- The inlet pipe collects the water waste in the septic tank, long enough that the solid and liquid waste is separated from each other. The outlet pipe also called the drain field, moves out the preprocessed wastewater from the septic tank and spreads it evenly in the soil and watercourses. After a while, the wastewater separates in 3 layers.
What is outlet in septic tank?
The septic tank outlet tee blocks floating scum and sewage from flowing out of the tank where it would rapidly clog the drain field and effluent piping.
How do you unclog a septic tank outlet?
Sprinkle the drain with baking soda, then dump vinegar into the pipe. Leave the mixture to sit in the pipe for an hour or two. Finally, flush the drain with hot water. If the clog is small, this could be enough to clear the pipe.
How do septic tank systems work?
How does a septic tank work? Septic tanks, whether they are single or multi-chambered, utilise the simple process of gravity to separate the liquid waste from the solid waste that flows into it from your property. The lighter solids in the waste, along with oil and grease, float to the surface and form a “scum” layer.
How do you tell if your septic tank is full?
How to tell your septic tank is full and needs emptying
- Pooling water.
- Slow drains.
- An overly healthy lawn.
- Sewer backup.
- Gurgling Pipes.
- Trouble Flushing.
Do all septic tanks have alarms?
All septic systems that use a pump to move wastewater from a septic pump tank to a drainfield or mound have an alarm installed in the house. The alarm goes off when wastewater is not being pumped from the septic pump tank to the drainfield or mound.
How do I find my septic tank outlet pipe?
The outlet pipe should be approximately 3 inches below the inlet pipe. Inlet Baffle: The inlet baffle is installed on the inlet pipe inside the tank.
Where is the outlet baffle in septic tank?
Septic baffles are located at the junctions where pipes enter and exit the tank. The one at the inlet pipe is called the inlet baffle, and the one at the outlet is called the outlet baffle.
How many inlets does a septic tank have?
Every septic tank contains two baffles, one at the inlet and one at the outlet. The goal of both baffles involves routing waste water through the tank, while ensuring that solids remain safely segregated.
Why is my septic tank full again?
There may be several reasons why you have an overfilled septic tank. An overfilled septic tank is often a signal that your drain field is malfunctioning. The water flow backs up when your drain field floods, causing the water level in your septic tank to rise. Other common issues are plumbing and excess water use.
Will a flooded septic tank fix itself?
Most septic tanks are not damaged by flooding since they are below ground and completely covered. However, septic tanks and pump chambers can fill with silt and debris, and must be professionally cleaned. If the soil absorption field is clogged with silt, a new system may have to be installed.
Why is there water coming out of my septic tank?
The top of the septic tank is usually a few feet below the soil. If you see standing water above the drainfield or tank, your septic system is likely flooded. When you don’t see obvious standing water over the area, check the water level with a probe, or use an auger to dig down into the soil.
What are the 3 types of septic systems?
Types of Septic Systems
- Septic Tank.
- Conventional System.
- Chamber System.
- Drip Distribution System.
- Aerobic Treatment Unit.
- Mound Systems.
- Recirculating Sand Filter System.
- Evapotranspiration System.
How are septic tanks connected?
A septic tank will be connected with two pipes (for inlet and outlet). The inlet pipe is used to transport the water waste from the house and collect it in the septic tank. It is kept here long enough so that the solid and liquid waste is separated from each other. The second pipe is the outlet pipe.
How do septic tanks look?
Septic tanks are typically rectangular in shape and measure approximately 5 feet by 8 feet. In most cases, septic tank components including the lid, are buried between 4 inches and 4 feet underground. You can use a metal probe to locate its edges and mark the perimeter.
How Does a Septic Tank Work?
Mr. Fix-It-Up-For-The-Family You may save a lot of money if you understand how a sewage treatment system works—and what can go wrong—so that you can handle your own septic system maintenance.
How does a septic tank work?
Pumping the tank on a regular basis eliminates sludge and scum, which helps to keep a septic system in good working order. It is possible for a well-designed and well built septic system to last for decades, or it might collapse in a matter of years. It is entirely up to you as long as you can answer the question of how do septic tanks function. Healthy septic systems are very inexpensive to maintain, but digging up and replacing a septic system that has completely collapsed may easily cost tens of thousands in labor and material costs.
It’s critical to understand how a septic tank works in order to maintain one.
Let’s take a look below ground and observe what happens in a properly operating septic system, shall we?
Understand that a septic system is a cafeteria for bacteria
Bacteria are responsible for the proper operation of a septic system. They break down garbage, leaving water clean enough to safely percolate down into the soil. The entire system is set up to keep bacteria healthy and busy at all times. Some of them reside in the tank, but the majority of them are found in the drain field. 1. The septic tank is the final destination for all waste. 2. The majority of the tank is filled with watery waste, referred to as “effluent.” Anaerobic bacteria begin to break down the organic matter in the effluent as soon as it enters the system.
- A layer of sludge settles to the bottom of the container.
- Scum is mostly constituted of fats, greases, and oils, among other substances.
- Grease and oils float to the surface of the water.
- (5) A filter stops the majority of particles from reaching the exit pipe.
- The effluent is discharged into the drain field.
- Effluent is allowed to leak into the surrounding gravel because of holes in the drain septic field pipe.
- The garbage is completely decomposed by aerobic bacteria found in gravel and dirt.
- Potable water seeps into the groundwater and aquifer system from the surface.
Septic Tank Clean Out: Don’t abuse the system
Septic systems that have been correctly planned and constructed require just occasional ‘pumping’ to remove the sludge and scum that has built up inside the tank.
However, if you don’t understand how a septic tank works, you may unintentionally hurt or even destroy the system.
- Drains are used to dispose of waste that decomposes slowly (or not at all). Cigarette butts, diapers, and coffee grounds are all known to cause issues. Garbage disposers, if utilized excessively, can introduce an excessive amount of solid waste into the system. Lint from synthetic fibers is emitted from washing machine lint traps. This substance is not degraded by bacteria in the tank and drain septic field. Bacteria are killed by chemicals found in the home, such as disinfecting cleansers and antibacterial soaps. The majority of systems are capable of withstanding limited use of these products, but the less you use them, the better. When a large amount of wastewater is produced in a short period of time, the tank is flushed away too quickly. When there is too much sludge, bacteria’s capacity to break down waste is reduced. Sludge can also overflow into the drain field if there is too much of it. Sludge or scum obstructs the flow of water via a pipe. It is possible for tree and shrub roots to obstruct and cause harm to a drain field. Compacted soil and gravel prevent wastewater from seeping into the ground and deprive germs of oxygen. Most of the time, this is caused by vehicles driving or parking on the drain field.
Get your tank pumped…
Your tank must be emptied on a regular basis by a professional. Pumping eliminates the accumulation of sludge and scum that has accumulated in the tank, which has caused the bacterial action to be slowed. If you have a large tank, it may be necessary to pump it once a year; but, depending on the size of your tank and the quantity of waste you send through the system, you may go two or three years between pumpings. Inquire with your inspector about an approximate guideline for how frequently your tank should be pumped.
…but don’t hire a pumper until you need it
Inspections and pumping should be performed on a regular basis. However, if you’re not afraid of getting your hands dirty, you may verify the sludge level yourself with a gadget known as The Sludge Judge. It ranges in price from $100 to $125 and is commonly accessible on the internet. Once you’ve verified that your tank is one-third full with sludge, you should contact a professional to come out and pump it out completely.
Install an effluent filter in your septic system
Garbage from your home accumulates into three distinct strata. The septic filter is responsible for preventing blockage of the drain field pipes.
Septic tank filter close-up
The septic tank filter is responsible for capturing suspended particles that may otherwise block the drain field pipes. Obtain an effluent filter for your tank from your contractor and place it on the outflow pipe of your tank. (It will most likely cost between $50 and $100, plus labor.) This device, which helps to prevent sediments from entering the drain field, will need to be cleaned out on a regular basis by a contractor to maintain its effectiveness.
Solution for a clogged septic system
If your septic system becomes clogged and you find yourself having to clean the filter on a regular basis, you might be tempted to simply remove the filter altogether. Hold on to it. Solids, wastewater, and scum are separated into three levels in septic tanks, which allows them to function properly (see illustration above). Solids sink to the bottom of the container, where microbes breakdown them. The scum, which is made up of trash that is lighter than water, rises to the surface. In the drainage field, the middle layer of effluent leaves the tank and goes through an underground network of perforated pipes to the drainage field.
- Keep the effluent filter in place since it is required by your state’s health law.
- Waste particles might flow through the filter and clog the perforated pipes if the filter is not used.
- Your filter, on the other hand, should not require cleaning every six months.
- A good chance is high that you’re flushing filter-clogging things down the toilet, such as grease, fat, or food scraps.
- A garbage disposal will not be able to break down food particles sufficiently to allow them to flow through the septic tank filtration system.
- Plastic items, disposable diapers, paper towels, nonbiodegradable goods, and tobacco products will clog the system if they are flushed through it.
For additional information on what should and should not be flushed down the toilet, contact your local health authority. More information on removing lint from your laundry may be found here.
Get an inspection
The temptation to just remove the filter may arise if your septic system becomes blocked and you have to clean it on a regular basis. It should be preserved. Solids, effluent, and scum are separated into three levels in a septic tank, which allows waste to be separated into three layers (see illustration above). Microorganisms breakdown the particles that settle to the bottom of the tank. It is the scum that floats on top because it is made up of trash that is lighter than water. In the drainage field, the intermediate layer of effluent leaves the tank and is carried away by subterranean perforated pipes.
- Keep the effluent filter in place since your state’s health law mandates it.
- In addition, removing the filter may result in a far bigger (and more expensive) problem down the road.
- Cleaning and unclogging the system would need substantial digging.
- The majority of filters don’t need to be cleaned until the tank is pumped, which occurs every two to five years on average, and then only when necessary.
- Food disposal is an error that many people make.
- Solids can accumulate in a septic tank to levels as high as 50% more than normal.
- More information on what should not be flushed down the toilet can be obtained by contacting your local health authority.
Alternatives to a new drain field
If an inspection or a sewage backup reveal that your drain field is in need of replacement, the only option is to replace it completely. As a result, it’s important to talk with a contractor about other possibilities before proceeding with the project.
- Pipes should be cleaned. A rotating pressure washer, used by a contractor, may be used to clean out the drain septic field pipes. The cost of “jetting” the pipes is generally around $200. Chemicals should be used to clean the system. A commercial solution (not a home-made one) that enhances the quantity of oxygen in the drain field should be discussed with your contractor before installing your new system. Septic-Scrub is a product that I suggest. A normal treatment will cost between $500 and $1,000. Make the soil more pliable. The practice of “terra-lifting,” which involves pumping high-pressure air into several spots surrounding the drain field, is authorized in some regions. Some contractors use it to shatter compacted dirt around the pipes. Depending on the circumstances, this might cost less than $1,000 or as much as $4,000 or more.
Protect your drain septic field from lint
When this device is in place, it inhibits lint from entering the system, especially synthetic fibers that bacteria are unable to digest. One of these filters, which I’ve designed and termed theSeptic Protector, was invented by me. An additional filter is included in the price of around $150 plus delivery. Learn more about how to filter out laundry lint in this article.
Don’t overload the septic system
Reduce the amount of water you use. The volume of water that flows into your tank, particularly over a short period of time, can be reduced to avoid untreated waste from being flushed into your drain field.
Replace outdated toilets with low-flow ones, install low-flow showerheads, and, perhaps most importantly, wash laundry throughout the week rather than just on Saturday mornings to save water.

Everything You Need to Know About Your Septic Tank
What is a septic tank, and how does it work? A septic tank is a water-tight container that is often constructed of concrete, fiberglass, or polyethylene to prevent flooding (plastic). In fact, it is only one component of the entire septic system, which includes several other components such as a distribution box, pumps, float switches, aerators, filters, and other accessories. Septic systems are used to treat wastewater on-site in many rural and suburban areas that do not have access to centralized sewage systems.
The components of a conventional septic tank are depicted in the diagram below.
- The Tank: This is the water-tight tank into which wastewater from your house is sent once it has been collected. A hole, fracture, or any other structural damage should not be present. Access Ports: When a trained pumper comes to clean up your tank, they will utilize an access port. When it comes to tank cleaning, it is critical that the access port be large enough to allow the pumper to move the hose about within the tank properly. A common application for risers is to elevate septic tank access above ground level, eliminating the need to dig up your septic tank every time it has to be pumped. Last but not least, the access port should be securely covered with a child-resistant lid. It is vital for the protection of your family that septic tank lids are securely fastened with screws and that they are not cracked or damaged. Pipes for entering and exiting the septic tank: Wastewater from your house enters the septic tank through the intake pipe. After the particles have settled out, the effluent is discharged from the septic tank through the exit pipe and into the drainage field. There should be roughly 3 inches between the output pipe and the intake pipe. A baffle is fitted on the intake pipe within the tank, and it serves to keep the water out. It provides a variety of functions. Additionally, it helps to avoid the build-up of scum and its backup into the intake pipe It is also important for solids to settle in the tank that the input baffle be properly installed. When wastewater enters the septic tank, it should hit the entrance baffle, which will reduce the flow and prevent the tank from becoming agitated. This permits the contents of the septic tank to remain at rest, allowing the solids to sink to the bottom of the tank. The intake baffle can also prevent odorous odors from entering the sewage line and spreading throughout the home or business
- And It is even more crucial than the inlet baffle to have an exit baffle in place because it helps to prevent scum and other particles from flowing directly into the outflow pipe and eventually into the drain field. Gas Deflector/Effluent Filter: As gas bubbles climb to the top of a septic tank, they may bring sediments with them. This is why an effluent filter is used. A gas deflector prevents these solid-carrying gases from entering the output line by preventing them from entering. However, while not every septic tank is equipped with an effluent filter, it is strongly suggested as an additional safety to prevent particulates from entering your drain field.
Any of the above-mentioned components in your septic tank should be checked for damage or missing parts as soon as possible, and the problem should be resolved by a septic system specialist. What is the operation of a septic tank? Each and every drop of wastewater from your home is channeled via a main drainage pipe and into your septic tank. Solids are prevented from entering your drain field by using the septic tank, which is just a settling tank that serves as a filter. Ideally, the water should be kept in the tank for at least one day in order to allow time for the solids to settle.
- Heavy materials, such as dirt and digested waste, will sink to the bottom of the tank and form a sludge layer at the bottom of the tank.
- Effluent is the term used to describe the liquid that exists between the sludge and scum layers.
- It is critical that solids are given adequate time and space to settle before being used.
- In fact, the Pennsylvania Department of Environmental Protection mandates a minimum capacity of 900 gallons for any new septic tank installations in the state (the table below shows recommended septic tank capacities for different sized homes).
- Ideally, you should have your septic tank emptied every two to three years, according to the Pennsylvania Septage Management Association (PSMA).
- If a drain field has been ruined by a buildup of sediments, it might cost tens of thousands of dollars to rebuild it.
- It is crucial to understand that your septic tank must be completely filled with liquid in order to function effectively.
- The septic tank diagram shown above depicts the correct operating level of a septic tank in a residential setting.
- The result is that whenever more wastewater is added to the tank, an equal volume of effluent will be discharged from the tank and drain into the drain field.
- The opposite is true if the liquid level is higher than the outflow line, which may signal a blockage in a line downstream from the septic tank or in the drain field.
If you’re wondering if your septic tank is full, a skilled pumper will consider it “full” once solids have filled one-third of the tank’s capacity. This is the time of year when your septic tank will need to be pumped.
WHAT SEPTIC BAFFLES ARE AND HOW THEY WORK
In its most basic form, your septic tank separates liquids from solids, then retains the solids until they can be pumped out while sending the liquids to a distribution field. However, this system is far more complicated than it appears at first look. However, these procedures might be a little more sophisticated than they appear at first glance. It is possible that certain sections of the tank, even if they are the simplest and most basic, may need to be replaced from time to time, such as the baffles at the entrance and outflow, as well as the baffle filter (also called effluent filter).
- FUNCTIONS OF THE SEPTIC BAFFLE Septic baffles are situated at the intersections where pipes enter and exit the tank to prevent clogging.
- In many cases, the outlet baffle is regarded as the most critical baffle, since it prevents particles from departing the tank and making their way to the leach field, where they might clog and effectively damage the leach field system.
- Unfortunately, this baffle is also the first to give way under its own weight.
- Its purpose is to aid in the smooth flow of wastewater into the tank while minimizing disturbance of the scum layer.
- MATERIALS FOR SEPTIC BAFFLE Several types of septic baffles are available, some of which are constructed of concrete and others, particularly newer variants, which are composed of plastic such as ABS.
- The exit baffle is frequently equipped with an effluent filter, which increases the effectiveness of the baffle in terms of keeping solids out of the leach field.
- The effluent filter will need to be updated on a regular basis after that, but this is a small price to pay for avoiding having to redo your leach field as a result.
- Once a year, or whenever your tank is pumped out, you should have the concrete baffles checked for structural soundness.
- Among the other baffle issues include blocked outlet baffles or outlet baffle filters, leaks at the baffle-to-tank connection, and inlet baffle obstructions, among other things.
- Baffle blockages can also arise as a result of tree roots entering the system through the input pipe or around the baffle.

How a Septic System Works
|The septic system is a sewage treatment and disposal system.A basic system consists of a septic tank and drainage area. All flows from the house are directed by way of a main sewer line to the septic tank. 40% of household sewage is from the toilet, 30% is from bathing, 15% is from laundry and 10% is from the kitchen.
What is a Septic Tank?The septic tank is a watertight chamber constructed of concrete or poly material. An average size is approximately 1000 gallons to 1500 gallons in capacity. Most septic tanks have one or two compartments. Two compartment tanks, or two single compartment tanks in series, provide better settling of the solids.Each septic tank has an inspection port over each baffle as well as a manhole access port. The manhole lid needs to be accessed for the tank to be pumped. These can be found at or below the ground surface. Typically you will find 4” diameter plastic lids at the ground surface that are the inspection ports over either of the baffles on the tank and not where the tank is to be pumped through.The baffles of the tank are one of the most important components in the septic tank. The inlet baffle forces the wastewater from the sewer line down into the tank instead of across the surface of the tank and into the outlet pipe leading to the absorption area. The outlet baffle prevents the scum layer from moving into the soil absorption area. In a properly functioning septic tank the solids and sludge settle to the bottom and accumulate, scum (lightweight materials including paper, fats and greases) rises to the surface and the effluent (liquid) in the tank existing between those layers overflows to the absorption area.
|The absorption area uses the ability of the stone and soil to filter and treat the remaining effluent. Examples of absorption areas are seepage beds, trenches, sand mounds or older cesspools / seepage pits. A cesspool is a block walled dirt bottom pit. Cesspools are no longer an installation choice but there are many properties that still have functioning cesspools. Odors and gasses from the septic system, that are always present, are vented through pipes on the house roof.For further information: -On Lot Sewage System Owner Manual -A Homeowner’s Guide to Septic Systems – by EPA
What Is A Septic Tank & How Does It Work?
Many individuals are unfamiliar with the notion of septic tanks. However, for those households that do make use of one, they are extremely important. If you’ve always lived in a property that has been linked to the city’s main sewage system, it’s likely that you haven’t ever heard of a septic tank, let alone understood what it is. What a septic tank is and how it functions will be discussed in detail in this blog.
What Is A Septic Tank?
Essentially, a septic tank is an underwater sedimentation tank that is used to treat waste water through the processes of biological decomposition and drainage. A septic tank is a wastewater treatment system that uses natural processes and time-tested technology to treat wastewater from residential plumbing, such as that produced by bathrooms, kitchen drains, and laundry. The design of a septic tank system is pretty straightforward. It is a subterranean waterproof container (usually rectangular or spherical) composed of fibre glass, plastic or concrete.
- septic tank systems are classified as “simple on-site sewage facilities” (OSSFs) since they only provide rudimentary sewage treatment.
- Excreta and wastewater are collected in a large underground tank, and they are mostly utilized in rural regions to keep the environment clean.
- It is common for them to be comprised of two chambers or compartments, as well as a tank that collects wastewater via an entrance pipe.
- This will be maintained and managed by a local water business.
- There are, however, certain additional measures that must be observed.
- Homeowners who have a septic tank have an added responsibility to ensure that their tank does not have an adverse influence on the surrounding environment.
How Does A Septic Tank Work?
It is the job of a septic tank to break down organic waste and separate it from floatable substances (such as oils and fats) and solids in wastewater. Two pipelines will be installed to connect a septic tank (for inlet and outlet). Septic tanks are equipped with intake pipes, which are used to convey water waste from homes and collect it in the tank. It is stored here for a sufficient amount of time to allow the solid and liquid waste to be separated from one another. The second pipe is the pipe that goes out.
- This pipe transports pre-processed effluent from the septic tank and disperses it evenly over the land and watercourses of the area.
- (as seen in the illustration above) The top layer is comprised of oils and grease, and it floats above the rest of the waste.
- Wastewater and waste particles are found in the intermediate layer of the wastewater system.
- Bacteria in the tank try their best to break down the solid waste, which then allows liquids to separate and drain away more readily from the tank.
What is left at the bottom of the tank must be removed on a regular basis as part of the tank’s basic maintenance. This is one of the reasons why a septic tank is considered to be a rudimentary type of sewage disposal.
The Step-by-step Process of How a Septic Tank Works
- Water from your kitchen, bathroom, and other areas drains into a single main drainage pipe that leads to your septic tank. The septic tank, which is located underground, begins the process of storing waste water. It must maintain this condition for an extended period of time so that particles settle to the bottom and oil and grease float to the top. Following the completion of this operation, the liquid wastewater (effluent) will be allowed to escape the tank and enter the drainfield. This effluent is dumped into the environment through pipelines onto porous materials. The soil is able to filter wastewater through the use of these. In the process of percolating through the soil, wastewater is accepted, treated, and dispersed by the soil
- The wastewater eventually discharges into groundwater. Last but not least, the wastewater percolates into the soil, where it is naturally removed from the environment by coliform bacteria, viruses and nutrients.
A single main drainage pipe transports water from your kitchen, bathroom, and other areas to your septic tank. The septic tank, which is located underground, begins the process of collecting and storing wastewater. Solids must sink to the bottom for a long enough period of time, allowing for the accumulation of oil and grease on their way to the surface. This technique will allow liquid wastewater (effluent) to depart the tank and into the drain field once it has been treated; This effluent is dumped into the environment through pipelines onto porous ground surfaces.
As wastewater percolates through the soil and eventually discharges into groundwater, the soil takes, processes, and disperses it.
3 THINGS TO KNOW ABOUT SEPTIC TANK BAFFLES
By Admin on November 12, 2020 Your efforts to live as environmentally conscious as possible, as a responsible homeowner, are likely already underway, with practices such as recycling, composting, and purchasing energy-efficient equipment among your list of accomplishments. As a septic tank owner, you want to make sure that whatever you put into your tank and septic field is causing the least amount of ground pollution as is reasonably practicable. Fortunately, there are a number of modest improvements you can do immediately to make your septic system even more ecologically friendly than it already is.
- Have your septic tank inspected and pumped on a regular basis.
- A larger septic tank and only a couple of people living in your home, for example, will not require pumping as frequently as a smaller septic tank or as a septic tank that must handle the waste products of several family members will require.
- When in doubt about how often to pump your septic tank, consult with a professional for advice.
- In addition to locating and repairing any damage, a professional can ensure that the septic field is in good working order and that your septic tank is functional, large enough to handle your family’s waste, and not causing any unwanted pollution in nearby ground water.
- Avoid flushing non-biodegradable items down the toilet or down the toilet.
- Items that are not biodegradable are unable to properly decompose in the septic tank and might cause the system to get clogged.
- In addition to causing issues in your house, septic system backups can damage ground water in the area surrounding your septic field.
Towels made of paper Products for feminine hygiene Grease or fats are used in cooking.
A blockage in your septic tank might be caused by a large number of food waste in the tank.
Instead of dumping food scraps into your tank, try using a backyard compost pile as an alternative that is more environmentally friendly.
Cutting back on water consumption is one of the most straightforward methods to save money while also protecting the environment and keeping your septic system from being damaged.
Your tank will ultimately fill too rapidly as a result of this, and the layer of waste floating on top of the tank will be pushed into the septic field and, eventually, into the ground water surrounding your field.
The following are some basic steps you can take to make your septic system more ecologically friendly: save water, maintain your septic system and tank, and recycle wastewater. To get answers to any of your septic tank-related issues, get in touch with the experts at Upstate Septic Tank, LLC.
How a Septic System Works – and Common Problems
This Article Discusses Septic Tanks are a type of septic tank that is used to dispose of waste. Field Sizing and System MaintenanceProblems with the Leach FieldSystem Performance Questions and comments are welcome. See Also: Septic System Frequently Asked Questions Articles on SEPTIC SYSTEM may be found here. In areas where there are no municipal sewage systems, each home is responsible for treating its own sewage on its own land, which is known as a “on-site sewage disposal system,” or septic system, more commonly.
One of the most commonly seen types of leach field is composed of a series of perforated distribution pipes, each of which is placed in a gravel-filled absorption trench.
The wastewater is collected in the septic tank once it has been discharged from the residence. Septic tanks are normally between 1,000 and 2,000 gallons in capacity and are composed of concrete, strong plastic, or metal, depending on the model. Highly durable concrete tanks, which should endure for 40 years or more provided they are not damaged, are the most common. In order to maximize efficiency, many contemporary tanks contain two chambers.Wastewater from the home accumulates in the septic tank, where it separates and begins to decompose before going to the leach field, where it is treated further.
- In the tank, oil and grease float to the top of the tank, forming scum, while solid waste sinks to the bottom, forming sludge.
- The particles at the bottom are subjected to a variety of bacteria and other microorganisms that begin breaking down the materials in an anaerobic (without oxygen) process, which is described below.
- Solids and grease must be pumped out of the system on a regular basis in order for it to function correctly.
- Each gallon added to the tank results in one gallon being discharged to the leach field, leach pit, or other similar treatment facility.
When used properly, a leach field (also known as a “drain field”) is a series of perforated pipes that are typically buried in gravel trenches 18 to 36 inches below grade — deep enough to avoid freezing, but close enough to the surface that air can reach the bacteria that further purify the effluent (see illustration below). As little as 6 inches might separate you from the ground surface, depending on your soil type and municipal regulations. It is customary to cover the perforated pipes with approximately two inches of gravel and a layer of topsoil that is 18 to 24 inches in depth.
- Grass is often sown above the ground.
- The leach field is comprised of rows of perforated pipes in gravel trenches that are used to spread wastewater over a vast area in order to further purify it.
- A bacteria-rich slime mat forms where the gravel meets the soil, and it is responsible for the majority of the water purification work.
- Despite the fact that wastewater freezes at a far lower temperature than pure water, freezing is still a hazard in cold areas.
- The leftover pathogens are converted into essential plant nutrients by these organisms, while sand, gravel, and soil filter out any solids that remain.
- If the system is operating effectively, the filtered wastewater will return to the aquifer as naturally clean water that is suitable for human consumption at this stage.
- Alternative systems may be permitted in situations when traditional leach fields are unable to function properly owing to poor soil conditions or a high water table.
These systems sometimes cost twice or three times as much as a regular system and require significantly more upkeep. Special systems may also be necessary in regions where there are flood plains, bodies of water, or other ecologically sensitive areas to protect against flooding.
SIZING THE LEACH FIELD
Using perforated pipes put in gravel-filled trenches, the drain field is sized to accommodate the number of beds in the house. In order for the system to function successfully, the leach field must be appropriately sized for the soil type and amount of wastewater, which is normally determined by the number of bedrooms in the house. In order for the liquid to seep into the soil, it must be permeable enough to do so. As a result, the denser the soil, the larger the leach field that is necessary.
- Better to have surplus capacity in your system than to have it cut too close to the bone.
- Septic tank backup into your house, pooling on the surface of the earth, or polluting local groundwater are all possibilities if the ground is incapable of absorbing the liquid.
- Dense clay soils will not absorb the liquid at a sufficient rate, resulting in a backlog.
- If the soil is mostly composed of coarse sand and gravel, it might drain at such a rapid rate that untreated sewage can poison the aquifer or damage surrounding bodies of water.
- Alternative systems may be permitted in situations when traditional leach fields are unable to function properly owing to poor soil conditions or a high water table.
- Near flood plains, bodies of water, and other ecologically sensitive places, special systems may also be necessary to protect people and property.

If you take good care of your system, you will be rewarded with years of trouble-free operation. Pumping the septic tank on a regular basis is necessary to remove the particles (sludge) and grease layer (scum) that have built up in the tank. The solids will ultimately overflow and spill into the leach field, decreasing its efficacy and diminishing its lifespan if this is not done. The rehabilitation of a clogged leach field is difficult, if not impossible; thus, constant pumping is essential!
Cooking fats, grease, and particles may also wash into the leach field if the tank is too small for the amount of water being used or if the tank is overcrowded on a regular basis.
Extra water from excessive residential consumption or yard drainage can overwhelm the system, transporting oil and particles into the leach field and causing it to overflow.
In addition, don’t try to complete a week’s worth of laundry for a family of five in a single day. This will assist you in keeping the load controlled and will also help to extend the life of your system. To minimize overburdening the system, the following measures should be taken:
- Distribute your washing loads and other high-water-use activities across the week
- And In the kitchen and bathroom, use low-flow appliances, faucets, and fixtures. Toilets, in general, are the source of the greatest amount of water use. Water should be diverted away from the leach field from the yard, gutters, and basement sump pumps.
Also, refrain from flushing solids, harsh chemicals, and just about anything else down the toilet or sink other than biological waste and white toilet paper. Also, refrain from using garbage disposals in the kitchen. If you really must have one, keep it for small non-meat bits only. Avoid flushing chemicals or paints down the toilet since many chemicals can kill beneficial microorganisms or cause water pollution in the surrounding area.Avoid flushing the following down the toilet:
- Grease, fats, and animal scraps
- Paints, thinners, chemicals, and pharmaceuticals
- And a variety of other materials sanitary napkins, tampons, and other supplies Paper towels and disposable diapers are examples of such products. Egg shells, coffee grounds, and nut shells are all good options. Antibacterial soaps and antibiotics are available.
It is preferable to put grass over the leach field and to refrain from driving or parking in the vicinity. Excessive weight placed on top of the drain field might compress the earth, diminishing its efficiency as a drain field. Drain pipes can also become clogged by trees and plants with invasive roots. In order to prevent damage to the leach field, the following measures should be taken:
- Heavy machinery should not be driven, parked, or stored on top of the leach field (or septic tank). Placement of a deck, patio, pool, or any other sort of construction over the leach field is prohibited. Remove any large trees or other plants with deep roots from the leach field. Grass is the most effective groundcover.
Even with careful use and routine maintenance, however, leach fields are not guaranteed to survive indefinitely. It is inevitable that the soil will get saturated with dissolved elements from the wastewater, and that the soil will be unable to absorb any more incoming water. The presence of an odorous wet area over the leach field, as well as plumbing backups in the house, are frequently the first indicators that something is wrong. Many municipalities mandate septic system designs to incorporate a second “reserve drain field” in the case that the first field fails.
A well constructed and maintained system should last for at least 20 to 30 years, if not longer than that.

SEPTIC SYSTEM PERFORMANCE PROBLEMS
Poor original design, abuse, or physical damage, such as driving heavy trucks over the leach field, are the root causes of the majority of septic system issues. The following are examples of common conditions that can cause a septic system to perform poorly: Plumbing in the home. clogged or insufficient plumbing vents, a blockage between the house and the septic tank, or an insufficient pitch in the sewer pipe leading from the house are all possible causes. Sewage tank to leach field connection Septic tank and leach field blockage caused by a closed or damaged tank outlet, a plugged line leading to the leach field caused by tree roots, or a blockage caused by sediments that overflowed from the tank Piping in the leach field.
- Most of the time, tree roots do not make their way through the gravel bed and into the perforated pipe.
- Reduced flows, achieved through the use of flow restrictors and low-flow faucets and fixtures, may be beneficial.
- Because of the seasonal high water table, the soil around the trenches might get saturated, reducing the soil’s ability to absorb wastewater.
- This may frequently be remedied by adding subsurface drains or curtain drains to intercept the water flow into the leach field region and to lower the water table in the immediate area around the drainage system.

Where is Septic Tank Outlet?
|Author:Septic Tank Yank (CO)ruraldiy,We have a plugged up septic tank and want to put in a cleanout for the pipe to the field from the septic tank.If your septic tank is “plugged up”, installing a cleanout in the effluent pipeline will not solve your problem.The solution to a “plugged up” septic tank is to have the contents of the tank removed by a septic tank pumper.How deep from the top would I expect to find the output drain?If the tank is a manufactured precast concrete septic tank, the top of the effluent outlet pipeline should be 10 or 12 inches below the top of the tank wall.Typically, the tank outlet is on the opposite wall from the tank inlet.Before you install a cleanout in the effluent pipeline, think about how effective this cleanout will be in solving the problem causing the failure of your septic system.In my view there is no need for a cleanout in the effluent pipeline.If the leach field is totally clogged, cleaning the distribution pipes in the leach field will not cause the leach field to perform properly again.My advice to you is to consider modifying your system to the standards that are defined in the following response to an inquiry posted on the Plbg.com Discussion Forum by a fellow self-named “Dumbdad”.Author: Septic Tank YankDumbdad, sure sounds to me like the septic man is right. If you decide to have the leach field replaced, consider installing 2-half sized leach fields equipped with a 4-inch, NDS brand diversion valve. Cover the valve riser with a 10-inch round irrigation valve box to allow for easy access. The top of the box is set at the final grade elevation. The valve will allow the alternation of flow to the fields. Use half the field for 1-year while the other half rests. Turn the valve annually on the 4th of July, SEWAGE INDEPENDENCE DAY. Celebrate your independence of the sewer grid, and remember that with this independence comes the responsibility of a sewage treatment system operator.I recommend the use of plastic leach field chambers such as the ADS Bio-Diffuser, or Infiltrator brand. Cover each chamber leach field with a 4-foot wide sheet of geotextile fabric (landscaping fabric). The geotextile will prevent the migration of silt into the void under the chambers. The fabric also acts as a wick, wicking by capillary attraction, the effluent up over the chamber units and then into the soil.Install 4-inch monitoring and ventilation ports to the ground surface on each end of each field. The 4-PVC risers are covered with plastic 6-inch round irrigation valve boxes. The tops of the irrigation valve boxes are set at the final grade elevation. The boxes will allow easy location, easy access, and you can run the lawn mower right over them. Typically the covers of the boxes are green.The tops of the in-use field monitoring ports are fitted with 4-inch female threaded adapters, and threaded plugs to prevent sewer gas odors from emanating into the yard. The tops of the resting field ventilation ports are fitted with a 4-inch female adapters, and plastic drain grates.The ventilation ports will allow atmospheric oxygen to enter the leach field, and this will create an aerobic condition in the resting leach field. The oxygen will oxidize the Ferric sulfide (that black slimy crap), a major component of the clogging mat. Also, the aerobic condition will allow the aerobic microbes, present in the surrounding soil, to migrate to the clogging mat and consume the organic matter constituent of the clogging mat, and consume the dead bodies of all their anaerobic microbial cousins. Exchange the solid threaded plugs with the drain grates when the valve is turned on SEWAGE INDEPENDENCE DAY.While you are involved with the major renovation of your septic system, I recommend that 20-inch plastic risers be installed over the inlet manhole, and the outlet manhole of the septic tank. The covers of the risers should be at the final grade elevation to allow easy access to the tank. Let’s face it, if you must excavate the soil over the septic tank manhole with a shovel, chances are that this chore will be avoided. I use Tuf-Tite brand risers.I also recommend that the outlet tee of the tank be fitted with a septic tank effluent filter. The brand that I use is manufactured by SIM/TECH (the big bottlebrush type), although there are several other high quality filters on the market.The filter will reduce the organic matter in the effluent from flowing into the leach field. Clean the filter annually on SEWAGE INDEPENDENCE DAY.Another chore that should be performed annually is the measurement of the sludge accumulation in the primary chamber of the septic tank. The sludge can be measured with a “SLUDGE JUDGE.” Do an Internet search to obtain this neat device. I recommend the implementation of the “1/3 RULE” of sludge removal. When the level of the sludge is 1/3 the total liquid depth of the septic tank, it is time to remove it.The final chore to be performed on SEWAGE INDEPENDENCE DAY is to record all of the maintenance performed on the system in a maintenance log. I prepare a SEWERS CAN BE BEAUTIFUL operation manual for each of the septic systems that I install for my clients. The manual contains a description of the system design, photos of the system components, an as-built plan, a description of the required maintenance procedures, a copy of the permit, and the maintenance log. The manual becomes an excellent sales tool when the time comes to sell the home. The manual answers all questions a potential buyer may have regarding the performance of the septic system, and will allay the fears typically encountered when purchasing a home served by a septic system.Well Dumbdad, I had better end this lengthy diatribe. If all soil absorption type septic systems were designed and constructed to the above standards, then there would be far fewer failed septic systems. Maintenance is the key to successful septic systems. However, if the required maintenance is difficult, or impossible, then chances are it will not be performed. If you would like photos of my typical standard system, send me your e-mail address. My address [email protected] Aldrich (Septic Tank Yank)Septic System ConsultantTimnath, Colorado
How Does A Septic Tank Work? Learn How Septic Systems Treat Wastewater
Many homeowners are terrified by the thought of having a septic tank because they believe it would be difficult to repair and expensive to maintain in the future. With regular maintenance, a well-constructed septic system may survive for up to forty years. Knowing the ins and outs of your septic system is essential to getting the most out of it. We’ll go over the fundamentals, such as how a septic tank works, what it is, and how to maintain it so that it lasts as long as possible.
What is a Septic Tank?
Septic systems are considered unusual and out of date by many people. As many as one in every five American houses, particularly in rural regions, is equipped with an aseptic tank. A septic tank is a large underground tank that is used to store and treat sewage. It enables homes to securely dispose of wastewater from bathrooms, showers, dishwashing, and other sources by transporting it outside of the home. Septic tanks, as well as the machinery that supports them, are placed underground. For safety reasons, they are usually put at least 10 feet away from the home when possible.
The most common materials used to construct a septic tank are concrete and plastic.
Septic tanks are available in a variety of sizes to accommodate different sized residences.
What is a Septic Tank Used For?
The water that runs from your residence is frequently polluted, making it dangerous to drink or handle in any way. Bathing, cleaning dishes, and doing laundry all contribute to the production of polluted water. Septic tanks treat wastewater that goes through the system by the use of natural and mechanical processes, respectively. It doesn’t matter where it emanates from within the house, either. In order to restore water to the earth, it must first be cleaned of undesired particles and organic materials.
Septic systems are used to treat wastewater when there are no public sewer systems accessible.
How Does a Septic Tank Work?
Septic tanks function by allowing wastewater to rest and settle, which is a natural process. In a septic system, solid particles and sediment settle to the bottom, where they may be separated from the water. Bacteria eat away at the sludge over time, transforming it into more manageable components for human use. This also causes scum to be released, such as fats, greases, and oil. Scum rises to the surface of the water and collects there. Following the filtration of the sediments, the filtered liquid wastewater, also known as “effluent,” is discharged via perforated pipes.
The water is channeled via these outlet pipes and into what is known as the drain field or leach field.
Finally, the wastewater percolates into our soil, where it is able to free itself of any harmful substances. This contains diseases that are potentially hazardous, such as coliform bacteria. In human excrement, coliform bacteria that are harmful to the body are detected.
Septic Tank Design
Tanks are available in a variety of shapes and sizes. Which one a home employs relies on elements such as the number of bedrooms, soil quality, lot size, and more. A septic system may be classified into several categories, according to the Environmental Protection Agency (EPA). The most prevalent of them are as follows:
Standard Septic Tank:
A single- or double-chamber tank that is buried beneath the surface of the earth.
Conventional Septic System:
Septic tanks that are connected to a soil or gravel drainfield provide a complete underground water treatment system.
Chamber Septic System:
A graveless septic tank system that employs linked subterranean chambers rather than an open drainfield instead of a traditional drainfield.
Drip Distribution System:
A shallow septic system that disperses sewage slowly using drip tubing.
Aerobic Treatment Unit (ATU):
These devices operate in the same way as a tiny sewage treatment plant, utilizing oxygen to stimulate natural bacterial activity in order to treat the waste.
Mound Septic System:
Whenever it is impossible to bury a drainfield, for example, in places with shallow soil or high groundwater, this method employs elevated trenches to safely guide wastewater flow to a treatment facility.
Recirculating Sand Filter System:
Effluent from a tank is sent to a pump chamber, where it percolates through a sand filter before being released. Depending on the use, it can be put above or below ground. In the absence of a filter, all of the waste particles will be able to pass through simply and clog up your plumbing.
Instead of filtering wastewater through the soil, this method traps it in the drainfield using a waterproof substance, allowing it to evaporate while the system is in operation.
Constructed Wetland System:
As opposed to the traditional method of filtering wastewater through the soil, this technique retains it in the drainfield using a waterproof substance, allowing it to evaporate.
Community Septic System:
It is not uncommon for housing sites near together to have septic tanks that drain into a common drainfield.
Inside a Septic Tank
The most common configuration consists of a septic tank, a distribution box, a drain field, and a network of perforated pipes that connects the first and second tanks. There is a single main drainage pipe, also known as an input pipe, that connects the septic tank and the home. The water waste from your home passes through it and into the septic tank, where it is divided into solid and liquid waste. Nowadays, the majority of septic tanks are divided into two parts. This essentially drives wastewater through two independent treatment cycles, resulting in a more efficient removal of the scum layer before the water is discharged to the drainfield.
- A tiny baffle permits liquid waste water to flow in just one direction when it is discharged.
- The Treatment of Septic Systems is a lengthy process.
- This is done in order to keep them out of the wastewater once it reaches the drainfield.
- There is a healthy population of anaerobic bacteria in the soil underneath the septic tank, and these bacteria feed on and digest the organic waste.
- Sludge and scum are prevented from exiting the septic tank and entering the drainfield by an outlet baffle at the other end of the system.
- The drainfield is a shallow area of open ground near the home that filters untreated wastewater via rocks, mud, and sand in order to eliminate contaminants in a natural and environmentally friendly manner.
- A good septic system is one that is hidden underneath and not visible.
Over each baffle, there are normally inspection openings, and most septic tanks also include a manhole access port, which enables for the pumping of the tank to take place. These access points are normally protected by a plastic cap with a diameter of approximately 4″.
What Does a Septic Tank Look Like?
From the exterior, an underground septic tank is typically characterized by the appearance of a huge metal or plastic box. These septic systems may typically be distinguished by the characteristic inspection pipes located on top of the box, which are often covered with green covers. The majority of tanks are equipped with one or two inspection pipes as well as bigger manhole covers for pumping. A vent pipe is used to expel the gases that have accumulated. Above-ground septic tanks have a distinctive appearance that distinguishes them from their underground counterparts.
Aside from that, they are often constructed of fiberglass, polymers, or some other weather-resistant material.
Attached to the outflow is a network of tiny, perforated pipes extending into the drainfield’s soil.
This will be determined by your daily water use as well as the number of bedrooms in your home.
What Does a Septic Tank Do?
Designed to remove sediments and pollutants from water, septic tanks are often used in residential and commercial settings. Understanding what a septic tank accomplishes will help you better understand how to care for your septic system in the future. The majority of conventional septic tank systems consist of a septic tank, which is often a large, hidden rectangular or cylindrical vessel composed of cement, fiberglass, or polyethylene material. It is not uncommon for septic systems built before 1975 to have a single compartment and for those built after 1975 to have many compartments, according to industry standards.
Sewage from all plumbing connections is directed toward the septic tank, where heavy masses fall to the lowest point and bacterial activity produces digested slime and fumes as a result of the digestion process.
Septic Tank Clean Out: Don’t Abuse the System
It is necessary to clean your septic system on a regular basis in order to keep it in good working order. If you don’t, your drains may become blocked, you may notice smells, and your drain field may become backed up with water. Septic tank pumping should only be required every two to three years in a well functioning system. When you have your tank pumped, it eliminates sediments, which enhances the flow and efficiency of the wastewater treatment process overall. If you don’t know what you’re doing when performing system maintenance, it’s possible to cause damage to the system.
We recommend that you have your septic tank cleaned by a professional. This will assist you in ensuring that your septic tank is working at peak performance and will prevent toxins from accumulating in the system over time.
Inadvertently adding chemical and biological additives is one of the most typical maintenance blunders. There are several flushable pills on the market that claim to improve the performance of your septic system by speeding up the breakdown processing and adding extra bacteria. With these substances, you will be able to cope with septic system failure more effectively. These have the potential to disrupt the delicate natural equilibrium in your tank. When septic systems are flushed out too quickly, it can have an adverse effect on the bacteria’s ability to operate properly.
During normal septic tank maintenance, it’s not only the tank that has to be taken into consideration; the drainfield is just as vital.
Avoid driving on the drainfield as much as possible since this might compress the soil and cause the effluent flow to become obstructed.
Don’t Overload the Septic System
When using a septic system, there are several things that should not be flushed down the drain. Organic waste and septic-safe tissue are the two types of waste that septic tanks can manage. The following are examples of things that might overflow your septic system:
- Toilet paper
- Diapers and sanitary goods
- Disposable wipes
- Paint and chemicals
- Cat litter
- Coffee grinds
- Fabric and apparel.
It’s always a good idea to double-check that anything is septic-safe before flushing it down the toilet. Though most toilet paper is septic safe, biodegradable toilet paper is preferred in order to avoid disturbing the important microorganisms. A clogged toilet or sewage forcing its way up through the leach field are all possible consequences of overburdening your system.

Every two to three years, it is a good idea to have your septic tank inspected. This will be done by a professional during normal pumping. If, on the other hand, you detect indicators that your septic system is malfunctioning, you should schedule an inspection as soon as possible. A faulty system might result in untreated garbage being transported to locations where it does not belong. While it’s vital to understand how a septic tank works, homeowners should always seek expert assistance if they have any problems with their system.
A basic home inspection will often only give the septic tank a cursory scan, so it’s advisable to contact a professional to examine the system thoroughly before making a decision on whether or not to purchase a home.
