How Does a Septic Tank Work?

Posted by Callum Vallance-Poole, on July 10, 2024.

A septic tank is a holding tank for wastewater. It separates the sludge through baffle walls and allows the settled sludge to remain in different chambers. The liquid waste is discharged through an outlet into a drainage field, following the code of practice. Upgrading from a septic tank that discharges into a watercourse is recommended. The treatment process primarily involves the settlement of sludge and extracting water while preventing solids and scum from reaching the drainage field. This helps maintain the drainage field’s lifespan and keeps the sludge inside the tank.
