Living in the country with a septic has posed a challenge to having the luxury and efficiency of a garbage disposal to truly complete my kitchen. After hearing about the Septic Assist from a family member (also a licensed plumber), I was thrilled to know that Insinkerator was the brand to stand behind it as well. I've had Insinkerator disposals before and they are second to none in longevity, durability, power and QUIET. Thrilled with my new Septic Assist. Easy to install and the replaceable Bio Charge cartridges (bottles) are simple to swap out and last a long time. If you use this correctly (and don't shove whole pumpkins down your disposal -- as no one, even on utility water should!) you too will have no issues with having a garbage disposal AND a septic tank.
