Can you have a garbage disposal with a septic tank? This is a question that many homeowners should ask themselves before tossing food into the sink.

A septic system is a finely tuned piece of equipment that requires maintenance and precautionary measures. Because your septic system is such an intricate device, you should know what’s good for it and what could potentially harm the system.

In this blog, we will answer the question of can you have a garbage disposal with a septic tank and highlight the Do’s and Don’ts of having both a septic system and garbage disposal in the house.

Can You Have a Garbage Disposal with a Septic Tank?

The simple answer is no — you shouldn’t use a garbage disposal if you have a septic tank. This is because all of the fats, grease, and waste will go into the septic tank, which can lead to some serious issues.

Also when you use your garbage disposal, it can overload your septic system and cause some major issues. When there are issues with your tank, it can be extremely costly to repair or replace the system. Plus you will increase the size of your septic and leach field, which also means you’ll have to get your tank pumped twice as often and pay for extra maintenance charges.

What If I Use My Garbage Disposal Anyways?

If you do choose to still use your garbage disposal, knowing it’s not good for your system, then be sure to use it sparingly and properly. The following list of Do’s and Don’ts will help you better understand how to consciously use your garbage disposal so it doesn’t drastically affect your septic system.


  • Use it very sparingly
  • Have your septic tank pumped out more frequently
  • Start a compost pile for excess food


  • Treat it like a trash can
  • Put food, such as egg shells, peels, coffee grounds, pasta, rice, etc. down it
  • Pour oil or grease into the drain
  • Overuse the disposal

Ken and Jamie Starman are the owners of Front Range Septic. They purchased the business in October 2007 after they saw a need to provide quality septic & grease trap pumping services to the Northern Colorado region.

Ken grew up in rural Nebraska, making himself familiar with septic systems. Prior to the owning the septic business, he owned his own custom agriculture business for 22 years. His knowledge of dealing with different types of septic systems and how to properly maintain them has grown over his 10 years of operating the business. He has made it his goal to educate clients on their septic systems to ensure that they are getting their tank properly serviced. In addition, he understands the importance of working with restaurants and facilities that have grease interceptors to prevent costly shut downs due to improper maintenance of their grease traps. He attends wastewater trade shows for continuing education and to keep current with new regulations and trends in the industry. He enjoys the various clients he has worked with over the years and looks forward to continued growth in the future.
