Can Garbage Disposer be used with Septic Systems?

The Answer is YES

How do septic systems work?

A septic system is designed to safely treat and dispose of household waste from the kitchen and bathroom(s). If your system is sized to handle a dishwasher or clothes washer in addition to sinks and toilets, it can handle a disposer as well.

Waste water flows into your septic tank, where solids that are lighter than water (such as grease, oils and paper) float to the top and form a layer of scum. Solids that are heavier than water float to the bottom and form a layer of sludge.

The middle layer of partially clarified water flows through a distribution box that evenly disperses it into your drain field. Gravel and soil then filter out pollutants and bacteria.

Naturally occurring bacteria in your septic tank help to decompose solid matter, but can't take care of it all. That is why, periodically, sludge must be pumped from your tank to keep solid overflow from contaminating your drain field.


Two ways to reduce Sludge in your septic system while using a garbage disposer.


1)    When you choose an InSinkErator Evolution Septic Assist 3/4 HP Continues Feed Garbage Disposal treatment is added to your system with every use. These microorganisms digest both food and household waste inside your septic tank, reducing the accumulation of solids.



2)     A garbage disposer without Bio-Charge and Separate Septic Tank treatments.


Garbage disposers are environmentally responsible because they reduce contributions to Land-fills and greenhouse gasses.  The waste products can be turned into renewable power by waste water treatment plants.  The bio solids can be used as fertilizers by farmers, golf courses and gardeners.


With a disposal in your kitchen, chicken bones, fruit rinds, coffee grounds and more can go right down the drain and into the garbage disposal -- where they're virtually liquefied to safely flow into your sewage system or septic tank. You'll enjoy a cleaner food preparation area, less cans and bags cluttering your home, and fewer trips carrying garbage to the curb.

We were on septic in Orlando, FL and had it pumped, etc.  I asked the plumber about using Rd-X, etc.  He said, "Human waste carries enough enzymes to do the work of taking care of the the waste, no need for Rid-X."  THEN I reminded him my disposer was connected.  He then added, "Well, if you use a lot of processed products (food) then yes, use the recommended Rid-X.  If you are using mostly organic, the system will take care of itself without the additive."

This is based on the plumber in Orlando's recommendation.  It just gives you another opinion to consider.  Things to consider.  Our landscape was extremely porous, so our djainfield emptied with little effort, there were only two of us in the house.  So prep and disposal was not for a constant "family of 4".

Some other factors to consider: 
The use of some cleaning products will affect your system, shampoos, heavily waxed soaps, toilet paper. 
All the things we "drop down the drain" without a second thought (coffee grounds, tea bags, peels, etc.) which would be better composted or dropped in the trash.

Good Luck.
