Where is the distribution box in a septic system?
If your layout consists of a rectangular and level drain site, your distribution box is likely to be located near the edge of the drain field, closest to the septic tank. You can also look for a depression in the ground between the septic tank and drain field a couple of feet in diameter.
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 to septic tank can you build?
– 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.
Can you pump septic from distribution box?
Your distribution box does not need to be pumped as your septic tank does. The distribution box will be down from the septic tank, close to the leach or drain field.
How deep should a distribution box be?
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.
Should a distribution box be full of water?
A septic system distribution box should not be full of water. As effluent water leaves the septic tank towards the drain field, it first enters the distribution box. If the distribution box is full, there is a problem with clogged leach lines or a failing drain field.
How far down is a leach field?
A typical drainfield trench is 18 to 30 inches in depth, with a maximum soil cover over the disposal field of 36 inches.
How deep should a septic tank be?
Septic tanks are typically rectangular in shape and measure approximately 5 feet by 8 feet. In most cases, septic tank components including the lid, are buried between 4 inches and 4 feet underground.
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.
Does a septic tank always have water in it?
A septic tank should always be “filled” to its normal liquid level, or the bottom of the outlet pipe which carries effluent to the absorption area. This normal liquid level is usually between 8” to 12” from the top of the tank on average (see picture at right).
Can you have a dishwasher if you have a septic tank?
DON’T. use your dishwasher, shower, washing machine and toilet at the same time. All the extra water will really strain your septic system. put items down your sink or toilet that can easily be thrown into the trash.
Are dishwashers good for septic systems?
The dishwasher is not affecting the septic tank itself as long as you are using normal quantities of dishwasher detergent. IF choosing between two otherwise equal dishwashers, if you choose one that uses less water that further helps your drainfield.
How far is D box from septic tank?
Depending on its size, the distributionbox will be sunk between 2 and 4 feet below the surface. The distribution box will be buried between two and four feet below the surface of the ground. In the same vein, how can I replace my septic D-box? Line up the septic tank pipes with the distribution box, and then slide the box back toward them until they are completely enclosed within the box. Adjust the distribution box so that both sets of pipe are evenly distributed within the box. Once you are pleased, use plumber’s putty to seal the area around each of the pipes where they come into the box.
A Septic D – Box is defined as follows: An asepticdistributionboxis a container that is used to collect septic system effluent from an aseptic tank and to re-distribute the effluent into a network of associated drain-field or soakaway bed absorption trenches and pipelines.
The distribution box is located in the area between the septic tank and the drain field.
This package typically costs between $40 and $80.

When it comes to aseptic distribution boxes, they are used to collect and transport septic system effluent from an aseptic tank into a network of drain-fields or soakaway bed absorption trenches and pipelines that are connected to the aseptic tank. Are all septic systems equipped with a distribution box, as well? Boxes for distribution: Most, but not all, systems are equipped with a d- box. As soon as the effluent has been separated in the septic tank, it is dispensed into the leach field through the distribution box, which is placed in the leach field.
The distribution box is located in the area between the septic tank and the drain field.
This package typically costs between $40 and $80.
Is it necessary to have water in the septic distribution box? Except for water, you should have nothing in your lines or dropboxes. If a line is becoming saturated, there may be a half-full box of water that is either standing or flowing slowly in the background.

Receive articles, stories, and videos about Distribution sent directly to your email! Now is the time to sign up. Distribution+ Receive Notifications Septic wastewater is delivered to the soil treatment area by gravity in two basic ways: through the distribution box and through the drop box (see illustration). Generally speaking, distribution boxes are employed in subsurface bed systems as well as in a succession of trenches on flat terrain. Parallel distribution is the term used to describe this sort of distribution.
Basic definitions
Distribution boxes are built with an intake at the highest level and several exits at a single lower elevation, as shown in the illustration. It is theoretically possible that the box will then distribute the effluent evenly amongst the trenches. As a result, most state and municipal rules require that every trench supplied by a distribution box be the same length as the preceding trench. Equitable distribution is extremely unusual, if ever, to occur in the real world. Usually, one of the exits is somewhat lower than the others, or organic material development in the box or the pipe causes the flow to concentrate in a single trench, as seen in the illustration.
Distribution boxes should thus only be used on level sites or in bed systems that have been created on a level surface.
The trench outlet pipes are positioned at the bottom of the box, towards the bottom of the box.
When the effluent flows via a supply pipe that is laid with at least a one-inch drop to the next box in the sequence, it is considered to be clean. It then flows into the next trench, and the procedure is repeated until all trenches have been exhausted.
Keeping it level
Typically, distribution boxes are built with an intake at the greatest height possible and many exits at a lower level. The box, in principle, will then divide the effluent evenly across the trenches, as shown in the illustration. As a result, most state and municipal rules require that every trench supplied by a distribution box be the same length as the previous trenches. Equitable distribution is rare, if not impossible, to achieve in practice. Usually, one of the outputs is somewhat lower than the others, or organic material development in the box or pipe causes the flow to concentrate in a single trench, as seen in the illustration.
Distribution boxes should only be used on level sites or in bed systems that have been erected on a level surface to prevent this from happening again.
The trench outlet pipes are positioned at the bottom of the box, near the bottom edge.
In this way, the effluent can flow via a supply pipe that has been placed such that there is at least a one-inch drop to the next box in the series of boxes.
Regulating flow
There are a variety of flow-control mechanisms that may be fitted in each type of box to allow the flow to be adjusted to the specific trenches. Those responsible for system administration and biomat production are referred to as “supervisors.” They are not designed to make up for improper installation techniques! There are also several patented items on the market that employ the notion of a “tipping bucket” to dose and rest the gravity trenches, which are available for purchase. When using these technologies, both you and the homeowner must know that they require a greater degree of maintenance and care than is currently available.
An additional effective installation technique that enables for easy inspection and administration of the system is to run solid pipe from the box to the surface of the ground.
Poor practice includes the use of earthen dams and pipe layouts to carry wastewater between trenches without the use of a drop box, which is an example of terrible practice.
We have also discovered that at each stepdown or crossing point, there is a region where effluent is likely to re-enter the atmosphere.
As a result, you’ll have a sequence of puddles in your garden if you do it this manner. This next month, we’ll take a look at the right methods for constructing trenches and beds for gravity distribution.

When your septic tank is operating well, it is out of sight and out of mind, and you may not be aware of all of the subterranean components, such as the distribution box, until something goes wrong. One of the numerous septic tank inquiries that many homeowners have is where the various pieces are located. The ability to understand what this little but critical component performs, where to find it, and what sort of care it required can assist you in keeping your septic tank in good working order.
What Is a Distribution Box?
Distribution box is a tiny box that is installed after the septic tank but before the drain field to distribute wastewater. In most cases, they are composed of either polymer plastic or concrete, and they have many apertures on various sides where the drain field lines are connected to the box. As an example, consider it to be a connection point for the lines that go throughout the leach field. The actual size and style of your system will be determined by your system. In order to ensure that the effluent from the septic tank is distributed uniformly over the drain field, it has been designed to do the following: In order to take advantage of gravity, the distribution box is often placed slightly downhill from the septic tank.
- In addition, the box is often equipped with spinning components that aid in the distribution of consistent volumes of wastewater in different sections of the leach field.
- The wastewater might gather in an uneven manner if this is not done, with some portions of the leach field receiving all of the wastewater and other regions receiving none.
- Regular inspections of the distribution box as part of normal septic tank maintenance can help to verify that everything is going well.
- You may also inspect the distribution box for damage and assess whether it is necessary to replace it.
- Things such as driving over the box, tree roots growing into it, heavy sludge accumulation, and other damage to the box might compel you to replace it sooner than you would have otherwise thought necessary.
- Due to its role in moving effluent from the septic system’s tank to the septic drain field, it seems logical that the box should be installed between them.
- Distribution boxes are typically just 6 inches to 2 feet deep, depending on the manufacturer.
- Site plans or a drawing of the authorized system design should still be available if you have them, and the distribution box should be clearly noted on them.
- Be aware that some smaller systems may not have distribution boxes, while most systems do have distribution boxes.
- It is possible to notice parallel depressions that represent the leach lines and can direct you to the distribution box in rare occasions.
By running a plumbing snake from the septic tank outlet to where it stops, which should be the distribution box, you may get a general estimate of how far it is to the distribution box.
Pieces of a Septic System
The Septic Tank is the tank that collects and stores all of the waste that is generated by the house. Anything that you flush down the toilet or down the drain gets to this location first. This is a photograph of a fresh new 1000-gallon tank being set up.
| The inlet side with the cover open | A new Septic tank in the ground just after setting |
The Riser-A riser is not required in every system; however, when the septic tank is sunk deeper than a couple of inches in the earth, a riser is required. It makes discovering and cleaning out the tank much easier because you don’t have to search around for the tank as you would otherwise. At Superior Sanitation, we have gone over to using plastic risers instead of concrete ones. If you have a riser, it might be built of concrete or plastic. They are stackable and screw together to provide you with greater versatility when it comes to septic tank depth.

The d box, also known as the distribution box, is responsible for separating the flow of waste water to the several lateral drainfield lines. When installed between the septic tank and the drainfield lines, it is called a septic tank separator. The d box on the left has not yet been erected; it is now resting on top of a septic tank on the property line. More than forty years have passed since the d box on the right was planted. Septic Tank to D Box Connection-This is often a short stretch of solid waste line that connects the septic tank to the d box in order for effluent to be able to flow out of the outlet side of the septic tank and into the d box.
- Don’t be concerned if your system takes a lengthy time to transfer data between the two boxes.
- The example provided below has been effective for more than forty years.
- If you are replacing your old tank with a new one and the pipe connecting the two is Orangeburg, it is typically a good idea to replace the line that runs between the tank and the d box.
- This sort of pipe often breaks over time by gradually compressing into an egg shape, which restricts the flow of effluent through the pipe.
- This is where the water ends up, where it will be naturally purified and evaporated by the elements.

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.
It’s possible that a small number of homes will be sharing a bigger communal septic system that will function in a similar manner as a single-family system.
SEPTIC TANK
The wastewater is collected in the septic tank once it has been discharged from the residence. Septic tanks are normally between 1,000 and 2,000 gallons in capacity and are composed of concrete, strong plastic, or metal, depending on the model. Highly durable concrete tanks, which should endure for 40 years or more provided they are not damaged, are the most common. Many contemporary tanks are designed with two chambers in order to maximize efficiency. Household wastewater is collected in the septic tank, where it is separated and begins to degrade before being discharged into the leach field.
- In the tank, oil and grease float to the top of the tank, where they are known as scum, while solid waste falls to the bottom, where they are known as sludge.
- Bacteria and other microorganisms feed on the sediments at the bottom of the tank, causing them to decompose in an anaerobic (without oxygen) process that begins at the bottom of the tank.
- Solids and grease must be pushed out of the system on a regular basis in order for it to continue to function effectively.
- Each gallon added to the tank results in one gallon being discharged to the leach field, leach pit, or other similar treatment facility.
Leach Field
When used properly, a leach field (also known as a “drain field”) is a series of perforated pipes that are typically buried in gravel trenches 18 to 36 inches below grade — deep enough to avoid freezing, but close enough to the surface that air can reach the bacteria that further purify the effluent (see illustration below). As little as 6 inches might separate you from the ground surface, depending on your soil type and municipal regulations. It is customary to cover the perforated pipes with approximately two inches of gravel and a layer of topsoil that is 18 to 24 inches in depth.
- Grass is often sown above the ground.
- The leach field is comprised of rows of perforated pipes in gravel trenches that are used to spread wastewater over a vast area in order to further purify it.
- A bacteria-rich slime mat forms where the gravel meets the soil, and it is responsible for the majority of the water purification work.
- Despite the fact that wastewater freezes at a far lower temperature than pure water, freezing is still a hazard in cold areas.
- The leftover pathogens are converted into essential plant nutrients by these organisms, while sand, gravel, and soil filter out any solids that remain.
- If the system is operating effectively, the filtered wastewater will return to the aquifer as naturally clean water that is suitable for human consumption at this stage.
- Alternative systems may be permitted in situations when traditional leach fields are unable to function properly owing to poor soil conditions or a high water table.
These systems sometimes cost twice or three times as much as a regular system and require significantly more upkeep. 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.
- 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. This will assist you in keeping the load controlled and will also help to extend the life of your system. 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.
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.

What is a Septic Distribution Box?
Riverside, California 92504-17333 Van Buren Boulevard Call us right now at (951) 780-5922. The bulk of your septic system is buried beneath the surface of the earth. The fact that it is out of sight means that many homeowners are not concerned with their garbage collection. However, whether you are planning a septic installation for new construction or feel that there is a problem with the drainage on your property, you should get familiar with the features of your existing system.
What Is a Septic Distribution Box?
The distribution box (or D-box) of a septic tank is a container (usually made of concrete) that absorbs septic tank effluent and re-distributes it into the network of drain fields and pipes that are connected to the tank. To put it another way, its function is to ensure that wastewater is distributed uniformly into the leach field.
How Does it Work?
The distribution box of a septic tank system is responsible for distributing wastewater from the septic system to the dispersion field in an even and consistent manner. When used in conjunction with other pipes, the D-Box links the septic tank as well as absorption devices, such as the drain field leach lines, to the drain field. The distribution box, like the majority of your septic system, is powered by gravity. It is known that liquid waste enters the box through a single pipe and is split equally in order to escape the box through the drain system.
In addition, the box features many holes that are equipped with spinning devices.
This function is essential for a properly functioning and dependable septic system.
This can cause the region to become overburdened, reducing the overall efficiency of the field.
How Do I Find My Septic Tank Distribution Box?
- The position of the distribution box is mostly determined by the amount of space available and the configuration of the septic system’s drain field. Your distribution box is most likely to be positioned near the border of the drain field, closest to where the septic tank is located if your layout is comprised of a rectangular and level drain site
- Otherwise, your layout is not likely to be comprised of a rectangular and level drain site. A couple of feet in diameter dip in the earth between the septic tank and drain field can also be found
- This is another option.
This is mostly determined by the available area and configuration of the septic system’s drain field; however, there are some considerations as well. Your distribution box is most likely to be positioned near the border of the drain field, closer to where the septic tank is located if your plan includes a rectangular and level drain site. You may also search for a dip in the ground between the septic tank and the drain field that is a couple of feet in diameter.
- Outlet Apertures– The majority of well-designed systems will enable the outlet openings to be altered in order to regulate the flow if it is necessary. If a D-box has tilted or tipped, this might result in distribution to just one area of leach fields, which could result in overflow of effluent to the surface, or a backup of effluent into the system or a blockage. Inside– Issues with your system (past or current) might be indicated by the interior of your distribution box, such as flood lines.
COMMON DISTRIBUTION BOX PROBLEMS
Take note if you see flooding in a particular section of your drainfield. It’s possible that your distribution box has been damaged or obstructed, and it will need to be fixed or replaced. This can occur for a variety of causes, including the following:
- Natural wear and tear
- Sludge accumulation
- Improper septic system maintenance
- Invading tree roots
- Driving heavy machinery over the box
- Flooding and other severe weather conditions
- And other factors
It is also possible for the pipes running to or from the box to get blocked or broken.
Additionally, the spinning devices that are attached to the holes may malfunction, resulting in an unequal distribution of liquid.
How Can You Keep Your Distribution Box Functioning?
A correctly installed distribution box is critical to the proper operation of the device. It should be totally flat and no more than a foot below the surface of the earth in any direction. In addition, the system should be installed in accordance with the septic tank’s manufacture standards, whether those specifications call for a fiberglass, plastic, or concrete connection box. Pumping and inspecting your septic system on a regular basis might help your distribution box work effectively. Licensed professionals may inspect the box to make sure wastewater is being distributed appropriately throughout the drainage system.
If you address distribution box concerns as soon as possible, you may be able to protect your home and septic system from damage such as floods.

The Drainfield
The drainfield is a network of perforated pipes (or “laterals”) laid in gravel-filled trenches or beds. After solids settle in the septic tank, the liquidwastewater (oreffluent) is discharged, either by gravity or pressure,to an absorption field, also known as a drainfield or leachfield (seediagram of septic system/drainfield layout).NOTE:In most gravity systems the wastewater first flows into a distribution box (d-box) or tee, which then disbursesthe effluent equally among the trenches in the drainfield, which is where the final treatment takes place.Effluent trickles out of the pipes, through the gravel layer, and into the soil where further treatment occurs.
Thesoil filters the wastewater as it passes (or “percolates) through the pore spaces and the soil microbes treat itbefore it eventually enters the groundwater.
The size and type of drainfield depends on the estimated daily wastewater flow and local soil conditions.
The Soil
The soil under the drainfield is responsible for the ultimate treatment and disposal of the septic tank effluent once it has been treated. Upon entering the soil, organisms in the soil purify and decontaminate the effluent before it percolates downhill and outward, eventually entering groundwater or surface water.
This is because different types of soil have different capacities for treating wastewater. For example, clay soils may be too tight to allow much wastewater to pass through, whereas gravelly soils may be too coarse to give much treatment.
Replacement (Reserve) Area
Every new residence or business that will be served by a septic system must have a specified replacement or reserve space set aside for it. This is a specified area appropriate for the installation of a new drainfield, and it must be handled in the same manner as your current drainfield. A reserve area should have been declared as part of the permission procedure for any sewage system that was constructed after 1980. By the time your septic system has failed, it is too late to correct the situation by pumping your tank.
This is why it is critical to understand where the replacement area is located and how to preserve it (for more information on replacement area care, see “Drainfield Do’s and Don’ts”).
Do These Things
- Find out where your drainfield and replacement area are before you start. It is much easier to safeguard anything when you know where it is located. Locate Your Drainfield. Heavy machinery should be kept away from your drainfield. There should be no parking or driving over the drainfield by cars or heavy equipment
- This might cause cracks in the pipes. If the area is accessible to automobiles, cattle, or heavy equipment, put up a barrier. Reduce your water consumption to a bare minimum. Drainfields are not capable of carrying an endless amount of water. It is impossible for the system to drain and filter effluent when there is more water than it can absorb. This results in the effluent reaching groundwater. Water should be diverted away from the drainfield. Roof runoff and drainage ditches can saturate the soil, causing it to become waterlogged. It is most effective for drainfields to operate when the soil underneath the drainfield is not waterlogged. Maintain a minimum distance of 30 feet between trees and bushes and the drainfield. Please keep in mind that some soil conditions may dictate that plants be placed at an even greater distance from the drainfield.) Drainfields are a common habitat for trees and plants because their large root systems are attracted to and develop in moist places. Drain pipes might get blocked and damaged as a result of this. Landscape Your Drainfield. Over the drainfield, only grass or shallow-rooted plants should be planted. This will prevent soil erosion from occurring. Protect the area where your replacement will be installed. It is possible that this is the only spot with appropriate soil conditions in the event that you need to rebuild, repair, or expand the drainfield. All of the solutions made above are applicable to the replacement area as well
Don’t Do These Things
- Don’t construct anything on top of your drainfield. Patios, carports, and other constructions are included in this category. It is possible that you will cause harm to the drainfield. Do not construct a road over the drainfield. Drainfields require air in order to operate correctly. Biological breakdown and treatment of sewage need the use of oxygen. Make sure you don’t dig up your drainfield. It is possible that the pipes will be damaged
- Large animals and livestock should be kept away from the drainfield. Soil compaction hinders oxygen from getting into the soil and water from moving away from the drainfield
- It also causes erosion. It is not permissible to apply landscaping plastic over the drainfield. Air is required for the drainfield to work properly
- Otherwise, it would fail. Planting a food garden over a drainfield is not recommended. As a result, there is the chance of food contamination. Installing an irrigation system in the drainfield is not recommended. Additionally, the irrigation system should not drain toward the drainfield.
Please call a trained septic specialist for additional evaluation if you detect any of the following indicators of a potential failure or if you have any reason to believe your system is experiencing issues. Please contact Thurston County EnvironmentalHealth at 360-867-2673 if your septic system should fail.
- Odors, surface sewage, or damp areas in the drainfield region are all signs of a problem. Backups from the plumbing or septic tank (which are often a dark liquid with a foul odor)
- Fixtures that take a long time to drain
- The plumbing system is making gurgling sounds. Your drainfield may be failing if you have a well and tests reveal the presence of coliform (bacteria) or nitrates in the water from it. Even in dry weather, there will be a pool of liquid over the drainfield. This might imply that an excessive amount of wastewater is being transported upward via the soil rather than downward.
