A septic tank separates wastewater components, the first process of conditioning a waste disposal system that occurs in the subsurface.
A septic tank is usually sized to the number of bedrooms the home has and will have pumped roughly every three years, depending on usage. These tanks are built to be watertight and are most often made of concrete, fiberglass, or polyethylene. You can also get installed concrete septic tank via https://ecoseptic.com.au/septic-tanks/
Heavy solids that enter the tank settle to the down, create mud and grease, oils, along with lighter solids float on the top creating a layer of scum. The area between the two layers contains wastewater flowing through the baffle outlets in the septic tank drainage fields.
Anaerobic and facultative microorganisms eat the solids from the sludge zone and a layer of scum in the tank, breaking down the volume. Because not all mud and debris in the septic tank is broken, the tank needs to be pumped out periodically.
If left on for a long time without pumping, solids will eventually build up and fill the tank, causing these solids to exit the tank and clog drainage field. Once the solids have entered the field drainage, it would limit the ability of soil to seep liquid waste efficiently, causing the system to fail.
The three functions of a septic tank, solids separation, bacterial action, along with mud and trash storage which is very important in producing treated wastewater to discharge into the washing or drainage field.
