Cesspool and septic tanks are used when the property is not connected to main drainage ie the effluent does not go into the public sewer.

Cesspool

This is a covered pit into which raw sewage is discharged. Cesspools have to be emptied periodically and this is carried out by private waste contractors.

Septic tank

This is a watertight reservoir or tank that receives sewage and by sedimentation and bacterial action affects a process of partial purification.

The maintenance of both a septic tank and a cesspool is the responsibility of the property owner.
