How can clogs be avoided? Clogs can be avoided by careful attention to what types of waste enter the septic system. Grease, for example, can cause a septic system to become clogged. Bacteria does not do a good job in breaking down grease. Therefore, the grease can enter the slotted drains and leach field with enough bulk to clog them.
Paper, other than toilet paper, can also clog up a septic system. If the paper is not broken down before entering the drain field, it can plug up the works.
