how to determine the correct septic tank size

A septic tank is present in many homes as an effective, self-contained treatment system that disposes of wastewater in a safe and secure way.

Whilst septic tanks can be stored only a metre away from your home, they are recommended to be held at a further location in order to prevent contamination. Wastewater flows from the home into the septic tank, where it is broken down into three layers on-site and is treated naturally. The three layers consist of the top; solids that are lighter than water, like oil or grease, the middle, which is water that contains chemicals and the bottom; the heaviest solids that form a sludge.

The way a septic tank system works is easy to understand, but many people struggle to determine what size septic tank is right for their home. It’s an important process, as a septic tank that is too small can create extensive problems. You should consider the amount of water you are using within your home, including how much water you use to shower, bathe, clean up or wash your car. A rough guideline is to have a septic tank that can withstand twice the amount of your daily water usage.

You should also consider the amount of people within your household; more people equals more waste. You’ll also need enough space to install a larger septic tank for it to work properly.
