These bacteria are the same ones which are naturally present in the human digestive tract. Simply using your toilet is all you really need to do to keep supplying your septic tank with the bacteria it requires. You should never drive over your septic tank. The new ADEQ rules prohibit driveways over disposal areas and septic tanks, regardless of whether the driveway is paved or not. Save the dog food and the chicken.
Septic systems work with bacteria, which are naturally present in human waste.
You need only start using your toilet in order to give your septic tank all it needs to do its job. DO NOT drive over your leach lines or tank. DO NOT allow anyone to dispose of grease, oils or chemicals into your septic system. Septic systems simply cannot dispose of oily materials and they can ruin your disposal field. Harsh chemicals can harm the bacteria in your septic tank and can create environmental contamination if disposed of in your septic system.
