A distribution box is a vital component of a septic system. It evenly distributes effluent from the septic tank to the drain field. Its purpose is to ensure that wastewater is evenly dispersed across the drain field area to facilitate efficient filtration and treatment. The distribution box helps prevent overloading of any specific drain field section, promoting uniform wastewater distribution and optimal system performance. Proper maintenance and regular inspections of the distribution box are essential to ensure the overall effectiveness and longevity of the septic system.
