage disposal, or any other method. Meat is by no means a beneficial bacterium.

Self-made septic tank system treatment method

You can actually make an arrangement yourself to treat your septic tank system. It will be more environmentally friendly and provide more value when it comes to homemade treatment for a septic tank. Most of these treatments revolve around active yeast. When used alone or mixed with sugar or cornmeal, yeast serves as a way to balance bacterial levels in the septic tank system.

Notes: Always avoid adding any kind of oil, fat, or grease in any form to the tank.

Most Popular Method

In this method, you need to mix three cups of warm water, two cups of sugar, two cups of cornmeal, and two packets of yeast in a large bucket. Then, when the mixture starts to bubble, pour it into the toilet and flush it twice. It only needs to be placed in a toilet because it deals with the entire water tank, not the drainage system.

Tips: Avoid prolonged showering, washing clothes, or over-flushing the toilet within 8 hours after flushing. Don’t add too much water to the septic tank, as this may dilute the treatment agent and reduce its effectiveness.

Alternative Method

As we have mentioned earlier, yeast and sugar are very effective in naturally cleaning septic tanks. Here is a simple way to use them. You need two cups of brown sugar with five cups of warm water and three tablespoons of brewer’s yeast. Do not use bleach. Then dissolve sugar and dry yeast in water.

Tips: Pour the mixture into the toilet and flush away. This is best done at night so that the yeast can work overnight without flushing for at least 3 hours.

How to Treat a Septic Tank with Baking Soda?

This method is not only quick but also very effective. In this way, you need to use baking soda, vinegar, and lemon. First, mix one fourth cup of baking soda with half a cup of vinegar and pour directly into the toilet. Then, add two tablespoons of lemon juice. Combining baking soda and vinegar will cause a chemical reaction to heat it up and help break down dirt. The acidity of the lemon helps this process and also provides a pleasant fragrance. This solution will clean the toilet, and after flushing, it will do the same to the pipes in the system. And since it is a natural solution, it will not harm the healthy bacteria in your system.

How to Increase Bacteria in a Septic Tank Naturally?

Just like your stomach, septic tanks need good bacteria and enzymes to break down the solid matter that passes through them. These natural enzymes are proteins called pectinase or pectinase. If you don’t know, pectinase is actually a group of enzymes composed of lipase, hydrolase, and lyase, which can naturally decompose pectin and plant cell walls, helping to decompose and recycle plant waste. These beneficial bacteria and enzymes can come from various sources, but our favorite and most effective is actually the yeast.  Using yeast is an excellent way to maintain healthy bacterial levels in septic tanks. It is recommended that you flush 1/2 cup of active yeast into the toilet and then add another 1/4 cup every four months.


When you have no idea about exactly what you are doing, the septic tank system may be challenging to maintain. Avoid flushing things other than garbage and toilet paper into the tank. That means, use a trash can to leave any kind of feminine products. Baby diapers, wet tissues, and paper towels can only be placed in the trash can. Because these personal wipes claim to be safe for septic tanks, but they take a long time to decompose.

If you feel that your toilet is not flushing properly or your pipes can be cleaned, introducing harsh chemicals into your septic tank system will destroy the natural bacterial flora that helps your system function properly. So, you can use homemade septic tank treatment to increase natural cleanliness without affecting the functionality of the septic tank system.
