For homeowners with septic systems, the choice of toilet paper is more than a matter of comfort; it’s a crucial decision affecting the health and functionality of their waste management system. The wrong type can lead to clogs, backups, and costly repairs, while the right kind ensures a smoothly functioning septic system. This article explores the best toilet paper options for septic systems, focusing on biodegradable and rapidly dissolving varieties.

Understanding Septic Systems

A septic system is an underground wastewater treatment structure common in areas without centralized sewer systems. It uses a combination of nature and technology to treat household wastewater from plumbing fixtures (bathroom, kitchen, and laundry). The system includes a septic tank and a drain field (or soil absorption field). For the system to work effectively, everything that goes down the drains must be easily broken down.

The Role of Toilet Paper in Septic Systems

Toilet paper enters the septic system through toilets and is designed to disintegrate in water. However, not all toilet paper is created equal in terms of its impact on the septic system. Some types dissolve more quickly than others, reducing the likelihood of clogging the system and facilitating the decomposition process in the septic tank.

Biodegradable Toilet Paper

Biodegradable toilet paper is specifically designed to decompose quickly. Made from easily breakable fibers, it’s an excellent choice for septic systems. This type of paper is not only septic-safe but also environmentally friendly, as it’s often made from sustainable materials. Biodegradable toilet paper is typically less processed, meaning fewer chemicals are involved in its production, which is beneficial for both your septic system and the environment.

Rapidly Dissolving Toilet Paper

Rapidly dissolving toilet paper is another ideal option for septic systems. As the name suggests, it breaks down quickly when flushed, reducing the risk of clogs and backups. This type of toilet paper is thinner and has fewer layers, which facilitates faster disintegration. It’s especially suitable for homes with older septic systems or those prone to problems.

Factors to Consider When Choosing Toilet Paper for Septic Systems

  1. Dissolvability: The quicker a toilet paper can dissolve, the better it is for the septic system. Tests can be conducted at home by placing a sheet of toilet paper in a jar of water and shaking it to see how quickly it breaks down.

  2. Thickness: Multi-ply toilet papers might offer more comfort but can take longer to break down. Two-ply are often better suited for septic systems.

  3. Chemical-Free Options: Toilet papers that are free from dyes, fragrances, and other chemicals are preferable. These chemicals can disrupt the microbial balance in the septic tank, which is essential for breaking down waste.

  4. Recycled Materials: Toilet papers made from recycled materials can be a good choice. They not only support environmental sustainability but also tend to be more septic-friendly.

Recommendations and Maintenance Tips

  1. Choose septic-safe brands: Many brands label their products as ‘septic safe.’ These are tested and proven to break down quickly.

  2. Avoid flushing other products: Only human waste and toilet paper should be flushed. Even products labeled as ‘flushable,’ like certain wipes, can harm the septic system.

  3. Regular maintenance: Regularly inspect and pump your septic tank as recommended by professionals to prevent any long-term issues.


The selection of toilet paper can significantly impact the health of your septic system. Opting for biodegradable or rapidly dissolving toilet paper can save you from the headache of dealing with septic system problems. By considering factors like dissolvability, thickness, and the absence of harmful chemicals, homeowners can make informed choices that benefit both their septic systems and the environment. Remember, what goes down your toilet has a lasting effect, so choose wisely!
