Plastic Septic Tanks

The Advantages: There are many advantages to using a plastic septic tank over a concrete septic tank, which include, but are not limited to:

  • Plastic septic tanks are very resistant to cracking, unlike concrete.
  • Rusting is a non-issue.
  • As plastic weighs less than concrete, it is much easier to get a plastic septic tank into the location for installation.
  • A plastic septic tank is more cost-effective than a concrete septic tank.

Plastic septic tanks can be water-tight and corrosion proof.

The Disadvantages: There are many advantages to using a plastic septic tank over a concrete septic tank, which include, but are not limited to:

  • Plastic septic tanks tend to have lower effluent levels, which may be discovered after a tank is opened for pumping.
  • If not installed properly, a plastic septic tank can "float" to the surface of the ground.
  • Because plastic is such a light-weight material, it can be damaged at installation.
  • Plastic septic tanks are not approved in all states.

When is a plastic septic tank appropriate? Plastic septic tanks can be the right choice when they are permissible in your state and when cost is a significant consideration. In the end, you must decide if a plastic septic tank is best for your project.

Concrete Septic Tanks

The Advantages:

  • Concrete septic tanks have higher effluent levels than plastic septic tanks.
  • Because concrete septic tanks are heavy, there is no chance of floating, unlike plastic septic tanks.
  • Concrete septic tanks are long lasting and extremely durable.
  • These septic tanks are approved in all states.

The Disadvantages:

  • Concrete septic tanks are very expensive.
  • These septic tanks can crack under extreme circumstances.
  • Because concrete is heavy, it is very difficult to install.
  • Though concrete septic tanks are very durable, they can crack and are more susceptible to leaks.

When is a concrete septic tank appropriate? When concrete is mandated by zoning codes, concrete septic tanks are appropriate. Additionally, septic professionals choose concrete when value is a more important consideration than cost.
