A typical residential septic tank is usually about 4.5 feet wide x 8.0 feet long x 6 feet tall. Your septic tank may be a different size however.
- On average, septic tanks are 4.5 feet wide, 8 feet long, and 6 feet tall. The number of bedrooms and number of people in your home will determine the dimensions of the septic tank you need. 1,000-gallon septic tanks are 8 feet 2 inches long, 5 feet 8 inches wide, and 5 feet 1 inch deep.
What is standard size of septic tank?
Length of septic tank (L) should be taken as 9feet 9 inches or 9.75 feet. Breadth of septic tank (B) should be taken as 6 feet 3 inches or 6.25 feet. The standard height (D) of septic tank should be taken as 5 feet 9 inches or 5.75 feet.
How deep and wide is a septic tank?
Septic tanks are typically rectangular in shape and measure approximately 5 feet by 8 feet. In most cases, septic tank components including the lid, are buried between 4 inches and 4 feet underground. You can use a metal probe to locate its edges and mark the perimeter.
How do I determine the size of my septic tank?
Consider the Size of Your Property The larger your home, the larger the septic tank you’re going to need. For instance, a house smaller than 1,500 square feet usually requires a 750 to 1,000-gallon tank.
How wide is a septic tank lid?
Locate The Lid Most septic tanks are rectangular and measure about 5 feet by 8 feet. Probe around the tank to locate its edges and mark the perimeter of the rectangle. A septic tank installed before 1975 will have a single 24-inch concrete lid in the center of the rectangle.
How often does a 1000 gallon septic tank need to be pumped?
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 deep should a septic tank be in the ground?
The general rule of thumb is that most septic tanks can be buried anywhere from four inches to four feet underground.
How often should a septic tank be pumped?
Inspect and Pump Frequently The average household septic system should be inspected at least every three years by a septic service professional. Household septic tanks are typically pumped every three to five years.
How long do septic tanks last?
A septic system’s lifespan should be anywhere from 15 to 40 years. How long the system lasts depends on a number of factors, including construction material, soil acidity, water table, maintenance practices, and several others.
Can you have a septic tank without a leach field?
The waste from most septic tanks flows to a soakaway system or a drainage field. If your septic tank doesn’t have a drainage field or soakaway system, the waste water will instead flow through a sealed pipe and empty straight into a ditch or a local water course.
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.
How far down is septic tank lid?
Often, septic tank lids are at ground level. In most cases, they have buried anywhere from four inches to four feet underground.
Do you need to pump both sides of a septic tank?
Septic tanks installed after the late 1980s have two compartments, and it is important to pump out both compartments each time. Most homeowners are unaware when their septic tank has two compartments; some companies use that to their advantage, charging to pump both sides of the tank but only actually pumping out one.
Septic Tank Sizes Chart: Common Tank Capacities and Measurements
High density polyethylene, abbreviated HDPE, is the most often used material for modern septic tanks, with concrete being the second most common material. HDPE is a heavy-duty grade polyethylene that is used to manufacture a variety of items, including septic tanks, which are available in both underground and above-ground configurations. Because of the robustness and adaptability of HDPE, plastic septic tanks are available in a broad range of volume capacities and measurement measurements to suit any application.
Plastic septic tanks are less expensive than concrete tanks, they are easier to carry and install, they are more resistant to cracking and weathering, and they are available in a variety of forms, volumes, and sizes to satisfy the exact demands of every application.
Our septic tank sizes chart contains the most often used tank capacity and measurements, which should be of assistance.

What Size Septic Tank Do I Need
The size of an underground septic tank is referred to as its total volume handling capacity in this article, and it will be discussed in further detail later in this article. For additional information on above-ground septic tanks and systems, see our page on above-ground septic tanks. The minimum septic tank capacity requirements are determined by a variety of variables. State, county, and/or city regulations may specify permitted tank sizes, as well as tank materials and installation.
The size of the septic tank will vary depending on whether it is intended for domestic or commercial usage; in this section, we will cover residential use.
Shortly stated, the required size of a septic tank will be determined by the following factors: (1) the specific septic system type; (2) local government requirements; (3) the compatibility of the ground geology; and (4) the anticipated volume of wastewater depending on the size of the residence.
However, this is not true.
Furthermore, plastic septic tanks will not corrode, are weatherproof, are waterproof, are less expensive, are lighter, and are easier to build. They will also not float if they are constructed appropriately.
1) The Specific Septic System Type
The size of an underground septic tank is referred to as its total volume handling capacity in this text, and it will be discussed in detail later. For additional information on these tanks and systems, please see our page on above-ground septic tanks. Minimum septic tank capacity requirements are determined by a variety of variables. State, county, and/or city regulations may specify acceptable tank sizes, as well as tank materials and location. Because of the importance of soil characteristics and geography in system efficacy, the size of drain fields and septic tanks can be influenced by the soil conditions.
- Septic tank systems in existence or to be installed might also influence the size of the tank that is necessary.
- Some people believe that polyethylene (also known as plastic) septic tanks are inferior to other types of septic tanks.
- When compared to concrete septic tanks, plastic septic tanks have far greater resistance to breaking.
- They will also not float if they are constructed properly.
- The following systems are available: conventional, gravity-fed, anaerobic systems
- Above-ground septic systems
- Pressure systems
- Anaerobic systems
- Mound systems
- Recirculating sand or gravel filters systems
- Bottomless sand filters systems
If your septic tank system is anything other than a traditional, anaerobic system, the instructions in this page may not be applicable in their entirety to your situation.
2) Local Government Regulations
The laws for septic tanks imposed by local governments vary greatly across the United States. In part, this is due to the significantly diverse soil geography and water features that exist from state to state and can even differ by a few miles in some cases. In order to determine the appropriate septic tank size and the best position on the land for installation, it is essential to consult with local government rules first. Take, for example, theWastewater Treatment Standards – Residential Onsite Systemsdocument from the New York State Department of Health, which provides a comprehensive informational overview of codes, rules, and regulations frequently promulgated by governing bodies, as well as common terminology and definitions in the industry.
3) Suitability of the Ground Geology
The subterranean soil type has a significant impact on the efficacy of the system and, consequently, the size of the septic tank. This topic is highly tied to the rules of the local government. In most cases, it is related to the standards and recommendations of a designated authority that regulates septic tank installations, which is typically the department of health. In order to determine whether or not the ground is suitable for a septic tank system, a trained specialist must come out to the prospective installation site and conduct a series of tests.
A perc test will assess whether or not the subterranean soil is capable of handling and filtering septic tank effluent in an appropriate manner.
Whether you are hiring an experienced professional or doing it yourself, it is your obligation to contact your local oversight agency and arrange for perc tests and/or ground area evaluations to be performed.
The findings of the analysis and testing will determine whether or not the chosen site is suitable, as well as whether or not a certain septic tank system or size is required.
4) The Expected Volume of Wastewater
The typical amount of wastewater that will be generated and that the septic tank will be able to manage is the most essential factor in determining the size of the septic tank that is required. In a home with simply a septic system, all wastewater is disposed of in the septic tank unless a separate system for managing greywater is in place to handle the waste. In order to calculate and approximate these values for residential dwellings, business structures, and facilities, extensive study has been carried out.
Starting with a 1000-gallon septic tank for residential usage, the advice is to go from there.
Some experts propose adding an additional 250 gallons of septic tank capacity for each additional bedroom over three bedrooms.
This is frequently the case when considering the situation collectively for the entire household rather than individually.
Minimum Septic Tank Capacity Table
For further information on the minimum septic tank capacity dependent on the number of residential bedrooms, please see the following table:
|Number of Bedrooms||Minimum Septic Tank Size||Minimum Liquid Surface Area||Drainfield Size|
|2 or less||1000 – 1500 Gallons||27 Sq. Ft.||800 – 2500 Sq. Ft.|
|3||1000 – 2000 Gallons||27 Sq. Ft.||1000 – 2880 Sq. Ft.|
|4||1250 – 2500 Gallons||34 Sq. Ft.||1200 – 3200 Sq. Ft.|
|5||1500 – 3000 Gallons||40 Sq. Ft.||1600 – 3400 Sq. Ft.|
|6||1750 – 3500 Gallons||47 Sq. Ft.||2000 – 3800 Sq. Ft.|
Take note of the following in relation to the table above:
- As defined by the State of New York, the Minimum Liquid Surface Area is the surface area given for the liquid by the tank’s width and length measurements. The range of Drainfield Sizes is depending on the kind of groundwater present. The State of Michigan provides the above-mentioned drainfield recommendations, which might vary greatly depending on local standards and terrain.
Additional Thought: Can a Septic Tank Be Too Big?
In the absence of consideration for cost, it is reasonable to ask: “Can a septic tank be too large?” The answer is a resounding nay. As long as the septic tank is placed appropriately, it is impossible for a septic tank to be too large; the only thing that can happen is that it is too little. According to the majority of suggestions, constructing a larger-capacity septic tank is frequently the safer and more preferable solution. The following are the reasons behind this:
- With a bigger septic tank, you can adapt for changes in household consumption, such as those caused by parties or long-term guests. In the event that your family grows in size or you want to make improvements to your house, such as adding more bedrooms and bathrooms or installing new plumbing fixtures, having a bigger septic tank can save you the expense of installing a new tank.
Takeaways | What Size Septic Tank Do I Need

Septic Tank Size: What Size Septic Tank Do You Need?
Septic tanks are used for wastewater disposal and are located directly outside your home. Private wastewater management is becoming increasingly popular in the United States, with more than 30 percent of newly constructed residences incorporating on-site wastewater management. Do you require septic tank installation and are unsure of the amount of septic tank you require? When establishing a septic tank, the most important element to consider is the type and size of septic tank that you will be installing.
A number of factors influence the size of a septic tank, which are discussed in this article.
Basics of Septic Tanks
Your septic system is a self-contained chamber that is designed to retain the wastewater generated by your home. A septic system is comprised of two major components: the soil absorption area or drain, and the holding tank. Septic tanks absorb solid waste when wastewater is discharged into them, resulting in the formation of an asludge layer at the septic tank’s base. A layer of soap residue, grease, and oil forms on the top of the water. The effluent or wastewater is contained within the intermediate layer.
To discover more about how a septic tank works, check out our page that goes into further detail on how a septic tank functions.
The Main Types of Septic Tanks
Before you start thinking about septic tank sizes, it’s important to understand the many types of septic tanks that exist.
- It is critical that you are familiar with the various types of septic tanks before contemplating septic tank sizes.
Concrete septic tanks are the most prevalent variety, but since they are so massive, you will need big and expensive equipment to build them. Fiberglass and plastic septic tanks are lighter than concrete and are therefore more suited for difficult-to-reach and distant locations. Before purchasing a septic tank, you should check with your local building department to learn about the rules and guidelines governing private wastewater management. You may also be interested in:Do you have a septic tank?
Why Septic Tank Sizes is Important
If the capacity of your home’s septic tank is insufficient to satisfy your requirements, it will be unable to handle the volume of wastewater generated by your home. As a result, a wide range of annoying difficulties can arise, including bad smells, floods, and clogs. Nonetheless, the most common consequence of a septic tank that is too small is that the pressure that builds up will cause the water to be released before it has had a chance to be properly cleaned. This suggests that the solid waste in the septic tank will not be sufficiently broken down, and will thus accumulate more quickly, increasing the likelihood of overflows and blockages in the system.
A septic tank that is too large will not function properly if it does not get the required volume of wastewater to operate.
If your septic tank is too large for your home, there will not be enough collected liquid to support the growth of the bacteria that aids in the breakdown of solid waste in the septic tank if the tank is too large.
What Determines Septic Sizes?
Here are some of the elements that influence septic tank sizes; keep them in mind when making your purchase to ensure that you get the most appropriate septic tank for your property.
Consider Your Water Usage
The most accurate and practical method of estimating the appropriate septic tank size for your property is to calculate the quantity of water you use on a regular basis. The size of the septic tank required is determined by the amount of water that can be held in it before being drained into the soil absorption field. In many places of the United States, the smallest capacity of septic tank that may be installed is 1,000 gallons or less. The following are the suggested septic tank sizes for your household, which are based on your household’s entire water use.
- Making an estimate of how much water you use on your property is the most dependable and effective technique to determine the appropriate septic tank size. Depending on how much water it can contain and how much will be discharged into the soil absorption area, the size of your septic tank will be determined. Septic tanks must be at least 1,000 gallons in capacity in several regions of the United States. The following are the suggested septic tank sizes based on the total amount of water used by your household.
Consider the Size of Your Property
Another factor to consider when determining the most appropriate septic tank size for your home is the square footage of your home. The size of your home will determine the size of the septic tank you will require. For example, a dwelling with less than 1,500 square feet typically requires a tank that holds 750 to 1,000 gallons. On the other side, a larger home of around 2,500 square feet will require a larger tank, one that is more than the 1,000-gallon capacity.
The Number of Bedrooms Your Property Has
An additional issue to consider is the amount of bedrooms in your home, which will influence the size of your septic tank. The size of your septic tank is proportional to the number of bedrooms on your home. The following table lists the appropriate septic tank sizes based on the number of bedrooms.
- In general, a 1-2 bedroom house will require a 500 gallon septic tank
- A 3 bedroom house will demand 1000 gallon septic tank
- A 4 bedroom house will require 1200 gallon septic tank
- And a 5-6 bedroom house would require a 1500 gallon septic tank.
The Number of Occupants
In general, the greater the number of people that live in your home, the larger your septic tank must be. In the case of a two-person household, a modest septic tank will be necessary. If your house has more than five tenants, on the other hand, you will want a larger septic tank in order to handle your wastewater more effectively and hygienically. When determining what size septic tank to purchase, it is important to remember that the size of your septic tank determines the overall effectiveness of your septic system.
As a result, it is critical that you examine septic tank sizes in order to pick the most appropriate alternative for your property in order to avoid these difficulties.
What size of septic tank do I need?
Probably one of the last things on your mind when you are constructing a new house is the location of your septic system. After all, shopping for tanks isn’t nearly as entertaining as shopping for cabinetry, appliances, and floor coverings. Although you would never brag about it, your guests will be aware if you do not have the proper septic tank placed in your home or business.
septic tanks for new home construction
Probably one of the last things on your mind when you are constructing a new house is the installation of an adequate septic system.
In the end, shopping for tanks isn’t nearly as entertaining as shopping for cabinetry, appliances, and floor coverings, respectively. Nonetheless, even if you never show it off, your guests will be able to tell if you don’t have the proper septic system in place.
planning your drainfield
Here are some helpful hints for deciding where to locate your drainfield when you’re designing it.
- Vehicles should not be allowed on or around the drainfield. Planting trees or anything else with deep roots along the bed of the drain field is not recommended. The roots jam the pipes on a regular basis. Downspouts and sump pumps should not be discharged into the septic system. Do not tamper with or change natural drainage features without first researching and evaluating the consequences of your actions on the drainage field. Do not construct extensions on top of the drain field or cover it with concrete, asphalt, or other materials. Create easy access to your septic tank cover by placing it near the entrance. Easy maintenance and inspection are made possible as a result. To aid with evaporation and erosion prevention, plant grass in the area.
a home addition may mean a new septic tank
Do not make any big additions or renovations to your house or company until you have had the size of your septic system assessed. If you want to build a house addition that is more than 10% of your total floor space, increases the number of rooms, or necessitates the installation of new plumbing, you will almost certainly need to expand your septic tank.
- For a home addition that will result in increased use of your septic system, your local health department will require a letter from you that has been signed and authorized by a representative of your local health department confirming that your new septic system is capable of accommodating the increase in wastewater. It is not recommended that you replace your septic system without the assistance of a certified and competent contractor.

common septic questions
Here are some of the most frequently asked questions by our septic customers.
How do I determine the size of my septic tank?
If you have a rectangular tank, multiply the inner height by the length to get the overall height of the tank. In order to find out how many gallons your septic tank contains, divide the number by.1337.1337
How many bedrooms does a 500-gallon septic tank support?
The exact size of the septic tank is determined mostly by the square footage of the house and the number of people who will be living in it. The majority of home septic tanks have capacities ranging from 750 to 1,250 gallons. A 1000 gallon tank will most likely be required for a typical 3-bedroom home that is smaller than 2500 square feet in size.
How deep in the ground is a septic tank?
Your septic system is normally buried between four inches and four feet underground, depending on the climate.
Sizes of Septic Tanks & Shapes
Most septic tanks are built of fiberglass, plastic, or reinforced concrete, with certain exceptions. Metal tanks are also available, but because of their tendency to corrode quickly, they are not normally advised. Septic tanks are available in a variety of shapes, including rectangular, round, and oval, however the design of a septic tank does not normally alter its operation. When selecting a septic tank, the most critical consideration is ensuring that the tank is the appropriate size for your home’s needs.
Concrete Tank Construction
Concrete septic tanks are large and heavy, and their form is commonly rectangular. They’re often built in one of three ways: with a mid-seal, a top-seal, or a monolithic construction. Mid-seal tanks are made up of two sections that are bonded together with mastic sealant to form one unit. A top-seal tank is a one-piece tank with a concrete cover that is attached to the tank. Monolithic cast tanks are constructed in a factory as a single unit, making them more waterproof than other forms of concrete tanks, but they are also more expensive than other types of concrete tanks.
Fiberglass and Plastic Tanks
In circular or capsule-like designs, fiberglass and plastic tanks have a nearly impenetrable waterproof seal and are therefore ideal for use in the marine environment.
The cost of these tanks is more than that of concrete units, but because they are manufactured as a continuous piece, there are no seams. They are also lighter and more resistant to impact cracks than concrete tanks.
A Range of Tank Sizes
Septic tank capacities are measured in gallons, and are determined by the quantity of sewage that the tank can contain in total. It is necessary for septic tanks to store at least two days’ worth of sewage from your residence in order for the solids to be adequately separated from the liquids before the liquids are allowed to enter the absorption area. The size of the tank is determined by the number of bedrooms in your home. Standard tank sizes are generally 1,000, 1,250, and 1,500 gallons, and they are sufficient for the majority of residences in the United States.
A four-bedroom home requires a tank with a minimum liquid capacity of 1,250 gallons, while a five-bedroom residence requires a tank with a minimum liquid capacity of 1,500 gallons.
Estimating Your Needed Tank Size
The size of the tank is computed using a straightforward formula, while other considerations, such as the soil type, must be taken into consideration. Therefore, it is important to have a professional analyze the site and your property in order to decide the optimal size of tank for your needs and requirements. The minimum size necessary for your home may be estimated by multiplying 150 gallons per bedroom by two, and then multiplying that figure twice more than the amount of time needed to retain the water (48 hours).
Assuming your property has more than six bedrooms, or five bedrooms plus a hot tub, you would multiply 150 times 6, and the resultant figure (900) would be increased by two to give you a minimum liquid capacity of 1,800 gallons.
Septic Tank Size Requirements And All Details You Want To Know It !
It is an underground chamber constructed of concrete, fiberglass, or plastic, through which residential wastewater (sewage) runs for the purpose of basic treatment. Solids and organics are reduced by settling and anaerobic processes, but the treatment efficacy is only modest (this is referred to as “initial treatment”). Septic tank systems are a sort of basic on-site sewage treatment system that may be installed anywhere (OSSF). They may be utilized in locations that are not linked to a sewage system, such as rural regions, and are thus less expensive.

- For a rectangular septic tank, multiply the depth (or “inside” height) in feet times the width times the length of the tank to get the volume.
- For example, how many gallons can be stored in a septic tank that is 4 feet deep, 5 feet broad, and 8 feet long?
- With the conversion factor, 160 cubic feet equals.1337 gallons – or around 1200-gallons in a tank of the same capacity.
Consequently, a second technique to calculate the real size or capacity in gallons of an underground septic tank is to multiply the septic tank volume in cubic feet by a constant, which we round up to 7.5 gallons per cubic foot in this case.

Septic systems are not the sort of system that is “one size fits all.” Even if one size tank may be sufficient for one home, this does not imply that it will be sufficient for all households. Talking with a plumbing and septic tank specialist will be your best bet for ensuring that you purchase the proper size tank for your needs. This article will provide you with the fundamental knowledge you need to get started on your home repair and plumbing projects.
Things to consider
The following factors should be taken into consideration when selecting the amount of septic tank that your property requires; for example,
- The following factors should be taken into consideration when selecting the amount of septic tank your home requires:
Septic tanks are typically available in sizes ranging from 750 gallons to 1,250 gallons in capacity. We need some background information before we can get into the meat of the discussion.
What is a Septic Tank?
Septic tanks are self-contained, subterranean chambers or containers that are meant to retain wastewater generated by a home or other building. Generally speaking, septic systems are composed of two major components: the tank and the drain field. As soon as the wastewater exits your home, it will begin to flow into the holding tank. Solid waste will settle to the bottom of the tank, forming a “sludge” layer on the bottom of the tank. Other liquids, such as oil and grease soap residue, will float to the surface, forming the “scum” layer on the surface.
Eventually, when the tank fills, the effluent drains from the tank and onto the drain field, where it is absorbed by the earth.
Are there Different Types of Septic Tanks?
That’s an excellent question! Yes, several sorts of materials are used to construct your septic tank by the manufacturer. When it comes to placing the tank, it all comes down to personal style, affordability, and maneuverability. Let us have a look at the many sorts of tanks that are most typically encountered:
Concrete Septic Tanks
Designed to endure several decades, these tanks are one of the most robust solutions available for your household plumbing requirements. However, because they are the heaviest of the materials, their upkeep and installation will almost certainly be more expensive. Another thing to keep in mind is that they are prone to cracking, which can result in wastewater spilling into the surrounding ground and potentially polluting drinking water.
Plastic Septic Tanks
These tanks are more resistant to the natural, biological, and chemical processes that will take place in your tank as a result of their construction. They are also more resistant to cracking than other types of concrete. Because they are made of plastic, they are lightweight, which makes them quite simple to install. Unfortunately, if your earth moves or floods, plastic tanks have a tendency to shift and wander around underground. It is possible that your tank will move or possibly rise out of the ground as a result of this.
Fiberglass Septic Tanks
These tanks are more resistant to the natural, biological, and chemical processes that will take place in your tank as a result of their design. Aside from that, they are more durable against cracks. Because they are made of plastic, they are lightweight, which makes them very simple to put together and maintain.
Unfortunately, if your earth moves or floods, plastic tanks have a tendency to slide about underground. It is possible that your tank will shift or possibly rise out of the ground as a result of the earthquake.
Steel Septic Tanks
These tanks are becoming increasingly rare, but it doesn’t rule out the possibility of seeing one in the future. Steel is the least expensive of the materials used in septic tanks, but it does so at the expense of durability. Despite the fact that they are intended to endure between 20 and 25 years, they frequently rust before they have reached their entire lifespan. Now that we’ve covered the essential background material, let’s move on to the actual subject at hand.
What Size Septic Tank Do You Need?
- Home with fewer than 1.500 square feet = 750-gallon tank
- Home with fewer than 2,500 square feet = 1,000-gallon tank
- Home with fewer than 3,500 square feet = 1,250-gallon tank
- Home with fewer than 4,500 square feet = 1,250-gallon tank
- And home with fewer than 5,500 square feet = 1,315-gallon tank
- Home with fewer than 2,500 square feet = 1,315-gallon tank
The following are the minimum requirements: 1-2 bedroom home with less than 1.500 sq. ft.; 3 bedroom home with less than 2,500 sq. ft. = 1,000 gallon tank; 4 bedroom home with less than 3,500 sq. ft. = 1,250 gallon tank; 5 bedroom home with less than 4,500 sq. ft. = 1,250 gallon tank; 6 bedroom home with less than 5,500 sq. ft. = 1,315 gallon tank;
How Big of a Septic Tank Do I Need?
The size and kind of tank required for a new septic system are the two most important considerations to make before beginning the installation process. Private sewage disposal is becoming increasingly popular in the United States, with 33 percent of newly constructed residences choosing for on-site wastewater treatment as part of their construction. Septic tank systems, in conjunction with a soil absorption system, or a drain field, are the least costly way of treating residential wastewater currently available on the market.
- The typical size of a home septic tank is from 750 gallons to 1,250 gallons in capacity.
- The system is made up of two major components: the tank and the drain, often known as the soil absorption field or drain field.
- Oil, grease, and soap residue combine to form the scum layer on the surface of the water.
- With each filling of the tank, the effluent drains out of the tank and into the drain field, where it is absorbed by the earth.
- Septic tanks are commonly utilized in residential construction and can be classified into three categories.
- Polyethylene and fiberglass are one-piece products that are significantly lighter than steel.
- In order to determine whether or not you need a septic tank system, check with your local building department to see what laws and requirements apply to onsite wastewater treatment.
- The square footage of the property, the number of bedrooms, and the number of people who will be living there are all important considerations.
- Septic tanks for one and two bedroom homes that are less than 1,500 square feet and 1,000 gallon septic tanks for three bedroom homes that are less than 2,500 square feet are recommended.
- The figures listed above are only estimates.
- Before acquiring a septic tank system, speak with a professional plumbing contractor who is licensed in your region about the many septic tank alternatives that are available to you.

Concrete Septic Tanks Are Probably The Best Option — Build With a Bang
Concrete Septic Tank with a Capacity of 1000 Gallon When it comes to septic systems, whether you’re in the market for a new system or just need a replacement tank, you’ve arrived to the perfect location. As part of our recent investigation into different types of septic systems that are available for your house, we decided that it would be a good idea to also investigate the many types of septic tanks now available on the market. The following are the three most common types of septic tanks that are easily accessible for installation: When constructed properly and maintained on a regular basis, the majority of concrete septic tanks may endure for up to 40 years.
- Waste flow, home size, square footage, number of bedrooms, number of bathrooms, and a few other factors are taken into consideration in septic tank size recommendations and charts.
- Septic tanks are available in a variety of sizes, and you can even obtain tanks that are smaller than 1000 gallons; however, we recommend that you go with a tank that is at least 1000 square feet in size.
- Consult with a licensed expert before purchasing or installing any equipment if you’re going to install a new septic tank or septic system for the first time.
- ” A few of states are now requiring 1000 gallon tanks as the minimum size requirement.
- The popularity of the concrete septic tank can be attributed to its strength, weight, and longevity.
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
The method by which the concrete septic tank was constructed will have an impact on its long-term function. Support, strength, and structural integrity can be increased by using high-quality concrete, adequate water sealing, and the use of structural steel items such as mesh or rebar. It is important to note that concrete septic tanks are more prone to cracking and leaking than their plastic and fiberglass equivalents when exposed to severely cold temperatures and humidity. Most concrete septic tanks may survive up to 40 years if they are constructed properly and serviced on a regular basis.
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.
