Fiberglass tanks are watertight and are resistant to corrosion. Also, they’re lighter than concrete septic tanks. On the contrary, concrete tanks are heavy and are prone to corrosion. According to a study, lightweight septic tanks are more vulnerable to damage during installation when compared to concrete septic tanks.
- Longer Life Span – fiberglass septic tank are unaffected by the gases created by sewage so they won’t deteriorate like concrete or steel tanks. Easier to Repair – In the unlikely event of damage, fiberglass septic tanks can be repaired much more easily than concrete or steel septic tanks.
Which is better concrete or fiberglass septic tank?
While concrete is known for its durability, fiberglass septic tanks are even more durable. Once buried, fiberglass tanks become completely inert. Unlike concrete, it won’t degrade, rust, or weaken. Fiberglass septic tanks also require less maintenance than concrete septic tanks do.
How long does a Fibreglass septic tank last?
Steel septic tanks have a life expectancy of 15 to 20 years. These should not be used for new installations but can still sometimes be found in older rural properties. Plastic (PE) or fiberglass tanks (GRP) have a life expectancy of 20 to 30 years.
What material is best for a septic tank?
The best choice is a precast concrete septic tank. Precast septic tanks hold many advantages over plastic, steel, or fiberglass tanks. This is why so many cities and towns actually require the use of concrete septic tanks.
Which septic tank is better concrete or plastic?
Cement Septic tanks are very durable than plastic tanks and, if kept properly, can have extended longevity. With regular draining and proper maintenance, a cement septic tank can last for up to 40 years. Cement septic tanks are resistant to environmental changes such as tree roots or changing soil conditions.
What is the cheapest septic tank?
Types of Septic Tank Systems These conventional septic systems are usually the most affordable, with an average cost of around $3,000.
Are fiberglass septic tanks any good?
If you’re planning to install a new septic tank or replace an existing one, then a fiberglass tank can be a great choice! 1. They weigh less compared to steel and concrete tanks and can be easily installed anywhere. This can be a huge advantage in areas where big trucks or cranes find it difficult to reach.
Does heavy rain affect septic tank?
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.
What can I use instead of a septic tank?
Alternative Septic Systems
- Raised Bed (Mound) Septic Tank Systems. A raised bed drain field (sometimes called a mound) is just like what it sounds.
- Aerobic Treatment Systems (ATS) Aerobic systems are basically a small scale sewage treatment system.
- Waterless Systems.
How often should a 1000 gallon septic tank be cleaned?
For example, a 1,000 gallon septic tank, which is used by two people, should be pumped every 5.9 years. If there are eight people using a 1,000-gallon septic tank, it should be pumped every year.
What is the most expensive septic system?
A mound septic system costs $10,000 to $20,000 to install. It’s the most expensive system to install but often necessary in areas with high water tables, shallow soil depth or shallow bedrock.
Do plastic septic tanks collapse?
Guide to Plastic or Fiberglass Septic Tanks Fiberglass or Plastic Septic Tanks: are very resistant to some of the problems occurring with concrete (cracks) or steel (rust) septic or home made (collapse) septic tanks.
Can you patch a fiberglass septic tank?
Yes, most definitely! Fiberglass has a long history of being repaired. Small holes in fiberglass can be repaired as well as large cracks. Even if a fiberglass septic tank is split completely in half it is repairable.
How long will a plastic septic tank last?
A septic tank can last between 20 and 40 years. The lifespan depends on the tank’s material. A steel tank lasts 20 years, while a concrete tank lasts 40 years. Plastic tanks can last as long as 30 years.
A Short Guide on Fiberglass Septic Tanks (Updated for 2020)
A septic tank is an underground chamber into which wastewater is channeled for basic treatment before being discharged. Typically, these tanks are used to store effluent from household sources, but they are now now being used in businesses and factories to store wastewater that has comparable qualities to that of domestic effluent. Septic tanks are designed such that the liquid flows through the tank while the heavier particles fall to the bottom of the tank. The scum (which is mostly comprised of oil and grease) floats to the surface.
Septic tanks are generally classified into four categories, which are available on the market: Septic tanks made of fiberglass septic tanks made of steel Septic tanks that use aerobic bacteria Septic tanks made of concrete In this blog post, we’ve offered a brief overview of fiberglass tanks and how they work.
What is Fiberglass Septic Tank?
Tanks built of fiberglass, as the name implies, are constructed of fiber or a sort of modified plastic. They are lighter in weight than the other kinds and are resistant to corrosion and breaking when compared to the others. The nicest aspect about these tanks is that they are quite simple to put together. However, there are a few things that you should keep an eye out for while evaluating one: Check for a faulty plastic stopper at the bottom of the tank after you have emptied it to see whether the level of the effluent has dropped too low.
- Observe for signs of abnormally low effluent levels as well as the absence of drain plugs.
- A gravel-filled tank is used for this test, and water is pumped into the tank to stimulate groundwater pressures as part of it.
- The greater the number, the better!
Fiberglass Septic Tank Cost
The cost of a fiberglass septic tank primarily depends on the size of the tank and quality of the material used to build it. In the United States, the average price lies somewhere between $1600 – $2000. Depending on the construction methods, the condition of the soil, and the materials used while manufacturing, a fiberglass tank can last as long as twenty to thirty years.
How Does a Fiberglass Septic Tank Work?
Essentially, a septic tank is an underwater sedimentation tank that is used to cleanse wastewater through a process of biological breakdown and drainage. The design of fiberglass tanks is straightforward. It consists of a fiberglass container (often rectangular or spherical in shape) buried underground and sealed against the elements. The tank is connected to the rest of the system by two pipes: an input and an output. It is the input pipe’s responsibility to collect wastewater in the septic tank, whereas it is the outlet pipe’s responsibility to remove the pre-processed wastewater from the septic tank and disperse it evenly across the soil and watercourses.
The top layer is primarily made up of oil and grease, which floats above the rest of the waste and collects water.
The wastewater and waste particles that make up the intermediate layer are collected here.
Bacteria from wastewater break down the solid waste that accumulates inside the tank. These bacteria also degrade solid waste fast, allowing liquids to separate and drain away more quickly as a result of the rapid decomposition.
Which is Better Concrete or Fiberglass Septic Tank?
Fiberglass tanks are waterproof and corrosion-resistant, making them ideal for storage. Additionally, they are less heavy than concrete septic tanks. Rather than being lightweight and resistant to corrosion, concrete tanks are hefty and susceptible to corrosion. When compared to concrete septic tanks, lightweight septic tanks are more susceptible to damage during the installation process, according to a recent research. Concrete septic tanks are also far more expensive to construct and maintain than fiberglass septic tanks, both in terms of installation and maintenance expenses.
Additionally, if fiberglass tanks are built incorrectly, they will frequently float on the ground’s surface.
The most problematic aspect of concrete septic tanks is that they frequently break when exposed to extremely hot or cold weather.
To summarize, fiberglass tanks are the most cost-effective alternative if you’re seeking for a tank that will meet your needs while still being affordable.
Advantage and Disadvantage of Fiberglass Septic Tanks
If you’re intending to construct a new septic tank or replace an old one, a fiberglass tank may be an excellent option for you. Here are some of the reasons why you should select it over the alternatives: 1.They are less in weight as compared to steel and concrete tanks, and they may be erected almost anyplace. Large trucks and cranes may be unable to access certain regions, which might be a significant benefit in some cases. 2.They are small enough to be transported in a pickup truck. 3.They are extremely strong and long-lasting.
- 4.They have a higher resistance to corrosive elements than concrete storage tanks.
- The roots of plants find it difficult to enter them, in contrast to the situation with concrete tanks.
- Let’s talk about it!
- Because these tanks weigh less than concrete tanks, you must take the necessary precautions to ensure that they are properly anchored to the ground before using them.
- A fiberglass tank that has been correctly constructed and secured can survive for many years without causing you any concern.
So there you have it, a quick overview of fiberglass septic tanks. Keep in mind to share your ideas in the comments area below! Also, please let us know if there is something crucial that we have overlooked.

Which Septic Tank Material Should You Use?
Receive articles, stories, and videos about septic tanks delivered directly to your email! Now is the time to sign up. Septic Tanks and More Receive Notifications Many different types of materials have been utilized to create septic tanks over the course of history. The following materials are most frequently used in the construction of septic tanks: 1. Resin made of polyethylene and polypropylene The use of fiberglass-reinforced plastic is another option. Precast concrete is a third option. Tanks made of precast concrete have traditionally been used for on-site water storage.
The use of tanks made of fiberglass reinforced plastic (FRP) and polyethylene is becoming more popular.
Tanks made of polyethylene/polypropylene “poly” can be rotationally molded in one piece or injection molded in two sections depending on the application. The bending and cracking of certain early poly tanks were a concern both during installation and while in use. Tanks with a ribbed or corrugated construction are more structurally sound than older models. Septic tanks’ structural soundness and watertightness are dependent on the use of high-quality raw materials and the careful attention paid to production procedures.
In the manufacturing of poly tanks, rubber and plastic pipe seals are frequently employed; in addition, access risers are often constructed of the same polymers as the tank itself to provide a seamless aesthetic appearance.
Most local codes have approved poly tanks, and manufacturers specify where and how poly tanks may be used; therefore, when evaluating the use of any tank in onsite systems, it is important to review the strength and other requirements included in the manufacturer’s installation instructions, as well as the manufacturer’s specifications.
- Installation is simplified by the fact that poly tanks are lighter than concrete, which is advantageous on difficult-to-access sites. No rust or corrosion, and they are resistant to the chemicals and gases found in sewage and soil, allowing them to last for a longer period of time than other materials. Contractors may deliver themselves, eliminating the need for a boom truck or the need to wait for delivery. The design minimizes the number of seams and joints that may leak
- Because of their low weight, steel tanks are more likely than concrete tanks to float out of the ground in locations with high water tables. Larger capacity are not normally offered
- Nonetheless, Typically only available in a limited number of different sizes
- Typically, there is no rating for traffic
- Have a restricted depth of burying (often 4 feet, but verify with the manufacturer for exact depth)
- Some brands must have water or wastewater in them at all times
- Others do not. In order to assure structural integrity, certain installation criteria must be followed.
Fiberglass Reinforced Plastic (FRP)
Some fiberglass tanks are built as a single piece. Others are manufactured in two pieces by the use of an injection molding technique. Structure soundness and watertightness are both dependent on the use of high-quality raw materials and the strict adherence to production standards, as previously indicated. FRP tanks may leak as a consequence of shipping damage, a faulty batch of glue, uneven application of adhesive, or tension imposed on the midseam during installation, however this is not typical.
The assembling procedure must be meticulously carried out to ensure that the joint does not leak or split.
While the glue is curing, the bolts are mostly employed to keep the pieces together while the adhesive cures.
Pipe penetrations and access riser joints, just like with tanks composed of other materials, must be carefully sealed to ensure that they do not leak and cause damage.
If joints are not watertight, the functioning of the tank is significantly diminished owing to the greater danger of water invading the tank. Testing for watertightness in the field is simple and may be accomplished by filling the tank with water (above the seams) and looking for any leaks.
- The tanks are less heavy than concrete tanks, which might be advantageous in difficult-to-reach locations. They are not susceptible to rust or corrosion, and they are resistant to the chemicals and gases found in sewage and soil. Larger capacity options are available. It is possible to build for a deeper burial and to have a traffic rating
- Because of their low weight, steel tanks are more likely than concrete tanks to float out of the ground in locations with high water tables. In order to assure structural integrity, certain installation criteria must be followed. When compared to concrete and polyethylene tanks, steel tanks might be less cost-effective. Typically only available in a limited number of different sizes
Precast septic tanks are normally made in two sections, with a seam either at the lid or in the middle of the tank’s body. Blended compounds, such as butyl rubber-based or asphalt-based (bituminous) sealants, are commonly used to seal precast tanks that are made of several pieces. It is possible for a leak to occur at the inlet and outlet pipe penetrations, particularly if the tank or piping settles or moves as a consequence of faulty bedding or installation. Mechanically sealing these connections to the tank is essential to ensure that they are both waterproof and flexible.
- Rubber boot seals are particularly attractive since they are flexible and maintain a seal even after backfilling and settling has taken place.
- Steel reinforcement is employed in accordance with the tank design to offer additional structural capacity during handling, installation, testing, and operation of the tank, among other things.
- The compartment walls are normally cast in one piece with the tank, similar to how the tank is constructed.
- When it comes to horizontal joints, preformed flexible joint sealants consisting of butyl rubber or asphalt-based compounds are utilized to seal them.
- These connections should be made with cast-in, waterproof, flexible resilient connectors that allow the tank and pipe to move freely without the chance of a leak forming between them.
- As with other tank materials, it is critical that the tank be waterproof, and in-field verification at the time of installation may be accomplished quickly and simply using proper techniques.
- Because of the density of concrete, it has a higher resistance to buoyancy. Installation criteria that are less strict
- The containers are available in a variety of sizes, including extremely large capacity. It is possible to build for a deeper burial and to have a traffic rating
- It’s less difficult to modify
- On sites with restricted access, the weight of the material and the equipment required for placement might be challenging. It is possible for corrosion to occur.

Fiberglass Septic Tanks
When comparing fiberglass septic tanks to plastic septic tanks, we, as a provider of fiberglass septic tanks, have our own observations. When it comes to fiberglass septic tank pricing, it is obvious that it is well worth the investment because fiberglass does not flex when compared to plastic. Even while the cost of fiberglass septic tanks is slightly greater than that of plastic septic tanks, it is well worth it in order to prevent the problem of bending or distortion, especially if the groundwater table is higher than the tank’s base, since groundwater pressures can be extremely high.
Fiberglass septic tank installation will be noticeable for its sturdiness and the fact that it will not deform.
Septic tanks made of fiberglass are commonly found in residential structures.
|SMC Septic Tank|
|0.5||700 x 1280||0.5||3.2||30|
|1||900 x 1640||1||4||50|
|1.5||1100 × 1600||1.5||4||55|
|2||1200 x 1900||2||4||84|
|2||1200 x 1900||2||7||120|
There are several different sizes of fiberglass septic tanks, ranging from 750 gallon to 10000 gallon. The 1000 gallon fiberglass septic tank is the most popular choice among consumers for domestic usage. Everything is dependent on how much is consumed. Septic tanks of greater capacity are required for commercial enterprises such as hotels, as well as public facilities such as hospitals and schools.
Fiberglass septic tanks are delivered in waterproof containers, preventing any groundwater from leaking in. It has a maximum burial depth of 4 feet and may be installed to that depth.
In certain circumstances, this is the time of year when other businesses opt to utilize concrete instead. Although the costs of a fiberglass septic tank and a concrete septic tank are different, the cost is important. In comparison to concrete, the lifespan of a fiberglass septic tank is noticeably shorter, but it is still fairly priced when taking into account the durability of the tank. It is the perfect time to purchase a fiberglass septic tank, especially during the period when they are on sale.
Fiberglass septic tank manufacturers put themselves in the shoes of their customers to understand their needs. This is why, after seeing failures of septic tanks built of other materials, this invention became a reality. Placing a fiberglass septic tank within a concrete inclusion will result in improved performance over the course of time. Because concrete is not waterproof, and fiberglass is an impermeable material composition, a complete waterproofing and resistance to deformation will be obtained using this material composition method.
Taking on fiberglass septic tank repair may be of less concern because this product is rarely proven to have any defects, even when used for an extended period of time. According to the manufacturer, fiberglass has the ability to withstand distortion and cracking, which are two undesirable effects that should be avoided. The principle of the FRP septic tank is followed. According to this theory, waste particle discharge mixed with liquid and sediment closed anaerobic fermentation, ammonification, liquefaction, biological antagonism and other processes such as mosquito breeding control are used to achieve the goal of excrement detoxification through the removal and disinfection of germs and bacteria as well as through the control of mosquito breeding.
Sediment Precipitation Area
On the domestic sedimentation, the most significant substance that sinks into the bottom sediment treatment of fiberglass septic tanks is sewage from the domestic sedimentation. It settles to the bottom of the water column while being over-layered with the water surface above it. A very active microbial population has been developed to destroy the complicated structure of refractory organic materials, allowing it to be dissolved more readily.
In order to enhance the retention duration of wastewater in a pool, the owner must ensure that the DC water is generated into a circulating water stream during the installation of a fiberglass septic tank. In this method, the sewage in the pool and sedimentation sludge will be in touch for a longer period of time, resulting in the production of more microorganisms, which will aid in the digestion of the sewage.
Filter Processing Area
We, the fiberglass septic tank makers, have created a tank that is distinct in both appearance and function since it incorporates innovative biofilm treatment technology that is now in use both domestically and internationally. After a time of culture, a large number of microorganisms reproduce on the surface of the filter, resulting in the formation of a biofilm contact. Microorganisms degrade organic stuff in sewage by preventing it from decomposing, adsorbing it, and decomposing it further.
- Area of sedimentation and precipitation Septic tank divider made of fiberglass Area for filter processing Extremely Strong Refrain from distorting.
- For a long service life, it should be non-corrosive.
- Installation is made simple by the lightweight design.
- The building was constructed in accordance with the criteria of the Uniform Plumbing Code
Fiberglass septic tank installation
A fiberglass septic tank can be constructed with a gravel backfill or a concrete inclusion to provide a complete solution. Some fiberglass septic tank manufacturers want to do a wet pit test prior to installing their tanks. In this test, the tank will be buried in gravel, and the water will be pumped out into the gravel to increase the pressure of the groundwater. If it passes the test, the results will reveal which tank has the best overall performance. However, for reputable manufacturers such as ourselves, our goods already have their own set of criteria that demonstrate to our customers that they are receiving high-quality tank performance.

Septic Tanks – Fibreglass Versus Plastic
Fibreglass is rigid and does not bend. The main problem with many plastic tanks is that they are not sturdy enough, and if the groundwater level is greater than the tank’s base when it is emptied, the tank will deform and become unfit for function. Because groundwater pressures can be quite high, some distort even when completely full. As they bend, always inwards, the volume of the device is substantially decreased, rendering it unable to function correctly. Lids are no longer a good fit. In addition, drain connections snap off, forcing drain spigots to bend downward, causing the drains to lose their gradient and the system to “back-up.” Both chambers can overflow into each other when the internal baffle walls become disconnected from the walls of the other chamber.
- In the photograph below, you can see the deformation that can occur when low-quality plastic systems are put in moist ground conditions.
- In this yard, there were 50 old septic tanks that had been scrapped.
- MDPE was never meant to be used for subterranean installations, yet it is quite inexpensive to purchase and install.
- By immersing the septic tank in a pool, you will not be able to determine its strength.
- Groundwater is unable to do so because it is trapped by the weight and density of the earth above it, resulting in a huge rise in pressure.
- Because concrete is not watertight, groundwater works its way through the concrete and bends the tank regardless of how well it is constructed.
- The only safe approach to install a plastic septic tank, according to our expertise, is to construct a watertight chamber for the tank to be placed in.
- Any other technique of installing a plastic septic tank runs the danger of distorting it, but this operation is quite costly.
This premium one-piece fibreglass structure comes with a 25-year guarantee and is built to last. The Class 1Crystal Septic Tankoption may be erected with a gravel backfill, even in places with high groundwater levels, without the risk of deformation or cracking, according to the manufacturer.
Plastic Sewage Treatment Plant Tanks
The EN12566-3 Tank Strength Test is only required for the CRUSH strength and is not required for any other strength. When the tank is subjected to this test, it is weighted on top with increasing weight until it collapses. This test does not accurately simulate the impacts of groundwater since groundwater exerts pressure from all directions, including from the tank’s base and the tank’s sidewalls. Although there is an EN12566-3 test for groundwater pressure resistance – the WET PIT TEST – unfortunately, this test is OPTIONAL, and many manufacturers, particularly those who are unsure about their tanks, prefer to forego this crucial test!
The tank is covered in gravel and water is pushed into the gravel to simulate groundwater pressures.
Some tank manufacturers claim that their tank has passed a wet pit test even if it has only been partially submerged in water throughout the testing process.
This does not meet our standards, in our opinion.
- Is the tank in possession of an EN12566-3 Wet Pit Certificate? What was the depth of the water surrounding the tank? How long was the tank subjected to testing?
Because you have no way of knowing what your groundwater will do to the tank, don’t buy their wastewater treatment plant if they refuse to inform you. In order to serve as an example, the VORTEX sewage treatment facility has been awarded the Wet Pit Certificate. Over a three-week period, it was immersed in groundwater to a level above the entrance pipe (the water level was just 300mm below ground level).
The Benefits of Fiberglass Septic Tanks
Do you have a septic system that needs replacing? A new fiberglass system is a fantastic alternative. Listed below are some of the advantages of investing in these types of systems:
- Exceptionally Simple to Install – One of the most significant advantages of purchasing a fiberglass septic tank is that they are really simple to put in place. A conventional container may be transported in a pickup truck and is simple to position when it is inserted into its respective hole. Additionally, the tank can be swiftly adjusted by a single person. Simply said, when you have damage to a fiberglass septic tank, you can repair it fast and efficiently using common components. When it comes to concrete tank restoration, anybody who has done so understands that a professional mason is typically required in order for the restoration to be accomplished effectively. Fiberglass is a durable material – Septic tanks made of concrete or metal are susceptible to deterioration from prolonged contact to sewage and the gases that accompany it. Due to the fact that fiberglass is impervious to water, you won’t have to worry about tree roots penetrating your tank.
After you have completed the installation of your new tank, you can rely on the professionals at Mid Florida Septic Inc. to offer you with effective pumping services. We are confident in our ability to assist you when it comes to septic companies in Windermere, FL and the surrounding towns.
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 had a fracture in it, and the vendor was going to replace it. 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 composed 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 more fees 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.
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.
Pros: I believe that the weight and expense of a plastic tank are the most significant advantages it has over other solutions.
This implies that you may purchase anything from one of the major home improvement stores and carry it yourself using a truck or trailer to your destination.
The fact that they do have some inherent flex makes them less prone to breaking 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.
Lifespan:The average lifespan of a plastic septic tank should be 30 to 40 years, given that it is properly maintained.
Average Cost:Prices vary depending on your location, of course, but it seems the price for plastic septic tanks run about $1 per gallon — or about $1,000 for a 1,000 gallon tank and about $1,500 for a 1,500 gallon tank.
However, I think fiberglass wins out over plastic on at least one point… Pros:Because fiberglass does not flex, these septic tanks are structurally more sound than plastic.
They are relatively light at about 300-350 pounds for the typical household sized tank.
The fiberglass tanks may not be available at the big box home improvement stores, if you were hoping for that.
Fiberglass septics should last a good 30 – 40 years, when properly maintained.
Concrete Septic Tanks Precast Concrete Septic Tank Concrete septic tanks are very common in older houses and in new builds.
When built on-site, the hole is dug in your yard, and a form (like a mold) is built in the hole.
You can also get a pre-cast septic tank.
Think of concrete barricades used as freeway dividers during construction, or sewer pipes, or even bridge pieces — they were all made elsewhere, not at the actual site they are used at.
Pros:Concrete septic tanks have a couple big advantages over plastic or fiberglass tanks — they are stronger and last longer.
So as long as it does not crack or separate (see Cons, below), it can last indefinitely.
They can withstand the internal and external pressures better than alternatives.
Cons:There are a couple downsides to a concrete septic tank.
This was the situation with the tank at our house when we purchased it.
Another issue, which you may or may not consider to be a downside, is the weight.
This will require a large truck and hoist or crane to deliver and install it.
While you may not plan on living in your home for 40 years, it is good news if you are purchasing a house with a concrete tank because it is likely it will serve you well for many years to come.
However, due do its enormous weight, a much larger truck and a crane will be necessary to deliver and install a concrete septic tank.
Pros: Lack of availability makes listing the pros a bit of a moot point, but nevertheless, they do seem to be a bit stronger than plastic, and certainly lighter than concrete.
They get very weak and crumble away.
Not only is that super nasty, it’s also deadly since septic tanks contain deadly gasses like methane.
It might be worth it to change that tank out sooner rather than later, before rust and corrosion create huge problems.
These are the conclusions I’ve come to after all my research.
However, if lower cost is a factor in your decision, or if large trucks will have trouble getting to your location, then a fiberglass tank seems to be the best option.
Finally, for the ultimate in lowest cost and ease of getting the tank yourself, the plastic tanks will fit that bill. Now that you have a new septic tank on the way, here aresome tipsto properly maintain it.

Guide to Plastic or Fiberglass Septic Tanks
Inspection of plastic or fiberglass septic tanks is an important part of the onsite wastewater disposal system’s overall operation. The plastic septic tank seen in this image is courtesy of thenaturalhome, which may be found at the URL provided further down this page. Unlike concrete (cracks) or steel (rust) septic tanks, fiberglass or plastic septic tanks are extremely resistant to some of the difficulties that can arise with these materials, such as home-made (collapse). Septic tanks made of plastic, on the other hand, may require additional considerations, notably during installation and perhaps when the septic tank is being drained out of its plastic or fiberglass casing.
- When a fiberglass or plastic septic tank is opened for pumping, it is possible to discover that the effluent level has dropped significantly. Examine the tank bottom to determine whether a plastic plug that was originally attached to the tank has been missing after it has been emptied. During the pumping of her septic tank, one of our readers wrote in to tell us that the pumping process itself loosened and removed a blockage from the tank’s bottom. The loss was found some years later, when the tank was reopened for pumping for the first time in several months. The plug was reinstalled once it had been cleaned. In any case, do not enter a sewer tank for any purpose, including removing a plug unless you are properly educated, equipped with the necessary breathing apparatus, and have a companion monitoring your back. Septic tank methane gas dangers may be devastating in minutes if not addressed. Damage sustained during installation: A fiberglass septic tank may sustain damage during installation, for example, if it is dropped or struck by heavy machinery while being installed. It is possible that the break and leak that resulted from this may not be noticed until the septic tank is pumped later in the year. Make that there are no missing drain plugs or that the effluent levels are abnormally low. If a fiberglass or other light-weight material septic tank is left empty after installation or after pumping, and if the septic tank is located in an area with wet soils or rising ground water, the tank may float up out of the ground, causing plumbing connections to be broken and the tank itself to be damaged.

Fiberglass Septic Tank
In the event that you are going to construct a new tank or need to replace an existing one, fiberglass septic tanks may be a smart option for you. Any type of tank will degrade in the ground over time, but fiberglass tanks provide a number of distinct advantages.
The Advantages Of A Fiberglass Septic Tank
- They are less heavy than concrete tanks and can be moved and placed considerably more easily than the latter. This can be a significant benefit in regions where a large truck and crane boom are inconvenient to access. The transport of some fiberglass tanks is even possible with a pickup truck. These tanks are built to be extremely solid and resilient, allowing them to last for an extended period of time. Their resistance to corrosive substances and attacks is superior than that of concrete. Damage to a steel tank may be less difficult to repair than damage to a concrete tank. Tree roots will not be able to penetrate fiberglass septic tanks in the same way that they can with concrete.
One issue with these sorts of tanks is that they have a tendency to float in regions when groundwater levels are quite high. Due to the fact that they are significantly lighter than concrete, it is important to properly tie them to the earth. The size of your tank will be determined by the same criteria that determine the size of other types of tanks. For example, the size of the house, the number of tenants, and the number of bathrooms are all important considerations. Once you’ve transported your tank to its final destination, it will need to be installed.
When it comes to ensuring that it is done correctly, an experienced contractor is always the best option.
As a result of its numerous advantages, it is possible that it will be an excellent decision for you.

Concrete Septic Tanks Are Probably The Best Option — Build With a Bang
Concrete Septic Tank with a Capacity of 1000 Gallon When it comes to septic systems, whether you’re in the market for a new system or just need a replacement tank, you’ve arrived to the perfect location. As part of our recent investigation into different types of septic systems that are available for your house, we decided that it would be a good idea to also investigate the many types of septic tanks now available on the market. The following are the three most common types of septic tanks that are easily accessible for installation: When constructed properly and maintained on a regular basis, the majority of concrete septic tanks may endure for up to 40 years.
- Waste flow, home size, square footage, number of bedrooms, number of bathrooms, and a few other factors are taken into consideration in septic tank size recommendations and charts.
- Septic tanks are available in a variety of sizes, and you can even obtain tanks that are smaller than 1000 gallons; however, we recommend that you go with a tank that is at least 1000 square feet in size.
- Consult with a licensed expert before purchasing or installing any equipment if you’re going to install a new septic tank or septic system for the first time.
- ” A few of states are now requiring 1000 gallon tanks as the minimum size requirement.
The popularity of the concrete septic tank can be attributed to its strength, weight, and longevity. For more precise information on durability, concrete septic tanks that are correctly constructed have a lesser probability of breaking, cracking, or floating.
Check out these 6 septic systems available for your home.
Nowadays, most concrete septic tanks are sold with a two compartment design, as opposed to the earlier style one compartment tank that was more common previously. Two compartment tanks tend to perform a better job of filtering and separating waste than one compartment tanks, which is why septic experts advocate them over a single compartment tank. All compartments are constructed with access for cleaning and pumping, regardless of the number of compartments in the system. Because it can readily handle most 0-3 bedroom dwellings, a 1000 gallon septic tank is the standard size for domestic applications.
Heavy Duty Options
Many tanks are also available in “high duty” configurations, which generally have a reinforced top and bottom. Purchasing the heavy-duty version may be a wise decision in the case that a vehicle, agricultural equipment, or other large piece of heavy machinery passes over the tank area.
Because of the size and weight of concrete septic tanks, they must be installed by a qualified specialist. These tanks are constructed of the hardest materials available, and while they are extremely durable, their installation necessitates the use of enormous, heavy machinery. If the intended or present site of your concrete septic tank does not allow for heavy machinery access, you may want to investigate a fiberglass or plastic (polyethylene) tank. Due to the fact that the majority of concrete tanks are precast, their sizes, weights, and dimensions are all different.
Lifespan and Durability
The method by which the concrete septic tank was constructed will have an impact on its long-term function. High-quality concrete, adequate water sealing, and the use of structural steel goods such as mesh and rebar will provide additional support, strength, and structural integrity to the structure. Keep in mind that concrete septic tanks are more prone to cracking and leaking than their plastic and fiberglass equivalents when exposed to exceptionally cold temperatures and pressures. Most concrete septic tanks have a lifespan of up to 40 years if they are constructed properly and serviced on a regular basis.
1000 Gallon Concrete Septic Tank
Septic tanks of 1000 gallon capacity or larger are the most typical size for household usage, as they can readily fit most 0-3 bedroom dwellings. Size Weight: The weight of each concrete tank is different. Some of the most common 1000 gallon concrete precast tanks are around 5′ 1″ X 8′ 2″ X 5′ 8″ in size and weigh almost 9,000 lbs. Others are approximately 5′ 1″ X 8′ 2″ X 5′ 8″ in size and weigh almost 9,000 lbs. Here are some examples of Jensen Precast projects completed in various cities around the United States.
1250 Gallon Concrete Septic Tank
Generally speaking, a 1250 gallon tank is a good choice for mid-size homes with 3-4 bedrooms. Size and weight: The sizes and weights of all concrete tanks are different. 1250 gallon concrete precast tanks are typically 5′ 9″ x 8′ 6″ x 5’8″ in size, with some of the more common models being 5′ 9″ x 8′ 6″ and others measuring 5′ 8″. The typical weight of a 1250 gallon concrete tank is 11,000 lbs, however this might vary depending on the distributor. Approximately 11 1/2 feet in depth, however this varies according on the distributor, state, and local statutes.
In addition, many of these bigger tank sizes are so massive that rebar and wire mesh are required within the walls and between layers to provide additional strength, stability, and durability.
1500 Gallon Concrete Septic Tank
Generally speaking, a 1500-gallon tank is the most popular size for large homes with five or more bedrooms. Size and weight: The sizes and weights of all concrete tanks are different. The dimensions of some of the most common 1500 gallon concrete precast tanks are around 6′ x 10′ 9″ x 5′ 5″ in length and width. The typical weight of a 1500 gallon concrete tank is 12,000 lbs, which is rather heavy. Approximately 12 feet in depth, however this varies according on the distributor, state, and local statutes.
When installing a septic tank, an inlet baffle should be put on the inlet part closest to the point at which the sewer tank joins from the house structure to the tank. Due to the fact that it prevents scum and oils from blocking the entrance pipe, the inlet baffle is critical to the overall health and effectiveness of the septic system. The intake baffle is a bottle neck that is especially designed to do the following:
- In order to prevent the breakdown process from being disrupted, it is necessary to slow the effluent entering the septic tank. A fast rate of inflow of effluent might cause problems by mistakenly combining the settled solid waste with oils, scum, and effluent. Make sure no sewage gases are allowed to enter the sewer line. These gases have the potential to infiltrate back into a home or structure, generating a foul odor.
Every septic tank should be equipped with an exit baffle that is connected to the discharge line. The outlet baffle functions as a bottle neck in the same way as the inlet baffle, but in the opposite direction. It is meant to:
- Preserving the septic tank by keeping scum, oils, and solid waste contained inside
- It is necessary to prevent the discharge of waste items other than wastewater into the output pipe, drain field, and leach field.
All effluent from the septic tank must be clear of solid waste before it may be discharged. Other than that, the solids and oils will pollute the drain field/leach field and result in backups and pollutants entering the surrounding environment. Ensure that your baffles are correctly built and that they are not in need of repair by consulting with a licensed septic technician before doing anything else. Septic tanks made of fiberglass or polyethylene (polyethelyene) are also a suitable option, especially if your location has specialized environmental requirements.
In contrast to concrete septic tanks, which normally need a vehicle equipped with a crane and boom, fiberglass and polyethylene septic tanks are quite simple to transport. Therefore, fiberglass and plastic tanks are frequently employed in places where concrete septic tank delivery vehicles are unable to reach the tanks. The majority of fiberglass and plastic septic tanks weigh roughly 300 pounds or more, however concrete septic tanks can weigh up to 20-30 times as much.
If you’re seeking for a less expensive alternative to concrete, fiberglass and polyethylene (polyethylene) are excellent choices. The majority of fiberglass and plastic septic tanks are thousands of dollars less expensive than concrete septic systems.
When compared to a concrete septic tank, both plastic and fiberglass septic tanks have a lower likelihood of breaking. Furthermore, because fiberglass and plastic are nonporous materials, there is typically no problem with tree or bush roots growing into the tank and generating leaks as a result of root damage. Having said that, due to the tank’s smaller profile and lighter material composition, caution must be used during installation because heavy gear might easily harm it. Tanks made of fiberglass or plastic can be destroyed in the same way as concrete tanks can if too much weight is placed on the surface above them.
Despite the fact that plastic and fiberglass tanks are quite resilient, they can nonetheless leak under specific circumstances.
As a result, it’s important to contact with a septic installation specialist before making a final decision on a certain material. The size of the lot, the position of the tank, the amount of ground water, and the weather can all influence the selection.
Plastic and fiberglass have a number of advantages, but they can also be troublesome. Yes, the lightweight character of these materials makes them perfect for installation, but same lightweight nature also results in a high level of buoyancy in the final product. It is possible that during a storm, a plastic or fiberglass tank can get dislodged from its couplings, causing considerable damage to the septic system and the homeowner’s property, with repair costs in the hundreds of dollars. A simple solution is to place a concrete slab on top of the tank to help weigh it down.
If you reside in an area with a high groundwater table, consult with a specialist to ensure that the higher water table will not cause harm to your fiberglass or plastic tank.
