A home with three bedrooms or fewer requires at least a 900 gallon tank. Four bedrooms requires at least a 1,000 gallon tank, and five bedrooms requires at least a 1,250 gallon tank.
- Mark each manhole location if the cover is below grade. A home with three bedrooms or fewer requires at least a 900 gallon tank. Four bedrooms requires at least a 1,000 gallon tank, and five bedrooms requires at least a 1,250 gallon tank.
How do I determine the size of my septic tank?
The larger your home, the larger the septic tank you’re going to need. For instance, a house smaller than 1,500 square feet usually requires a 750 to 1,000-gallon tank. On the other hand, a bigger home of approximately 2,500 square feet will need a bigger tank, more than the 1,000-gallon range.
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 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.
Can you have a septic tank without a leach field?
The waste from most septic tanks flows to a soakaway system or a drainage field. If your septic tank doesn’t have a drainage field or soakaway system, the waste water will instead flow through a sealed pipe and empty straight into a ditch or a local water course.
How far should drain field be from septic tank?
Common guidelines require at least 50′ clearance distance between a well and a septic system tank or 150′ between a well and a septic drainfield or leaching bed but you will see that different authorities may recommend different distances. Local soil and rock conditions can make these “rules of thumb” unreliable.
How big is a typical septic drain field?
A typical septic drainfield trench is 18 to 30 inches in depth, with a maximum soil cover over the disposal field of 36″; or per the USDA, 2 feet to 5 feet in depth.
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.
How often should a septic tank be pumped?
Inspect and Pump Frequently The average household septic system should be inspected at least every three years by a septic service professional. Household septic tanks are typically pumped every three to five years.
Is septic 5 real?
Title 5 Inspections are the seller’s responsibility and are required to be performed by a person licensed by the Massachusetts Department of Environmental Protection. Title 5 is part of the Massachusetts State Environmental Code and regulates all septic systems in Massachusetts.
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.
What size are concrete septic tanks?
What sizes do concrete septic tanks come in? Standard tank sizes are 1000 gallon, 1250 gallon, and 1500 gallons nationwide.
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.
North Carolina Septic Tank Installation Regulations
KevinDerrick/iStock/GettyImages Septic tank installation in North Carolina must meet a number of stringent regulations. According to the law, septic systems must be constructed to accommodate the soil characteristics of their respective sites and the surrounding environment. Individuals who live in single-family residences in areas where municipal or community sewage disposal is not available can use septic tanks as part of an on-site sewage disposal system. Septic tanks are used by single-family residences throughout the state where municipal or community sewage disposal is not available.
Definition
It is defined by the state as “a water-tight, covered receptacle designed for primary treatment of sewage,” which will collect sewage from buildings, separate floating waste from sinking waste, use anaerobic action to digest organic waste, store solids, and allow the liquids to drain out for further treatment and disposal.
Setbacks
Septic tanks must be located at least 100 feet away from private or public water sources, streams, and reservoirs, according to the Environmental Protection Agency. They should be kept a minimum of 50 feet away from bodies of water such as beaches, canals, marshes, storm-water retention ponds, lakes, and ponds. 15 feet should be left between septic tanks and basements, embankments, drainage system side slopes, and swimming pools to prevent clogging. It is also necessary to keep septic tanks at least 10 feet away from the edge of a property or from water lines or the up-slope component of drainage systems.
Septic tanks cannot be installed in areas where there is a risk of flooding every 10 years or fewer unless they are waterproof and capable of remaining watertight during a storm or other disaster.
Installation Specifications
Septic tanks must contain two compartments, with the intake compartment having a volume of between 2/3 and 3/4 of the tank’s total capacity, according to state regulations. Make use of an effluent filter and make sure that you have access to the filter and the tank at all times. Use a sanitary tee on both the input and output of the system. When the top of the tank is less than 6 inches above the ground surface, a manhole and cover should be installed at each tank access location. If the manhole cover is below grade, mark the position of each manhole.
Four bedrooms require a minimum of a 1,000-gallon tank, and five bedrooms demand a minimum of a 1,250-gallon tank, according to the EPA.
This support case should be at least 24 inches away from the septic tank outflow and it must be waterproof in order to be effective.
Prefabricated septic tanks are approved by regulatory bodies based on the designs for the septic system and the specifications of the tank itself.
Septic System Owner’s Guide
What kind of computer system do you have? In North Carolina, there are many distinct types of septic systems in use, but the vast majority of the over 2 million systems in use throughout the state are minor variations of the typical septic system. This system includes a septic tank as well as a drainfield that is filled with gravel (usually two to six trenches). Since the mid- to late-1990s, classic gravel aggregate trenches have been phased out in favor of innovative gravel-less trench designs, which have become increasingly popular.
- Some of the most often used gravel-free trenches nowadays are either long and narrow, tunnel-shaped chambers in the trenche, or gravel replacements such as expanded polystyrene aggregate.
- A booklet from the Cooperative Extension Service, AG-439-13, Septic Systems and Their Maintenance, outlines the typical system, easy adjustments to it, and the most significant maintenance requirements.
- The application of these technologies is now widespread, whether in new housing projects or in the replacement or repair of malfunctioning septic systems in residences and businesses.
- In order to address this, state regulations provide specified maintenance requirements for a number of these more advanced technology.
- Furthermore, state regulations mandate that the health department examine these systems on a regular basis.
- Are you familiar with the location of your septic system and repair area?
- If you do not have a copy of your septic system permit or a soil evaluation document, contact your local health department.
This Septic System Owner’s Guidefile folder should contain the following items: It is normally possible to establish the location of a septic tank and drainfield by looking at a copy of the permit and consulting with a septic contractor, a consultant, or the local health department A “repair area or replacement area,” in which a second drainfield might be constructed if necessary, has been required on nearly all home sites approved since the early 1980s, according to state law.
It should be noted on your septic system permit that this repair area was designated by the health department when the site was allowed.
Some Important Facts to Understand About Your Septic System
- In what form of septic system do you have
- Where is it situated
- And where is the repair area situated? Is the septic system up and running? In the past, has it been kept up to date? What can you do on a day-to-day basis to ensure that your system continues to function properly? What kind of maintenance will be required in the future
On the grid labeledSeptic System Layout, draw a rough sketch of your home, septic system (including both the tank and drainfield), repair area, and any other essential features (such as your driveway). The distance between the home and the access port on the septic tank should be measured and recorded when having your septic tank drained. This will assist you in locating it again. You may also want to indicate the position of your tank as well as the limits of your drainfield in your yard. If you do not have a riser installed over the access port for your septic tank, you may want to consider having one put in.
- Even when properly maintained, septic tanks can contain harmful gases and pollutants, as well as bacteria and other germs that can cause major health problems if not addressed.
- Is your septic system in proper functioning order?
- Many individuals are unaware that untreated sewage that has accumulated on the surface of the ground might be a health threat.
- Before fixing a malfunctioning septic system, you must get a permit from the local health authority, according to state regulations.
- What kind of upkeep has been carried out?
- If you are purchasing an existing house, you should ask the seller a few critical questions, such as the following:
- What is the age of the system
- What is the location of the tank and drainfield (they may or may not be on the same property or even on the same parcel of land)
- When was the last time the tank was pumped
- What is the frequency with which it has been pushed
- Is it necessary to clean the “effluent filter” in the septic tank on a regular basis (effluent filters are required for systems established after 1999)
- Has there been any indication of a likely failure? In what location can I get a copy of the permit and documentation proving how effectively (or poorly) the system has been maintained
- Do you know whether any improvements have been made to the house that would necessitate expanding the capacity of the system? Is the system still operational, and if so, when and by whom was it repaired?
If the house has only recently been constructed, request that the septic system contractor give you with a “as built” schematic, which may include elements that were not included in the permit. If the house is equipped with a pump, request that the contractor and the local health agency supply specifics on how the pump was initially installed. In order to properly care for your septic system, you must manage it on a day-to-day basis as well as perform periodic maintenance and repairs. Layout of a septic system.
- However, the drainfield does not have an indefinite capacity. The average daily water use per person is 50 gallons. Even for brief periods of time, the soil drainfield has a maximum daily design capacity of 120 gallons per bedroom, which is routinely exceeded. Overloads can occur at any time of year, on a daily basis, or on weekends. Fix any leaky faucets or toilets you may have. Water conservation will help you get more use out of your system.
Keep waste disposal to sewage alone.
- It is not acceptable to utilize your septic tank as a garbage can for items such as cigarette butts, tissues, feminine hygiene products, cotton swabs, cat litter, coffee grinds, or disposable diapers. Reduce the amount of time you use your garbage disposal. These contribute a significant amount of additional solids. It is not recommended to throw fat or cooking oil down the drain. You should avoid putting toxic chemicals into your system, such as solvents and oils. You should avoid using paint thinners and paint thinners that have been dumped. You should avoid disinfectants and pesticides. Conserve your funds. Most of the time, commercial septic tank additives are not required.
Ensure that the system is protected against physical harm (site maintenance).
- Maintain a layer of plants on the soil over the drainfield to prevent soil erosion from occurring. Don’t drive your car above the system’s limits. Try to avoid building over the system or in the repair area. The natural shape of the terrain immediately downslope of the system should be preserved, and this region should be protected against excavation (cutting and filling). Neither asphalt nor concrete should be used to cover the tank or drainfield.
All wastewater should be disposed of in a system that has been authorized.
- You shouldn’t install a separate pipe to transport washwater to a side ditch or into the woods. This is against the law
The house and the yard (site maintenance)
- Conserve and preserve the area where your septic tank and drainfield are located
- Trees that thrive in moist environments should be cut down and removed. Willows, elms, sweetgums, and certain maples are examples of such trees. Surface water should be diverted away from the tank and drainfield by landscaping the yard. Inspect the system to make sure that water from the roof, gutter, and foundation drains does not overflow
- It is recommended that if your system is located at the base of a slope, you build a french drain to channel subterranean water. Ensure that drainage ditches, subsurface tiles, and drainage outlets are kept in good condition so that water may readily flow from them.
Sewage treatment system (Septic tank)
- Tanks should be elevated if they are 6 inches or deeper below the surface. They offer quick and convenient access for solids measurement and pumping, as well as for cleaning the effluent filter. The rate at which sludge and scum build in the tank is measured. Make a note of this information and provide it to your expert pumper. Solids should be pushed out of the tank as necessary. Most septic tanks have two sections
- It is necessary to have them drained out. More information about pumping frequency can be found in the Cooperative Extension Service document AG-439-13, Septic Systems and Their Maintenance, which is available online. It is not necessary to wait till your drainfield collapses before having your tank pumped. By that time, the drainfield may have been completely destroyed. An ounce of prevention is worth a pound of cure when it comes to septic systems.

- Any system that includes a pump should be operated by a state-certified subsurface system operator. In the case of low pressure pipe (LPP) systems erected or repaired after July 1, 1992, as well as underground drip irrigation systems, aerobic treatment units (ATUs), peat biofilters, sand biofilters, textile biofilters, and other sophisticated systems, a permit will be required by law. Those interested in obtaining a list of state-certified subsurface system operators should contact the North Carolina Water Pollution Control System Certification Commission at 919-707-9089. Between planned maintenance visits, check to see that the pump and electrical components are still in proper operating order. Germs found in sewage have the potential to cause disease. Never go into a septic tank unless absolutely necessary. Toxic and explosive gases are present in the tank, posing a threat. Tanks that are more than a decade old may collapse. Electrical controls provide a risk of electric shock and sparking. Children should not be able to open the septic tank lid, hence it should be secured. Do not attempt to repair a malfunctioning system on your own time. Obtain a repair permit and employ a contractor with extensive expertise

FAQ about Septic Systems
What is the recommended frequency of septic tank pumping? A septic tank should be pumped out on a regular basis to ensure that the system is operating correctly. Pumping frequency is determined by the volume of sewage generated by the household as well as its population size and tank capacity. In general, a septic tank should be examined every 5 years to determine whether or not it requires pumping. More information may be found on the Septic Systems and Maintenance page maintained by North Carolina State University.
- A septic system should be inspected at least once every five years to see whether the septic tank needs to be pumped and whether there are any other operating issues.
- You should contact our office to have someone come out and inspect the system if you feel there is an issue, such as damp patches in that region of your yard, sluggish draining plumbing, or sewage stench.
- To keep your septic system in good working order, you should save water, avoid flushing chemicals or grease down the drain, keep the ground cover over the drain field in good condition, and have the tank inspected every five years.
- What permissions are required for the construction of a house?
- Improvement Permission: This is a permit that is provided for areas that have soil that is suitable for the installation of a sewage treatment system. Some of the properties that have recently been subdivided have already been granted with an upgrade permit. To obtain a copy of the improvement permit, please contact our office. Installation of Septic System: The construction authorization permit, which is required prior to the issuance of a building permit, authorizes the installation of the septic system. A construction permit application must be submitted with a floor plan of the building and a site plan of the land in order to be approved for construction. Water Well Permission: If your property does not have access to public water, you will also need to apply for a well permit.
What if I already have a property that I wish to renovate or expand? What should I do? The Existing System Authorization is required if you are not expanding the number of bedrooms in your home and the addition does not intrude on your septic system or well. To be considered, you will need to submit an application as well as floor plans and a site plan. Our office will conduct a site inspection and, if there are no issues, will grant the authorisation prior to the issuance of the construction permit.
- Please consult with a member of our team in order to make this judgment.
- In septic systems, the term “conventional septic system” refers to the type of drain field used.
- An underground drain field is made out of a trench filled with gravel and a pipe or some other material that allows the liquid from a septic tank to seep into the surrounding soil.
- The size of a septic system is determined by the number of bedrooms in a residence.
- To extend the size of your home from a three-bedroom to a four- or five-bedroom home on a site that already has a permit for a three-bedroom home, you will need to apply for a new improvement permit and building permission, as well as a new septic system.
- A typical 4-bedroom septic system and repair area will require around 1/4 to 1/3 of an acre of appropriate soil for installation and maintenance.
- Repair areas are areas of appropriate soil that are set aside in case the original drainfield fails for a variety of reasons.
- While one drainfield is hard at work, the other is taking a well-deserved break and rejuvenating.
- What kinds of trees may I plant in the vicinity of the septic tank?
- Planting trees near the drain field area is not encouraged, although it is an option available to property owners.
- A common misconception is that most modern drain fields have just 6 to 12 inches of back fill over them, and that planting trees too near to or on top of the drain line may cause harm to the pipe and trench.
If trees are to be planted near the drain field, it is best to avoid planting species that are known to have problematic roots in the soil. These are some of the species:
- Elms, maples, sweet gum, and willows are examples of trees having fibrous roots.
What Size Septic Tank Do I Need
The size of an underground septic tank is referred to as its total volume handling capacity in this article, and it will be discussed in further detail later in this article. For additional information on above-ground septic tanks and systems, see our page on above-ground septic tanks. The minimum septic tank capacity requirements are determined by a variety of variables. State, county, and/or city regulations may specify permitted tank sizes, as well as tank materials and installation.
The size of the septic tank will vary depending on whether it is intended for domestic or commercial usage; in this section, we will cover residential use.
Shortly stated, the required size of a septic tank will be determined by the following factors: (1) the specific septic system type; (2) local government requirements; (3) the compatibility of the ground geology; and (4) the anticipated volume of wastewater depending on the size of the residence.
However, this is not true.
Furthermore, plastic septic tanks will not corrode, are weatherproof, are waterproof, are less expensive, are lighter, and are easier to build.
1) The Specific Septic System Type
There are seven different types of septic tank systems, and the size of the tank required will vary depending on the system you choose. The scope of this article does not allow for a comprehensive discussion of each system type and its associated size requirements. We are referring to traditional gravity-fed anaerobic septic systems in this context when we say “system type.” The anaerobic septic system is the most prevalent type of septic system, and it is the one that most people think of when they imagine a septic tank.
- The following systems are available: conventional, gravity-fed, anaerobic systems
- Above-ground septic systems
- Pressure systems
- Anaerobic systems
- Mound systems
- Recirculating sand or gravel filters systems
- Bottomless sand filters systems
If your septic tank system is anything other than a traditional, anaerobic system, the instructions in this page may not be applicable in their entirety to your situation.
2) Local Government Regulations
The laws for septic tanks imposed by local governments vary greatly across the United States. In part, this is due to the significantly diverse soil geography and water features that exist from state to state and can even differ by a few miles in some cases. In order to determine the appropriate septic tank size and the best position on the land for installation, it is essential to consult with local government rules first. Take, for example, theWastewater Treatment Standards – Residential Onsite Systemsdocument from the New York State Department of Health, which provides a comprehensive informational overview of codes, rules, and regulations frequently promulgated by governing bodies, as well as common terminology and definitions in the industry.
3) Suitability of the Ground Geology
The laws for septic tanks imposed by local governments differ significantly across the country. Due to the significantly diverse soil geography and water features found in each state, and sometimes even within a few miles of one another, this is the case In order to determine the appropriate septic tank size and the best placement on the land for installation, it is critical to consult with local government officials first. Review theWastewater Treatment Standards – Residential Onsite Systemsdocument from the New York State Department of Health for an example, as well as an informative discussion of codes, rules, and regulations frequently put forward by regulatory departments, as well as common terminology and meanings.
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.

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.

Septic Tank Size: What Size Septic Tank Do You Need?
Septic tanks are used for wastewater disposal and are located directly outside your home. Private wastewater management is becoming increasingly popular in the United States, with more than 30 percent of newly constructed residences incorporating on-site wastewater management. Do you require septic tank installation and are unsure of the amount of septic tank you require? When establishing a septic tank, the most important element to consider is the type and size of septic tank that you will be installing.
A number of factors influence the size of a septic tank, which are discussed in this article.
Basics of Septic Tanks
Your septic system is a self-contained chamber that is designed to retain the wastewater generated by your home. A septic system is comprised of two major components: the soil absorption area or drain, and the holding tank. Septic tanks absorb solid waste when wastewater is discharged into them, resulting in the formation of an asludge layer at the septic tank’s base. A layer of soap residue, grease, and oil forms on the top of the water. The effluent or wastewater is contained within the intermediate layer.
To discover more about how a septic tank works, check out our page that goes into further detail on how a septic tank functions.
The Main Types of Septic Tanks
Before you start thinking about septic tank sizes, it’s important to understand the many types of septic tanks that exist.
- 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.
If your septic tank is too large for your home, there will not be enough collected liquid to support the growth of the bacteria that aids in the breakdown of solid waste in the septic tank if the tank is too large.
What Determines Septic Sizes?
Here are some of the elements that influence septic tank sizes; keep them in mind when making your purchase to ensure that you get the most appropriate septic tank for your property.
Consider Your Water Usage
The most accurate and practical method of estimating the appropriate septic tank size for your property is to calculate the quantity of water you use on a regular basis. The size of the septic tank required is determined by the amount of water that can be held in it before being drained into the soil absorption field. In many places of the United States, the smallest capacity of septic tank that may be installed is 1,000 gallons or less. The following are the suggested septic tank sizes for your household, which are based on your household’s entire water use.
- 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.

The Number of Bedrooms Your Property Has

- In general, a 1-2 bedroom house will require a 500 gallon septic tank
- A 3 bedroom house will demand 1000 gallon septic tank
- A 4 bedroom house will require 1200 gallon septic tank
- And a 5-6 bedroom house would require a 1500 gallon septic tank.
The Number of Occupants
In general, the greater the number of people that live in your home, the larger your septic tank must be. In the case of a two-person household, a modest septic tank will be necessary. If your house has more than five tenants, on the other hand, you will want a larger septic tank in order to handle your wastewater more effectively and hygienically. When determining what size septic tank to purchase, it is important to remember that the size of your septic tank determines the overall effectiveness of your septic system.
As a result, it is critical that you examine septic tank sizes in order to pick the most appropriate alternative for your property in order to avoid these difficulties.

What size of septic tank do I need?
Probably one of the last things on your mind when you are constructing a new house is the location of your septic system. After all, shopping for tanks isn’t nearly as entertaining as shopping for cabinetry, appliances, and floor coverings. Although you would never brag about it, your guests will be aware if you do not have the proper septic tank placed in your home or business.
septic tanks for new home construction
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.

How Often I Need To Get My Septic Tank Pumped?
What is the recommended frequency of septic tank pumping? How often does a septic tank need to be drained and cleaned? A septic tank should be pumped and emptied once every three to five years, as a general rule of thumb. Septic-disposal tanks are often used by houses located outside of urban areas since they do not have access to city sewer connections. A septic tank is an ecologically beneficial, safe, and natural solution to handle waste generated by a home or other building. A septic tank system may endure for many years if it is cared for, maintained, and pumped on a regular basis.
Because the solids (or sludge) are far heavier than water, they will sink to the bottom of the tank, where germs and bacteria will consume and dissolve them.
The intermediate layer of watery effluent will be discharged from the tank by way of perforated subterranean tubes to a drain or leach field, respectively.
Over time, an excessive amount of sludge will reduce the bacteria’s capacity to break down waste and will cause it to overflow into the drain field.
The question is, how often should you have your septic system pump out?
In general, the majority of sewage-disposal tanks have capacities ranging between 1,000 and 2,000 gallons.
The size of the tank has a role in deciding how frequently it should be pumped, among other things.
The size of a household is important.
In order to accommodate a 3-bedroom house, the size of the tank must be bigger than that required for a 2-bedroom house.
Consider chatting with them and enquiring about the size of their septic tank in relation to the number of people that live in their residences.
Generally speaking, increasing the number of people living in a home results in increased waste production, which affects the frequency with which a septic tank must be cleaned.
Take into consideration the whole amount of wastewater generated, which includes laundry, dishwashing, and showers.
Water consumption that is efficient can help to lengthen the life of a septic system and reduce the likelihood of blocking, supporting, and leaking.
To save time, it is preferable to spread out washing machine use over the week rather than performing many loads in one day.
Make your septic tank last longer by using environmentally friendly detergents around your house, purchasing an energy-efficient cleaning gadget that uses less water, and installing a filter to collect artificial fibers that the bacterial bacteria in your septic tank are unable to break down.
The food will not be broken down into tiny enough pieces to pass through the septic tank filter if the disposal is used.
Other strategies to assist the septic tank include taking shorter showers and installing low-flow shower heads or shower circulation restrictors to lower the amount of water entering the septic tank and allowing it to function more efficiently.
Even while maintaining a septic tank system isn’t that expensive, the expense of collecting and repairing or replacing a system that has ceased operating as a result of negligence is significantly higher.
In some cases, other systems may be capable of waiting up to 5 years between septic pumpings.
The frequency with which the tank must be cleaned is determined by the amount of waste present in the tank, rather than by a fixed time period.
