Proper disposal of solid waste is one of the primary responsibilities of a civilized society. And one of the most widely used techniques to do this besides the sewer system is the septic tank system!
There are 27 million households in the US that operate on a septic tank; however, only a fraction of them use theirs with a garbage disposal!
That's because most homeowners mistakenly believe that a garbage disposal is bad for a septic system, and the two aren't compatible.
So, if you want to know more about improving your waste disposal system, read on!
A Garbage disposal unit is a useful addition to your kitchen. It is designed to incinerate food waste, so it seamlessly passes through the sink drain.
They typically shred to under 2mm so that every fragment can pass through plumbing without damaging the drainage system.
These units are more convenient than trash cans as they divert food scraps from landfills. They are also easy-to-maintain and operate.
However, if not cared for, garbage disposals can clog up and emit a foul odor.
What Does A Septic Tank Do?
A septic tank (underground water-tight container) is similar to the sewer system. It gets waste from the house and decomposes it through bacterial activity. Then it diverts the liquid waste into the drain field.
It can easily contain a volume of 1000 gallons (3785 liters) of water.
Septic tanks are build from safe and durable materials like concrete. They can last between 26 to 31 years with proper maintenance and offer an accessible substitute to the standard sewer system.
However, they require pumping after every few years. Otherwise, they won't function properly and eventually halt entirely because of the accumulated sludge.
Can Garbage Disposals Be Used With Septic Systems?
You're here because you want to know the answer to the question: Can you install and use the garbage disposal with a septic tank?
Well, the answer is a big YES!
However, several precautionary measures need to be taken to ensure that the garbage disposal doesn't disrupt the septic tank's functionality.
A septic tank separates solids and other floating matter from wastewater. The floating particles reach the top whereas, solids sink deep.
As the floating sludge and scum increases, the septic system's capacity decreases. Meanwhile, the bacteria will help decompose parts of the solids, however not all, which is why a septic tank needs to be pumped regularly.
When you use garbage disposal along with a septic system regularly, the amount of overall waste that flows into your septic system dramatically increases.
As the natural bacteria won't decompose all of the solids quickly enough, the septic system requires more inspection and pumping.

People also Ask (FAQs)
What is the difference between a septic tank system and a sewer system? Is one better than the other?
In the septic tank system, your waste flows into a tank where bacteria decomposes solids, and the liquid waste is released into a drain field. In the sewer system, the debris flows directly to a treatment facility through sewer lines, removing contaminants before discharging water back into the local water supply.
What are the disadvantages of a septic tank garbage disposal?
Some of the most common disadvantages include a clogged tank or field pipes, costly regular pumping (every 3 to 6 years), and drainage pipe leaks that cause an unpleasant odor.
Can You Use An Insinkerator With A Septic Tank?
Yes, you can! If you use your septic system with a clothes washer or a dishwasher, it can easily handle InSinkErator disposers as well.
What is the best garbage disposal for septic systems?
