What Size Septic Tank Do I Need?
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. This can have an impact on the tank’s efficiency.
Calculation by Water Usage
There are a variety of calculations that can be used to determine the size of the septic tank that is required for your home. The most accurate 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 size tank permitted in many parts of the country 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.
- The number of bedrooms in your home or the square footage of your home might be used as a less precise reference for determining the size of your tank. Which number of bedrooms can you fit into a 1,000-gallon septic tank? Because water consumption varies depending on your situation, it’s difficult to state for sure. Based on the assumption that all bedrooms would be occupied, the anticipated water consumption is calculated. These estimates will be incorrect if you live alone in a three-bedroom house. These estimates are necessary since a new owner may choose to occupy all of the bedrooms, and the tank must be large enough to accommodate the additional weight. Based on the amount of bedrooms in your home, below are the suggested tank sizes.
Estimated Cost
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.

Learn why the size of your septic tank is important in the first place, how to determine what size septic tank you need for your home, and how much it will cost to build a septic system in your home by continuing to read.
Why Septic Tank Size Matters?
Everything that comes out of your home, including water from your shower, toilets, kitchen, and laundry, ends up in your septic tank. So, in other words, the first destination for all of your wastewater is your septic system. It can linger there up to 24 hours, during which the solid waste is separated from the liquids. This retention duration is critical in ensuring that solids are successfully separated from liquids throughout the separation process. In the tank, bacteria and enzymes work together to remove solid waste and break it down into liquids and gasses, which are then released into the environment.
- The wastewater is flushed out early if the tank is too small, and the solid waste does not have a time to settle before the wastewater is flushed out.
- The only way it can accomplish this is by draining out the wastewater that is now contained inside it – regardless of whether or not it has been adequately treated.
- If the tank is too large for the volume of wastewater you create, it will interfere with the formation of beneficial microorganisms.
- See the 1000 Gallon Septic Tank Dimensions and the Different Septic Tank Types.
- For the most part, the size of the septic tank should be adequate for your requirements — neither too tiny nor too large.
What are the Different Methods of Calculating the Septic Tank Size for Your Home?
It is your septic tank that collects and treats all of the water that exits your home through your shower, toilet, sink, kitchen, and laundry. So, in other words, the first destination for all of your wastewater is your septic system. It can linger there up to 24 hours, during which the solid waste is separated from the liquid waste. In order to guarantee that solids are adequately separated from liquids, it is necessary to maintain a specific retention time. In the tank, bacteria and enzymes are responsible for separating solid waste from liquid waste and breaking it down into liquids and gases.
The wastewater is flushed out early if the tank is too small, and the solid waste does not have time to settle before the wastewater is flushed out.
Regardless of whether the wastewater has been adequately treated or not, the only way it can do this is by flushing away the wastewater that is now present inside the tank.
Using a tank that is too large for the amount of wastewater you create might cause problems with the formation of bacteria.

Some municipal authorities utilize the number of bedrooms or the square footage of a residence instead of the projected wastewater flow to aid homeowners in selecting the appropriate septic system size for their home or business. The question is, what are the appropriate septic tank sizes for a house dependent on the number of bedrooms it has? Here’s a table that you may use as a guideline when writing.
| No. of Bedrooms | House Square Footage | Tank Capacity |
| 1 or 2 | Less than 1,500 | 750 gallons |
| 3 | Less than 2,500 | 1,000 gallons |
| 4 | Less than 3,500 | 1,250 gallons |
| 5 | Less than 4,500 | 1,250 gallons |
| 6 | Less than 5,500 | 1,315 gallons |
Be aware that these figures are based on the assumption that all of the bedrooms in the house will be used at the same time. If you live alone in a three-bedroom house, these figures may not apply to you in all situations. Most of the time, the size of the septic system that is required is determined by the projected daily water use of a family. This is because it is the most accurate method of determining the size of a septic tank, as the most important concern when installing a new tank is that it must be able to manage the quantity of water that will be directed at it throughout its operation.
Having said that, in many parts of the United States, the minimum size for an aseptic tank is set at 1,000 gallons or less.
| Daily Average Wastewater Flow | Minimum Septic Tank Size |
| 0-500 gallons per day | 900 gallons |
| 601-700 gallons per day | 1200 gallons |
| 801-900 gallons per day | 1500 gallons |
| 1001-1240 gallons per day | 1900 gallons |
| 2001-2500 gallons per day | 3200 gallons |
| 4501-5000 gallons per day | 5800 gallons |
When establishing a septic system, you may need to consider another aspect in addition to the number of bedrooms and the average daily wastewater flow. This consideration is the temperature of the surrounding environment. It is particularly recommended in some municipal septic rules that septic system sizes be assessed in light of the local climate in some instances. During the winter months in severe cold areas such as Alaska, the pace at which bacteria break down the solid waste in the tank is slowed by the frigid temperatures.
In contrast, if you live in an area where the environment is extremely hot or warm, you may be able to get away with a lower septic tank capacity.
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. They can assist you in planning the intricacies of your septic system, including which sort of septic system will be most beneficial to you.
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
Vehicles should not be allowed on or near the drainfield. Planting trees or anything else with deep roots near the drain field’s bed is not recommended. Clogged pipes are frequently caused by the roots of plants; Downspouts and sump pumps should not be drained into the septic system; and If you want to tamper with or change natural drainage characteristics, do so after researching and evaluating the impact on the drain field. Do not construct extensions on top of the drain field or cover it with concrete, asphalt, or other similar materials.
Easy maintenance and inspection are made possible as a result of this; To aid with evaporation and erosion prevention, plant grass in the soil.
- 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.

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
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.
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
The septic tank size recommendations offered here are merely that: suggestions. They are built on a foundation of information gathered from government and academic sources. The actual size of the septic tank you require will vary depending on the factors discussed in this article. There is no “one-size-fits-all” solution when it comes to determining the appropriate septic tank size for your property. There is a great deal of variation depending on where you reside. With addition to providing a basic insight into the septic tank and system size that may be most suited to your application, the providedMinimum Septic Tank Capacity Tablecan also assist in cost estimations.
Before beginning any septic tank installation project, check and double-check with the state, city, or local county’s agency that is in charge of septic tanks, soil testing, and permissions.
If you’re searching for a chart of tank sizes, have a look at our page on the many sizes and quantities of septic tanks available.
They are available in both single chamber and double chamber designs. Consider reading this article from Texas A M University, which provides an overview of onsite wastewater treatment systems, for further information on traditional septic systems.
Do you need a bigger septic tank size?
When constructing, purchasing, or renting a home, it is critical to understand the appropriate septic tank size for the land being considered. A house with the incorrect septic tank size could put you in a difficult situation if the tank becomes overflowing prematurely. The government may order you to replace your septic tank, which may cost you thousands of dollars if it fails completely. To avoid this, make certain that the septic tank is the appropriate size from the beginning.
Using the number of bedrooms to determine septic tank size
The number of beds on a property must be taken into consideration when deciding the size of the septic tank to be installed on the land, according to the legislation. This is mostly due to the fact that the number of bedrooms will provide a clear indication of the maximum number of people who will be able to occupy the property. Because the septic tank will be the initial point of contact for all of the wastewater from the residence, it is important to choose the appropriate size. The effluent should be allowed to sit in the tank for at least 24 hours before it is discharged into the drainage system.
If this is not done, the solids will flow out of the tank and into the drain field, resulting in a blockage of the drain field and the tank.
| Number of bedrooms | Minimum capacity in gallons |
| 1 – 3 | 750 |
| 4 | 850 |
| 5 – 6 | 1,050 – 1,500 |
Using water usage to determine the septic tank size
Even after determining the most appropriate septic tank size based on the number of bedrooms in the house, you may choose to take additional aspects into consideration. The water usage rates of two identically sized dwellings might be drastically different. For example, if you plan to use a garburator, the amount of wastewater that will be discharged into the septic tank will increase. It is possible that you may need to account for high-volume fixtures. The flow rates of some of the most regularly used plumbing fittings, as well as the predicted demand during peak periods, are included in the table below.
| USE | FLOW RATE (GALLONS PER MINUTE) | TOTAL USE (GALLONS) |
| Bathroom sink | 2 | 1-2 |
| Backwash filters | 10 | 100-200 /backwash cycle |
| Garbage disposer | 3 | 4-6 per day |
| Dishwasher | 2 | 5/load |
| Kitchen sink | 3 | 2-4/use |
| Shower/ tub | 5 | 25-60/use |
| Toilet flush (pre-1992 design) | 3 | 4-7/use |
| Toilet flush (high-efficiency design) | 3 | 1.28/use |
| Washing machine | 5 | 15-30/load |
Others factors that determine the size of the septic tank
Other aspects should be taken into consideration even if the number of bedrooms is used to calculate the most appropriate size for the septic tank. The water usage rates of two identically sized homes might be vastly different! Consider that if you want to use a garburator, the amount of wastewater that will enter the septic tank will be more than usual. Furthermore, high-volume fixtures may need to be taken into account. The flow rates of some of the most regularly used plumbing fittings, as well as the predicted demand during peak periods, are shown in the table below.
Conclusion
Choosing the proper septic tank size will save you a lot of headaches in the long run. As a starting point, you will not be in contravention of any legal requirements that are in effect in your country.
Additionally, by constructing the proper septic tank for your property, you can ensure that your septic system will operate properly and without interruptions throughout the year. It will also aid in the extension of the life of your septic system.
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.

a little about the author: The Andrew J. Foss, Inc. precast concrete firm was founded by my father in 1963 when he was just 19 years old. My precast education began at a very young age for myself. Everything I know about producing high-quality precast concrete goods, from septic tanks to concrete headwalls, was passed down to me by him. He also taught me that in order to be successful in business, you must provide a superior product and treat your customers the way you would like to be treated yourself.
Together with my brother Matthew, I am now the sole owner of our family-owned precast concrete firm, and we have used all we’ve learned from our father to launch the next generation of our family-owned precast concrete company.
