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.

Do you need a bigger septic tank size?

When constructing, purchasing, or renting a home, it is critical to understand the appropriate septic tank size for the land being considered. A house with the incorrect septic tank size could put you in a difficult situation if the tank becomes overflowing prematurely. The government may order you to replace your septic tank, which may cost you thousands of dollars if it fails completely. To avoid this, make certain that the septic tank is the appropriate size from the beginning.

Using the number of bedrooms to determine septic tank size

The number of beds on a property must be taken into consideration when deciding the size of the septic tank to be installed on the land, according to the legislation. This is mostly due to the fact that the number of bedrooms will provide a clear indication of the maximum number of people who will be able to occupy the property. Because the septic tank will be the initial point of contact for all of the wastewater from the residence, it is important to choose the appropriate size. The effluent should be allowed to sit in the tank for at least 24 hours before it is discharged into the drainage system.

If this is not done, the solids will flow out of the tank and into the drain field, resulting in a blockage of the drain field and the tank.

Number of bedrooms Minimum capacity in gallons
1 – 3 750
4 850
5 – 6 1,050 – 1,500

Using water usage to determine the septic tank size

Even after determining the most appropriate septic tank size based on the number of bedrooms in the house, you may choose to take additional aspects into consideration. The water usage rates of two identically sized dwellings might be drastically different. For example, if you plan to use a garburator, the amount of wastewater that will be discharged into the septic tank will increase. It is possible that you may need to account for high-volume fixtures. The flow rates of some of the most regularly used plumbing fittings, as well as the predicted demand during peak periods, are included in the table below.

USE FLOW RATE (GALLONS PER MINUTE) TOTAL USE (GALLONS)
Bathroom sink 2 1-2
Backwash filters 10 100-200 /backwash cycle
Garbage disposer 3 4-6 per day
Dishwasher 2 5/load
Kitchen sink 3 2-4/use
Shower/ tub 5 25-60/use
Toilet flush (pre-1992 design) 3 4-7/use
Toilet flush (high-efficiency design) 3 1.28/use
Washing machine 5 15-30/load

Others factors that determine the size of the septic tank

Other aspects should be taken into consideration even if the number of bedrooms is used to calculate the most appropriate size for the septic tank. The water usage rates of two identically sized homes might be vastly different! Consider that if you want to use a garburator, the amount of wastewater that will enter the septic tank will be more than usual.

Furthermore, high-volume fixtures may need to be taken into account. The flow rates of some of the most regularly used plumbing fittings, as well as the predicted demand during peak periods, are shown in the table below.

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

  • 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.

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

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

Consider the square footage of your home as another factor in selecting the most appropriate septic tank size. The size of your septic tank will be determined by the size of your residence. If your home is less than 1,500 square feet, you’ll typically need a tank that holds between 750 and 1,000 gallons. A larger residence of around 2,500 square feet will necessitate a larger tank, one that is more than the 1,000-gallon capacity.

  • Another factor to consider when determining the appropriate septic tank size for your home is the square footage of your home. The size of your septic tank will be proportional to the size of your home. For example, a house with less than 1,500 square feet normally requires a tank that holds 750 to 1,000 gallons. A larger home, say 2,500 square feet, will necessitate a larger tank, maybe in the 1,000-gallon range.

The Number of Occupants

In general, the greater the number of people that live in your home, the larger your septic tank must be. In the case of a two-person household, a modest septic tank will be necessary. If your house has more than five tenants, on the other hand, you will want a larger septic tank in order to handle your wastewater more effectively and hygienically. When determining what size septic tank to purchase, it is important to remember that the size of your septic tank determines the overall effectiveness of your septic system.

As a result, it is critical that you examine septic tank sizes in order to pick the most appropriate alternative for your property in order to avoid these difficulties. Please contact us to determine the optimal septic system size for your North Atlanta, GA house.

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.
  5. The same problems would arise as a result of this.

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. The typical water use of a person per day is 80-100 gallons, which brings us to the next aspect to consider.

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.

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.

WAC 246-272A-0232:

The size of your septic tank is critical to the overall performance of your sewage system, as well as the prevention of immediate and accumulating future problems. This article has examined the most significant considerations you should 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.

Consider doing these calculations in advance to avoid any potential complications in the future.

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.

The findings of the analysis and testing will determine whether or not the chosen site is suitable, as well as whether or not a certain septic tank system or size is required.

4) The Expected Volume of Wastewater

The typical amount of wastewater that will be generated and that the septic tank will be able to manage is the most essential factor in determining the size of the septic tank that is required. In a home with simply a septic system, all wastewater is disposed of in the septic tank unless a separate system for managing greywater is in place to handle the waste. In order to calculate and approximate these values for residential dwellings, business structures, and facilities, extensive study has been carried out.

Starting with a 1000-gallon septic tank for residential usage, the advice is to go from there.

Some experts propose adding an additional 250 gallons of septic tank capacity for each additional bedroom over three bedrooms.

This is frequently the case when considering the situation collectively for the entire household rather than individually.

Minimum Septic Tank Capacity Table

For further information on the minimum septic tank capacity dependent on the number of residential bedrooms, please see the following table:

Number of Bedrooms Minimum Septic Tank Size Minimum Liquid Surface Area Drainfield Size
2 or less 1000 – 1500 Gallons 27 Sq. Ft. 800 – 2500 Sq. Ft.
3 1000 – 2000 Gallons 27 Sq. Ft. 1000 – 2880 Sq. Ft.
4 1250 – 2500 Gallons 34 Sq. Ft. 1200 – 3200 Sq. Ft.
5 1500 – 3000 Gallons 40 Sq. Ft. 1600 – 3400 Sq. Ft.
6 1750 – 3500 Gallons 47 Sq. Ft. 2000 – 3800 Sq. Ft.

Take note of the following in relation to the table above:

  • As defined by the State of New York, the Minimum Liquid Surface Area is the surface area given for the liquid by the tank’s width and length measurements. The range of Drainfield Sizes is depending on the kind of groundwater present. The State of Michigan provides the above-mentioned drainfield recommendations, which might vary greatly depending on local standards and terrain.

Additional Thought: Can a Septic Tank Be Too Big?

In the absence of consideration for cost, it is reasonable to ask: “Can a septic tank be too large?” The answer is a resounding nay. As long as the septic tank is placed appropriately, it is impossible for a septic tank to be too large; the only thing that can happen is that it is too little. According to the majority of suggestions, constructing a larger-capacity septic tank is frequently the safer and more preferable solution. The following are the reasons behind this:

  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.

How A Septic Tank Moves Water

Wastewater is defined as water that has been discharged via a domestic faucet and into a drain. If you have water or other liquids in your tank, they will most likely run through the tank and past a filter and into the leach field. Water goes through a tank, and sediments tend to settle to the bottom as it moves through. However, when the tank gets a big volume of water at once — as is the situation while hosting guests — the solids may rush toward and clog the exit pipes.

How Many People Can A Septic Tank Handle?

It all boils down to how much water you use on a daily basis. Typical domestic water storage tanks have capacities that range from 750 gallons to 1,250 gallons, with the average individual using between 60 and 70 gallons of water each day. Specifically, when septic systems and tanks are constructed, contractors typically pick plumbing hardware based on the size of the home. This is a concern because Following an aseptic tank assessment, Jones PlumbingSeptic Tank Service can establish the suitable volume of your septic tank.

3 Tips For Caring For Your Septic System

Living with an aseptic tank is not difficult or time-consuming, but it does need preparation and patience in order to reap the benefits of the system’s full lifespan. To help you maintain your septic system, Jones PlumbingSeptic Tank Service has provided three suggestions.

1. Understand How Much Water Your Daily Activities Use

While older fixtures consume more water than modern, high-efficiency fittings, many homes have a blend of the two types of fixtures in place.

Assume that old vs new water-appliances and fixtures consume approximately the same amount of water, based on the following calculations.

  • 1.5 to 2.2 gallons per minute for bathroom sinks, 4–6 gallons each cycle for dishwashers, and 2–5 gallon per minute for kitchen sinks are recommended.
  • For example, showers use 2.1 gallons per minute, or 17.2 gallons per shower
  • Toilets use 1.28 gallons to 7 gallons every flush
  • Washing machines use 15 gallons to 45 gallons per load
  • And sinks use a total of 2.1 gallons per minute.

2. Set Up A Laundry Plan

Scheduling numerous loads over the course of a week is beneficial to the aseptic tank. Washing bedding and clothing in batches allows you to get other home duties done while you wash. Solids have time to settle and water has time to filter out in your septic tank system if you spread your water use over many days.

3. Fix Leaky FaucetsFixtures

Did you know that a running toilet may waste as much as 200 gallons of water each day if left unattended? It is possible that the sheer volume of water will produce too much water in the septic system, resulting in other problems like standing water in the yard.

Schedule Professional Septic System Care

Have you noticed that your drains are backing up in your home? Alternatively, are damp patches emerging in your yard? If this is the case, it is time to contact Jones PlumbingSeptic Tank Service to arrange for septic tank services. While most septic tanks are capable of handling a significant volume of water, they can get overwhelmed, resulting in painful consequences. To arrange an appointment with us if your system is having difficulty keeping up with household demand or if you believe it is time for a septic tank cleaning, please call us now.

Septic Tank: Size Matters

Septic systems are not the sort of system that is “one size fits all.” Even if one size tank may be sufficient for one home, this does not imply that it will be sufficient for all households. Talking with a plumbing and septic tank specialist will be your best bet for ensuring that you purchase the proper size tank for your needs. This article will provide you with the fundamental knowledge you need to get started on your home repair and plumbing projects.

Things to consider

The following factors should be taken into consideration when selecting the amount of septic tank that your property requires; for example,

  1. The square footage of the property in question
  2. What is the number of rooms in the house
  3. Who will be residing in the house
  4. How many people will be living in the house

Septic tanks are typically available in sizes ranging from 750 gallons to 1,250 gallons in capacity. We need some background information before we can get into the meat of the discussion.

What is a Septic Tank?

Septic tanks are typically available in sizes ranging from 750 gallons to 1,250 gallons. It is necessary to provide some background information before we proceed with this subject.

Are there Different Types of Septic Tanks?

That’s an excellent question! Yes, several sorts of materials are used to construct your septic tank by the manufacturer. When it comes to placing the tank, it all comes down to personal style, affordability, and maneuverability. Let us have a look at the many sorts of tanks that are most typically encountered:

Concrete Septic Tanks

Designed to endure several decades, these tanks are one of the most robust solutions available for your household plumbing requirements. However, because they are the heaviest of the materials, their upkeep and installation will almost certainly be more expensive. Another thing to keep in mind is that they are prone to cracking, which can result in wastewater spilling into the surrounding ground and potentially polluting drinking water.

Plastic Septic Tanks

These tanks are more resistant to the natural, biological, and chemical processes that will take place in your tank as a result of their construction. They are also more resistant to cracking than other types of concrete. Because they are made of plastic, they are lightweight, which makes them quite simple to install.

Unfortunately, if your earth moves or floods, plastic tanks have a tendency to shift and wander around underground. It is possible that your tank will move or possibly rise out of the ground as a result of this.

Fiberglass Septic Tanks

This sort of tank is more robust than plastic since it is less likely to flex or shift when it is placed in a stable location. Additionally, they are more cost-effective than concrete septic tanks because to their lightweight and noncorrosive nature both within and outside the tank. Unlike plastic or concrete tanks, they are also less prone to suffer structural damage than those materials.

Steel Septic Tanks

These tanks are becoming increasingly rare, but it doesn’t rule out the possibility of seeing one in the future. Steel is the least expensive of the materials used in septic tanks, but it does so at the expense of durability. Despite the fact that they are intended to endure between 20 and 25 years, they frequently rust before they have reached their entire lifespan. Now that we’ve covered the essential background material, let’s move on to the actual subject at hand.

What Size Septic Tank Do You Need?

  • Home with fewer than 1.500 square feet = 750-gallon tank
  • Home with fewer than 2,500 square feet = 1,000-gallon tank
  • Home with fewer than 3,500 square feet = 1,250-gallon tank
  • Home with fewer than 4,500 square feet = 1,250-gallon tank
  • And home with fewer than 5,500 square feet = 1,315-gallon tank
  • Home with fewer than 2,500 square feet = 1,315-gallon tank

Conclusion

Keep in mind that the information provided above is only a preliminary approximation. The actual size of the tank you want will be determined by a combination of the criteria listed above as well as the regulations of your local jurisdiction. Talking to a professional plumber and septic system installation is your best choice for ensuring that you are not only complying with local standards, but that you are also getting the “most bang for your buck.” Back-ups or the need for more frequent pumping and maintenance may result if you choose the incorrect size septic tank or if you have too many people living in a home with a smaller septic tank.
