Can a Garbage Disposal Be Used with a Septic System?

In this blog post, our professionals from Septic Blue will take a detailed look at how garbage disposals interact with septic systems and the best practices to ensure your system remains efficient and effective.

Understanding Septic Systems

Septic systems are underground effluent treatment structures that are self-contained. They are typically composed of a soil absorption field and a septic tank. Wastewater from your home flows into the septic tank, where solids settle to the bottom, forming sludge, while oils and grease float to the top, forming scum. The liquid (effluent) is subsequently expelled from the vessel and is subsequently treated by the soil in the absorption field.

The Function of a Garbage Disposal Facility

A garbage disposal is a convenient kitchen appliance that grinds up food waste into small particles that can be washed down the drain. Although convenient, the use of a waste disposal in conjunction with a septic system can result in complications if not managed properly. The additional food waste can increase the amount of solids in your septic tank, which can lead to more frequent septic tank pumping.

Impact on Septic Tank Pumping

Food waste from a garbage disposal can contribute significantly to the volume of solids in a septic tank. A septic company typically recommends pumping every 3-5 years, but with a garbage disposal, you might need more frequent service. Regular pumping is crucial to prevent sludge buildup, which can cause blockages and reduce the efficiency of the system.

Considerations for Septic Tank Repair

Additionally, the use of a garbage disposal without proper precautions can result in the need for septic tank repair. Food particles may infiltrate the absorption field and produce blockages if they are not sufficiently digested. Backups may result from these obstructions, necessitating costly repairs. Therefore, it's essential to ensure that your garbage disposal grinds food waste into very fine particles.
