Worst Toilet Paper For Septic Systems You Need To Avoid

When it comes to choosing toilet paper, people often focus on certain attributes: sturdy, supple, and pleasant when using it.

However, few realize that good paper towels also aim to degrade fast once flushed since the materials used and their thickness can impact the lifetime of your septic tank. So, which is the worst toilet paper for septic systems?

4 Worst Toilet Paper For Septic Systems

Flushable Wipes

Flushable wipes are by far the worst toilet paper to use with a septic system. Flushable wipes are not technically toilet paper, but most people treat them as such. Although flushable wipes are advertised to be flushable, they are extremely harmful to septic systems. 

Flushable wipes are tough to decompose, resulting in a lot of muck in the system. It will cause the bacteria in the sewer pipe to decompose more slowly. Simultaneously, flushable wipes block drain pipes quickly.

Dyed Toilet Paper

Dyed toilet paper is the next type we don’t suggest for septic tanks. In the 1960s and 1970s, manufacturers dyed toilet paper in different colors to make the bathroom more vibrant. Though those papers looked eye-catching, they contained many harmful compounds to the microorganisms in the septic system.

Fortunately, almost all toilet paper is white these days. If you find dyed toilet paper on sale, it’s best to go with the traditional white color to avoid harming the microorganisms in the septic system.

Thick Toilet Paper

Thick toilet paper is another type harmful to septic tanks. In manufacturing, people frequently use glue to hold the layers of thick toilet paper together. These glues are extremely tough to break down and can cause drainpipe blockages.

This implies that thick ply toilet paper might obstruct drains and take a long time to break down the septic system.

Ultra-Soft Toilet Paper

Since the elements included to produce ultra-soft toilet paper are hard to decompose (the reason this paper is very soft), they could cause significant harm to the septic system.

Ultra-soft toilet paper, unlike flushable wipes, is less prone to produce blockages in the sewage pipe since it breaks apart quickly. However, it takes a long time to decompose, making it harmful for septic tanks.

If you use ultra-soft toilet paper for an extended length of time, it might do considerable harm.

Tips To Avoid Buying Worst Toilet Paper For Septic System


Don’t Fall For The Commercials

Stay away from toilet paper that is well-advertised and super soft if you want to safeguard your plumbing. 

The long-term consequences of sending thick tissue along with sewers and into a septic system might reduce the system’s overall effectiveness. It can also cause blockage and long-term harm to streams. Not to mention, they are costly!

Choose The Suitable Brand

Toilet paper labeled “septic safe” is designed for use in septic tanks. Often, unnamed brands produce items that break more easily and do less damage to septic systems. 

Even major firms that offer high-end toilet paper have a limited number of ideal products for your water pipes. Look for items with fewer layers and those created from recyclable materials.

Avoid New Wood Fibers

Avoid items that do not employ recycled materials to conserve trees and your septic tank. If the toilet paper has no post-consumer fiber or low content, you should skip it right away!


It might be difficult to choose the appropriate toilet paper, especially whether you use a septic system. Although sewer systems are rather strong, selecting the wrong toilet paper might result in a significant financial loss in the long term.

Therefore, avoid the worst toilet paper for septic systems: thick, dyed, ultra-soft toilet paper and flushable wipes. Instead, septic-safe toilet paper could decompose rapidly.
