How Many People Live In A 3 Bedroom House Septic Tank? (Solution)

Septic tanks are designed to accommodate the number of bedrooms in a home and potential in flows. Therefore, an average home with one to three bedrooms is intended to house four or five residents and would have a tank that would accommodate 1000 gallons. This is large enough to handle normal inputs.

  • Minimum septic tank sizes: Under current Pennsylvania law a 900 gallon septic tank is the minimum size that must be used for a home with three bedrooms or less. If six people reside in a three-bedroom house, the tank should be pumped every 1.3 years. If the same system serves a family of two, the tank would be ready for pumping every 5.2 years.

How do you calculate septic tank per person?

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.

How big of a 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 1000 gallon septic tank need to be pumped?

For example, a 1,000 gallon septic tank, which is used by two people, should be pumped every 5.9 years. If there are eight people using a 1,000-gallon septic tank, it should be pumped every year.

What is the size of septic tank for 25 users?

Existing approved design flow shall be used to determine potential number of bedrooms. Systems with a leaching area designed for 1000 gallons shall be approved for a maximum of 5 bedrooms with a 1500 gallon septic tank, 4 bedrooms with a 1000 gallon tank.

Can you put a deck over a septic tank?

You should never build a deck over a septic field; doing so will prevent the natural draining and dissipation of the effluent. This can ruin the septic system, not to mention releasing foul smells into the air all around your deck. The dissipating effluent can also rot the deck from underneath.

Bedroom Count Misrepresentation With Septic Systems

Misrepresentation of the number of bedrooms in septic systems occurs significantly more frequently than you might expect. When it comes time to put your home on the market, you naturally want to include as many bedrooms as you reasonably can since, more often than not, more bedrooms translate into a higher selling price for your property. However, if you have a septic system, you will want to take a deep breath before putting that listing on the market. A faulty septic system that is not rated for the number of bedrooms claimed by the property owner might result in significant consequences, including the possibility of a legal action being brought against the property owner.

The majority of the time, it is the real estate agent who is at fault for failing to comprehend this area of the company properly.

Unfortunately, the real estate agent sector is filled with agents who should not be permitted to possess a license, yet are still permitted to practice their profession.

When you don’t take your work and the ongoing education that comes with it seriously, you may find yourself in the position of being sued.

Consequently, if your home has four real bedrooms but the septic system capacity is only capable of supporting three, you have a three-bedroom home on your hands.

It mentions “system information” on page six of the paper, which is where the section is located.

When promoting a house, the real estate agent should use the number of bedrooms the septic system is built to handle, not the number of bedrooms that are really there.

How Septic Systems Relate to Bedrooms in a Home

Whatever their size or age, whether they’re large or tiny, old or new, all septic systems are intended to handle a set amount of waste. In order to be an informed homeowner, and particularly a home seller, you must be aware of the size of your septic system. Knowing the capacity of your septic system will allow you to establish the number of bedrooms that your home is supposed to have on the inside.

Septic system capacity is measured, or “rated”, in bedrooms.

If you look at a septic system from the outside, you may imagine that its capacity is measured in bathroom square footage. Isn’t it true that a larger septic system should be able to manage additional bathrooms? No, it is not always the case. In reality, the quantity of restrooms isn’t a major source of worry. The number of bedrooms is the source of contention. The number of bedrooms indicates the number of people who may reside in the house and, thus, the number of people who may utilize the septic system.

The design flow of a septic system is determined by the anticipated demand depending on the number of bedrooms.

The systems are developed with a daily water use of 110 gallons per bedroom in mind. 310 CMR 15.203 contains the relevant regulations. Consequently, if you have a four-bedroom house, your septic system would be able to handle 440 gallon of water every day.

You cannot have more bedrooms than the septic system can handle.

When it comes to real estate listings, you cannot advertise for more bedrooms in a property than the septic system is capable of supporting on its own. Now, the reality of the issue can be different; you might have more bedrooms in your home than the system is designed to accommodate. The residence cannot, however, be listed for sale with the buyer under the representation that the house has more bedrooms than the septic system’s bedroom capacity. The buyer may file a lawsuit if he or she discovers that the system is not rated for the number of bedrooms in the house they are considering purchasing.

Listing a home with more bedrooms than the septic system is rated for is illegal in Massachusetts.

Every state has its own set of rules governing real estate, so it’s crucial to research what you can and cannot do lawfully in your particular state before getting started. It is against the law in Massachusetts to attempt to sell your house by advertising more bedrooms than the septic system is capable of handling. Although this is not the preferred method of selling properties in the state, Realtors and home sellers continue to attempt it, most likely because they are uninformed of the regulations involving septic system ratings and home sales.

What is Considered a Bedroom Anyway?

Septic systems are one method of determining the number of bedrooms, but do you know what a bedroom is actually defined as? There is considerable ambiguity in defining a bedroom, to be sure. The following characteristics must be met in order for a room to be called a bedroom, according to standard practice:

  • Keep the space to a minimal size – the square footage of the room should be at least 70-80 square feet in most cases. It is necessary to have an escape route – normally, you will require an entrance and an exit, as well as a door and a window wide enough to allow for escape. According to the International Residential Code, a window must have a minimum opening area of 5.7 square feet, a minimum opening height of twenty-four inches, and a minimum opening width of twenty inches in order to meet the requirements of the code. In certain cases, the gap between a finished floor and a finished window sill might be as much as 44 inches. In most cases, a person must be at least seven feet tall in order to be able to walk comfortably in the space. According to your local construction rules, you may be required to install a closet in your residence. This is less clear-cut than the majority of people believe. Many individuals are under the impression that you always need a closet.

In addition to the septic system standards, you should never refer to a room as a bedroom if it does not match the conditions outlined above.

How Do Sellers Wind Up Breaking the Law?

In addition to meeting the septic system standards, you should never refer to a room as a bedroom if it does not fulfill the other conditions listed above.

Additions to the home

When homeowners build an addition to their house, they don’t usually consider the septic system that will be installed. A expanding family, for example, necessitates an increase in the square footage of the home, while improving resale value is an additional motivation for many people. When considering the addition, it is usual to overlook the consequences of what will happen to the septic system as a result of the decision. A increasing number of homeowners are also failing to get the necessary construction licenses before carrying out renovations on their properties.

In addition to breaking the law, doing so can be a huge pain in the neck when it comes time to sell your home later on.

A considerable number of purchasers will either refuse to purchase a house when the sellers have not obtained the necessary permissions, or they will require the sellers to obtain the necessary permits.

While many cities may allow a property owner to go through the permitting process, some areas are increasingly requiring property owners to pull down all of their unpermitted construction.

No one should waste their time! While you may be able to save some money by defrauding the municipality of tax funds in order to purchase a more substantial property, this may come back to haunt you in the rear end.

Basement or attic conversions

Basements and attics, in certain cases, present appealing opportunities for increasing the amount of habitable space in a property. It’s possible that they won’t be as pleasant or perfect as the original living rooms in the house, but they may be constructed of a high enough quality to be both fun and helpful. It goes without saying that completing a basement or attic has no effect on the overall capacity of the septic system. Over the years, persons selling homes in and around Metrowest, Massachusetts, have finished extra portions of the property, which has been a key contributing factor to misrepresenting the number of bedrooms in the home.

This is an obvious example of bedroom deception.

Turning small rooms into bedrooms.

Bedrooms are often defined as rooms that include at least one closet, one door, and one window that is large enough to allow for escape. The septic system rating, on the other hand, is not taken into consideration in a rapid bedroom conversion like this. What appeared to be a simple and brilliant concept for increasing the value of a property may rapidly turn into a nightmare. It happens all the time to real estate agents and house sellers – don’t be one of them! To send a tweet, simply click here.

How to Determine the Septic System Rating

It’s possible that you have documentation that demonstrates what your septic system rating is. If you do, make sure to consult with them before making any decisions about what to include in your listings. If you do not have these documents, you can ask your Realtor to check the facts at your local town hall on your behalf if you do not have them. Most board of health departments will have the information, which will be categorised as either a septic system design or a “septic as constructed.” In Massachusetts, there is another method of determining the rating of septic systems, which is referred as as a Title V rating.

In the course of the inspection and assessment, the septic system business will prepare a Title V report, which will reveal how much capacity the septic system has.

Room Counts Also Determine Septic System Capacity

One of the more obscure provisions of the Title V statute that less people are aware of is the method through which room counts are used to calculate septic system capacity. To calculate septic capacity with room counts, divide the number of rooms by two to obtain the suitable size for which the system should be developed. For example, if there are ten real rooms in a house, the house should be planned to accommodate five bedroom configuration. Taking ten rooms and dividing by two results in five bedrooms.

When there are two rooms that are back to back and have an openness that is equal to or larger than eight feet, this is referred to be one room.

Years ago, it appeared as if this section of the legislation was never enforced, but it is now being enforced by a growing number of jurisdictions.

What About a Deed Restriction?

Homeowners in several Massachusetts areas have been given the option of placing a deed restriction on their property rather than being required to update their septic system. In essence, the deed restriction states that the homeowner agrees to only market their home for the number of bedrooms determined by the septic system. Because the deed restriction is transferred with the house, the next owner will be required to comply with the restriction as well.Some towns will allow a deed restriction so that a building permit may be issued for homes that exceed the approved septic design flow based on the total room count.

The deed limitation is intended to settle any potential conflicts between the Title 5 definition of a bedroom and the actual number of bedrooms in the residence, if any exist.

As a result of the agreement, the deed limitation might be lifted in the future if public sewer is made accessible or the septic system is improved.

Do Not Expect Your Realtor to Know This!

Numerous Realtors are not aware of the legal ramifications of marketing a house with more bedrooms than the septic system is designed to handle. This is a terrible truth that must be addressed. Every now and again, real estate advertisements are posted that claim a property has a specific number of bedrooms—more bedrooms than the septic system is capable of supporting. The mistake may go undiscovered for a short period of time, but it is equally probable that the blunder will be pointed out and that ramifications will follow.

However, much as some real estate brokers utilize bad photographs, fail to advertise a house outside the Multiple Listing Service, and lack negotiating skills, some real estate agents are also oblivious of the regulations that they should be aware of.

Typically, this occurs after they have been duped into purchasing a bag of goods by a real estate agent who misrepresented the true number of bedrooms.

One More Word of Advice on Title V Inspections

What many purchasers, their real estate agents, and even lenders are unaware of is that the Title V report on which they rely may not be approved by the lender. It is common practice and assumed that the Title V report that has been circulated around has been accepted. That is not the case! From the time of the inspection, the Title V inspector has up to thirty days to submit the report to the local board of health or the DEP, whichever is sooner. It is conceivable that these entities will be unable to authorize a portion of the inspection as a result of this.

And yes, you are accurate in your interpretation of the text! It is possible that you will close on your property and subsequently discover that your Title V application has been denied!

Final Thoughts

The regulations governing septic systems might differ from one state to another. When purchasing or selling a house that is serviced by a septic system, it is critical that you be aware of the applicable laws and traditions in the area. Make careful to conduct thorough research before making a decision, or it might come back to haunt you. The ability to comprehend disclosure regulations is always important when selling a house.

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.

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. They will also not float if they are constructed appropriately.

1) The Specific Septic System Type

There are seven different types of septic tank systems, and the size of the tank required will vary depending on the system you choose. The scope of this article does not allow for a comprehensive discussion of each system type and its associated size requirements. We are referring to traditional gravity-fed anaerobic septic systems in this context when we say “system type.” The anaerobic septic system is the most prevalent type of septic system, and it is the one that most people think of when they imagine a septic tank.

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

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

2) Local Government Regulations

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

3) Suitability of the Ground Geology

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

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

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

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

4) The Expected Volume of Wastewater

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

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

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

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

Minimum Septic Tank Capacity Table

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

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

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

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

Additional Thought: Can a Septic Tank Be Too Big?

“Can a septic tank be too large?” is an useful question to ask even if you don’t consider the expense. ”. 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.

Takeaways | What Size Septic Tank Do I Need

The septic tank size recommendations offered here are merely that: suggestions. They are built on a foundation of information gathered from government and academic sources. The actual size of the septic tank you require will vary depending on the factors discussed in this article. There is no “one-size-fits-all” solution when it comes to determining the appropriate septic tank size for your property. There is a great deal of variation depending on where you reside. With addition to providing a basic insight into the septic tank and system size that may be most suited to your application, the providedMinimum Septic Tank Capacity Tablecan also assist in cost estimations.

Before beginning any septic tank installation project, check and double-check with the state, city, or local county’s agency that is in charge of septic tanks, soil testing, and permissions.

Septic System Limit(by James)Posted on:Jun 29, 2016 8:51 AMMessage:Hello all, Typically, I try to follow the rule of thumb of 2 people per bedroom, plus 1. For a 3 bedroom, that would give a maximum total of 7 people, for most properties. In most cases, I end up with somewhere between 2-4 people total. For one of my properties, it is a 3 bedroom on septic (oh how I hate septic). I called the city and they confirmed that the correct size tank is in for the house and that it is a 3 bedroom tank. According to the city, they calculate it as 2 people per bedroom, so a 3 bedroom tank would support 6 people. I tried to get them to tell me if it would violate a code or statute to have 7 people living in the house, but they were not sure if that was the case. They could only say that it was designed to support up to 6 people. I have a family that is 2 adults with 5 kids (ranging from 1to 13) that appears to be qualified. 1) Can I limit the property to 6 people, based on septic size, even if there is no code or law specifically about that? 2) Water usage wise, would kids have less of an impact on a septic system than adults?I am thinking that you would still have clothes being washed, showers/baths being taken, dishes being washed, etc. 3) I typically have had it pumped every 3 years or so and have not had any issue. Maybe I should increase it to annually and bill them for it? Thank you for any thoughts you may have.

Septic System Limit(by BRAD 20,000)Posted on:Jun 29, 2016 1:44 PMMessage:James, No.Don’t let your greed gland overpower your management. Your equipment is physically not designed for that many people. Same as if your house had only X bedrooms. 1) Yes you can limit the occupancy based on the mecahnics of the property.Write a separate policy for this house which states a limit on persons based on septic size. WMH has written about this many times.She’s on OBX with very limited septic systems and people want all their friends to pile into a beach house. 2) Believe the poo engineers. 6 max. But I suggest you reduce the wear on your homes by dropping that “+1” person AND limiting to 1 person if the bedroom is under 120sf (Indiana Health Code). Fewer bodies means less wear and less management stress on the LL! Put the limit in your add or convert one bedroom to an “office” by replacing the knob with a non-locking knob. If your septic is designed for 6 persons, believe it. I doubt the septic police will come arrest you for too many people but an overloaded system could be worse.And you know the call will come on Christmas Eve at 9 pm!In fact *I* would be cautious and back it down to 4-5 persons due to an aging system. They DO wear out and have to be totally replaced. When septic go bad it’s BAD! If you accept them you are responsible to provide septic no matter what. If they overburden your system guess who has the problem – YOU! 3) If you are having it pumped every 3 years your system is already on the edge. I’m not an expert on septic but it makes sense that even an aging system can carry a smaller amount of volume. Put all 7 in there at once and you might be overflowing in 24 hours. Manage is a verb, an active sport.This is a situation where you must make adjustments for the good of your property AND your maintenance bills. Happy flushing!

The house can not handle this many people. It’s not a good fit. and if you put them in there it will be your fault and your money to fix.Just saying, from experience. NEXT! Be your own best friend.

Factor in toilet usage and general water being used and that might be another 15 gallons per day, per person (105 gallons total)? That would mean they would be able to take an additional 4 baths per day and 2 loads of laundry per day? At this point, this is more of a thought exercise. Thoughts?

What size of septic tank do I need?

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

septic tanks for new home construction

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

For the most accurate assessment of your septic tank needs, you should speak with an experienced and trustworthy sewer business representative.

planning your drainfield

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

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

a home addition may mean a new septic tank

Vehicles should not be allowed on or near the drainfield. Planting trees or anything else with deep roots near the drain field’s bed is not recommended. Clogged pipes are frequently caused by the roots of plants; Downspouts and sump pumps should not be drained into the septic system; and If you want to tamper with or change natural drainage characteristics, do so after researching and evaluating the impact on the drain field. Do not construct extensions on top of the drain field or cover it with concrete, asphalt, or other similar materials.

Easy maintenance and inspection are made possible as a result of this; To aid with evaporation and erosion prevention, plant grass in the soil.

  • 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.

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?

Your septic system is normally buried between four inches and four feet underground, depending on the climate.

How Big of a Septic Tank Do I Need?

The size and kind of tank required for a new septic system are the two most important considerations to make before beginning the installation process. Private sewage disposal is becoming increasingly popular in the United States, with 33 percent of newly constructed residences choosing for on-site wastewater treatment as part of their construction. Septic tank systems, in conjunction with a soil absorption system, or a drain field, are the least costly way of treating residential wastewater currently available on the market.

  • The typical size of a home septic tank is from 750 gallons to 1,250 gallons in capacity.
  • The system is made up of two major components: the tank and the drain, often known as the soil absorption field or drain field.
  • Oil, grease, and soap residue combine to form the scum layer on the surface of the water.
  • With each filling of the tank, the effluent drains out of the tank and into the drain field, where it is absorbed by the earth.
  • Septic tanks are commonly utilized in residential construction and can be classified into three categories.
  • Polyethylene and fiberglass are one-piece products that are significantly lighter than steel.
  • In order to determine whether or not you need a septic tank system, check with your local building department to see what laws and requirements apply to onsite wastewater treatment.
  • The square footage of the property, the number of bedrooms, and the number of people who will be living there are all important considerations.
  • Septic tanks for one and two bedroom homes that are less than 1,500 square feet and 1,000 gallon septic tanks for three bedroom homes that are less than 2,500 square feet are recommended.
  • The figures listed above are only estimates.
  • Before acquiring a septic tank system, speak with a professional plumbing contractor who is licensed in your region about the many septic tank alternatives that are available to you.

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.

Other maintenance

Another maintenance activity that must be completed on a regular basis to protect the system from backing up is to clean the effluent filter, which is located in the tank’s outflow tee and is responsible for additional wastewater filtration. This filter eliminates extra particulates from the wastewater and prevents them from being clogged in the absorption field, which would cause the absorption field to fail prematurely. You may clean the filter yourself by spraying it with a hose, or you can have your maintenance provider clean the filter for you if necessary.

Two critical components

A septic tank and a soil absorption system are the two primary components of a standard treatment system.


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.


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 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.

  • In terms of on-site wastewater treatment, there are three primary types of septic tanks:

It is necessary for all tanks to be waterproof in order to prevent water from entering as well as exiting the system.

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.

In most cases, the riser may be extended all the way to the ground surface and covered by a sturdy lid. 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.
