Can You Use a Garbage Disposal With a Septic Tank?
SOME THINGS YOU CAN’T DO YOURSELF
CALL THE PROS
If your home in Ashtabula County, Ohio, relies on a septic system, you may wonder whether it’s safe to use a garbage disposal. The short answer is yes—but only with care. Garbage disposals can add convenience to your kitchen, but improper use can create serious issues for your septic system.
How a Septic System Works
A septic tank separates solids and floating matter, like oils and grease, from wastewater leaving your home. Solids settle at the bottom, while lighter materials rise to the top. Beneficial bacteria in the tank help break down some of the waste, but not everything. Over time, these layers of sludge and scum reduce the tank’s capacity, which is why regular pumping is essential.
Using a garbage disposal adds ground-up food waste to the solids layer, increasing the workload for the bacteria. Frequent use of a disposal can lead to more rapid accumulation of solids, meaning your septic tank may need more frequent inspections and pumping—sometimes twice as often.
What Not to Put in a Garbage Disposal
To protect your septic system, only put food waste down the disposal. Avoid:
- Fats, oils, and grease
- Non-food items like toys, nuts and bolts, or utensils
- “Flushable” wipes or paper towels
Flushing these materials can cause clogs, damage your disposal, and create backups in your septic system.
Septic-Safe Garbage Disposals
Some manufacturers offer disposals labeled “septic-safe,” often marketed with enzymes or chemicals to help break down solids. However, there’s little evidence that these additives are beneficial, and they can even disrupt the natural bacterial balance in your septic tank.
