Toilet and “Non-Toilet” Paper
A virtual hands-on activity

Toilet and “Non-Toilet” Paper


This lesson was crafted to help students understand why some solids are designed to go down the drain and others are not.

The goal of every Central San lesson is to help students think more critically about “what happens to our dirty water after it goes down the drain?

Want More Wipes Videos?

Our Wipes Fail Flushable Test shows our field testing of 13 different brands of wipes flushed down a 3,000-foot section of sewer pipe. Our results demonstrate that no matter what the label says, wipes clog pipes.

Our Wipes Clog Pipes Commercial is a quick and fun reminder of just how silly it is to flush wipes down the drain.
