In general, a septic system is composed of an underground reservoir called a septic tank and a drainage system which can be either in the form of a leaching field or a treatment system.

The purpose of the septic tank is to collect waste from, for example, toilets, washbasins and showers of a house. The solid particles are collected by sedimentation in a septic tank while the liquid flows into the ground by means of the drainage system. This type of installation is found in areas where there are no local authority serviced sanitary sewers.

The septic tank is normally divided into two compartments: one side for solids and one for liquids. The sludge solids suspended in the wastewater settle to the bottom of the septic tank, where they form a layer. Fats and other light materials remain on the surface of the septic tank and form a layer of scum.

The sludge stays in the first compartment of the tank until it is next emptied. Liquids pass into the liquid compartment of the septic tank before flowing into the leaching field or the sewage treatment system. In short, the septic tank serves to trap and store solids and fat while ejecting the liquid through the drainage system.

The septic tank requires regular maintenance. The solids and grease accumulate and need to be pumped periodically. If the tank is not drained, solids will eventually get into the drainage system making it totally ineffective. It is important to drain the septic tank according to the requirements to avoid this kind of problem.

The bacteria in wastewater are vital because they help to reduce the volume of sludge and minimize the frequency of cleaning. After draining, it is strongly recommended a thin layer of sludge be left in the bottom of the pit in order to regenerate the bacterial flora.

In the case of selective emptying, after draining the water is returned to the pit, which contains enough bacteria to satisfy the most demanding pits, and is free!

Here are the 3 steps for the selective emptying of a septic tank:

  • Drain the water compartment of the septic tank
  • Drain the solids compartment
  • Place some of the water (with bacteria) into the solids compartment
  • For details on the operation of the septic tank, check this diagram.
