Georgia Septic Installer Practice Test

True or False: All precast concrete septic tanks must have a partition in the middle creating two compartments.

1. True

2. False

3. Only if the capacity is over 1000 gallons

4. Only for residential applications

The correct answer is: True

The statement is true because Georgia regulations require that all precast concrete septic tanks must include a partition to create two compartments. This design enhances the treatment process by allowing for better sedimentation and digestion of solids. In a two-compartment tank, the flow of wastewater is directed from the first compartment to the second, which improves separation of solids from the effluent and reduces the amount of sludge that can be sent to the drain field. This partition not only facilitates a more efficient treatment process but also helps in the anaerobic digestion of organic matter in the wastewater. The requirement for a partition is a regulatory measure aimed at ensuring effective septic system performance, thereby reducing the risk of system failures or environmental contamination. Other options mentioned, such as exceptions based on tank capacity or specific applications, do not align with the established regulations requiring all precast concrete tanks to be designed with this two-compartment structure.
