What is a septic tank?

A septic tank, at its most basic level, is a concrete cube that holds wastewater from your plumbing system. Solid materials eventually float to the bottom to create sludge, while floatable matter like oils float to the top as scum. Wastewater is slowly released from the septic tank into a drain field where it is filtered through soil, sand and other organic matter to naturally neutralise and purify it before it is released into the groundwater.

Why is the septic tank I choose important?

Choosing a quality, well-built septic tank is highly important. If your tank becomes damaged, it could lead to plumbing backups or even sewage leaking into your yard. You should also ensure that your tank is large enough to accommodate your home. The size you choose will largely depend on the number of bathrooms and how many people inhabit the home.

Benefits of Concrete Septic Tanks

Compared to plastic septic tanks, concrete tanks have a range of advantages that make them ideal as your wastewater solution. Concrete tanks are rigid and watertight, reducing the risk of leaks over the years. Moreover, with quality concrete your tank can last a lifetime. Other benefits include:

  • High durability
  • They do not rust
  • Less chance of damage during installation
  • Concrete does not have an impact on groundwater quality
  • Unlike tanks made of lighter materials, they do not suffer from buoyancy or 'floating' issues
  • Their weight means that once installed you won't have to move them
  • Concrete septics are fireproof
