I have a septic system also and when I got it pumped out when we first moved in, I asked the person who was pumping out our septic if it was wise to put in a garbage disposal. This person said no because the food and grease that you put down in your septic system will destroy the pipes and put toxins in your ground water. You do not need to do this because if you have ground water like we do actually free water you do not need to poison your water source.
