Septic tanks give the same benefits but the types of septic tanks there are is night and day. You’ve probably seen concrete and plastic septic tanks, regardless of whether you’re looking to install a new septic system or replace an existing one.
Many homeowners don’t like the idea of spending large amounts of money on something that manages wastewater. This is a major investment that should not be taken lightly. Each has its pros and cons, and we hope this helps you make a decision on the types of septic tanks you would want to install.
Plastic Septic Tanks
These types of septic tanks are becoming an increasingly popular alternative to concrete tanks. They come pre-made in an oval shape and have ridges on the exterior walls.
Pros
- Easy to Install and Lighter
These types of septic tanks are lightweight because they are made from plastic. They typically weigh in at least 100 pounds and can easily be moved with a regular truck. It is therefore much easier to install and less expensive. It is as easy as digging a hole, placing the tank, and connecting it with the rest of the system.
- Cheaper
Plastic septic tanks can be lighter and more straightforward to install than concrete tanks. These savings are usually the greatest in terms of installation costs, but they can also be used to save money on the tank.
Cons
- Weaker
Concrete septic tanks can be stronger than plastic ones. Driving anything on top of the tank could cause it to crack or be damaged. Plastic septic tanks can also be damaged by environmental factors like soil vibrations or root penetration, which could cause cracks or warping. This damage can sometimes be repaired, but depending on the severity of the problem, it may be necessary to replace the tank.
- Low Effluent Levels
To function properly, septic tanks must have the right balance of sludge/solids, effluent/water, and scum/lightweight solids. The plastic septic tank is lighter and can’t handle as much effluent as a concrete one. It can cause flooding in your system, causing the tank to “float” on the soil. This could damage the plumbing lines around the tank.
- Require More Maintenance
Plastic septic tanks are less able to handle high levels of effluent than concrete tanks and require more regular maintenance. To prevent the buildup of effluent, you will need to clean them more often. This is an important aspect to consider when calculating the total cost of each system.
Concrete Septic Tanks
Concrete septic tanks offer a traditional alternative. There are two options: have a pre-cast concrete tank delivered to you, or have it poured in your place. Premade tanks can be installed immediately after they arrive. For the poured-in-place option, you will need to dig a hole and create a mold in order to form your tank.
Pros
- Durable
Concrete septic tanks last longer than plastic ones. Concrete septic tanks can be easily driven over. This is not true for the lines that lead to or from the tank. Be careful.
- Low Maintenance/High Effluence
Concrete septic tanks can handle large amounts of effluent because they are very heavy. Concrete septic tanks require less maintenance than plastic.
Cons
- Heavy/Expensive
Concrete septic tanks are heavy. They can weigh up to several tons, depending on the size of your home. These heavyweights require heavy machinery to transport and install. This will result in higher overall costs.
- More difficult to repair
Concrete septic tanks are less susceptible to being damaged by environmental factors like soil vibrations and root penetration. If they are damaged or cracked, however, it can take longer to repair the tank over plastic tanks.
