How can I tell the size of my septic tank?
- The only way to know for certain the size of your septic tank is to hire a septic maintenance provider to locate, open, and pump the tank. At that time he or she will be able to tell you its exact size and if it’s in good shape or needs maintenance.
How big should a septic drain field be?
A typical septic drainfield trench is 18 to 30 inches in depth, with a maximum soil cover over the disposal field of 36″; or per the USDA, 2 feet to 5 feet in depth.
What is the dimensions of a septic system?
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. Best practice is to find and measure your septic tank for accurate calculations.
How far should drain field be from septic tank?
Common guidelines require at least 50′ clearance distance between a well and a septic system tank or 150′ between a well and a septic drainfield or leaching bed but you will see that different authorities may recommend different distances. Local soil and rock conditions can make these “rules of thumb” unreliable.
How long should a septic drain field last?
It’s important to consider the life expectancy of a drain-field, too. Under normal conditions and good care, a leach-field will last for 50 years or more. Concrete septic tanks are sturdy and reliable but not indestructible.
How long does it take to fill a 1000 gallon septic tank?
Therefore, it will take about 5 years for one adult to fill 300 gallons of a 1,000-gallon septic tank with sludge and scum. A family of four will fill the 300-gallon storage volume of a 1,000-gallon septic tank in about 1.5 years.
How heavy is a 1000 gallon concrete septic tank?
1000 Gallon Concrete Septic Tank Size & Weight: All concrete tank sizes vary. Some of the most popular 1000 gallon concrete precast tanks are around 5′ 1” X 8′ 2” X 5′ 8” and weigh almost 9,000 lbs.
How big of a drain field do I need?
The size of the drainfield is based on the number of bedrooms and soil characteristics, and is given as square feet. For example, the minimum required for a three bedroom house with a mid range percolation rate of 25 minutes per inch is 750 square feet.
What is a good size septic tank?
The recommendation for home use is a 1000 gallon septic tank as a starting point. The 1000 gallon size tank is a minimum and *can be suitable for a 2 bedroom, 3 bedroom house. Some recommendations say to add an extra 250 gallons of septic tank capacity for each bedroom over 3 bedrooms.
Can a septic tank be too big?
A septic tank that is too big will not run well without the proper volume of wastewater running through it. If your septic tank is too big for your house, there wouldn’t be sufficient collected liquid required to produce the bacteria, which helps break down the solid waste in the septic tank.
How often do you pump a 1000 gallon septic tank?
But here are some general guidelines: Family of 2, 500-gallon tank – pump every 2.5 years. Family of 3, 1000-gallon tank – pump every 4 years. Family of 5, 1000-gallon tank – pump every 2 years.
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.
1) The Specific Septic System Type
There are seven different types of septic tank systems, and the size of the tank required will vary depending on the system you choose. The scope of this article does not allow for a comprehensive discussion of each system type and its associated size requirements. We are referring to traditional gravity-fed anaerobic septic systems in this context when we say “system type.” The anaerobic septic system is the most prevalent type of septic system, and it is the one that most people think of when they imagine a septic tank.
- 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.
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.
This article has demonstrated that septic tank recommendations are extremely diverse and depend on a variety of factors like where you reside, local government rules, subterranean soil type, house size, and the amount of wastewater that your unique home is predicted to produce.
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.

There are a lot of elements that influence the size of any septic system that you may require in your home. The system’s dimensions are determined by the size or capacity of the tank, as well as the type of tank used in it (as mentioned above). Consequently, the size of a septic tank is determined by the square footage of the land. It is dependent on the number of bedrooms in the house as well as the overall number of people that live in the residence. Here are some statistics about the size and dimensions of a septic tank to help you understand them better:
|Type of Tank||Tank Capacity||Tank Length (inches)||Tank Width(inches)||Tank Height(inches)|
|Concrete Septic Tank||1000 Gallon – Heavy Duty||96||78||61|
|1000 Gallon – Low Profile||120||67||57|
|Plastic or Fibreglass Septic Tank||1050 Gallon||126||60||51|
|Steel Septic Tank||1000 Gallon||58||58||96|
Understanding Septic Tank Sizes
A septic tank on any property is the initial point of contact for wastewater that is discharged from a dwelling. This effluent then remains in the septic tank for an extended period of time. Several processes are taking on inside the tank during this time period, which are detailed below. Solids are separated from liquids during this step of the process. Once this is completed, the particulates are filtered out and the remaining water is allowed to run away through the drainage field. The size or dimensions of the septic tank, on the other hand, are critical in order for all of this to occur properly.
Among these considerations are:
- The total number of square feet of the property
- There are several bedrooms in the house. There will be a certain number of individuals that will use the property. The frequency with which guests arrive
- The frequency with which major meetings, parties, or get-togethers are held
When homeowners seek the assistance of professionals, things become much simpler. When installing a septic tank, professionals take into account all factors and guarantee that the tank is the appropriate size and proportions. It should also be mentioned that if there are additional users, the capacity of the tank should be increased by 180 litres for each extra user.
In Case the Septic Tank is Smaller – What Happens?
The tank’s dimensions are determined by the size of the tank. Multiple issues will develop if the septic tank is too small and insufficient in capacity. Because of the volume of wastewater that will be generated on the site, it will be unable to cope. The possibility of all kinds of unpleasant situations arises if the septic tank is smaller than the appropriate size. This can manifest itself in a variety of ways, including offensive and stinky odors, overflowing tanks, and obstructions. The most serious issue that might develop as a result of a tiny tank’s capacity is that the resulting pressure can cause liquids to escape before they have had a chance to be completely filtered out.
This can be a significant issue since the solids will not decompose properly. As a result, they will continue to accumulate in the septic tank. Consequently, there will be issues with blocks and overflows.
CALL 1.855.925.0760 FOR A LOCAL SEPTIC QUOTE
In the same way that a septic tank that is too small can cause multiple difficulties, a septic tank that is too huge can cause several problems. A tank that is too large will not perform properly. The effluent will not be able to pass through it efficiently. For example, if you have an overly big septic tank, there may not be enough liquid accumulation, which might lead to an excessive buildup of germs. Because the processing will not take place organically if this occurs, the solids in the tank will not break down adequately as a result of this.
This will ensure that everyone’s health and full hygiene are protected.
Considering the Features of Your House to Determine the Septic Tank SizeDimensions
The requirements of the family must be taken into consideration first and foremost when a homeowner considers the construction of a septic tank. There are various aspects of a home that must be considered while designing it. When purchasing a home, keep the following in mind:
- More than one dishwasher
- More than one kitchen
- More than one bathroom
- Showers with waterfalls
- Low-flow devices
- A hot tub, a swimming pool, and an indoor spa are available.
All of these items are regarded to be nice elements in any home and should be included. In addition, because of the increased water flow, these luxury features will raise the demand for a septic tank with a greater specified size because of the increased water flow. Because of the increased demand for water, it is possible that the tank may need to be larger.

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
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. Of course, all of this is dependent on the number of people who live in the house as well as the amount of water and waste that will be disposed of through the plumbing system.
For the most accurate assessment of your septic tank needs, you should speak with an experienced and trustworthy sewer business representative.
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.

Septic systems are used for on-site wastewater management, and they are located right outside your home. Perhaps your building project is located outside of a municipal service area, or you just like the notion of conducting wastewater treatment on a private basis. The optimum septic tank size is critical to the efficient operation of any septic system, regardless of the purpose for its installation. The percolation test, also known as a perc or perk test, as well as local codes, will be used to establish the position and quantity of field lines to install.
Do I require a large or small septic tank?
Why Septic Tank Size Matters
It is your septic tank’s job to collect and treat all of the water that exits your home through your toilets, showers, laundry, and kitchen sinks. For as long as 24 hours, the water may be kept in the tank, which also serves as a separation chamber where solids are removed from liquids in the process. When it comes to separating particles from liquids, the retention time is critical. The presence of bacteria in the tank aids in the breakdown of sediments. The size of the tank has an impact on how successfully the system can separate and break down the waste materials.
Although it might seem logical to believe that a larger tank is preferable, a tank that is too large for your water usage can interfere with the formation of germs.
Calculation by Water Usage
There are a variety of formulas that can be used to calculate the size of the septic tank that is required for your property. The most precise and dependable method is to measure water consumption. The size of the septic tank that is required is determined by the amount of water that will be handled and then dispersed into the field lines of the property.
It should be noted that the minimum capacity tank permitted in many regions of the nation is 1,000 gallons. The following is a recommended tank size based on the total amount of water used by your household.
- 900 gallon tank for up to 500 gallons per day
- 1,200 gallon tank for up to 700 gallons per day
- 1,500 gallon tank for up to 900 gallons per day
- Tank holds up to 1,240 gallons per day
- Tank capacity is 1,900 gallon.
Calculations By House Size
The number of bedrooms in your home, as well as the square footage of your home, are less precise guides for determining the size of your tank. The maximum number of bedrooms that may be accommodated by a 1,000 gallon septic tank is two. It’s difficult to say due to the fact that water consumption varies depending on your situation. These estimates are based on the assumption that all bedrooms will be occupied, and the anticipated water consumption is based on this assumption. It is impossible to do these calculations if you live alone in a three-bedroom house.
The suggested tank sizes are listed below, according to the number of bedrooms in the house.
- Three bedrooms under 2,500 square feet: 1,000 gallon tank
- Four bedrooms under 3,500 square feet: 1,200 gallon tank
- And five or six bedrooms under 5,500 square feet: 1,500 gallon tank
- One or two bedrooms under 1,500 square feet: 750 gallon tank
- Three bedrooms under 2,500 square feet: 1,000 gallon tank
Similarly to the cost of any other commodities or services, the price might vary significantly based on where you reside and the current market circumstances. Let’s pretend you’re going to install a concrete septic tank for the sake of planning your project. These are by far the most prevalent, and they have a somewhat lengthy life span. The cost of a typical 1,000-gallon septic tank is between $500 and $700 dollars. The cost of upgrading to a 1,250-gallon tank will be at least $100 more. After three to five years, depending on the size of the tank, you could anticipate to have a cleaning job to do.
If you’re debating between two different tank sizes, knowing your financial constraints might assist you make your ultimate selection.
Although your contractor should be able to assist you in sizing your tank, understanding how to roughly determine your size requirements will help you anticipate how much you’ll need and how much you’ll spend on your tank.
Concrete Septic Tanks Are Probably The Best Option — Build With a Bang
Concrete Septic Tank with a Capacity of 1000 Gallon When it comes to septic systems, whether you’re in the market for a new system or just need a replacement tank, you’ve arrived to the perfect location. As part of our recent investigation into different types of septic systems that are available for your house, we decided that it would be a good idea to also investigate the many types of septic tanks now available on the market. The following are the three most common types of septic tanks that are easily accessible for installation: When constructed properly and maintained on a regular basis, the majority of concrete septic tanks may endure for up to 40 years.
- Waste flow, home size, square footage, number of bedrooms, number of bathrooms, and a few other factors are taken into consideration in septic tank size recommendations and charts.
- Septic tanks are available in a variety of sizes, and you can even obtain tanks that are smaller than 1000 gallons; however, we recommend that you go with a tank that is at least 1000 square feet in size.
- Consult with a licensed expert before purchasing or installing any equipment if you’re going to install a new septic tank or septic system for the first time.
- ” A few of states are now requiring 1000 gallon tanks as the minimum size requirement.
The popularity of the concrete septic tank can be attributed to its strength, weight, and longevity. For more precise information on durability, concrete septic tanks that are correctly constructed have a lesser probability of breaking, cracking, or floating.
Check out these 6 septic systems available for your home.
Nowadays, most concrete septic tanks are sold with a two compartment design, as opposed to the earlier style one compartment tank that was more common previously. Two compartment tanks tend to perform a better job of filtering and separating waste than one compartment tanks, which is why septic experts advocate them over a single compartment tank. All compartments are constructed with access for cleaning and pumping, regardless of the number of compartments in the system. Because it can readily handle most 0-3 bedroom dwellings, a 1000 gallon septic tank is the standard size for domestic applications.
Heavy Duty Options
Many tanks are also available in “high duty” configurations, which generally have a reinforced top and bottom. Purchasing the heavy-duty version may be a wise decision in the case that a vehicle, agricultural equipment, or other large piece of heavy machinery passes over the tank area.
Because of the size and weight of concrete septic tanks, they must be installed by a qualified specialist. These tanks are constructed of the hardest materials available, and while they are extremely durable, their installation necessitates the use of enormous, heavy machinery. If the intended or present site of your concrete septic tank does not allow for heavy machinery access, you may want to investigate a fiberglass or plastic (polyethylene) tank. Due to the fact that the majority of concrete tanks are precast, their sizes, weights, and dimensions are all different.
Lifespan and Durability
The method by which the concrete septic tank was constructed will have an impact on its long-term function. High-quality concrete, adequate water sealing, and the use of structural steel goods such as mesh and rebar will provide additional support, strength, and structural integrity to the structure. Keep in mind that concrete septic tanks are more prone to cracking and leaking than their plastic and fiberglass equivalents when exposed to exceptionally cold temperatures and pressures. Most concrete septic tanks have a lifespan of up to 40 years if they are constructed properly and serviced on a regular basis.
1000 Gallon Concrete Septic Tank
Septic tanks of 1000 gallon capacity or larger are the most typical size for household usage, as they can readily fit most 0-3 bedroom dwellings. Size Weight: The weight of each concrete tank is different. Some of the most common 1000 gallon concrete precast tanks are around 5′ 1″ X 8′ 2″ X 5′ 8″ in size and weigh almost 9,000 lbs. Others are approximately 5′ 1″ X 8′ 2″ X 5′ 8″ in size and weigh almost 9,000 lbs. Here are some examples of Jensen Precast projects completed in various cities around the United States.
1250 Gallon Concrete Septic Tank
Generally speaking, a 1250 gallon tank is a good choice for mid-size homes with 3-4 bedrooms. Size and weight: The sizes and weights of all concrete tanks are different. 1250 gallon concrete precast tanks are typically 5′ 9″ x 8′ 6″ x 5’8″ in size, with some of the more common models being 5′ 9″ x 8′ 6″ and others measuring 5′ 8″. The typical weight of a 1250 gallon concrete tank is 11,000 lbs, however this might vary depending on the distributor. Approximately 11 1/2 feet in depth, however this varies according on the distributor, state, and local statutes.
In addition, many of these bigger tank sizes are so massive that rebar and wire mesh are required within the walls and between layers to provide additional strength, stability, and durability.
1500 Gallon Concrete Septic Tank
Generally speaking, a 1500-gallon tank is the most popular size for large homes with five or more bedrooms. Size and weight: The sizes and weights of all concrete tanks are different. The dimensions of some of the most common 1500 gallon concrete precast tanks are around 6′ x 10′ 9″ x 5′ 5″ in length and width. The typical weight of a 1500 gallon concrete tank is 12,000 lbs, which is rather heavy. Approximately 12 feet in depth, however this varies according on the distributor, state, and local statutes.
When installing a septic tank, an inlet baffle should be put on the inlet part closest to the point at which the sewer tank joins from the house structure to the tank. Due to the fact that it prevents scum and oils from blocking the entrance pipe, the inlet baffle is critical to the overall health and effectiveness of the septic system. The intake baffle is a bottle neck that is especially designed to do the following:
- In order to prevent the breakdown process from being disrupted, it is necessary to slow the effluent entering the septic tank. A fast rate of inflow of effluent might cause problems by mistakenly combining the settled solid waste with oils, scum, and effluent. Make sure no sewage gases are allowed to enter the sewer line. These gases have the potential to infiltrate back into a home or structure, generating a foul odor.
Every septic tank should be equipped with an exit baffle that is connected to the discharge line. The outlet baffle functions as a bottle neck in the same way as the inlet baffle, but in the opposite direction. It is meant to:
- Preserving the septic tank by keeping scum, oils, and solid waste contained inside
- It is necessary to prevent the discharge of waste items other than wastewater into the output pipe, drain field, and leach field.
All effluent from the septic tank must be clear of solid waste before it may be discharged. Other than that, the solids and oils will pollute the drain field/leach field and result in backups and pollutants entering the surrounding environment. Ensure that your baffles are correctly built and that they are not in need of repair by consulting with a licensed septic technician before doing anything else. Septic tanks made of fiberglass or polyethylene (polyethelyene) are also a suitable option, especially if your location has specialized environmental requirements.
In contrast to concrete septic tanks, which normally need a vehicle equipped with a crane and boom, fiberglass and polyethylene septic tanks are quite simple to transport. Therefore, fiberglass and plastic tanks are frequently employed in places where concrete septic tank delivery vehicles are unable to reach the tanks. The majority of fiberglass and plastic septic tanks weigh roughly 300 pounds or more, however concrete septic tanks can weigh up to 20-30 times as much.
If you’re seeking for a less expensive alternative to concrete, fiberglass and polyethylene (polyethylene) are excellent choices. The majority of fiberglass and plastic septic tanks are thousands of dollars less expensive than concrete septic systems.
When compared to a concrete septic tank, both plastic and fiberglass septic tanks have a lower likelihood of breaking. Furthermore, because fiberglass and plastic are nonporous materials, there is typically no problem with tree or bush roots growing into the tank and generating leaks as a result of root damage. Having said that, due to the tank’s smaller profile and lighter material composition, caution must be used during installation because heavy gear might easily harm it. Tanks made of fiberglass or plastic can be destroyed in the same way as concrete tanks can if too much weight is placed on the surface above them.
Despite the fact that plastic and fiberglass tanks are quite resilient, they can nonetheless leak under specific circumstances.
As a result, it’s important to contact with a septic installation specialist before making a final decision on a certain material. The size of the lot, the position of the tank, the amount of ground water, and the weather can all influence the selection.
Plastic and fiberglass have a number of advantages, but they can also be troublesome. Yes, the lightweight character of these materials makes them perfect for installation, but same lightweight nature also results in a high level of buoyancy in the final product. It is possible that during a storm, a plastic or fiberglass tank can get dislodged from its couplings, causing considerable damage to the septic system and the homeowner’s property, with repair costs in the hundreds of dollars. A simple solution is to place a concrete slab on top of the tank to help weigh it down.
If you reside in an area with a high groundwater table, consult with a specialist to ensure that the higher water table will not cause harm to your fiberglass or plastic tank.
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.

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.
- Septic tanks made of fiberglass
- Septic tanks made of plastic
- Septic tanks made of concrete
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.
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.
- A septic tank with a capacity of 1,900 gallons will handle less than 1,240 gallons per day
- A septic tank with a capacity of 1,500 gallons will handle less than 900 gallons per day. A septic tank with a capacity of 1,200 gallons is required for less than 700 gallons per day
- A septic tank with a capacity of 900 gallons is required for less than 500 gallons per day.
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. Please contact us to determine the optimal septic system size for your North Atlanta, GA house.
