It’s one of the most common questions we get at Davis Plumbing: “Is it okay to have a garbage disposal if I’m on a septic system?” The short answer is yes—but with some very important “ifs.” If you use a standard disposal the same way you would on city sewer, you are fast-tracking your way to a septic system failure.
Here is what Riverside County homeowners need to know about mixing food waste with their septic well.
The Problem with Food Waste
Septic tanks are designed to process human waste and toilet paper, which break down relatively quickly. Food scraps (even finely ground ones) are much denser. They don’t break down as easily, meaning they quickly increase the “sludge” layer at the bottom of your tank. This leads to more frequent septic pump needs and can even clog your inlet pipes.
The “Septic-Safe” Disposal Solution
If you absolutely must have a disposal, look for models specifically labeled as “Septic-Safe.” These units often feature an injection system that adds a dose of enzyme-producing microorganisms every time the disposal is turned on. These enzymes help break down the extra organic matter before it settles in your tank.
Best Practices for 951 Homeowners
- Scrape, Don’t Grind: Use the disposal only for the small scraps left on a plate. Never dump large amounts of vegetable peelings, coffee grounds, or eggshells down the drain.
- Avoid Grease: Never pour fats or oils down the disposal. In a septic system, grease acts like glue, binding food particles together into solid blocks that can ruin your septic system design.
- Increase Pumping Frequency: If you use a disposal daily, you should plan to have a septic tank inspection and pump-out every 2 years instead of the standard 3 to 5.
