Which Is Better A Fiberglass Or Plastic Septic Tank? (Solved)

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. Also, they’re prone to leaking and cracking when compared to plastic septic tanks.


  • By using a fiberglass septic tank, you avoid issues such as bending inwards, reduced volume, and lids no longer fitting. Fiberglass tanks often come with extended warranty, unlike their plastic counterparts. In conclusion, fiberglass is a superior alternative to plastic and eliminates all the issues associated with plastic.

What is best material for 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.

What kind of septic tank lasts the longest?

Concrete septic tanks have the longest lifespan out of any septic tank material. While they are more expensive and sometimes difficult to install, it is for a good reason. A properly designed and installed concrete septic tank can last for anywhere from 40 years and beyond.

How long do plastic septic tanks 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.

Do plastic septic tanks last?

Poly septic tanks generally have a lower lifespan than concrete tanks. Plastic tanks usually have low effluent levels and will “float” when the water level is higher than usual. This “floating” can destroy your plumbing system and the septic tank itself.

How long do fiberglass septic tanks last?

Fiberglass Septic Tank Cost 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.

Which type of septic tank is good?

1. Concrete Septic Tank. Concrete septic tanks are massive and are generally pre-casted for easy installation. These precast concrete tanks have specific gravity around 2.40, which makes it strong to withstand the buoyant forces when placed in the ground.

How often should a septic tank be replaced?

Typical lifespan is in excess of 30 years for GRP, PE and concrete tanks. Assuming optimal conditions of install and use, you could expect the following: Steel septic tanks have a life expectancy of 15 to 20 years.

How can I make my septic tank last longer?

How to Extend the Life of Your Septic System

  1. Do conduct annual inspections.
  2. Do conduct regular tank cleaning.
  3. Do know where your septic system is.
  4. Do keep septic system maintenance records.
  5. Do reduce water load into your septic system.
  6. Do avoid draining other water sources into your leach field.

What will ruin a septic system?

Any paper products like tissues, paper towels, tampons, or sanitary products, even some heavier toilet paper, will clog your system if you flush enough of it. Wet wipes are another product that you should never flush into a septic system.

How big of a septic tank do I need for a 3 bedroom house?

The correct size of the septic tank depends mostly on the square footage of the house and the number of people living there. Most residential septic tanks range in size from 750 gallons to 1,250 gallons. An average 3-bedroom home, less than 2500 square feet will probably require a 1000 gallon tank.

How deep can you bury a plastic septic tank?

Whatever the case may be, knowing the depth of your septic tank can be a difficult thing given the circumstances, especially if you don’t know where the lids are. The general rule of thumb is that most septic tanks can be buried anywhere from four inches to four feet underground.

Should bath water go into septic tank?

In MOST household septic systems, yes. Probably 98%+ of septic systems receive all of the waste water from the house – tub, shower, sinks, washing machine, dishwasher, etc.

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.

Can a septic system last forever?

How long does a septic system last? On average, a new septic system will last for 20-30 years. Soil quality – the quality of soil will determine how durable your septic tank is. For instance, acidic groundwater can corrode a concrete septic tank.

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).

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?

  1. However, to break it down fast, concrete septic tanks are excellent for their durability and long life.
  2. 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.
  3. 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.
  4. 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.
  5. As a result, I’ve included some information on pricing as well.
  6. 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.
  7. 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.

The typical 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.

  1. However, I believe that fiberglass outperforms plastic on at least one aspect.
  2. External influences should not have an impact on them.
  3. There aren’t any downsides in this case.
  4. The life expectancy of this product is similar to that of plastic tanks.
  5. 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.
  6. They can either be constructed on-site or pre-cast.
  7. 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 seen any stores that sell steel sewage treatment tanks, although these look to be rather 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 want to remain in your home for an extended period of time and if large trucks can readily reach your site, I believe it is worthwhile to spend the extra money to have a concrete septic tank installed for the added piece 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.

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
  • Economical


  • 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.

  1. Rubber boot seals are particularly attractive since they are flexible and maintain a seal even after backfilling and settling has taken place.
  2. 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.
  3. The compartment walls are normally cast in one piece with the tank, similar to how the tank is constructed.
  4. When it comes to horizontal joints, preformed flexible joint sealants consisting of butyl rubber or asphalt-based compounds are utilized to seal them.
  5. 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.
  6. 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
  • Economical


  • 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.

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 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.

The Size

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.

The Style

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.

The Price

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.

The Durability

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.

The Maintenance

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

In order to extend the retention duration of wastewater in a pool, the owner must ensure that the DC water produced by the fiberglass septic tank is converted into circulating water. If the sewage in the pool and sedimentation sludge are allowed to interact for a longer period of time, more microorganisms will be produced, which will speed up the breakdown process.

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.

  • Installation of this magnitude will take no more than 1-2 days.
  • Septic tank made of fiberglass, 1710 x 965 mm.

4 Types of Septic Tanks – HomeAdvisor

The characteristics of each type of septic tank are crucial to understand whether you’re deciding which type of tank to use in conjunction with your septic system or solving a problem with your existing tank. Each installation option has its own set of pros and limitations, just like any other installation. Knowing the relative advantages and disadvantages of each option will assist you in making the right selection while establishing, repairing, or replacing your septic tank. Please keep in mind that most of these issues are the consequence of improper septic maintenance or installation.

The cost of an inspection might vary significantly based on a variety of criteria.

  • Solid Waste Container— Solid waste containers made of concrete are prone to cracking and even separation. These fissures, which are usually extremely durable for several decades, might appear sooner if a poor quality concrete mix was used or if the septic system has not been adequately maintained. These gaps will allow effluence (waste) to leak out of the concrete septic tank and/or allow groundwater to seep in through the tank’s drainage system. Either scenario is undesirable. The system may get clogged as a result of a blockage. Runoff is harmful, but it will not be discovered by a typical dye test since it is invisible. If a concrete septic tank is not physically inspected, it is possible that the problem will not be discovered until it is too late and major difficulties have developed. Tanks made of steel are the least long-lasting and most unpopular of the available tank options. They are intended to survive no more than 20-25 years, although they can succumb to rust even earlier than that. Steel top covers have the potential to rust through, allowing an unwary individual to fall into the tank. It is possible to change these covers without having to replace the complete tank. If you’re purchasing a property or already live in one that has a steel septic tank cover, personally viewing the cover will not necessarily provide you a clear indicator of the general state of your tank in the long run. As with any septic tank, pay particular attention to the baffles (entry and exit points) because they are the first to corrode in most cases. Fiberglass/Plastic Septic Tank—Unlike steel and concrete septic tanks, plastic septic tanks are virtually immune to the corrosion and cracking that occurs in steel and concrete septic tanks. Nonetheless, they have their own set of difficulties that should be kept an eye out for. In some cases, a low effluent level might indicate that a blockage at the bottom of the tank has gotten dislodged. Pumping should be performed even if the effluent level seems to be normal throughout the process
  • Nevertheless, any clogs should be carefully checked after the pumping. It is possible that the process of pumping a septic tank will be sufficient to remove a clog.
  • In spite of the fact that plastic septic tanks are more resistant to the chemical processes that occur naturally in a septic system, their lower weight makes them more prone to structural damage. It is necessary to install the tank with care in order to avoid damage to the tank. It is important to take careful notice of the land above the tank. Avoid driving any vehicles over the tank’s filling station. During periods of wet soil, the lighter can also cause the tank to shift in its position in the ground. Occasionally, a plastic septic tank may emerge from the earth, destroying pipes along the way.
  • Using oxygen to help in the degradation of the effluent is what aerobic septic tanks are all about, according to the manufacturer. They also necessitate the use of power. When a septic system fails, aerobic septic tanks are most frequently utilized to replace it. They can also, on occasion, minimize the amount of space necessary for their drain field. Aerobic septic tanks are generally two to three times more expensive than conventional septic tanks, but their high efficiency can result in significant savings in terms of reclaimed land in the drain field and a longer tank life. The capacity of an aerobic septic tank to function has nothing to do with its long-term dependability. A more regular and more thorough maintenance schedule is required for an aerobic septic system. Because of its more intricate breakdown structure, there is a greater possibility that something may go wrong. However, if the system is properly maintained, its effectiveness will allow you to keep your effluent under control for an almost unlimited period of time.
  • Important Caution: Exercise extra caution when in the vicinity of open or uncovered sewage tanks. Falling into a sewage tank will almost always result in death due to asphyxiation. The simple act of leaning over a septic tank might lead you to pass out.

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.

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.

Installation Requirements

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

Because of the size and weight of concrete septic tanks, they must be installed by a professional. These tanks are constructed of the hardest materials available, and while they are extremely durable, their installation necessitates the use of enormous, heavy machinery. Consider a fiberglass or plastic (polyethylene) septic tank if the intended or present placement of your concrete septic tank does not allow for easy access by heavy machines. Due to the fact that the majority of concrete tanks are precast, their sizes, weights, and dimensions are all unique.

1000 Gallon Concrete Septic Tank

Because of its size and weight, all concrete septic tanks must be professionally installed. These tanks are constructed of the hardest materials available, and while they are extremely durable, they need the use of enormous, heavy machinery to be installed. If the intended or present placement of your concrete septic tank does not allow for easy access by heavy machinery, you may want to investigate a fiberglass or plastic (polyethylene) tank.

Because most concrete tanks are prefabricated, their sizes, weights, and dimensions are all different. Keep in mind, however, that all of these specs are approximations and are subject to change depending on state and local regulations.

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.

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.

Inlet Baffles

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.

Outlet Baffles

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.


There must be no solid waste in any of the wastewater discharged from the septic tank. Otherwise, the sediments and oils will pollute the drain field/leach field, resulting in backups and the release of pollutants into the atmosphere. Ensure that your baffles are correctly installed and that they are not in need of repair by consulting with a licensed septic technician before doing anything else!

Alternatively, fiberglass and polyethylene (polyethelyene) septic tanks are a viable option, particularly in certain local circumstances. septic tank made of heavy-duty polyethylene material

Cost Effectiveness

All septic tank effluent must be clear of solid waste before it may be discharged. Otherwise, the sediments and oils will pollute the drain field/leach field, producing backups and pollutants to reach the environment. If you have any doubts about whether your baffles are correctly placed or whether they could be in need of repair, consult with a licensed septic technician. Septic tanks made of fiberglass or polyethylene (polyethelyene) are also a viable option, depending on the circumstances in your location.


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.

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.
