How Far From Septic Tank Can I Build My Deck? (Question)

It is usually not a good idea to build a deck near or on top of a septic tank. Most zoning ordinances will require that you maintain at least a 5′ setback from an underground septic system.

  • – A full foundation must be 10 feet from the septic tank and 20 feet fromthe leaching area. – A slab foundation such as a garage must be 10 feet from the septic tank and 10 feet from the leaching area. – Concrete columns for a deck must be 5 feet from the leaching area and not disturb the septic system.

Can you build around your septic tank?

It is never recommended to build a structure over any portion of your septic system. No permanent structures should be built over any portion of the system, but at least in this case the homeowner can pump out their septic tank.

What is the minimum safe distance from the septic tank?

At least 15m from the nearest water supply. This is a minimum and should be more if the ground is rocky and fissures could take the outflow further. It should be at least 3m from the nearest building. Avoid areas where rainwater would stand or flow over the tank or vehicles could drive over it.

How close can you build next to a drain field?

– A full foundation must be 10 feet from the septic tank and 20 feet from the leaching area. – A slab foundation such as a garage must be 10 feet from the septic tank and 10 feet from the leaching area. – Concrete columns for a deck must be 5 feet from the leaching area and not disturb the septic system.

Can you build a patio over a leach field?

You can’t build a paver patio on top of a septic tank, and doing so could be against the planning laws of your state or local area. Septic tanks can take very little weight without getting damaged, and you’ll also need access to the tank in the future too. You shouldn’t build a deck on one either.

Can you build a deck over a septic tank?

You should never build a deck over a septic field; doing so will prevent the natural draining and dissipation of the effluent. This can ruin the septic system, not to mention releasing foul smells into the air all around your deck. The dissipating effluent can also rot the deck from underneath.

Can septic tanks collapse?

Septic tanks can collapse for a variety of reasons. This is one of the most serious septic tank problems that can occur. Once a tank is emptied of water, it is much more prone to collapse. That is because the pressure of the surrounding soil is no longer counter-acted by the water inside the tank.

How close to a septic tank can I build a pool?

Installing an inground pool has greater restrictions and will probably need to be installed at least 15 to 25 feet away from the septic tank or leach lines, depending on your county’s code requirements.

Can you put a garden over a septic field?

Planting over a septic leach field (drain field) is possible if it is done with care. If you have limited space on your property where you can garden, the leach field may be the only spot for landscaping. Vegetable gardening over a leach field is not recommended.

How close can leach field be to house?

Local codes and regulations that stipulate the distance of the septic tank from the house vary depending on the locale, but the typical minimum distance is 10 feet.

How far is distribution box from septic tank?

The D-box is normally not very deep, often between 6″ and two feet to the top of the box. You may also see a pattern of parallel depressions, typically about 5 feet apart, that mark the individual drainfield leach lines. The D-box will at or near end of the drainfield area that is closest to the septic tank.

Can you pour concrete over a septic field?

Paving Over Your Septic Tank You should never pave over your septic tank. Although soil compaction is not a major issue for septic tanks, there are other dangers presented by placing an insecure septic tank underneath concrete and heavy vehicles.

Can you put a concrete patio over a septic tank?

You should not build a patio over or near a septic tank. Septic tanks are not built to withstand the weight of a concrete slab or pavers and you risk damaging the tank or the waste lines. You should make sure there is a 5 foot distance between the edge of the septic tank and any heavy materials.

Can you put a concrete slab over a septic tank?

We get a lot of questions from homeowners about whether they can put a patio over their septic tank. While it is theoretically possible for this to work, there are no guarantees that just because you pour a new concrete slab over your septic system that everything will be fine.

Can You Build Deck Over Septic Tank?

It is one of the most exciting and gratifying home remodeling tasks you can undertake to create an outside living space. A finished deck, no matter how complicated or basic, is a wonderful location to spend time with friends and family while also enjoying your house. What might put a kink in your deck-building plans, though, is the question of whether or not you can build a deck on top of a septic tank. Although it is possible to construct a deck over a septic tank, this does not automatically imply that it is a good idea.

Creating a deck over a septic tank requires careful planning and execution.

In this article, you’ll discover the fundamentals of installing decks over septic tanks, as well as the dangers and construction codes related with these projects, allowing you to determine whether or not this is a good idea for your home or not.

Can You Build a Deck Over a Septic Tank?

It is feasible to construct a deck over a septic tank, but it is not necessarily a smart idea. There are a variety of factors that should cause you to stop before deciding to build your deck over a septic tank. Building a deck without disrupting your septic system is a difficult task, and you will need to be resourceful. However, it is not impossible or difficult; it simply takes more preparation and adjustment. Consider it a one-of-a-kind design challenge that will push you to be more creative and strategic in your planning!

Risks of Building Over a Septic Tank

The construction of a deck directly over the tank will make it difficult, if not impossible, to pump out the tank. The tank’s upkeep is extremely vital, and covering the tank with a wood framework makes that task much more difficult to complete. Every three to five years, your septic tank should be drained and emptied, and older tanks may require more frequent maintenance. This makes it unwise to construct a deck over a septic tank unless you are forced to do so by circumstance. It is also critical to preserve the septic lines and drain field in their original condition.

This liquid, which is referred to as effluent, drains out into the drain field and dissipates in the earth and the surrounding air.

When something interferes with the process, however, it becomes readily apparent to the observer.

Building a deck over a septic field is not recommended since it will impede the natural draining and dissipation of the effluent from occurring.

This can cause damage to the septic system, as well as the release of unpleasant odors into the air all around your deck area. The dispersing effluent can also cause the deck to deteriorate from the bottom up. There is nothing more unpleasant than sitting on a deck that smells like a sewer!

Guidelines for Building Decks Over Septic Tanks

Construction of a deck over a septic tank should be avoided wherever possible. If there is absolutely no other option, construct your deck as high as possible to provide yourself and service employees with plenty of space to work. Adding a trap door or hatch onto the deck directly will make pumping and emptying the tank much less of a headache in the long run. When designing your deck, make a note of the precise positions of your septic lines and drain field and mark them off with flags to ensure that you do not construct over them.

If your home is equipped with an old, empty, or decommissioned septic tank that is no longer in service, it is permissible to construct a deck over the tank, lines, and drain field.

Deck Over Septic Tank: Footings and Framing

If you want to build a deck over a septic tank, you should be aware that each deck footing must be at least 5-10 feet away from the septic tank at all times, depending on where you live in the world. However, doing so may result in the footings being too widely apart to allow for the construction of a structurally sound deck that complies with code. Decks that are too widely apart will droop, and they won’t survive more than a few of years if the footings are placed too far apart. If you discover that your deck layout necessitates the placement of footings that are too far apart, you might want to consider framing the deck with steel rather than wood.

How Big Is a Septic Tank?

Septic tanks are available in a variety of sizes depending on the size of the residence; for example, a two-bedroom ranch will have a significantly smaller tank than a six-bedroom country estate. The Environmental Protection Agency advises sizing the septic tank depending on the number of users and the size of the home, as well as the amount of water that will be used. The usual size of a septic tank is between 750 and 1250 gallons in capacity. This is enough to allow the tank to filter and treat a few years’ worth of water and waste before it has to be replaced.

Tanks extend approximately one foot in each direction for every 250 gallons that the capacity required rises.

Septic tanks are generally made of precast concrete, plastic, fiberglass, or steel, with steel being the least popular due to the high cost and corrosion prone nature of steel tanks.

How Deep Are Septic Tanks Buried?

Contrary to popular opinion, septic tanks are not buried particularly deeply in the ground, as is commonly assumed. Septic tanks that are dug too deeply might be cracked or collapsed by soil weight, causing the effluent to leak and soak into the soil around the tank rather than draining into the drainage field. The majority of septic tanks are buried between 4 inches and 4 feet below ground level. This is dependent on the kind of soil, the slope of the yard, the tank design, and a variety of other factors.

To determine the precise placement and depth of the tank and septic lines, which you should do before constructing a deck over them, consult a professional. This will assist you in avoiding the placement of deck footings in areas where they might cause harm.

Rules and Codes Regarding Septic Tanks

Before you begin construction on your deck, you should research the building rules in your area that pertain to septic tanks. Construction of a floating deck over an existing septic tank is permitted in some locations. In others, it is prohibited, and violating the law can result in penalties and the removal of the deck. Septic tanks, drain lines, and drain field must be positioned at least 10 feet away from building slabs, roadways, decks, and other buildings in some jurisdictions, such as Ohio.

You will never be permitted to build over septic lines or drain fields; these regulations are only applicable to construction near tanks.

These requirements apply not just to decks, but also to other types of construction, such as walls and trees, foundations, slabs, and other types of landscaping.

How Close Can a Deck Be to a Septic Tank?

It is recommended that you examine your local building codes for septic tanks before beginning construction on your deck. Construction of a floating deck over an existing septic tank is legal in some areas. In others, it is strictly prohibited, and violating the law can result in fines and the removal of the deck from the property in question. For example, in Ohio, the septic tank, lines, and drain field must be positioned at least 10 feet away from building slabs, roadways, decks, and other buildings to be considered functional.

Septic lines and drain fields are never allowed to be built over; these regulations apply exclusively to construction near tanks.

This set of rules applies not just to decks, but also to other types of building such as walls and trees, as well as foundations, slabs, and other types of landscaping.

Can You Build a Floating Deck Over a Septic Tank?

The construction of floating decks, which are essentially free-standing wooden platforms that are placed at or slightly above grade, should not take place over an existing septic tank. The weight of the deck on the supports might cause the septic system’s ability to properly process and drain waste to become displaced and disrupted. It is possible that you may become the proud owner of the stinkiest floating deck in the city if you ignore this warning. Construction of a hybrid floating deck, which uses underground footings similar to that of a traditional deck while remaining short and distinct from the home, is a straightforward option.

This will create the illusion of a floating deck without putting additional strain on the soil above the septic tank’s ability to sustain weight.

Can You Build a Deck Over a Septic Field?

It is never recommended to construct a deck over a septic field. In order for sewage to flow out into the groundwater or evaporate into the air, septic fields must be built to allow for this. When you disturb the septic field, it causes backup, which causes the ground to become murky with tainted wastewater. The stink and look will be quite visible, and it is possible that the entire septic system will need to be repaired. Even if you are planning to construct on top of an existing septic field, you should properly evaluate the soil to ensure that it is no longer dripping with water.

What Can You Put Over a Septic Tank?

Septic tanks cannot be immediately overtopped except for decks or pergolas that are built on footings more than five feet away from the tank’s inlet and outlet. In addition to septic system components such as concrete slabs, foundations, and shrubs, other constructions can have a negative impact on the system’s health and performance.

Conclusion

It might be difficult to construct a deck over a septic tank. It is feasible, but it is not always a sensible decision. Even if you decide to create the deck, there are a number of considerations to bear in mind. Before you begin construction on a deck over a septic tank, conduct thorough study and planning, and always keep the septic system in mind. Have you ever constructed a structure over a septic tank?

Can You Build a Deck Over a Septic Tank?

Previously, we explained how to construct a deck over a manhole or drain; but, what about constructing the same structure over an onsite septic tank? The ability to provide space for a manhole cover or a drain, or to construct an easily accessible hatch, is one thing; but, what does the code say about building a deck on top of a septic tank? In the event that you have a septic tank in your backyard, you may have a slew of questions running through your head at any given time. Is it possible to construct a deck over a septic tank?

What, if any, threats does it provide, and what should you do if you have no choice but to construct it there?

A deck over your septic tank is not recommended if your tank is in an exposed location.

What Is a Septic Tank?

In the United States, septic tanks and septic systems are wastewater treatment facilities that are typically found in rural settings. It is not unusual to see some subterranean tanks near buildings if there is a lack of available space, although this is not the norm in most situations. These tanks utilize a combination of nature and technology to purify the wastewater that flows through your home’s plumbing system (and, in some cases, throughout the neighborhood). As a result, it is reasonable to presume that these tanks are exceedingly dangerous to people if they are exposed to the gases or water contained within them.

  1. It’s common for these drain-fields to be soil absorption fields.
  2. Solids sink to the bottom of the sea, whereas oily debris floats to the top.
  3. These pipes are buried in leach fields, chambers, or other units that are designed to guarantee that water seeps gently into the soil as it passes through.
  4. Some tanks simply employ the same organic matter that is used as a filter in other tanks (peat, sawdust, or foodstuffs, for example).
  5. It is not commonplace for most states, counties, towns, and localities in the United States and the United Kingdom to restrict the construction of anything over septic system tanks or drain fields, particularly in rural areas.

The Environmental Protection Agency recommends that you check with them before planning to install a deck over an existing septic tank.

Dangers of Building Over a Septic Tank

The risks associated with septic tanks may be separated into two categories: those associated with inadvertently puncturing the tank or its pipes, and those associated with not doing so. Unlike the latter, the former are active threats, whilst the latter are passive threats. In spite of technical advancements, it is critical to remember that septic tanks pose a threat to human health and will most likely continue to do so in the foreseeable future. As a consequence of the sewage gases that have been trapped within the structure, notably carbon monoxide (which is produced as a result of bacteria eating organic materials), it is potentially dangerous to humans.

After 15 to 40 years of use, the average lifespan of a septic tank is reached, at which point the tank begins to degrade.

In addition to endangering human health, this poses a threat to the ecosystem as well.

They have the ability to spread either directly or indirectly.

  • What Kind of Plants and Trees Should Be Avoided

You can enjoy the outdoors in complete comfort when you have a raised deck. If, on the other hand, the greatest location for a deck is directly over the septic field, you might reconsider your intentions for enhancing your property. An effective septic drain field requires exposure to sunlight and air movement to allow liquids to soak through the soil and evaporate into the atmosphere. In addition to interfering with the two tasks, a deck has the potential to reduce the lifespan of the septic system and drain field.

Tip

For a septic field to work correctly, it requires air movement and sunlight. A deck interferes with both, making that particular location an unsuitable location for a deck or any other construction. Septic systems are a type of sewage treatment and disposal system that is commonly seen in rural and semi-rural settings. It is necessary to transport all of the liquids and waste from the home into a tank. The solids sink to the bottom of the container and liquids disseminate into an aleach field, which is also known as a drain field or aleach field.

After flowing from the septic tank into the drain field, liquids slowly soak into the soil and evaporate into the air as they pass through the system.

Structures and Septic Fields

It is not advisable to build a deck or other building on top of a drain field. A deck provides protection from the sun and restricts air movement. Even if the supports are set with care between the leach lines, you run the chance of destroying the field, which is an expensive error that affects the entire household while the system is being fixed or replaced. An additional disadvantage of a deck is that it limits access to the septic system, which includes the concrete or polyethylene tank, which should be examined every three years and emptied every three to five years.

Because of the additional dirt in a raised bed and the base of a shed, a substantial amount of weight is added to the field, which can cause the pipes to get damaged and interfere with evaporation from the ground.

Plants Appropriate for Septic Fields

While constructing a deck or other structures to the property is not permitted due to the septic field’s design, creating a wildflower meadow or lawn is. Shallow-rooted grasses and flowers absorb moisture and nutrients from the leach lines, increasing the ability of the system to distribute the wastewater into the environment and reduce the amount of time it takes. Wildflowers such as native grasses and clover that attract butterflies and hummingbirds, as well as poppies and salvias, as well as a range of other flowers that attract butterflies and hummingbirds, improve the scenery while preventing human activity over the septic field.

Planting deeper-rooted plants, shrubs, and certain trees along the perimeter of the septic field is permissible as long as they are kept at least 10 feet away from the drainfield lines.

A root barrier should be installed to prevent root incursion, which can cause clogging and damage to the pipelines. Make use of smaller shrubs and trees, such as crepe myrtles, blooming cherries, and dogwoods, and place them at a distance that is equal to or more than their maturity height.

Plants and Trees to Avoid

Planting water-loving plants in close proximity to septic fields is discouraged. While the roots of most trees spread out to around twice the width of the canopy, the roots of willow trees seek find water to the extent that they spread out three to four times the average root spread of other species. Beech, elm, and red maple trees are among the other species that should not be planted near a septic system, according to the EPA. Planting a vegetable garden above drain lines is not recommended, even if the field is the sole sunny location in the environment.

Furthermore, avoid growing bulbs in the drain field, since this will need the digging of holes in the overlying soil.

Can I Build a Patio or Deck Near a Septic Tank?

Is it permissible to construct a patio or deck near a septic tank? tybeedreaming inquires, My septic tank is located around 15 feet from the back of my house. I’d want to build a patio or perhaps a deck out on the back deck. With regards to dealing with a septic tank, which would be preferable?

Our Answer

A building atop an active septic tank is not recommended since the tank must ultimately be opened in order to be pumped at some point. Second, if the field were to ever collapse – which it is certain that it would – the entire area would have to be dug up and rebuilt. Whatever route you choose, you must ensure that access to the tank is provided, and you must be aware that you may be required to replace the field entirely – which would presumably entail replacing a patio or deck that has been built on or near it, which you most likely do not want to do in the first place.

If the septic system is no longer in use, the tank must be properly abandoned so that nothing may collapse in it.

r/HomeImprovement – Building a Deck Near Septic System

Hello and welcome to everyone. I’d want to have a deck built onto my house, and I’m now working with a contractor to make that happen. I’ve run into a problem with the position of the deck and wanted to hear what everyone’s thoughts were on the matter. First and foremost, here is a floor plan of my home for your consideration. The risers of the septic tank are shown by the circles towards the top of the first illustration. The red lines in the first image are also doors, as can be seen. While the bottoms of both doors are approximately 4 feet above ground level, the right side door now has cement stairs going out to the parking lot, but the other door does not have stairs, thus the door is simply sort of floating there, heading nowhere.

A call was made by our contractor to the department of health for our county (in Ohio) to find out what the rule was for setback distances from septic tanks, and he was informed that all constructions must be at least 10 feet away from septic tanks.

I had a few questions I wanted to ask on this forum:

  1. I may submit an application for a deviation to the code to see if I can construct a structure closer to the tank. I was under the impression that we would only need to come out about 5 feet from the rear of the house, which would leave us with a 6 foot setback from the tank. When it comes to granting a variance, how probable is it that the county will do so? In fact, is it even wise to build that near to the sewer line? If I can’t construct the deck on the right side owing to the septic tank, can I still construct the deck on the left side of the house? Do you think there is a problem with the deck being built on top of the waste line that runs from the home to the tank? Are there any other possibilities that I am not aware of? Is there anybody else in Ohio who has dealt with the issue of building a deck near a septic tank? If yes, please describe what you did.

To test whether I can construct closer to the tank, I can apply for a variance to the code. Our plan was to come out maybe 5′ from the rear side of the house, which would leave a 6′ setback from the tank, which I thought would be plenty space. When it comes to granting a variance, how probable is it that the county would do so? In fact, is it even wise to build that near to the sewer line? If I can’t construct the deck on the right side owing to the septic tank, can I still construct the deck out back?

Do you think there are any other choices that I am missing?

Has anybody else had to deal with this problem?

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.

We can assist you with any of your wastewater system needs, and our specialists can also assist you with your septic installation and maintenance requirements: 210.698.2000 (San Antonio) or 830.249.4000 (Austin) (Boerne).

How Remodeling Can Affect Your Septic System

Building near a septic tank and drain field may have a negative impact on the performance of any septic system, and it is easy to ignore this while upgrading a property. This is also true for people who are considering purchasing a property and intend to remodel it. It is preferable if you are aware of the exact location of your tank and drain field. This will prevent new construction projects from interfering with the normal maintenance of your system or causing damage to your septic tank. Before beginning on any big job that may include your septic system, make sure you have a solid understanding of septic systems under your belt.

It is an excellent resource that can help you feel much more confident about owning, maintaining, and renovating in close proximity to a septic system.

Building Near aSeptic Tank

What may possibly happen if you fail to locate your system? It is possible that your septic tank is in the route of a huge construction truck. It would be the least of your worries if your septic tank lid were to break. Cracks in the septic tank may be caused by the weight of building equipment on the site. It is possible that these will not be apparent soon after the event. Cracks will grow with time, however, and will pose a major structural threat over time. In most cases, a tank is clearly marked in some way to make it easier to locate.

  • This will guarantee that the driver is aware of the exact location of the tank and that the tank has enough space to move about.
  • In addition to causing damage to your tank, construction may prevent a pumper from entering the tank.
  • This not only makes it difficult to locate the tank, but it also makes it difficult, if not impossible, to maintain it.
  • If you have a deck or patio that prevents access to the tank, you may be forced to demolish the building, squandering the money you invested on its construction.

Building Near aDrain Field(Leach Field)

If a drainage field is destroyed, the expense of replacing it might be significantly higher. The most serious problem that might occur from building near a drain field is the damage that heavy construction equipment can inflict to the drain field. The weight of a large number of heavy trucks moving over a drain field will shatter the pipes in the drain field and compress the soils beneath the trucks. Compacted dirt in a drain field will impair the ability of the drain field to drain effectively.

Without any air pockets to fill, the effluent will be pushed to rise towards the surface of the soil, where it will eventually pour out onto the ground.

It is preferable to keep any new structures away from the drain field if as all possible. A few instances of how construction near a drain field might potentially result in a problem are shown below.

Problems Building Near a Drain Field

  • Building an in-ground pool would almost certainly need a permit, but it is critical that it be located away from your drainfield. The most obvious issue would be if you were to cut into your drainage system. However, even approaching too close might cause soil compaction in the surrounding area, reducing the life expectancy of the drain field. An above-ground pool adds a significant amount of weight to the earth. It is common to see sheds built on top of leach fields because the water that drains out will soak down into the drainfield and add a significant amount of water. While it is possible that the weight of the shed could cause some soils to contract, it is also likely that traffic from machines would increase. Larger sheds and pole barns should be maintained away from drainfields at all costs. They are unquestionably large and heavy enough to cause issues. They are also large enough to accommodate heavy vehicles, which will further exacerbate the situation. Some individuals choose to build gardens on top of the drain field to beautify the area. Make certain that you are not growing anything with roots that are large enough to penetrate the pipes. In most cases, there is a two-foot layer of dirt cover, but this might vary. When in doubt, it’s advisable to be careful and move the garden to a different location. Fence posts are commonly found in and around gardens. Make certain that the posts are not too large that they are digging into the drain field stone (aggregate). It is possible that huge posts or poles that are buried too deeply will pose an issue. Decks, flagpoles, and huge fences are examples of structures that might cause this. When a septic tank is replaced, it is possible that a leach field will be harmed. The big trucks required to transport the concrete septic tank will have a negative impact on the soils. A plastic septic tank is an excellent solution for completely avoiding the problem. Because they are small and lightweight, they can be carried by hand.

Having established the dangers associated with developing near your septic system, we can go on to discussing ways to avoid any difficulties from arising in the future. The most effective technique of preventive is to be aware of the locations of each component of your system.

How to Locate Your Septic System

Keeping track of where your system is at all times might be a challenge. A large number of consumers only get a glimpse of the entire system during the house purchasing inspection process. In the event that you still have access to your report, it may contain information on the system’s location, as well as a 2-D drawing of the system’s layout. We will provide photographs with our report in order to provide a more accurate reference for the location of the system components. The option to have someone come out and find your system is always available if you have misplaced your report.

Building near a septic tank and drain field can be hazardous, so exercise caution and use common sense while constructing any structure in the vicinity.

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.

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.

When necessary, slopes should be added, and these areas should be thoroughly evaluated before proceeding with the rest of the project.

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.

Rules and Codes Regarding Septic Tanks

Construction around or on top of your septic tank should be done in accordance with local building codes, which should be checked before you begin work. The construction of a floating deck on top of a septic tank is permitted in some places. The practice is unlawful in some jurisdictions and can result in penalties and the removal of the deck. Depending on where you live, you may be required to have your septic tank, pipes, and drain field installed at least 10 feet away from building slabs, roadways, decks, and other buildings in Ohio.

These regulations apply not just to decks, but also to other forms of construction such as walls and trees, foundations, slabs, and other sorts of landscaping. If you live in an area where these limitations apply, avoid constructing structures close or over the tank, lines, or drainage field.

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:

Object Yes No
Patio No
Deck No
Pavers No
Gravel No
Plants Yes
Tarp Yes
Trees No
Flowers Yes
Driveways No
Grass Yes

Was wondering what you could put over a septic tank.

Can You Put A Paver Patio Over A Septic Tank? (Must Read!)

Consider the following scenario: you’ve found the ideal location in your yard for your new patio, but there’s a septic tank in the way. What do you do? Can you just go ahead and build the patio on top of the existing structure? You are not permitted to construct a paver patio on top of a septic tank, and doing so may be in violation of the planning regulations of your state or local jurisdiction. Septic tanks are capable of withstanding just a small amount of weight without becoming damaged, and you will want access to the tank in the future.

With the help of this article, you will be better prepared to comply with local planning requirements when it comes to constructing a patio on or near your septic tank.

Should I Ever Pave Over My Septic Tank?

The practice of constructing a structure over a septic tank is not advised, and in fact, some counties may have rules against it. If you are aware of the location of your septic tank, you will need to plan your patio around it. What is the reason behind this? First and foremost, why make life difficult for yourself? This means you must have access to your septic tank, and ideally without the need to lift concrete slabs. Sometimes you’ll notice paved sections over tanks with an access hatch in between the pavers.

  1. This will, without a doubt, help to alleviate the accessibility issue, but it is still far from perfect.
  2. Immediately after, we’ll go through the various sorts of tanks and their weight-bearing capabilities.
  3. Discovering the location of your tank before beginning any construction is the moral of this story.
  4. In this instance, you’ll need to determine whether or not the previous tank was properly refilled.
  5. If you believe that you may have an old tank on your property, consult with a professional surveyor or engineer for confirmation.
  6. This is the million-dollar question.

In order to drain it, you’d have to relocate all of your beautiful furniture and potted plants, and you’d have to prepare yourself for the scent to remain for many days thereafter. It’s hardly the most attractive area in the yard.

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

When it comes to an old-fashioned steel septic tank, the answer is usually “very little.” Modern septic tanks are often constructed of concrete, which makes them much more durable. Some have a “traffic rating” and axle weights, whereas others do not. But the majority of the advise is to avoid parking on or even driving across a septic tank at all costs. A collapse or partial collapse can result in a devastating accident, with the driver, the car, the tank, and the surrounding property all suffering severely as a result of the incident.

  1. If you are installing a new one, make sure to choose a durable concrete tank that satisfies all of the specifications.
  2. The drain field (also known as a leach field) is the region where the drain lines that flow from the tank are located, and you don’t want these lines to be damaged as much as possible.
  3. Make sure that spot is clearly marked so that no one attempts to park there.
  4. Then we’ll look at what you can do to protect the area around your septic tank.

What Can You Put Over a Septic Tank? (Can You Cover Them At All?)

So, what are your plans for this parcel of property that has been delineated? Keep the hatch open to allow for easy access (you can always put a lightweight plant pot over it). Over the cover, we’ve also heard of light sculptures and bird feeders being used (these are also a good way to remind people not to park cars or mowers directly over the tank). You could even make a highlight of the hatch itself by decorating it with mosaic tiles or painting a pattern on it. There’s an unexpected amount of information on this on Pinterest!

  • Plant grass over the drain field since it helps to keep the soil around the septic tank in good condition.
  • Solid waste is separated from liquid waste in the septic tank, which allows it to function properly.
  • The bacteria are more efficient in soil that is loose and well-drained.
  • As much since possible, choose a native grass that will thrive in your zone without the use of fertilizers, as you want to leave the soil as natural as possible.
  • In our most recent post, you may learn more about the many species of natural grass.
  • Trees should not be planted anywhere near a septic tank system.
  • It should go without saying that a septic tank drain field is not a good location for a vegetable or herb garden to be established.

It appears to be a fine concept; but, it would be quite difficult to create a deck that is still load-bearing despite the presence of a vast unsupported region above the storage tank. In addition, we’ve heard that the effluent air can cause harm to wood structures.

How Deep Should Septic Lines Be Buried?

Every drain field is unique due to the variations in soil and water table found in different parts of the country. If you’re building new septic lines, consult with a professional first (and as much as we love a DIY yard project, the whole septic tank thing is best handled by the professionals). The overall norm appears to be at least six inches deep, according to the evidence. This appears to be a shallow depth to us, and according to our study, the optimal depth is between 18 and 36 inches below the surface of the water.

Where Should Your Septic Tank Be Located?

The requirements for septic tank placement differ from one location to the next, but the general guideline appears to be that the tank should be at least 10 feet away from your residence. According to what we’ve previously discussed, you’ll want to choose a location that won’t impede with your driveway or parking because a car of that weight shouldn’t be able to pass over the tank. Additionally, you will require an area for the septic tank’s drain field and lines, which you will not want to plant anything on or build on in the future.

Again, consult with an experienced drainage engineer who can assist you in determining the ideal location for the tank and drain lines.

Conclusion

The bottom line is that because septic tanks are not load bearing structures, you cannot construct a patio or deck on top of them. Aside from that, you’ll require constant access, which is another reason why this is a bad idea. Because it may be against state and local planning laws to construct a paver patio over your tank, the last thing you want is to find yourself in trouble with the authorities – or literally in trouble if your patio furniture falls through and into the tank!
