Plastic tanks are less prone to cracking since plastic is flexible, and thus a plastic septic tank does not crack as much as a cement septic tank. Plastic septic tanks are more hygienic than cement tanks.
How do plastic septic tanks work?
Septic tanks work by allowing waste to separate into three layers: solids, effluent and scum (see illustration above). The scum, composed of waste that’s lighter than water, floats on top. The middle layer of effluent exits the tank and travels through underground perforated pipes into the drainage field.
What are plastic septic tanks made of?
about septic tanks Since our plastic septic tanks are made out of polyethylene, they are unaffected by soil chemicals and by the chemicals and gases present in sewage, so our plastic septic tanks will not rust or corrode.
Who makes plastic septic tanks?
The world’s leading manufacturer of polyethylene tanks, Norwesco has been producing polyethylene septic tanks since 1980.

How can you tell if a septic tank collapse?
Here are the signs your septic system’s got an issue and it’s time to call in the pros.
- Water (or sewage) is backing up inside your home.
- Green, spongy grass around your septic tank.
- You’ve got trees or shrubs near your system.
- Water’s pooling in your yard.
- A rotten egg smell.
- Slow drains.
Can heavy rain cause septic backup?
It is common to have a septic back up after or even during a heavy rain. Significant rainfall can quickly flood the ground around the soil absorption area (drainfield) leaving it saturated, making it impossible for water to flow out of your septic system.
Plastic vs. Concrete Septic Tanks
It is one of the most crucial components of the complete plumbing system that your septic tank is installed in. Septic tanks are designed to securely handle and treat all of the waste water that you generate. If your septic tank ceases to function, you must have it fixed or replaced as soon as possible. Septic system failures can cause extensive damage to your home’s plumbing system, as well as to your yard and property. They can even put you in danger! Unfortunately, septic tanks are not built to last a lifetime.
The installation of a new septic tank is a major undertaking.
Making the selection on what material to use for your new septic tank will be one of your most significant considerations.
Here are the advantages and disadvantages of each.
Plastic Septic Tanks
- Plastic septic tanks are less expensive to purchase and install than concrete septic tanks
- They are also more environmentally friendly. Easy to carry: Because plastic is significantly lighter than concrete, plastic septic tanks are less difficult to transport to your residence
- Installation is less difficult: In contrast to concrete septic tanks, installing plastic septic tanks does not necessitate the use of heavy machinery. Also available are plastic septic tanks, which may be installed in a wider range of settings. Inhibition of corrosion by water: Plastic septic tanks are entirely impervious to water-based corrosion. Exceptionally fracture resistant: Because plastic is more flexible than concrete, plastic septic tanks do not crack nearly as frequently as concrete tanks.
Cons
- Plastic tanks are not nearly as durable as concrete tanks and are therefore crushable. It is possible that they will be crushed under the weight of the dirt. Plastic tanks have been known to burst when vehicles drive over the regions where they were buried in the ground. Plastic tanks are sensitive to the environment and may burst or rupture as a result of changes in soil conditions or vibrations in the vicinity. Concrete tanks, on the other hand, are far less vulnerable to environmental degradation. Damage is a possibility because: Plastic septic tanks are more prone to breaking or warping than concrete septic tanks for a variety of reasons, including: Plastic tanks may require significantly more care than their concrete equivalents
- However, this is not always the case. Concretized septic tanks tend to have a longer lifespan than their nonconcrete counterparts, however this is not always the case.
Concrete Septic Tanks
- Concrete septic tanks are far more robust than their plastic equivalents
- They are also less expensive. Exceptionally long-lasting: Concrete tanks can survive for hundreds of years. An untreated concrete septic tank can live for up to 40 years if it is properly maintained and regularly drained. Concrete septic tanks are often not influenced by changes in their surrounding environment, such as shifting soil conditions, the growth of tree roots, or any other difficulties that may arise. Driving over the soil where a concrete tank has been buried will have no effect on it
- Yet, Septic tanks made of concrete are less prone to failure than those made of plastic since they are more durable.
Cons
- Expenses that are higher: Construction of concrete septic tanks is more expensive than the installation of plastic septic tanks. Installation is more challenging in the following cases: Due to the fact that concrete is heavier and more unwieldy than plastic, installation will take longer and will necessitate the use of heavy equipment. Because concrete tanks are not as resistant to corrosion as plastic tanks, they may ultimately corrode or break as the tanks age. This is more likely to occur if they are not adequately maintained. When it comes to repair, the following is more disruptive: If your concrete septic tank is broken, it might be difficult to repair it effectively, especially when compared to plastic tanks.
The following options are available when it comes time to select a new septic tank: Both types of tanks have their advantages, so the decision comes down to which one you believe would work best for your house and budget. Concrete tanks are more robust, but they are also more expensive, whilst plastic tanks are less expensive, but they are also more delicate.

Plastic Vs. Concrete Septic Tank
Plastic and concrete septic tank alternatives are available whether you’re installing a new septic tank or replacing an existing one, and you’ve probably seen them before. For the most part, homeowners are not overjoyed at the notion of shelling out a significant sum of money for something that essentially does nothing but handle wastewater. Although this is a significant commitment, it is not one that should be taken carelessly. They both have advantages and disadvantages, and we hope that this list will assist you in making a more informed selection.
Plastic Septic Tanks
Increasingly popular as an alternative to concrete septic tanks are plastic septic tanks. Typically, they are pre-fabricated and have an oblong oval form with ridges running around the exterior walls. They are readily available at most home improvement stores and are ready to be installed as soon as they are delivered to your residence.
Pros
They are rather light in weight due to the fact that they are composed of plastic. They typically weigh a couple hundred pounds and can be handled with relative ease by a standard pickup truck.
This means that not only is installation simpler, but it also means that all of the expenditures involved with it are reduced. Simply digging a hole, positioning the tank, and connecting the tank to the rest of your system is all that is necessary.
Plastic septic tanks are a more affordable option to concrete septic tanks due to the fact that they are lighter and easier to install. Saving money on installation costs is generally the most significant benefit, but you may also save money on the tank itself.
Cons
Plastic septic tanks are a more affordable option to concrete septic tanks since they are lighter and easier to install. Saving money on installation costs is typically the most significant benefit, but you may also save money on the tank itself. In order to function correctly, septic tanks must have an adequate balance of sludge (solids), effluent (water), and scum (lightweight solids) in their contents. Plastic septic tanks are lighter than concrete septic tanks, however they are incapable of holding as much effluent as a concrete tank.
Aside from the fact that they are less capable of handling significant quantities of wastewater, plastic septic tanks require more upkeep than concrete septic tanks.
When evaluating the entire cost of any system, it is critical to take this into consideration as well.
Concrete Septic Tanks
Concrete septic tanks are a more conventional alternative. You can select between having a pre-cast concrete septic tank supplied to your property or have a tank put in site. As soon as the prepared option is delivered, it is ready to be implemented immediately. In order to use the poured in place method, you must first dig the hole and then create a mold to shape your tank.
Pros
Concrete sewage tanks, in contrast to plastic septic tanks, are extremely long-lasting. Typically, they may be driven over without causing any damage. However, this is not true for your plumbing lines that run to or from the tank, therefore you must use caution when driving in this area of the city. Because concrete septic tanks are massive, they are capable of handling large volumes of sewage without experiencing any issues. This implies that they require less care and cleaning than plastic and can last longer between cleanings.
Cons
One of the most significant disadvantages of a concrete septic tank is the weight of the tank. They can weigh several tons, depending on the size of the house you need to build. With this amount of weight, it is evident that large machinery is required for transportation and installation, increasing the entire cost. Concrete septic tanks are less prone to be damaged, especially by environmental causes such as soil vibrations or root penetration. They are, on the other hand, more difficult to repair than plastic tanks if they are damaged or broken.
There are a variety of criteria that go into selecting which system is the greatest fit for you. We’re pleased to explore the many possibilities, the advantages and downsides, and what they imply for you. Posts from the recent past
Poly Septic Tanks vs Concrete: What They Don’t Tell You About Concrete Septic Tanks
The 6th of June, 2019 Septic Systems, CommercialOn-site septic systems are extremely crucial for both your business and your home’s health. When deciding on a polyethylene or concrete tank, it’s important to have a fundamental understanding of both, as well as their pros and downsides. This will help you pick the tank that best suits your needs while also saving you money on installation costs. First and foremost, as previously said, there are two prominent types of materials that are employed in the construction of septic tanks.
Concrete is the stronger of the two materials.
Septic Tank: Concrete vs Plastic
Despite the fact that concrete septic tanks are known to persist for a long time, they have a number of flaws, particularly when maintenance is neglected over time. If the quality is poor, they may even break during the manufacturing process. Advantages of a Concrete Septic Tank
Are said to be long-lasting with proper maintenance.
Disadvantages of Using a Concrete Septic Tank
As mentioned earlier, concrete septic tanks are heavy. Because of their heavy weight, they require different types of heavy equipment during installation, leading to more expense.
Poly septic tanks provide a number of advantages that exceed any potential disadvantages. Disadvantages of a Poly Septic Tank The fact that plastic septic tanks are lightweight and have the potential to “float” when water tables rise is perhaps the most significant reason why many object to their use (e.g. during extremely heavy rainfall). However, there are ways to avoid this from happening in the first place. The 2,200-litre poly septic tank built by Coerco. Advantages of a Poly Septic Tank
Poly septic tanks are watertight despite their lightweight quality.
It is undeniable that both concrete and polyethylene septic tanks require regular maintenance. When it comes to determining which type to choose, though, you might want to think about the long term implications of your decision. What modifications will be done to your property at that point? What about the costs of upkeep, removal, and relocation, for example? Septic tanks made of polyethylene are unquestionably the most reliable option if you’re looking for something that’s simple to maintain, install, and transfer while also being extremely reliable.
Wouldn’t you contact a firm that is competent, well-organized, and inventive and that can meet all of your commercial and household demands if you discovered such a company?
How much does a septic tank weigh?
And what is the significance of weight? Polyethylene septic tanks weigh approximately 200 kilograms, whereas their concrete counterparts weigh approximately 1,500 kilograms, according to the manufacturer. The ramifications of having large septic tanks For many years, concrete has been the material of choice for septic tank construction. Concrete, on the other hand, is a fairly heavy substance. When it comes to establishing a septic system, this results in increased prices. Working with concrete septic tanks entails a number of expenses, the first of which is the purchase of a larger truck and a crane.
- The ordinary poly septic tank, on the other hand, weights far less than the conventional cover for a concrete tank.
- Is it possible to relocate a septic tank?
- Given the weight and difficulty of moving some types of septic tanks – such as concrete – some people find it far easier to just purchase a new septic system rather than attempting to relocate a used septic system.
- Notably, because of its weight and vulnerability to collapse, concrete septic tanks are a potential source of hazard for homeowners.

Plastic vs Concrete Septic Tanks. Which Should You Get?
We just purchased a property with an older septic tank, which prompted me to do some research on different types of septic tanks. It was not something I had anticipated spending time on. It was cracked and was to be replaced by the vendor. The old concrete tank had been replaced with a new plastic tank, which I was astonished to discover after it had been replaced and we had moved into the house. I’d always assumed they were all made of concrete until now. That prompted me to inquire: are concrete septic tanks preferable to plastic septic tanks?
- However, to break it down fast, concrete septic tanks are excellent for their durability and long life.
- Because I am very much a septic tank rookie (if there is such a thing), I wanted to learn everything I could about how to properly manage our system before we installed it.
- I’d also like to know if our plastic tank is durable and will survive for several years, or if it will need to be replaced sooner rather than later.
- Seeing as how I know that I’m not the only one who has concerns about septic tanks, I decided to put all of my results in one place to make it simpler for you to get the answers you’re looking for, as well.
- As a result, I’ve included some information on pricing as well.
- You should expect to pay additional costs for labor and other materials if you are having your septic system repaired, replaced, or installed entirely from scratch.
- A concrete or steel tank, if you have an older tank on your property, is most likely the material used.
The longer they remain in the ground, the more deterioration they experience.
Why?
Is it possible to see your youngster running around in the yard and falling into it?!) Septic tank made of old, rotted steel Concrete, fiberglass, or plastic are the most common materials used in contemporary tanks on residential properties.
Here’s what I’ve learnt thus far.
Tanks made of plastic are typically oblong in shape with a lot of ribs on the sides and bottom.
It also aids in their ability to tolerate external pressure such as that exerted by the soil and water.
This is significant because a smooth-sided tank in the ground may be more susceptible to slipping out under certain conditions, such as super-saturated soil from heavy rains, among other things.
The weight of a 1000-gallon polyethylene tank is little more than 300 pounds.
As a result, the cost of having a considerably larger tank delivered would be avoided, as would the usage of the heavy machinery required to lift and install the tank into place in the earth In other cases, such as when putting the tank in a difficult-to-reach area with a huge truck, the ability to transport it in the back of your pickup truck may be the decisive factor in whether or not to use plastic.
- The fact that they do have some inherent flex makes them less susceptible to cracking as a result of ground freezing, which is another advantage of using plastic tanks.
- It is more environmentally friendly.
- Naturally, this will cause harm to the system and lead you to be unable to use it until the problem is resolved.
- Aside from that, even though they are severely ribbed to make them stronger than a smooth-sided tank, they can become warped as a result of the forces of the earth surrounding them.
- The average lifespan of a plastic septic tank should be 30 to 40 years, assuming that it is properly cared for and maintained.
Price per gallon: Of course, prices vary depending on where you live, but it appears that plastic septic tanks cost about $1 per gallon — or about $1,000 for a 1,000-gallon tank and about $1,500 for a 1,500-gallon tank — with a $1,000 tank costing about $1,000 and a 1,500-gallon tank costing about $1,500.
- However, I believe that fiberglass outperforms plastic on at least one aspect.
- External influences should not have an impact on them.
- There aren’t any downsides in this case.
- The life expectancy of this product is similar to that of plastic tanks.
- In addition, the cost is around $1 per gallon, or approximately $1,000 for a 1,000-gallon tank and approximately $1,500 for a 1,500-gallon tank.
- They can either be constructed on-site or pre-cast.
- The concrete is then poured into the mold, where it is allowed to set and cure while still in the mold.
A different place makes them, and they are delivered to your location for installation.
Pre-cast firms create molds for concrete tanks and other concrete objects, pour the concrete into the molds, and then store the concrete tanks and other concrete items on site until they are transported to the building site.
Concrete will not corrode, rust, or dissolve under normal conditions.
Additionally, the strength of concrete septic tanks will outperform that of plastic or fiberglass septic tanks.
The huge weight of a concrete tank is a possible disadvantage, which you can read about further below, but it is also a good element since the incredible weight means that they are significantly less likely to shift in the ground as they are being built or installed.
First and foremost, they have the potential to break or split, enabling sewage to spill out (although this is unlikely to occur for many years).
The seller was previously aware that it had cracked at one of the top corners and that he would not be permitted to sell the house until it was replaced.
A concrete septic tank with a capacity of 1,000 gallons weighs approximately 8,000 pounds (or 4 tons).
Longevity: If properly cared for, they should easily endure for 40 years or more.
Cost on average: A concrete septic tank is often less expensive than a plastic or fiberglass septic tank, according to what I’ve learned about the industry.
Septic Tanks Made of Steel Currently, I have not discovered any stores that sell steel sewage treatment tanks, but these appear to be very old-fashioned in appearance.
However, the potential drawbacks are significant.
Consider all of the times you have come across a metal can that has been buried in the ground for a long period of time, or that has just been exposed to the weather for a long period of time.
Tanks made of steel not only put people’s lives in danger by allowing sewage to seep into the ground, but a rusted steel lid may easily collapse when someone walks over it, throwing the person into the tank!
This is something to bear in mind if you are acquiring or owning a home that already has a steel tank installed, even if buying a steel tank is almost always out of the question.
What is the best type of septic tank to use?
If you intend to remain in your home for an extended period of time and if large trucks can easily reach your location, I believe it is worthwhile to spend the extra money to have a concrete septic tank installed for the added peace of mind it provides.
Finally, plastic tanks are the most cost-effective and convenient option for those looking for the lowest possible price and the quickest possible delivery. Now that you have a new septic tank on the way, here are some pointers on how to keep it in good working order.
Plastic vs Concrete Septic Tanks
Even though it is not something I had anticipated doing, we recently purchased a house that had an older septic tank, and I have been researching different types of them. It had a fracture in it, and the vendor was going to replace it. I was surprised to discover that the old concrete tank had been replaced with a new plastic tank after it had been replaced and we had moved in. Every one of them, I had always assumed, was made of concrete. I was then prompted to ask the question: are concrete septic tanks preferable to plastic septic tanks?
- However, to summarize, concrete septic tanks are durable and long-lasting, making them a good choice for many situations.
- Because I am a complete septic tank novice (if there is such a thing), I wanted to learn everything I could about how to properly maintain our system.
- In a nutshell, have we been saddled with a short-term solution that will only cause us problems in five years?
- You may be in the market for a new or replacement septic tank, so I’m assuming you’re researching the various types of septic tanks for your home construction project.
- NOTE: The costs I discovered are very general and only apply to the tank.
- How Many Different Types of Septic Tanks Do You Need to Install?
- As a result, if you have an older steel septic tank, you should consider replacing it immediately.
As a result, they can create a huge mess when they are removed, and they can also pose a serious threat to anyone who crosses them.
This is due to the fact that the steel lids deteriorate at a faster rate than the tank.
Your tank is either made of concrete, fiberglass, or plastic if it is a newer addition to your property.
Listed below are some of the things I’ve discovered: Septic Tanks Made of Plastic.
A typical plastic tank’s shape is oblong with heavy ribs on the sides and bottom.
They can also withstand external pressure from the soil and water that is pushing in on them as a result of this.
Even so, it’s possible that it will happen.
Just a little more than 300 pounds is the weight of a 1000-gallon polyethylene storage tank.
As a result, the cost of having a much heavier tank delivered would be avoided, as would the cost of the heavy equipment required to lift and set the tank into place.
Due to their inherent flexibility, plastic tanks also have the advantage of being less susceptible to cracking as a result of ground freezing.
For those who live in a very wet climate, the tank may shift or even rise as a result of the moisture in the ground.
In addition to being inconvenient, this may prove to be costly.
The tank cannot be placed in a location where it could be run over by a vehicle, as a result.
In comparison, the average person only stays in their home for a few years before deciding to move.
Septic tanks made of fiberglass Aside from the difference in price and longevity, fiberglass and plastic septic tanks are very similar.
As a result of the fact that fiberglass does not bend, these septic tanks are more structurally sound than plastic tanks.
Considering the size of the tank, it weighs approximately 300-350 pounds for a standard-sized tank.
If you were hoping to get fiberglass tanks at one of the large box home improvement retailers, you may be disappointed.
When properly maintained, fiberglass septic tanks have a lifespan of 30 to 40 years.
Septic tanks made of concrete Septic Tanks Made of Precast Concrete The use of concrete septic tanks is very common in both older homes and newer construction.
During on-site construction, a hole is dug in your yard and a form (similar to a mold) is constructed inside the hole.
A pre-cast septic tank is another option.
Concrete barriers used as motorway dividers during construction, as well as sewer pipes and bridge parts, were all manufactured somewhere else than the actual site where they were to be utilized.
A few significant advantages of concrete over plastic or fiberglass septic tanks are that they are stronger and may survive for a significantly longer period of time.
It will endure eternally as long as it does not break or split (see Cons section below).
The internal and external forces are better absorbed by them than by alternatives The huge weight of a concrete tank is a possible disadvantage, which you can read about further below, but it is also a good element since the incredible weight means that they are significantly less likely to shift in the ground when they are being built or repaired.
- As a result, when we purchased the tank at our house, the situation was as follows: The seller was already aware that it was cracked along one of the upper corners and that he would not be permitted to sell the house unless it was repaired.
- A concrete septic tank with a capacity of 1,000 gallons weighs approximately 8,000 lb (or 4 tons).
- Longevity: If properly cared for, they should easily last for 40 years or longer.
- Cost on an annual basis: $1,500 A concrete septic tank is generally less expensive than a plastic or fiberglass septic tank, according to what I’ve learned about them.
- Septic tanks made of steel Currently, I have not discovered any stores that sell steel sewage tanks, but these appear to be very old-fashioned in appearance.
- However, there are significant risks involved.
- Assume you have come across a metal can that has been buried for an extended period of time, or that has simply been exposed to the elements for a significant amount of time.
Tanks made of steel not only put people’s lives in danger by allowing sewage to seep into the ground, but a corroded steel lid can easily collapse when someone walks over it, throwing them into the tank!
This is something to keep in mind if you are purchasing or owning a home that already has a steel tank installed, even though buying a steel tank is almost always out of the question in this situation.
Which Septic Tank is the Most Appropriate for Your Needs.
It is worth the extra money to have a concrete septic tank installed if you intend to stay in your home for the long haul and if large trucks can easily access your location.
Fiberglass tanks appear to be the most cost-effective option if price is a consideration, or if large trucks will have difficulty getting to your location due to road conditions.
After all is said and done, plastic tanks are the most cost-effective and convenient option when it comes to getting the tank yourself. Now that you’ve decided to install a new septic tank, here are some pointers on how to properly maintain it.
Plastic Septic Tanks
Some of the numerous advantages of adopting a plastic rather than a concrete septic tank are as follows:
- Unlike concrete sewage tanks, plastic septic tanks are extremely resistant to breaking. Rusting isn’t a problem at all. Because plastic weighs far less than concrete, it is much easier to transport a plastic septic tank to its final installation position. It is more cost-effective to use a plastic septic tank rather than a concrete septic tank. Plastic septic tanks have the potential to be watertight and corrosion resistant.
However, there are some advantages to utilizing a plastic septic tank rather than a concrete septic tank. Some of these advantages include, but are not limited to, the following:
- Plastic septic tanks have lower effluent levels than concrete septic tanks, which may be noticed when a tank is opened for pumping. If not placed properly, a plastic septic tank has the potential to “float” to the surface of the earth
- However, this is rare. Because plastic is such a lightweight material, it is susceptible to damage during the installation process. In certain states, plastic septic tanks are not permitted to be used. (You may find resources for your state by clicking here.)
When is it permissible to use a plastic septic tank? When plastic septic tanks are legal in your state and when cost is a big concern, they may be the best option. At the end of the day, you must choose whether a plastic septic tank is the best option for your project.
Concrete Septic Tanks
The advantages are as follows:
- Compared to plastic septic tanks, concrete septic tanks produce greater quantities of effluent. Because concrete septic tanks are hefty, they have little likelihood of floatation, in contrast to plastic septic tanks, which do. Concrete septic tanks are exceptionally long-lasting and resilient
- They can survive for decades. There are no restrictions on the use of these septic tanks in any state.
The Disadvantages are as follows:
- Septic tanks made of concrete are quite pricey. These septic tanks are susceptible to cracking under harsh conditions. The installation of concrete is quite tough due to the weight of the material. Despite the fact that concrete septic tanks are quite resilient, they are more prone to cracking and leaking.
When is the use of a concrete septic tank recommended? Concrete septic tanks are ideal in situations where concrete is required by zoning rules. Additionally, concrete is preferred by septic specialists when the value of the product is more essential than the cost.

- Selecting a septic tank
Septic tanks are a vital part of your property’s infrastructure, and it’s crucial to understand the pros and cons of the many materials that may be used before choosing on a particular type of septic tank to use. Concrete and plastic are the most often used materials for septic tanks, each of which has its own set of problems. Plastic septic tanks are built of a durable plastic that is significantly lighter and more cost-effective than concrete septic tanks. They are also more environmentally friendly.
- Plastic septic tanks, according to the Pink Plumber, are also fully impervious to water-based corrosion, and because plastic is more flexible than concrete, it is more resistant to some types of damage.
- The weight of heavy soil or the weight of vehicles driving over the tank might cause the tank to break.
- They have a lower effluent level and, if the water table is high, they may “float,” rising above the depth at which they were designed to operate.
- Finally, in certain states, the usage of plastic septic tanks is not permitted.
- Concrete tanks are more sturdy and resistant to environmental deterioration than plastic tanks, and as a result, they require less maintenance than plastic tanks on average.
- Concrete tanks are fully impervious to “floating,” and Septic Tank Pro says that concrete tanks have a greater effluent level than other types of tanks because of their weight.
- Concrete tanks, on the other hand, are significantly more costly, owing in large part to their weight.
- Installation necessitates the use of heavy equipment, and concrete tanks are often more disruptive to the environment during both the installation and maintenance processes.
- Concrete is frequently chosen as the default material since it is legal in every state, has been the preferred building material for a long time, and is more resistant to damage caused by weight or shifting than other options.
- Plastic tanks are far less expensive than concrete tanks, which can cost several thousand dollars or more.
- Septic tanks made of concrete can be damaged by high levels of acidic groundwater, hence plastic is the preferred material in these circumstances.
Despite the fact that there are several aspects to consider, both concrete and plastic septic tanks are excellent solutions. Take into consideration your current position as well as your geographic area, and then choose the one that feels most right.
Plastic Septic Tanks
Plastic septic tanks are lightweight and easy to transport. It is the most suitable septic tank for usage in an emergency situation or as a portable tank. Because it weighs less than concrete tanks, plastic septic tanks manufacturers have an advantage when it comes to transporting and installing them. When it comes to people on a tight budget, the costs of plastic septic tanks will almost certainly convince you to get one because they are far less expensive than other types of tanks such as concrete or fiberglass.
In our capacity as septic tank providers, we planned to develop this tank for both commercial and residential applications.

Concrete vs Plastic Septic Tanks – A Clean Comparison
You don’t like to think about it, but your home’s septic tank is responsible for a great deal of damage. It is used to collect, store, and treat all of the waste water generated by your household. If your septic tank breaks down or malfunctions, it must be fixed or replaced as soon as possible. And what happens if you don’t do anything? It has the potential to harm your plumbing system and possibly leak into the structure of your home. It’s possible that you’ll be looking at thousands of dollars in losses.
When purchasing a septic tank, you will have to decide between two different types: concrete septic tanks and plastic septic tanks.
Ready?
Now, without further ado, let us look at the differences and similarities between the two types of tanks.
Concrete vs Plastic Septic Tanks
Sometimes the most effective method to assess two solutions is to simply go over their advantages and disadvantages. After that, I’ll go into greater detail on how to choose between the two options.
Concrete Septic Tank Pros
Concrete septic tanks provide a number of advantages over other types of tanks, including the fact that they are significantly more robust and hefty. These characteristics make them long-lasting and suited for use in a variety of weather and climate settings. Because they’re hefty, they have a good chance of settling into the soil and not drifting about or floating. Because they are buried in the earth, they are also better able to endure external pressure. Despite the fact that they require little maintenance, concrete septic tanks may endure for up to 40 years.
In addition, it requires extremely minimal upkeep and maintenance.
Last but not least, these tanks have been independently tested and found to be safe for use in the United States.
Concrete Sepic Tank Cons
It is important to note that concrete septic tanks are far more robust and hefty than other types of sewage holding tanks. These characteristics make them long-lasting and suited for use in all kinds of weather and climatic situations. As a result of their weight, they are well-anchored in the ground and do not move or float. Because they are buried in the earth, they are better able to endure external pressure. Despite the fact that they require little maintenance, concrete septic tanks can endure for 40 years or more.
Aside from that, it takes little upkeep as well. It is neither harmed or influenced by soil conditions or tree roots in the least. In addition, these tanks have been approved for usage in the United States of America.
Plastic Septic Tank Pros
One of the most significant advantages of plastic septic tanks is that they are far less expensive than those constructed of concrete or other materials. As a result, they are a cost-effective purchase, especially if they must be updated every few years. Plastic septic tanks are less expensive and easier to transport and install than concrete septic tanks. This is due to the fact that plastic is very lightweight, making these septic tanks easier to carry and install. This reduces the amount of money spent on installation.
Because plastic septic tanks are also fairly sturdy and flexible, they do not break as quickly as concrete septic tanks do.
Plastic Septik Tank Cons
One significant disadvantage of placing a plastic septic tank in your home is that it is susceptible to being crushed by the weight of the earth surrounding it. Alternatively, it might be caused by the pressure of people and cars passing over it. It can also be harmed as a result of the soil conditions or vibrations in the ground below ground. This is why modern septic tanks do not have a much longer lifespan than concrete tanks. They also require more care, which is why it’s best to replace them as soon as a problem arises rather than waiting.
This has the potential to cause damage to the plumbing system.
How to Choose Between these Two Septic Tanks?
The question is, how do you choose between concrete and plastic specialized tanks? I’ll make it simple for you by stating the most important considerations you should take into account.
Cost
When deciding between the two tank types, one of the most important considerations is the cost. A concrete septic tank is significantly more expensive than a plastic one. Furthermore, its installation is more expensive. The concrete tank, on the other hand, may survive for 20-30 years, which would explain its high cost. A plastic one, on the other hand, may not last more than 3-5 years before needing to be replaced, requiring you to change it every few years. So try them all out and see which one you like.
Size
Remember to measure the dimensions of your old septic tank before purchasing a new one to ensure that they are the same size as before. This will allow you to complete the installation process much more quickly and efficiently. If, on the other hand, you’re working on a new building project, make sure to have your contractor measure the space and advise you on the appropriate size to use. In an ideal situation, the size of a septic tank is decided by the amount of water that a family uses on a daily basis.
900-gallon water storage tank is sufficient if you use less than 500 gallons of water each day. This is taking into consideration the fact that it will have to treat wastewater, which is far heavier than regular water.
Design
In addition to size and placement of your septic tank, the design of your system is critical. For example, when your tank will be buried inside gravel or coarse soil, you can employ a pressure-type septic system to ensure proper drainage. It is possible to get by with a gravity system in the presence of rich soil. Make sure you understand the sort of soil you are working with beforehand.
Pumps
There are several various types of pumps that may be installed in a septic tank, no matter how large or little it is. The turbine pump is the most frequent of them, and it has a longer lifespan than the others. You can also utilize a centrifugal pump, which is less durable but more cost-effective than a reciprocating pump.
Durability
With regard to strength and durability, concrete septic tanks can resist far more damage or fracture than plastic septic tanks. Despite the fact that the latter are more flexible, they are more susceptible to damage than the concrete ones. Because of their weight, they also maintain a firm grip on the ground.
How Do I Know My Septic Tank Needs Replacement?
With regard to long-term durability, concrete septic tanks can endure far more damage or fracture than plastic septic tanks do. Despite the fact that they are more flexible than concrete, they are more susceptible to damage. Because of their weight, they also maintain a stable position.
- You discover that wastewater is being pumped back into the residential drain system. You observe brightgreen and spongy grass on the drain field, despite the fact that there has been no rainfall or moisture
- The water level surrounding your septic tank or in your basement has risen significantly
If you see any of these indicators, it’s likely that it’s time to replace your sewage treatment system.
How Do Septic Tanks Work?
Homes that do not have access to the municipal water supply are required to have septic tanks installed. As part of the construction of such homes, the sewage pipes are connected to the septic tank, which is located underground. It receives all of the wastewater from the house, which is flushed into it. It can retain a large amount of water for an extended period of time, allowing solids to settle at the bottom and oily residue to float at the top. Once the liquid wastewater has been drained into the drainfield, which is a dug-out area in unsaturated soil, it is disposed of properly.
The soil holds the waste while allowing the water to pass through, which eventually mixes with the groundwater supply.
Conclusion
In this way, you can see that understanding which elements are more important to you when making the decision to purchase a concrete or plastic septic tank is essential. At the end of the day, a well operating septic tank that has been properly maintained will perform admirably. All you have to do now is figure out which one is the most appropriate for you. And I hope that this post has assisted you in distinguishing the differences between concrete and plastic septic tank. And which one would be a better fit for your particular situation.
Thank you for taking the time to read this, and have a wonderful day!
