Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Plastic septic tanks are less durable than concrete ones. | Both plastic and concrete septic tanks have their own advantages and disadvantages, but durability is not necessarily one of them. In fact, some high-quality plastic septic tanks can last just as long as concrete ones. The key factor in determining the lifespan of a septic tank is proper installation and maintenance. |
| Concrete septic tanks are always better for the environment than plastic ones. | While it’s true that concrete is a more natural material than plastic, this doesn’t necessarily mean that it’s always better for the environment when used in a septic tank context. For example, manufacturing and transporting heavy concrete tanks can require significant amounts of energy and resources, which may offset any environmental benefits they offer over lighter-weight plastic alternatives. Additionally, both types of tanks must be properly maintained to prevent leaks or other issues that could harm the surrounding ecosystem. |
| Plastic septic tanks are easier to install than concrete ones. | This misconception depends on several factors such as site conditions (soil type), accessibility to equipment needed for excavation etc., so there isn’t really a clear-cut answer here – sometimes installing a plastic tank might be easier while other times installing a concrete one might be simpler depending on various factors at play during installation process like soil type etc.. However, generally speaking lightweight polyethylene/plastic models tend to be easier to handle due to their weight compared with heavier precast cement models which require specialized equipment for lifting into place during installation process. |
| Concrete Septic Tanks Are More Expensive Than Plastic Ones | Again this depends on many variables such as size required by household needs , location where you live (costs vary regionally) , cost of materials involved in construction etc.. So there isn’t really an easy answer here either – sometimes building with cement will end up being more expensive than using plastic while other times it might be cheaper depending on various factors at play during construction process. However, generally speaking precast concrete models tend to be more expensive due to their weight and the need for specialized equipment for lifting into place during installation process. |
| Plastic septic tanks are less effective than concrete ones. | This is not true – both types of tanks can effectively treat wastewater if they are properly installed and maintained. In fact, some high-quality plastic septic tanks may even outperform their concrete counterparts in terms of efficiency or ease of maintenance. The key factor here is choosing a reputable manufacturer that produces quality products with proven track records. |
