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.

The size of the septic tank can be determined by the amount of water used or the size of the house. Do I require a large or small septic tank? Gary Carter/Corbis Documentary/Getty Images is credited with this image.

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.

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.

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:

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

If your septic tank system is anything other than a traditional, anaerobic system, the instructions in this page may not be applicable in their entirety to your situation.

2) Local Government Regulations

The laws for septic tanks imposed by local governments vary greatly across the United States. In part, this is due to the significantly diverse soil geography and water features that exist from state to state and can even differ by a few miles in some cases. In order to determine the appropriate septic tank size and the best position on the land for installation, it is essential to consult with local government rules first. Take, for example, theWastewater Treatment Standards – Residential Onsite Systemsdocument from the New York State Department of Health, which provides a comprehensive informational overview of codes, rules, and regulations frequently promulgated by governing bodies, as well as common terminology and definitions in the industry.

3) Suitability of the Ground Geology

The subterranean soil type has a significant impact on the efficacy of the system and, consequently, the size of the septic tank. This topic is highly tied to the rules of the local government. In most cases, it is related to the standards and recommendations of a designated authority that regulates septic tank installations, which is typically the department of health. In order to determine whether or not the ground is suitable for a septic tank system, a trained specialist must come out to the prospective installation site and conduct a series of tests.

A perc test will assess whether or not the subterranean soil is capable of handling and filtering septic tank effluent in an appropriate manner.

Whether you are hiring an experienced professional or doing it yourself, it is your obligation to contact your local oversight agency and arrange for perc tests and/or ground area evaluations to be performed.

4) The Expected Volume of Wastewater

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

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

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

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

This article has demonstrated that septic tank recommendations are extremely diverse and depend on a variety of factors like where you reside, local government rules, subterranean soil type, house size, and the amount of wastewater that your unique home is predicted to produce.

Minimum Septic Tank Capacity Table

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

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

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

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

Additional Thought: Can a Septic Tank Be Too Big?

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

  1. With a bigger septic tank, you can adapt for changes in household consumption, such as those caused by parties or long-term guests. In the event that your family grows in size or you want to make improvements to your house, such as adding more bedrooms and bathrooms or installing new plumbing fixtures, having a bigger septic tank can save you the expense of installing a new tank.

What size of septic tank do I need?

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

septic tanks for new home construction

The exact size of the septic tank is determined mostly by the square footage of the house and the number of people who will be living in it. The majority of home septic tanks have capacities ranging from 750 to 1,250 gallons. A 1000 gallon tank will most likely be required for a typical 3-bedroom home that is smaller than 2500 square feet in size. Of course, all of this is dependent on the number of people who live in the house as well as the amount of water and waste that will be disposed of through the plumbing system.

For the most accurate assessment of your septic tank needs, you should speak with an experienced and trustworthy sewer business representative. They can assist you in planning the intricacies of your septic system, including which sort of septic system will be most beneficial to you.

planning your drainfield

Here are some helpful hints for deciding where to locate your drainfield when you’re designing it.

  • Vehicles should not be allowed on or around the drainfield. Planting trees or anything else with deep roots along the bed of the drain field is not recommended. The roots jam the pipes on a regular basis. Downspouts and sump pumps should not be discharged into the septic system. Do not tamper with or change natural drainage features without first researching and evaluating the consequences of your actions on the drainage field. Do not construct extensions on top of the drain field or cover it with concrete, asphalt, or other materials. Create easy access to your septic tank cover by placing it near the entrance. Easy maintenance and inspection are made possible as a result. To aid with evaporation and erosion prevention, plant grass in the area.

a home addition may mean a new septic tank

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 to maintain your new septic system

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 increased wastewater. It is not recommended that you replace your septic system without the assistance of a certified and qualified expert.

  • Make use of the services of a qualified specialist to develop a maintenance strategy. Make an appointment for an annual examination of your septic system. Utilize the services of an effluent filter to limit the amount of particles that exit the tank, so extending the life of your septic system. Waste items should be disposed of properly, and energy-efficient appliances should be used. Make sure you get your septic system professionally cleaned every 2 to 3 years, or more frequently if necessary, by an experienced and qualified expert
  • If you have any reason to believe that there is an issue with your system, contact a professional. It is far preferable to catch anything early than than pay the price later. Maintain a record of all septic system repairs, inspections, and other activities

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?

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.

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. The recommended septic tank sizes for a home with a certain number of bedrooms are listed in the table below.

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

Using water usage to determine the septic tank size

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

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

Others factors that determine the size of the septic tank

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

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

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

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

Amazon is a good illustration of this. So, how many bedrooms can be accommodated by a 1000 gallon septic tank? The quick answer is that you can have up to three bedrooms. The actual cost, on the other hand, is dependent on a variety of factors, including the square footage of your home and the volume of wastewater you create.

Why Septic Tank Size Matters?

Everything that comes out of your home, including water from your shower, toilets, kitchen, and laundry, ends up in your septic tank. So, in other words, the first destination for all of your wastewater is your septic system. It can linger there up to 24 hours, during which the solid waste is separated from the liquids. This retention duration is critical in ensuring that solids are successfully separated from liquids throughout the separation process. In the tank, bacteria and enzymes work together to remove solid waste and break it down into liquids and gasses, which are then released into the environment.

  • The wastewater is flushed out early if the tank is too small, and the solid waste does not have a time to settle before the wastewater is flushed out.
  • The only way it can accomplish this is by draining out the wastewater that is now contained inside it – regardless of whether or not it has been adequately treated.
  • If the tank is too large for the volume of wastewater you create, it will interfere with the formation of beneficial microorganisms.
  • See the 1000 Gallon Septic Tank Dimensions and the Different Septic Tank Types.
  • For the most part, the size of the septic tank should be adequate for your requirements — neither too tiny nor too large.

What are the Different Methods of Calculating the Septic Tank Size for Your Home?

There are two basic techniques of calculating the appropriate septic tank size for your home: the size of your house and the amount of water you consume. Some municipal authorities utilize the number of bedrooms or the square footage of a residence instead of the projected wastewater flow to aid homeowners in selecting the appropriate septic system size for their home or business.

The question is, what are the appropriate septic tank sizes for a house dependent on the number of bedrooms it has? Here’s a table that you may use as a guideline when writing.

No. of Bedrooms House Square Footage Tank Capacity
1 or 2 Less than 1,500 750 gallons
3 Less than 2,500 1,000 gallons
4 Less than 3,500 1,250 gallons
5 Less than 4,500 1,250 gallons
6 Less than 5,500 1,315 gallons

Be aware that these figures are based on the assumption that all of the bedrooms in the house will be used at the same time. If you live alone in a three-bedroom house, these figures may not apply to you in all situations. Most of the time, the size of the septic system that is required is determined by the projected daily water use of a family. This is because it is the most accurate method of determining the size of a septic tank, as the most important concern when installing a new tank is that it must be able to manage the quantity of water that will be directed at it throughout its operation.

Having said that, in many parts of the United States, the minimum size for an aseptic tank is set at 1,000 gallons or less.

Daily Average Wastewater Flow Minimum Septic Tank Size
0-500 gallons per day 900 gallons
601-700 gallons per day 1200 gallons
801-900 gallons per day 1500 gallons
1001-1240 gallons per day 1900 gallons
2001-2500 gallons per day 3200 gallons
4501-5000 gallons per day 5800 gallons

When establishing a septic system, you may need to consider another aspect in addition to the number of bedrooms and the average daily wastewater flow. This consideration is the temperature of the surrounding environment. It is particularly recommended in some municipal septic rules that septic system sizes be assessed in light of the local climate in some instances. During the winter months in severe cold areas such as Alaska, the pace at which bacteria break down the solid waste in the tank is slowed by the frigid temperatures.

In contrast, if you live in an area where the environment is extremely hot or warm, you may be able to get away with a lower septic tank capacity.

Protect your septic system from large party gatherings

Unexpected water inputs from restroom use at a large party that has not been planned ahead of time might provide an unpleasant surprise for your guests. Image courtesy of pixabay.com. Christmas and New Year’s Eve are two of the most popular times of the year for us to welcome visitors, throw parties, and hold social events in our homes. If you reside in a neighborhood that has sewer systems, this will not be an issue. If you have a septic system, this might provide an issue. Considering the burden on your septic system during any time of the year, whether it’s during the holidays, at a graduation, or at another event in your house, is important.

  1. Septic tanks are built to suit the number of bedrooms in a house as well as the possibility of inflowing waste.
  2. This is large enough to accommodate typical inputs without stumbling.
  3. Is your system capable of handling the additional load?
  4. This would result in sewage blockages as well as an increased danger of untreated effluent being flushed into your drainage system.
  5. Anaerobic microorganisms are responsible for the breakdown of waste materials.
  6. The drain field is intended to aid in the breakdown process by allowing aerobic bacteria in the soil to continue working.

Because of the solids streaming into the drain field, airspace and locations for bacteria to dwell and grow are reduced in the soil, diminishing their ability to thrive. There are precautions you may take to reduce the impact of a party on your septic system. These include the following:

  • Inadequate preparation for additional water inputs from restroom use during a large party might result in a nasty surprise for your guests. Pixabay.com provided the image. Christmas and New Year’s Eve are two of the busiest times of the year for us, with guests, parties, and social events at our homes. If you reside in a neighborhood that has sewer systems, this will not be an issue for you. If you have a septic system, this can be an issue. Considering the strain on your septic system during any time of the year, whether it’s during the holidays, at a graduation, or at any other event in your house, is a good idea. Because most septic service firms are closed on weekends and holidays, requiring septic tank pumping or having a drain field fail during the holidays is an extremely difficult time of year to have a problem. Septic tanks are built to handle the number of beds in a house as well as the possibility of inflows into the tank itself. As a result, a typical home with one to three bedrooms is designed to accommodate four or five inhabitants and would contain a water tank that could hold up to 1000 gallons of liquid. When dealing with regular inputs, this is a good size. This effect would be magnified if there were a big number of people in attendance. Is your system capable of coping with the additional demands placed upon it? A huge amount of water created by a big number of visitors in a short period of time might possibly overrun the capacity of the tank and drain field in a septic system if it floods unexpectedly and rapidly. This would result in sewage blockages as well as an increased chance of untreated effluent being flushed into your drainage field. It takes approximately 24 hours for your septic tank or onsite waste water system to digest and settle out the solid inputs into the system. Anaerobic bacteria are responsible for decomposition of the garbage. This settling and breakdown period is reduced or eliminated when your system is completely submerged in water. In order for the breakdown process to proceed, aerobic bacteria in the soil need to be present in the drain field. As the water slowly flows back into the water cycle, the soil layers serve to filter it even more thoroughly before it returns to the environment. Because of the solids streaming into the drain field, airspace and locations for bacteria to live and grow are reduced in the soil, diminishing their ability to flourish. To reduce the impact of a party on your septic system, there are many actions you may take.

By anticipating your guests’ water consumption in advance, you may have a stress-free Christmas party without having to worry about a septic situation arising.

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 is a bedroom? Why does it affect your septic system?

This may appear to be a strange question demanding a straightforward response. However, it is one of the most commonly misunderstood and misrepresented aspects of a house. Much more important is to ask: “Why does it matter?” and “To whom does it matter?” The topic of what constitutes a bedroom has implications for persons who are:

  1. Building a new house, remodeling or adding an extension to a current home, and purchasing an existing property from either a private seller or a real estate agent are all options for homeowners.

Allow me to begin by tying this to a situation that occurred a few weeks ago. I received a phone call from a prospective client who was searching for help. He had recently made the decision to finish the second story of his Cape Cod-style home, which was now under construction. Upon completion, he intended to utilize the finished areas as an office and a hobby room, respectively. This seems to be a straightforward process. When he went to the local building department to obtain a permit, he was informed by the sanitarian that the space he was completing was regarded a prospective bedroom, despite the fact that he had no intention of utilizing either space as a sleeping place.

In order to build these extra “bedrooms,” he would also need to expand his present septic system, which was explained to him at that point.

First, why did the sanitarian consider the spaces to be bedrooms?

The sanitarian decided that they had easy access to the restroom on the first level in this particular instance. As a result, based on his assessment, he concluded that the second-floor spaces may be utilized as bedrooms, or as private sleeping quarters for people. However, even if the present owner intends to use the rooms as an office and a hobby room, the spaces would be deemed a third or fourth bedroom and might be utilized as such by new owners if the house is sold in the future.

Second, what did that have to do with the size of the septic system?

Many people believe that the size of a septic system is proportional to the number of bathrooms in a house. This is not true. This is completely false! The number of bedrooms in a house determines the size of the septic system required. Consider the following scenario: if your home was initially built as a three-bedroom house, the septic system was most likely intended to accommodate the projected capacity of the house (6 people; 2 per bedroom). To satisfy the demands of an additional two people, you must expand your septic system to include a fourth room or whatever the building authority or health code considers a bedroom.

Septic Systems and Additions To Your Home

The lesson here is that if you have a septic system, you must take into account the system’s present capacity when planning a new addition or renovation that may be deemed a new bedroom. This is also a useful reminder for real estate professionals. There have been a few instances when Realtors have listed properties on the Multiple Listing Service (MLS) when the number of bedrooms did not match the capacity of the septic system. For example, the listing said that the home had 4 bedrooms, but the buyer subsequently learns that the septic system is only rated for 3 bedrooms.

The buyer has the right to file a lawsuit against the seller and the Realtor.

The majority of health agencies should have information on file in the form of a septic design or “septic as-constructed.” You may look forward to a follow-up article in a few days in which we will discuss bedrooms in further detail and how they are defined by ambiguous health code criteria.
