If you are in the market for a new septic tank, you may be wondering whether to choose a plastic or concrete model. Both have pros and cons, so it can be challenging to decide which is suitable for your home. In this blog post, we will compare and contrast plastic and concrete septic tanks so that you can make an informed decision about which one is best for you!
Plastic Septic Tanks
These types of septic tanks have become a popular alternative to concrete tanks. They come pre-made in an oval shape and have ridges on the exterior walls.
Pros:
- They are lightweight and easy to transport: Plastic septic tanks are much lighter than concrete tanks, making them easy to transport.
- They are cheaper: Plastic septic tanks are typically more affordable than concrete tanks. This is because they are mass-produced and made from less expensive materials.
- They can be installed quickly and easily: Plastic septic tanks can be installed quickly and easily because they come pre-made in an oval shape. A single person can also easily install them, whereas concrete tanks require multiple people for installation. There is no need to excavate a hole for the tank, as you would with a concrete tank.
Cons:
- They are weaker: Plastic septic tanks are not as strong as concrete ones. This is because they are made from thinner plastic and are not reinforced with steel or concrete. This means that they are more likely to crack or collapse if there is too much weight on them, such as from a heavy vehicle driving over them.
- They have low effluent levels: To function properly, a septic tank must have the right balance of sludge/solids, effluent/water, and scum/lightweight solids. The effluent levels in plastic septic tanks are lower than in concrete ones. This is because the plastic does not allow for as much water to be stored in the tank. As a result, the effluent level will rise more quickly and need to be pumped out more often.
- They require more maintenance: Plastic tanks will need more maintenance than concrete tanks. This is because they are more likely to crack or collapse, and the effluent levels in them will rise more quickly. As a result, you will need to pump out the tank more often.
Concrete Septic Tanks
A concrete septic tank is a traditional option that offers two different choices: pre-cast or poured-in-place. The pre-made tanks can be installed immediately after arrival, while those who have the latter option need to dig up dirt and create a mold for their structure before they’re ready!
Pros:
- Durable: Concrete septic tanks are much more durable than plastic ones. They can last for decades, whereas plastic tanks will only last for a few years. Concrete tanks can be easily driven over.
- Low maintenance: Concrete septic tanks require less maintenance than plastic ones. This is because they are not as likely to crack or collapse, and the effluent levels can be easily monitored.
Cons:
- More expensive: Concrete septic tanks are more costly than plastic ones. This is because they require more materials and labor to construct.
- Heavy: Concrete septic tanks are much heavier than plastic tanks. This makes them difficult to transport and install.
- More difficult to repair: Concrete septic tanks are more difficult to repair than plastic tanks. This is because they require special skills and tools to fix.
