- Septic tank field lines are also called drain field lines. These extend outward from the septic tank. The exit baffle is connected to a drain field pipe which conveys effluent to the drain field or leach area for onward treatment.
How do I know if my drain field is failing?
The following are a few common signs of leach field failure:
- Grass over leach field is greener than the rest of the yard.
- The surrounding area is wet, mushy, or even has standing water.
- Sewage odors around drains, tank, or leach field.
- Slow running drains or backed up plumbing.
What do septic field lines do?
Septic Fields Distribute Liquid Effluent The pipe or the galleries are placed in a bed of gravel that helps disperse the liquid. As the effluent percolates through it, the soil absorbs residual bacteria and particles so that by the time the water reaches the aquifer deeper underground, it’s pure enough to drink.
How do I check my septic tank field lines?
Scan the area for markers: The location of your septic tank should be marked by a cement marker the size of a manhole cover. Look for it 10 to 20 feet away from your home. Once you locate the tank, follow the downward-most path and check for an empty downward-sloping field. You may have just found your drain field.
What causes a septic drain field to fail?
Many things can cause a septic field to fail, but the primary culprit in septic field failure is overloading, either from too much water or biological overgrowth. Flooding the septic system – and eventually the septic field – with too much water can cause field failure.
How deep are leach field lines?
A standard leach line is considered to be three (3) feet wide and three (3) feet deep with a length as required.
How long does a drain field last?
It’s important to consider the life expectancy of a drain-field, too. Under normal conditions and good care, a leach-field will last for 50 years or more. Concrete septic tanks are sturdy and reliable but not indestructible.
How long are leach field lines?
The leach field is a series of trenches that may be up to 100-feet long and 1 foot to 3 feet in width, separated by six feet or more, depending on local requirements, and sometimes constructed leaving space between the original lines to install replacement leach lines when needed.
What are the signs that 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 you walk on a leach field?
Your family can walk on a well-maintained drain field without fear of encountering puddles of affluent and dangerous bacteria. Bicycles and tricycles are also acceptable because they are not heavy enough to compress or disturb the soil.
What do lateral lines look like?
Lateral lines are usually visible as faint lines of pores running lengthwise down each side, from the vicinity of the gill covers to the base of the tail. Most amphibian larvae and some fully aquatic adult amphibians possess mechanosensitive systems comparable to the lateral line.
What ruins a drain field?
Dripping faucets, running commodes, and malfunctioning water softeners put extra water into the septic system, which can flood out your drainfield. Higher-than-normal usage on the system from occupants or visitors can overload the system as well.
Is Ridex good for your septic system?
How additives, like Rid-x, interfere with your septic system’s eco-system. According to the EPA and the Ohio Department of Health, not only are additives like Rid-X not recommended, but they actually have a detrimental and potentially hazardous effect on your septic system’s waste treatment process.

What Drain Field Lines Do
Even with the best septic system, effluent, or waste water from the tank, must eventually empty into the environment. There are a plethora of alternatives available in this situation. Some people prefer to let the sewage drain into a pit. Another option is to use a graywater recycling system to recycle the effluent. The leach field, on the other hand, is the most popular. The effluent travels through a network of subterranean pipes (drain field lines) that are punctured with numerous small holes in order to achieve this configuration.
The drainfield itself plays a significant role in cleansing the effluent and ensuring that it is safe to discharge into the environment.
Bacteria may also be found in the soil, which means that as long as the flow of effluent stays sluggish, your on-site waste treatment plant will remain healthy and safe for both the environment and the people who live in the surrounding area.
Don’ts of Drain Field Lines
Place anything heavy on top of them to make them more stable. If the soil compacts, it will be unable to absorb the effluent; thus, do not construct anything on top of it (patios, gazebos, swimming pools, play equipment, etc.), and do not allow anybody to drive over it. Anything other than grass should be planted on or around them. The roots have the potential to clog or harm the pipes. Increase the load on the system. If an excessive amount of effluent is introduced into the system at one time, it will not be properly treated, and solids will reach the drainfield.
Spend money on system treatments that aren’t necessary.
Dos of Drain Field Lines
Pump your system on a regular basis. For a typical home, this implies every 3-5 years, or even more frequently if you have a waste disposal in your kitchen. If your septic system is located on commercial or industrial land, it will need to be serviced on a regular basis. This guarantees that sediments do not make their way into the drainfield and cause it to get clogged. Keep a close watch on everything. Keep an eye out for indicators of failure, such as stagnant water or an excessive amount of plants growing on top of it.

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.
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
What Is a Leach Field and How Does It Work?
Have you ever phoned a septic firm to assist you in resolving an issue with your system, only to hear them speak about leach field replacement or repairs and not understand what they were talking about? The leach field, also known as the drainfield, is a component of the sewage treatment system that is often overlooked. It is a network of subterranean wires or pipes that is surrounded by gravel, sand, or porous soil to keep out water.
The septic tank and the distribution box or chamber are two other septic system components to consider. Although there are septic systems that do not require a leach field, they are often more expensive and are not a practical option for many homeowners.
How Does a Leach Field Work?
A series of tiny holes can be found along the sides and bottom of the lines or pipes in the septic leach field. As wastewater travels through the pipes, it seeps into the gravel, sand, or soil that surrounds them, causing contamination. Solid waste is retained in the septic tank and is prevented from flowing out by a filter. The bacteria in the leach field septic layer subsequently decompose the organic elements in the wastewater, resulting in its purification.
What Is the Best Leach Field Distance From Your House?
The drainfield is typically installed on an open, flat area adjacent to the home, where it can be easily seen. The actual distance between the two points may differ depending on the layout of the land and the specifications of the systems. It is preferable to make the selection with the assistance of a professional. To achieve this, the leach field should be located close enough to the house to save needless piping expenditures, yet far enough away from the house to prevent water infiltration into the home’s walls.
Consulting an expert is the most effective approach to ensure that all of these factors are taken into consideration, as well as to acquire answers to additional issues that you would have a difficult time answering on your own, such as:
- Is it possible to have a septic tank without having a leach field? What is the function of a septic tank and leach field
- What is the normal depth of a leach field installation
- What are the bare minimum standards for leach field maintenance? How long should a leach field be in operation
. and much more. The bottom line is that it takes more than just knowing the concept of a leach field and reviewing a leach field size chart to design a system that works well for you. It needs much more knowledge to understand how to resolve leach field issues.
Typical Septic System Leach Field Problems
Most septic system problems may be traced back to a problem with the drainfield, in most cases. Solid waste or wastewater can accumulate on the soil at the leach field bottom, clogging the drainage system and preventing it from functioning properly. This generally occurs when one of the following conditions exists:
- Besides chemicals, you’re also draining paint, grease, and other complicated compounds that are tough to filter out. The amount of wastewater that has to be treated exceeds the capacity of the system. The top layer of the drainfield was damaged as a result of building activities or cars. The volume of water that needed to be filtered increased as a result of excessive rainfall or snow. Plant and tree roots cause obstructions in the pipes. Several of the pipes are fractured or fissured, and they are ancient and rusted
Another factor contributing to drainfield issues is a failure to do regular septic tank pumping to eliminate sludge. Interventions are advised to be performed every two years, however depending on the size of the family and the demands of the home, even more regular septic pumping interventions may be required. However, if your drainfield is showing indications of problems, it is never a smart idea to attempt to resolve the situation on your own. Instead, you should think about how to locate leach field expertise and delegate responsibility for the problem to them.

SEPTIC SYSTEM articles are available for viewing here. Unless a municipality has installed a “on-site sewage disposal system,” often known as a septic system, each residence in such an area must treat its sewage on its own property.
One of the most commonly seen types of leach field is composed of a succession of perforated distribution pipes, each of which is situated within a gravel-filled absorption trench.
Leach Field
When used properly, a leach field (also known as a “drain field”) is a series of perforated pipes that are typically buried in gravel trenches 18 to 36 inches below grade — deep enough to avoid freezing, but close enough to the surface that air can reach the bacteria that further purify the effluent (see illustration below). As little as 6 inches might separate you from the ground surface, depending on your soil type and municipal regulations. It is customary to cover the perforated pipes with approximately two inches of gravel and a layer of topsoil that is 18 to 24 inches in depth.
- Grass is often sown above the ground.
- The leach field is comprised of rows of perforated pipes in gravel trenches that are used to spread wastewater over a vast area in order to further purify it.
- A bacteria-rich slime mat forms where the gravel meets the soil, and it is responsible for the majority of the water purification work.
- Despite the fact that wastewater freezes at a far lower temperature than pure water, freezing is still a hazard in cold areas.
- The leftover pathogens are converted into essential plant nutrients by these organisms, while sand, gravel, and soil filter out any solids that remain.
- If the system is operating effectively, the filtered wastewater will return to the aquifer as naturally clean water that is suitable for human consumption at this stage.
- Alternative systems may be permitted in situations when traditional leach fields are unable to function properly owing to poor soil conditions or a high water table.
These systems sometimes cost twice or three times as much as a regular system and require significantly more upkeep. Special systems may also be necessary in regions where there are flood plains, bodies of water, or other ecologically sensitive areas to protect against flooding.
SIZING THE LEACH FIELD
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 prevent freezing, but close enough to the surface to allow air to 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 laws. Approximately two inches of gravel and a topsoil layer, generally 18 to 24 inches deep, are placed over the perforated pipes to protect them.
- Most of the time, grass is planted above the surface.
- As part of the purification process, the effluent is distributed across a vast area using rows of perforated pipes set in gravel trenches.
- In the perforated pipes, the effluent is channeled into the surrounding gravel and then into the native soil.
- Because freezing will impede the bacterial action that is necessary for the system to function, all elements conveying liquid must be buried deeply enough to prevent freezing.
- A little amount of the leftover liquid, which contains minute suspended particulates, percolates into the native soil, where it is treated by bacteria and other microscopic animals that live in the soil to complete the process.
- While a portion of the liquid evaporates into the atmosphere, the remaining portion is absorbed by plant roots (Figure 1).
- In fact, it’s a fairly clever approach that takes full use of nature’s extremely successful method for recycling organic waste.
- A standard system might cost two or three times as much as a high-end system, and they require more frequent servicing.
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. This will assist you in keeping the load controlled and will also help to extend the life of your system. To minimize overburdening the system, the following measures should be taken:
- Distribute your washing loads and other high-water-use activities across the week
- And In the kitchen and bathroom, use low-flow appliances, faucets, and fixtures. Toilets, in general, are the source of the greatest amount of water use. Water should be diverted away from the leach field from the yard, gutters, and basement sump pumps.
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.
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.

What You Need to Know About Your Septic System’s Drainfield
In the absence of a municipal sewer system, the likelihood is that you are utilizing an aseptic system for all of your wastewater disposal. It is your septic tank that is emptied every time you flush the toilet or when water drains down the drain from sinks or the laundry. Residential septic systems are available in a variety of configurations, but they invariably include an aseptic tank, into which wastewater is channeled for treatment, and a drainfield, into which effluent evaporates or drains into the ground.
What Is a Septic System Drainfield?
In order for a septic system to work correctly, drainfields, also known as leach fields or absorption fields, must be installed. Drainfields collect and manage wastewater that has been pumped from the septic tank and are thus essential. They are comprised of perforated pipes that are buried two to four feet underground and lead away from the tank. Septic tanks would overflow if a drainfield was not there, resulting in runoff and a foul stench in your yard. Whenever everything is operating properly, the soil in the drainfield filters the wastewater, and naturally occurring bacteria and microorganisms decompose the solid waste.
What Are the Signs There Is a Problem With Your Drainfield?
- Waste smells, particularly outside in the vicinity of the septic tank and drainfield
- Predominant presence of dark green, luxuriant flora covering the drainfield It may be visually appealing, but it indicates a severely overburdened septic system. It’s possible to have wet, soggy, or spongy regions over your septic tank or drainfield even in dry weather. It’s possible that you’ll discover puddles of standing water. Kitchen and bathroom drains that are too slow
- Toilets that are overflowing or sewage backups
What Are the Causes of These Problems?
A drainfield can live for 50 years or longer if it is properly cared for and maintained. However, several of the indications listed above might indicate that a drainfield is beginning to fail. The system just does not have the capability to take any additional garbage. Sewage backups, a foul stench outdoors, and sluggish drainage within your house are all possible consequences of this.
Crushing damage
A drainfield can survive for 50 years or more with proper care and upkeep. A number of the indicators listed above, on the other hand, may indicate that a drainfield is beginning to fail. Simply put, the system’s capacity to receive garbage has reached its maximum level of capacity. Sewage backups, bad odors outdoors, and sluggish drainage within your house are all possible consequences of this.
Pipes are blocked
A possible source of obstruction is the infiltration of tree and plant roots into sewer lines, which prevents wastewater from draining correctly. The accumulation of sludge and the flushing of objects that should not be flushed down the toilet can also cause clogging of pipes.
The septic system is overloaded
Doing multiple loads of laundry on the same day as running the dishwasher might cause the septic system to become overburdened. A leaky faucet or a gurgling toilet might also be problematic. Time is required by all septic systems in order for the effluent to pass through the treatment procedures. It is otherwise necessary to compel wastewater to flow into the drainage field at a quicker pace than the drainage field is capable of handling. This can result in standing water or the mushy, spongy conditions described above.
Gutter downspouts draining over the drainfield
Having gutters that drain across the septic system drainfield makes it more difficult for the drainfield to absorb wastewater and perform its function.
This might result in a squishy region that is constantly wet or standing water.
What to Do to Maintain a Healthy Drainfield
- Heavy machinery, automobiles, recreational vehicles, boats, grazing animals, and structures should be kept away from the area above your drainfield. Planting trees or other plants over your drainfield might cause harm to the pipes since the roots will grow into them. Make certain that all gutter downspouts are directed away from the drainfield. Every two to three years, have your septic tank pumped. Solids are conveyed into the drainfield by the absence of frequent pumping, resulting in blockage of the pipes. Apart from the waste that comes out of your body, the only item that should be flushed down the toilet is toilet paper. Other solids should not be flushed. Additionally, refrain from dumping any fats, oils, or grease down your drains. You should space out your laundry and dishwashing days so that you don’t overburden your septic system.
SEPTIC-TANK DRAIN FIELDS: WHAT YOU SHOULD KNOW ABOUT PROTECTING THEM FROM HARM
While a septic system may appear to be impenetrable, the fact is that neglect may cause severe damage, which may even result in a complete shutdown of the system. Septic systems may give many years of reliable service if properly maintained, but they can also be completely damaged by reckless actions. The drain field is an element of your septic system that is particularly prone to failure. More information on this crucial component, as well as numerous important measures that will help to keep your drain field in good condition, may be found in the sections below.
- Generally speaking, a septic drain field is the region where effluents, which are liquid waste products produced by the system, are discharged into the soil, after which the liquid waste products seep through the soils around the area.
- From a structural standpoint, drain fields are composed of many parallel pipelines that empties into a particular substrate that is buried several feet beneath the surface.
- It is for this reason that being vigilant in protecting the septic drain field is so critical to success.
- Because drain fields are so critical to the overall health of a septic system, you must take a proactive approach to prevent them from being damaged or destroyed.
- Keep impurities out of the system that might clog it.
- Never put grease, oil, or other scum-forming compounds into the septic system in order to avoid this situation from developing.
- Instead, direct gray water to a sump pump that will be used solely for disposal.
Drain-field components are often only a few feet below ground level, making them accessible to things that might create a clog or other problems.
Among the other potentially harmful aspects are storage sheds and pavement that is too close to the drain field; anything that creates long-term weight stresses on drain fields should be avoided.
Keep biological activity at a high level.
It is possible to disrupt this activity by killing beneficial microorganisms and cause an imbalance in the environment, which may result in the cessation or reduction in the effectiveness of filtering and cleansing of effluent.
Detergents, pesticides, insecticides, fertilizers, and other potentially toxic compounds are examples of such agents.
On a regular basis, carry out the necessary “upstream” maintenance tasks.
However, even in the absence of dangerous chemicals being introduced into the effluent, the regular processes occurring inside a septic system might eventually result in the closure of drain fields.
Effluent filters, for example, should be cleaned and replaced on a regular basis.
Another important maintenance operation is the pumping out of accumulated sludge that has developed at the tank’s bottom.
Regular pumping of tanks, which may be as often as once a year, is necessary to prevent sludge from departing the tank and contaminating the drain-field lines and causing a backup.
Septic drain field – Wikipedia
Septic drain fields, also known as leach fields or leach drains, are subsurface wastewater disposal facilities that are used to remove contaminants and impurities from the liquid that emerges after anaerobic digestion in an aseptic tank. Septic drain fields are also known as leach fields or leach drains. Microbial ecosystems decompose organic molecules in liquids by using them as energy sources. Aseptic systems are made up of a septic drain field, an aseptic tank, and any related plumbing. An arrangement of trenches with perforated pipes and porous material (oftengravel) topped with a layer of soil to prevent animals (and surface runoff) from getting the wastewater spread inside those trenches is characteristic of a drainage field.
A septic reserve area is a piece of land that has been set aside for the purpose of constructing a septic drain field (SRA).
These are more common in dry regions because the waterflow on the surface allows for irrigation (and fertilization) of agricultural land, which is beneficial in droughts.
Design
A drainage field is being constructed. Many health agencies demand an apercolation test (also known as a “perc” test) to determine if drain field soil is suitable for receiving septic tank effluent. To build a system that meets these requirements, an engineer, a soil scientist, or a licensed designer may be necessary to collaborate with the local governing agency. Direct monitoring of the soil profile provides a more progressive method of determining the size of leach fields. During this observation, the engineer examines a variety of soil characteristics, including texture, structure, consistency, pores/roots, and so on.
When wastewater is transported away from the drain field before pathogens are killed, coarse soils such as sand and gravel can be used.
Tests for percolation are conducted to determine the pace at which clean water disperses down a disposal trench and onto the surrounding soil.
These include:
- Septic tank effluent will be adhered to soil particles by microbial colonies that are catabolizing soluble organic compounds from the effluent. This will diminish the interstitial space available for water movement between soil particles. When these colonies colonize the soil interface of the disposal trench, they tend to produce a biofilm of gelatinous slime with a limited permeability. A buildup of insoluble particles that are too small to be carried through the septic tank will occur at the soil interface of the disposal trench, while non-biodegradable particles such as synthetic fibers from laundry, mineral soil from washing, or bone and eggshell fragments from refuse will remain to fill the interstitial spaces that were previously available for water flow out of the trench. Flowing cooking fats or petroleum products emulsified by detergents or dissolved by solvents can pass through prior to anaerobic liquefaction when the septic tank volume is insufficient to provide adequate residence time, and they may congeal as a hydrophobic layer on the soil interface of the disposal trench. The availability of hydraulic head (or vertical distance) may be reduced as a result of rising groundwater levels, forcing gravity water flow away from the disposal trench. It is possible that effluent running downward from the disposal trench will eventually reach groundwater or impermeable rock or clay, prompting a change in direction to horizontal movement away from the drain field. In order for gravity force to overcome viscous frictional forces preventing flow through porous soil, a specified vertical distance between the effluent level in the disposal trench and the water level applicable when the effluent leaves the drain field must be maintained. If groundwater levels surrounding the drain field approach the level of effluent in the disposal trench, effluent levels in the region of the drain field will increase toward the ground surface in order to maintain the vertical distance difference
- Frozen ground may diminish the cross-sectional area available for flow or evaporation on a season-to-season basis.
Catabolic design
Septic tank effluent will be adhered to soil particles by microbial colonies that are catabolizing soluble organic molecules, reducing the interstitial space available for water movement between soil particles. When these colonies colonize the soil interface of the disposal trench, they tend to produce a low-permeabilitybiofilmof gelatinous slime. A buildup of insoluble particles that are too small to be carried through the septic tank will occur at the soil interface of the disposal trench, while non-biodegradable particles such as synthetic fibers from laundry, mineral soil from washing, or bone and eggshell fragments from refuse will remain to fill the interstitial spaces that were previously available for water flow out of the trench; Cooking fats or petroleum products that have been emulsified by detergents or dissolved by solvents can flow through prior to anaerobic liquefaction when the septic tank volume is too small to provide adequate residence time, and they may congeal as a hydrophobic layer on the soil interface of the disposal trench Gravitational water flow away from the disposal trench may be caused by rising groundwater levels reducing the available hydraulic head (or vertical distance).
It is possible that effluent running downward from the disposal trench will eventually reach groundwater or impermeable rock or clay, forcing a change in direction to horizontal flow away from the drain field.
If groundwater levels surrounding the drain field approach the level of effluent in the disposal trench, effluent levels in the region of the drain field will increase toward the ground surface in order to maintain the vertical distance difference.
Biofilter
In some cases, when an aseptic tank is utilized in conjunction with a biofilter, the drain field’s height and catabolic area can be lowered. High-density residential building, less site disturbance, and more useable space for trees, swimming pools, and gardens are all possible using biofilter technology. It is possible that proper periodic maintenance will lessen the likelihood of the drain field becoming clogged. It is unlikely that the biofilter will lower the amount of liquid that must percolate into the soil, but it may reduce the oxygen demand of organic molecules in the liquid that is being treated.

Dosing schedules or resting periods
Several distinct disposal places for effluent from a single septic tank can be provided by a drain field, which can be constructed to accommodate several septic tanks. It is possible for one region to be “rested” while effluent is channeled to another location. When the anaerobic septic tank effluent is no longer accessible, the nematode colony in the resting drain field continues to feed on the biofilm and lipids that have formed in the field. As the organic material that has collected in the soil is oxidized, this natural cleaning process may help to prevent bioclogging and increase the hydraulic capacity of the field by expanding the accessible interstitial area of the soil.
Inappropriate wastes
Microorganisms in septic tanks and drain fields have very limited ability to catabolize petroleum products and chlorinated solvents, and they are incapable of removing dissolved metals, despite the fact that some metals may be absorbed into septic tank sludge or drain field soils, and their concentrations may be diluted by other groundwater in the vicinity of the drain field (see Figure 1). It is possible that cleaning formulas will affect the efficiency of the drain field. The use of laundry bleach, as well as sanitizing and deodorizing chemicals, may have a comparable effect on microbial activity in the drain field.

Field Lines and Tanks
That’s a great question! Briefly stated, onsite waste water treatment systems are those that handle and purify domestic waste water on-site (effluent) A mixture of black water (toilet waste) and grey water makes up the effluent (kitchen, bath, laundry). A septic system is made up of two parts: a septic tank and field lines (or drains) (also referred to as a leach field). The first stage of treatment takes place in the septic tank, where microorganisms break down organic compounds in the effluent.
Secondary treatment takes place in the field lines after the wastewater has been discharged. In this location, bacteria complete the digestion and purification process while wastewater slowly seeps into the soil or infiltrates into the ground.
THE SEPTIC TANK
The septic tank is an underground box that is “watertight.” It is typically made of concrete and is around eight feet length, four feet wide, and five feet deep. It has a minimum storage capacity of 1,000 gallons. During the flow of wastewater into the tank, heavy materials fall to the bottom and accumulate as a sludge layer, whilst grease and fats rise to the surface and accumulate as a layer of scum. There is a transparent zone of liquid in between these two levels. Billions of bacteria that exist naturally in the tank may be found in all three of these levels, and they are responsible for the first step of therapy, which is the breakdown of solid debris.
THE FIELD LINES
The partially treated effluent from the tank is discharged onto the field line system, which is normally comprised of two or more trenches. This is the location where wastewater is naturally cleansed as it percolates through the soil and into the groundwater. Distance between trenches and depth of trenches to the bottom are dictated by the local health agency and/or the engineer who designed the trench system. The types of soil present, as well as the depth of the water table, define the distance and depth of the water table.

How your Septic System Works
Although what occurs with wastewater is sometimes overlooked when seeking to purchase a new home, it is a critical component of any residence. There are two major methods in which the drain system for your home disposes of wastewater; you will either be connected to a sewer system or have a septic tank installed. The majority of people are inexperienced with the operation of septic tanks, which can create worry among first-time homeowners. In order to handle all wastewater from the house and disseminate it in a manner that is safe for both you and the environment, septic systems are specifically constructed.
Septic Tank
The septic tank is the first phase in the wastewater treatment process. Every plumbing fixture in your home will discharge into the septic tank, where it will begin to decompose. Solid matter will settle to the bottom of the container, creating an environment that is favourable to microbial growth. These bacteria will begin to decompose the solid waste, releasing water known as effluent as well as an oil that rises to the surface of the water. Baffling connects the two halves of the septic tank, which are joined by L-shaped pipes called baffles.
Only the effluent water is allowed to pass via these valves and into the septic system. It is necessary to repeat this procedure twice more before the wastewater is ready to be discharged back into the environment.
Drain Field
In a drain field, also known as a leach field, effluent water is allowed to dissipate into the soil through a network of perforated pipes. These pipes are typically buried one to two feet below ground level and are surrounded by gravel to aid in the distribution of the water uniformly throughout the system. In addition, when the effluent water sinks to the water table, the earth absorbs any extra bacteria or particles that were not removed by the septic tank. By the time it reaches the water table, the water has been proven to be absolutely harmless.
How to Care for your Septic System
Being aware of the operation and maintenance of your septic system will help it survive longer and continue to perform properly for a long period of time. When it comes to septic system maintenance, there are numerous factors to keep in mind. In order to function properly, septic systems require a delicate balance of bacteria and waste products. If you flush a large amount of sediments or items that cannot be broken down by these bacteria, the system may become clogged and ineffective. Waste goods such as disposable wipes, coffee grounds, feminine products, and many more can cause difficulties in your septic system.
To avoid this potential problem, make sure that you are aware of the location of your drain field.
To avoid this potential problem, make sure that you are aware of the location of your drainage field.
Every two to three years, it is advised that you pump the tank out.
Signs of Failure
Knowing some of the warning signs of a probable breakdown in your septic system might help you avoid more serious problems in the future. When the system is not functioning effectively, it can manifest itself in a variety of ways, including an unpleasant odor around the septic field, sluggish emptying toilets and sinks, and excessive plant growth over the field. You should contact a specialist if you detect any of the indicators of failure listed above, as soon as possible. Withholding attention to any problems with your septic system will result in more extensive and expensive repairs down the road.
Many homeowners are concerned about how their septic system works, but this is not something that they need be concerned about.

- 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 located, make a rough sketch of its location 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.
