What is the average size of a septic tank?
- An average-sized septic tank has a capacity of anywhere from 1,000 to 1,500 gallons (3,785 to 5,678 liters), though for high-impact areas large tanks with 5,000 to 10,000 gallon (18,927 to 37,854 liters) capacities exist.
How big is a normal septic tank?
Common residential septic tanks range in size from 750 gallons to 1,250 gallons. A septic tank is a self-contained unit designed to hold residential wastewater. The system is comprised of two main components: the tank and the drain, or soil absorption field.
How many gallons does a typical septic tank hold?
Most residential tanks have a capacity ranging from 750 gallons to 1,250 gallons and the average person uses 60 gallons to 70 gallons of water a day.
How often does a 1000 gallon septic tank need to be pumped?
For example, a 1,000 gallon septic tank, which is used by two people, should be pumped every 5.9 years. If there are eight people using a 1,000-gallon septic tank, it should be pumped every year.
How do I figure out the size of my septic tank?
One way to find out the size of your septic tank is through records kept from when the tank was installed. These records could be with the previous owner of your home. Another way to identify the tank size is to talk with the last company that serviced/pumped your tank.
What size septic tank do I need for a tiny house?
Tiny homes typically require a 500 to 1,000-gallon septic tank. Though, it’s not always possible to implement a tank of this size. In some states, for example, the minimum tank size is 1,000 gallons. There may be exceptions to this rule if your home is on wheels.
How do I calculate the size of my septic drain field?
Drainfield Size
- 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.
How often should a septic tank be pumped?
Inspect and Pump Frequently Household septic tanks are typically pumped every three to five years.
How long do septic tanks last?
A septic system’s lifespan should be anywhere from 15 to 40 years. How long the system lasts depends on a number of factors, including construction material, soil acidity, water table, maintenance practices, and several others.
How deep should a septic tank be?
Septic tanks are typically rectangular in shape and measure approximately 5 feet by 8 feet. In most cases, septic tank components including the lid, are buried between 4 inches and 4 feet underground.
Is a 500 gallon septic tank big enough?
The minimum tank size for a three bedroom house is 1200 gallons. 500 or 750 gallon tanks used to be quite common in old houses, but they are not large enough for modern households, and are from a time without automatic washers, large spa tub, dishwashers, or multiple daily showers.
How big of a septic tank do I need for a 3 bedroom house?
The correct size of the septic tank depends mostly on the square footage of the house and the number of people living there. Most residential septic tanks range in size from 750 gallons to 1,250 gallons. An average 3-bedroom home, less than 2500 square feet will probably require a 1000 gallon tank.
What is the smallest septic tank you can buy?
If you’re looking to install a septic system, the smallest tank size you’re likely to find is 750-gallon, which will accommodate one to two bedrooms. You can also opt for a 1,000-gallon system, which will handle two to four bedrooms.

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
This is mostly determined by the square footage of the house and the number of people that will be living in it, as well as other factors. A typical household septic tank holds between 750 and 1,250 gallons of water. Typically, a 1000 gallon tank will be required for a three-bedroom home that is less than 2500 square feet in size. It goes without saying that the amount of water and garbage that is placed into the system is directly proportional to the number of people who live in the residence.
A reputable septic firm is the most dependable source for determining the appropriate size septic tank for your home.
- 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.
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 are the seven most popular types of septic systems, and modern polyethylene septic tanks may be used in nearly all of these systems that require a tank, if not all of them:
- 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
A significant factor influencing system efficacy and, thus, septic tank capacity is the subterranean soil type used. In this case, local government rules have a significant role. In most cases, it is related to the standards and recommendations of a designated authority that regulates septic tank installations, which is usually the department of health. It is necessary to have a trained specialist come out to the potential installation place to undertake specific tests in order to determine whether or not the ground is acceptable for the construction of a septic tank system.
A perc test will assess whether or not the subterranean soil is capable of handling and filtering septic tank effluent in a safe and effective 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.
The findings of the analysis and testing will determine whether or not the chosen location is suitable, as well as whether or not a certain septic tank system or size will be required.
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.

They are available in both single chamber and double chamber designs.
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. 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
Septic tank sizes are determined by several factors, which you should take into consideration while selecting the most appropriate septic tank for your residence.
- 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 suitable septic tank for your property.
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.
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 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.
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.
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 increased demand. 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?
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.
- Retentions occur as a result of the bacteria present in the tank.
- Now, if the tank is insufficiently large.
- 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.
- 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?
First, we must explain what septic tanks are and what they are used for in order to understand why size matters. Septic tanks are the initial stage of a septic system’s journey through the system. You might think of them as the first stop for all of the water that comes into your home. The wastewater can originate from anywhere: the laundry, showers, toilets, or even the kitchen sink! Liquids are separated from solids in this facility. After the solids have been broken down, everything goes into the drainage system, which is the second component of the septic system.
- The bacteria in the tank is responsible for retention.
- The tank is too tiny at this point, so what?
- As a result of the influx of new wastewater, the waste is flushed out into the drainage system before the bacteria have finished their work.
- If the tank is too large, however, there will not be enough heat to support the growth of bacteria.
- The same problems would arise as a result of doing so.
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
Assuming that the tank is rectangular in shape, the dimensions are as follows: length times width times depth multiplied by seventy-five (7.5) Equals gallons A tank’s cubic capacity is calculated by multiplying its radius squared by its depth (all in feet). Volume in cubic feet multiplied by 7.5 equals volume in gallons Septic tank size is influenced by various factors, all of which are listed below: You can find them right here.
2. Number of People Residing in the House
According to whether you live alone or with 6 or more family members, the size of the tank you require varies. To calculate, use the procedure outlined above. If there are four people living in the house, they can consume up to 400 gallons of water each day on average. According to the 400-gallon rule, you should get a tank that holds at least 800 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.
If the septic system is unable to support the amount of people the property is planned to serve, you may have significant difficulties when selling or renting the home. 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.
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.
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?
There are a variety of calculations that may be used to calculate the size of the septic tank that is required for your residence. 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 average individual consumes 50-100 gallons of water each day.
Try to keep these things in mind when you’re putting together your estimate.
As your water use increases, the distance between you and the rest of the world narrows.
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
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
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.
