Sewage treatment processes are essentially the same all around the world. The system relies heavily on bacteria to process the solids and liquid portions of the waste.

There are two main types of waste control or septic systems available in South Australia - the conventional system and aerobic systems. There are also a range of other systems available, such as composting toilets, reed beds etc however these systems are currently classified as non-complying and as such require approval from the Department of Health (DH) and not the local Council. If you are looking to install a non-complying system then you should direct all inquiries to the Department of Health (SA).

Septic System Anatomy

A septic tank, the key component of a septic system, is a small scale sewage treatment system common in areas with no connection to main sewage pipes provided by private corporations or local governments.

Proper design, installation, and maintenance of your septic system will maximize your system's life. It will prevent failures that can be unsightly, foul-smelling, and threatening to your family's health. Good maintenance reduces the risk of contaminating your well water, and may save you from costly repairs or system replacement.

Untreated household sewage will quickly clog all but the most porous gravels if applied directly to the soil. The function of the septic tank is to allow separation of the solids from the sewage so that the remaining liquid (effluent) can be absorbed into the ground without clogging the soil.
