What is the primary function of a sedimentation chamber in a septic system?

The primary function of a sedimentation chamber in a septic system is to allow solids to settle. In this chamber, wastewater enters and the flow rate decreases, which provides an environment where heavier solids can sink to the bottom due to gravity. This process is crucial as it helps to separate the solid waste (sludge) from the liquid effluent. The settled solids can then be effectively managed and further treated or removed by the system. This settling process is essential for reducing the amount of solids that can interfere with subsequent treatment processes, such as filtration or biological digestion, enhancing the overall efficiency of the septic system.
