What In A Septic Tank? (Solved) - THE Greywater Guide

The septic tank is a buried, water-tight container usually made of concrete, fiberglass, or polyethylene. Its job is to hold the wastewater long enough to allow solids to settle down to the bottom forming sludge, while the oil and grease floats to the top as scum.

What waste goes into a septic tank?

A septic tank will take the wastewater from your property’s toilets, sinks, baths and showers, dishwashers and washing machines. The waste water leaves your property through the drainage pipes to your septic tank, and will usually pass through a number of inspection chambers or manholes.

What happens inside a septic tank?

Septic tanks work by allowing waste to separate into three layers: solids, effluent and scum (see illustration above). The solids settle to the bottom, where microorganisms decompose them. The middle layer of effluent exits the tank and travels through underground perforated pipes into the drainage field.

What happens to sewage in septic tank?

The inlet pipe collects the water waste in the septic tank, long enough that the solid and liquid waste is separated from each other. Inside the tank bacteria from the wastewater breaks down the solid waste. These bacteria decompose the solid waste rapidly allowing the liquids to separate and drain away more easily.

What are the three basic parts of a septic tank?

Septic tank – Household waste receives primary treatment in the septic tank, an anaerobic environment, and separates into 3 layers; a sludge layer, a clear zone, and a scum layer.

Can I take a shower if my septic tank is full?

Only the water would get out into the leach field in a proper system unless you run too much water too fast. The thing to do is to run your shower water outside into it’s own drain area, but it may not be allowed where you are. Used to be called gray water system.

How do you know your septic tank is full?

Here are some of the most common warning signs that you have a full septic tank:

Your Drains Are Taking Forever.

Standing Water Over Your Septic Tank.
Bad Smells Coming From Your Yard.
You Hear Gurgling Water.

You Have A Sewage Backup.
How often should you empty your septic tank?

Can a septic tank never be pumped?

What Are the Consequences of Not Pumping Your Tank? If the tank is not pumped, the solids will build up in the tank and the holding capacity of the tank will be diminished. Eventually, the solids will reach the pipe that feeds into the drain field, causing a clog. Waste water backing up into the house.

How long do septic tanks last?

A septic system’s lifespan should be anywhere from 15 to 40 years. How long the system lasts depends on a number of factors, including construction material, soil acidity, water table, maintenance practices, and several others.

How do they empty a septic tank?

Generally, commercial septic pumping involves a pump truck removing the sludge, effluent and scum in the tank and leaving the tank empty and ready to be filled again. Prior to federal laws that restrict septic sludge dumping, waste companies could simply bury it in dump sites.

Does poop float in septic tank?

The American diet is often high in fats (which cause feces to float in a septic tank), or high in iron-rich meat (which blackens your stool and causes it to sink like torpedo). Neither of these is good for your septic tank, but you can change that by changing your lifestyle and eating habits.

What can break down poop in septic tank?

Yeast helps actively breaks down waste solids when added to your septic system. Flush ½ cup of dry baking yeast down the toilet, the first time. Add ¼ cup of instant yeast every 4 months, after the initial addition.

Where does poop go after septic tank?

After the waste is filtered, it moves into a sand container, where sand, ashes, and gravel settle at the bottom of the container. The gravity pull allows sewage to run through the pipes of each structure and sends the waste material to a sewer line that flows into larger vessels to the sewage treatment plant.

What are the five main parts to a septic system?

What are the two main components of a septic system?

A typical septic system consists of a septic tank and a drainfield, or soil absorption field. The septic tank digests organic matter and separates floatable matter (e.g., oils and grease) and solids from the wastewater.

What size pipe goes into septic tank?

Four-inch pipe is standard, and it should extend far enough under the house to connect with the main soil stack, which is a 3-inch pipe that extends vertically past the main bathroom and through the roof.

Types of Septic Systems

Septic system design and size can differ significantly from one neighborhood to the next, as well as throughout the country, due to a variety of variables. Household size, soil type, slope of the site, lot size, closeness to sensitive water bodies, weather conditions, and even municipal ordinances are all considerations to take into consideration. The following are 10 of the most often encountered septic system configurations. It should be noted that this is not an exhaustive list; there are several additional types of septic systems.

Septic Tank, Conventional System, Chamber System, Drip Distribution System, Aerobic Treatment Unit, Mound Systems, Recirculating Sand Filter System, Evapotranspiration System, Constructed Wetland System, Cluster / Community System, etc.

Septic Tank

This tank is underground and waterproof, and it was designed and built specifically for receiving and partially treating raw home sanitary wastewater. Generally speaking, heavy materials settle at or near the bottom of the tank, whereas greases and lighter solids float to the surface. The sediments are retained in the tank, while the wastewater is sent to the drainfield for further treatment and dispersion once it has been treated.

Conventional System

Septic tanks and trench or bed subsurface wastewater infiltration systems are two types of decentralized wastewater treatment systems (drainfield). When it comes to single-family homes and small businesses, a traditional septic system is the most common type of system. For decades, people have used a gravel/stone drainfield as a method of water drainage. The term is derived from the process of constructing the drainfield. A short underground trench made of stone or gravel collects wastewater from the septic tank in this configuration, which is commonly used.

Effluent filters through the stone and is further cleaned by microorganisms once it reaches the soil below the gravel/stone trench, which is located below the trench.

Chamber System

Gravelless drainfields have been regularly utilized in various states for more than 30 years and have evolved into a standard technology that has mostly replaced gravel systems. Various configurations are possible, including open-bottom chambers, pipe that has been clothed, and synthetic materials such as expanded polystyrene media. Gravelless systems can be constructed entirely of recycled materials, resulting in considerable reductions in carbon dioxide emissions during their lifetime. The chamber system is a type of gravelless system that can be used as an example.

The key advantage of the chamber system is the enhanced simplicity with which it can be delivered and built.

This sort of system is made up of a number of chambers that are connected to one another.

Wastewater is transported from the septic tank to the chambers through pipes. The wastewater comes into touch with the earth when it is contained within the chambers. The wastewater is treated by microbes that live on or near the soil.

Drip Distribution System

An effluent dispersal system such as the drip distribution system may be employed in a variety of drainfield configurations and is very versatile. In comparison to other distribution systems, the drip distribution system does not require a vast mound of dirt because the drip laterals are only placed into the top 6 to 12 inches of soil. In addition to requiring a big dosage tank after the sewage treatment plant to handle scheduled dose delivery of wastewater to drip absorption areas, the drip distribution system has one major disadvantage: it is more expensive.

Aerobic Treatment Unit

Aerobic Treatment Units (ATUs) are small-scale wastewater treatment facilities that employ many of the same procedures as a municipal sewage plant. An aerobic system adds oxygen to the treatment tank using a pump. When there is an increase in oxygen in the system, there is an increase in natural bacterial activity, which then offers extra treatment for nutrients in the effluent. It is possible that certain aerobic systems may additionally include a pretreatment tank as well as a final treatment tank that will include disinfection in order to further lower pathogen levels.

ATUs should be maintained on a regular basis during their service life.

Mound Systems

Using mound systems in regions with short soil depth, high groundwater levels, or shallow bedrock might be a good alternative. A drainfield trench has been dug through the sand mound that was erected. The effluent from the septic tank runs into a pump chamber, where it is pumped to the mound in the amounts recommended. During its release to the trench, the effluent filters through the sand and is dispersed into the native soil, where it continues to be treated. However, while mound systems can be an effective solution for some soil conditions, they demand a significant amount of land and require regular care.

Recirculating Sand Filter System

Sand filter systems can be built either above or below ground, depending on the use. The effluent is discharged from the septic tank into a pump compartment. Afterwards, it is pushed into the sand filter. The sand filter is often made of PVC or a concrete box that is filled with a sand-like substance. The effluent is pushed through the pipes at the top of the filter under low pressure to the drain. As the effluent exits the pipelines, it is treated as it passes through the sand filtering system.

However, sand filters are more costly than a standard septic system because they provide a higher level of nutrient treatment and are thus better suited for areas with high water tables or that are adjacent to bodies of water.

Evapotranspiration System

Evaporative cooling systems feature drainfields that are one-of-a-kind. It is necessary to line the drainfield at the base of the evapotranspiration system with a waterproof material. Following the entry of the effluent into the drainfield, it evaporates into the atmosphere. At the same time, the sewage never filters into the soil and never enters groundwater, unlike other septic system designs. It is only in particular climatic circumstances that evapotranspiration systems are effective. The environment must be desert, with plenty of heat and sunshine, and no precipitation.

Constructed Wetland System

Construction of a manufactured wetland is intended to simulate the treatment processes that occur in natural wetland areas. Wastewater goes from the septic tank and into the wetland cell, where it is treated. Afterwards, the wastewater goes into the media, where it is cleaned by microorganisms, plants, and other media that eliminate pathogens and nutrients. Typically, a wetland cell is constructed with an impermeable liner, gravel and sand fill, and the necessary wetland plants, all of which must be capable of withstanding the constant saturation of the surrounding environment.

As wastewater travels through the wetland, it may escape the wetland and flow onto a drainfield, where it will undergo more wastewater treatment before being absorbed into the soil by bacteria.

Cluster / Community System

In certain cases, a decentralized wastewater treatment system is owned by a group of people and is responsible for collecting wastewater from two or more residences or buildings and transporting it to a treatment and dispersal system placed on a suitable location near the dwellings or buildings. Cluster systems are widespread in settings like rural subdivisions, where they may be found in large numbers.

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 cleanse waste water through the processes of biological breakdown 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 waterproof container (usually rectangular or spherical) that is buried underground and made of fiber 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.

In some cases, if a drain field becomes overwhelmed with too much liquid, it might flood, which can result in sewage flowing to the ground surface or creating backups in toilets and sinks.

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.

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.

Septic System Basics

When a household isn’t connected to a public sewage system, it normally relies on septic systems to treat and dispose of wastewater. Sewage treatment systems require a substantial financial commitment. The correct maintenance and upkeep of a well-designed, installed, and maintained system will provide years of dependable and low-cost service. The failure of a system can become a source of pollution and public health concern, resulting in property damage, ground and surfacewater pollution (such as contamination of well water used by you and your neighbors), and the spread of disease.

Aside from that, if you are planning to sell your property, your septic system has to be in good functioning order.

Septic systems are available in a variety of configurations to accommodate a wide range of soil and site conditions.

Understanding the major components of a typical (gravity-fed) septic system, as well as how to maintain it working properly and at the lowest possible cost, can help you make the best decision possible. A conventional septic tank system is composed of three major components:

This is known as the Septic Tank. In order to remove particles from wastewater, store and partially decompose as much solid material as possible, while allowing the liquid (or effluent) to flow to the drainfield, a septic tank must be installed. more
The Drainage System After the particles have settled in the septic tank, the liquid wastewater (also known as effluent) is released to the drainfield, which is also known as an absorption or leach field, or both. more

The Soil is a very important factor. The soil under the drainfield is responsible for the ultimate treatment and disposal of the septic tank effluent once it has been treated. Following the passage of wastewater into the soil, organisms in the soil remediate the effluent before it percolates downward and outward, eventually entering ground or surface water sources. A drainfield’s efficacy is also affected by the kind of soil
For example, clay soils may be too tight to allow much wastewater to run through, while gravelly soil may be too coarse to give much treatment.

Septic System Inspection Done at Home In order to aid you in examining your system, a VideoField Guide and Checklist may be available at the bottom of the homepage.

Homeowners and residents have a significant impact on the functioning of their septic systems. Overloading the system with more water than it is capable of handling might result in system failure. A septic system can also be damaged by the improper disposal of chemicals or excess organic waste, such as that produced by a trash disposal. The following maintenance suggestions might assist you in ensuring that your system provides long-term, effective treatment of domestic waste.

Inspect and Pump Frequently

The most critical step in keeping your septic tank in good working order is to eliminate sludge and scum build-up before it may flow into the drainfield. The frequency with which your tank has to be pumped is determined by the size of the tank, the number of people in your family, the quantity of water utilized, and the amount of solids (from humans, garbage disposal, and any other waste) that enter the tank’s drainage system. Tanks should be pumped out on average every 3 to 5 years, depending on usage.

Septic Inspection and Pumping Guide

Inspecting Your Septic Tank
Septic Inspection and Pumping Guide

Use Water Efficiently

System failure is frequently caused by an excessive amount of water. The soil beneath the septic system must be able to absorb all of the water that is used in the residence. Too much water from the washing machine, dishwasher, toilets, bathtubs, and showers may not provide enough time for sludge and scum to separate properly in the drain. The less water that is consumed, the less water that enters the septic system, reducing the likelihood of system failure. For further information on water conservation, visit:

Every gallon of water conserved equates to a savings of $1.00.

Minimize Solid Waste Disposal

What you flush down the toilet can have a significant influence on the performance of your septic system. Many things do not breakdown properly, and as a result, they accumulate in your septic tank. If you have the option of disposing of it in another manner, do so rather than introducing it into your system.

Keep Chemicals Out of Your System

Protect your septic system against home chemicals such as caustic drain openers, paint and pesticides. Also avoid flushing down the toilet with chemicals such as brake fluid, gasoline, and motor oil. The improper dumping of dangerous substances down the drain is damaging to the environment, as well as the bacteria that are necessary for the breakdown of wastes in a septic system, and should be avoided.

Septic System Additives

It is not essential to add a stimulant or an enhancer to a septic tank in order to assist it in functioning or “to restore bacterial equilibrium.” The naturally occurring bacteria required for the proper operation of the septic system are already present in human excrement. Septic systems, like automobiles, are designed to offer long-term, effective treatment of residential waste if they are properly run and maintained on a regular basis. The majority of systems that fail prematurely, on the other hand, are the result of poor maintenance.

If you see any of the indicators listed below, or if you have reason to believe your septic system is experiencing issues, call a trained septic technician immediately. In the event that your septic system fails, call Thurston County Environmental Health at 360-867-2673 for assistance.

Odors, surface sewage, moist areas, or a dense growth of plants in the drainfield region are all possible problems. Backups from the plumbing or septic tank (which are often a dark liquid with a foul odor)
Fixtures that take a long time to drain
The plumbing system is making gurgling sounds. Your drainfield may be failing if you have a well and tests reveal the presence of coliform (bacteria) or nitrates in the water from it. Even in the midst of a drought, the drainfield is covered with lush green grass.

A Beginner’s Guide to Septic Systems

Septic systems are used to dispose of waste from homes and buildings. Identifying the location of the septic tank and drainfield
What a Septic System Is and How It Works Keeping a Septic System in Good Condition
Signs that a septic system is failing include:

Septic systems, also known as on-site wastewater management systems, are installed in a large number of buildings and houses. It is easy to lose sight of septic systems, which operate quietly, gracefully, and efficiently to protect human and environmental health due to their burying location. Septic systems are the norm in rural regions, but they may also be found in a lot of metropolitan places, especially in older buildings. It is critical to understand whether or not your building is on a septic system.

Is Your Home or Building on a Septic System?

It is possible that the solution to this question will not be evident. If a structure looks to be connected to a sewage system, it may instead be connected to a septic system. It is fairly unusual for tenants to be unaware of the final destination of the wastewater generated by their residence. Some of the hints or signs listed below will assist in determining whether the facility is served by a septic system or whether it is supplied by a sewer system:

Sewer service will be provided at a cost by the city or municipality. Pay close attention to the water bill to see whether there is a cost labeled “sewer” or “sewer charge” on it. If there is a fee for this service, it is most likely because the facility is connected to a sewage system. Look up and down the street for sewage access ports or manholes, which can be found in any location. If a sewage system runs in front of a property, it is probable that the house is connected to it in some way. Inquire with your neighbors to see if they are connected to a sewer or septic system. The likelihood that your home is on a sewer system is increased if the properties on each side of you are on one as well. Keep in mind, however, that even if a sewage line runs in front of the structure and the nearby residences are connected to a sewer system, your home or building may not be connected to one. If the structure is older than the sewer system, it is possible that it is still on the original septic system. Consult with your local health agency for further information. This agency conducts final inspections of septic systems to ensure that they comply with applicable laws and regulations. There is a possibility that they have an archived record and/or a map of the system and will supply this information upon request

All property owners should be aware of whether or not their property is equipped with an on-site wastewater treatment system. Georgia law mandates that the property owner is responsible for the correct operation of a septic system, as well as any necessary maintenance and repairs.

Locating the Septic Tank and Drainfield

Finding a septic system may be a difficult process. They can be buried anywhere in the yard, including the front, back, and side yards. After a few years, the soil may begin to resemble the surrounding soil, making it impossible to distinguish the system from the surrounding soil. It is possible that in dry weather, the grass will be dryer in the shallow soil over the tank and greener over the drainfield, where the cleansed water will be released, but this is not always the case, especially in hot weather.

The contractor who built the house should have presented the initial owner with a map showing the tank and drainfield locations, according to the building code.
The installation of the system, as well as any modifications made to it, would have been examined by your local health authority.
Unfortunately, if the system is very old, any records related with it may be insufficient or nonexistent, depending on the situation.

Look for the point at where the wastewater pipes join together if the building is on a crawlspace or has an unfinished basement.
The sewer line that runs through the structure is referred to as the building sewer.
To “feel” for the tank, use a piece of re-bar or a similar metal probe.

If you use this free service, you may avoid accidentally putting a rod through your gas or water line.

Try to locate the tank after a rainstorm, when the metal probe will be more easily maneuvered through moist dirt.

This should be done with care; extreme caution should be exercised to avoid puncturing the building sewer.

A tank is normally 5 by 8 feet in size, however the dimensions might vary.

Be aware that there may be rocks, pipes, and other debris in the area that “feels” like the tank but is not in fact part of the tank.

However, it is possible to have the lid or access port positioned on a riser in addition to being on the same level as the top of the tank in some cases.

Once the tank has been identified, make a rough drawing of its placement in relation to the house so that it will not be misplaced again!

It may be easier to discover the drainage lines now that the tank has been identified, particularly if the area has been subjected to prolonged periods of drought.

How a Septic System Works

Typical sewage treatment system (figure 1). It is composed of three components (Figure 1): the tank, the drain lines or discharge lines, and the soil treatment area (also known as the soil treatment area) (sometimes called a drainfield or leach field). The size of the tank varies according to the size of the structure. The normal home (three bedrooms, two bathrooms) will often include a 1,000-gallon water storage tank on the premises. Older tanks may only have one chamber, however newer tanks must have two chambers.

The tank functions by settling waste and allowing it to be digested by microbes.

These layers include the bottom sludge layer, the top scum layer, and a “clear” zone in the center.
A typical septic tank is seen in Figure 2.
It is fortunate that many of the bacteria involved are found in high concentrations in the human gastrointestinal tract.

Although the bacteria may break down some of the stuff in the sludge, they are unable to break down all of it, which is why septic tanks must be cleaned out every three to seven years.
In addition, when new water is introduced into the septic tank, an equal volume of water is pushed out the discharge lines and onto the drainfield.
The water trickles out of the perforated drain pipes, down through a layer of gravel, and into the soil below the surface (Figure 3).

A typical drainfield may be found here.
Plants, bacteria, fungus, protozoa, and other microorganisms, as well as bigger critters such as mites, earthworms, and insects, flourish in soil.
Mineralogical and metallic elements attach to soil particles, allowing them to be removed from the waste water.

Maintaining a Septic System

The most typical reason for a septic system to fail is a lack of proper maintenance. Septic systems that are failing are expensive to repair or replace, and the expense of repairs rests on the shoulders of the property owner (Figure 4). Fortunately, keeping your septic system in good working order and avoiding costly repairs is rather simple. Figure 4. Septic system failure is frequently caused by a lack of proper maintenance. It is in your best interests to be aware of the location of the system, how it operates, and how to maintain it.

You should pump the tank if you aren’t sure when the last time it was pumped.
It is not permissible to drive or park over the tank or drainage field.

No rubbish should be disposed of in the sink or the toilet.
It’s important to remember that garbage disposals enhance the requirement for regular pumping.
When designing a landscape, keep the septic system in mind.

It is also not recommended to consume veggies that have been cultivated above drainfield lines (see Dorn, S.
Ornamental Plantings on Septic Drainfields.

C 1030).

Any water that enters your home through a drain or toilet eventually ends up in your septic system.

Don’t put too much strain on the system by consuming a large amount of water in a short period of time.

Additives should not be used.

Various types of additives are available for purchase as treatment options, cleansers, restorers, rejuvenator and boosters, among other things.

To break up oil and grease and unclog drains, chemical additives are available for purchase.

Pumping out the septic tank is not eliminated or reduced by using one of these systems.

They remain floating in the water and travel into the drainfield, where they may block the pipes. Acids have the potential to damage concrete storage tanks and distribution boxes.

Signs a Septic System is Failing

A failed system manifests itself in the following ways:

Sinks and toilets drain at a snail’s pace
Plumbing that is backed up

The sound of gurgling emanating from the plumbing system House or yard aromas that smell like sewage
In the yard, there is wet or squishy dirt
Water that is gray in hue that has accumulated

An region of the yard where the grass is growing more quickly and is becoming greener
Water contaminated by bacteria from a well

If you notice any of these indicators, you should notify your local health department immediately. An environmentalist from the health department can assist in identifying possible hazards. There are also listings of state-certified contractors available from the local health department, who may do repairs. Repairs or alterations to the system must be approved by the health department and examined by an inspector. Keep an eye out for any meetings that may take place between a health department inspector and a contractor to discuss repairs to your system.

Household garbage that has not been properly handled is released into the environment when systems fail.
It has the potential to pollute surrounding wells, groundwater, streams, and other sources of potable water, among other things.
The foul odor emanating from a malfunctioning system can cause property values to plummet.

Briefly stated, broken systems can have an impact on your family, neighbors, community, and the environment.
Septic systems are an effective, attractive, and reasonably priced method of treating and disposing of wastewater.

How a Septic Tank System Works

The most popular form of septic system is composed of four major components:

A sewer exit pipe that transports wastewater from the residence to the septic tank while also venting noxious gases up and out of the house. Septic tank composed of concrete, fiberglass, or polyethylene that is underground and waterproof
It is typically put around 6 feet away from a house. It comprises of one or more distributor boxes and a network of pipes that are buried in relatively shallow trenches that are generally filled with gravel or other filler

The drainfield The soil, which contains microorganisms that digest the majority of toxins before they reach groundwater

How it Works

Household wastewater is flushed or cleansed through the exit pipe into the septic tank. Heavy solids sink to the bottom of the container. Over the course of 24-48 hours, the solids decompose and form a sludge layer. Lighter floatablesolids, such as grease, oils, and fats, gather at the top of the liquid in the tank to produce a scum layer. The bacteria that live in the septic tank constantly break down solid waste. The tank’s fittings hold the scum andsludge from flowing out into the drainfield.

In the tank, effluent is partially treated or”clarified” by bacteria.

The liquid drains through the soil layers, where bacteria filter and digest contaminants.

Additives

A claim made by companies that manufacture and sell biological additives is that their product restores the bacterial equilibrium of the septic tank and that doing so is important as part of a periodic monthly maintenance program.

However, because bacteria already exist in human feces, these additions are typically not required.

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

It is important to do regular “pumping” in order to eliminate waste and build-up in the tank, which helps to keep a septic system in good working order. Depending on the design and installation, a well-designed and professionally constructed septic system might endure for decades or fail in a matter of years. The decision is yours as long you are able to answer the question of how do septic systems tanks function.

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 usage of these goods, 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.

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

Following a comprehensive first check performed by an expert, regular inspections will cost less than $100 each inspection for the next year. Your professional will be able to inform you how often you should get your system inspected as well as how a septic tank functions. As straightforward as a septic system appears, determining its overall condition necessitates the services of a professional. There are a plethora of contractors who would gladly pump the sludge out of your tank, but many, in my experience, are unable to explain how a septic system works or how it should be maintained.

A certification scheme for septic contractors has been established in certain states; check with your state’s Secretary of State’s office to see whether yours is one of them.

Also, a qualified inspector will be able to tell you whether or not your tank is large enough to accommodate your household’s needs, as well as the maximum amount of water that can be passed through it in a single day.

As you learn more about how a septic tank works, your professional should be able to tell you whether or not your system will benefit from this treatment.

Alternatives to a new drain field

If an examination or a sewage backup indicate 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.

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.

These outlet pipes transport the water to a place known as the drainfield or leach field, depending on the region.

Finally, the wastewater percolates into our soil, where it is able to free itself of any harmful substances.

In human excrement, coliform bacteria that are harmful to the body can be discovered.

Septic Tank Design

Tanks are available in a variety of shapes and sizes.

Depending on the number of bedrooms, soil condition, lot size, and other considerations, a household will choose one over the other. A septic system may be classified into several categories, according to the Environmental Protection Agency (EPA). The most prevalent of them are as follows:

The term “standard septic tank” refers to a single or double-chamber tank that is located underground. a conventional septic system is a complete underground water treatment system in which the septic tank discharges onto a soil or gravel drainfield
And Septic tank system that does not require excavation and instead makes use of linked subsurface chambers rather than an open drainfield. Drip Distribution System: A shallow septic system that uses drip tubing to disseminate sewage gently
These devices operate similarly to a tiny sewage treatment plant, using oxygen to stimulate naturally occurring bacterial activity for the purpose of treatment. When it is impossible to bury a drainfield, such as in places with shallow soil or high groundwater, a mound septic system is used to properly route wastewater flow through elevated trenches. Pump-Chamber-Sand Filter System: This system circulates effluent from the tank to the pump chamber, where it percolates through the sand filter. Depending on the use, it can be put above or below ground. In the absence of a filter, all waste particles will be able to pass through easily and clog your pipes
Method of Evapotranspiration: Rather than filtering wastewater through the soil, this system traps it in the drainfield using a watertight membrane, allowing it to evaporate. Constructed Wetland System: This environmentally friendly system mimics natural water treatment processes by directing wastewater to a wetland cell rather than a drainfield for screening and treatment. The use of a community septic system might occur when many home sites are near together and the septic tanks flow 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 solid and liquid waste are separated from the liquid waste and disposed of separately. Nowadays, the majority of septic tanks are divided into two parts.

Both compartments are waterproof and are separated by a sturdy wall that prevents water from entering.

A T-shaped baffle, similar to the inlet and exit pipes, is used to prevent particles from entering.

The Septic System Treatment Process

When wastewater enters a treatment plant through an intake pipe, grease and oil float to the top of the water column, while solid waste and silt sink to the bottom. This is done in order to keep them out of the wastewater once it reaches the drainfield. Solids can clog the perforated pipes in the area, and oils can cause harm to the leached soil as they pass through. 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.
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.

A network of tiny, perforated pipes connected to the outflow and reaching into the drainfield’s soil is also present.

The size of this region is determined by the amount of water that your septic tank must handle. 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.

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.

Don’t Use Additives

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 the help of these substances, you will be able to cope with septic system failure. These have the potential to disrupt the delicate natural equilibrium in your tank.

Don’t Flush the System

When septic systems are flushed out too quickly, it can have an adverse effect on the bacteria that live there. It can also cause scum and sediments to be disturbed, increasing the likelihood that they will clog up system components.

Take Care of the Drainfield

During normal septic tank maintenance, it’s not only the tank that has to be taken into consideration; the drainfield is just as vital. It is not recommended that you construct a structure or plant anything with deep roots in the region. 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.
