is overloaded with too much liquid, it can flood, causing sewage to flow to the ground surface or create backups in toilets and sinks. Finally, the wastewater percolates into the soil, naturally removing harmful coliform bacteria, viruses and nutrients.
- Your septic drain field is designed to help all the wastewater flowing from your septic tank dissipate into the surrounding environment. Much of the water drains down through the topsoil and is eventually filtered into the groundwater. However, a good portion of the water also travels to the surface to evaporate in the air.
How do you tell if your drain field is clogged?
Stay vigilant for five signs your drainfield does not drain correctly anymore.
- Slowing Drainage. Homeowners first notice slower than usual drainage from all the sinks, tubs, and toilets in a home when they have a compromised drainfield.
- Rising Water.
- Increasing Plant Growth.
- Returning Flow.
- Developing Odors.
Can you fix a clogged septic drain field?
It is often possible to clean and renew a clogged septic leach field instead of replacing the drain field lines. Septic field lines can fail to drain when heavy solids accumulate and block perforations in the lines. You can use a sewer jetter to clean perforated PVC septic leach field lines from 2″ to 6″ ID.
What causes septic drain field failure?
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 do you unclog a septic drain field?
Can Anything Unclog an Old Septic Drain Field?
- Shock the System With Bacteria. A septic system bacteria packet can help clean out a clogged drain field by allowing waste material to break down and drain through.
- Reduce Water Usage.
- Avoid Harsh Chemicals.
- Change to Gentler Toilet Paper and Soap.
- Contact a Septic Professional.
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.
What happens when drain field fails?
A clogged leach field will compromise the entire system. It can result in sewage backups in the house, septic odors, sewage leakage on the lawn, and contamination of groundwater. To avoid these and more problems related to leachfield failure, you should unclog your leachfield through shock treatment.
What is the average life expectancy of a septic system?
Age of the System It’s pretty common for a septic system to last 40 years or longer, which means if you buy a new home, you might never need to replace it. However, you might have an older home whose septic system has been in place for nearly half a century.
What can I do about a saturated septic field?
Additional ways to help keep the soil in your drain field from becoming over-saturated include:
- Avoid using too many water fixtures in the home at once.
- Ensure all home gutter downspouts are directed away from the drain field.
- Don’t point lawn sprinklers toward drain field.
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.
How often do drain fields fail?
You can expect your septic drain field to last anywhere from 10 to 30 years, depending on the level of care the septic system receives over its lifetime.
Can a leach field be restored?
A drainfield that isn’t working properly could result in clogged drains and the release of raw sewage on the ground’s surface. A failing drainfield can, and should, be restored quickly to avoid permanent damage. Biological, organic, and inorganic additives can be used to restore functionality to a failing drainfield.
How far down is a leach field?
A typical drainfield trench is 18 to 30 inches in depth, with a maximum soil cover over the disposal field of 36 inches.
How much does it cost to clean a leach field?
Leach field 1 rejuvenation costs between $1,500 and $5,000. This method is used to clean leach fields that have become clogged or soaked with wastewater and solid waste.
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. In order to enable solids to settle to the bottom and form sludge, while oil and grease float to the top and produce scum, the tank must be large enough to contain both. Compartments and a T-shaped outlet prevent sludge and scum from leaving the tank and moving into the drainfield region. 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. Drainfields can flood if they become overloaded with liquid, causing sewage to overflow to the ground surface or causing backups in toilets and sinks. If a drainfield becomes overloaded with liquid, it can flood, causing sewage to overflow to the ground surface or causing backups in toilets and sinks
- And if a drainfield becomes overloaded with liquid, it can flood. Finally, the wastewater percolates into the soil, where it is naturally removed from the environment by coliform bacteria, viruses, and nutrients that are hazardous to humans. 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
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.
- It is also recommended that you refrain from dumping gray water into your septic system if at all feasible since detergents and dissolved lipids present in dish and laundry wastewater might eventually contribute to the problem.
- Protect the physical components of the drain field Because drain-field components are often just a few feet below ground level, they are exposed to anything that might create a disturbance.
- 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.
As with any aspect of your septic system, maintaining a healthy amount of biological activity in the drain field is essential to keeping the process running smoothly.
As a result, it is critical to prevent allowing bactericidal agents to have direct access to the effluent or to flow down into the groundwater.
Sometimes, even medications used by members of the family can make their way into the septic system and have a powerful antibacterial effect on the “good” germs that live there.
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.
3 Signs of a Septic Tank Drain Field Problem
Your septic tank drain field (also known as a leach field) is a critical component of your septic system’s operation. Basically, it’s there to filter impurities from the liquid wastewater that comes out of your septic system. Depending on how your system is configured, this liquid, referred to as “effluent” in plumbing jargon, may reach the drain field by the force of gravity or with the use of pumping equipment. Having a problem with your drain field is very prevalent when it comes to septic system problems.
Here are three techniques to determine whether or not you may have a septic tank or drain field issue at your residence.
1. A Bad Smell
If you discover a foul stench in your yard or on your property and are unable to identify an alternative reason, the likelihood is that you have a septic tank drain field problem. It is easily visible by anyone with a nose when wastewater is not draining correctly and gathers in the soil near the surface, resulting in an unpleasant odor that can be detected by anyone with a nose. Don’t put off dealing with any potential problems with your septic system any longer. Keep in mind that having your tank pumped is simply a short-term remedy to a drain field malfunction.
2. Standing Water
If you notice puddles of water in your yard and it hasn’t rained in a while, you should have your septic tank inspected as soon as possible. After a sufficiently enough time of effluent accumulation as a result of inadequate drainage, the liquid runs out of space and spills into the soil. Your children or dogs should not be allowed to play in these puddles under any circumstances.
3. Drainage Issues in Your Home
Clogging and backups within your home can be caused by a clogged or malfunctioning septic tank drain field, among other things. If the drains in your sinks, bathtubs, and showers are running extremely slowly, you may be experiencing drain field troubles. It is possible that a slow-flushing toilet is indicative of the necessity for a professional septic system inspection. Your septic system has reached the stage where backups are occurring in your home, and you are at danger of experiencing a costly and unsanitary overflow situation if you do not address the problem immediately.
A drain field failure is most likely to blame.
If you believe that your house is suffering from septic troubles, contact a professional plumbing firm to examine and identify the situation before it becomes worse.
Contact The Pink Plumbertoday if you have any questions regarding your septic system or any other plumbing difficulties you are experiencing. OUR EXPERT PLUMBERS ARE AVAILABLE TO HELP YOU.
How a Septic System Works – and Common Problems
Clogging and backups within your home might be caused by a clogged or malfunctioning septic tank drain field. A clogged drain field might be the source of sluggish drains in your sinks, baths, and showers. It is possible that a slow-flushing toilet is indicative of the need for a professional septic system examination. The sooner you address any septic issues that are generating backups in your home, the less likely it is that you will experience a costly and unsanitary overflow situation. Whether or not you’ve recently had your septic tank emptied, if you’re having these issues, it’s probable that a drain field failure is to blame.
– Call a professional plumbing firm to evaluate and diagnose any septic difficulties you may be experiencing at your house before the situation worsens.
FOR YOUR CONVENIENCE, OUR EXPERTS IN PLUMBING ARE ON HAND.
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). In other cases, the distance from the surface might be as little as 6 inches depending on the soil type and municipal requirements. The perforated pipes are covered with around two inches of gravel and a layer of topsoil that is generally 18 to 24 inches deep.
- Grass is often sown above the ground.
- The leach field is comprised of rows of perforated pipes in gravel trenches that distribute the effluent over a large area for further purification.CLICK TO ENLARGEThe effluent passes from the perforated pipes into the surrounding gravel and then onto the native soil.
- During this process, the leftover pathogens are converted into essential plant nutrients while sand, gravel, and soil filter out any remaining solids.
- 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.
- It’s a very smart technique that takes full use of nature’s highly successful mechanism for recycling organic waste.
- 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.

5 Signs Your Septic Drainfield Has Stopped Working
Unlike municipal septic systems, which consist just of a subterranean tank that collects waste and water, residential septic systems are more complex. Water finally departs the tank through an outlet pipe and into a network of long perforated pipes known as the leech or drainfield after reaching the tank’s interior. The drainfield is equally as vital as, if not more so than, the septic tank in terms of wastewater treatment. In the event that this component of the system begins to fail, prompt action might mean the difference between relatively small repairs and a total drainfield replacement.
- Drainage is being slowed.
- As long as there is still any water in the pipes of the field, the drains in your home will continue to function, albeit at a slower rate.
- The presence of obstructions in the inlet or outlet pipe, as well as several other septic problems that are less difficult to resolve than drainfield problems, might result in delayed drainage.
- You may detect puddles or spongy and mushy ground all over the place if you look closely.
- A backup occurs when the water level rises to a level that forces sewage up the input pipe and into the lowest drains in your house, which is known as a back up in the system.
Drainfield leaks can provide visible consequences on the surface if the drainfield leaks at a higher rate than typical or contains decaying material that is meant to remain in the tank.
Returning Flow is the fourth step.
If you presume that the tank just need pumping, the service technician may discover water and sewage entering the tank from the outlet in a reverse flow, which would indicate that the tank requires more than pumping.
The presence of reverse flow from the drainfield is an obvious indication that you want jetting or pipe replacement services.
The Development of Odors In the end, you can utilize your sense of smell to detect indicators of drainfield issue.
Any sewage or toilet scents, even if they are weak and difficult to detect, signal that you should have a professional evaluate your home immediately.
This is the most effective way.

5 Things Homeowners Should Know About Their Septic Drain Field
There are certain distinctions in care, usage, and budgeting that you should be aware of, whether you’re a new homeowner with an existing septic system or considering about purchasing or building a home without sewer hookups. This document outlines three ways in which your budget will be affected if your wastewater is treated using a septic system. 1. You will not be required to budget for municipal sewer service. Because the municipal wastewater system normally processes all of the water, the cost of city sewage service is sometimes determined by how much water you purchase from the city.
- A large number of homes with septic systems also rely on wells for fresh water rather than municipal water, which means you’ll likely save money in that department as well.
- It is necessary to include septic maintenance in your budget.
- Although you are not required to pay the city for the usage of your septic system, you will be responsible for the costs of maintenance if you want the system to continue to function properly.
- It is possible that these maintenance and repair expenditures will build up over time, so you may want to consider setting up an emergency fund to cover any unforeseen repair bills.
- You’ll also need to budget for the cost of a single inspection and begin saving for the cost of a tank pump.
- Spreading the expenditures out over several months is the most effective budgeting strategy, even for an expense such as tank pumping that does not occur every year, because it allows you to better estimate the costs ahead of time.
- You may need to set aside money for septic tank replacement.
The tank and leach field may not need to be replaced if you have a reasonably recent septic system and plan to sell your home within a few years.
If, on the other hand, your home’s septic system is more than a decade old, you’ll want to start looking into how much a new system would cost you as soon as possible.
For example, if the previous owners did not do routine maintenance or if the system was installed on clay soil, the system may need to be replaced.
It is a prudent decision to begin putting money aside in anticipation of this eventuality.
When you have a septic system, you may use these three strategies to budget differently.

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.
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.
- 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.
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.

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.
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.
Operation and maintenance
A septic drain field that has been exposed due to erosion
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.
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.

Septic Tank Drain Field Problems
WebAdminon has written this article. Postings under Uncategorised For those of you who are responsible for maintaining the integrity of your septic system drain field, you should make certain that you are doing all possible to keep it in good working order. Drain fields in a conventional septic system can endure for up to 20 years or more before they need to be replaced. While it is true that more than half of all septic systems fail before they reach this age, the Environmental Protection Agency (EPA) says that this is typically due to difficulties with the drain field.
- Effluent is discharged into your drain field after your septic system has separated wastewater from solid waste (sludge), which is termed effluent separation.
- What is the process through which earth purifies water?
- These bacteria naturally eliminate toxins from the wastewater that is pushed into the drain field by digesting, breaking down, or absorbing the substances that are present.
- Compaction of drain field soil eliminates the extremely small pockets of air that exist between soil particles, resulting in the death of the aerobic bacteria that thrive in the soil.
- Because of this, you must maintain the looseness of the soil in your drain field.
- Avoid parking vehicles on the drain field, driving over it, constructing sheds or other small storage structures on the drain field, as well as placing pet kennels or other large objects on the drain field.
- When the earth becomes overly saturated with water, it is unable to effectively filter effluent, which can result in wastewater backing up into your septic tank and ultimately into your home’s plumbing fixtures.
- First and foremost, you should never lay anything over your drain field, such as a tarp, that will prevent water from evaporating off the surface of the drain field.
These plants require water in order to survive, and they will absorb water from the drain field in order to prevent soil over-saturation and over-watering. Additional measures that may be taken to prevent the soil in your drain field from being over-saturated are as follows:
- It is best not to use too many water fixtures in the house at the same time. When an excessive amount of water comes down your house drains and into your septic system at the same time, it all pours into the drain field at the same time and can create drain field flooding. Ensure that all downspouts from residential gutters are directed away from the drain field. Rain falling directly on your drain field can occasionally oversaturate it, but your drain field is more likely to become oversaturated after a downpour if your home gutter downspouts are pointing in the direction of your drain field. Lawn sprinklers should not be directed toward the drain field. Any plants or grass growing on top of your drain field should be able to absorb water and nutrients straight from the soil and so require no further watering.
To further prevent septic tank backups, which can result in flooding of your drain field, be cautious about what you flush down the toilets. Make certain you use toilet paper that has been designated as septic-tank safe. 3. Infiltration of tree roots Your septic system drain field is also filled with a network of pipelines that transfer wastewater uniformly across the drain field soil, in addition to plenty of dirt. It is critical to safeguard the integrity of these pipelines, just as it is to protect the integrity of the soil.
- It is possible for tree roots to infiltrate drainage pipes through joints or any minor fractures in the pipes and create blockages, which might result in wastewater overflowing.
- Once tree roots have penetrated the drain field pipes of your septic system, you must seek the assistance of a septic tank specialist who can repair the pipe network.
- While it is critical to maintain the structural integrity of your septic tank, it is equally critical to maintain the structural integrity of your septic system drain field.

How to unclog your leach field
A SHOCK TREATMENT CAN SAVE YOU UP TO $150. The leach field, also known as a drain field, is the area where effluent from the septic tank is disposed of. In this stage of the septic system, a network of perforated PVC drain pipes, crushed stone, and a layer of unsaturated soil are combined to form a septic system. Gravity is typically responsible for the movement of wastewater from the septic tank to the leaching bed. Nevertheless, when the conditions do not permit the use of gravity to transport the wastewater to the leaching bed, a pumping station can be utilized to transport the wastewater to the leaching bed.
Final filtering is carried out by the presence of bacteria and other microorganisms that further purify the wastewater before it reaches the groundwater table.
It does, however, become clogged from time to time.
How is a leach field made?
It is critical that the leaching bed functions well in the wastewater treatment system, and if it does not, the entire system will be adversely affected. It is also critical to prevent structural problems from occurring in the first place by ensuring that the building is designed correctly. As a result, only fully licensed contractors are permitted to do such a project. But, first and foremost, you will need to conduct a percolation test as well as a comprehensive review by an engineering professional.
A quick percolation rate is seen in sandy soils; whereas, a sluggish percolation rate is found in clay soils.
In order for a soil to be considered excellent, its percolation rate should not be too high or too low.
If, on the other hand, it takes more than an hour for the water to settle, this indicates that the effluent is not infiltrating quickly enough, which might result in backflow difficulties.
The findings of the percolation test, as well as the layout of the various components of your property, will be used by the engineer to provide recommendations on the type of system to use and how to install it.
Steps followed when building a leach field
- The moment has come to start digging the trenches after all of the testing have been performed and the building plan has been finalized and approved by the project team. The number of trenches that will need to be built depends on the size of the septic tank and the volume of wastewater that will be released into the leaching field throughout the construction process. Each trench should have the same breadth as the others (approximately 3-4 feet). In addition, the ditches should have a modest downhill slope to them. Following the excavation of the trenches, they should be filled with crushed stone. The crushed stone bed should be at least one to one and a half inches thick and evenly distributed throughout the ditches. This procedure is critical because it enables for more effective drainage of the effluent under the perforated pipes
- Nevertheless, it is not required. The perforated pipes are then laid on top of a bed of crushed stone to allow for proper drainage. Crushed stone is then placed on top of the perforated pipes to ensure that they are securely attached — enough to prevent them from moving or getting misaligned over time. A layer of crushed stone between 1 and 3 inches thick should enough.
- Following that, a geotextile membrane is laid over the crushed stones. When the membrane is in place, soil or dirt cannot slip between the crushed stones and cause a blockage in the leaching bed. If you haven’t already, install a drain line from the septic tank to the leach field pipes. Finally, the trenches are filled with dirt to make them more level and to make the surface of the leach field more consistent in appearance. After that, you may cover the area with a covering of grass. And, at all costs, avoid planting anything else in or near this part of the yard.
How long does a septic leach field last?
Weeping beds should last at least 25 years if they are well-maintained, but they may live much longer or shorter depending on a variety of conditions. The majority of leaching fields collapse as a result of biological or hydraulic overstress. Hydraulic overload occurs when an excessive amount of water is discharged into the septic tank. Consequently, it is advised that duties such as washing be spread out throughout the course of the week rather than being completed in a single weekend session.
When an excessive amount of organic material enters the leaching field, this is referred to as biological overloading.
The only solid waste that should be disposed of in your septic system is toilet paper and human waste (feces).
Because of the high activity of the bacterial flora in your system, Bio-Sol’sSepti +can help to avoid biological overload in your system.
What is clogging your leach field?
The leaching bed, like the septic tank, is not meant to survive indefinitely. All leaching fields will need to be replaced at some point in the future. However, with careful care and maintenance, your leaching bed should last for many years, if not for a lifetime. The leaching bed utilizes aerobic bacteria on the receiving soil to filter wastewater before it reaches the groundwater table, preventing groundwater contamination. These bacteria decompose organic materials and aid in the elimination of viruses as well as the reduction of nutrients in wastewater.
Clogging in the leaching bed, on the other hand, causes this process to be slowed down, resulting in unavoidable environmental contamination.
During the wastewater treatment process, a black, gelatinous layer forms beneath the distribution pipes as the wastewater passes through the leach field. Rather than sludge, this layer is really a biomaterial sludge known as “biomat.” Because the biomat is waterproof, it significantly minimizes the amount of wastewater that percolates into the soil. In most cases, this biomat is formed of organic waste and anaerobic bacteria that have attached themselves to the soil or broken stone. The organic stuff in the effluent provides food for these bacteria.
- Contrary to this, it aids in the further filtering of wastewater by reducing the rate of infiltration and retaining the organic matter before the water is allowed to reach the soil.
- More black gelatinous sludge builds up in the trenches, the more difficult it will be for the wastewater to permeate and subsequently percolate into the soil as a result of the accumulation.
- As soon as sewage begins to back up, it will always flow to the spot that provides the least amount of resistance.
- When this occurs, the objective should not be to entirely remove the biomat from the environment.
It is important to note that good care and maintenance of the system will assist in preventing such an imbalance, which will save you a great deal of headache (like having to unclog your leach field).
How do you know if your leach field is failing?
It goes without saying that the most visible indicator of a failing leaching bed is when wastewater overflows and reaches the surface. The effluent will rise to the top of the soil or, in certain situations, will pour out the end of the trenches if the receiving soil in the leaching bed is unable to absorb any more water from the receiving soil. The most common reason for the effluent to stop flowing is due to an excessive amount of biomatis being created. Check out the following indicators to determine if you need to unclog your leach field:.
Sluggish drains and toilets
Prior to the drain field failing altogether, you may notice that water is draining through the home at a slower rate. The drains will continue to function as long as there is enough space for the water to flow. On the other hand, it is possible that the water is draining more slowly. If you neglect this problem, which is caused by the leach field, the situation will deteriorate over time and become more serious. It is possible that the septic tank will become overflowing and that the water will be unable to penetrate into the earth at all.
Septic tank scents might be detected in the vicinity of the leaching area or within the house itself. Another sign that the leaching field is failing is the presence of rust. Due to the fact that it is so uncomfortable, this is perhaps one of the easiest indicators to recognize. To determine if you are experiencing the rotten egg smell, first check to see if there has been a buildup of organic material in the plumbing system. You may either use an ecologically friendly drain cleaner (such as SeptiDrain) or check your septic tank for abnormally high water levels to resolve the problem.
Sewage backing up in the house
In the case of clogged septic fields, water is returned to them, which causes the water level in the septic tank to rise. Water will back up through the hole in the septic tank or into your home if there isn’t enough room left in the tank. The leach field in your septic tank is almost certain to be the source of the problem if you see an excessively high water level in the tank. The water level in the septic tank should always be at or below the level of the drain pipe that connects the tank to the leaching field.
It is thus required to determine whether the soil has been saturated as a result of recent high rainfall or snowmelt, as well as to determine whether there has been a recent hydraulic overload.
This might explain why the water level is greater than usual. However, if the situation persists, we can conclude that the leaching bed is no longer operating correctly (it is most likely clogged).
Greener and taller grass around the drainfield
In the case of clogged septic fields, water is returned to them, which causes the amount of water in the septic tank to rise. Wastewater will back up through the entrance or into your home when there isn’t enough room in your septic tank to hold it all. The leach field in your septic tank is almost certainly the source of the problem if you detect an excessively high water level in it. When the water level in the septic tank is at its lowest point, the drain line that connects the tank to the leaching field should be at its highest point.
This requires checking to see whether the soil has been saturated owing to severe rainfall or snowmelt, as well as determining whether a recent hydraulic overload has occurred.
Nonetheless, if the problem persists, we can infer that the leaching bed is no longer operating properly (it is most likely clogged).
Puddles of water in the yard
Puddles on the field may indicate that a hydraulic overload has forced water to come to the surface. If this is the case, contact the field superintendent immediately. When a leach field becomes blocked, the pressure builds up, forcing the water to rise. Large amounts of wastewater can practically pool on the ground when released into the environment. If the water smells like rotten eggs, avoid touching it and keep your children away from the area until the scent has been eliminated. There have been instances where perforated pipes in the leach field have either disconnected or broken.
Otherwise, a blockage is more likely to be the source of the problem.
Soil sinking or collapsing over the leachfield
The presence of excessively damp soil where the leaching bed is placed may also be an indicator that the leaching bed is no longer performing effectively, according to the manufacturer.
How to unclog your leach field?
The presence of excessively damp soil where the leaching bed is located may also be an indicator that the leaching bed is no longer performing correctly, as previously stated.
How much does a new leach field cost?
Choosing to repair your leaching bed will almost certainly necessitate the replacement of your complete septic system as well. You will require a fresh percolation test as well as an appraisal by an engineer with appropriate qualifications. When using a standard septic system, you may expect to pay between $5,000 and $12,500 for the installation and maintenance. However, if you require the installation of a more sophisticated system, the cost of the replacement will be significantly higher (between $15,000 and $30,000).
As a result, we highly recommend you to attempt to resolve the problem first by selecting one of the alternative options that have been provided.
