Which System is right for me?

Secondary Wastewater Treatment System

Very high quality water treatment

  • Very high quality treatment of water
  • Ability to reuse your water in areas closer to your home
  • Guarantees to purify all the waste discharges in the tank, before it is discharged to the environment
  • Protects our environment and your family’s health
  • Lower installation cost

Septic System

Lesser quality water treatment

  • Lesser quality water treatment
  • Uses less power
  • Require less maintenance
  • Higher installation costs
  • Effluent cannot be re-used, it must be disposed of through underground absorption trenches

When to choose Secondary Treatment Systems

Advanced secondary treatment systems are the most commonly used systems in Australia. They treat your household wastewater to a very high quality, allowing you to reuse your water in areas closer to your home and neighbouring properties, often above ground, with complete peace of mind. Many councils around Australia are now implementing ‘Septic Changeover’ or ‘Septic Upgrade’ programs, whereby they are asking home-owners with existing septic systems to upgrade them to Secondary Sewage Treatment Systems.

The best choice for the environment will be an Advanced Secondary Wastewater Treatment System, as it guarantees to purify all the waste discharges in the tank, before it is discharged to the environment. The currently available Advanced Secondary Wastewater Treatment Systems purify the water to such a high level that will not cause environmental damage, will not be a danger to humans or animals and will actively assist the environment by recycling all of the water we use in the house to be used again in our gardens.

When to choose Septic Systems

Septic Systems treat the water to a lesser quality than secondary systems, but have the advantage of requiring less power. Effluent from Septic Systems must be disposed of underground through absorption trenches.

A holiday “shack” rather than a holiday “home” may be a suitable site to install a septic system, as there will only be occasional occupancy, probably mains water will not be connected and mains power may also not be available.

Premises such as remote Country Fire Authority or Rural Fire Brigade depots which will only have a toilet and hand washing facilities and are not used regularly except perhaps on training weekends, are also likely sites for a septic tank system.

Things to consider


The Environment

You cannot install a septic tank system in a water catchment area or coastal areas where the effluent can get into estuaries, creeks and rivers and destroy or pollute aquatic life. Many coastal areas have aquaculture or shellfish harvesting, and these have in the past, been rendered unsafe for human consumption by septic tank effluent contaminating the waters.


Size of Land

Small blocks of land may not have enough area available after the house, garage, pool, tennis court, paths and driveways are constructed, for the leach drain area necessary for a septic tank system. Even on a large farm, installing a Secondary Wastewater Treatment System will ensure the aquifers, which may be used for stock or drinking and cooking water in the farmhouse, are not polluted by untreated septic effluent reaching them.


Council Regulations

Any area where the local Municipality demands that “all waste be treated” should only install a Secondary Wastewater Treatment System due to the breaching of the treatment principals of an All-Waste Septic Tank System in such an application.

You may already know which type of treatment system you need. If not, your builder, plumber, or Taylex can help you to find out what will meet the local Council requirements in your area.
