Do modern septic tanks need to be emptied?
As a general rule, you should only need to empty your septic tank once every three to five years. A septic tank that is not working properly can pose serious problems for your home, including sewage back up in the drains in your home, or sewage bubbling up from the ground around your tank outside.
How do modern septic tanks work?
Septic tanks work by allowing solids to settle in the bottom of the tank and the liquid to drain out. Multiple chambers make the separation of solids and liquids more effective, with separating out more liquid with each chamber the flow moves through.
How a conventional septic system works?
In a conventional septic system, the majority of treatment occurs in the drainfield. Waste water flows from the tank through a solid pipe into a distribution box, where it is then channeled into perforated pipes set in trenches of gravel. The water slowly seeps into the underlying soil in the drainfield.
What are the new rules for septic tanks in 2020?
Under the new rules, if you have a specific septic tank that discharges to surface water (river, stream, ditch, etc.) you are required to upgrade or replace your septic tank treatment system to a full sewage treatment plant by 2020, or when you sell a property, if it’s prior to this date.
What happens if you never pump your septic tank?
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.
Are septic tanks always full of water?
A septic tank should always be “filled” to its normal liquid level, or the bottom of the outlet pipe which carries effluent to the absorption area. This normal liquid level is usually between 8” to 12” from the top of the tank on average (see picture at right).
Do all septic tanks have a soakaway?
A soakaway is not usually needed with a sewage treatment plant, but it is required with a septic tank. This is because the water released by a septic tank is primary treated effluent, meaning it has only gone through one stage of treatment.
Do you need to pump both sides of a septic tank?
Septic tanks installed after the late 1980s have two compartments, and it is important to pump out both compartments each time. Most homeowners are unaware when their septic tank has two compartments; some companies use that to their advantage, charging to pump both sides of the tank but only actually pumping out one.
How do septic tanks and field lines work?
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.
Do all septic tanks have filters?
First, not all septic tanks have a filter, especially the older septic tanks. Now many government agencies require or recommend a filter when a septic tank is installed. Cleaning a septic tank filter is different than pumping out a septic tank and cleaning it.
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.
What is the difference between conventional and engineered septic?
An engineered septic system is often used in cases where a conventional septic system cannot be installed. The local health department may require an engineered septic system when the soil or ground water conditions are not ideal. They can also be required when the field is located uphill from the home.
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.
Can you have a septic tank without a leach field?
The waste from most septic tanks flows to a soakaway system or a drainage field. If your septic tank doesn’t have a drainage field or soakaway system, the waste water will instead flow through a sealed pipe and empty straight into a ditch or a local water course.
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 decompose garbage, resulting in water that is clean enough to safely trickle down into the earth’s surface. 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 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.
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
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.
Meet the Expert
Septic systems, according to Jim vonMeier, are the solution to America’s water deficit because they supply cleaned water to depleted aquifers, according to vonMeier. He travels the country lobbying for septic systems, giving lectures, and giving testimony. For septic system inquiries, as well as information on the operation of the septic tank, contact him by email.
How Your Septic System Works
Underground wastewater treatment facilities, known as septic systems, are often employed in rural regions where there are no centralized sewage lines. They clean wastewater from residential plumbing, such as that produced by bathrooms, kitchen drains, and laundry, by combining natural processes with well-established technology. A conventional septic system is comprised of two components: a septic tank and a drainfield, often known as a soil absorption field. It is the septic tank’s job to decompose organic matter and to remove floatable stuff (such as oils and grease) and solids from wastewater.
Alternate treatment systems rely on pumps or gravity to assist septic tank effluent in trickling through a variety of media such as sand, organic matter (e.g., peat and sawdust), constructed wetlands, or other media to remove or neutralize pollutants such as pathogens that cause disease, nitrogen, phosphorus, and other contaminants.
Prior to discharging wastewater into the environment, several alternative systems are designed to evaporate or disinfect the effluent.
Specifically, this is how a typical conventional septic system works:
- All of the water that leaves your home drains down a single main drainage pipe and into a septic tank. An underground, water-tight container, often composed of concrete, fiberglass, or polyethylene, serves as a septic system’s holding tank. Its function is to retain wastewater for a long enough period of time to allow particles to sink to the bottom and form sludge, while oil and grease float to the surface and produce scum. Sludge and scum are prevented from exiting the tank and moving into the drainfield region by compartments and a T-shaped outlet. After that, the liquid wastewater (effluent) exits the tank and flows into the drainfield. The drainfield is a shallow, covered hole dug in unsaturated soil that serves as a drainage system. Porous surfaces are used to release pretreated wastewater because they allow the wastewater to pass through the soil and into the groundwater. In the process of percolating through the soil, wastewater is accepted, treated, and dispersed by the soil, finally discharging into groundwater. Finally, if the drainfield becomes overburdened with too much liquid, it can flood, causing sewage to flow to the ground surface or resulting in toilet backups and sink backups. Finally, wastewater percolates into the soil, where it is naturally removed of harmful coliform bacteria, viruses, and nutrients. Coliform bacteria are a kind of bacteria that may be found in the intestines of humans and other warm-blooded animals, with humans being the most common host. As a result of human fecal contamination, it is a sign of this.
The Guadalupe-Blanco River Authority has built an animated, interactive model of how a residential septic system works, which you can view here.
Do you have a septic system?
It’s possible that you’re already aware that you have a septic system. If you are not sure, here are some tell-tale symptoms that you most likely are:
- You make use of well water. In your home, the water pipe that brings water into the house does not have a meter. In the case of a water bill or a property tax bill, you will see “$0.00 Sewer Amount Charged.” It is possible that your neighbors have a septic system
How to find your septic system
You can locate your septic system once you have confirmed that you have one by following these steps:
- Taking a look at the “as constructed” drawing of your house
- Making a visual inspection of your yard for lids and manhole covers
- Getting in touch with a septic system service provider for assistance in locating it
Failure symptoms: Mind the signs!
A bad odor is not necessarily the first indicator of a septic system that is failing to work properly. Any of the following signs should prompt you to seek expert assistance:
- Water backing up into the drains of homes and businesses
- It is especially noticeable in dry weather that the drainfield grass is bright green and spongy. The presence of standing water or muddy soil near your septic system or in your basement
- A strong stench emanating from the area surrounding the septic tank and drainfield
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.
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.
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.
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.
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.
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.
Septic System Guide: How It Works and How to Maintain It
As soon as you flush the toilet in most metropolitan locations, the waste is pumped out to the nearest sewage treatment facility. Garbage is processed at this factory, which separates it into two types of waste: water that is clean enough to be dumped into a river and solids known as residual waste. The remaining material is either disposed of in landfill or utilized as fertilizer. Septic systems, which are used in places where there aren’t any sewage treatment plants, provide a similar function, but on a much smaller scale.
What are Septic Tanks and How Do They Work?
Septic tanks are normally composed of concrete or heavyweight plastic and have a capacity of 1000 to 2000 gallons, depending on the manufacturer. In the tank, there are two chambers that are divided by a portion of a wall. The waste from the residence is channeled into the bigger room. Solids sink to the bottom of the chamber, and liquids make their way through a partial wall into the smaller second chamber, which is located above it.
Anaerobic bacteria, which are found naturally in the environment, digest the solids and convert them into water, carbon dioxide, and a tiny amount of indigestible debris.
Septic Fields Distribute Liquid Effluent
The second chamber has an output pipe via which the liquid (known as effluent) from the tank is discharged to a disposal or leach field, depending on the situation. It is drained into the earth by a network of perforated pipes or through perforated plastic structures known as galleries, which are constructed of perforated plastic. It is common practice to lay the pipe or galleries in a bed of gravel, which aids in dispersing the liquid. During the course of the effluent’s percolation through the soil, the soil absorbs remaining bacteria and particles, resulting in water that is safe to drink by the time the water reaches the aquifer deeper down.
- They are not much deeper than that since a large quantity of water escapes through evaporation or is transpired by grass growing above ground.
- If you have sandy soils that drain too rapidly, you may not be able to treat the wastewater properly.
- Sometimes the water cannot be disposed of properly because the natural soils include a high concentration of silt or clay.
- Topsoil and grass are applied to the mound, which allows more water to leave through transpiration and evaporation than would otherwise be possible.
Septic Systems Rely on Gravity, Most of the Time
The majority of septic systems rely on gravity to transfer the liquid from the home to the tank and then to the field where it will be disposed of. However, due to the slope of the land, the tank or the field may need to be higher than the house in some instances. It is necessary to have a pump, or occasionally two pumps, in order for this to operate. A grinder pump, which liquefies sediments and is installed in a pit in the basement or crawlspace of the home, will be used if the tank is higher than the house.
Sewage pumps are essentially large sump pumps that are used for heavy-duty applications.
How to Treat Your Septic System
It is not necessary to do much to keep your septic system in good working order, other than cut the grass above it and keep the drainage area free of trees and plants with roots that may block it.
How Often Do You Need to Pump A Septic Tank?
You should have a septic provider pump out the particles from your tank every two years, at the absolute least. A manhole at the surface of the tank will provide the pump operator access, but older systems may necessitate digging a hole in the tank’s top so the pumping hatch can be exposed. Unless the tank is continuously pumped, sediments will build up in it and ultimately make their way into the leach field, clogging it. You’ll know it’s occurring because untreated effluent will rise to the surface of the tank and back up into the home, causing it to overflow.
It may be necessary to replace the entire field as a result of this. Pumping the tank on a regular basis can ensure that the leach fields continue to work eternally.
What to Do if Your Septic System Fails
Pumps in a pumped septic system will ultimately fail, just as they will in any mechanical system. Most pumps are equipped with an alarm that sounds when the effluent level in the pit is greater than it should be, indicating that the pump has failed and has to be replaced. This is a job that should be left to the professionals. Visit the following website to locate a trusted list of installation and septic system service companies in your area:

It is rare for a homeowner to have to worry about their septic system because it is well-maintained and doesn’t cause problems. Simple maintenance, such as keeping the tank pumped and the lawn trimmed, should result in decades of trouble-free service.

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 locations where there are no municipal sewage systems, each residence is responsible for treating its own sewage on its own property, which is known as a “on-site sewage disposal system,” or septic system, more popularly.
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. Many contemporary tanks are designed with two chambers in order to maximize efficiency. Household wastewater is collected in the septic tank, where it is separated and begins to degrade before being discharged into the leach field.
- In the tank, oil and grease float to the top of the tank, where they are known as scum, while solid waste falls to the bottom, where they are known as sludge.
- Bacteria and other microorganisms feed on the sediments at the bottom of the tank, causing them to decompose in an anaerobic (without oxygen) process that begins at the bottom of the tank.
- Solids and grease must be pushed out of the system on a regular basis in order for it to continue to function effectively.
- Each gallon added to the tank results in one gallon being discharged to the leach field, leach pit, or other similar treatment facility.
A large amount of water delivered too rapidly to the tank may discharge untreated effluent, along with oil and particulates, into the leach field, where it may block the field and cause a backup.
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.
- 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.
These systems sometimes cost twice or three times as much as a regular system and require significantly more upkeep. Near flood plains, bodies of water, and other ecologically sensitive places, special systems may also be necessary to protect people and property.
SEPTIC SYSTEM CAREMAINTENANCE REQUIRED
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.
- 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.
In addition, refrain from flushing sediments, strong chemicals, and just about anything else down the toilet or sink other than biological waste and white toilet paper. Avoid 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 destroy beneficial microorganisms or cause water contamination 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. After a few tears, the initial field will naturally heal and may be used once again when the situation calls for it to be. More information on Septic System Maintenance may be found here.
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 situations that might cause a septic system to operate poorly: Plumbing in the home. obstructed or insufficient plumbing vents, a blockage between the home and the septic tank, or an insufficient pitch in the sewer line 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.

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 be sure that anything you put into your tank and septic field is causing the least amount of ground contamination 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 bigger septic tank with only a couple of people living in your house, for example, will not require pumping as frequently as a smaller septic tank or as a septic tank that must manage the waste products of multiple 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.

Food scraps can enhance the amounts of nitrogen and phosphorus in the wastewater, which can disturb the natural bacterial balance of the septic tank, among other things.
Water conservation should be practiced.
Exceedingly large amounts of water use will interfere with the normal flow of wastewater from your home into your septic tank.
Limiting the amount of time you spend in the shower and turning off the faucet while brushing your teeth, as well as purchasing a smaller dishwasher and washing machine that use less water, are all simple strategies to reduce water use in your home.
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.
The 6 Septic Systems You Must Know — Build With a Bang
Unacquainted with the many types of septic systems available? If this is the case, you are not alone. Unless your property is directly linked to the sewer system, you most certainly have a septic system in place. Sewage treatment on site is accomplished by the use of natural processes in a septic system, which is a linked system of components residing under ground. Typically, a septic system is located in the yard of a homeowner. The most typical location for septic systems is in rural locations, where there is no access to a centralized town or city waste treatment facility or sewage treatment system.
Why Concrete Septic Tanks May Be Your Best Option
First and foremost, the septic system collects and dumps the waste generated by the home in the septic tank. The septic tank then separates and pre-treats the solid waste and oils from the wastewater before releasing them into the environment. Following that, most systems direct liquid wastewater from the septic tank onto a distribution network of porous pipes that branch out from the residence and septic tank and gradually discharge the wastewater into the soil. Some septic systems, rather than just discharging wastewater into the soil, employ pumps, disinfection products, an evaporation mechanism, or simply rely on gravity to funnel wastewater through sand or other organic material before releasing the effluent into the soil.
- The total square feet of drain field area required is determined by the number of bedrooms in the house and the soil type (arid or saturated), among other factors.
- Septic tanks are intended to serve as the initial stop in the wastewater treatment process, and they are constructed to do so.
- The sediments remain in the tank, while the wastewater is sent to the drain field for further treatment and dispersal when it has been treated.
- Concrete, plastic (polyethylene), and fiberglass are the three most common materials used in construction.
- Drain fields are plots of land that have been particularly engineered to assist in the filtering and removal of pollutants from wastewater.
Perforated pipes, which are buried within the trenches, are used to disseminate the wastewater from the home in a methodical manner. A standard septic system is comprised of a septic drain field, its associated pipe system, and a septic tank.
The majority of traditional septic systems are situated in single-family residences or small commercial establishments. A high number of individuals in a single area is not often served by traditional systems, which are not normally designed for this purpose. A typical system consists of the following components: Sewage treatment system (Septic tank) An underground wastewater infiltration system or a gravel-filled drain field can both be used to collect wastewater. Protects the clean drain field from additional possible impurities with a strong geofabric covering.
The wastewater (also known as effluent) is routed from the septic tank to the drain field in this location.
As soon as the wastewater passes through the clean drain field, it flows into the soil where it is continuously cleaned by naturally existing bacteria as it gently trickles its way through the soil layer and into groundwater.
The disadvantage is that it is difficult to install in homes with small lots.
As a viable alternative to the more frequent gravel field technique, chamber systems have been in use since the 1970s. It is common to employ chamber systems in places where the water table is high, as they reduce the likelihood of poor drainage and messy back-ups. Another need for this system is a sequence of linked pipelines and chambers, with the chambers being completely enclosed by soil. The septic pipes transport wastewater from the home to the septic tank, which subsequently transports the wastewater to the chambers.
During the last stages of wastewater treatment before it is discharged into a storm drain, bacteria in the soil release the treated wastewater into the soil as it flows downward toward the groundwater table.
The disadvantage of using an extra chamber instead of a more standard drain field is that there is an increased risk of additional maintenance.
Aerobic Treatment System
Aeration of wastewater in a septic treatment tank is accomplished by the use of aerobic treatment equipment. The infused oxygen in the wastewater aids in the addition of nutrients to the wastewater as well as the efficient start of the treatment process itself. Aerobic systems are available with tanks that may be used for both pretreatment and final treatment, as well as systems with two distinct tanks for pretreatment and final treatment, among other options. The ultimate objective is to treat and disinfect in a safe and efficient manner, without causing harm.
Advantage: This is particularly useful in locations with high water tables or in areas where there is insufficient land to construct a good drain field. The disadvantage of using an aerobic system is that, like the drip distribution system, it requires regular maintenance.
Drip Distribution System
It is not necessary to install a standard gravel-based drain field since the Drip Distribution system makes use of an underground snaking system of distribution pipes that are installed near the surface of the soil. Pipe laterals for the drip distribution system are buried in shallow ground soil, generally 6 to 12 inches below the surface of the ground. Because it eliminates the requirement for a standard drain field, this technique reduces the amount of digging required and makes it easier to reach plumbing within the drain field.
A second tank, referred to as a dosage tank, is required to take wastewater after it has passed through the septic tank in order to handle this technique.
However, in order for this to happen, the dosage tank must be connected to power.
Sand Filter System
Sand filter systems allow waste water to travel from a septic tank to a pump chamber, and then from the pump chamber to the sand filtering system. Sand filter systems are used in conjunction with septic tanks. The sand filtration system is essentially a big concrete box that is filled with sand to filter out contaminants. Following a leisurely pumping operation to the top of the box, the waste water is filtered through the sand, which treats the water prior to its discharge into the soil absorption region (see illustration).
Cons: Frequent maintenance is required.
In contrast to conventional septic systems, the Evapotranspiration System’s drain field is housed in a closed, waterproof field that is covered with layers of gravel and sand to keep out the elements. Once the wastewater has passed through the septic tank and into the waterproof drain field, it begins to evaporate slowly. It is important to note that, unlike other septic systems, the effluent never filters into the soil. When compared to the alternatives, the ease of installation, maintenance, and use is superior.
Benefits: The ease of use is excellent, and the difficulty of installation and maintenance is minimal.
The mound system consists of the construction of a big sand mound that serves as a drain field. A controlled flow of wastewater is maintained throughout its journey from the septic tank to a chamber where it is pushed through to the mound. After flowing through a mound trench and percolating through the sand, the wastewater eventually trickles into the ground. Among those who live in rural locations where there is a lot of land but little absorbent soil, the mound system is a popular alternative.
Cons: It takes up a lot of room and requires a lot of upkeep.
In any case, count on having your septic tank examined once per year and pumping it at least once every six months, regardless of the system you have in place. Solid waste matter can block the pump and cause damage to the drain field if it is not pumped on a regular basis.
Garbage Disposal With Septic
Unless you reside in a septic-equipped home, it is better not to have a trash disposal. The increased volume of solid waste material will necessitate more frequent septic tank pumping and may erode the drain field, resulting in sewage back-ups in the future. Those who live in homes with septic systems may find that they must be extra cautious about what they flush down the toilet. Certain common home objects, when flushed down a toilet connected to a septic system, can create clogs, backups, and even damage to the system, resulting in not only discomfort and aggravation, but also a significant financial burden.
Chemicals may cause significant damage to and contamination of surface and groundwater, which can result in disease or even death in animals and people who consume the water.
