How Much Does A Septic System Cost In Australia?

Septic tank systems are a popular choice for waste disposal in many parts of Australia. They effectively treat and dispose of human and organic waste, so that it does not contaminate groundwater or surface water.

In this post, we’ll explore how much a septic system typically costs in Australia and the factors that affect this.

The exact cost of a septic tank system installation in your area will depend on a number of factors, including:

  • The size of the tank
  • The type of tank used
  • The cost of materials in your area
  • The distance between the tank and the house
  • Whether a leach field is required

The size of the tank

Septic tank systems come in a wide range of sizes. A small tank that holds 200 litres costs about $1.50 per litre, while a large tank that’s 500 litres costs about $1.30 per litre. Therefore, the larger the tank, the cheaper the cost per litre. Some tanks are made with concrete while others are made with polyethene. Concrete tanks require more capital costs to install, but they have a longer lifespan.

The type of tank used

A septic tank system can be made from a variety of materials. These include:

  • Concrete
  • HDPE (High-Density Polyethylene)
  • Polyethylene
  • Plastic

The cost of materials in your area

The cost of materials for a septic tank installation will depend on the cost of living in your area. Materials like concrete are a viable option due to their durability, strength and post maintain service.

The distance between the tank and the house

Some tanks are buried close to the house, while others are buried further away. The cost of a septic tank installation will be lower if the tank is buried close to the house because it will be cheaper to lay pipes.

Whether a leach field is required

The cost of a septic tank installation is usually a one-off payment. This is because most septic tank systems are buried underground and do not need maintenance. An exception to this is in areas that are experiencing higher rainfall, which is when a leach field is required. A leach field is a system of perforated pipes that are installed in the ground to collect wastewater from the tank. This wastewater can then be used to water your garden. The average cost of a leach field is around $1500 to $3000.
