There are several factors to consider when using a garbage disposal or grinder in a home with a septic system. Although these units can be handy, they can also put additional strain on your septic system and result in the need for more frequent septic tank pumping and maintenance. It is important that homeowners understand the effects putting more solid waste down their drains, even when ground through a disposal, will have on their septic system performance and maintenance.
Negating The Impact Of A Garbage Disposal
Garbage disposals may grind or breakdown food solids into smaller pieces, but they do not dissolve these particles. The impact of increasing the flow of solids into your septic system will change how well it’s able to perform. If you are using a garbage disposal, you can minimize this negative impact on your septic system by taking the necessary steps.
- Increasing the frequency of septic tank pumping. With more solids in your septic system, your tank may need to be cleaned more often to maintain an efficient level.
- Monitoring foods and solids that are put into garbage disposal. Keep items which will be difficult to breakdown in the septic tank out of the garbage disposal. Avoid grease, oil, coffee grounds and tougher items like egg shells or produce peels.
- Using additives. There are enzymes which can be used with garbage disposals to enhance the ability for solids to breakdown in the septic tank. It is important to talk with your septic professional to ensure that these additives are safe for your individual septic system.
Ideally, to save on pumping and maintenance, putting minimal solid food down your drains, even if through a disposal, is best for your septic system. However, if you are considering adding or already have a garbage disposal, discuss the best options for maintenance with your septic professional.
