InSinkErator Evolution Series 3/4 HP Septic Assist Garbage Disposal

Designed specifically for septic systems, the Evolution Septic Assist features Bio-Charge, an automatic injection of micro-organisms to help break down food waste. 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.


  • MultiGrind two grind stages let you quickly grind difficult food waste you wouldn't put in a standard disposer, like celery and potato peels
  • SoundSeal makes the Evolution Septic Assist at least 40% quieter than standard disposers
  • 40-Ounce stainless steel grind chamber and grind component handles more volume than standard disposers
  • Bio-Charge injection technology utilizes a natural micro-organism to help break down food waste
  • Evolution Series collection
  • 3/4 Horsepower Dura-Drive induction motor gives you more horsepower than standard disposers
  • Full 4 year parts and in-home service warranty

About the Manufacturer

In 1927, Insinkerator, the world's first food waste disposer was created a few blocks from their current World Headquarters. Racine architect John W. Hammes came up with the idea, perfected and patented it, and founded the company that from day one has been the world's largest manufacturer of disposers.

Much of Insinkerator's growth is due to their committed partnership with plumbing contractors. Since the 1940s, InSinkErator® has been the first choice of plumbers, builders and kitchen dealers with good reason: it's the reliable brand they can install and literally forget. In addition, Insinkerator products are readily available on the internet.

As the best-selling food waste disposer brand in the world, millions of InSinkErator® disposers are manufactured annually. Insinkerator is also the leading brand of instant hot water dispensers and point-of-use water heaters. Today, InSinkErator® has operations in over 80 countries worldwide.

Questions & Answers (1)


“How is this Biocharged Do you have to add any extra products to assist the disposal for septic systems” asked by Terry

"This comes with bio-charge injection technology but you would need to purchase this bio-charged solution separately with SKU INK1011. This solution has components in it that will break down tough grease and other things that a normal disposal would have a hard time taking in." Tyson from Wayfair

septic bonanza

from Palo Cedro, CA – Verified Buyer

Very quiet and effecient disposal. As a bonus when chopping waste, the disposal adds a shot of septic food. No more $400 septic pump outs.
