Outfit your facility restrooms with classic Cottonelle® comfort. The strong, 2-ply is strong and effective, designed septic-safe for all standard sewers and septic systems.

1-ply toilet paper In general, 1-ply toilet paper is the type recommended by plumbers. Even if you end up using more to counteract the thinner composition, 1-ply paper still breaks down faster. And that's the key to preventing toilet paper from clogging your pipes.

For septic system use, you want toilet paper that's strong and absorbent but also will break down quickly into small particles. One-ply paper is the best, but many consider two-ply a good compromise. It is usually strong and soft enough for good performance and better suited to breaking down.

Thicker toilet paper is also more prone to causing clogs when flushing. For septic system use, you want toilet paper that's strong and absorbent but also will break down quickly into small particles. One-ply paper is the best, but many consider two-ply a good compromise.

3 or 4-ply Toilet Paper The extra layers of paper in a 3 and 4-ply toilet roll require more water to flush them away. The paper is also much thicker, meaning it's more likely to clog.

We recommend Scott Rapid-Dissolving Toilet Paper for its fast-dissolving and septic-safe properties combined with softness and sustainability. We recently tried out the Scott Rapid-Dissolving Toilet Paper, and we were impressed by how quickly it dissolved.

Use chemical products that are safe for septic systems. Use vinegar, baking soda, and hot water.
