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

The function of a distribution box in a septic system is primarily to distribute the flow of sewage to drain tiles. This component is essential because it ensures that the effluent is evenly distributed across the drainage area, which helps prevent overloading of any single section. An even distribution of sewage prevents wet spots, ensures proper treatment as the effluent seeps through the soil, and promotes effective functioning of the overall septic system.

In a septic system, raw sewage first enters a tank where solids settle at the bottom, and liquid waste flows out. The distribution box intercepts this liquid and plays a crucial role in channeling it to multiple drain field lines, or drain tiles, in a balanced manner. This balance not only enhances the longevity of the system but also helps to prevent the contamination of groundwater and surrounding areas.

This ensures that the wastewater is treated adequately as it percolates through the soil into the ground, where natural processes filter away harmful pathogens and impurities, thus maintaining public health and environmental safety.
