Two types of septic tanks that you can see are the effluent ones and the other is the plastic one. The one that is more famous is the plastic one. The low cost of manufacturing, ease of manufacturing and ease of septic tank installation. These septic tanks can be installed underground as well as over ground. Although over ground septic tanks are not good to look at but they can easily be disguised and also you are left with no option if your ground is unsuitable for underground septic tanks.
Advantages of plastic septic tank
1. The material is more flexible and can withstand some pressure which makes it resilient. This property makes the tanks last longer and fight the cracks better.
2. They are easily movable too. Septic tanks that are suitable for the small homes can easily be moved. This is a big advantage because sooner or later you will have to move it someplace. It might take few people to move it but in case of concrete tank you will be requiring a tank.
3. Plastic tanks due to the ease of manufacturing are cheaper than the concrete ones. And they seem to be the better alternative between the two.
4. There is absolutely no issue of rusting in these tanks since there are no metallic parts available.
5. Plastic tanks do not easily get damaged and remain of great use in waste water treatment until and unless they are severely abused.
