If a septic tank will have a garbage disposal unit feeding into it, what should be done?

When a septic tank is designed to accommodate a garbage disposal unit, it is essential to increase the tank size. Garbage disposals introduce a significant amount of organic waste that is not typical for household sewage. This additional waste can lead to an increased volume of solids and grease, which the septic system must accommodate and break down.

By increasing the tank size by 50%, the system is better equipped to handle the extra load, allowing for adequate settling and anaerobic digestion, which are crucial for effective wastewater treatment. An appropriately sized tank helps prevent premature failure of the system, potential backups, and environmental contamination.

This adjustment ensures that there is enough capacity to handle the increased waste load, maintaining the overall efficiency and functionality of the septic system. Proper sizing is essential to ensure long-term operation and compliance with environmental standards.
