Understanding Septic Tank Sizes

A septic tank in any property is the first stop through which wastewater goes out of a home. This wastewater then stays in the septic tank for some time. During this period, there are a few processes that goes on inside the tank. During this stage, the solids are separated from liquids.

Once done, the solids are filtered out and the rest flows away through the drainage field. However, for all this to happen properly, the size or dimensions of the septic tank is significant. Thus, when installing any septic tank, professionals consider several important facts.

Such factors include:

  • The total square footage of the property
  • Bedrooms in the property
  • Number of people who will be using the property
  • Frequency of guests coming in
  • Frequency of large gatherings, parties or get-togethers

When homeowners get in touch with experts, things get easy. Professionals consider all aspects and then ensure that the right size and dimensions of the septic tank is installed. Also, it’s noted that if there are additional users, the size of the tank should ideally increase by 180 liters for every user.

In Case the Septic Tank is Smaller – What Happens?

The size determines the dimensions of the tank. In case the septic tank is too small and not adequate, several problems will arise. It will not be able to tackle the quantity of wastewater that will exit the property.

If the septic tank is smaller than the required size, then all unpleasant problems might arise. This can be in the form of unpleasant and stinking odors, overflowing of tanks, and blockages.

The biggest problem which might arise due to a small size tank is that the resultant pressure can release liquids before they are filtered out properly. This can be a big problem as the solids will not break down well.

Thus, they will keep accumulating in the septic tank. If this happens, there will be problems with blockages and overflows.


What Happens If the Septic Tank is Too Big?

Just as a small septic tank can lead to several problems, a larger than required septic tank can bring in many problems. An oversized tank will not function well. The wastewater will not flow effectively through it.

In case the septic tank is too large, then there might not be enough accumulation of liquid which can cause build-up of bacteria. Thus, if this happens the solids in the tank will not breakdown properly as the processing will not take place naturally.

It is important to find the right balance when selecting the size and dimensions of a septic tank. This will ensure health and complete hygiene.
