Can I empty into a septic system if I use Bio-Pak?

How frequently do I need to use Bio-Pak?

Drop a Bio-Pak down your toilet every time you refill your tank with water after dumping or once you start to smell odors emanating from your toilet. How often you do that depends on usage, but typically campers dump about once a week. After you dump, drop one Bio-Pak packet into five gallons of water for a 40-gallon tank. If you have a smaller tank, we recommend 1.25 gallons of water for every 10 gallons of holding tank area. Adding ample water is crucial because it allows waste and paper to fall below the waterline enabling the enzymes to work their magic.

Yes! Bio-Pak’s powerful enzymes digest paper as well as waste.
