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.

  1. The following systems are available: conventional, gravity-fed, anaerobic systems
  2. Above-ground septic systems
  3. Pressure systems
  4. Anaerobic systems
  5. Mound systems
  6. Recirculating sand or gravel filters systems
  7. 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:

  1. 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.

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.

The proper size of your septic tank is critical to the optimal operation of your private sewage disposal system. 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.

  • 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.

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, on the other hand, your property has more than five occupants, you will require a larger septic tank in order to manage your wastewater more effectively and hygienically.When determining what size septic tank I need, it is important to remember that septic tank sizes determine the overall efficiency of your septic system.Septic tank sizes are determined by the amount of wastewater that can be handled by the tank.

When the holding capacity of your home’s septic tank is exceeded, wastewater can back up into your home, causing blockages, floods, and putting you and your family in danger.

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 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

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.

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.

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.

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.

WAC 246-272A-0232:

Septic tanks must meet the following requirements:(1) have at least two compartments, with the first compartment liquid volume equal to one-half to two-thirds of the total liquid volume; and(2) have at least two compartments with the first compartment liquid volume equal to one-half to two-thirds of the total liquid volume. It is possible to meet this specification with a single tank with two compartments or by connecting two single compartment tanks together in sequence. (2) Have the following minimum liquid volume requirements in place: (a) For the purpose of a single-family house Required Minimum Liquid Volumes of Septic Tanks, as shown in Table VII: TABLE VII: Minimum Liquid Volumes of Septic Tanks Required by Law

Number of Bedrooms Required MinimumLiquid Tank Volume in Gallons
≤3 900
4 1000
Each additional bedroom 250

Two hundred fifty gallons per bedroom for any residential source other than a single-family residence, with a minimum of one thousand gallons for any nonresidential source; three times the design flow for any nonresidential source; and three times the design flow for any residential source other than a single-family residence

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

Aside from the number of pumping chambers in a septic tank, the number of pumping chambers in a septic tank is another factor that may be used to calculate the size of the septic tank in some jurisdictions. For example, a septic tank with an incorporated lift station pumping chamber must have an extra capacity of 250 gallons in addition to the standard capacity. It is also necessary to take into consideration the local weather conditions in the location where the septic tank will be constructed.

In order to accommodate this, the septic tanks in these areas need be larger.

Legal requirements– before building and installing a septic system, it is usually a good idea to check to see if there are any legal standards that must be followed in the process.

In the event that you want to make any improvements to your house, such as the installation of another bedroom, you may want to consider installing a larger septic tank to accommodate the additional space.

What Septic Tank Size Do You Need?

You are in the process of designing your ideal home. The number of bedrooms has been determined. The floor plan has been finalized. The decision has been made to install an on-site septic system. The only issue left is: what size septic tank do I require in the end?

Septic Tank Size Matters

We’ve all heard the expression, but it’s especially true when it comes to determining the appropriate septic tank size for your house, company, or land. A tank that is too tiny indicates that there is not enough time for waste to be retained in the tank, resulting in less than optimum settlements of waste material. What exactly does this imply? The bacteria that are trying to break down waste materials don’t have enough time to do their work before the rubbish is pushed out of the way to make way for more waste.

A tank that is too large can hinder the growth of bacteria and the generation of heat, both of which are necessary for your system to operate properly and ideally. The bottom line when it comes to septic tank installation is that size does important.

What Factors Matter?

There are a variety of elements that go into estimating your water use and the amount of septic tank that is required. Although each state and county has their own minimal regulations, a good rule of thumb is that your daily sewage flow should not exceed 60 percent of your tank’s capacity on a regular basis. Keeping this in mind, some additional considerations are as follows: The number of people that live in the house and the size of the house. The amount of bedrooms and square footage of your property as well as the number of residents are all important considerations.

  1. Also bear in mind that this covers the number of visitors you receive and the regularity with which they arrive.
  2. Usage.
  3. What are the appliances that you use on a regular basis?
  4. How many showers are there?
  5. Obtaining an accurate assessment of your water use before installing your on-site septic system is critical when it comes to water utilization.

The Goldilocks Size

The following is a general overview that industry standards use to determine tank sizes for households: According to the Florida Department of Health, the following tank sizes are recommended for residential dwellings based on daily capacity requirements.

  • A minimum of 900 Gallons Tank is required for a one-bedroom home less than 750 square feet
  • A minimum of 900 Gallons Tank is required for two-bedroom homes less than 1,200 square feet
  • A minimum of 1,050 Gallons Tank is required for three-bedroom homes less than 2,250 square feet
  • A minimum of 1,200 Gallons Tank is required for four-bedroom homes less than 3,300 square feet
  • And for each additional occupant, a minimum of 50 Gallons Tank is required.

It is crucial to note that these are only estimations at this time. The need of consulting with an on-site septic system specialist before deciding the appropriate tank size for your house or company cannot be overstated. So, which septic tank size is most appropriate for your residence? You know, not too huge, not too tiny, but just the proper amount of everything? This is the explanation and remedy provided by Chris Bryan, Licensed Septic Contractor and Owner of Advanced Septic Services of Clermont: “The size of a septic tank is determined by the estimated gallons per day of flow.” This is computed based on the number of bedrooms in the house and the quantity of living square feet in the house.

What Size Septic Tank Do I Need? – Drain Doctor Clackamas

The use of septic tanks allows for on-site wastewater management on the property rather than transferring effluent to a municipal treatment plant for treatment. If you’re building outside of a municipality, you’ll need a septic system installed. The septic tank is a self-contained storage tank for wastewater, in which natural bacteria breakdown human waste as a result of the presence of these bacteria. Whether you’re building a home or replacing an existing septic system, you might be thinking, “What size septic system do I need?” In order to answer this question, you must first determine how many bedrooms there are in the house and what size system the Clackamas County Soil’s Department has determined you must install.

Bedrooms in the Home Set Minimum Tank Size

The size of a septic tank is determined by the amount of liquid waste it must treat. The minimum tank size for a residential property is determined by the number of bedrooms in the residence, according to the Clackamas County Soils Department. When it comes to a home with only four bedrooms or less, the septic tank needs to be at least 1,000 gallons in capacity. A tank with a capacity of 1,500 gallons is required for a larger residence. Nevertheless, according to the standards of the Clackamas County soils department, a greater capacity tank may be necessary for “special or unique waste characteristics, such as flow patterns, volumes, waste strength, or facility operation.” If the property is expected to generate more wastewater than typical, you should consider upgrading to a bigger tank.

How to Calculate Septic Tank Size

Riverside, California 92504-17333 Van Buren Boulevard Call us right now at (951) 780-5922. Every septic system owner should be familiar with the process of calculating the size of their septic tank so that they can plan for how often their tank will need to be pumped to maintain it working at top performance. It is significantly less expensive to do even a little amount of preventative maintenance than it is to install a whole new system. As a result, it is critical to be aware of when your septic tank will require pumping in order to avoid missing a maintenance appointment.

Eventually, if the accumulation of particles in the tank gets too great and sediments begin to flow into the drainfield, the system may become clogged and overburdened to the point where a new drainfield will be required. As a result, determine the size of your septic tank before it is too late.

Types of Septic Tanks

Septic tanks are commonly utilized in residential construction and can be classified into three categories.

  • Septic tanks made of concrete
  • Septic tanks made of polyethylene/plastic
  • Septic tanks made of fiberglass

Construction of concrete septic tanks is the most popular, but because of their weight, they must be installed with heavy gear. Polyethylene and fiberglass are one-piece products that are significantly lighter than steel. This makes them particularly well suited for isolated and difficult-to-reach locations. 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.

Why Choosing the Right Septic Tank Size Matters

sewage can back up into your home if a septic tank is installed that is too small and does not have enough holding capacity. When installing a septic tank, it is critical that you determine the proper size. The majority of towns require even the smallest septic tanks to carry a minimum of 1,000 gallons of wastewater. As the number of bedrooms, occupants, bathrooms, and fixtures that will be serviced by the septic system rises, the needed capacity for the system increases accordingly.

How Much Water Do You Use?

The failure of an undersized septic tank to hold its holding capacity can result in the backup of sewage into your home, thus it is imperative that you determine the exact size when installing a septic tank. Septic tanks of any size are required to store around 1,000 gallons in most towns, even the smallest ones. Based on the number of bedrooms and inhabitants, as well as bathrooms and fixtures that the septic system is expected to service, the needed capacity grows from that point on.

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. What is the maximum number of bedrooms you can have with a 1,000 gallon septic tank? It is tough 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

Septic Tank Size Affects Pumping Schedule

The size of your septic tank is important because it determines how frequently it has to be pumped in order to stay working at top performance. As a general rule, we recommend that you pump your septic tank every three to five years; however, the smaller the tank, the more frequently it must be pumped. Tanks that are not maintained properly over an extended period of time are more likely to get clogged or fail, necessitating costly repairs or replacement.

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. It is not recommended to put trees or anything else with deep roots along the bed of the drain field since the roots of these plants frequently clog the pipes. 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. Make your septic tank lid as accessible as possible so that maintenance and inspection may be performed without difficulty. To aid with evaporation and erosion prevention, plant grass in the area.

How many bathrooms can you have in a 1000 gallon septic tank?

Do I require a large or small septic tank?

Bedrooms Home Square Footage TankCapacity
1 or 2 Less than 1,500 750
3 Less than 2,500 1,000
4 Less than 3,500 1,250
5 Less than 4,500 1,250
Septic Tank in Gallons Size Based on Number of Bedrooms
Number of bedrooms Minimum Septic Tank Capacity (Gallons) Minimum Septic Tank Liquid Surface Area (sq.ft.)
1, 2, or 3 bedrooms 1,000 gallons 27 sq.ft.
4 bedrooms 1,200 gallons 34 sq.ft.
5 bedrooms 1,500 gallons 40 sq.ft.

Also, do you know how much water a septic system can manage in a single day? In the usual day, a person consumes between 60 and 70 gallons of water. When designing tanks, we make the premise that there are two people in each bedroom. As a result, an aseptic tank can normally manage around 120 gallon per bedroom every day. Taking everything into consideration, how many bedrooms can a 1500 gallon septic tank accommodate? Homes with 1-2 bedrooms and fewer than 1,500 square feet require a 750 gallon tank.

Homes with four bedrooms and fewer than 3,500 square feet require a tank with a capacity of 1,250 gallons.

The size of the septic tank should be determined mostly by the square footage of the house and the number of people who will be living there.

A 1000 gallontank will most likely be required for a typical 3-bedroom home that is smaller than 2500 square feet in size.

How Big of a Septic Tank Do I Need?

If you’re constructing a home, a septic tank is unquestionably one of the most significant considerations you should take into consideration. Septic tanks are used to dispose of wastewater outside the residence. The size of the septic tank is one of the most important elements to consider when determining whether or not it will function properly. In this article, we’ll go over why septic tank sizes are important and how to establish the appropriate tank size for your property based on your requirements.

Why Septic Tanks’ Sizes Matter?

To understand why size matters in this situation, we must first clarify what septic tanks are used for. Septic tanks are the initial stage of a septic system’s journey through the earth. They are the initial point of contact for all of the water in your home. The wastewater might originate from anywhere: the laundry, showers, toilets, or even the kitchen. Liquids are separated from solids in this facility. After the solids have been broken down, everything runs into the drainage system, which is the other component of the septic tank system.

  1. Retentions occur as a result of the bacteria present in the tank.
  2. Now, if the tank is insufficiently large.
  3. Because more wastewater is being pumped into the system, the waste is being driven out into the drainage system before the bacteria have finished breaking it down.
  4. However, if the tank is too large, there will not be enough heat to support the growth of bacteria.

A lack of microorganisms results in a lack of breakdown of waste materials. The same problems would arise as a result of this. Check out this page for helpful hints on how to take the best possible care of your septic system.

How to Decide What Size Is Best?

Before we get into the specifics of how much of a tank you require, we’d want to point out something very crucial.

How to Calculate a Tank’s Capacity in Gallons?

If the tank is rectangular in shape, the dimensions are as follows: Length x Width x Depth in feet x 7.5 = gallons If the tank is circular, the cubic capacity is equal to 3.14 x the radius squared x the depth (all in feet). Cubic capacity multiplied by 7.5 equals gallon capacity. There are various elements that influence the size of the septic tank that should be installed. They’re right here!

1. Water Usage

You may decide the size of the tank you require based on the amount of water used by your home. This is often considered to be the most efficient component to consider, because the size of the tank required is directly proportional to the amount of water it can hold in its capacity. In order to ensure compliance with local regulations, learn about the minimum tank size necessary in your area. The restrictions differ from place to location, but in most cases, a minimum capacity of 1000 gallons is permitted.

For example, if your daily water use is 500 gallons, your septic tank should have a capacity of 900 gallons.

2. Number of People Residing in the House

Your water use as a household might help you calculate the size of tank you require. Due to the fact that the size of the tank required is directly proportional to the amount of water it can hold, this is typically considered the most efficient component to consider. In order to ensure compliance with local regulations, learn the minimum tank size necessary in your area of the nation. They vary from location to location, but in most cases, a minimum capacity of 1000 gallons is acceptable. It is recommended that the tank be at least 400 gallons larger than the amount of water that will be stored in it.

Our second element is the typical daily water use of a person, which is between 80 and 100 gallons.

3. Size of the House

In this case, you may argue that the size of the home or the number of bedrooms it contains doesn’t important or that using such parameters would be misleading. Because there are so many circumstances in which there are vacant rooms, it’s possible that you’ll think this way. This would be the incorrect way of thinking about it, because septic tanks typically have a lifespan of 50-70 years, depending on the manufacturer. During those years, other families may be interested in purchasing or renting the house.

There are two methods to go about calculating the value.

Using the Number of Bedrooms in the House

Regulations such as this one determine the average use based on the assumption of two persons per bedroom. To be on the safe side, follow this formula: there are two persons in every bedroom, and each person requires 100 gallons of water.

Then, add 400 gallons to the mix. This should provide you with a good idea of how large your tank should be in terms of volume. For example, if you have three bedrooms and six people, 600 + 400 equals a 1100 gallon tank.

Using Square Feet

You might double the square footage of your home by two, or you could just apply the usual estimating method, which goes as follows: If your home is smaller than 1,500 square feet, you’ll need a 750-gallon tank. If your home is smaller than 2,500 square feet, you will need a 1,000 gallon tank. If your home is smaller than 3,500 square feet, you will need a 1,250 gallon tank. If your home is smaller than 4,500 square feet, you will need a 1,250 gallon tank. If your home is smaller than 5,500 square feet, you’ll need a 1,315 gallon tank.

Wrapping Up

You now see how critical the size of the septic tank is to ensuring that the whole sewage system functions well and does not cause you any immediate or cumulative problems in the future. In this tutorial, we examined the most significant considerations to bear in mind, which include the amount of water used, the size of your home, the number of people who live there, and the number of bedrooms in the home. Make sure to do these calculations ahead of time to avoid any complications in the future.
