If a Garbage Grinder/Garbage Disposal is used, how much larger must the septic tank be sized?

When a garbage grinder or disposal unit is installed in a home, it introduces a higher volume of solid waste and organic material into the septic system compared to a system that does not have such a unit. As a result, the septic tank needs to be appropriately sized to accommodate this increased load.

A 50% increase in the septic tank size is necessary to ensure that there is sufficient capacity for the additional waste materials. This additional capacity is critical because inadequate tank size can lead to inefficiencies in the treatment of effluent and potentially cause system failures, including backups or overflows.

By increasing the size of the septic tank, the system enhances its ability to adequately settle solids and promote effective bacterial action for breakdown, ensuring a reliable and functional septic system that can handle the demands posed by a garbage disposal.
