How do septic tanks work? – Video Transcription

Mark Ward:

“Generally speaking, a septic tank can be described as a separating device. So all of the waste from a property flows into it, and then the internal design of the tank is effectively set to retain the sewage and allow the liquid to overflow.

So it’s a separating device, retains the solid matter. The liquids flow pass the baffles or the dip pipes, and then exit the tank. But that effluent is not treated, so the effluent can only be discharged into the ground.”
