Precast Concrete Septic Tanks vs. Plastic Septic Tanks

When it comes to selecting a septic tank for your property, there are several alternatives to consider. First and foremost, you want to be sure that the tank you choose has the appropriate capacity for your home. After that, you’ll want to be certain that you select a tank that will give years of dependable service for you and your family members. A precast concrete septic tank is the most suitable option. Precast septic tanks provide several advantages over other types of tanks, such as plastic, steel, or fiberglass.

The Benefits Of A Precast Septic Tank

  • The tanks weigh a great deal. While this may be considered a disadvantage by some, we feel it is one of the most significant advantages of using carbon fiber over other materials. Because of the weight of the precast concrete septic tank, it will never “float” to the surface, which is something that certain lesser weight tanks may accomplish in certain scenarios. Precast concrete septic tanks have a specific gravity of 2.40, which makes them more resistant to buoyant forces than other septic tank materials. HDPE has a specific gravity of 0.97, which is very high. For anchoring structures composed of more buoyant materials, further labor-intensive and time-consuming on-site preparation is required. When selecting a septic tank for your property, it is important to consider the following factors: Precast septic tanks do not rust, which is a major concern. Steel tanks, as well as portions of some plastic and fiberglass tanks, are extremely susceptible to corrosion and failure. Unlike traditional concrete, precast concrete gradually gains strength over time. Other materials, such as steel or high-density polyethylene (HDPE), can degrade and lose their strength. The contents of precast concrete storage tanks may be pumped out without the risk of the tank collapsing. The process of installation is basic and uncomplicated. Shea Concrete offers a staff of tank installers that have completed hundreds of tank installations in the past. We are well-versed in site preparation and are capable of overcoming virtually any installation challenge. In addition, we have vehicles that are fitted with hoists and can even crane a tank over a house when necessary
  • Concrete, along with water, is the most widely utilized building material on the planet. This natural substance is non-toxic, ecologically safe, and comprised entirely of natural materials, making it an excellent choice for septic tanks. Concrete is employed in a variety of applications throughout the country and has no negative impact on the quality of groundwater or surface water. During the installation process, plastic tanks are susceptible to damage. In most cases, the installation process is to blame for tank failures
  • Precast concrete tanks can be made watertight if they are manufactured in accordance with the National Precast Concrete Association’s “Septic Tank Manufacturing” Best Practices Manual and/or ASTM C 1227, “Standard Specification for Precast Concrete Septic Tanks.” In accordance with these industry standards, which Shea Concrete adheres to, the required processes to be followed during the fabrication of waterproof tanks are specified. It is never acceptable to drive an automobile over a plastic storage tank. This may set restrictions on the location of the tank and leaching area on your land.

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
  • Durability
  • Ease of installation
  • Low susceptibility to damage during the backfill process

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.

Polyethylene/Polypropylene

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.

Advantages

  • 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

Disadvantages

  • Installation is simplified by the fact that poly tanks are lighter than concrete and may be used in difficult-to-reach locations. 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 conventional steel. It is possible for contractors to deliver themselves, eliminating the need for a boom truck or the need to wait for delivery. In order to prevent leaking seams and joints, the design is restricted. Economical

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.

  1. The assembling procedure must be meticulously carried out to ensure that the joint does not leak or split.
  2. While the glue is curing, the bolts are mostly employed to keep the pieces together while the adhesive cures.
  3. 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.
  4. If joints are not watertight, the functioning of the tank is significantly diminished owing to the greater danger of water invading the tank.

Advantages

  • 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

Disadvantages

  • 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

Concrete

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.

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. Additionally, precast tanks may typically accommodate extra components such as ATUs or pumps.

Advantages

  • Because of the density of concrete, it has a higher resistance to buoyancy. Installation requirements that are less stringent
  • The containers are available in a variety of sizes, including extremely large capacities. It is possible to build for a deeper burial and to have a traffic rating
  • It’s less difficult to customize
  • Economical

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.

  1. 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.

Advantages

  • 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.

Drawbacks

  • 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

Steel septic tanks are constructed of steel and are the least common nowadays due to the high cost and short lifespan of the tanks. Compared to other types of materials, steel septic tanks have the greatest potential for deterioration, which makes them the most problematic. If the top section of a steel septic tank becomes rusted, it will be unable to withstand any weights placed on top of it and will collapse at any time without warning.

As a result, caution should be exercised when checking steel septic tanks. Modern septic systems do not encourage the use of these types of tanks. Fig. 2: Septic Tank Made of Steel

Advantages

  • 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

Drawbacks

  • 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.

Advantages

  • 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

Drawbacks

  • 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.

5: Septic Tank Made of Fiberglass

Advantages

  • 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.

Drawbacks

  • 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.

Concrete vs Plastic Septic Tanks: Which is Better?

The septic tank on your property is one of the most important components of the whole plumbing system on your property. Septic tanks are designed to safely handle and manage all of the wastewater generated by your property. 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.

Plastic and concrete are the two most often used materials in the construction of septic tanks. Knowing their advantages and disadvantages will assist you in selecting the one that best matches your needs and fits inside your budget. Examine the merits and cons of each of these options separately.

Plastic Septic Tanks

Advantages

  • 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.

Disadvantages

  • 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

Advantages

  • 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.

Disadvantages

  • 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.

Concrete Septic Tanks Are Probably The Best Option — Build With a Bang

Concrete Septic Tank with a Capacity of 1000 Gallon When it comes to septic systems, whether you’re in the market for a new system or just need a replacement tank, you’ve arrived to the perfect location. As part of our recent investigation into different types of septic systems that are available for your house, we decided that it would be a good idea to also investigate the many types of septic tanks now available on the market. The following are the three most common types of septic tanks that are easily accessible for installation: When constructed properly and maintained on a regular basis, the majority of concrete septic tanks may endure for up to 40 years.

  • Waste flow, home size, square footage, number of bedrooms, number of bathrooms, and a few other factors are taken into consideration in septic tank size recommendations and charts.
  • Septic tanks are available in a variety of sizes, and you can even obtain tanks that are smaller than 1000 gallons; however, we recommend that you go with a tank that is at least 1000 square feet in size.
  • Consult with a licensed expert before purchasing or installing any equipment if you’re going to install a new septic tank or septic system for the first time.
  • ” A few of states are now requiring 1000 gallon tanks as the minimum size requirement.

The popularity of the concrete septic tank can be attributed to its strength, weight, and longevity. For more precise information on durability, concrete septic tanks that are correctly constructed have a lesser probability of breaking, cracking, or floating.

Check out these 6 septic systems available for your home.

Nowadays, most concrete septic tanks are sold with a two compartment design, as opposed to the earlier style one compartment tank that was more common previously. Two compartment tanks tend to perform a better job of filtering and separating waste than one compartment tanks, which is why septic experts advocate them over a single compartment tank. All compartments are constructed with access for cleaning and pumping, regardless of the number of compartments in the system. Because it can readily handle most 0-3 bedroom dwellings, a 1000 gallon septic tank is the standard size for domestic applications.

Heavy Duty Options

Many tanks are also available in “high duty” configurations, which generally have a reinforced top and bottom. Purchasing the heavy-duty version may be a wise decision in the case that a vehicle, agricultural equipment, or other large piece of heavy machinery passes over the tank area.

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

The method by which the concrete septic tank was constructed will have an impact on its long-term function. High-quality concrete, adequate water sealing, and the use of structural steel goods such as mesh and rebar will provide additional support, strength, and structural integrity to the structure. Keep in mind that concrete septic tanks are more prone to cracking and leaking than their plastic and fiberglass equivalents when exposed to exceptionally cold temperatures and pressures. Most concrete septic tanks have a lifespan of up to 40 years if they are constructed properly and serviced on a regular basis.

1000 Gallon Concrete Septic Tank

Septic tanks of 1000 gallon capacity or larger are the most typical size for household usage, as they can readily fit most 0-3 bedroom dwellings. Size Weight: The weight of each concrete tank is different. Some of the most common 1000 gallon concrete precast tanks are around 5′ 1″ X 8′ 2″ X 5′ 8″ in size and weigh almost 9,000 lbs. Others are approximately 5′ 1″ X 8′ 2″ X 5′ 8″ in size and weigh almost 9,000 lbs. Here are some examples of Jensen Precast projects completed in various cities around the United States.

1250 Gallon Concrete Septic Tank

Generally speaking, a 1250 gallon tank is a good choice for mid-size homes with 3-4 bedrooms. Size and weight: The sizes and weights of all concrete tanks are different. 1250 gallon concrete precast tanks are typically 5′ 9″ x 8′ 6″ x 5’8″ in size, with some of the more common models being 5′ 9″ x 8′ 6″ and others measuring 5′ 8″. The typical weight of a 1250 gallon concrete tank is 11,000 lbs, however this might vary depending on the distributor. Approximately 11 1/2 feet in depth, however this varies according on the distributor, state, and local statutes.

In addition, many of these bigger tank sizes are so massive that rebar and wire mesh are required within the walls and between layers to provide additional strength, stability, and durability.

1500 Gallon Concrete Septic Tank

Generally speaking, a 1500-gallon tank is the most popular size for large homes with five or more bedrooms. Size and weight: The sizes and weights of all concrete tanks are different. The dimensions of some of the most common 1500 gallon concrete precast tanks are around 6′ x 10′ 9″ x 5′ 5″ in length and width. The typical weight of a 1500 gallon concrete tank is 12,000 lbs, which is rather heavy. Approximately 12 feet in depth, however this varies according on the distributor, state, and local statutes.

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.

Mobility

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.

Cost Effectiveness

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.

Durability

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.

Float

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 Long Will My Septic System Last?

The presence of a septic tank is an absolutely necessary component for any residence that is not linked to the municipal or city sewage system. Septic systems, which capture and filter sewage and household wastes, may keep your home clean for many years if properly maintained. The type of material utilized in the construction of the septic tank may have an impact on the system’s long-term endurance. Fortunately, you may pick from a broad array of septic tank materials, including concrete, plastics, steel, and fiberglass, to meet your specific needs.

Septic Tank Made of Concrete Tanks made of precast concrete are the favored choice for the majority of homes, particularly in rural areas.

Concrete septic tanks are available in two configurations: single-structure tanks and all-in-one systems.

Installation of the huge concrete blocks may need the use of heavy gear such as cranes.

  • Concrete is rust and corrosion resistant, allowing the septic tank to survive for a longer period of time. The tanks are hefty enough to withstand the effects of buoyancy
  • Yet, Concrete tanks are usually designed to withstand heavy traffic. The septic system may be simply customized to meet your specific requirements.
  • Because of the requirement for specialist equipment, the installation may be prohibitively expensive. When something is broken, it might be difficult to fix.

Septic Tanks Made of Plastic Plastic septic systems are made by molding polyethylene or polypropylene into a certain shape. The tanks are small and lightweight, and they are simple to assemble. In places with a high water table, the reduced density, on the other hand, may present problems. Because of their specific gravity of 0.98, the tanks have the potential to float out of the ground if the water level is sufficiently high.

Rust and corrosion resistance are two important characteristics of plastic septic tanks. The ribbed or corrugated design of the tank may improve the structural performance of the tank. Advantages

  • Plastic septic tanks are easier to install
  • The tank is chemical- and rust-resistant
  • Plastic tanks are more economical than concrete systems
  • It is possible that the plastic tank will float in locations with high water tables. The capabilities are frequently reduced
  • To ensure structural integrity of the plastic septic tank, it may be necessary to follow certain installation guidelines.

Septic Tanks Made of Fiberglass Fiberglass systems are comparable to plastic septic tanks in that they are lightweight. The tanks are reinforced with glass fibers, which makes them significantly stronger than polyethylene plastic tanks. Fiberglass is a lightweight material that is corrosion resistant and simple to install. Because of the lightweight nature of fiberglass septic tanks, adequate ground anchoring may be required in order to avoid movement in soils with high water tables, for example.

  • Fiberglass is lightweight and easy to install, making it a good choice for small areas. The glass fibers are resistant to rust and chemical deterioration
  • They are also lightweight. It is possible to purchase tanks with bigger capacity.
  • Because of its minimal weight, the tank has the potential to float above the ground. Installation criteria that are quite stringent in order to maintain the structural integrity of the tank

When it comes to a septic tank, what is the best material to use? The most appropriate material for your septic tank project may be determined by your personal tastes and needs. Because of its weight, concrete tanks may be the most buoyant-resistant of all the types of tanks. Because they do not necessitate the use of specialist equipment, fiberglass or plastic installations are a good option for homeowners with limited floor space. It is possible that you may want the services of a professional septic tank installation business.

Avoiding Septic Tank Problems: Choosing the Right Material

By ensuring that your septic tank is constructed of the proper materials, you may avoid septic tank troubles. The majority of septic tanks are made of concrete, fiberglass, polyethylene, or steel that has been covered with a protective coating. Pre-fabricated septic tanks with a capacity of less than 6,000 gallons are often used for small septic systems. Larger septic tanks are either built in place or assembled on-site from pre-manufactured components in order to save time and money. In order to properly install concrete tanks in a system, specialized cranes must be used to lift and lower the tanks into place.

  • A concrete tank, with its additional weight, would be more suitable for tanks built in areas where there is a lot of ground water, wet soil, or other situations that might cause tanks to float.
  • It is also crucial to be aware of the maximum depth permitted by the tank manufacturer – concrete tanks, for example, are often strengthened to withstand higher depths than other tank materials.
  • Over time, the presence of hydrogen sulfide and sulfuric acid can cause concrete and the rods that strengthen the concrete to corrode (note: this is not the case with aerobic septic tanks).
  • Tanks made of PVC and polyethylene are not harmed by these gases, while tanks made of nylon are impacted.
  • Tank manufacturers must adhere to precise specifications in order to ensure that the predicted weights do not break or collapse the tank, and seams must be waterproof in order to accommodate fluctuating soil saturations.
  • This is also crucial in order to prevent water from entering the tank from the outside, which might cause the tank to become hydraulically overloaded and disrupt the treatment process.
  • Tank collapses have also been connected to a tank’s inability to keep water out of the tank.

To summarize, there are a variety of considerations to consider while picking a septic tank material. Choosing the proper material will aid in the prevention of issues with your system.

Modern Septic Tanks: Materials, Types, and Accessories

While septic tanks used to be made of a variety of materials (including wood), today’s tanks are primarily constructed of high-performance materials that have been proved in the field. Whether you haven’t had a septic system in decades or this is your first time owning one, you’ll want to learn everything you can about septic tanks before making an offer on a rural property. While only one component of a septic system, the tank is an extremely vital component that requires regular maintenance, such as pumping and cleaning.

  1. Materials for the Tank The body of a contemporary septic tank is normally constructed of a material that is designed to withstand the forces that attack it.
  2. Concrete, fiberglass, and plastic are some of the most widely utilized materials.
  3. However, despite the fact that concrete is a very inexpensive tank material, it is not regarded the most long-lasting contemporary septic tank material due to two drawbacks: it is porous and it is prone to cracking.
  4. The second type of erosion is caused by sewage gases.
  5. As a result, the gas might transform into acid, which eats away at the concrete.
  6. Fiberglass As a result of the fact that fiberglass is largely impervious to acid assaults, it may be used to prevent any of the erosion that concrete may be subject to over time.
  7. However, because these tanks are lighter than concrete, they must be properly secured to prevent them from drifting away when the ground becomes flooded.

Although plastic is frequently regarded as harmful to the environment due to the fact that it takes an inordinate amount of time to decompose, that same characteristic might be a lifesaver in this application.

Types The kind of septic tank that is put in your property may be determined in part by the peculiarities of your home’s setting.

Listed here are some of the most common types of septic tanks that you’ll find on the market and in your garden.

A one-compartment tank is the most basic design, and it has been in use for many decades.

There are two compartments.

Some jurisdictions (such as the state of Washington) require that new tanks contain at least two chambers to be compliant.

There are three compartments.

Others may just have three chambers for processing, in order to boost the overall efficiency of the system even further.

Components of a baffle Designed to be installed at the entrance or exit of the septic tank, a baffle or sanitary tee directs and controls wastewater flow.

Plastic tees are preferable in a contemporary tank, although both styles serve the same purpose in a variety of situations.

At the outlet, a tee or baffle stops floating particles from entering the outflow pipe and clogging it.

Components for gaining access to the tank Older septic tanks may have hidden lids that are difficult to reach and access, making it difficult to get access to each tank compartment.

As you can see, the design, substance, and appurtenances of a contemporary septic tank can vary significantly from one tank to the next.

Types of Septic Systems

Septic system design and size can differ significantly from one neighborhood to the next, as well as throughout the country, due to a variety of variables. Household size, soil type, slope of the site, lot size, closeness to sensitive water bodies, weather conditions, and even municipal ordinances are all considerations to take into consideration. The following are 10 of the most often encountered septic system configurations. It should be noted that this is not an exhaustive list; there are several additional types of septic systems.

  • Septic Tank, Conventional System, Chamber System, Drip Distribution System, Aerobic Treatment Unit, Mound Systems, Recirculating Sand Filter System, Evapotranspiration System, Constructed Wetland System, Cluster / Community System, etc.

Septic Tank

This tank is underground and waterproof, and it was designed and built specifically for receiving and partially treating raw home sanitary wastewater. Generally speaking, heavy materials settle at or near the bottom of the tank, whereas greases and lighter solids float to the surface. The sediments are retained in the tank, while the wastewater is sent to the drainfield for further treatment and dispersion once it has been treated.

Conventional System

Septic tanks and trench or bed subsurface wastewater infiltration systems are two types of decentralized wastewater treatment systems (drainfield). When it comes to single-family homes and small businesses, a traditional septic system is the most common type of system. For decades, people have used a gravel/stone drainfield as a method of water drainage. The term is derived from the process of constructing the drainfield. A short underground trench made of stone or gravel collects wastewater from the septic tank in this configuration, which is commonly used.

Effluent filters through the stone and is further cleaned by microorganisms once it reaches the soil below the gravel/stone trench, which is located below the trench.

Chamber System

Gravelless drainfields have been regularly utilized in various states for more than 30 years and have evolved into a standard technology that has mostly replaced gravel systems. Various configurations are possible, including open-bottom chambers, pipe that has been clothed, and synthetic materials such as expanded polystyrene media. Gravelless systems can be constructed entirely of recycled materials, resulting in considerable reductions in carbon dioxide emissions during their lifetime. The chamber system is a type of gravelless system that can be used as an example.

The key advantage of the chamber system is the enhanced simplicity with which it can be delivered and built.

This sort of system is made up of a number of chambers that are connected to one another.

Wastewater is transported from the septic tank to the chambers through pipes. The wastewater comes into touch with the earth when it is contained within the chambers. The wastewater is treated by microbes that live on or near the soil.

Drip Distribution System

An effluent dispersal system such as the drip distribution system may be employed in a variety of drainfield configurations and is very versatile. In comparison to other distribution systems, the drip distribution system does not require a vast mound of dirt because the drip laterals are only placed into the top 6 to 12 inches of soil. In addition to requiring a big dosage tank after the sewage treatment plant to handle scheduled dose delivery of wastewater to drip absorption areas, the drip distribution system has one major disadvantage: it is more expensive.

Aerobic Treatment Unit

Aerobic Treatment Units (ATUs) are small-scale wastewater treatment facilities that employ many of the same procedures as a municipal sewage plant. An aerobic system adds oxygen to the treatment tank using a pump. When there is an increase in oxygen in the system, there is an increase in natural bacterial activity, which then offers extra treatment for nutrients in the effluent. It is possible that certain aerobic systems may additionally include a pretreatment tank as well as a final treatment tank that will include disinfection in order to further lower pathogen levels.

ATUs should be maintained on a regular basis during their service life.

Mound Systems

Using mound systems in regions with short soil depth, high groundwater levels, or shallow bedrock might be a good alternative. A drainfield trench has been dug through the sand mound that was erected. The effluent from the septic tank runs into a pump chamber, where it is pumped to the mound in the amounts recommended. During its release to the trench, the effluent filters through the sand and is dispersed into the native soil, where it continues to be treated. However, while mound systems can be an effective solution for some soil conditions, they demand a significant amount of land and require regular care.

Recirculating Sand Filter System

Sand filter systems can be built either above or below ground, depending on the use. The effluent is discharged from the septic tank into a pump compartment. Afterwards, it is pushed into the sand filter. The sand filter is often made of PVC or a concrete box that is filled with a sand-like substance. The effluent is pushed through the pipes at the top of the filter under low pressure to the drain. As the effluent exits the pipelines, it is treated as it passes through the sand filtering system.

However, sand filters are more costly than a standard septic system because they provide a higher level of nutrient treatment and are thus better suited for areas with high water tables or that are adjacent to bodies of water.

Evapotranspiration System

Evaporative cooling systems feature drainfields that are one-of-a-kind. It is necessary to line the drainfield at the base of the evapotranspiration system with a waterproof material. Following the entry of the effluent into the drainfield, it evaporates into the atmosphere. At the same time, the sewage never filters into the soil and never enters groundwater, unlike other septic system designs. It is only in particular climatic circumstances that evapotranspiration systems are effective. The environment must be desert, with plenty of heat and sunshine, and no precipitation.

Constructed Wetland System

Construction of a manufactured wetland is intended to simulate the treatment processes that occur in natural wetland areas. Wastewater goes from the septic tank and into the wetland cell, where it is treated. Afterwards, the wastewater goes into the media, where it is cleaned by microorganisms, plants, and other media that eliminate pathogens and nutrients. Typically, a wetland cell is constructed with an impermeable liner, gravel and sand fill, and the necessary wetland plants, all of which must be capable of withstanding the constant saturation of the surrounding environment.

As wastewater travels through the wetland, it may escape the wetland and flow onto a drainfield, where it will undergo more wastewater treatment before being absorbed into the soil by bacteria.

Cluster / Community System

In certain cases, a decentralized wastewater treatment system is owned by a group of people and is responsible for collecting wastewater from two or more residences or buildings and transporting it to a treatment and dispersal system placed on a suitable location near the dwellings or buildings. Cluster systems are widespread in settings like rural subdivisions, where they may be found in large numbers.
