Located at the inlet and outlet of the tank, septic baffles help control the flow of wastewater and prevent solids and floating scum from leaving the tank too soon.

The inlet baffle directs incoming wastewater into the tank to reduce disturbance, while the outlet baffle helps keep solids in the tank and allows properly settled effluent to move on to the next stage of treatment.

Small components like baffles make a big difference in protecting the performance and longevity of a septic system.
