Burger, If the brewing of bacteria for septic system will work I'm all for it. I think I'll even give it a try when my stuff is delivered.
So I take it you're saying that the bacteria count double or triples in a couple of hours?
I did some contracting work at a sewage treatment plant a few years ago and watched, (yes you could actually see)the bacteria working in the tanks. It's pretty amazing how fast they break down the crud. The cleaned water comes off the top and looks like it came from the tap. Don't think I'd want to drink it though. \:D
