What is the primary function of the septic tank baffles?

The primary function of the septic tank baffles is to direct wastewater flow and prevent scum exit. Baffles are important structural components within a septic tank that serve several critical purposes. First, they help manage the flow of wastewater as it enters the tank, guiding it down into the tank while allowing settled solids and scum to remain in their appropriate layers. This helps ensure that the effluent is properly separated from the solids and that the scum—comprised of lighter materials that float—remains on the surface.

Additionally, by controlling the flow, baffles prevent scum from moving into the outlet and potentially clogging the drainage field or leach field. This flow management prolongs the life of the septic system and ensures its effective operation, preventing contamination and minimizing the risk of system failure. By performing these functions, baffles play a crucial role in the overall treatment process that occurs within septic systems.
