Where are tank compartment partitions located within the septic tank?

The correct location for tank compartment partitions within a septic tank is typically not less than two-thirds from the inlet end. This design ensures that the settling and treatment processes happen efficiently. By positioning the partition further from the inlet, it allows wastewater adequate time to flow and settle before reaching the outlet compartment. This setup helps in enhancing the separation of solids from the liquid and allows for more effective anaerobic digestion to occur in the first compartment.

Placing the partition towards the inlet end would not provide sufficient space for proper treatment, as the flow would disrupt the settling of solids, leading to potential problems such as improper treatment and increased risks of clogging in the outlet. Therefore, the reasoning behind the two-thirds placement is grounded in optimizing the function and efficiency of the septic system.
