We have been in our house on septic for 10 years, use Charmin every day and have never had a problem. We were in our previous house 8 years, used Charmin every day, never had a problem. Please don't use too much ( however, I am a "wadder" not a "folder" so I'm sure I use more than some people!) and make sure to flush thoroughly. Don't put anything down your drain that is greasy (such as in garbage disposals) or that can kill the bacteria. For those folks who recommend Rid-X, I have to say that the only people o ever knew who had septic problems used Rud-X religiously -- coincidence?!
