Created specifically for homes with septic systems, the Evolution Septic Assist delivers the new standard in sound and grind performance. Insinkerator’s powerful food waste disposers are the right choice when replacing an existing unit or designing a brand-new kitchen. You can choose between five Evolution models, including Evolution Compact, designed specifically for homes with restricted cabinet space.

With an InSinkErator food waste disposer in your kitchen, chicken bones, fruit rinds, coffee grounds and more can go right in the sink -- where they're virtually liquefied to safely flow into your sewage system or septic tank. You'll enjoy a cleaner food preparation area, and less bagged garbage cluttering your home.

What's more, if you've never owned a food waste disposer, you're in for a pleasant surprise. InSinkErator disposers are economical to operate: in fact, they're among the least expensive installed kitchen appliances.

  • newegg Less Noise With InSinkErator's SoundSeal noise-reduction technology, the Evolution Septic Assist is at least 40% quieter than standard disposers.
  • newegg More Volume 40-Ounce Stainless Steel Grind Chamber and Grind Components handle more volume than standard disposers.
  • newegg Enhanced Speed Bio-Charge Injection Technology utilizes a natural microorganism to help break down food waste. 3/4 Horsepower Dura-Drive Induction Motor gives you more horsepower than standard disposers. MultiGrindTwo grind stages let you quickly grind difficult food waste you wouldn't put in a standard disposer, like celery and potato peels.
