How big of septic tank do I need?
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 2000 gallon holding tank need to be pumped?
How often does my holding tank need to be pumped? A holding tank may need to be pumped every 30 to 90 days depending on how much waste is generated and the size of the tank.
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 do I calculate the size of my septic drain field?
Drainfield Size
- The size of the drainfield is based on the number of bedrooms and soil characteristics, and is given as square feet.
- For example, the minimum required for a three bedroom house with a mid range percolation rate of 25 minutes per inch is 750 square feet.
How often should a septic tank be pumped?
Inspect and Pump Frequently Household septic tanks are typically pumped every three to five years.
Is a 500 gallon septic tank big enough?
The minimum tank size for a three bedroom house is 1200 gallons. 500 or 750 gallon tanks used to be quite common in old houses, but they are not large enough for modern households, and are from a time without automatic washers, large spa tub, dishwashers, or multiple daily showers.
How long do septic tanks last?
A septic system’s lifespan should be anywhere from 15 to 40 years. How long the system lasts depends on a number of factors, including construction material, soil acidity, water table, maintenance practices, and several others.
How big should a septic tank be for a 3 bedroom house?
The correct size of the septic tank depends mostly on the square footage of the house and the number of people living there. Most residential septic tanks range in size from 750 gallons to 1,250 gallons. An average 3-bedroom home, less than 2500 square feet will probably require a 1000 gallon tank.
What’s the difference between a septic system and a holding tank?
HOLDING TANKS ARE DIFFERENT FROM SEPTIC TANKS However, instead of releasing treated wastewater into the ground through a drainfield, the holding tank temporarily stores the effluent for removal and transportation to a treatment facility.
What size are sewage holding tanks?
Underground septic tanks are available in sizes ranging from 200 gallons up to 1500 gallons. An inlet and outlet may be added to tanks sized 200 gallons to 500 gallons for $75.00.
How many lids are on a septic tank?

Septic Tank Size Matters
We’ve all heard the expression, but it’s especially true when it comes to determining the appropriate septic tank size for your house, company, or land. A tank that is too tiny indicates that there is not enough time for waste to be retained in the tank, resulting in less than optimum settlements of waste material. What exactly does this imply? The bacteria that are trying to break down waste materials don’t have enough time to do their work before the rubbish is pushed out of the way to make way for more waste.
The bottom line when it comes to septic tank installation is that size does important.
What Factors Matter?
There are a variety of elements that go into estimating your water use and the amount of septic tank that is required. Although each state and county has their own minimal regulations, a good rule of thumb is that your daily sewage flow should not exceed 60 percent of your tank’s capacity on a regular basis. Keeping this in mind, some additional considerations are as follows: The number of people that live in the house and the size of the house. The amount of bedrooms and square footage of your property as well as the number of residents are all important considerations.
- Also bear in mind that this covers the number of visitors you receive and the regularity with which they arrive.
- Usage.
- What are the appliances that you use on a regular basis?
- How many showers are there?
- Obtaining an accurate assessment of your water use before installing your on-site septic system is critical when it comes to water utilization.
The Goldilocks Size
The following is a general overview that industry standards use to determine tank sizes for households: According to the Florida Department of Health, the following tank sizes are recommended for residential dwellings based on daily capacity requirements.
- A minimum of 900 Gallons Tank is required for a one-bedroom home less than 750 square feet
- A minimum of 900 Gallons Tank is required for two-bedroom homes less than 1,200 square feet
- A minimum of 1,050 Gallons Tank is required for three-bedroom homes less than 2,250 square feet
- A minimum of 1,200 Gallons Tank is required for four-bedroom homes less than 3,300 square feet
- And for each additional occupant, a minimum of 50 Gallons Tank is required.
It is crucial to note that these are only estimations at this time. The need of consulting with an on-site septic system specialist before deciding the appropriate tank size for your house or company cannot be overstated. So, which septic tank size is most appropriate for your residence? You know, not too huge, not too tiny, but just the proper amount of everything? This is the explanation and remedy provided by Chris Bryan, Licensed Septic Contractor and Owner of Advanced Septic Services of Clermont: “The size of a septic tank is determined by the estimated gallons per day of flow.” This is computed based on the number of bedrooms in the house and the quantity of living square feet in the house.
It becomes more difficult when dealing with larger residences or older properties that are being replaced. My staff and I are always delighted to compute for consumers on an individual basis, and we urge them to contact us for the best possible solution.
Lake County, Florida Septic Tank Sizing Rules
Tank size and efficiency are regulated by Lake County, Florida, which has its own set of minimum regulations. It is critical to take these into consideration when calculating your tank’s capacity, as a permit will not be provided if your tank is found to be below the minimal standards. See the basic EPA chart below, and for more detailed information on rules and requirements in Lake County, see our page on septic system permits in Lake County or contact theLake County Florida Department of Health (Lake County Florida Department of Health).

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.

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.
During the filling process, the wastewater is released from the tank and is directed to the drain field, where it is absorbed into the soil. 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
An additional issue to consider is the amount of bedrooms in your home, which will influence the size of your septic tank.
The size of your septic tank is proportional to the number of bedrooms on your home. The following table lists the appropriate septic tank sizes based on the number of bedrooms.
- In general, a 1-2 bedroom house will require a 500 gallon septic tank
- A 3 bedroom house will demand 1000 gallon septic tank
- A 4 bedroom house will require 1200 gallon septic tank
- And a 5-6 bedroom house would require a 1500 gallon septic tank.
The Number of Occupants
In general, the greater the number of people that live in your home, the larger your septic tank must be. In the case of a two-person household, a modest septic tank will be necessary. If your house has more than five tenants, on the other hand, you will want a larger septic tank in order to handle your wastewater more effectively and hygienically. When determining what size septic tank to purchase, it is important to remember that the size of your septic tank determines the overall effectiveness of your septic system.
As a result, it is critical that you examine septic tank sizes in order to pick the most appropriate alternative for your property in order to avoid these difficulties.
Do you need a bigger septic tank size?
When constructing, purchasing, or renting a home, it is critical to understand the appropriate septic tank size for the land being considered. A house with the incorrect septic tank size could put you in a difficult situation if the tank becomes overflowing prematurely. The government may order you to replace your septic tank, which may cost you thousands of dollars if it fails completely. To avoid this, make certain that the septic tank is the appropriate size from the beginning.
Using the number of bedrooms to determine septic tank size
The number of beds on a property must be taken into consideration when deciding the size of the septic tank to be installed on the land, according to the legislation. This is mostly due to the fact that the number of bedrooms will provide a clear indication of the maximum number of people who will be able to occupy the property. Because the septic tank will be the initial point of contact for all of the wastewater from the residence, it is important to choose the appropriate size. The effluent should be allowed to sit in the tank for at least 24 hours before it is discharged into the drainage system.
If this is not done, the solids will flow out of the tank and into the drain field, resulting in a blockage of the drain field and the tank.
| Number of bedrooms | Minimum capacity in gallons |
| 1 – 3 | 750 |
| 4 | 850 |
| 5 – 6 | 1,050 – 1,500 |
Using water usage to determine the septic tank size
Even after determining the most appropriate septic tank size based on the number of bedrooms in the house, you may choose to take additional aspects into consideration. The water usage rates of two identically sized dwellings might be drastically different. For example, if you plan to use a garburator, the amount of wastewater that will be discharged into the septic tank will increase.
It is possible that you may need to account for high-volume fixtures. The flow rates of some of the most regularly used plumbing fittings, as well as the predicted demand during peak periods, are included in the table below.
| USE | FLOW RATE (GALLONS PER MINUTE) | TOTAL USE (GALLONS) |
| Bathroom sink | 2 | 1-2 |
| Backwash filters | 10 | 100-200 /backwash cycle |
| Garbage disposer | 3 | 4-6 per day |
| Dishwasher | 2 | 5/load |
| Kitchen sink | 3 | 2-4/use |
| Shower/ tub | 5 | 25-60/use |
| Toilet flush (pre-1992 design) | 3 | 4-7/use |
| Toilet flush (high-efficiency design) | 3 | 1.28/use |
| Washing machine | 5 | 15-30/load |
Others factors that determine the size of the septic tank
Aside from the number of pumping chambers in a septic tank, the number of pumping chambers in a septic tank is another factor that may be used to calculate the size of the septic tank in some jurisdictions. For example, a septic tank with an incorporated lift station pumping chamber must have an extra capacity of 250 gallons in addition to the standard capacity. It is also necessary to take into consideration the local weather conditions in the location where the septic tank will be constructed.
In order to accommodate this, the septic tanks in these areas need be larger.
Legal requirements– before building and installing a septic system, it is usually a good idea to check to see if there are any legal standards that must be followed in the process.
In the event that you want to make any improvements to your house, such as the installation of another bedroom, you may want to consider installing a larger septic tank to accommodate the additional space.
Conclusion
Choosing the proper septic tank size will save you a lot of headaches in the long run. As a starting point, you will not be in contravention of any legal requirements that are in effect in your country. Additionally, by constructing the proper septic tank for your property, you can ensure that your septic system will operate properly and without interruptions throughout the year. It will also aid in the extension of the life of your septic system.
Standard Septic Systems
When it comes to treating residential wastewater, a regular wastewater system combined with a soil absorption system is the most cost-effective technique currently available. However, in order for it to function correctly, you must select the appropriate septic system for your home size and soil type, and you must keep it in good working order on a regular basis.
What size septic tank do I need?
Septic tank size requirements are determined by the number of bedrooms in a house, the number of people who live there, the square footage of a house, and whether or not water-saving gadgets are installed. If you want to obtain a general sense of what size septic tank your home requires, look at the table below.
| Bedrooms | Home Square Footage | Tank Capacity |
| 1 or 2 | Less than 1,500 | 750 |
| 3 | Less than 2,500 | 1,000 |
| 4 | Less than 3,500 | 1,250 |
| 5 | Less than 4,500 | 1,250 |
| 6 | Less than 5,500 | 1,315 |
How often should my tank be pumped?
A regular pumping of the tank is required to maintain your system operating properly and treating sewage efficiently. Sludge collects at the bottom of the septic tank as a result of the usage of the septic system. Because of the rise in sludge level, wastewater spends less time in the tank and solids have a greater chance of escaping into the absorption region. If sludge collects for an excessive amount of time, there is no settling and the sewage is directed directly to the soil absorption region, with no treatment.
You can find out how often you should get your tank pumped by looking at the table below.
If you fail to maintain the tank for an extended period of time, you may be forced to replace the soil absorption field.
Solids can enter the field if the tank is not pumped on a regular basis.
Wet soils that have been saturated by rains are incapable of receiving wastewater. Planting cool-season grasses over the soil absorption field in the winter can aid in the removal of water from the soil and the maintenance of the system’s appropriate operation and performance.
Other maintenance
A regular pumping of the tank is required to maintain your system operating properly and efficiently processing sewage. At addition to the normal usage of the septic system, sludge builds up in the bottom of the tank. Because of the rise in sludge level, wastewater spends less time in the tank and solids have a greater chance of escaping into the absorption region. Because there is no settling when sludge builds for an extended period of time, sewage flows directly into the soil absorption region with minimum treatment.
- Make use of the table below to determine how frequently you should get your tank emptied.
- The soil absorption field, on the other hand, is no longer protected from particles by the septic tank.
- Protecting soil absorption fields from solids and rainwater is essential for their long-term effectiveness.
- Rainwater runoff from rooftops or concrete surfaces should be diverted away from the soil absorption field to avoid the field becoming overflowing with liquid.
- Planting cool-season grasses over the soil absorption field in the winter can aid in the removal of water from the soil and the maintenance of the system’s correct operation and functionality.
Two critical components
A septic tank and a soil absorption system are the two primary components of a standard treatment system.
Tank
The septic tank is an enclosed, waterproof container that collects and treats wastewater, separating the particles from the liquid. It is used for primary treatment of wastewater. It works by retaining wastewater in the tank and letting the heavier particles (such as oil and greases) to settle to the bottom of the tank while the floatable solids (such as water and sewage) rise to the surface. The tank should be able to store the wastewater for at least 24 hours in order to provide time for the sediments to settle.
Up to 50% of the particles stored in the tank decompose, with the remainder accumulating as sludge at the tank bottom, which must be cleaned on a regular basis by pumping the tank out.
Drainfield
Ultimately, the soil absorption field is responsible for the final treatment and distribution of wastewater. Traditional systems consist of perforated pipes surrounded by media such as gravel and chipped tires, which are then coated with geo-textile fabric and loamy soil to create a permeable barrier. This method depends mainly on the soil to treat wastewater, where microorganisms assist in the removal of organic debris, sediments, and nutrients that have been left in the water after it has been treated.
As the water moves through the soil, the mat slows its passage and helps to prevent the soil below the mat from being saturated.
The water must be able to go into unsaturated soil in order for the bacteria present there and in the mat to feed on the trash and nutrients in the effluent. The grass that grows on top of the soil absorption system takes use of the nutrients and water to flourish as well.
Septic tank types
There are three primary types of septic tanks used for on-site wastewater treatment: cisterns, septic tanks, and septic tanks with a pump.
- Concrete septic tanks are the most popular type of septic tank. Fiberglass tanks – Because they are lightweight and portable, they are frequently used in remote or difficult-to-reach sites. Lightweight polyethylene/plastic tanks, similar to fiberglass tanks, may be transported to “difficult-to-reach” sites since they are one-piece constructions.
Septic tanks made of concrete are the most frequent. Fiberglass tanks — Because they are lightweight and portable, they are frequently used in remote or difficult-to-reach areas. Lightweight polyethylene/plastic tanks, similar to fiberglass tanks, may be transported to “difficult-to-reach” sites due to their one-piece design.
Factors in septic maintenance
A critical consideration in the construction of a septic tank is the link between the amount of surface area it has, the amount of sewage it can hold, the amount of wastewater that is discharged, and the rate at which it escapes. All of these factors influence the effectiveness of the tank as well as the quantity of sludge it retains. The bigger the liquid surface area of the tank, the greater the amount of sewage it can hold. As more particles accumulate in the tank, the water level in the tank grows shallower, necessitating a slower discharge rate in order to give the sludge and scum more time to separate from one another.
An aperture must be utilized on the tank lid if it is more than 12 inches below the soil surface, and a riser must be used on the openings in order to bring the lid to within 6 inches of the soil surface.
It is quite simple to do maintenance on the tank thanks to these risers.
Soil types
There are three types of soil textures: sand, silt, and clay, and each has an impact on how quickly wastewater filters into the soil (a property known as hydraulic conductivity) and how large an absorption field is required. Sand transports water more quickly than silt, which transfers water more quickly than clay. According to Texas laws, these three soil textures are subdivided into five soil kinds (Ia, Ib, II, III, IV). Sandy soils are classified as soil type I, whereas clay soils are classified as soil type IV.
- The Hydraulic Loading, which is the quantity of effluent applied per square foot of trench surface, is also significant in the design.
- For this reason, only nonstandard drain fields are suitable for use in clay soils due to the poor conductivity of clay soils.

How Big of a Septic Tank Do I Need?
A soil’s texture (sand, silt, or clay) has an impact on how quickly wastewater filters into the soil (known as hydraulic conductivity) and how much of an absorption field you need to install. In comparison to silt, sand transports water more quickly than clay. In accordance with Texas laws, these three different soil textures are classified as one of five soil categories (Ia, Ib, II, III, IV). The sandy soils are classified as soil type I, whereas the clay soils are classified as soil type 4.
Hydrostatic Loading, which is the quantity of effluent applied per square foot of trench surface, is also significant in the design process.
Only nonstandard drain fields can be employed in clay soils because clay soils have poor conductivity.

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,
- The square footage of the property in question
- What is the number of rooms in the house
- Who will be residing in the house
- 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 self-contained, subterranean chambers or containers that are meant to retain wastewater generated by a home or other building. Generally speaking, septic systems are composed of two major components: the tank and the drain field. As soon as the wastewater exits your home, it will begin to flow into the holding tank. Solid waste will settle to the bottom of the tank, forming a “sludge” layer on the bottom of the tank. Other liquids, such as oil and grease soap residue, will float to the surface, forming the “scum” layer on the surface.
Eventually, when the tank fills, the effluent drains from the tank and onto the drain field, where it is absorbed by the earth.
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 built to survive for several decades, making them one of the most long-lasting solutions available for your household plumbing requirements. Their installation and upkeep will, however, be more expensive due to the fact that they are the heaviest of the available materials. 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 supplies.
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.

If you’re building outside of a municipality, you’ll need a septic system installed. The septic tank is a self-contained storage tank for wastewater, in which natural bacteria breakdown human waste as a result of the presence of these bacteria. Whether you’re building a home or replacing an existing septic system, you might be thinking, “What size septic system do I need?” In order to answer this question, you must first determine how many bedrooms there are in the house and what size system the Clackamas County Soil’s Department has determined you must install.
Bedrooms in the Home Set Minimum Tank Size
The size of a septic tank is determined by the amount of liquid waste it must treat.

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:
- 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.
