. Even when the soil has been thoroughly tamped, the weight of the tank can result in a sunken appearance after heavy rains or spring thaws.
- Furthermore, why is the ground around my septic tank sinking? soil sinking over septic tank inlet. Your tank might have a leak allowing the soil to fall or get washed into the tank forming a little sink hole in your back yard. A hole or leak in the tank can allow surface water to enter.
Can septic system cause a sinkhole?
On Dangerous Ground Improperly abandoned septic tanks have been known to cause dangerous sinkholes around them, which can cause injury or even death. In 2017, a 75-year old Apple Valley, California man fell into a sinkhole created by an old septic system.
What are the signs of a failing septic field?
8 Signs of Septic System Failure
- Septic System Backup.
- Slow Drains.
- Gurgling Sounds.
- Pool of Water or Dampness Near Drainfield.
- Nasty Odors.
- Unusual, Bright Green Grass Above Drainfield.
- Blooms of Algae in Nearby Water.
- High Levels of Coliform in Water Well.
Can a septic field collapse?
1. Above-Ground Pressure. If you place a large weight over your septic tank or leach field, things can break. Even if you miss the tank, you could still end up driving over the inlet line, leading to a cracked pipe and inconvenient and costly damage.
Can you leave an old septic tank in the ground?
Tanks can be completely removed or they can be destroyed and buried in place. The decision depends on if you plan to use the land for something else, such as a home addition or pool, and need the remains of the tank out of the way.
How do you fix a sinkhole?
Tips for Filling in the Sinkhole
- Clean the area.
- Try to determine the extent of the hole by careful excavation and probing.
- Incrementally fill the depression with fill soil that has a high amount of clay and low amount of sand.
- Continue this process until the depression is filled in.
How do you know when you need a new drain field?
Drainfield pipes that crack open and break rather than clogging up release too much water into the field area. You may notice puddles or spongy and mushy ground over the area. If a technician reports high water levels during a tank inspection, you may need drainfield repairs instead of just a routine pumping.
What is the most common cause of septic system failure?
Most septic systems fail because of inappropriate design or poor maintenance. Some soil-based systems (those with a drain field) are installed at sites with inadequate or inappropriate soils, excessive slopes, or high ground water tables.
What are signs of a full septic tank?
Here are some of the most common warning signs that you have a full septic tank:
- Your Drains Are Taking Forever.
- Standing Water Over Your Septic Tank.
- Bad Smells Coming From Your Yard.
- You Hear Gurgling Water.
- You Have A Sewage Backup.
- How often should you empty your septic tank?
How do you abandon a septic tank?
Abandoning Septic Tanks and Soil Treatment Areas
- Remove and dispose of the tank at an approved site (normally a landfill).
- Crush the tank completely and backfill. The bottom must be broken to ensure it will drain water.
- Fill the tank with granular material or some other inert, flowable material such as concrete.
How long should a septic system last?
Septic System Basics Because it is expensive to replace a septic system, proper maintenance is important. The more proactive you are in maintaining your system, the longer it will last. In fact, septic tanks can last as long as 30 years or more.
Should I remove old septic tank?
It is important to properly abandon un-used septic tanks, cesspools, or drywells. If an old septic tank, cesspool, or drywell is simply “left alone” there may be very serious cave-in or fall-in safety hazards.
Do concrete septic tanks collapse?
However, no matter how well-built, septic tank problems do occur. Issues may arise in older septic systems, but tanks can also fail prematurely and collapse for several reasons. Above-ground pressure– Placing too much weight over your septic tanks is never advisable, as they’re not designed to be load-bearing.
How do you tell if my sewer line is collapsed?
8 Broken Sewer Line Symptoms
- An Odor of Sewer Gas.
- Slow Drains.
- Clogs and Backups.
- Lush, Green Lawn Area.

What happens when septic tank fails?
Septic systems have long been an environmentally-friendly way to recycle household wastewater, but like all systems they can run into problems. A failed septic system can lead to groundwater contamination, sewage ponding in the yard and sewage backups into the home.
Can You Put Dirt on Top of a Sunken Drain Field?
The principal method of disposing of home wastewater in many regions outside of the reach of municipal sewage systems is through septic systems. It is possible to temporarily disguise a problem by putting dirt on top of a leach field; however, the true answer to mending the system involves thorough examination and cleaning, as well as repairs or replacement of faulty components. While a freshly built tank may sink and require a little amount of more dirt to level the grass, the drain field should not require any additional material to be added on top of the soil already present.
A freshly built septic system may require an additional inch or two of earth as it settles into the landscape, but an existing system should not have dirt put over the drain field to prevent it from failing.
About Septic Systems
Homes constructed outside of towns and cities with a municipal sewer system must be equipped with a means of securely disposing of wastewater generated by sinks, showers, toilets, and clothes washers. An effective septic system is almost always the solution. In addition to the tank, which holds the solids and first rush of wastewater, a septic system includes a drain field, also known as a leach field or leach lines, which transports the water away from the house and allows it to soak into the soil.
The grease builds up to the top of the tank.
InspectionAPedia states that up to 36 inches of loose dirt is put over the top of the gravel and pipelines.
Aside from that, surplus water evaporates from the drain field, so leaving the impurities in its wake.
Sinking Soil and New Installations
The soil around and above the tank, as well as the pipes going to the drain field, may settle once a new septic system is installed. It is possible for the soil to get sunken even after it has been well tamped because of the weight of the tank, which might occur after heavy rains or spring thaws. Although covering the inspection and access ports with a few inches of earth to smooth over any uneven places would not harm the septic tank, you should avoid doing so in the future. The drain field, on the other hand, is a different story.
Don’t add any more dirt to the field since it will interfere with the evaporation of any extra water that has collected there.
There is only one exception: if rainfall is puddled on top of the drainage field. The University of Nebraska-Lincolnrecommends putting a little amount of dirt to shallow depressions in order to prevent puddles from accumulating.
Septic Drain Field Sinking
If the sunken area is more like a drain field sinkhole than a sunken region, you may need to have the perforated pipes repaired or replaced, whether they are new or old. The worst-case situation is that the drain field has failed completely and completely. A simple filling up of the sunken portions with soil or gravel will not resolve the issue. It will be necessary to either repair or replace the drain field. It’s possible that a vehicle was driven over the drain field and smashed the pipes, preventing the wastewater from draining all the way to the end of the leach lines and into the sewer system.
Eventually, a piece of the septic system may actually sink, or the soil may wash away, giving the area a sunken appearance.
Compacted soil obstructs this natural process and can result in sinking, wastewater discharge, and pollution of groundwater and neighboring wells, among other consequences.
In addition, only waste water and toilet paper should be flushed down the toilet.
Can a septic tank cause a sinkhole?
Suffocation might result from the force of the displaced soil pressing on your body and blocking your airways. The most deadly scenario is falling into a sinkhole formed by a malfunctioning septic tank. Gases trapped within an aseptic system are extremely deadly, and if one is submerged in them, one will die from asphyxiation. A huge volume of water created by a big number of visitors in a short period of time might possibly overrun the capacity of the tank and drain field if the septic system is suddenly filled with water.
In addition to the foregoing, why is the earth surrounding my septic tank sinking?
Your tank may have a leak, enabling soil to fall into the tank or be washed into the tank, resulting in a little sink hole in your backyard.
All of the water entering the tankhas tanks to go someplace, and it can’t just come back in via the roof.
- Remove the tank and dispose of it at a location that has been permitted (often a landfill). Backfill the tank when it has been totally crushed. It is necessary to break the bottom in order for the water to drain
- The tank should be filled with granular material or another inert, flowable substance such as concrete.
Is it necessary to remove existing septic tanks from the property? Tanks used in an aseptic system will be needed to have all liquid collected and disposed of by a licensed septic maintenance firm, at the very least, in order to comply with the regulations.
All electrical equipment must be removed from the premises and disposed of in accordance with local legislation. By crushing and filling, all tank (s) must be removed or appropriately abandoned in their current location.
Can a Septic Tank Cause a Sinkhole? (It Can Happen to You)
A sinkhole is a hole in the earth that forms when water dissolves the rock and dirt beneath the surface of the ground. Even if you haven’t considered sinkholes as a potential danger in your yard, if you have acquired a home with an existing septic tank, you should be aware of the possibility. Septic tanks are required for many properties, but it is crucial to ensure that they are safe both while in use and after they are no longer required. Leaving a failed or abandoned septic tank in disrepair for an extended period of time might result in a sinkhole.
If you decide to replace your septic tank, you must properly dispose of or fill in the old tanks to ensure that there is no future risk of contamination.
Continue reading to find out how a septic tank can produce a sinkhole and how to avoid this from happening in the future.
Can a Septic Tank Cause a Sinkhole?
If a septic tank is in poor condition or has been abandoned, it has the potential to produce a sinkhole. In the case of a septic tank, for example, if you notice dirt sinking around the tank, it is possible that there is a leak allowing the soil to wash into the tank. This may result in the formation of a tiny sinkhole in your yard. Although it is unlikely that you would fall into one of these little sinkholes, you might easily sprain an ankle or even break a leg if you do. An further and perhaps more catastrophic scenario in which a septic tank might generate a sinkhole is when it is no longer in use.
It is necessary to properly dispose of or fill the old septic tank in order to prevent it from becoming a danger.
Watch the video to learn more.
In light of the possible danger of family members and pets falling into one of these sinkholes or being injured as a result of them, I find this hard to believe.
How to Handle an Abandoned Septic Tank
There are a variety of options for disposing of a septic tank that is no longer in use or is no longer needed. If you just leave it lying there, it might create a problem years down the line and cause a sinkhole to appear. In the first instance, the tank should be removed and disposed of at a permitted location, such as a landfill. You may also entirely smash the tank, but you will need to backfill the space where it was previously located. Another alternative is to leave the tank in its current location; however, you must fill it with a non-flowing material such as concrete to prevent it from overflowing.
An experienced septic company must completely empty the tank before it can be removed from the property. You must also ensure that any electric equipment connected to the septic tank have been disconnected before you can begin removing or filling the septic tank.
How to Tell If a Septic Tank Is Failing
If your septic tank is failing, there are a number of symptoms that will alert you to the situation. You must pay close attention to them since one of the ways in which your septic system might produce a sinkhole is if it malfunctions. Your septic tank will serve you well for many years if it is properly serviced on a regular basis. Failures that are costly and even harmful can occur if the system is not properly maintained, on the other hand. Listed below are some of the warning indications that your septic tank could be failing:
- From the toilets, sinks, and drains, water and sewage are backing up into the house. Water is draining slowly from sinks, baths, and showers. In the vicinity of the septic tank, there is standing water. The plumbing system is gurgling, and you can hear it. There are foul odors emanating from the area surrounding the septic tank. The grass surrounding your septic tank has a vibrant green and spongy texture
- Yet, In the adjacent lakes and ponds, you may see algae blossoming.
If you observe any of these indicators, it is critical that you contact a certified expert immediately. You have the ability to rectify any concerns before they result in a sinkhole or another costly catastrophe.
Having a septic tank is a major responsibility, and it must be maintained correctly. If you are no longer utilizing your septic tank, you will need to properly dispose of it in order to avoid the occurrence of a sinkhole in the future. Sinkholes produced by septic tanks may be quite dangerous, so be sure that you keep up with your maintenance schedule. Posts related to this one:

I’m throwing my 2 cents in on this dead topic since it made me enraged and I wanted to vent. This tile is dreadful; I’ve used this glass in little square styles before and it’s terrible, but herringbone? It’s terrible. I would have simply walked away. There is no way to make it look perfect unless you do what Brickwood Builders suggested, which is to cut each tile separately once you have marked it and pulled it off the silly paper backing. Otherwise, there is no way to make it appear flawless.

Septic Systems – What to Do after the Flood
What is the best place to go for information about my septic system? Please consult with your local health agency if you require further information or support. More information about onsite or decentralized wastewater systems may be found on the Environmental Protection Agency’s Septic Systems Web site. Do I need to pump my tank if the drainfield is flooded or saturated with water? No! Pumping the tank is simply a short-term remedy at the best of times. Pumping it out might cause the tank to attempt to float out of the ground, resulting in damage to the inlet and outlet pipes in the worst case scenario.
What should I do if my septic system has been utilized to dispose of wastewater from my business (whether it is a home-based or small-scale operation)?
Taking extra measures to prevent skin, eye, and inhalation contact with chemicals in your septic system that receives them is recommended if the system backs up into a basement or drain field.
For particular clean-up information, contact your state’s environmental protection agency or the Environmental Protection Agency.
What should I do with my septic system now that the floodwaters have receded? After the floodwaters have gone, there are numerous things that householders should keep in mind:
- Drinking well water should be avoided until the water has been analyzed. Contact your local health department for further information. Do not use the sewage system until the water level in the soil absorption field is lower than the water level in the surrounding area of the home. If you feel that your septic tank has been damaged, you should get it professionally inspected and maintained. The presence of settling or an inability to take water are both signs of deterioration. Because most septic tanks are below ground and entirely covered, flooding does not usually do any harm to them. Septic tanks and pump chambers, on the other hand, can get clogged with silt and debris and must be properly cleaned. If the soil absorption field becomes blocked with silt, it may be necessary to build a completely new system. Septic tanks should only be cleaned or repaired by skilled professionals since they may contain potentially hazardous gases. Inquire with your local health agency for a list of septic system contractors who operate in your neighborhood. Cleaning and disinfecting the basement floor is necessary if sewage has backed up into the basement. To disinfect the area thoroughly, make a chlorine solution by mixing half a cup of chlorine bleach with each gallon of water. After a flood, pump out the septic system as quickly as possible to avoid contamination. Make careful you pump the tank as well as the lift station. This will clear any silt or debris that may have been washed into the system during the rainy season. It is not recommended to pump the tank while the drainfield is flooded or saturated. Pumping the tank is simply a short-term remedy at the best of times. Pumping it out might cause the tank to attempt to float out of the ground, resulting in damage to the inlet and outlet pipes. Do not compress the soil over the soil absorption field by driving or operating machinery in the vicinity of the soil absorption field. Soil that has been saturated is particularly prone to compaction, which can impair the ability of the soil absorption field to treat wastewater and ultimately result in system failure. Before reconnecting the electricity, check for any damage to all of the electrical connections. Examine to see that the manhole cover on the septic tank is securely fastened and that no inspection ports have been obstructed or damaged. Examine the plants surrounding your septic tank and soil absorption field for signs of disease. Damage caused by erosion should be repaired, and portions should be sodded or reseeded as needed to ensure turf grass cover.
Keep in mind that if the water table is high or your sewage system is threatened by floods, there is a possibility that sewage will back up into your residence. The only way to avoid this backup is to reduce the amount of strain placed on the system by utilizing it less frequently.
- What are some of the recommendations made by professionals for homes who have flooded septic systems
- And Make use of your common sense. If at all possible, avoid using the system if the earth has become saturated and inundated with water. It is unlikely that the wastewater will be cleansed, and it will instead become a source of pollution. Conserve as much water as possible when the system is re-establishing itself and the water table is depleted. Prevent silt from entering septic systems with pump chambers by installing a filter. The pump chambers have a propensity to fill with silt when they are inundated, and if the silt is not cleared, the chambers will clog and obstruct the drainfield. While the earth is still damp, it is not recommended to open the septic tank for pumping. Mud and silt may find their way into the tank and end up in the drain field. It’s also possible that emptying out a tank that’s been sitting in soggy soil can cause it to “pop out” of the earth. (Similarly, systems that have been recently installed may “pop out” of the ground more quickly than systems that have been in place for a longer period of time since the soil has not had enough time to settle and compress.)
- While the land is still wet or flooded, it is not recommended to dig into the tank or drainfield area. While the soil is still wet, it is best not to perform any heavy mechanical operations on or around the disposal area. These operations will have a negative impact on the soil conductivity. It is likely that flooding of the septic tank caused the floating crust of fats and grease in the tank to rise to the surface. Some of this scum may have floated to the surface and/or partially filled the outlet tee, but this is unlikely. If the septic system backs up into the home, first examine the tank for an obstruction in the outflow. Floodwaters from the home that are passed through or pumped through the septic tank will produce greater flows through the system. Clean up any floodwater in the house without dumping it into the sink or toilet, and give enough time for the water to recede. This may result in sediments being transferred from the septic tank to the drainfield, which will block the drainfield. Discover the location of any electrical or mechanical equipment in the system that may have been flooded and avoid coming into touch with them until they are dry and clean
- The presence of mud and silt has a propensity to block aerobic plants, upflow filters, trickling filters, and other media filters, among other things. Cleansing and raking of these systems will be required.
4 Things to Do When Your Septic Tank Is Flooded
If your neighborhood has recently been flooded or has been subjected to strong rains, you may discover that your toilet isn’t flushing properly and that your drains are draining more slowly than usual. It is possible that raw sewage will back up into your tub and sink drains. Drains that are slow or clogged may signal that the water table has risen over the level of your septic field and septic tank. If you believe that your septic system has been flooded, there are four things you should do immediately.
- Check the level of groundwater in your area.
- Septic tanks are typically located a few feet below the surface of the earth.
- If you are aware of the location of your septic tank and drainfield, you should check the water level in the area to ensure that flooding is not a concern.
- When there isn’t any evident standing water in the area, use a probe to check the water level or an auger to dig deep into the earth to find out how much water is there.
- If your tests reveal that the water level is higher than the top of the septic tank, you should immediately cease utilizing the tank.
- Until the Ground Becomes Dry When you believe that your septic system has been flooded, contact a septic pumping specialist immediately; however, you must wait until the earth has become less soggy before having your tank drained.
- If a septic tank is pumped out when the earth is saturated, it may potentially float out of its location.
- Following a decrease in the water table level, it is necessary to pump your system as quickly as feasible.
- Approximately 70 gallons of water are flushed down the toilet per person every day in the average home.
The first step is to check for leaks in all of your fixtures. An inoperable toilet flapper or fill mechanism can leak up to 200 gallons per day, creating a backup of water that your flooded septic system doesn’t have room for. Other suggestions for keeping water out of the drains are as follows:
- Prepare meals that don’t require cooking, such as sandwiches. Disposable flatware, such as paper plates and paper cups, should be used. Showers are preferable to baths because they are shorter. Save the rinse water and put it to good use on the plants. Only flush the toilet when absolutely essential
If your clothes washing machine drains into your main sewage line, it can cause a significant amount of water to be discharged into your septic system. Wash your garments at the laundry until the water table begins to fall below the surface. In the event that you must use the washing machine, wash only modest loads and wait a few hours between each load of laundry. 4. Make modifications to your septic system to make it more efficient. After your septic tank has been drained and your house drainage system has been restored to working order, you should make certain modifications to your system in order to minimize flooding problems in the future.
During a septic emergency, the backflow preventer prevents waste water from entering your home or building.
Also, check to be that your yard’s storm drainage does not overflow into your septic field and storage tank area.
When your septic system is inundated, call Eckmayer Inc right away.
Signs of Septic System Failure
- Flooding is occurring in the home as a result of backed up water and sewage from toilets, drains, and sinks Bathtubs, showers, and sinks all drain at a snail’s pace
- The plumbing system is making gurgling sounds. The presence of standing water or moist patches near the septic tank or drainfield
- Noxious smells emanating from the septic tank or drainfield
- Even in the midst of a drought, bright green, spongy luxuriant grass should cover the septic tank or drainfield. Algal blooms in the vicinity of ponds or lakes In certain water wells, there are high quantities of nitrates or coliform bacteria.
Septic systems, like the majority of other components of your house, require regular maintenance. As long as it is properly maintained, the septic system should give years of dependable service. If the septic system is not properly maintained, owners face the risk of having a dangerous and expensive failure on their hands. Septic systems, on the other hand, have a limited operating lifespan and will ultimately need to be replaced. Septic systems that have failed or are not working properly pose a threat to human and animal health and can damage the environment.
It is possible that a prompt response will save the property owner money in repair costs, as well as disease and bad influence on the environment in the future.
What happens when a septic system fails?
When a septic system fails, untreated sewage is dumped into the environment and carried to places where it shouldn’t be. This may cause sewage to rise to the surface of the ground around the tank or drainfield, or it may cause sewage to back up in the pipes of the structure. It is also possible that sewage will make its way into groundwater, surface water, or marine water without our knowledge. Pathogens and other potentially harmful substances are carried by the sewage. People and animals can become ill as a result of exposure to certain diseases and pollutants.
What are some common reasons a septic system doesn’t work properly?
The pipe between the home to the tank is obstructed. When this occurs, drains drain very slowly (perhaps much more slowly on lower floors of the structure) or cease draining entirely, depending on the situation. This is frequently a straightforward issue to resolve. The majority of the time, a service provider can “snake the line” and unclog the problem. Keeping your drains clear by flushing only human waste and toilet paper down the drain and having your system examined on an annual basis will help prevent clogs.
- Plant roots might occasionally obstruct the pipe (particularly on older systems).
- The inlet baffle to the tank is obstructed.
- In case you have access to your intake baffle aperture, you may see if there is a blockage by inspecting it.
- It is essential that you avoid damaging any of the septic system’s components.
- Avoid clogging your inlet baffle by just flushing human waste and toilet paper, and get your system examined once a year to ensure that it is in good working order.
- This may result in sewage backing up into the residence or surfacing near the septic tank as a result of the situation.
- If there is an effluent filter, it has to be cleaned or changed as necessary.
Preventing this sort of problem from occurring is as simple as cleaning your effluent filter (if you have one) and getting your system examined once per year.
It is possible for sewage to back up into the residence when the drainfield collapses or becomes saturated with water.
Additionally, smells may be present around the tank or drainfield.
It is possible that the system was run incorrectly, resulting in an excessive amount of solid material making its way to the drainfield and causing it to fail prematurely.
While it is conceivable that a drainfield will get saturated due to excessive quantities of water (either from enormous volumes of water flowing down the drain or flooding the drainfield), it is not always viable to dry out and restore a drainfield.
A connection to the public sewer system should be explored if the drainfield has failed and it is possible to make the connection.
It will be necessary to replace the existing drainfield if this does not take place. It is possible for a septic system to fail or malfunction for various reasons. Septic professionals should be contacted if your system isn’t functioning correctly.
How can I prevent a failure?
The proper operation of your septic system, together with routine maintenance, can help it last a long and trouble-free life. Assuming that your septic system has been correctly planned, located, and installed, the rest is up to you to take care of. Inspect your system once a year and pump as necessary (usually every 3-5 years). Avoid overusing water, and be mindful of what you flush down the toilet and what you flush down the drain. Learn more about how to properly maintain your septic system.
Can my failing septic system contaminate the water?
Yes, a failed septic system has the potential to pollute well water as well as adjacent water sources. Untreated wastewater is a health problem that has the potential to cause a variety of human ailments. Once this untreated wastewater enters the groundwater, it has the potential to poison your well and the wells of your neighbors. It is possible that oyster beds and recreational swimming sites will be affected if the sewage reaches local streams or water bodies.
Is there financial help for failing systems or repairs?
Yes, there are instances where this is true. Here are a few such alternatives.
- In addition, Craft3 is a local nonprofit financial organization that provides loans in many counties.

Why Do Septic Systems Fail?
You may be wondering how you can tell whether your septic system is failing. To begin, respond to the following questions:
- Do your drains empty slowly for reasons other than old, blocked pipes? If so, you may have a problem. Do you have sewage backing up into your home? Has a damp, stinky patch in your yard piqued your interest? Is your septic tank connected to a ditch or a stream for disposal? Does the water from your washing machine or sink drain into a road or a brook
- Is it common for you to have drainage issues after a heavy rain or when the ground is sloppy? Do you notice a puddle in your yard when you do your laundry? Do you have to pump out your septic tank on a regular basis (more than once a year)? Are there areas of your yard where the grass over or surrounding your septic tank is greener than the rest of your lawn? Has your septic tank or drainfield been moist or spongy for a week or longer despite the fact that there hasn’t been any rainfall?
If you responded “yes” to any of these questions, it is likely that your septic system has failed or is on the verge of collapsing completely. Therefore, it is not handling and disposing of sewage in an ecologically safe and environmentally sound manner. Additionally, unpleasant bacteria (fecal coliforms) or excessive concentrations of nutrients (especially ammonia) detected in both neighboring wells and surface water may indicate that your system is in difficulty. Generally speaking, a septic system has four fundamental components: the source (the house), the septic tank, the drainfield (also known as a leach field), and the soil below the drainfield (Hoover, 2004; Figure 1).
- The sort of system that is employed is determined by the soil and site characteristics of the lot; nevertheless, the conventional system (as seen in Figure 1) is the most typically used in the state of California.
- Overloading a sewage system with more water than it can absorb is a typical cause of septic system failure.
- The surplus water flows back into the house or onto the lawn when this flow rate is surpassed, causing damage to the structure.
- A change in water consumption, such as the addition of more people to the household or the installation of a water-consuming device, such as a dishwasher or washing machine, may cause your septic system to accumulate excess water.
- Each of these devices has the potential to introduce excessive water to your septic system and should not be connected to it.
- Water from roofs, roads, and paved surfaces, in particular, may be channeled onto the system drainfield.
- As a result, sewage backs up into the home or accumulates on the surface of the ground.
As a result, septic tanks are built to be waterproof, and surface water should be channeled away from the septic tank’s access covers in order to prevent flooding.
The North Carolina State Extension publications Septic Systems and Their Maintenance(AG-439-13) and Septic System Owner’s Guide(AG-439-22) provide information on how to properly maintain a septic system in your home.
Assuming that particles do manage to make it to the drainfield, they will block any small holes or pores in the gravel and dirt below, which will result in sewage backing up and flooding the house or surfacing in your yard.
Pumping your tank every 3 to 5 years, depending on how often it is used, is recommended (seeSeptic Systems and Their Maintenance(AG-439-13) for detailed recommendations on pumping frequency).
A trash disposal should not be installed in a home with a septic system.
No evidence exists that additives, whether biological or chemical, have a good effect on the solids in storage tanks or the system as a whole, according to the experts.
After January 1, 1999, your system must be equipped with an effluent filter if it acquired its permit from your county health department after that date.
Maintenance of the filters is required on a regular basis.
Whenever this occurs, the filter may be cleaned with a garden hose, making sure that all of the waste on the filter is rinsed away into the inflow side of the tank, and the filter can be replaced in the tank by a septic tank pumper or the homeowner.
A septic system that has been inadequately built is a disaster waiting to happen.
The amount of area required for a drainfield is determined by the quantity of sewage that flows into the system, as well as the soil and site characteristics around the drainfield.
Nonresidential property has a flow rate that is defined by the type of use that is intended.
On the whole, sandy soils can take more wastewater than clayey soils, resulting in smaller drainfields for sandier soil types.
The soil is the most significant component of a septic system since it is responsible for processing and ultimately spreading the treated sewage in the system.
A restrictive layer that is too near to the trench bottom may also prevent the soil from properly absorbing all of the sewage, resulting in it being forced to the surface or back up into the home, among other consequences.
The vertical separation distance is the term used to describe this distance.

Because of the excessive moisture in the soil, when systems are placed in excavated areas, the soil is severely compressed and the soil pore space is smeared in those locations.
It is likely that wastewater will back up into the home or appear on top of the ground as a result of the reduced ability for wastewater to flow into soil.
This entails inspecting the height of each component on a regular basis.
It is critical that any step-downs or other devices used on sloping sites are correctly built, or else one trench may become overloaded with effluent.
Finally, the soil cover over the drainfield should be consistent and topped in order to prevent surface water from ponding on top of or flowing into the drainfield.
Driving over, paving over, or constructing a structure on top of a septic system can cause damage or destruction.
As a result, the soil might get compacted or ruts can form, exposing system components as well as potentially untreated sewage to the ground surface.
A structure built over a drainfield may cause compaction or even damage to a line as a result of the weight of the structure or the location of the building’s footings, among other things.
Tree roots can clog drain lines and gravel in trenches, causing them to overflow.
Roots may potentially enter the septic tank or distribution box, so avoid planting trees and bushes directly in front of or next to these devices.
The grass aids in the evacuation of water and the prevention of soil erosion across the various components of the system.
If this region were now in use, it should be handled and safeguarded in the same manner.
It is comparable to the lifespan of an asphalt shingled roof, when properly maintained, in terms of lifespan of a septic system.
Any failure, regardless of its source, is a nuisance, represents a threat to public health, and has the potential to pollute the environment.
The department will dispatch an environmental health professional who has received specialized training in examining failed septic systems to discover the root cause or reasons of the failure and to make recommendations on how to correct the situation.
The installation of water conservation equipment, for example, might be sufficient remedial steps in some circumstances. In the event of a full breakdown of the system, the installation of a new septic system may be the only viable option. Repairing a Septic System: Dos and Don’ts
- Reporting issues to your local environmental health department and requesting an examination are both recommended. Dokeep the water turned off until the problem is resolved
- People and animals should be kept away from untreated sewage by cordoning off or fencing off the area where sewage is visible on the ground surface. Don’t pile extra dirt on top of a puddle of water that smells like raw sewage, which is most likely the result of a sewage backup. In addition to not resolving the issue, it may cause sewage to back up into your home. Raw sewage includes hazardous microorganisms that can cause illness or death if not treated properly. Don’t pipe or ditch sewage into a ditch, storm sewer, stream, sinkhole, or drain tile
- Instead, use a drain tile. A threat to human health will result from the contamination of surface water, groundwater, or both. You are not permitted to pipe, ditch, or otherwise discharge sewage into an abandoned well or other hole in the earth. This will contaminate groundwater and pose a health risk to those who live nearby. It is against the law
- Do not overlook the situation. It’s not going away anytime soon. A simple repair may become a very pricey one if you wait too long to address the issue. The longer you wait to address the issue, the worse the situation may get.
The most effective strategy to avoid a septic system failure is to do regular maintenance on it. As previously noted, the North Carolina State Extension publicationsSeptic Systems and Their Maintenance(AG-439-13) andSeptic System Owner’s Guide(AG-439-22) provide information on how to properly maintain a septic system. Some of the actions you can take are listed below.
- Water should be conserved. Reduce the quantity of wastewater that has to be absorbed by the soil by using water-saving fixtures and conserving water in the kitchen, bath, and laundry, among other things. As a result, it is especially useful immediately following a large rain, as well as throughout the winter and early spring
- Fixtures that are leaking should be repaired or replaced. The presence of leaky fixtures causes surplus water to be discharged into the drainfield, reducing the quantity of water that needs to be absorbed by the soil. Continue to provide enough cover and landscaping over the drainfield. Make sure the drainfield is well-covered with grass in order to minimize erosion of the soil. A topped drainfield and surface swales will help to keep excess surface water from entering the trench and damaging the soil. Check to see sure gutters, downspouts, patios, walkways, and roads do not redirect water over the drainfield or septic tank, as well. Fill your tank with water on a regular basis. Keeping the drainfield clear with regular pumping keeps particles from accumulating and clogging it. Depending on how often the tank is used, it should be pumped every 3 to 5 years. It has not been demonstrated that the use of additives can considerably reduce the quantity of solids in a tank. Avoid using them in place of regular septic tank pumping
- Instead, limit the amount of waste that goes into your septic tank. Chemicals, solvents, cleaning fluids, paint, motor oil, gasoline, and other similar items should not be disposed of in a septic tank or drain field. They have the potential to destroy all of the good bacteria in the tank and soil, as well as contaminate the surrounding environment. Dispose of these materials appropriately at a recycling center or transfer station in your neighborhood. The following items should be disposed of in the trash: kitty litter, hygiene products, cooking oil, grease, and leftover food. Compostable waste from fruits and vegetables
- Do not drive or construct over any component of your septic system
- Inspect the system components on a regular basis. Examine the environment for signals of issues that can be rectified before a failure happens.

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. If any of the following apply to your septic tank, it may be necessary to pump it:
- 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.

How a Septic System Works – and Common Problems
This Article Discusses Septic Tanks are a type of septic tank that is used to dispose of waste. Field Sizing and System MaintenanceProblems with the Leach FieldSystem Performance Questions and comments are welcome. See Also: Septic System Frequently Asked Questions Articles on SEPTIC SYSTEM may be found here. In locations where there are no municipal sewage systems, each residence is responsible for treating its own sewage on its own property, which is known as a “on-site sewage disposal system,” or septic system, more popularly.
One of the most commonly seen types of leach field is composed of a series of perforated distribution pipes, each of which is placed in a gravel-filled absorption trench.
The wastewater is collected in the septic tank once it has been discharged from the residence. Septic tanks are normally between 1,000 and 2,000 gallons in capacity and are composed of concrete, strong plastic, or metal, depending on the model. Highly durable concrete tanks, which should endure for 40 years or more provided they are not damaged, are the most common. Many contemporary tanks are designed with two chambers in order to maximize efficiency. Household wastewater is collected in the septic tank, where it is separated and begins to degrade before being discharged into the leach field.
- In the tank, oil and grease float to the top of the tank, where they are known as scum, while solid waste falls to the bottom, where they are known as sludge.
- Bacteria and other microorganisms feed on the sediments at the bottom of the tank, causing them to decompose in an anaerobic (without oxygen) process that begins at the bottom of the tank.
- Solids and grease must be pushed out of the system on a regular basis in order for it to continue to function effectively.
- Each gallon added to the tank results in one gallon being discharged to the leach field, leach pit, or other similar treatment facility.
A large amount of water delivered too rapidly to the tank may discharge untreated effluent, along with oil and particulates, into the leach field, where it may block the field and cause a backup.
When used properly, a leach field (also known as a “drain field”) is a series of perforated pipes that are typically buried in gravel trenches 18 to 36 inches below grade — deep enough to avoid freezing, but close enough to the surface that air can reach the bacteria that further purify the effluent (see illustration below). As little as 6 inches might separate you from the ground surface, depending on your soil type and municipal regulations. It is customary to cover the perforated pipes with approximately two inches of gravel and a layer of topsoil that is 18 to 24 inches in depth.
- Grass is often sown above the ground.
- The leach field is comprised of rows of perforated pipes in gravel trenches that are used to spread wastewater over a vast area in order to further purify it.
- A bacteria-rich slime mat forms where the gravel meets the soil, and it is responsible for the majority of the water purification work.
- Despite the fact that wastewater freezes at a far lower temperature than pure water, freezing is still a hazard in cold areas.
- The leftover pathogens are converted into essential plant nutrients by these organisms, while sand, gravel, and soil filter out any solids that remain.
- If the system is operating effectively, the filtered wastewater will return to the aquifer as naturally clean water that is suitable for human consumption at this stage.
- Alternative systems may be permitted in situations when traditional leach fields are unable to function properly owing to poor soil conditions or a high water table.
- Special systems may also be necessary in regions where there are flood plains, bodies of water, or other ecologically sensitive areas to protect against flooding.
SIZING THE LEACH FIELD
Using perforated pipes put in gravel-filled trenches, the drain field is sized to accommodate the number of beds in the house. In order for the system to function successfully, the leach field must be appropriately sized for the soil type and amount of wastewater, which is normally determined by the number of bedrooms in the house. In order for the liquid to seep into the soil, it must be permeable enough to do so. As a result, the denser the soil, the larger the leach field that is necessary.
- Better to have surplus capacity in your system than to have it cut too close to the bone.
- Septic tank backup into your house, pooling on the surface of the earth, or polluting local groundwater are all possibilities if the ground is incapable of absorbing the liquid.
- Dense clay soils will not absorb the liquid at a sufficient rate, resulting in a backlog.
- If the soil is mostly composed of coarse sand and gravel, it might drain at such a rapid rate that untreated sewage can poison the aquifer or damage surrounding bodies of water.
- Alternative systems may be permitted in situations when traditional leach fields are unable to function properly owing to poor soil conditions or a high water table.
These systems sometimes cost twice or three times as much as a regular system and require significantly more upkeep. Near flood plains, bodies of water, and other ecologically sensitive places, special systems may also be necessary to protect people and property.
SEPTIC SYSTEM CAREMAINTENANCE REQUIRED
If you take good care of your system, you will be rewarded with years of trouble-free operation. Pumping the septic tank on a regular basis is necessary to remove the particles (sludge) and grease layer (scum) that have built up in the tank. The solids will ultimately overflow and spill into the leach field, decreasing its efficacy and diminishing its lifespan if this is not done. The rehabilitation of a clogged leach field is difficult, if not impossible; thus, constant pumping is essential!
- Cooking fats, grease, and particles may also wash into the leach field if the tank is too small for the amount of water being used or if the tank is overcrowded on a regular basis.
- Extra water from excessive residential consumption or yard drainage can overwhelm the system, transporting oil and particles into the leach field and causing it to overflow.
- In addition, don’t try to complete a week’s worth of laundry for a family of five in a single day.
- To minimize overburdening the system, the following measures should be taken:
- Distribute your washing loads and other high-water-use activities across the week
- And In the kitchen and bathroom, use low-flow appliances, faucets, and fixtures. Toilets, in general, are the source of the greatest amount of water use. Water should be diverted away from the leach field from the yard, gutters, and basement sump pumps.
In addition, refrain from flushing sediments, strong chemicals, and just about anything else down the toilet or sink other than biological waste and white toilet paper. Avoid using garbage disposals in the kitchen. If you really must have one, keep it for small non-meat bits only. Avoid flushing chemicals or paints down the toilet since many chemicals can destroy beneficial microorganisms or cause water contamination in the surrounding area. Avoid flushing the following down the toilet:
- Grease, fats, and animal scraps
- Paints, thinners, chemicals, and pharmaceuticals
- And a variety of other materials sanitary napkins, tampons, and other supplies Paper towels and disposable diapers are examples of such products. Egg shells, coffee grounds, and nut shells are all good options. Antibacterial soaps and antibiotics are available.
It is preferable to put grass over the leach field and to refrain from driving or parking in the vicinity. Excessive weight placed on top of the drain field might compress the earth, diminishing its efficiency as a drain field. Drain pipes can also become clogged by trees and plants with invasive roots. In order to prevent damage to the leach field, the following measures should be taken:
- Heavy machinery should not be driven, parked, or stored on top of the leach field (or septic tank). Placement of a deck, patio, pool, or any other sort of construction over the leach field is prohibited. Remove any large trees or other plants with deep roots from the leach field. Grass is the most effective groundcover.
Even with careful use and routine maintenance, however, leach fields are not guaranteed to survive indefinitely. It is inevitable that the soil will get saturated with dissolved elements from the wastewater, and that the soil will be unable to absorb any more incoming water. The presence of an odorous wet area over the leach field, as well as plumbing backups in the house, are frequently the first indicators that something is wrong. Many municipalities mandate septic system designs to incorporate a second “reserve drain field” in the case that the first field fails.
A well constructed and maintained system should last for at least 20 to 30 years, if not longer than that. After a few tears, the initial field will naturally heal and may be used once again when the situation calls for it to be. More information on Septic System Maintenance may be found here.
SEPTIC SYSTEM PERFORMANCE PROBLEMS
Poor original design, abuse, or physical damage, such as driving heavy trucks over the leach field, are the root causes of the majority of septic system issues. The following are examples of common situations that might cause a septic system to operate poorly: Plumbing in the home. obstructed or insufficient plumbing vents, a blockage between the home and the septic tank, or an insufficient pitch in the sewer line leading from the house are all possible causes. Sewage tank to leach field connection Septic tank and leach field blockage caused by a closed or damaged tank outlet, a plugged line leading to the leach field caused by tree roots, or a blockage caused by sediments that overflowed from the tank Piping in the leach field.
Most of the time, tree roots do not make their way through the gravel bed and into the perforated pipe.
Reduced flows, achieved through the use of flow restrictors and low-flow faucets and fixtures, may be beneficial.
Because of the seasonal high water table, the soil around the trenches might get saturated, reducing the soil’s ability to absorb wastewater.
This may frequently be remedied by adding subsurface drains or curtain drains to intercept the water flow into the leach field region and to lower the water table in the immediate area around the drainage system.
