Septic Tank Shape, Size & Dimensions With Table


Septic Tank Shape, Size & Dimensions:

Septic tank is a devise which deals with the sewage from water closets. In other words, it is a watertight single-storeyed, underground tank in which sewage is retained sufficiently long to permit sedimentation of suspended solids and practical digestion of settled sludge by anaerobic bacterial action.


Shape Of Septic Tank:

The simplest form of a septic form is a single compartment, rectangular or cylindrical in shape. The shape of septic tank influences the flow speed of wastewater and sludge accumulation.

The dimension of the septic tank should not be too deeper too shallow. Because it can cause short-circuiting of the inlet and outlet flow.

Septic tank having a greater surface area with sufficient depth should always be preferred.

Rectangular shaped single compartment tank (with length three times of its width) is more favorable.

In some cases, cylindrical shape with suitable size is also sound to be a better choice.
