Septic systems are used for on-site wastewater management, and they are located right outside your home. Perhaps your building project is located outside of a municipal service area, or you just like the notion of conducting wastewater treatment on a private basis. The optimum septic tank size is critical to the efficient operation of any septic system, regardless of the purpose for its installation. The percolation test, also known as a perc or perk test, as well as local codes, will be used to establish the position and quantity of field lines to install.
Do I require a large or small septic tank?
Why Septic Tank Size Matters
It is your septic tank’s job to collect and treat all of the water that exits your home through your toilets, showers, laundry, and kitchen sinks. For as long as 24 hours, the water may be kept in the tank, which also serves as a separation chamber where solids are removed from liquids in the process. When it comes to separating particles from liquids, the retention time is critical. The presence of bacteria in the tank aids in the breakdown of sediments. The size of the tank has an impact on how successfully the system can separate and break down the waste materials.
Although it might seem logical to believe that a larger tank is preferable, a tank that is too large for your water usage can interfere with the formation of germs. This can have an impact on the tank’s efficiency.
Calculation by Water Usage
There are a variety of formulas that can be used to calculate the size of the septic tank that is required for your property. The most precise and dependable method is to measure water consumption. The size of the septic tank that is required is determined by the amount of water that will be handled and then dispersed into the field lines of the property. It should be noted that the minimum capacity tank permitted in many regions of the nation is 1,000 gallons. The following is a recommended tank size based on the total amount of water used by your household.
- 900 gallon tank for up to 500 gallons per day
- 1,200 gallon tank for up to 700 gallons per day
- 1,500 gallon tank for up to 900 gallons per day
- Tank holds up to 1,240 gallons per day
- Tank capacity is 1,900 gallon.
Calculations By House Size
The number of bedrooms in your home, as well as the square footage of your home, are less precise guides for determining the size of your tank. The maximum number of bedrooms that may be accommodated by a 1,000 gallon septic tank is two. It’s difficult to say due to the fact that water consumption varies depending on your situation. These estimates are based on the assumption that all bedrooms will be occupied, and the anticipated water consumption is based on this assumption. It is impossible to do these calculations if you live alone in a three-bedroom house.
The suggested tank sizes are listed below, according to the number of bedrooms in the house.
- Three bedrooms under 2,500 square feet: 1,000 gallon tank
- Four bedrooms under 3,500 square feet: 1,200 gallon tank
- And five or six bedrooms under 5,500 square feet: 1,500 gallon tank
- One or two bedrooms under 1,500 square feet: 750 gallon tank
- Three bedrooms under 2,500 square feet: 1,000 gallon tank
Estimated Cost
Similarly to the cost of any other commodities or services, the price might vary significantly based on where you reside and the current market circumstances. Let’s pretend you’re going to install a concrete septic tank for the sake of planning your project. These are by far the most prevalent, and they have a somewhat lengthy life span. The cost of a typical 1,000-gallon septic tank is between $500 and $700 dollars. The cost of upgrading to a 1,250-gallon tank will be at least $100 more. After three to five years, depending on the size of the tank, you could anticipate to have a cleaning job to do.
If you’re debating between two different tank sizes, knowing your financial constraints might assist you make your ultimate selection.

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.

What Size Septic Tank Do I Need
The size of an underground septic tank is referred to as its total volume handling capacity in this article, and it will be discussed in further detail later in this article. For additional information on above-ground septic tanks and systems, see our page on above-ground septic tanks. The minimum septic tank capacity requirements are determined by a variety of variables. State, county, and/or city regulations may specify permitted tank sizes, as well as tank materials and installation.
The size of the septic tank will vary depending on whether it is intended for domestic or commercial usage; in this section, we will cover residential use.
Shortly stated, the required size of a septic tank will be determined by the following factors: (1) the specific septic system type; (2) local government requirements; (3) the compatibility of the ground geology; and (4) the anticipated volume of wastewater depending on the size of the residence.
However, this is not true.
Furthermore, plastic septic tanks will not corrode, are weatherproof, are waterproof, are less expensive, are lighter, and are easier to build.
1) The Specific Septic System Type
There are seven different types of septic tank systems, and the size of the tank required will vary depending on the system you choose. The scope of this article does not allow for a comprehensive discussion of each system type and its associated size requirements. We are referring to traditional gravity-fed anaerobic septic systems in this context when we say “system type.” The anaerobic septic system is the most prevalent type of septic system, and it is the one that most people think of when they imagine a septic tank.
- The following systems are available: conventional, gravity-fed, anaerobic systems
- Above-ground septic systems
- Pressure systems
- Anaerobic systems
- Mound systems
- Recirculating sand or gravel filters systems
- Bottomless sand filters systems
If your septic tank system is anything other than a traditional, anaerobic system, the instructions in this page may not be applicable in their entirety to your situation.
2) Local Government Regulations
The laws for septic tanks imposed by local governments vary greatly across the United States. In part, this is due to the significantly diverse soil geography and water features that exist from state to state and can even differ by a few miles in some cases. In order to determine the appropriate septic tank size and the best position on the land for installation, it is essential to consult with local government rules first. Take, for example, theWastewater Treatment Standards – Residential Onsite Systemsdocument from the New York State Department of Health, which provides a comprehensive informational overview of codes, rules, and regulations frequently promulgated by governing bodies, as well as common terminology and definitions in the industry.
3) Suitability of the Ground Geology
The subterranean soil type has a significant impact on the efficacy of the system and, consequently, the size of the septic tank. This topic is highly tied to the rules of the local government. In most cases, it is related to the standards and recommendations of a designated authority that regulates septic tank installations, which is typically the department of health. In order to determine whether or not the ground is suitable for a septic tank system, a trained specialist must come out to the prospective installation site and conduct a series of tests.
A perc test will assess whether or not the subterranean soil is capable of handling and filtering septic tank effluent in an appropriate manner.
Whether you are hiring an experienced professional or doing it yourself, it is your obligation to contact your local oversight agency and arrange for perc tests and/or ground area evaluations to be performed.
4) The Expected Volume of Wastewater
The typical amount of wastewater that will be generated and that the septic tank will be able to manage is the most essential factor in determining the size of the septic tank that is required. In a home with simply a septic system, all wastewater is disposed of in the septic tank unless a separate system for managing greywater is in place to handle the waste. In order to calculate and approximate these values for residential dwellings, business structures, and facilities, extensive study has been carried out.
Starting with a 1000-gallon septic tank for residential usage, the advice is to go from there.
Some experts propose adding an additional 250 gallons of septic tank capacity for each additional bedroom over three bedrooms.
This is frequently the case when considering the situation collectively for the entire household rather than individually.
This article has demonstrated that septic tank recommendations are extremely diverse and depend on a variety of factors like where you reside, local government rules, subterranean soil type, house size, and the amount of wastewater that your unique home is predicted to produce.
Minimum Septic Tank Capacity Table
For further information on the minimum septic tank capacity dependent on the number of residential bedrooms, please see the following table:
| Number of Bedrooms | Minimum Septic Tank Size | Minimum Liquid Surface Area | Drainfield Size |
|---|---|---|---|
| 2 or less | 1000 – 1500 Gallons | 27 Sq. Ft. | 800 – 2500 Sq. Ft. |
| 3 | 1000 – 2000 Gallons | 27 Sq. Ft. | 1000 – 2880 Sq. Ft. |
| 4 | 1250 – 2500 Gallons | 34 Sq. Ft. | 1200 – 3200 Sq. Ft. |
| 5 | 1500 – 3000 Gallons | 40 Sq. Ft. | 1600 – 3400 Sq. Ft. |
| 6 | 1750 – 3500 Gallons | 47 Sq. Ft. | 2000 – 3800 Sq. Ft. |
Take note of the following in relation to the table above:
- As defined by the State of New York, the Minimum Liquid Surface Area is the surface area given for the liquid by the tank’s width and length measurements. The range of Drainfield Sizes is depending on the kind of groundwater present. The State of Michigan provides the above-mentioned drainfield recommendations, which might vary greatly depending on local standards and terrain.
Additional Thought: Can a Septic Tank Be Too Big?
In the absence of consideration for cost, it is reasonable to ask: “Can a septic tank be too large?” The answer is a resounding nay. As long as the septic tank is placed appropriately, it is impossible for a septic tank to be too large; the only thing that can happen is that it is too little. According to the majority of suggestions, constructing a larger-capacity septic tank is frequently the safer and more preferable solution. The following are the reasons behind this:
- With a bigger septic tank, you can adapt for changes in household consumption, such as those caused by parties or long-term guests. In the event that your family grows in size or you want to make improvements to your house, such as adding more bedrooms and bathrooms or installing new plumbing fixtures, having a bigger septic tank can save you the expense of installing a new tank.

How 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.

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 more resistant to the natural, biological, and chemical processes that will take place in your tank as a result of their construction. They are also more resistant to cracking than other types of concrete. Because they are made of plastic, they are lightweight, which makes them quite simple to install. Unfortunately, if your earth moves or floods, plastic tanks have a tendency to shift and wander around underground. It is possible that your tank will move or possibly rise out of the ground as a result of this.
Fiberglass Septic Tanks
This sort of tank is more robust than plastic since it is less likely to flex or shift when it is placed in a stable location.
Additionally, they are more cost-effective than concrete septic tanks because to their lightweight and noncorrosive nature both within and outside the tank. Unlike plastic or concrete tanks, they are also less prone to suffer structural damage than those materials.
Steel Septic Tanks
These tanks are becoming increasingly rare, but it doesn’t rule out the possibility of seeing one in the future. Steel is the least expensive of the materials used in septic tanks, but it does so at the expense of durability. Despite the fact that they are intended to endure between 20 and 25 years, they frequently rust before they have reached their entire lifespan. Now that we’ve covered the essential background material, let’s move on to the actual subject at hand.
What Size Septic Tank Do You Need?
- Home with fewer than 1.500 square feet = 750-gallon tank
- Home with fewer than 2,500 square feet = 1,000-gallon tank
- Home with fewer than 3,500 square feet = 1,250-gallon tank
- Home with fewer than 4,500 square feet = 1,250-gallon tank
- And home with fewer than 5,500 square feet = 1,315-gallon tank
- Home with fewer than 2,500 square feet = 1,315-gallon tank
Conclusion
Keep in mind that the information provided above is only a preliminary approximation. The actual size of the tank you want will be determined by a combination of the criteria listed above as well as the regulations of your local jurisdiction. Talking to a professional plumber and septic system installation is your best choice for ensuring that you are not only complying with local standards, but that you are also getting the “most bang for your buck.” Back-ups or the need for more frequent pumping and maintenance may result if you choose the incorrect size septic tank or if you have too many people living in a home with a smaller septic tank.

How Big of a Septic Tank Do I Need?
If you’re constructing a home, a septic tank is unquestionably one of the most significant considerations you should take into consideration. Septic tanks are used to dispose of wastewater outside the residence. The size of the septic tank is one of the most important elements to consider when determining whether or not it will function properly.
In this article, we’ll go over why septic tank sizes are important and how to establish the appropriate tank size for your property based on your requirements. Please continue reading.
Why Septic Tanks’ Sizes Matter?
To understand why size matters in this situation, we must first clarify what septic tanks are used for. Septic tanks are the initial stage of a septic system’s journey through the earth. They are the initial point of contact for all of the water in your home. The wastewater might originate from anywhere: the laundry, showers, toilets, or even the kitchen. Liquids are separated from solids in this facility. After the solids have been broken down, everything runs into the drainage system, which is the other component of the septic tank system.
- Retentions occur as a result of the bacteria present in the tank.
- Now, if the tank is insufficiently large.
- Because more wastewater is being pumped into the system, the waste is being driven out into the drainage system before the bacteria have finished breaking it down.
- However, if the tank is too large, there will not be enough heat to support the growth of bacteria.
- The same problems would arise as a result of this.
How to Decide What Size Is Best?
Before we get into the specifics of how much of a tank you require, we’d want to point out something very crucial.
How to Calculate a Tank’s Capacity in Gallons?
If the tank is rectangular in shape, the dimensions are as follows: Length x Width x Depth in feet x 7.5 = gallons If the tank is circular, the cubic capacity is equal to 3.14 x the radius squared x the depth (all in feet). Cubic capacity multiplied by 7.5 equals gallon capacity. There are various elements that influence the size of the septic tank that should be installed. They’re right here!
1. Water Usage
Assuming that the tank is rectangular in shape, the dimensions are as follows: length times width times depth multiplied by seventy-five (7.5) Equals gallons A tank’s cubic capacity is calculated by multiplying its radius squared by its depth (all in feet). Volume in cubic feet multiplied by 7.5 equals volume in gallons Septic tank size is influenced by various factors, all of which are listed below: You can find them right here.
2. Number of People Residing in the House
According to whether you live alone or with 6 or more family members, the size of the tank you require varies. To calculate, use the procedure outlined above. If there are four people living in the house, they can consume up to 400 gallons of water each day on average. According to the 400-gallon rule, you should get a tank that holds at least 800 gallons.
3. Size of the House
In this case, you may argue that the size of the home or the number of bedrooms it contains doesn’t important or that using such parameters would be misleading. Because there are so many circumstances in which there are vacant rooms, it’s possible that you’ll think this way. This would be the incorrect way of thinking about it, because septic tanks typically have a lifespan of 50-70 years, depending on the manufacturer. During those years, other families may be interested in purchasing or renting the house.
If the septic system is unable to support the amount of people the property is planned to serve, you may have significant difficulties when selling or renting the home. There are two methods to go about calculating the value.
Using the Number of Bedrooms in the House
Regulations such as this one determine the average use based on the assumption of two persons per bedroom. To be on the safe side, follow this formula: there are two persons in every bedroom, and each person requires 100 gallons of water. Then, add 400 gallons to the mix. This should provide you with a good idea of how large your tank should be in terms of volume. For example, if you have three bedrooms and six people, 600 + 400 equals a 1100 gallon tank.
Using Square Feet
You might double the square footage of your home by two, or you could just apply the usual estimating method, which goes as follows: If your home is smaller than 1,500 square feet, you’ll need a 750-gallon tank. If your home is smaller than 2,500 square feet, you will need a 1,000 gallon tank. If your home is smaller than 3,500 square feet, you will need a 1,250 gallon tank. If your home is smaller than 4,500 square feet, you will need a 1,250 gallon tank. If your home is smaller than 5,500 square feet, you’ll need a 1,315 gallon tank.
Wrapping Up
For example, you may double the square footage of your home by two, or you could just apply the usual estimation, which goes as follows: The tank must be 750 gallons or more if the space is less than 1,500 ft 2. The tank must be no smaller than 1,000 gallons if the space is less than 2,500 square feet. For spaces smaller than 3,500 square feet, a 1,250-gallon tank is required. For spaces smaller than 4,500 square feet, a 1,250-gallon tank is required. A tank with a capacity of 1,315 gallons is required for spaces less than 5,500 square feet.
How Much Water Can My Septic System Handle?
Jones PlumbingSeptic Tank Service hears two typical queries from customers:How long does a sewage system last? andHow much does a septic system cost. And, what is the capacity of my septic tank? The short and long answers are both: it depends on the situation. The amount of water you and others in your household consume on a daily basis has a significant impact on the answers to these questions.
How A Septic Tank Moves Water
Wastewater is defined as water that has been discharged via a domestic faucet and into a drain. If you have water or other liquids in your tank, they will most likely run through the tank and past a filter and into the leach field. Water goes through a tank, and sediments tend to settle to the bottom as it moves through. However, when the tank gets a big volume of water at once — as is the situation while hosting guests — the solids may rush toward and clog the exit pipes.
How Many People Can A Septic Tank Handle?
It all boils down to how much water you use on a daily basis. Typical domestic water storage tanks have capacities that range from 750 gallons to 1,250 gallons, with the average individual using between 60 and 70 gallons of water each day.
Specifically, when septic systems and tanks are constructed, contractors typically pick plumbing hardware based on the size of the home. This is a concern because Following an aseptic tank assessment, Jones PlumbingSeptic Tank Service can establish the suitable volume of your septic tank.
3 Tips For Caring For Your Septic System
Everyday water use is the deciding factor. In most cases, domestic water storage tanks have capacities that range from 700 to 1,250 gallons, with the average individual using 60 to 70 gallons of water each day. The difficulty is that, when septic systems and tanks are constructed, contractors frequently pick plumbing gear based on the size of the house they are working on. As part of its septic tank inspection service, Jones PlumbingSeptic Tank Service can establish the proper capacity of your septic tank.
1. Understand How Much Water Your Daily Activities Use
While older fixtures consume more water than modern, high-efficiency fittings, many homes have a blend of the two types of fixtures in place. Assume that old vs new water-appliances and fixtures consume approximately the same amount of water, based on the following calculations.
- 1.5 to 2.2 gallons per minute for bathroom sinks, 4–6 gallons each cycle for dishwashers, and 2–5 gallon per minute for kitchen sinks are recommended.
- For example, showers use 2.1 gallons per minute, or 17.2 gallons per shower
- Toilets use 1.28 gallons to 7 gallons every flush
- Washing machines use 15 gallons to 45 gallons per load
- And sinks use a total of 2.1 gallons per minute.
2. Set Up A Laundry Plan
Scheduling numerous loads over the course of a week is beneficial to the aseptic tank. Washing bedding and clothing in batches allows you to get other home duties done while you wash. Solids have time to settle and water has time to filter out in your septic tank system if you spread your water use over many days.
3. Fix Leaky FaucetsFixtures
Did you know that a running toilet may waste as much as 200 gallons of water each day if left unattended? It is possible that the sheer volume of water will produce too much water in the septic system, resulting in other problems like standing water in the yard.
Schedule Professional Septic System Care
Have you noticed that your drains are backing up in your home? Alternatively, are damp patches emerging in your yard? If this is the case, it is time to contact Jones PlumbingSeptic Tank Service to arrange for septic tank services. While most septic tanks are capable of handling a significant volume of water, they can get overwhelmed, resulting in painful consequences. To arrange an appointment with us if your system is having difficulty keeping up with household demand or if you believe it is time for a septic tank cleaning, please call us now.
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
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.
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 grass that grows on top of the soil absorption system takes use of the nutrients and water to flourish as well.
Septic tank types
The ultimate treatment and distribution of wastewater are handled by the soil absorption field. 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 provide a barrier from the elements. This method depends significantly 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 the water has been treated.
As the water moves through the soil, the mat slows its passage and helps to protect the area beneath the mat from being saturated.
In order for the bacteria to feed on the trash and nutrients in the effluent, the water must pass through unsaturated soil and then into the mat. The grass that grows on top of the soil absorption system takes use of the nutrients and water to thrive as well.
- 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.
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
All tanks must be waterproof in order to prevent water from entering as well as exiting the system during operation.
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.

Misconceptions of Septic Systems
You never have to have the septic tank pumped.As the septic system is used, the solids (sludge) accumulate on the bottom of the septic tank(s). When the sludge level increases, sewage has less time to settle properly before leaving the tank through the outlet pipe and a greater percent of suspended solids escape into the absorption area. If sludge accumulates too long, no settling of the solids will occur, and the solids will be able to directly enter the absorption area. These solids will clog the distribution lines and soil and cause serious and expensive problems for the homeowner.What the products do is break up the scum and sludge so that there is a greater percent ofsuspended solidsin the tank that then flow down the over flow pipe with the effluent to your absorption area, causing your system to fail.The absorption area is designed to treat water or effluent, not solids.The septic tank is designed to contain and treat the solids and they should remain in the tank.
When the contents (liquids and solids) in the tank reaches the level of the overflow pipe, the effluent flows down the overflow pipe to the absorption area every time water is used in the house.The tank works at this full level until it is emptied when it is pumped again.When the alarm for the pump sounds it means you need to pump your tank.If you have a system designed with a pump to pump the effluent to the absorption area you also have an alarm for the septic system.The alarm sounds when the water level rises in the pump tank and alerts you that there is a malfunction with your pump, float switches, or other component in the pump tank.It does not mean that it is time for a routine pumping of your tank.
