Being a fundamental component in the disposal of sewerage, septic tanks is an on- site sewerage storage unit. With so many sewerage tank varieties available, there are various aspects to look at when deciding which septic tank is best.

Importance of septic tanks

Plastic tanks come with far more long term benefits than any other tank material. Being an alternative septic tank solution to concrete or fiberglass tanks, plastic tanks are often known as “poly septic tanks” as they are made from a combination of polyethylene and plastic. This offers a robust solution and provides various benefits.

  • Less prone to cracking
  • Weigh less than other materials (can be moved)
  • Cheaper
  • Do not rust/ corrosion proof
  • Completely water and air- tight
  • Easy to install
  • Easier to repair than other materials
  • Designed with ribs to add to resilience and strength
  • Manhole extensions and lid risers are easy to install

Plastic septic tanks have become the more common choice due to their ease of manufacturing. Other materials tend to take strain due to pressure, weathering and other factors.

Cement tanks

  • Expensive
  • Difficult to transport
  • Crack under pressure
  • Leak easily
  • Difficult to install

Other septic tank materials such as steel are the least durable as they are prone to rust. Once the rusting process begins, it is nearly impossible to stop, weakening the integrity of the septic tank. This results in the entire septic tank having to be replaced; an expensive replacement considering the material.

Plastic septic tanks are manufactured in various sizes and shapes. To ensure the longevity of your septic tank, plastic is one of the most reliable materials.
