- A septic tank ’s distribution box (or a D-box) is a container that receives the septic tank effluent and re-distributes it into the network of attached drain fields and pipes. To put it simply, its job is to evenly distribute the wastewater into the leach field.
Is a distribution box part of a septic system?
Distribution boxes are a small but very important part of a sewage disposal system. Effluent leaving the septic tank enters the distribution box; here the effluent must be uniformly divided and discharged to the drainfield system.
What’s a distribution box?
Definition of distribution box: a contrivance used to equalize the flow of septic-tank effluent into the various tile lines of the disposal field.
How much does it cost to replace a distribution box in a septic system?
Septic Distribution Box Replacement Cost Replacing a septic distribution box costs between $500 and $1,500. This component is also called the D-box. It is very important, responsible for controlling the even distribution of wastewater into the leach field.
How far away is a distribution box from a 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.
How far is your distribution box from your septic tank?
It’s usually somewhere near the edge of your drain field on the end that’s closest to your septic tank. Distribution boxes are usually only about 6 inches to 2 feet deep. This narrows your search, but you’ll need some other clues to help you find the exact location.
Is distribution box necessary?
The distribution box is a major part of the septic system being able to function properly is very important. If the distribution box isn’t working the right way you will soon be dealing with leach field failure.
Should there be water in septic distribution box?
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.
What is the average life of a septic system?
Age of the System It’s pretty common for a septic system to last 40 years or longer, which means if you buy a new home, you might never need to replace it. However, you might have an older home whose septic system has been in place for nearly half a century.
How long do distribution boxes last?
The steel tanks can last about fifteen to twenty years. They will need to be replaced after this time, as they tend to rust. It takes about forty years for a concrete septic tank to last.
How do you know if your leach field is failing?
The following are a few common signs of leach field failure: Grass over leach field is greener than the rest of the yard. The surrounding area is wet, mushy, or even has standing water. Sewage odors around drains, tank, or leach field.
Can a distribution box get clogged?
One of the most common septic tank problems arises when the distribution box is damaged or clogged, preventing the flow of water from the septic tank into the drainfield. In most cases, a qualified plumber can fix this problem quickly and easily before it becomes a serious issue for the household septic tank system.
Does every leach field have a distribution box?
Distribution Box: Most, but not all, systems have a d-box. Once the effluent is separated in the septic tank, the distribution box, located in the leach field, dispenses the effluent into the leach field.
Does a distribution box have a lid?
Pre-cast concrete Distribution Boxes are sold usually by local septic tank and system suppliers and typically include gasketed openings for the effluent distribution pipe connections and a flat concrete lid that simply mates with the flat edges of the D-box without a gasket and without use of a sealer.
What is a Septic Distribution Box?
What is a Septic Distribution Box and how does it work?
What is a Septic Distribution Box?
If you have a septic system, you are most certainly familiar with the fundamentals of the system as well as how to maintain your system. Most septic system owners are aware that having their tanks pumped every two to five years is necessary in order to maintain a working and effective system. There are, however, other components to the septic system, and one important component is the distribution box, which is also known as the d-box in some circles.
Parts of the Septic System
Photo courtesy of epa.gov A septic system is more than just a septic tank, as many people believe. The septic system works by channeling wastewater away from your home through pipes that lead to a holding tank where it may be treated. The effluent then passes through a series of additional pipes before reaching the distribution box. This little concealed box ensures that wastewater is distributed uniformly through field lines and onto the leach field (sometimes referred to as the drain field).
The Septic Distribution Box
The distribution box (also known as a d-box) is often constructed of concrete, fiberglass, or plastic materials. In terms of size and design, it might vary based on the septic requirements of the family. It is a box with an intake pipe to receive water from the tank and several outlet holes to disseminate the treated water across a network of field lines, as described above. These outlet holes can be adjusted to accommodate varying water flow conditions. It is often buried only one to three feet beneath the surface of the earth.
If you don’t mistreat your concrete d-box, it can survive for twenty years or more.
Potential Problems with Your Distribution Box
In the event that you have had your septic tank recently examined and pumped but are still experiencing plumbing issues, you may want to have your distribution box inspected and repaired. In order to work effectively, your distribution box must be level. If there is an issue with the box, it might cause difficulties with the system. A distribution box problem is most usually indicated by either a pattern of plumbing difficulties that persist even while your tank is operational or floods in the leach field (or both).
- Flooding induced by storms or strong rains may cause the d-box to overflow.
- Because of the freezing water, bottlenecks and potentially even breaks in the container might occur depending on the condition of your distribution box.
- Furthermore, trees or bushes that are placed too close together might cause harm if their roots grow down and shatter the pipes or the box that contains the pipes.
- The first step, though, is to be aware of the potential issues that may arise.
- If the distribution box is not supported by a solid base, it is more likely to alter position in the future.
- Remember to discuss this with your septic installation firm before beginning the installation of a new septic system.
- If you are experiencing freezing issues, the most likely cause is that your system does not have enough of a slope.
- It is more likely that the water will freeze if it is not moved through the operation rapidly enough.
- Simple things you can do as a homeowner will make a significant impact, such as flushing toilet paper after you use it.
Do not overburden your waste disposal with food scraps. Keep track of how much water you use in your home and be conscious of it. It is not permissible to drive over your leach field or to put huge trees or plants in that location.
How to Locate your Distribution Box
In contrast to your septic tank, your distribution box does not require regular pumping. However, it should be examined to minimize the high expense of unneeded repairs in the future. Close to the leach or drain field, the distribution box will be located a short distance downhill from the septic tank. You can seek for a depression in the earth in the vicinity of this location. Additionally, search for parallel depression lines in the ground (the field lines), which are approximately five feet apart, and trace them back until you reach the site of the box.
It will be helpful if you have a site plan, which is often provided to the homeowner at the time of installation.
It is also possible to have your septic provider locate it for you.
Please contact your septic provider if you have not had your distribution box examined in the past 30 days.

- What is a distribution box
- Why should you look for one
- And how to locate one
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 small 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 can also inspect the distribution box for damage and determine 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.
Types of Septic Systems
Septic system design and size can differ significantly from one neighborhood to the next, as well as throughout the country, due to a variety of variables. Household size, soil type, slope of the site, lot size, closeness to sensitive water bodies, weather conditions, and even municipal ordinances are all considerations to take into consideration. The following are 10 of the most often encountered septic system configurations. It should be noted that this is not an exhaustive list; there are several additional types of septic systems.
- Septic Tank, Conventional System, Chamber System, Drip Distribution System, Aerobic Treatment Unit, Mound Systems, Recirculating Sand Filter System, Evapotranspiration System, Constructed Wetland System, Cluster / Community System, etc.
Septic Tank
This tank is underground and waterproof, and it was designed and built specifically for receiving and partially treating raw home sanitary wastewater. Generally speaking, heavy materials settle at or near the bottom of the tank, whereas greases and lighter solids float to the surface. The sediments are retained in the tank, while the wastewater is sent to the drainfield for further treatment and dispersion once it has been treated.
Conventional System
Septic tanks and trench or bed subsurface wastewater infiltration systems are two types of decentralized wastewater treatment systems (drainfield). When it comes to single-family homes and small businesses, a traditional septic system is the most common type of system. For decades, people have used a gravel/stone drainfield as a method of water drainage. The term is derived from the process of constructing the drainfield. A short underground trench made of stone or gravel collects wastewater from the septic tank in this configuration, which is commonly used.
Effluent filters through the stone and is further cleaned by microorganisms once it reaches the soil below the gravel/stone trench, which is located below the trench.
Chamber System
Gravelless drainfields have been regularly utilized in various states for more than 30 years and have evolved into a standard technology that has mostly replaced gravel systems. Various configurations are possible, including open-bottom chambers, pipe that has been clothed, and synthetic materials such as expanded polystyrene media. Gravelless systems can be constructed entirely of recycled materials, resulting in considerable reductions in carbon dioxide emissions during their lifetime. The chamber system is a type of gravelless system that can be used as an example.
The key advantage of the chamber system is the enhanced simplicity with which it can be delivered and built.
This sort of system is made up of a number of chambers that are connected to one another.
Wastewater is transported from the septic tank to the chambers through pipes. The wastewater comes into touch with the earth when it is contained within the chambers. The wastewater is treated by microbes that live on or near the soil.
Drip Distribution System
An effluent dispersal system such as the drip distribution system may be employed in a variety of drainfield configurations and is very versatile. In comparison to other distribution systems, the drip distribution system does not require a vast mound of dirt because the drip laterals are only placed into the top 6 to 12 inches of soil. In addition to requiring a big dosage tank after the sewage treatment plant to handle scheduled dose delivery of wastewater to drip absorption areas, the drip distribution system has one major disadvantage: it is more expensive.
Aerobic Treatment Unit
Aerobic Treatment Units (ATUs) are small-scale wastewater treatment facilities that employ many of the same procedures as a municipal sewage plant. An aerobic system adds oxygen to the treatment tank using a pump. When there is an increase in oxygen in the system, there is an increase in natural bacterial activity, which then offers extra treatment for nutrients in the effluent. It is possible that certain aerobic systems may additionally include a pretreatment tank as well as a final treatment tank that will include disinfection in order to further lower pathogen levels.
ATUs should be maintained on a regular basis during their service life.
Mound Systems
Using mound systems in regions with short soil depth, high groundwater levels, or shallow bedrock might be a good alternative. A drainfield trench has been dug through the sand mound that was erected. The effluent from the septic tank runs into a pump chamber, where it is pumped to the mound in the amounts recommended. During its release to the trench, the effluent filters through the sand and is dispersed into the native soil, where it continues to be treated. However, while mound systems can be an effective solution for some soil conditions, they demand a significant amount of land and require regular care.
Recirculating Sand Filter System
Sand filter systems can be built either above or below ground, depending on the use. The effluent is discharged from the septic tank into a pump compartment. Afterwards, it is pushed into the sand filter. The sand filter is often made of PVC or a concrete box that is filled with a sand-like substance. The effluent is pushed through the pipes at the top of the filter under low pressure to the drain. As the effluent exits the pipelines, it is treated as it passes through the sand filtering system.
However, sand filters are more costly than a standard septic system because they provide a higher level of nutrient treatment and are thus better suited for areas with high water tables or that are adjacent to bodies of water.
Evapotranspiration System
Evaporative cooling systems feature drainfields that are one-of-a-kind. It is necessary to line the drainfield at the base of the evapotranspiration system with a waterproof material. Following the entry of the effluent into the drainfield, it evaporates into the atmosphere. At the same time, the sewage never filters into the soil and never enters groundwater, unlike other septic system designs. It is only in particular climatic circumstances that evapotranspiration systems are effective. The environment must be desert, with plenty of heat and sunshine, and no precipitation.
Constructed Wetland System
Construction of a manufactured wetland is intended to simulate the treatment processes that occur in natural wetland areas. Wastewater goes from the septic tank and into the wetland cell, where it is treated. Afterwards, the wastewater goes into the media, where it is cleaned by microorganisms, plants, and other media that eliminate pathogens and nutrients. Typically, a wetland cell is constructed with an impermeable liner, gravel and sand fill, and the necessary wetland plants, all of which must be capable of withstanding the constant saturation of the surrounding environment.
As wastewater travels through the wetland, it may escape the wetland and flow onto a drainfield, where it will undergo more wastewater treatment before being absorbed into the soil by bacteria.
Cluster / Community System
In certain cases, a decentralized wastewater treatment system is owned by a group of people and is responsible for collecting wastewater from two or more residences or buildings and transporting it to a treatment and dispersal system placed on a suitable location near the dwellings or buildings. Cluster systems are widespread in settings like rural subdivisions, where they may be found in large numbers.
Gravity Distribution: Do You Need a Drop Box or Distribution Box?
As I go around the nation and speak with people about gravity distribution, one of the most noticeable differences I see is the manner in which wastewater is carried to the trenches. The amount of effluent that flows to gravity distribution systems is directly proportional to the amount of sewage that enters the septic tank. For example, anytime sewage enters the septic tank, effluent from the septic tank flows to the soil treatment area. In the United States, the most popular design for onsite treatment has been gravity distribution of septic tank effluent for much of the history of the industry.
Effluent travels downhill from its origins to the septic tank, and then on to the soil treatment system in either a serial or parallel distribution pattern, depending on the situation.
The purpose of both systems is to distribute wastewater evenly, which is made possible by the use of a biomat, as illustrated in the illustration below. Until the biomat reaches the end of a trench or trenches, it is impossible to achieve a totally uniform dispersion.
Serial Distribution
If you use serial distribution, septic tank effluent will flow into the first trench until the sewage has ponded and the trench is filled to its capacity. When the first trench is full, the effluent flows into the second trench until it is full as well, and finally into the third trench. Before wastewater is transferred to the second trench, the first trench should have reached its maximum capacity. The system is constructed of a waterproof pipe that runs from the septic tank to the first drop box, which is the most typical location.
- The distribution pipe of the trench is connected to the drop box by an outlet located at the bottom of the drop box.
- With the exception of the sequence in which the effluent is delivered to them, the trenches operate independently, with each receiving effluent according to the rate at which it is received in that trench.
- Those who have a tendency to drain fast, maybe as a result of receiving more sunlight on the surface and experiencing greater water loss through evaporation during the warmer months, will get more effluent.
- Therefore, there is no increase in effluent flow rate into or through the second or third trenches just because they are located downhill from the first trench.
- Encourages the production of biomats and the flow of unsaturated water in sandy or coarse-textured soils. Sites with sloping terrain (no maximum slope restrictions)
- When varying trench lengths are required to accommodate structures, trees, and other obstacles
- Ability to create and link additional trenches as needed
- Adaptability to changing conditions. A quick check of the box and the ends of the trenches is necessary. There is no standing effluent in the solid line that connects the septic tank to the drop boxes.
Parallel Distribution
It is the distribution of septic tank effluent by gravity flow, which loads all portions of the soil treatment and dispersal system at the same time and in the same proportion. The parallel distribution system distributes wastewater flow into all trenches in the soil treatment unit at the same time, allowing for more efficient treatment. Trenches are built to have the same length and depth as one another and to be appropriate for the same type of soil, ensuring that treatment proceeds at the same rate in each trench throughout the project.
- Typically, a distribution box is a device designed to transport septic tank effluent concurrently and equitably by gravity to numerous parts of a soil treatment and dispersal system.
- If there is no backflow problem, there may be high hydraulic head between the top of the system (the distribution box) and the trenches even if there is no backflow problem.
- Throughout their operational life, all trenches must have the same length and must be capable of treating the same quantity of effluent as their neighboring trenches do.
- In order to alleviate the challenges connected with distribution boxes settling, several technologies have been devised and tested.
- When a leveling device is put at the end of the 4-inch outlet pipes, the outlet inverts will be slightly leveled, which is desirable.
- It is possible to insert an outlet adjuster into each pipe exiting the distribution box by placing it within the distribution box and into each pipe leaving the distribution box.
- When one side of the distribution box settles, or when freeze-thaw activity or shrink-swell activity in the soil causes the distribution box to go slightly out of level, this system has the benefit of allowing readjustments to be performed without having to re-level the distribution box.
The following are the applications and advantages:
- Sites with a 5 percent slope are level. In the case of sites with restricted separation to the limiting condition, the loss of elevation in the drop boxes may have an influence on the needed separation
- When it is possible to construct trenches of similar length
- In soils that include more clay and silt (as opposed to sand), to aid in the distribution of wastewater down the length of the trench

Should a Septic Tank Distribution Box be Full of Water?
When we initially moved into our present home, which included a septic tank, I knew I wanted to learn everything I could about septic systems before we could utilize it. I was aware that they are buried underground, that they must be pumped out on a regular basis, and that they may be pricey. That was pretty much the extent of my knowledge. However, the distribution box has suddenly emerged as one of the components that is strangely intriguing. I honestly have no idea why this is happening. It took us a couple of years to realize that we even had a distribution box in the first place.
- If you’re wondering whether or not a distribution box should be filled with water, keep reading.
- After leaving the septic tank and making its way to the drain field, effluent water first passes through the distribution box.
- An overflowing distribution box indicates blocked leach lines or an overflowing drain field as the cause of the overflow.
- Of course, the bad news is that it is possible that there will be a serious problem with the leach field.
What is a Septic System Distribution Box?
First and foremost, it should be noted that not all septic systems are equipped with a distribution box. Older systems may not be able to do so. Given that you’re asking why one would be full, I’m going to presume you’re aware that you have one, correct? Despite its importance, the distribution box is one of the most underappreciated components of a sewage system. Basic systems include one pipe running from the home to the septic tank on one side, with all of the waste water from the house going into the tank.
- Meanwhile, microorganisms are hard at work breaking down all of the unpleasantness around the clock.
- (These are the same item, yet some people refer to it as one and others as the other.) (It’s pronounced Potahto.) The drain field is comprised of a number of long plastic tubes (usually 2–6) that have holes in them.
- The distribution box is responsible for ensuring that the effluent water is distributed uniformly amongst all of the leach lines.
- The pipe from the septic tank is linked to one end of the pipe, and then each of the leach lines is attached to the other end of the pipe.
Flowing water from the septic system enters the D-box, where it is distributed equally into each of the leach lines as it increases in water level. This movie provides a very succinct review of everything. It’s only one minute in length.
Why is My Distribution Box Full of Water?
It’s clear now that you understand how the distribution box works (assuming you didn’t already know how it worked, that is), why it shouldn’t be filled with water. Maybe if you were experiencing a really strong rain that had been going on for hours and then did a load of laundry, the D-box would momentarily be full since the leach field was saturated from the heavy rains and adding a washing machine full of water would make the D-box temporarily full. But even if it were, I’m not convinced it would be completely packed.
So, what may be the source of your D-overflowing box’s water supply?
You could have a clog
If the distribution box is consistently full, it is reasonable to conclude that there is a problem with the water departing or entering the system. This means there might be an obstruction in one or more of the leach lines, preventing water from flowing into them or draining out of them at a rapid rate. Roots from adjacent trees (which shouldn’t really be nearby) might be growing into the leach lines, and this could be the cause of the problem. It should not be choked by grass or wildflowers growing above the area, as the leach lines should be at least 18″ below the surface of the ground.
Alternatively, it might be clogged with debris from the septic tank, particularly from the sludge or scum layers.
If only the effluent water is present at the level of the outlet pipe, then the tank has not been pumped or treated frequently enough, and either the scum layer (fats, oils, floating things) has become too thick to allow it to drain too far down into the tank, or the sludge layer (poo) has become too thick to allow it to drain all the way up to the outlet level.
The Drain Field is Failing
I believe this is the most likely possibility, however it is not encouraging news for the time being. If the drain field is failing, it indicates that the water is not draining as rapidly as it should, and as a result, the water is pooling in the leach lines, leaving the water in the distribution box with nowhere else to go. Drainfields are susceptible to failure if the earth underneath them has become compacted as a result of vehicles driving over or parking on them. Aside from that, if you have an above-ground pool over the leach field, this can also cause the earth to be compacted.
I recall a homeowner whose neighbor had a lot of water overflow from his land, which I found to be a nuisance.
I’m sorry, but I can’t recall if it was from a small farm or just from severe rains, but the lay of the ground naturally funneled the runoff into the first man’s yard, filling his drainfield to dangerous levels.
Fixing a Failing Drainfield
I don’t want to dive too much into the details of how to repair a failing drainfield at this point, but there are a variety of methods available depending on the situation. The land may be fractured if you put large amounts of air into it at high pressures and speeds. It’s possible that you’ll have to replace the complete drainfield or only a few lines. It depends, which I realize is not a very helpful response. They live next door to us, and their drainfield was wrongly placed long before they purchased the property.
It was a flop.
Catywumpus D-Box
The only other thing that may be causing the distribution box to remain full is if it is extremely slanted up in some way, such that the pipes leading to the leach field are angled up and the water is just having a difficult time getting into the distribution box. It would take a significant movement in the D-box to create that type of a complication. It is not impossible, but it is extremely unlikely.
Can I Fix My Clogged Leach Lines?
It is quite possible to check for and attempt to remove a blockage on your own if you are physically capable of doing so. If you’re not sure, give a septic company a call and inquire about how much it might cost for them to come out and inspect it. That alone could be enough to spur you on!
Sewer Jetting
If the problem is that the leach lines are clogged with things like dirt, biomat (biological material), or oily sludge, you may be able to solve the problem by using a sewer jetter kit such as this one to clean it out yourself. Pressure washer attachments and a range of heads are available for these tools. Simply attach the proper hose head to each leach line and feed it into the appropriate hose fitting. Turn it on and see if you can clear any clogs out of it. At least one of the heads is intended to spray forward, blasting up the blockage, and rearward at the same time, flushing the debris out of the line when you remove the home from the water supply.
It will begin to function when the level of water in the distribution box begins to fall.
Inquire with your local hardware shop to discover whether they provide these services on a rental basis.
Drain Line Auger
If the problem is that the leach lines are clogged with things like dirt, biomat (biological material), or oily sludge, you may be able to solve the problem by using a sewer jetter kit such as this one to clean them out. Pressure washer attachments and a range of heads are available for purchase separately. Simply attach the proper hose head to each leach line and feed it into the corresponding hose head. Try to clear any blockages out by turning it on. At least one of the heads is intended to spray forward, blasting up the clog, and rearward at the same time, flushing the debris out of the line when you remove the home from the water supply system.
It will begin to function when the level of water in the distribution box begins to fall significantly. The method is demonstrated in this really brief video. Inquire with your local hardware shop to see whether they provide these services on a temporary basis.
I do hope you are able to fix your issue quickly, easily, and inexpensively!
A septic system is a type of on-site recycling system that processes wastewater and recycles it back into the environment. A septic system may perform its functions safely and efficiently for a long period of time if it is properly planned, constructed, and maintained. Failure due to improper design, installation, usage, and/or maintenance can result in a premature and expensive failure. To safeguard your investment and the environment, we encourage you to learn how your system works, to use it appropriately, and to keep it in good working order.
- Septic Tank (also known as a septic tank): Waste water is channeled from the residence to the septic tank by gravity.
- Bacteria breakdown a portion of the solids, resulting in the formation of sludge.
- Baffles fitted at the tank’s inlet and exit help to prevent scum and particles from escaping through the openings.
- There will be no non-biodegradable items in a well kept septictank; the sludge, scum, and grease levels will be less than one-third the total liquid level in the tank; baffles will be installed and correctly designed; and the filter, if applicable will be generally clean and unobstructed.
- This is accomplished by the use of a pump or siphon.
- The operation of an effluent pump is dependent on power.
- When an effluent pump is used, the pump’s operation is triggered by on and offfloats that are linked to the pump.
An alarm system, as well as the control box, are frequently installed in the house.
As soon as the effluent has been separated in the septic tank, it is dispensed into the leach field via thedistribution box, which is placed inside the leach field.
Drain field: A solid pipe travels from the septic tank to the drain field where wastewater is routed into one or more perforated pipes arranged in trenches or beds of gravel, as well as a perforated concrete structure, to be disposed of properly.
Here, the water gently seeps into the dirt beneath the surface.
The cleaned wastewater then either travels into the groundwater or evaporates from the soil, depending on the circumstances.
Planting trees, on the other hand, is not recommended since the roots of huge plants might choke or damage the pipes.
Cracking pipes, causing the distribution box to settle and effluent to flow unevenly into the drain field, and/or compacting soils, smothering the leach field are all possible consequences of these operations.
Distribution Boxes
- Keeping an eye on your septic distribution box may assist guarantee that your septic system is running at peak capacity, which means that your wastewater is being dispersed evenly across your drain field and away from the house. A septic distribution box’s condition should be checked at least once every eight to twelve years throughout its first eight to twelve years of operation. Overloading will occur if the water levels in each trench receiving wastewater flow are not equal in each trench. This is the point at which septic system problems manifest themselves, and it is you and your property that bear the consequences. A properly functioning distribution box is critical to the entire operation of the system

The Top Ten Septic System Myths
Dennis Hallahan, P.E., posted a message on We’ve all heard them at some point. Is Biomat a terrible thing? Is an equal distribution box or header manifold provided by a distribution box or header manifold? Recently, I delivered a webinar in which I debunked some of the most commonly held beliefs about septic systems using scientific evidence. As an industry, it is critical to communicate a consistent science-based message to the public about the fallacies that plague so many people today. Let’s take a look at some of the frequent fallacies surrounding the onsite wastewater sector.
Myth: A distribution pipe provides equal distribution.
Perforated distribution pipes do not offer “equal distribution” inside gravity-fed onsite wastewater treatment systems, according to the findings of several research. Although a biomat will grow and offer equal distribution under gravity flow, pressure dosing is a mechanical way that may be used to achieve this.
Myth: A distribution box or header manifold provides equal distribution.
False While distribution boxes or manifolds are placed level when they are first built, they will settle over time as a result of the natural environment.
The settlement in conjunction with low flow (gravity flow out of the septic tank is only a trickle, and the 4″ pipe is huge in comparison to the flow) created a difficult situation. The flow discharging out will therefore seek the lowest inversion and will not give a fair distribution of energy.
Myth: Biomat is bad.
False The development of a biomat is inevitable in all systems. The biomat will aid in the distribution and treatment of the onsite wastewater treatment system in a more even and efficient manner.
Myth: Venting a distribution trench provides better treatment and/or performance.
What are your thoughts? Due to the high energy expenditure required for the process of transferring oxygen from the gaseous state to the liquid state, only a small advantage is realized. However, venting can be advantageous on an individual case-by-case basis since it gives oxygen. However, there is no scientific evidence to determine just how much venting a system might aid offer better therapy.
Myth: Design Flow = Actual Flow
FalseDesign flow always involves a factor of safety that is greater than the actual flow of the system that will be implemented in real life.
Myth: Roots are bad for the drainfield.
Partially correct, primarily incorrect. Roots have the capacity to assist in the removal of water and nutrients from a system. Roots can become an issue if they get in the way of the line that runs from the home to the septic tank, which is responsible for transporting solids. However, root infiltration into a drainfield beyond the septic tank is not necessarily detrimental. Although roots should not be promoted, they are not inherently bad.
Myth: All septic systems fail.
False It’s critical to consider the design life of an onsite wastewater treatment system while planning a system. Septic systems will last 20 years, according to the majority of people. A septic system that has to be replaced before the end of its intended life would be deemed a failure. All items, including tires, roof shingles, bridges, and other similar structures, have a design life. It is important to distinguish between replacing a system after it has provided years of service and failing to replace a system.
Myth: Stone within the drainfield provides treatment.
False The treatment levels of drainfields constructed within and without stone have been investigated in several research. There was no discernible difference between the treatments, according to the findings. This is due to the fact that the soil is responsible for the treatment of wastewater in an onsite wastewater treatment facility.
Myth: “The best system is…” Can such a statement be made?
False There is no one optimal onsite wastewater treatment system since each site is different, each code is different, the complexity of installation differs, the amount of OM required, and so on. Best system is the one that will achieve the specified objective (i.e., comply with health rules) at the lowest possible costs.
Myth: Sanitary sewers pollute less than decentralized systems.
FalseSanitary sewers are issued CSO licenses, which is a special permission that allows them to release raw wastewater during overflow occurrences like as heavy rain events. On-site wastewater treatment systems treat all of the wastewater that enters the system. These are just a few of the most prevalent falsehoods I’ve come across throughout my many years working in the business.
Have you heard any more urban legends? Send me an email if you have any, I’d love to know about them! As I previously stated, the webinar I conducted provides more in-depth information on each of these fallacies. You may view the webinar recording by clicking here. a little about the author:

Septic System Basics
Many homes in upstate New York are so far away from one another that it would be prohibitively costly to establish a sanitary sewage system. Septic systems are used by homeowners in these situations to meet their wastewater management requirements. For waste treatment and water disposal, these systems include a septic tank and some form of drain field system. The remainder of this essay will discuss how they operate as well as the fundamentals of septic systems. It is a simple matter of digging down into the yard and burying a large concrete or plastic tank.
Wastewater enters the tank from one end and exits the tank from the other end of the tank.
Scum is formed when everything that floats rises to the surface and creates a layer at the top of the water column.
In the middle, there is a layer of water that is relatively transparent.
Wastewater enters the septic tank through the sewage lines in the home, as indicated in this illustration: As additional water is introduced into the tank, it displaces the water that has previously been introduced.
The exit baffle, which is a bulkhead or pipe in the septic tank that prevents the drain field from being blocked with sediments, keeps the drain field free of solids.
Typically, drain fields are constructed of perforated pipes that are buried in gravel-filled ditches.
It is buried in a trench that is 2.5 to 5 feet deep and 2 feet wide, with the perforations spaced every few inches.
The size of the drain field is decided by the local construction requirements as well as the number of bedrooms in the house, among other factors.
An ordinary septic system is typically driven by gravity.
It is a totally passive mechanism in all respects.
Regardless of the kind of septic system installed in your house, regular pumping and cleaning are essential to maintain the system operating properly.
We recommend that you get your tank pumped and cleaned every two to three years in order to maintain optimum operation and extended lifespan. If you have any additional concerns about septic system fundamentals, please do not hesitate to contact our office at (518) 584-1048.
