Plastic septic tanks are a great alternative to concrete septic tanks, mainly because they are already premade so the installation process will be done much faster and easier. The first advantage that plastic septic tanks have over concrete septic tanks are that they are cheaper, so if you are on a budget, a plastic septic tank is a great option for you!

Secondly, plastic septic tanks are much lighter than concrete septic tanks, meaning that they are easier to transport and as mentioned previously, they are easier to install. In fact, installation can be as simple as digging a hole, placing the tank and linking it to your plumbing system. This is something that comes in handy because you will be able to install them in a variety of locations.

Lastly, plastic septic tanks are more flexible than concrete septic tanks, meaning that they are more resistant to water based corrosions and they won’t crack as often as concrete septic tanks.

Cons
