What is the importance of a septic system’s outlet filter?

The outlet filter in a septic system plays a critical role by preventing solids from entering the drain field. As wastewater exits the septic tank, the filter captures larger particles and debris, ensuring that only clarified effluent moves into the drain field for further treatment. By performing this function, the outlet filter helps maintain the health and efficiency of the drain field, preventing clogs and backups that can lead to system failures or environmental contamination. This is essential for the longevity of the septic system and for protecting groundwater and surrounding environments from potential pollution.
