- Within the sand fill is a gravel bed with a network of perforated distribution components, typically PVC pipes. Septic ta effluent is pumped in controlled intervals through the pipes to insure uniform distribution throughout the bed. Final treatment of the effluent occurs as it filters through the sand and into the natural soil.
What is a septic tank field line?
Septic drain fields, also called leach fields or leach drains, are subsurface wastewater disposal facilities used to remove contaminants and impurities from the liquid that emerges after anaerobic digestion in a septic tank. A septic drain field, a septic tank, and associated piping compose a septic system.
How much field line do I need for a septic tank?
A typical septic drainfield trench is 18 to 30 inches in depth, with a maximum soil cover over the disposal field of 36″; or per the USDA, 2 feet to 5 feet in depth.
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 are septic field lines made of?
Leach pipes are usually made of perforated PVC pipe. To encourage the final product to trickle into the soil, the pipes are bedded in gravel and sand or sometimes are covered with plastic septic chambers.
How do I know if my septic field is failing?
The first signs of a failing septic system may include slow draining toilets and sinks, gurgling noises within the plumbing, sewage odors inside, continuing drainage backups, or bacteria in the well water. The area of the strongest odor will point to the location of the failure in the septic system.
What is the difference between a septic tank and a septic field?
The septic tank is a buried, water-tight container usually made of concrete, fiberglass, or polyethylene. The liquid wastewater (effluent) then exits the tank into the drainfield. The drainfield is a shallow, covered, excavation made in unsaturated soil.
How deep is a drain field?
A typical drainfield trench is 18 to 30 inches in depth, with a maximum soil cover over the disposal field of 36 inches.
Can you add dirt on top of leach field?
Never add additional soil over the drain field unless it is a minimal amount used to restore an area that may have been eroded or pulled up by removing another plant. Try not to be overly zealous when tilling the soil for planting. Remember that the drain lines may be as close as 6 inches from the soil surface.
Can you have a septic tank without a leach field?
The waste from most septic tanks flows to a soakaway system or a drainage field. If your septic tank doesn’t have a drainage field or soakaway system, the waste water will instead flow through a sealed pipe and empty straight into a ditch or a local water course.
How do I find my Drainfield lines?
Look at your yard. Although it is common to not have any signs of the drainfield location, look for lines of green grass, dead grass, or depressed areas. These could be signs of your drainfield location. Check for septic records with the permitting authority (usually the county), the installer, or the designer.
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.
Can a drain field be repaired?
There’s usually no repair for a drainfield that has failed. You probably need to replace some or all of your system.
How long should 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.
Can you pump out a drain field?
Septic system back pumping to remove water from a flooded or saturated drainfield is a service offered by some septic contractors. In our opinion back-pumping septic fields is ineffective, possibly harmful, and is not a recommended procedure. It certainly will not fix a flooded nor failed septic drainfield or soakbed.
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:
- There are several signs of a faulty septic system, and not all of them are unpleasant odors. Any of the following signs should prompt you to seek professional help:.
What Are Leach Lines and When Should They Be Replaced?
If your house is equipped with an aseptic system, it will have leach lines or an aleach field. It is necessary to have leach lines as part of any onsite wastewater system since they are the final stage in a process that begins at your sink or toilet and finishes with the wastewater being disposed of in the ground. When the leach lines stop working, the entire system fails as a result. Knowing how to recognize failing or failed leach lines may assist you in catching the problem early and limiting the amount of money spent on replacement.
How a Septic System Works
In order to separate them from municipal or public waste systems, septic systems are also referred to as onsite wastewater management systems. The usage of the phrase “onsite” is important because a home’s septic system and a municipal system perform substantially the same functions. Both systems are designed to treat liquid waste or sewage (also known as effluent) and render it harmless by eliminating the pathogens that are present in it.
- It is through the sewer line that the greywater (water collected from sinks and showers, but not baths) as well as toilet liquid and solid waste leave the residence. It is the sewage line that transports the waste down to the septic tank. The trash begins its journey through the septic tank in the first compartment. Heavy waste items sink to the bottom of the tank, while lighter waste materials such as oils and greases float to the surface, forming a layer of scum. Effluent is sent to the rear compartment by baffles and screens. In order to sink into the earth, wastewater must first pass through an effluent filter and then via leach lines.
Tip
Millions of bacteria live in septic tanks and drains.
The bacteria are responsible for the breakdown of waste in the systems. As a result, a septic system that is excessively clean will be unable to perform correctly. Even two liters of bleach are sufficient to prevent or significantly inhibit the bacteria’s ability to digest waste.
What Are Leach Lines?
Leach lines are referred to by a variety of names, including leach field, leach bed, filter bed, and percolation bed. After passing through the septic tank, leach lines are used to distribute septic effluent into the surrounding soil. Leach pipes are laid out across an open area, generally a backyard, in order to disperse the effluent across the greatest feasible area as quickly as possible. Following its exit from the septic tank, the effluent travels into the leach pipes, trickles out of pores in the pipes, then percolates downhill via gravel and sand, and finally into the surrounding soil.
In order to encourage the final product to seep into the soil, the pipes are either bedded in gravel and sand or covered with plastic septic chambers, depending on the situation.
Signs of Failing or Failed Leach Lines
Sometimes it might be tough to figure out which element of a septic system has failed when one is experiencing problems. Any of the following symptoms can assist you in determining whether or not leach line failure is the source of the problem:
- Plant growth that is more vigorous or grass that is greener than in other parts of the yard
- Throughout the home, the drains are slower to operate
- Water in the house regularly backs up. If your yard is squishy or has standing water, call for help. sewage scents emanating from either inside or outside the home
- Sounds of gurgling
Why Leach Lines Fail
It is theoretically possible to construct an intelligent self-contained system that returns water to the soil and disinfects it biologically. However, in practice, this is not the case. In actuality, because a septic system has so many moving components, anything may go wrong, and leach lines are frequently the cause of these mishaps. If the septic tank was not correctly handled, it is possible that an excessive amount of solid waste was permitted to flow into the leach lines, clogging holes in the pipe or the surrounding ground.
Even if there is no catastrophic occurrence, it is possible that your leach field has simply reached the end of its normal life cycle.
How to Replace Leach Lines
It is recommended that you hire a professional to handle the replacement of leach lines, as is the case with the majority of septic tank tasks and concerns.
- The present leach field must be completely demolished in order to prevent contamination. A large amount of heavy equipment is required for this phase since leach fields are widely distributed. A distribution box is put near the septic tank for the purpose of distributing waste. The wastewater from the septic tank is delivered to the distribution box by a single big pipe. The leach field is formed by lateral pipes that radiate outward in trenches from the distribution box. There are between four and nine lateral pipes in total. Because this is a gravity-based system, the lateral pipes must be installed on a downward slope to be effective. Plastic septic chambers are installed over the leach line pipes to collect the wastewater. The trenches are filled with at least 6 inches of earth, or to the depth specified in your location, depending on the conditions. For the time being, only some parts, such as the ends of the pipes and the distribution box, are visible. The local permitting agency conducts an inspection of the septic system. Following a successful inspection, the remaining trenches are filled up
- Otherwise, they are left unfilled.
Dos and Don’ts of Drain Field Lines
There must be complete removal of all of the components of the current leach field. Heavy equipment is required for this stage due to the broad nature of leach fields. Located near the septic tank, a distribution box is set up. The wastewater from the septic tank is sent to the distribution box by a single big pipe; From the distribution box, lateral pipes spread outward in trenches to form the leach field, with between four and nine lateral pipes per box. This is a gravity-based system, which means that the lateral pipes must be installed on a downward slope.
The trenches are filled with at least 6 inches of earth, or to the depth specified in your region, depending on the situation.
It is necessary to fill in all of the trenches if the septic system passes inspection;
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
On top of them, place something hefty. Due to the fact that compacted soil is ineffective at absorbing wastewater, it is important not to build anything on top of it (patios, gazebos, swimming pools, play equipment), nor to allow anybody to drive over the top of it (roads, parking lots, parking lots). On or around them, you can plant anything other than grass. They have the potential to clog or destroy pipelines. System overloading is a serious issue. Solids may enter the drainfield if an excessive amount of wastewater is introduced into the system at the same time.
System treatments are a waste of money.
As long as you don’t introduce anything that will kill the bacteria in your system, such as antibacterial soaps or chemicals, it will have all of the germs it requires on its own, which is ideal.

Are you curious about the location of your septic lines? It is critical to know where the septic tank is located on a property in order to properly manage and preserve the system. For example, you don’t want to pave over the ground or grow trees too close together in a forest. It is possible to obtain a copy of the septic tank diagram of the drain field, which will give you a fair sense of where the pipes will go. If this is not the case, you may need to attempt some other methods of locating septic drain lines.
The solids and liquids are separated within the tank by a baffle or wall that is built inside the tank.
When pipes get clogged or when drain fields become too saturated with fluids, problems arise.
Locating a Septic Tank on Your Property
Begin your search for the septic tank lines at the residence first. Drain lines from the home’s plumbing should be traced to the septic tank, which is typically located 10 to 20 feet from the home’s exterior. The drain line connects the tank’s end, which is located opposite the house, to the leach field. Check the natural slope of the ground to see whether the leach field may be found there. It is never a good idea to look for drain lines using heavy gear, wrecking bars, or jackhammers. Before excavating, contact your local electric utility provider or gas company to determine the location of underground gas or utility lines.
Plunge the long, thin metal probe into the earth until you can feel it strike the tank and feel the tank’s edges.
Perform Regular Inspection
According to industry experts, you should examine your septic tanks and, if required, pump them out once every three years. If you are experiencing gurgling sounds in your house or water backing up after your system has been repaired, a saturated drain field might be the source of the problem. Drain fields that have been clogged or damaged are unable to be rectified. In order for the septic system to function properly again, you’ll need to have a new drain field installed. Find capped clean-outs that are a few inches vertically above the ground in the leach field itself, or check behind a wall or in a closet in the basement for capped clean-outs.
- You can visually trace the orientation of the pipe from the clean-out if there is no other information available.

- When you are looking for the lines, look for grass or vegetation that greens in stripes when the grass surrounding it browns.
- Putting hot water into your system might cause snow or ice to melt above the drain pipes if the system is not properly insulated.
- If you have a deep system, as is the case for homes with basements, you will most likely not be able to observe natural signs since the drain field is too deep to be seen from above.
- Unless the system was built without a permit, the blueprints or designs for septic system installations are kept on file with the local health authority until the system is operational.
- If your search does not provide any relevant results, you can request a record search based on your street address or the tax account number associated with the property.
- If the agency has a copy of the record, they will mail it to you.
- If you don’t have a drawing of the septic system, you need enlist the assistance of a disposal system contractor or a certified liquid waste transporter to find it.
Another option is to purchase a flushable transmitter from a plumbing or rental business, or you may contract with a tank cleaning firm. The signal from the transmitter is picked up by a hand-held receiver after it has been flushed down the toilet.
Check the Distribution Box
There are certain septic tanks that feature an extra distribution box that is located a few feet from the tank on the tank’s downstream side. Water is channeled into the trenches by ports and pipes in the box. It is recommended that, if your system includes a distribution box, the box’s top be designed to expose the orientation of the ports that connect to the drain field lines. It is feasible to locate the box with a probe, but extreme caution should be exercised. Avoid applying excessive force to the probe, since this may result in damage to the box.
In most cases, individual drain lines run perpendicular to the intake line, but they may also branch into an H-pattern or other patterns that are appropriate for the terrain.
Find the location of your septic drain lines so that you can safeguard the area in and around them with a little detective work.
What You Need to Know About Your Septic System’s Drainfield
In certain cases, an extra distribution box is installed a few feet from the tank on the tank’s downstream side. Water enters the trenches through ports and pipes on the box’s inside wall. Where a distribution box is used, the lid must be designed in such a way that the ports that connect to drain field lines may be seen in their proper orientation. If you use a probe, you should be able to locate the box, but proceed with caution. Excessive force with the probe may cause damage to the box, so exercise caution.
Although the drain line exits the tank parallel to the intake line, individual drain lines may run perpendicular to the intake line or branch into an H-pattern or other patterns that are appropriate for the terrain.

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. Drainfields, much like any other component of your septic system, require regular attention and upkeep.
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
When erected over a drainfield, heavy objects such as a shed, animals, or automobiles can cause the pipes below to get damaged or destroyed. Compaction of the soil can also be caused by an excessive amount of weight on the drainfield. Wastewater cannot be adequately absorbed in compacted soil, resulting in the occurrence of many of the symptoms described above.
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.
7 Ways to Tell When it’s Time to Empty Your Septic Tank
It is essential that septic tanks are properly maintained in order to avoid blockages and potentially hazardous situations. Septic tanks collect waste water from the home, with particles sinking to the bottom and floating on top of the liquid scum on the surface. Bacteria digest and break down the waste, and surplus water soaks into a gravel-filled drainage area outside the tank, known as the “flush field.” Bacteria digest and break down the waste. And the tank’s solid contents accumulate over time, the level of the tank’s solid contents rises.
Some of the indicators that a tank is overflowing are caused by the waste backing up into the septic pipes and blocking them.
- Waste water falls slowly down the drains of the home. An overflowing septic tank is causing problems with all or most of the drains. If only one drain is taking a long time to empty, it is possible that that drain has a separate clog. Restrooms become clogged with sewerage trash. It is possible for sewer waste to accumulate in the shower and tub drains, as well as in the toilet
- Septic lines may be leaking. The pressure caused by backed-up waste in the septic systems might cause the pipes to leak
- The leach field area in the yard is squishy because to the recent rainfall. The water waste from the tank should either evaporate or be absorbed by grass roots to prevent flooding. Squishy patches and pools indicate that the water that is being discharged from the septic tank is not being absorbed by the soil. There’s a strong sewage stink in the air. The odor of sewage is not one that is easily misidentified. The stench of sewage in your bathrooms or yard indicates that the tank is full and cannot store any more waste. In addition to being greener, the grass over the leach field grows at a quicker rate than the rest of your lawn. Plants benefit from the nutrients in septic tank contents, which is why grass grows exceptionally well when nourished by septic waste overflow. The depth of the sludge layer is one-third the depth of the liquid layer, or even deeper. The easiest approach to determine whether or not your tank need pumping is to have it inspected by a competent contractor. He’ll check the depth of the solid and liquid levels in the tank and pump it out before it overflows, if necessary.
Septic tanks don’t require much in the way of maintenance, as long as you take care of the essentials first. Generally speaking, septic tanks should be drained every three to five years, but they should also be examined once or twice a year to ensure that they are in proper operating order.
Inquire with a trained specialist about the condition of your tank, and he or she can determine how often it should be pumped. To get answers to your questions, get in touch with the Pink Plumber right away. OUR EXPERT PLUMBERS ARE AVAILABLE TO HELP YOU.

How a Septic System Works – and Common Problems
This Article Discusses Septic Tanks are a type of septic tank that is used to dispose of waste. Field Sizing and System MaintenanceProblems with the Leach FieldSystem Performance Questions and comments are welcome. See Also: Septic System Frequently Asked Questions Articles on SEPTIC SYSTEM may be found here. In locations where there are no municipal sewage systems, each residence is responsible for treating its own sewage on its own property, which is known as a “on-site sewage disposal system,” or septic system, more popularly.
One of the most commonly seen types of leach field is composed of a series of perforated distribution pipes, each of which is placed in a gravel-filled absorption trench.
SEPTIC TANK
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.
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.
- 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.

Common Septic Tank Problems and How to Fix Them
In the absence of professional plumbing training, it can be difficult to evaluate whether or not you are experiencing problems with your septic tank. If you live in a rural region, your septic tank may be your only means of treating and disposing of the waste generated by your household. The waste from your home is dumped into a septic tank leach field, which is also known as a septic drain field, once it has left your home. An underground facility designed to remove contaminants from the liquid that emerges after passing through the septic tank, the septic tank leach field is also known as a septic tank treatment field.
If you are unsure about the location of your septic tank, consult with a professional. Fortunately, there are various symptoms that suggest that the leach field of an aseptic tank or the septic tank itself is malfunctioning. Some of these warning indicators are as follows:
- There is backup in your home’s drainage system or toilets. Backups and obstructions are most commonly caused by a septic tank that hasn’t been emptied in a long time, according to the EPA. A failed leach field in your septic tank means that the water that leaves your home will not be handled and treated at all. Your drains will become clogged as a result. The toilets in your home are taking a long time to flush — If all of the toilets in your home take a long time to flush, it might be a sign that your septic tank is overflowing. Due to the fact that this sludge is not being handled by your drain field as efficiently as it should be, it is creating delays in your toilet flushing. It takes longer for sinks and baths to drain now than it used to – A clogged septic drain field may be to fault if your sinks or bathtubs aren’t emptying as rapidly as they should be under normal circumstances. A septic drain field replacement may be necessary if you find yourself waiting an excessive amount of time for the tub to drain after a bath or for the sink to empty after cleaning dishes. It is discovered that there is standing water near your drain field or septic tank – The presence of standing water near your drain field or septic tank is the most obvious indication that your septic tank has been flooded and that your septic leach field is failing. Water remains in your septic tank after it has been cleaned and processed, and this is what causes standing water in your yard. Your septic tank and drain field begin to smell foul near your house or business — Both your septic tank and septic drain field should be free of foul odors, both outside and within your home. Carbon dioxide, methane, and hydrogen sulfide, all of which may be present in household garbage, are responsible for the scents you are smelling. In the vicinity of your leach field, you may notice a strong rotten egg stench, which may signal that sewage is seeping. Your health and safety, as well as the health and safety of others, are at risk as a result of this. You should contact a septic drain field replacement company as soon as possible at this point.

Signs That Indicate you Need an Immediate Drain Field Replacement
So, how can you determine whether you require a septic drain field replacement rather than only a repair? The following are indications that you require an emergency drain field replacement:
- Septic tank failure due to a failure to clean or pump waste out of the tank on a regular basis – If you don’t follow your septic tank cleaning plan, you run the danger of having a septic drain field replacement sooner rather than later. Maintaining your septic tank and having it examined at least once every three to five years helps ensure that your drain field is functioning correctly. The number of people living in your home, whether or not you have a garbage disposal, whether or not you use water softeners, how many guests will be in your home at the same time, how often you do laundry, and whether or not you have a sewerejector pump all influence how often you need to have your septic tank pumped. This one is rather self-explanatory: you have broken pipes in your drain field. If your plumber is checking the pipes leading to and from your leach field and detects a break in the pipes, you will need to have a septic drain field replacement performed immediately. In the event of a septic pipe break that cannot be repaired, new pipes or a complete system may be required. Lack of oxygen in the septic tank as a result of a significant amount of grease – An excessive amount of grease in your septic tank system results in the formation of a “scum” layer. It is possible that your leach field is being replaced. Following an overabundance of grease being dumped into your septic tank, the drain holes and piping leading to your drain field will get clogged, necessitating the replacement of the whole system. Tree roots placing strain on your drain field piping — When tree roots begin to grow into your drain field piping, it might spell doom for your drainage infrastructure. These tree roots have the ability to develop swiftly and will seek out a source of water as soon as they can. If the pipes delivering water to your leach field are large enough, the tree roots will eventually find their way there, perhaps rupturing the piping system. Compaction of soil caused by heavy machinery or automobiles near your septic tank drain field – Drain fields that are close to air pockets in the soil surrounding them. When heavy equipment or automobiles are parked or put on top of or near the leach field, it can cause issues for the system to malfunction. A compacted soil environment encourages water to collect near your septic field.
Common Septic Tank Problems and How to Fix Them
You probably don’t give much thought to what happens to your extra water after it has been flushed down the toilet unless anything starts to go wrong with the plumbing. It is critical that you do thorough septic tank repair on a regular basis in order to minimize costly damage. You must first locate your septic tank before proceeding with any further steps. Due to the complexity of your septic system’s operation, and the fact that much of it is underground, issues with it can often go undiagnosed for extended periods of time.
Most likely, one of these five factors is to blame for any septic tank issues you’re now experiencing.
Clogs in Your Septic System
In order to determine whether or not you have a septic tank problem, remember back to the last time your tank was cleaned. Septic tanks accumulate waste over time, and grey water drains through your septic tank to drain pipes that are buried underground in the earth in your yard. In the event that your tank becomes overflowing, you may begin to notice that your drains are becoming slower and that your toilet is becoming backed up. Each and every source of water in your home passes through your septic system before being used.
- If you have had your septic tank drained within the last year or two, you will most likely not need to have it pumped out again.
- If you notice that all of your drains are draining slowly, you most likely have a clog in one of the lines that drain away from your property.
- Because the diameter of these pipes ranges from 4 to 8 inches, they are likely to be thinner in certain regions than others.
- You may be experiencing some sewage backup into plumbing fixtures in your house or accumulating near your septic tank if your drains are working properly but you’re not sure what’s causing it.
- It’s possible that the problem is in your septic tank’s entrance baffle, which you should be able to see if you have access to this area of the tank.
If there is a blockage in this baffle, you should be able to tell immediately. In certain cases, pushing the clog via the access port may be sufficient to clear it out. If you’re unclear of how to access any of this, you should seek the advice of a professional plumber.
Tree Roots are Infiltrating Your Pipes
Tree roots that are in the way of a septic tank’s operation can also be a source of problems. Whether sewage is beginning to back up into your drains, there are inexplicable cracks in your driveway and sidewalk, or you notice persistent puddles and damp spots in your grass even when it hasn’t rained, it is possible that roots have penetrated your plumbing system. Roots may develop fractures in your drain pipes, and if they continue to grow over time, these fissures can expand and cause significant damage.
The installation of modern, plastic pipes that are capable of withstanding root damage can help you avoid the problem of root penetration.
Root growth inhibitors are also recommended if you have trees near to where your pipes are located, since this will prevent them from growing.
You should chop down any trees whose roots are penetrating your pipes and remove the stumps in order to prevent roots from sprouting back after you’ve cleaned out your pipes if you are able to bear the thought of doing so.
Leaks in Sewage Tank or Lines
Many homeowners dream of having lush, green grass, but if your lawn is vibrantly green but the plants around it are dead, it might be an indication of a septic tank leak, according to the American Septic Tank Association. Experiencing unexplained green grass might also be an indication that your septic tank is pumping out an excessive amount of water, soaking your yard. Moreover, there may even be sewage accumulating in your yard in this situation. This is an issue that should be addressed by a plumbing specialist as soon as possible in order to minimize any potential health risks and costly damage to your property.
IncorrectSeptic Tank Installation
The proper installation of a septic system allows the system to operate smoothly. Know if the firm who built your septic system done it in an accurate and timely manner? Most likely, if you bought an older property, you have no idea who built the septic system in the first place. Furthermore, because you can’t look into your septic system, you have no idea what’s going on down there as well. Failure to bury the tank deeply enough, installing the incorrect-size tank, or utilizing the incorrect soil in the drainfield are all examples of installation problems that can result in septic tank failure.
Increased Water Use
Before it overflows, your septic tank can only contain a certain amount of water. Septic tanks can collapse if there is a high number of people who depend on them for their water. If you have a big family, expect a significant number of long-term guests, or often hold parties, you should get your tank examined to ensure that it is the proper size. If this is the case, you may need to consider upgrading to a larger tank. Your septic system is capable of withstanding a lot of abuse, and it should continue to function well for many years provided it is properly maintained.
If you see any indicators of septic tank difficulties, such as clogged pipes, root infiltration, or sewage leaks, act promptly and call The Original Plumber for a septic tank check to ensure that any problems are resolved as soon and efficiently as possible.
