Septic tanks come in different sizes and shapes. The size and shape of the tank are usually dependent on how big the household is. If you’re living together with your family and some extended family members, such as the maternal grandmother or paternal grandfather, then you’ll need to make sure that your septic tank can hold in the wastes coming from the toilet altogether. For a house with a big household living in it, a cement septic tank is a better choice.
The cement septic tank is usually embedded or dug underneath the ground. The tank itself is made from cement, so there are fewer chances of the tank getting leaks due to natural wear and tear. And because it is made of concrete, it is better to withstand natural wear and tear compared to other septic tanks. In fact, the cement septic tank can last centuries if it is drained and maintained properly.
Cement septic systems have always been popular and in the past, before plastic and fiberglass, the concrete tanks were the only option around. One of the reasons this type of tank is seen so much is because it can withstand the test of time. A properly constructed cement tank will last for half a century or more. However, if the cement is not mixed or poured properly it may only last a few years. Buying from a reputable contractor is essential.
Concrete septic tanks are very heavy, even when empty. This means that they will not float in the ground and rise out of the ground over time as a plastic tank does sometimes.
The concrete septic tanks are recommended for large households because they can be built to be quite large. In fact, they can be poured to almost any size, but the larger the cement tank, the heavier it will be and the bigger the crane required to install it. A plastic tank, the same size as a cement tank, is only a fraction of the weight.
In conclusion, make sure that you do your homework and find the best tank for your needs. Depending on where you live and how large your household is you may be able to choose from cement, plastic or fiberglass tanks. Do not take your decision lightly because septic problems after the septic system are installed can give you gray hairs. There are a lot of free resources online and any local contractor would be happy to help you make the best choice.
