The Dangers of Paving Over Septic System Components – Septic Maxx

An aerobic treatment system, composting waste, and a drip system are all options for replacing a septic tank.

Paving Over Your Drain Field

Drain fields are hazardous in and of themselves, let alone when paving over them, which is extremely perilous. When you drive over or park in your drain field, you are interfering with appropriate evaporation and increasing the likelihood of soil compaction taking place. A situation in which the earth collapses as a result of excessive pressure nearly usually results in the crushing of pipework is called soil compaction. If you drive or park anything that is heavier than a child’s bike on or over a drain field, you will almost certainly incur expensive repair bills.

Consider placing a 4,000-pound automobile or a 6,000-pound truck on top of the pavement, just to be sure it isn’t already too heavy.

Unlike septic tank repairs, which can be completed by merely replacing the tank, drain field repairs need the replacement of the whole system, which can cost up to $10,000.

Paving Over Your Septic Tank

It is never a good idea to pave over your septic tank. Although soil compaction is not a big concern when it comes to septic tanks, there are additional risks associated with installing an unsecured septic tank below concrete or heavy vehicles. The usage of certain materials and structures is required for the safe paving of over septic tank areas. Due to the fact that the great majority of tank manufacturers do not include such safety elements in their septic tanks, they are more prone to bursting under pressure.

There have been occasions in which septic tanks have collapsed, resulting in significant damage or death.

Do not pave over septic tank components in order to maintain your own safety and the correct operation of your septic tank.

Implementing the usage of environmentally friendly septic tank additives from Septic Maxx will help to advance that endeavor.

In addition, as an Amazon Associate, I receive a commission from qualifying orders. The topic of whether or not it is possible to build a patio over a septic tank is one that we receive frequently from homeowners. The practice of constructing directly on top of an existing septic field is not encouraged unless you have first sought permission from your local building department.

When constructing a structure on top of an existing septic system, things may and frequently do go wrong.

A good rule of thumb is that nothing should be constructed that might obstruct or inhibit the free flow of water into and through your septic system.

Depending on the soil type, putting a French drain around your septic field may be the best alternative if you don’t want to relocate your septic field.

Can You Build A Patio Over A Septic Tank?

When it comes to creating a patio, one of the most often asked questions is “can you build a patio over a septic field?” In the case of this question, the answer is no. For the simple reason that the weight of the concrete in the foundation will put too much pressure on your septic system, which can result in floods or a broken septic tank, it is necessary to do so. The weight tolerance of a septic tank or leach field is extremely low, and even a small amount of weight can cause the tank or leach field to fail.

  1. However, if you already have a patio and want to expand it, there are several options available to you.
  2. The weight will be significantly reduced, and the appearance will be identical to that of other patios constructed of concrete or brick pavers.
  3. Add a pier and beam foundation under your current patio slab as an alternative to a concrete slab.
  4. They will most likely be able to provide you with some guidance on how to go about installing such a feature without endangering yourself or anybody else who may be utilizing the amenities situated under the surface.

Can You Put Pavers Over A Septic Tank?

A septic tank should not be covered with pavers, and doing so may be a violation of your state or municipal construction rules, according to the EPA. Septic tanks are capable of withstanding just a little amount of weight without being harmed, and you’ll require access to the tank in the future. A septic tank is not designed to support a large amount of weight, and it can be destroyed if it is overloaded. Building a deck over the top of your septic tank may potentially cause issues in the future since you will need access to the tank in order to monitor or maintain it.

Tanks, pipelines, and absorption fields are among the components of this system.

As long as you reside in a jurisdiction that needs them, your local health authority will check the installation before issuing a building permit for any house construction or renovation work that may have an impact on the system’s operation in the future.

Can You Build a Deck Over a Septic Field?

The construction of a deck on top of a septic field is not recommended since it will hinder the effluent from naturally draining and dispersing. This can cause damage to your septic system as well as the release of unpleasant aromas into the air around your deck area. It is possible that the evaporating wastewater will corrode the deck from below. There is nothing worse than spending time on a deck that smells like a sewer! Consider installing the deck over a part of your yard that isn’t currently being used for anything else if you have a septic field on your property.

Also, make sure to allow enough of space around your pipes and septic tank so that personnel can readily reach them in the event that repair is necessary in the near future.

They may be able to accomplish this without interfering with the drainage of the field.

Also, consult with a septic tank pumping firm to learn about potential solutions to problems that may occur in the near future. Better than having an expensive deck fall apart because the earth beneath it has been contaminated by effluent runoff!

Rules and Codes Regarding Septic Tanks

Because it will prevent the effluent from naturally draining and dispersing, you should never construct a deck over a septic field. This can cause damage to your septic system as well as the release of unpleasant aromas into the air around your deck area. It is also possible that the evaporating wastewater will rot the deck from under the surface. It’s impossible to enjoy time on a terrace that smells like a sewer! Consider installing your deck over a section of your yard that isn’t currently being used for anything else if you have a septic field on your property.

Maintaining your pipes and septic tank should be done with plenty of space around them to ensure that employees can readily access them if any maintenance is necessary.

Some of them may be able to do so without interfering with the field’s drainage.

Also, consult with a septic tank pumping firm to learn about potential solutions to problems that may occur in the future.

How Much Weight Can Go On Top of a Septic Tank?

Generally speaking, when it comes to an old-fashioned steel septic tank, the answer is “not much at all.” Modern septic tanks are often constructed of concrete, which makes them far more robust. Some versions have a “traffic rating” and axle weights, whereas others are just heavier. Most people, on the other hand, advise against parking on or driving across a septic tank in any situation. The collapse or partial collapse of a building or structure can create major accidents, resulting in significant harm to the driver, the car, the tank, and the surrounding environment.

If you are installing a new one, be certain that it is constructed of sturdy concrete and that it fits all of the requirements.

If the drain field (also known as a leach field) is destroyed, the drain lines that run from the tank will be damaged as well, and you don’t want that to happen.

No one should be able to park in such location if it is clearly marked off.

What Can You Put Over A Septic Tank?

The quick answer is that there isn’t much.

Septic tanks are constructed to be watertight in order to prevent water from leaking out of the tank and entering the surrounding soil. The following is a list of items that may and cannot be placed over a septic tank:

Was wondering what you could put over a septic tank.

r/HomeImprovement – looking to pave (asphalt) my driveway, but the septic tank is under there, anyone deal with this?

My house is situated on a narrow property that is approximately 75′ wide and 225′ long. My existing driveway is made of gravel and is in desperate need of repair. The driveway leads to a two-car detached garage at the rear of my home, which is around 150 feet away. I’d want to have an asphalt driveway built for my home. Having spoken to a former owner, I was advised that, while the septic tank is relatively recent (it was placed by the owner before him about 1990), it is located beneath the driveway around 15′ in front of the garage.

As a result, I have to presume that whomever erected the septic tank did so with the knowledge that it would be driven over, but I don’t want to jump to any conclusions just yet.

Is it necessary for me to contact a septic firm separately and have them analyze the situation?

I’m aware that there are access ports somewhere in my driveway that would need to be maintained, which is OK, but I’m more worried with being able to have an asphalt driveway constructed that is safe to use.

Building Near and Over Septic Tanks

Posted on a regular basis In most cases, minimum setback rules imposed by the Texas Commission on Environmental Equality (TCEQ) preclude the building of a new residence from occuring over any point of an existing sewage disposal system. Foundations, pools, property lines, wells, and other structures must be kept at a certain distance from the septic tank and drainfield in order to meet these setback requirements. It is possible that some homeowners will install objects such as patio decks or house additions over their systems, whether by accident or design.

Building over septic tanks

Construction of a building over any section of your septic system is not recommended. The most typical issue we see is when someone wants to pump out their septic tank but is unsure of where their tank is situated on their property. Tanks hidden beneath a hardwood deck, pool patio, driveways, or even room extensions are not unusual for us to discover and investigate. The majority of the time, this occurs because the homeowner is uninformed of the tank’s location and/or does not have a plan in place for future tank maintenance.

However, in this scenario, the homeowner will be able to pump out their septic tank because no permanent constructions should be constructed over any component of the system.

Building over drainfields

In order for the drainfield to function, water in the solids and some evapotranspiration must be absorbed. In order for bacteria in the soil beneath a drainfield to treat wastewater from a drainfield, the soil beneath the drainfield must have sufficient oxygen. However, if a permanent structure is constructed over a drainfield, it has the potential to reduce the amount of oxygen that can be absorbed by the soil and hence reduce evapotranspiration. The potential of causing the drainfield lines to collapse is a significant concern when constructing over them.

Depending on the age of your system and the restrictions of your local authorities, repairing or shifting your drainfield may need the installation of a whole new system.

  • Amount of distance from the home
  • Basic safety concerns
  • Suggestions for a successful installation

For those who don’t have access to a municipal sewer system, an alternative solution, such as a septic tank and field lines, will be required. The design and operation of these systems are fairly straightforward. When designing a septic system, you must keep in mind the requirements of local construction codes as well as public health concerns.

Tip

Depending on where you live, local ordinances and regulations that specify the distance between the septic tank and the home vary. However, the normal minimum distance is 10 feet between the two structures. Consult your local ordinances and regulations for a detailed answer as to how far your septic tank must be installed from your home. Requirements differ from one location to the next, although the standard minimum distance from the home is 10 feet in most cases. In the case of a private well for drinking water, however, keep in mind that many state departments of health require a minimum distance of 50 feet between a new septic tank and a well.

It is possible that the septic tank will be placed considerably closer to the structure since it will be easier and require less plumbing in some cases.

Basic Safety Considerations

If you’re the type of person who prefers to do things on their own, there are some important precautions you should take before starting this project. Before you start digging the hole for the tank, call your local utility companies to find out where the service lines are located. A gas line, water line, phone line, or electrical connection that has been severed is not only potentially dangerous, but it may also be extremely expensive to repair. Once you have finished excavating the hole, proceed with caution.

It’s also important to understand that a concrete septic tank can weigh up to 5 tons.

Make sure the hole is ready when the tank is delivered so that it can be placed directly in the desired location.

Tips for a Successful Installation

Plan ahead of time to get your water supply switched on prior to installing your septic tank. You must fill the tank with water as soon as it is placed in its final position for this to be possible. This has absolutely nothing to do with the septic system itself, but it is a prudent precaution. In the event of a heavy downpour, the groundwater may swell and a septic tank may float out of the ground, even if it has been buried. If this occurs, contact a qualified professional immediately. Repairing any damage done to the lines or to the tank itself, as well as putting the tank back in its original location, may be a costly and time-consuming endeavor.

Initially, you may be confident that you will remember the exact location of the marker when it is time to top up the tank — which is generally every three to five years — but your memory may fade over time.

In the absence of a marker, you may end up digging holes in the wrong place when it is time to service the tank.

How Far Does A Septic Tank Have To Be From A House

Has it occurred to you that you need to install a new septic tank for your house, or that you are constructing and planning your ideal home for the first time? In either case, you must ensure that your septic tank is installed in the proper location so that it can perform its functions without interfering with the operation of the house. Septic tanks or fields must be located at least five feet away from your residence. In most circumstances, however, tanks are situated even further away from the house, often around 10 feet away in most cases, while leach fields are located approximately twenty feet away from the house.

How Far Does a Septic Tank/Field Need to Be From a House?

When it comes to installing a septic tank or field, you must make sure that it is at least five feet away from your home’s foundation. In most circumstances, however, tanks are situated even further away from the house, often around 10 feet away in most cases, while leach fields are located approximately twenty feet away from the house. This is due to the fact that placing a septic tank too near to where the home will be built might cause construction to be delayed, and because constructing over a sewage tank can be hazardous.

The fact that the septic tank will be located further away from where the new house will be constructed will make the construction process much easier in the upcoming months than it would be otherwise will alleviate many of these concerns for you.

It shouldn’t matter if the leach fields are far enough away and there isn’t anything constructed over them; your system should still function properly.

How Far Does a Septic Tank Have to Be From a Well?

When it comes to septic tank installation, there should be no other water sources nearby that might interfere with the process. As a result, if you have a well that is within sight of your home, you must make certain that the tank and the field are located a sufficient distance away from it. So, how far away does it have to be in order to be considered? This might vary depending on the situation, but there are certain general guidelines that you can follow. The health and safety standards in most states demand that any waste containers, including septic tanks, be at least fifty feet away from any wells in order to ensure public health and safety.

It is crucial to note, however, that this is a rule that may differ significantly depending on which state you reside in and how strict the regulations are.

That particular number will be the one you must follow if your state has a rule that dictates that you have the tank or fields at a greater distance from the house.

How Far Does a Septic Tank Need to Be From a Property Line?

A septic tank must be built in a location that is sufficiently remote from a property line before it can be used effectively. In order to guarantee that the tank is positioned at a sufficient distance from the property line, you must measure such that it is at least 10 feet away from the boundary. This is mostly due to the fact that the tank and drain fields should not be located in an area where a large number of people will be walking. If your neighbors come by and stroll about your property, they shouldn’t have to deal with the issue of something happening to the drain fields because they had to go to grab their dog or because they wanted to drop something off on your doorstep while they were there.

If this occurs and the liquid escapes onto municipal property, you may be penalized for failing to keep the liquid a sufficient distance away from city property.

In most cases, you should keep your pets at least 10 feet away from the property border, but you should double-check with your state’s requirements as well.

Where Should a Septic Tank Be Placed?

Consider the surrounding area while considering whether or not to install a septic tank on your property. You should consider all of the available space. This location should be around 5-10 feet away from the home and property border, 50-100 feet away from a well, and it should be on level ground as well. According on the location of your home, it may be difficult to install a septic tank on your property. Because the soil surrounding the home is rocky or mixed with gravel, it is possible that finding a suitable location for the tank will be more difficult in this situation.

  1. There are a number of other considerations that will influence where you can locate and install both the septic tank and drain fields.
  2. As a result, if your house is constructed on a slope or steep hill where the earth is not as deep in some sections, the tank will not be able to be placed close by and will have to be positioned further away.
  3. When you have a septic tank, you don’t want to have to worry about spillage, and level soil is necessary to avoid this.
  4. There is a lot to look for, especially when distance rules are taken into consideration, but you will most likely engage pros to perform the work for you, making the job much easier.

They will also be able to confirm that the distances between the locations are sufficient to comply with state standards.

How Much Land Is Needed for a Septic Tank?

Your property must have enough open space for the tank to be able to be installed safely and securely there. If the available space is insufficient, you may be unable to incorporate it into the soil. But how much land do you need to put a septic tank on in order to do so? The typical lot size required for the installation of a septic tank and field is around half an acre. This gives you the space you need to find the best location for the tank itself as well as a location for the drain fields as needed.

This is something that you absolutely do not want to have to deal with, so it is preferable to have the space in the first place in order to try and make the best of what you’ve been given.

Conclusion

Installing a new septic tank on your property is a major undertaking that must be completed correctly the first time. It is important to understand the project’s ins and outs, even if you have specialists complete the job on your behalf, so that you are certain that all state and federal rules are being followed. In order to avoid having any difficulties with your septic tank or drain fields in the future, and to avoid being fined or having to pay to have it fixed later on, you should take the following steps: As a result of the restrictions outlined in this article, you may construct your septic tank and drain field in accordance with state requirements, transforming your property into the ideal location for a home or transforming your existing home by constructing a system around it.

You may have your septic tank system installed and connected in a matter of hours, no matter how you go about doing it.

Can you put pavers over septic tank?

If you want to install pavers over a concrete septic tank, you can probably lay them over the top of the tank’s lid as well. The concrete tanks are typically capable of withstanding roughly 10,000 pounds of pressure. Building on top of septic tanks is prohibited. Construction of a building over any section of your septic system is not recommended. Tanks buried beneath a wooden deck, pool patio, driveways, or even room extensions are not unusual for us to discover and investigate. Aside from the aforementioned, is it possible to construct a fence around a septic tank?

  1. Many often, homeowners are unaware that they have a septic system installed and begin constructing patios, decks, and fences in their backyard without considering where their system is placed in the first place.
  2. Herbaceous plants, such as annuals, perennials, bulbs, and decorative grasses, are typically considered to be the finest alternatives for usage on an asepticdrainfield because of their ability to tolerate high temperatures.
  3. Is it possible to drive across a leach field?
  4. Although it is not suggested, driving in small groups of light cars should have no negative impact on a properly designed leach field.

Any excessive packing of the ground over the distribution lines, on the other hand, will have a detrimental influence on the efficacy of the system under rainy conditions.

Can I put a patio over my septic tank?

Asked in the following category: General The most recent update was made on May 23, 2020. Septic tanks are being built on top of them. Tanks buried beneath a wooden deck, pool patio, driveways, or even room extensions are not unusual for us to discover and investigate. It is recommended that no permanent structures be constructed over any component of the system, although in this situation the homeowner can pump out their septic tank. The construction of a deck over an unlined septic field is not ideal, but it is achievable provided the builder follows a few guidelines.

  1. Additionally, what can you place on top of a septic tank to keep it from overflowing?
  2. Aside from the aesthetic benefits, ornamental grasses have the additional advantages of having a fibrous root structure that retains soil in place and provides year-round cover.
  3. You can install pavers over a concrete septic tank, and if you want to, you can probably put them over the tank’s lid as well if you want to.
  4. What is the maximum amount of weight that may be placed on top of a septic tank?

Septic tank found under driveway – what are my options?

I’m not really sure what is going on with the OPS. According to the description, he is “taking a look at a house.” Is it to make a purchase, perhaps? If the OPS is considering acquiring the house, he will, of course, want a thorough assessment of the septic system to ensure that it is in conformity with all applicable laws and regulations. I’m not sure where the OPS is located, but where I live (Massachusetts), a septic system examination is required and must be paid for by the home’s owner before the house can be sold.

Again, I have no clue where the Office of Public Safety is situated, but the Board of Health is the best location to begin your search for septic system installation data.

Because it was clear from what was described about the process that the first three companies had no idea where the tank was, it is reasonable to assume that either there are no plans on file, or that they failed to review the plans before beginning their search, or that the plans on file were not accurate.

  • The statement that any tank under a driveway must be engineered to sustain the weight of a vehicle, and not only of a car but of a heavy load such as a dump truck, is correct in this instance.
  • It is probable that your local regulations may differ.
  • If there are any plans on file, have a look at them.
  • Instruct the inspector to create a documented cost estimate for bringing the system into conformity with current industry regulations.

If you are still interested in the property, you should negotiate a price that is reasonable in light of the work that will be required to bring the system up to code.

Can You Build a Patio Over a Septic Tank?

I’m not really sure what is going on with OPS. “He’s looking for a house,” according to the description. Is it to make a purchase? Obviously, if the OPS is considering acquiring the property and wants to ensure that the septic system is in conformity with local requirements, he would want a thorough assessment of the system performed. I’m not sure where the OPS is situated, but where I live (Massachusetts), a septic system examination is required and must be paid for by the seller prior to the sale of the home.

  • Again, I have no clue where the Office of Public Safety is situated, but the Board of Health is the best place to start if you want to look into septic system installations.
  • In accordance with the process’s description, the first three firms had no clue where the tank was, implying that either there are no plans on file, or that the companies failed to study the plans before commencing their search, or that the plans on file were not correct, respectively.
  • The statement that any tank under a driveway must be constructed to sustain the weight of a vehicle, and not only of a car but of a heavy load such as a dump truck, is correct in its application.
  • It is probable that your local laws may differ.
  • Take a look at any plans that are currently on file.
  • Instruct the inspector to create a documented cost estimate for bringing the system up to current industry standards.

Cost of Septic Tank Repair if Damaged

In order to determine the cost of a septic tank repair, the size of the tank, the type of tank you have, and the region of the country in which you reside must all be considered. It will typically cost between $3,280 and $9,550 to replace it on average. This will be in addition to the costs of refinishing the patio and other outside improvements.

Overall, this is something that you will want to avoid paying for, and it may be possible to prevent it if you construct a deck over the tank instead, and ensure that the weight of the deck is well distributed.

Can a Deck Be Built Over a Septic Tank Instead?

Even though it is safer to install a deck over an existing septic tank than it is to create a patio, it is preferable to utilize a patio option wherever possible. The footings of the deck will need to be deliberately positioned so that the weight of the deck is applied to areas of the yard that will not be impacted by your septic tank or any other utility lines that are connected to your home. In order to do this, professional assistance is required, and you should exercise prudence when planning and implementing the project.

Patio Alternatives

It is safer to construct a deck over a septic tank than it is to construct a patio, although it is preferable to utilize a patio option. Because of this, the footings of the deck will need to be deliberately positioned such that the weight of the deck is transferred to areas of the yard that will not damage your septic tank or any other utility lines that are linked to your home. While planning and executing on this project, you should seek expert assistance, and you should use prudence at all times.’

Conclusion

Addition of a patio or deck over a septic tank should be avoided unless you have spoken with specialists and have come up with a solution that will not cause damage to the tank and will not cause future difficulties. It is often a good idea to have your property assessed before purchasing it so that you can budget for the costs and complications that may arise while carrying out future renovations.

In North Carolina, there are many distinct types of septic systems in use, but the vast majority of the over 2 million systems in use throughout the state are minor variations of the typical septic system. This system includes a septic tank as well as a drainfield that is filled with gravel (usually two to six trenches). Since the mid- to late-1990s, classic gravel aggregate trenches have been phased out in favor of innovative gravel-less trench designs, which have become increasingly popular.

  • Some of the most often used gravel-free trenches nowadays are either long and narrow, tunnel-shaped chambers in the trenche, or gravel replacements such as expanded polystyrene aggregate.
  • A booklet from the Cooperative Extension Service, AG-439-13, Septic Systems and Their Maintenance, outlines the typical system, easy adjustments to it, and the most significant maintenance requirements.
  • The application of these technologies is now widespread, whether in new housing projects or in the replacement or repair of malfunctioning septic systems in residences and businesses.
  • In order to address this, state regulations provide specified maintenance requirements for a number of these more advanced technology.
  • Furthermore, state regulations mandate that the health department examine these systems on a regular basis.
  • Are you familiar with the location of your septic system and repair area?
  • If you do not have a copy of your septic system permit or a soil evaluation document, contact your local health department.

This Septic System Owner’s Guidefile folder should contain the following items: It is normally possible to establish the location of a septic tank and drainfield by looking at a copy of the permit and consulting with a septic contractor, a consultant, or the local health department A “repair area or replacement area,” in which a second drainfield might be constructed if necessary, has been required on nearly all home sites approved since the early 1980s, according to state law.

It should be noted on your septic system permit that this repair area was designated by the health department when the site was allowed.

Some Important Facts to Understand About Your Septic System

  • Are you using any particular kind of system? North Carolina has several distinct types of septic systems, but the majority of its almost 2 million systems, which are slightly modified versions of traditional septic systems, are found throughout the state. Septic tanks and drainfields with gravel-filled ditches are included in this system (usually two to six trenches). Trenches made of gravel aggregate have mostly been phased out since the mid- to late-1990s, and modern gravel-free trench designs have taken their place. Alternative materials are used in lieu of gravel in some trench designs that do not require it. Some of the most often utilized gravel-free trenches nowadays are either long and narrow, tunnel-shaped chambers in the trenched or gravel replacements such as expanded polystyrene aggregate. Another type of alternative trench material that is being utilized in some regions of the state is big diameter pipe, permeable concrete blocks, and even recycled rubber tires that have been cut into chips or bits of a specified size and shape. Septic Systems and Their Maintenance, published by the Cooperative Extension Service as AG-439-13, outlines the standard system, easy changes to it, and key maintenance requirements. The utilization of systems with pumps, mechanical pretreatment units, and biofilters, among other more advanced forms of on-site systems, has increased significantly in the previous 20 to 25 years. Numerous new housing developments, as well as the replacement or repair of failed septic systems in houses and businesses, are increasingly using these technologies. Septic systems that use these innovative technology demand a greater level of upkeep than conventional septic systems that are more traditional. As a result, a few of these more advanced systems are subject to special maintenance obligations under state law. The hiring of a state-certified operator to examine and maintain the system on a regular basis is frequently required by state sewage regulations. The health department is also required to check these systems on a regular basis, according to state regulations. The sort of system you have and the regulatory requirements for long-term maintenance can be determined by contacting your local health authority. Do you know where your septic system and repair area are located? Knowing where your septic tank (and any additional pretreatment units) and drainfield are located is essential to properly maintaining your septic system. For a copy of your septic system permit as well as a soil evaluation document, contact your local health department. The approximate locations of each of the system’s components, as well as the size of the septic tank, are indicated on these forms. This Septic System Owner’s Guidefile folder should have all of the following items: Septic tank and drainfield locations may generally be identified with the use of an original permit as well as an experienced septic contractor, consultant, or representative from the local health authority. A “repair area or replacement area,” in which a second drainfield might be constructed if necessary, is required on nearly all home projects approved since the early 1980s. It should be noted on your septic system permit that this repair area was designated by the health department when the site was approved. This area must also be protected from excavation, the construction of a home extension, garage, or outbuilding on top of it, the installation of a swimming pool, and any other soil disturbance activities, as stipulated by law. Important Information Regarding Your Septic System

I’m curious in the type of system you have. In North Carolina, several distinct types of septic systems are in use, although the vast majority of the over 2 million systems in operation throughout the state are minor variations of the typical septic system. a septic tank as well as a drainfield with gravel-filled trenches are included in this system (usually two to six trenches). Since the mid- to late-1990s, classic gravel aggregate trenches have been phased out in favor of innovative gravel-less trench designs, which have become more popular.

  1. The most often utilized gravel-free trenches nowadays are either long, narrow, tunnel-shaped chambers in the trenches or gravel replacements such as expanded polystyrene aggregate.
  2. The Cooperative Extension Service document AG-439-13, Septic Systems and Their Maintenance, outlines the typical system, easy adjustments to it, and key maintenance requirements.
  3. These technologies are currently being employed in a large number of new housing developments, as well as to replace or repair failing septic systems in residential and commercial buildings.
  4. As a result, state regulations specify precise maintenance needs for a number of these more complex systems.
  5. Additionally, state regulations mandate that the health department evaluate these systems on a regular basis.
  6. What is the location of your septic system, as well as the repair area?
  7. For a copy of your septic system permit and soil evaluation document, contact your local health authority.
  8. Keep these items in the folder labeled “Septic System Owner’s Guide.” Septic tank and drainfield locations may normally be identified with the help of an original permit as well as assistance from a septic contractor, consultant, or the local health department.
  9. It should be noted on your septic system permit that the health department designated this repair area when the site was approved.

The law also compels you to safeguard this area against activities such as excavation, the construction of a home extension, garage, or outbuilding over it, the installation of a swimming pool, and any other soil disturbance activities. Some Important Facts to Know About Your Septic System

  • What is the age of the system
  • What is the location of the tank and drainfield (they may or may not be on the same property or even on the same parcel of land)
  • When was the last time the tank was pumped
  • What is the frequency with which it has been pushed
  • Is it necessary to clean the “effluent filter” in the septic tank on a regular basis (effluent filters are required for systems established after 1999)
  • Has there been any indication of a likely failure? In what location can I get a copy of the permit and documentation proving how effectively (or poorly) the system has been maintained
  • Do you know whether any improvements have been made to the house that would necessitate expanding the capacity of the system? Is the system still operational, and if so, when and by whom was it repaired?

In what year did it first come into use? If the tank and drainfield are not on the same property, where are they placed (they do not have to be adjacent to one another). When was the last time the tank was emptied; and How often has it been pumped; how long has it been running; Is it necessary to clean the “effluent filter” in the septic tank on a regular basis (effluent filters are required for systems established since 1999); Is it possible that there have been signals of a potential failure?

Is the system still operational, and if yes, when and by whom was the repair completed?

  • What is the system’s age
  • What is the location of the tank and drainfield (they may or may not be on the same property or even on the same lot)
  • When was the last time the tank was pumped? How many times has it been pumped
  • How often has the “effluent filter” in the septic tank been cleaned (effluent filters are necessary for systems established after 1999)
  • Is it possible that there have been signals of a probable failure? In what location can I get a copy of the permit and documentation proving how successfully (or poorly) the system has been maintained? Have any additions been made to the house that would compel the need to increase the size of the system? Is the system still operational, and if so, when and by whom?

Keep waste disposal to sewage alone.

  • It is not acceptable to utilize your septic tank as a garbage can for items such as cigarette butts, tissues, feminine hygiene products, cotton swabs, cat litter, coffee grinds, or disposable diapers. Reduce the amount of time you use your garbage disposal. These contribute a significant amount of additional solids. It is not recommended to throw fat or cooking oil down the drain. You should avoid putting toxic chemicals into your system, such as solvents and oils. You should avoid using paint thinners and paint thinners that have been dumped. You should avoid disinfectants and pesticides. Conserve your funds. Most of the time, commercial septic tank additives are not required.

Ensure that the system is protected against physical harm (site maintenance).

  • Maintain a layer of plants on the soil over the drainfield to prevent soil erosion from occurring. Don’t drive your car above the system’s limits. Try to avoid building over the system or in the repair area. The natural shape of the terrain immediately downslope of the system should be preserved, and this region should be protected against excavation (cutting and filling). Neither asphalt nor concrete should be used to cover the tank or drainfield.

All wastewater should be disposed of in a system that has been authorized.

  • You shouldn’t install a separate pipe to transport washwater to a side ditch or into the woods. This is against the law

The house and the yard (site maintenance)

  • Conserve and preserve the area where your septic tank and drainfield are located
  • Trees that thrive in moist environments should be cut down and removed. Willows, elms, sweetgums, and certain maples are examples of such trees. Surface water should be diverted away from the tank and drainfield by landscaping the yard. Inspect the system to make sure that water from the roof, gutter, and foundation drains does not overflow
  • It is recommended that if your system is located at the base of a slope, you build a french drain to channel subterranean water. Ensure that drainage ditches, subsurface tiles, and drainage outlets are kept in good condition so that water may readily flow from them.
