What is the function of a distribution box in a septic system?

The function of a distribution box in a septic system is to evenly distribute effluent to the drain field. After wastewater from the septic tank has been treated to remove solids and any harmful pathogens, it finds its way to the distribution box. This component is crucial for ensuring that the treated effluent is directed evenly into the various chambers or trenches of the drain field. By achieving this balance, the distribution box helps prevent overloading any single section of the drain field, which could lead to system failure or backups.

The design of the distribution box allows it to handle variations in flow and pressure, maintaining an even flow across all outlets. This is vital for ensuring the longevity and efficiency of the entire septic system, as it promotes effective absorption of the treated wastewater into the soil. Proper distribution also limits the risk of creating saturated areas in the drain field, which can lead to surface pooling and environmental concerns.
