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:
- Generally speaking, there are seven different types of septic tank systems, and the size of the tank required will vary depending on the system you choose. It is beyond the scope of this article to provide an overview of each system type and their size requirements. Conventional, gravity-fed anaerobic septic systems are the sort of system we are talking about here. It is the anaerobic septic system that is the most commonly seen and the one that most people envision when they think of a septic tank or leach field. 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.
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.

The majority of towns require even the smallest septic tanks to carry a minimum of 1,000 gallons of wastewater. As the number of bedrooms, occupants, bathrooms, and fixtures that will be serviced by the septic system rises, the needed capacity for the system increases accordingly.
Step 1
Calculate the number of inhabitants who will be utilizing your septic system on a regular basis. The majority of towns believe that a two-bedroom house will have four regular inhabitants, even though the property only has two bedrooms. A three-bedroom residence may accommodate up to six people.
Step 2
The number of bathrooms that will be served by the septic tank should be counted. If you just have one bathroom but want to add another in the future, make sure to include the second bathroom in your count to avoid having to replace your tank further down the line.
Step 3
In your home, make a list of all of the plumbing fittings you have. This figure includes all faucets, toilets, showers, dishwashers, laundry washers, and any other fixture that will drain into your septic tank. It does not include your water heater.
Step 4
Take your calculations to your local permit office, where they will be checked against your local rules in order to establish the acceptable septic tank sizing for your home or business. The guidelines for clothing sizing differ somewhat from one place to the next. As an example, in Arizona, a three-bedroom house with two bathrooms and around 20 fixtures requires a tank that holds approximately 1,250 gallons. A 2,000-gallon water tank is required for a structure with 14 residents and three to five bathrooms.

It should be noted that in many places of the country, the smallest size tank permitted is 1,000 gallons in capacity. Tank size recommendations are based on the amount of water your household uses on a daily basis.
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

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.

- This is large enough to accommodate typical inputs without stumbling.
- Is your system capable of handling the additional load?
- This would result in sewage blockages as well as an increased danger of untreated effluent being flushed into your drainage system.
- Anaerobic microorganisms are responsible for the breakdown of waste materials.
- 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:
- Reduce the amount of water used by washing, dishwashers, and additional showers a few days before your celebration
- Preparing meals and other water-intensive cooking tasks ahead of time will save time. Invest in a portable restroom or put up some bathroom regulations to kindly inform visitors about what can and cannot be flushed
- If you haven’t done so recently, scheduling an inspection and pumping of your tank before to your party is the best option. It is essential to ensure that external inputs from eavestroughs and other sources are diverted away from the drain field.
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.

When considering the installation of a toilet on your septic system, it is important to check with the local construction authorities to ensure that you are permitted to do so. Depending on your jurisdiction, the size of your septic system is determined by the number of toilets you service, and exceeding this number without updating your tank or leach field is unlawful. Others, on the other hand, base system size on the number of beds and allow for the addition of numerous additional toilets as long as the number of people who use them does not rise.
The septic tank required for a single family house in Clackamas County, Oregon, for example, must have a minimum capacity of 1,000 gallons.
- Locate the lateral waste line, which runs from your home to the septic tank and back again. Despite the fact that it is underground, it is typically straightforward to discover after the septic tank has been identified. Finally, if everything else fails, you might go to the septic system schematic that is on file at the county planning office. Identify and plan the quickest path between the placement of your new toilet and the most convenient point of connecting to the lateral waste line. Depending on where you live, this connection point might be in the center of the yard, adjacent to your house, or even in the crawl space. If the pipe is in the yard, use a shovel to dig around it to expose it if it is hidden by vegetation. Never dig without first calling 811, which is the national call-before-you-dig phone number, to determine the location of underground utility lines. Using a drill and hole saw, create a 3-inch hole on the bathroom floor to accommodate the toilet. As mentioned in the toilet installation instructions, make certain that it is installed at the right distance from both the back and side walls. Install a toilet flange in the opening and secure it to the floor with a screwdriver. Plastic pipe cement should be used to attach a fitting to the flange that will allow you to route the waste pipe in the direction that it needs to travel. Extend the waste pipe to its tie-in point along the most convenient route, cutting pipe with a hacksaw and gluing fittings together with plastic pipe cement in many situations. Closet ells are the most common type of 90-degree drainage fitting. Strapping pipes to the floor joists that run horizontally under the house is an excellent way to keep them safe. Installing a 2-inch vent pipe will allow you to vent the toilet. A typical configuration is for it to rise from a T fitting in the waste line and extend upward to connect with the main vent stack. When employing 3-inch waste lines, the venting system must not be more than 6 feet away from the toilet flange to be effective. Under some conditions, it is acceptable to produce a wet vent through a sink drain
- Nevertheless, you should speak with your local building authorities and/or a plumber before proceeding. A vent T fitting should be used to connect the vent pipe to the main vent. The primary vent should be cut using a hacksaw, then glued in the T and the new vent pipe glued to the T. Glue in a Y fitting and glue the new waste pipe to the fitting to connect the toilet waste pipe to the lateral main sewer line.
Things You Will Need
- Shovel, drill, 3-inch hole saw, toilet flange, closet fitting
- And other tools. Plastic pipe cement, 3-inch plastic pipe and fittings, hacksaw, and other supplies are needed. Pipe straps
- 2-inch plastic pipe and fittings
- Vent T fittings
- Y fittings
- Pipe straps
Tip
Every point along the waste pipe’s passage to the septic tank must have a minimum 1/4-inch-per-foot slope to ensure proper drainage. Additionally, the vent pipe must retain the same minimum slope toward the toilet drain as it does toward the toilet. If you have access to a neighboring toilet, such as one on the other side of the wall or in an adjoining bathroom, you may be able to connect the waste line from that toilet to your own.
Warning
- Septic system modifications have the potential to modify groundwater composition, posing a threat to public health as well as the environment. It is possible that you may want a permission from both the health department and the building department for this job.
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.
How many bathrooms can a 1000 gallon septic tank support?
Do I require a large or small septic tank?

Are septic systems based on bedrooms or bathrooms?
The capacity of a septic system is assessed, or “rated,” in bedrooms. In reality, the amount of restrooms isn’t a major source of concern. The design flow of an aseptic system is based on predicted consumption, which is calculated depending on the number of bedrooms. Systems are created based on a daily water use of 110 gallons per bedroom. 310 CMR 15.203 contains the relevant regulations.
What is the average cost of a new septic system?
The average cost to install a new septic system is from $3,280 and $9,550. The average cost of a simple septic system for a three-bedroom home is $3,918; however, the majority of homeowners pay between $3,280 and $5,040. A system with two alternating pumps will cost you between $9,500 and $15,000 to install and maintain.
Can I add a second septic tank?
The quickest and most straightforward option to expand your septic tank while maintaining connected to current sewer lines is to simply add another septic tank. This increases the capacity of your home’s wastewater system and provides your septic system more time to process the wastewater before it is discharged. Connect the two septic tanks together using a 4-inch pipe.
Can a septic tank be too big?
Because an enormous septic tank can’t work properly without the proper quantity of wastewater flowing through it, it should be replaced. You may not have enough liquid stored in the tank for the essential bacteria to grow, which helps to break down the sediments in it, if it is too large for your property’s needs.
How long does septic tank last?
Typically, a steel septic tank will survive between 15 and 20 years under normal conditions. Tanks built of concrete or plastic are often considered to be the most long-lasting options. A well-maintainedseptic system with a concrete tank can survive for more than 40 years if properly kept.
How much does it cost to install a septic drain field?
In order to transport wastewater from the home to the septic tank, it will cost between $25 and $33 per linear foot for excavation, installation, and backfill, as well as an average of $1,000 to $1,500 for the tank. Installation and connection of pipes and tank Typically, an adrainorleach field will cost somewhere between $2,000 and $10,000.
How big is a typical septic drain field?
If necessary, replacement leachlines can be installed between the original lines, which can be up to 100 feet long and 1 foot to 3 feet wide. The trenches are spaced apart by six feet or more, depending on local requirements, and are sometimes constructed with enough space between the original lines to allow for future replacement leachlines to be installed.
Can you put a driveway over a septic field?
A septicdrainfield should never be situated beneath a driveway or parking lot for safety reasons. As a result of soil compaction and lack of efficient evaporation of moisture via the surface, effective drainfield operation will be compromised, virtually probably resulting in crushed and damaged pipework.

How Your Septic System Works
Underground wastewater treatment facilities, known as septic systems, are often employed in rural regions where there are no centralized sewage lines. They clean wastewater from residential plumbing, such as that produced by bathrooms, kitchen drains, and laundry, by combining natural processes with well-established technology. A conventional septic system is comprised of two components: a septic tank and a drainfield, often known as a soil absorption field. It is the septic tank’s job to decompose organic matter and to remove floatable stuff (such as oils and grease) and solids from wastewater.
Alternate treatment systems rely on pumps or gravity to assist septic tank effluent in trickling through a variety of media such as sand, organic matter (e.g., peat and sawdust), constructed wetlands, or other media to remove or neutralize pollutants such as pathogens that cause disease, nitrogen, phosphorus, and other contaminants.
Prior to discharging wastewater into the environment, several alternative systems are designed to evaporate or disinfect the effluent.
Specifically, this is how a typical conventional septic system works:
- All of the water that leaves your home drains down a single main drainage pipe and into a septic tank. An underground, water-tight container, often composed of concrete, fiberglass, or polyethylene, serves as a septic system’s holding tank. Its function is to retain wastewater for a long enough period of time to allow particles to sink to the bottom and form sludge, while oil and grease float to the surface and produce scum. Sludge and scum are prevented from exiting the tank and moving into the drainfield region by compartments and a T-shaped outlet. After that, the liquid wastewater (effluent) exits the tank and flows into the drainfield. The drainfield is a shallow, covered hole dug in unsaturated soil that serves as a drainage system. Porous surfaces are used to release pretreated wastewater because they allow the wastewater to pass through the soil and into the groundwater. In the process of percolating through the soil, wastewater is accepted, treated, and dispersed by the soil, finally discharging into groundwater. Finally, if the drainfield becomes overburdened with too much liquid, it can flood, causing sewage to flow to the ground surface or resulting in toilet backups and sink backups. Finally, wastewater percolates into the soil, where it is naturally removed of harmful coliform bacteria, viruses, and nutrients. Coliform bacteria are a kind of bacteria that may be found in the intestines of humans and other warm-blooded animals, with humans being the most common host. As a result of human fecal contamination, it is a sign of this.

Do you have a septic system?
It’s possible that you’re already aware that you have a septic system. If you are not sure, here are some tell-tale symptoms that you most likely are:
- You make use of well water. In your home, the water pipe that brings water into the house does not have a meter. In the case of a water bill or a property tax bill, you will see “$0.00 Sewer Amount Charged.” It is possible that your neighbors have a septic system
How to find your septic system
You can locate your septic system once you have confirmed that you have one by following these steps:
- Taking a look at the “as constructed” drawing of your house
- Making a visual inspection of your yard for lids and manhole covers
- Getting in touch with a septic system service provider for assistance in locating it
Failure symptoms: Mind the signs!
A bad odor is not necessarily the first indicator of a septic system that is failing to work properly. Any of the following signs should prompt you to seek expert assistance:
- Water backing up into the drains of homes and businesses
- It is especially noticeable in dry weather that the drainfield grass is bright green and spongy. The presence of standing water or muddy soil near your septic system or in your basement
- A strong stench emanating from the area surrounding the septic tank and drainfield
