Modern septic tanks are made out of either industrial plastic or precast concrete.
- 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 type of concrete is used for septic tanks?
Precast Concrete Septic Tanks Are The Clear Choice 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 cement type would be ideal for use in a septic tank designed for an environment with an extremely high sulfate content?
Type II-V. This type of cement gains strength more slowly than Type I cement and is used primarily in concrete exposed to severe sulfate attack – where soils or groundwaters have a high sulfate content. This cement is particularly effective for structures such as sewage treatment plants and septic tanks.
How thick is the concrete on a septic tank?
The exterior walls of the septic tank are made of concrete, normally 4 inches thick. The concrete is either a minimum of 4,000 or 5,000 PSI concrete. A 1,200-gallon tank can weight as much as 8,000 pounds, so these are not items a homeowner can install on his own.
Which type of material is used for the base of a septic tank?
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 long do cement septic tanks last?
Inspectapedia estimates that a steel tank baffles will rust out in 15 to 20 years and may collapse if driven over, but a concrete tank will last 40 years or more as long as the wastewater is not acidic. It’s important to consider the life expectancy of a drain-field, too.
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.
How do you lift a concrete septic tank?
There is a pry bar between the lid and the top of the tank. The handle should be held on top of the lid by your helpers. Push down on the pry bar to open the concrete lid.
What materials are needed for a septic system?
A typical septic system has four main components: a pipe from the home, a septic tank, a drainfield, and the soil. Microbes in the soil digest or remove most contaminants from wastewater before it even- tually reaches groundwater. Your Septic System is your responsibility!
Are concrete septic tanks reinforced with rebar?
3 reinforcing rod (rebar). (11) The concrete tank and tank lid shall be reinforced by using a minimum reinforcing of six-inch by six-inch No. (13) A minimum 28-day concrete compressive strength of 3,500 pounds per square inch shall be used in the construction of the septic tank, concrete access riser and riser cover.
Are plastic septic tanks better than concrete?
Plastic septic tanks are watertight and are immune to water-based corrosion. They are also rust-resistant. Plastic tanks are less prone to cracking since plastic is flexible, and thus a plastic septic tank does not crack as much as a cement septic tank. Plastic septic tanks are more hygienic than cement tanks.
What are the dimensions of a 500 gallon concrete septic tank?
500 Gallon Siphon Tank Package Overall Length: 79” Overall Width: 48” Height to center line of inlet: 48” Height to center line of outlet: 48”
Are septic tanks made of concrete?
Modern septic tanks are made out of either industrial plastic or precast concrete. Some tanks are also made of fiberglass, though this material is uncommon in the United States. Concrete is inherently watertight, whereas plastic and fiberglass must undergo extra processes in order to hold water.
Does shower water go into septic tank?
From your house to the tank: Most, but not all, septic systems operate via gravity to the septic tank. Each time a toilet is flushed, water is turned on or you take a shower, the water and waste flows via gravity through the plumbing system in your house and ends up in the septic tank.
How much does it cost to pump a septic tank?
How much does it cost to pump out a septic tank? The average cost is $300, but can run up to $500, depending on your location. The tank should be pumped out every three to five years.
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.
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.
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. Baffles at the input and output of the system aid in the separation of solid waste items, oils, and scum from the effluent.
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.
How to Build a Concrete Septic Tank
Home-Diy If your home is not adjacent to a public sewer system, you may be required to install a septic tank and a lateral drainage system in order to treat your household waste properly. Pre-cast concrete septic tanks are easily accessible, but the cost of transport and installation is prohibitively high.
- Survey of land grade
- Excavation equipment
- Steel reinforcing bars and ties
- Steel hooks
- Manhole with cover
Although you may walk on top of the septic tank and drive a riding mower over it, you should avoid driving a car or tractor over it. If you are not familiar with the process of pouring concrete, you should hire a concrete contractor.
Form and pour as soon as feasible once excavation is completed. The soil might shift, causing a trench or pit to collapse. Maintain a safe distance between excavation and construction sites and keep children and animals out of the area. Septic tank construction is an involved operation that should be left to the specialists. As long as the local construction rules allow it, you may install your own septic tank on your property.
- Establish where your septic tank is located, as well as its depth. The fall of the sewage pipe that travels from the home to the intake outlet on the septic tank will be determined by your local construction codes. In addition, make sure that the water discharge line from the septic tank to the lateral leech fields has the proper drop needed by code. When determining the site, a survey crew will examine the gradient of your land. Excavate the hole into which you will pour the concrete for the concrete tank. A backhoe will be used to remove the soil from the pit and to build trenches for the pipe that will be used to connect the septic tank to the main sewer line. Fill the pit’s bottom with a minimum of 6 inches of sand or gravel to prevent it from sinking. In order to limit the likelihood of shifting or breaking, it is necessary to stabilize the base beneath the septic tank. First, form and pour the tank’s floor, installing steel reinforcing to ensure that the tank meets or exceeds local building regulations. Install the vertical steel rebar that will be used to brace the tank walls while the floor is being poured. Incorporating metal rebar into a wet concrete floor will provide a strong structural link between the walls and the floor. Install horizontal rebar rods and attach them using rebar ties to keep the structure stable. Despite the fact that the building code is mandatory here, normal rebar spacing is between 12 and 16 inches
- After the tank framework has been checked by the building inspector, order concrete. The building of septic tanks is highly regulated in most towns since a leaking tank has the potential to damage streams and water tables. Additionally, before you pour the walls, create allowances for the intake pipe and the drainage pipe. Separately, on a flat sand bed, form the tank cap to fit the tank. The cap’s measurements should correspond to those of the septic tank, and you will place a manhole in the form before pouring the concrete. You’ll also need steel reinforcement and four massive steel hooks that are positioned at each corner of the cap and extend all the way through the concrete to complete the project. The cap should be lifted from the sand bed with a crane by latching it onto the four steel hooks and carefully positioned atop the tank before covering the cap with earth
What is Concrete Septic Tank & Detail
Septic Tanks: The wastewater from residential washrooms, faucets, showers, and toilets is disposed of in a concrete septic tank, which is a cost-effective method of generating trash. This type of septic tank is typically seen in well-known locations where more sophisticated sewage systems are not utilized. Solid waste created by houses is separated from water via a process known as filtration. Concrete septic tanks are available in a variety of sizes, with the majority having a height of around 9 feet and a length of approximately 9 feet.
Concrete septic tanks are the most often utilized septic tanks because they are the most readily accessible and economical to build when compared to other types of septic tanks.
The poured tanks are readily demolished depending on the location in which they are placed and the weather conditions that prevail.
The precast tanks have shown to be more dependable and have not cracked readily over a lengthy period of time. They are not simple to install; it will cost time, money, and expertise.
Role of a Septic Tank:
It goes without saying that a septic tank is an important part of your plumbing system. With the aid of a drainage and toilet system, a compartment holding building is constructed to collect wastewater. The biochemical treatment of solid and liquid influent begins in the building, with liquid sewage being discharged to a drain field covered by dirt, underneath of the building yard, after which the treatment is completed. Solid particles sink to the bottom of the septic tank, while light particles such as greases, oils, and fats rise to the surface of the tank.
Filtration of Septic Tank:
The filter in a septic tank is a terrific, cost-effective, and simple solution for extending the life of a concrete septic tank that is not equipped with a filtration system. Inspection, pump access, and cleaning are all easily accessible. Risers are used to hold lids that allow Carbon filters to be used. If the amount of decreasing drainage gas is sufficient. Leaching buildings may be used in a variety of ways, such as decreasing energy consumption and expanding the area of leach fields. All septic tanks are constructed in a correct manner and are 100 percent waterproof.
The production process includes a rigorous quality control system, as well as specific methods that are commensurate with the technology used in septic tanks. All of the pipe connections, including the inlet and output, are gasket-sealed. While in operation, the septic tanks and septic tank systems are non-toxic and environmentally friendly, since they protect groundwater and are long-lasting. The use of concrete septic tanks provides for a longer exit flow time while also lowering velocity across a vast region and requiring a lower liquid level for effluent.
The septic tank also has the capacity to run the pipe for both high and low pressure.
6 ADVANTAGES OF CONCRETE SEPTIC TANKS
As a homeowner, it’s possible that you don’t give much thought to your septic tank. The most of the time, your tank will be hidden beneath the earth. When you discover that you require a septic tank repair, you are forced to confront the unpleasant but unavoidable reality of having to replace this entirely necessary home waste disposal machine. Concrete septic tanks provide six distinct advantages over other types of septic tanks, which we examine in detail in this blog post. MATERIALS USED IN COMMON SEPTIC TANKS Historically, brick or stone septic systems were used to construct local septic systems.
- Modern septic tanks are composed of either industrial plastic or precast concrete, depending on the use.
- Because plastic tanks have a cheaper initial cost than concrete tanks, many homeowners chose this tank type without doing a thorough cost comparison.
- The advantages of concrete over other building materials are as follows: Both types of septic tanks are capable of performing their functions, but each material has its own set of pros and disadvantages.
- compliance with all applicable building codes and regulations All structures in the United States that are compatible with a local septic system are permitted to have a concrete tank installed.
- It is possible that a plastic tank will not be permitted in a certain vicinity to groundwater owing to the danger of flotation and pollution.
- INHERENT WATERTIGHTNESSConcrete is essentially waterproof, whereas plastic and fiberglass must go through additional procedures in order to be watertight at all.
If the tank begins to fill up too rapidly, it will need to be pumped.
In certain cases, plastic tanks can endure for enough time to be considered a temporary investment, but they will most likely need to be replaced in the not-too distant future.
LOW-RISK INSTALLATION PROCESSBecause plastic septic tanks are less robust than concrete septic tanks, the machinery used to carry and install them may cause damage to the tanks.
While concrete is usually never harmed during the installation process, it may become prone to cracking in severe conditions, such as when exposed to high-pressure corrosive chemicals or when exposed to high-temperature temperatures.
There is no danger of the tank collapsing during the pumping process.
Plastic septic tanks, on the other hand, are susceptible to collapse during the pumping process.
In spite of the fact that they must be pumped several times, concrete tanks do not collapse.
Even if you are still uncertain, it is recommended that you consult with a competent septic system professional in order to make the best selection for your home.

4 Types of Septic Tank Materials
1 minute is allotted for reading A septic tank is a tank that collects sewage and treats it through bacterial decomposition. Septic tanks are often buried underground. A decent septic tank is essential for a successful septic system, and the quality of the tank is determined by the type of material utilized in its construction. To choose a decent septic tank, it is necessary to be familiar with the many types of septic tank materials, as well as their pros and disadvantages, which are briefly discussed below.
- Septic tanks are available in a variety of materials, including concrete, steel, plastic, and fiberglass.
1. Concrete Septic Tank
Concrete septic tanks are large and heavy, and they are often pre-cast to make installation easier. The specific gravity of these precast concrete tanks is around 2.40, which makes them sturdy enough to withstand the buoyant forces that occur when they are put in the ground. In addition, their strength progressively grows over time. Concrete septic tanks are classified into two varieties depending on their structural configuration: single structure tanks and all-in-one systems. Single structure tanks are the most common form of concrete septic tank.
Some of the benefits and drawbacks of precast concrete septic tanks are discussed in further detail below.
- The enormous weight of concrete septic tanks means that they will not float if the water table is close to the tank level. Concrete septic tanks have a very long life cycle, and they may last for several decades if properly maintained. They are sturdy enough to withstand heavy machinery and are not readily destroyed. They are resistant to corrosion.
- When compared to other types of tank materials, it is more expensive. When something is damaged, it is difficult to fix. The transportation and installation of pre-cast concrete septic tanks necessitates the use of large equipment, making the process more complicated. The use of a low-quality concrete mix results in the formation of fissures, which allow the effluent to escape.
2. Steel Septic Tanks
When compared to other forms of tank materials, concrete is more expensive. Damaged equipment is difficult to fix. In order to transport and install pre-cast concrete septic tanks, large equipment is necessary, making installation a more difficult task. Using a low-quality concrete mix results in the formation of fissures, which allow the effluent to escape.
- The considerable weight of steel septic tanks ensures that they will not float when the water table is close to the tank. In addition, they have strong resistance to buoyant forces
- Due to the ease with which steel corrodes, the lifespan of steel tanks is significantly reduced when compared to alternative septic tank materials. A high price for a low level of durability The removal of rusted steel septic tanks from the earth is a difficult task. Their deteriorating condition may put them in potentially unsafe circumstances.
Fig. 3: Corroded steel sewage treatment tank
3. Plastic Septic Tanks
They are also known as poly septic tanks since they are made of polyethylene plastic, which is the material from which they are composed of. Because they are lighter in weight and rustproof than concrete and steel septic tanks, they are an excellent alternative to these materials. Plastic septic tanks are less cumbersome to carry and install because of their reduced weight. Plastic septic tanks have specific gravities in the range of 0.97 to 0.98, which is lower than the specific gravity of water, causing the tank to float when the water table is close to it.
The following are some of the pros and downsides of using plastic septic tanks.
- When compared to other types of septic tank materials, plastic septic tanks are more cost-effective. They are simple to handle and install
- They are chemically resistant
- And they are lightweight. Abrasion and corrosion resistance
- Good resistance to breaking
- When the water table is close to the tank bottom, it may push the tank higher, causing plastic septic tanks to float as a result of the weight of the water in the tank. They are susceptible to harm when exposed to extreme circumstances
- Heavy weights should not be placed or moved over the plastic septic tank since this may cause it to distort and change its shape, which may eventually result in the tank exploding owing to the high pressure within.
4. Fiberglass Septic Tank
Using fiber reinforced polymers, fiberglass septic tanks are manufactured (FRP). They are similar in appearance to plastic septic tanks, but the addition of glass fiber reinforcement makes them far stronger than plastic tanks. They are also rather light in weight and simple to move around. A consequence of the tank’s decreased weight is the possibility of it floating or moving, which may be avoided by properly securing the tank to the ground.
Some of the pros and disadvantages of fiberglass septic tanks are as follows: They are lightweight, durable, and cost-effective. Fig. 5: Septic Tank Made of Fiberglass
- Septic tanks made of concrete and steel are more expensive. When opposed to plastic septic tanks, concrete septic tanks have more robustness. High durability
- Corrosion resistance
- And watertightness.
- In the same way that plastic septic tanks are unable to withstand buoyant pressures, fiberglass septic tanks will float or move when the water table is brought closer to them.

If your septic tank is not operating properly, you should replace or repair it as soon as possible. It is possible that your septic tank is not operating properly, causing your entire plumbing system to be interrupted. This might result in you placing yourself and your family in risk, as well as causing damage to your home or garden.
- There is a good probability that you will be replacing your present septic system with a new one within a few years.
- This is due to the fact that the septic tank you select will be used to service your plumbing system in the future.
- Septic tanks made of sorplastic.
- Knowing their advantages and disadvantages will assist you in selecting the one that best matches your needs and fits inside your budget.
Plastic Septic Tanks
- The purchasing price of plastic septic tanks is less expensive than that of concrete septic tanks
- Thus, they are more cheap. Plastic septic tanks are simple to install since they are lightweight
- They take just a small number of people to complete the job and require little time and equipment. As a result, installation costs are reduced. Poly septic tanks are lightweight and versatile, making them ideal for travel. This implies that they may be placed in a variety of locations. Plastic septic tanks are waterproof and impervious to corrosion caused by water-based substances. Additionally, they are rust-resistant. Plastic tanks are less prone to cracking than cement tanks because plastic is more flexible than cement
- As a result, a plastic septic tank does not break as often as a cement septic tank It is more sanitary to use polyethylene septic tanks than than cement tanks
- Plastic tanks are delivered fully assembled and ready to be fitted.
Since plastic septic tanks have a lower purchase price than concrete septic tanks, they are more inexpensive than concrete septic tanks; The fact that plastic septic tanks are lightweight makes them simple to install; they take just a small number of people to complete the job and consume less time and money. Consequently, installation costs are reduced. Poly septic tanks are lightweight and versatile, making them ideal for transporting and setting up. Because of this, they may be used in a variety of settings.
These products are also resistant to rusting.
Compared to cement septic tanks, plastic septic tanks are cleaner and more sanitary.
- Plastic tanks are not as durable as concrete and are quickly crushed by the weight of the container. Alternatively, they might be crushed by the weight of thick dirt or by vehicles passing over the areas where they are buried. Plastic tanks are also susceptible to the environment, which means that they might burst or crack as a result of changes in soil vibrations and environmental conditions, among other things. Solid-waste disposal systems made of cement, on the other hand, are significantly less responsive to environmental changes. Plastic septic tanks are more susceptible to deterioration than cement septic tanks because they break or wrap more frequently. In comparison to cement septic tanks, plastic tanks require more care to keep them operating properly. Concrete tanks have a longer lifespan than poly septic tanks
- Nevertheless, they are less durable. In most cases, plastic tanks have low effluent levels and will “float” if the water level in the tank is greater than typical. This “floating” can cause extensive damage to your plumbing system as well as the septic tank itself. Plastic septic tanks are not authorized for use in all states
- However, in certain areas they are.

Concrete Septic Tanks
- Cement septic tanks outlast plastic tanks in terms of durability and, if maintained properly, may survive for a lengthy period of time. In the right circumstances, with regular draining and good maintenance, a cement septic tank can endure up to 40 years or more. Cement septic tanks are resistant to changes in the environment, such as tree roots or shifting soil conditions. Concrete tanks are not adversely affected by the weight that is placed on top of them. Comparing cement septic tanks to plastic septic tanks, cement tanks are far more durable and require little maintenance. The fact that concrete tanks are highly hefty and contain large effluent levels means that they are impervious to “floating.” There are no restrictions on using cement tanks in the United States
- They are permitted in every state.
- Concrete septic tanks are more expensive to purchase and install than plastic septic tanks, mostly due to the weight of the concrete tanks. Concrete tanks are more difficult to carry and install than plastic tanks due to the fact that they are awkward and more big in comparison. Therefore, the cementseptic tank installation necessitates the use of heavy equipment and requires a significant amount of time. Cement tanks are also more difficult to repair and install than other types of tanks. As your cement tank is broken, it is more difficult to repair it efficiently when compared to plastic tanks. Compared to plastic tanks, cement septic tanks are more prone to corrosion due to the fact that they fracture or corrode as the tanks age, particularly if they are not properly maintained.
Selecting a Septic Tank
For many homeowners in Atlanta, GA, cement is the go-to material since it is permitted in all 50 states in the United States, including Georgia. It has been a long time since cement has been the preferred building material due of its resistance to damage caused by shifting or heaviness. Plastic septic tanks, on the other hand, are less expensive than concrete septic tanks when it comes to cost comparison. It is recommended that you use a plastic tank when you live in a distant place since cement tanks cannot compete with the simplicity with which it can be installed and transported.
Septic tanks made of cement are not recommended for use in areas with significant acidity in the soil.
Despite the fact that there are several aspects to consider when deciding between a plastic and a cement septic tank, examine your location and scenario and choose the choice that feels best for your property.

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
- Because of the density of concrete, it offers more resistance to buoyancy. Installation requirements that are less onerous. Large capacity are available in a variety of sizes, including extremely large ones. Design for deeper burial and traffic rating are both options
- Nevertheless, the former is the more common choice. The ability to personalize is more straightforward

Why A Concrete Septic Tank?
Concrete septic tanks are preferable than fiberglass or plastic septic tanks because they are waterproof and heavy duty, making them the preferred storage vessel for on-site sewage storage and treatment over the other materials. In the United States, there are over 40 million septic systems in operation. Septic systems rely on the soil surrounding the septic tank, which is the major component in a septic system, to filter the wastewater discharged from the tank. Concrete septic tanks are also well-known for the following characteristics, in addition to the advantages described above:
- Strength improves with time
- Ease of installation
- Low susceptibility to damage during the backfill process

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.
- Solid Waste Container— Solid waste containers made of concrete are prone to cracking or even separation. When a low-quality concrete mix is used or the septic system isn’t properly maintained, these cracks might appear sooner than they should and can last for several decades. These gaps will allow effluence (waste) to leak out of the concrete septic tank and/or allow groundwater to seep in via the tank’s openings. The outcome is undesirable in either scenario. A snag in the system’s flow might cause it to stall. A typical dye test will not identify runoff, which is quite harmful. Because of the manual inspection required for concrete septic tanks, 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 tank options available. It is possible that they will corrode even before they reach their intended lifespan of 20-25 years. An unaware individual may fall into the tank as a result of rusting through steel top coverings. Replacement of these covers does not necessitate a complete tank replacement. If you’re purchasing a property or already live in one that has a steel septic tank lid, personally viewing the cover will not necessarily provide you a clear idea of the general state of your system. Always pay special attention to the baffles (entry and exit points) when maintaining a septic tank, since these are the first to corrode. Using a fiberglass or plastic septic tank has several advantages over using steel or concrete septic tanks, including the fact that plastic septic tanks are almost immune to corrosion and cracking. Nonetheless, they have their own set of potential issues that should be monitored. Lower than normal effluent levels may indicate that a stopper at the bottom of the tank has gotten loose. It is still necessary to physically verify any clogs after pumping, even if the effluent level seems to be normal throughout the pumping process. A septic tank pumping operation may be sufficient to remove a clog at times.
- 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.
- Using oxygen to help in the breakdown of the effluent is what aerobic septic tanks are all about, according to the name. Aside from that, they require power. When a septic system fails, aerobic septic tanks are most typically utilized to replace it. Occasionally, they are able to minimize the amount of space necessary for their drainage system. 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 area in the drain field and life expectancy. When it comes to durability, the ability of an aerobic septic tank is irrelevant. Regular and significant maintenance are required for an aerobic septic system, which is more expensive. As a result of its more sophisticated breakdown mechanism, there is a greater likelihood that something may go wrong. But if the system is kept in good working order, it will be able to keep your effluent under control for an almost limitless period of time.

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.
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.
However, I believe that fiberglass outperforms plastic on at least one aspect.
External influences should not have an impact on them.
There aren’t any downsides in this case.
The life expectancy of this product is similar to that of plastic tanks.
In addition, the cost is around $1 per gallon, or approximately $1,000 for a 1,000-gallon tank and approximately $1,500 for a 1,500-gallon tank.
They can either be constructed on-site or pre-cast.
The concrete is then poured into the mold, where it is allowed to set and cure while still in the mold.
A different place makes them, and they are delivered to your location for installation.
Pre-cast firms create molds for concrete tanks and other concrete objects, pour the concrete into the molds, and then store the concrete tanks and other concrete items on site until they are transported to the building site.
Concrete will not corrode, rust, or dissolve under normal conditions.
Additionally, the strength of concrete septic tanks will outperform that of plastic or fiberglass septic tanks.
The huge weight of a concrete tank is a possible disadvantage, which you can read about further below, but it is also a good element since the incredible weight means that they are significantly less likely to shift in the ground as they are being built or installed.
First and foremost, they have the potential to break or split, enabling sewage to spill out (although this is unlikely to occur for many years).
The seller was previously aware that it had cracked at one of the top corners and that he would not be permitted to sell the house until it was replaced.
A concrete septic tank with a capacity of 1,000 gallons weighs approximately 8,000 pounds (or 4 tons).
Longevity: If properly cared for, they should easily last 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.
