Factors Determining Septic Tank Depth If a site has bedrock or large boulders close to the surface, the tank may be located elsewhere; the further the tank is located from the building, if the system uses gravity to move sewage, the deeper the tank will be.
- Another factor is related to the depth of sewage line from the property. In cold climates as well, the latent heat from ground along with bacterial action from the sewage prevents it from freezing. Any septic tank should not be buried excessively underground, as it can damage it and will hamper its proper functioning.
How deep should a septic system be buried?
The general rule of thumb is that most septic tanks can be buried anywhere from four inches to four feet underground.
What causes a septic tank to cave in?
Septic tanks can collapse for a variety of reasons. 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 deep are most septic tanks buried?
Over time, all septic tanks fill up with solids and require pumping to continue working as they should. Often, septic tank lids are at ground level. In most cases, they have buried anywhere from four inches to four feet underground.
What is a deep trench septic system?
The trench system consists of shallow, level excavations, usually 1-5 feet deep and 1-3 feet wide. The excavated area is usually filled with 6+ inches of some porous medium, like gravel.
How deep are drain fields buried?
A typical drainfield trench is 18 to 30 inches in depth, with a maximum soil cover over the disposal field of 36 inches.
How long do septic tanks last?
A septic system’s lifespan should be anywhere from 15 to 40 years. How long the system lasts depends on a number of factors, including construction material, soil acidity, water table, maintenance practices, and several others.
How can you tell if a septic tank collapse?
The first signs of a failing septic system may include slow draining toilets and sinks, gurgling noises within the plumbing, sewage odors inside, continuing drainage backups, or bacteria in the well water. If any of these symptoms exist, check for more pronounced indications of a septic system failure.
How do I know if my septic tank is failing?
8 Signs of Septic System Failure
- Septic System Backup.
- Slow Drains.
- Gurgling Sounds.
- Pool of Water or Dampness Near Drainfield.
- Nasty Odors.
- Unusual, Bright Green Grass Above Drainfield.
- Blooms of Algae in Nearby Water.
- High Levels of Coliform in Water Well.
How do you tell if your septic tank is full?
How to tell your septic tank is full and needs emptying
- Pooling water.
- Slow drains.
- An overly healthy lawn.
- Sewer backup.
- Gurgling Pipes.
- Trouble Flushing.
How often should a septic tank be pumped?
Inspect and Pump Frequently The average household septic system should be inspected at least every three years by a septic service professional. Household septic tanks are typically pumped every three to five years.
Will metal detector find septic tank?
If it’s Concrete or Steel, Use a Metal Detector. Based on your conclusions in Step 3, if your septic tank is likely made from concrete or steel, a metal detector can make the task of locating it much easier. But not just any metal detector will do.
What happens if my land doesn’t perk?
NO PERC, NO HOUSE On rural sites without municipal sewage systems, a failed perc test means that no house can be built – which is why you should make any offer to purchase land contingent on the site passing the soil and perc tests.
Can a leach field be too deep?
Drain Field Depth The result is a drain field about 3 to 4 feet deep. Sometimes, however, a drain field may need to be a bit shallower and can result in drain pipes as close to the surface as 6 inches. Underground obstacles can cause this situation.
Do all septic tanks have filters?
First, not all septic tanks have a filter, especially the older septic tanks. Now many government agencies require or recommend a filter when a septic tank is installed. Cleaning a septic tank filter is different than pumping out a septic tank and cleaning it.

Discovering the location of your septic tank in your yard, as well as what may be grown near or on top of it, will help you determine how much of your yard is suitable for regular gardening.
You May Not Know
Despite the fact that it appears to be something that every homeowner should be aware of, understanding how deep a septic tank is buried can be difficult to determine. Perhaps you forgot about the septic tank after it was installed years ago, or perhaps you are moving into a house that already has a septic tank constructed in previously. Whatever the situation, determining the depth of your septic tank can be a challenging task under the circumstances, especially if you are unsure of the location of the lids.
How to Locate Your Septic Tank
Perhaps you’re unsure of the location of your septic tank on your property and are attempting to identify it on your own. There are really quite a few quick and simple methods for determining the location of your tank without having to go through a lengthy process. The first method is to follow the path laid out by your sewer lines. Typically, the tank and your drain field will be placed along a line parallel to the sewage line that goes from your property out to the street. Your home’s crawl area or basement may even have a four-inch sewage line that leads away from the structure of the building.
- Follow the pipe all the way across the yard, checking every few of feet to make sure you’re still on the right track, and then turn around.
- When you don’t feel like digging around in your yard, you can always look up your house’s address in the county records database.
- Diagrams with measurements and even the particular location of where the septic tank is located should be included in this document.
- You can also choose to dig your lid out from under it.
- This is what will tell you how many lids are on your septic tank and how many are missing.
- The majority of septic tanks are rectangular in shape and measure around in the neighborhood of 5′ x 8′ in size.
- If you are unable to determine the position of your septic tank using a probe, you will need to do a shallow excavation around the perimeter of the tank using a shovel in order to finally locate the lid.
- First, look for visual cues to help you.
- There is no doubt about it, this will tell you exactly where the tank is located beneath.
- Take a look at the plumbing in your structure, as well as the overall state of the property, to get a good sense of where the tank is situated.
It will be full to just a few inches below the underside of your tank lid when your tank is fully charged to its regular level of filling capacity. If the lid is constructed of plastic, fiberglass, or steel, the upper surface of the lid may have some variation in color or texture.
Where Should the Septic Tank Be Located?
If your property does not presently have a septic tank, but you are interested in the possibility of installing one, it is critical that you understand where it should be installed. Ordinarily speaking, most septic tanks will be situated between 10 and 25 feet away from the house. You should bear in mind that septic tanks cannot and should not be located any closer than five feet from your residence. Using a probe, you may search for flat concrete to determine whether or not a tank has previously been put on a property that you have recently purchased.
Planting Above a Septic Tank
Even though it may not appear to be the finest idea in the world, putting vegetation over a septic tank may really be perfectly acceptable as long as you choose the appropriate plants to grow. Not only is it perfectly OK to do so, but it may also be rather helpful depending on what you are planting and harvesting. It is possible to avoid erosion in your tank with the correct sort of vegetation, and it is even possible to absorb some of the additional moisture that might accumulate in your drain field.
- Perennial plants and grasses (as previously indicated) are the ideal kind of plants to use in and around your drain field and septic tank.
- You can use non-woody ground covers for a similar purpose as you do with woody ground covers.
- Take, for example, the expanding environment.
- If you don’t have access to enough sunshine, you might want to choose a shade garden plant instead.
- Keep in mind that the soil that surrounds the septic tank drain field will typically be wetter than the surrounding soil in the rest of the yard.
- As a result, choose a perennial such as a hollyhock, wild violet, or bee balm to ensure that you cover all of those bases when planting.
- A septic system beneath these plants does not imply that deer will avoid the area because of its presence on your property.
- Something like a spring bulb or an attractive grass that the deer aren’t generally interested in eating.
Plants That You Don’t Want to Grow
Just because you have the option of planting over your septic tank does not mean that everything is appropriate for this situation. A few plants should be avoided at all costs while landscaping around your septic tank, particularly huge trees that are known for their rapid growth. On the same vein, shrubs and trees with aggressive root systems are some of the worst plants to grow around your home. These roots will shoot out in quest of water, and they will not be concerned with where they locate it.
The infiltration of those roots into your septic drain field might result in catastrophic damage to your septic tank and drain field.
It’s possible that you’ll need a complete replacement.
Many other plants have strong root systems that you should avoid growing anywhere near your septic tank or drain field, and there are lots of them.
How Your Septic System Works
It is possible that understanding how your septic system operates may help you better manage, maintain, and care for it. Aside from that, it is just a large tank buried in the ground that collects your waste (which is true, but still). In remote locations, there may be a deficiency in sewage infrastructure. Because not every rural location is the same, it is not a given that septic systems will be required in your local rural area. The septic tank, in any case, serves as a form of wastewater treatment facility when there are no sewage lines available.
- The tank is designed to be waterproof, ensuring that your wastewater does not leech into the surrounding environment.
- Solids sink to the bottom of the container, scum rises to the top of the container, and liquids sit in the center of the three levels described above.
- The wastewater that is being discharged from your home is the cause of the exit.
- This liquid is carried out of your home through a pipe and into a bigger portion of your sanitary sewer system.
- Your drain is typically comprised of a network of perforated PVC pipes that are put underground in trenches to collect water and waste.
- Because the drains are perforated, the wastewater is allowed to seep out into the crushed gravel or stone, and then eventually into the surrounding soil.
- The natural evaporation process will then take care of any surplus moisture in the soil, unless you do something to prevent the water from flowing out of the pipes.
How to Plan a Septic Field
The tank is only one component of the whole equation. You’ll also need a drain field to catch all of the liquid waste that will be generated. When you are planting around your septic tank, the drain pipes are the most significant source of worry. Having those aggressive roots infiltrate and ruin your septic drain system is the very last thing you want. When this occurs, it can prevent your septic tank from emptying correctly and potentially cause it to get contaminated by groundwater. According to a solid rule of thumb, the less horticultural labor you have to do in close proximity to your septic tank, the better.
Just remember that they must be planted every year, so keep that in mind while planting them.
The first step is to fill in the septic drain field with earth.
In the second instance, too much mulch is being applied to the area in question. The third issue is that you may be watering your plants more than you should be. All three of these factors can impair the capacity of your drain field to evaporate in a typical manner.
How a Septic System Works – and Common Problems
This Article Discusses Septic Tanks are a type of septic tank that is used to dispose of waste. Field Sizing and System MaintenanceProblems with the Leach FieldSystem Performance Questions and comments are welcome. See Also: Septic System Frequently Asked Questions Articles on SEPTIC SYSTEM may be found here. In locations where there are no municipal sewage systems, each residence is responsible for treating its own sewage on its own property, which is known as a “on-site sewage disposal system,” or septic system, more popularly.
One of the most commonly seen types of leach field is composed of a series of perforated distribution pipes, each of which is placed in a gravel-filled absorption trench.
The wastewater is collected in the septic tank once it has been discharged from the residence. Septic tanks are normally between 1,000 and 2,000 gallons in capacity and are composed of concrete, strong plastic, or metal, depending on the model. Highly durable concrete tanks, which should endure for 40 years or more provided they are not damaged, are the most common. Many contemporary tanks are designed with two chambers in order to maximize efficiency. Household wastewater is collected in the septic tank, where it is separated and begins to degrade before being discharged into the leach field.
- In the tank, oil and grease float to the top of the tank, where they are known as scum, while solid waste falls to the bottom, where they are known as sludge.
- Bacteria and other microorganisms feed on the sediments at the bottom of the tank, causing them to decompose in an anaerobic (without oxygen) process that begins at the bottom of the tank.
- Solids and grease must be pushed out of the system on a regular basis in order for it to continue to function effectively.
- Each gallon added to the tank results in one gallon being discharged to the leach field, leach pit, or other similar treatment facility.
A large amount of water delivered too rapidly to the tank may discharge untreated effluent, along with oil and particulates, into the leach field, where it may block the field and cause a backup.
When used properly, a leach field (also known as a “drain field”) is a series of perforated pipes that are typically buried in gravel trenches 18 to 36 inches below grade — deep enough to avoid freezing, but close enough to the surface that air can reach the bacteria that further purify the effluent (see illustration below). As little as 6 inches might separate you from the ground surface, depending on your soil type and municipal regulations. It is customary to cover the perforated pipes with approximately two inches of gravel and a layer of topsoil that is 18 to 24 inches in depth.
- Grass is often sown above the ground.
- The leach field is comprised of rows of perforated pipes in gravel trenches that are used to spread wastewater over a vast area in order to further purify it.
- A bacteria-rich slime mat forms where the gravel meets the soil, and it is responsible for the majority of the water purification work.
- Despite the fact that wastewater freezes at a far lower temperature than pure water, freezing is still a hazard in cold areas.
- The leftover pathogens are converted into essential plant nutrients by these organisms, while sand, gravel, and soil filter out any solids that remain.
- If the system is operating effectively, the filtered wastewater will return to the aquifer as naturally clean water that is suitable for human consumption at this stage.
- Alternative systems may be permitted in situations when traditional leach fields are unable to function properly owing to poor soil conditions or a high water table.
- Special systems may also be necessary in regions where there are flood plains, bodies of water, or other ecologically sensitive areas to protect against flooding.
SIZING THE LEACH FIELD
Using perforated pipes put in gravel-filled trenches, the drain field is sized to accommodate the number of beds in the house. In order for the system to function successfully, the leach field must be appropriately sized for the soil type and amount of wastewater, which is normally determined by the number of bedrooms in the house. In order for the liquid to seep into the soil, it must be permeable enough to do so. As a result, the denser the soil, the larger the leach field that is necessary.
- Better to have surplus capacity in your system than to have it cut too close to the bone.
- Septic tank backup into your house, pooling on the surface of the earth, or polluting local groundwater are all possibilities if the ground is incapable of absorbing the liquid.
- Dense clay soils will not absorb the liquid at a sufficient rate, resulting in a backlog.
- If the soil is mostly composed of coarse sand and gravel, it might drain at such a rapid rate that untreated sewage can poison the aquifer or damage surrounding bodies of water.
- Alternative systems may be permitted in situations when traditional leach fields are unable to function properly owing to poor soil conditions or a high water table.
These systems sometimes cost twice or three times as much as a regular system and require significantly more upkeep. Near flood plains, bodies of water, and other ecologically sensitive places, special systems may also be necessary to protect people and property.
SEPTIC SYSTEM CAREMAINTENANCE REQUIRED
If you take good care of your system, you will be rewarded with years of trouble-free operation. Pumping the septic tank on a regular basis is necessary to remove the particles (sludge) and grease layer (scum) that have built up in the tank. The solids will ultimately overflow and spill into the leach field, decreasing its efficacy and diminishing its lifespan if this is not done. The rehabilitation of a clogged leach field is difficult, if not impossible; thus, constant pumping is essential!
- Cooking fats, grease, and particles may also wash into the leach field if the tank is too small for the amount of water being used or if the tank is overcrowded on a regular basis.
- Extra water from excessive residential consumption or yard drainage can overwhelm the system, transporting oil and particles into the leach field and causing it to overflow.
- In addition, don’t try to complete a week’s worth of laundry for a family of five in a single day.
- To minimize overburdening the system, the following measures should be taken:
- Distribute your washing loads and other high-water-use activities across the week
- And In the kitchen and bathroom, use low-flow appliances, faucets, and fixtures. Toilets, in general, are the source of the greatest amount of water use. Water should be diverted away from the leach field from the yard, gutters, and basement sump pumps.
In addition, refrain from flushing sediments, strong chemicals, and just about anything else down the toilet or sink other than biological waste and white toilet paper. Avoid using garbage disposals in the kitchen. If you really must have one, keep it for small non-meat bits only. Avoid flushing chemicals or paints down the toilet since many chemicals can destroy beneficial microorganisms or cause water contamination in the surrounding area. Avoid flushing the following down the toilet:
- Grease, fats, and animal scraps
- Paints, thinners, chemicals, and pharmaceuticals
- And a variety of other materials sanitary napkins, tampons, and other supplies Paper towels and disposable diapers are examples of such products. Egg shells, coffee grounds, and nut shells are all good options. Antibacterial soaps and antibiotics are available.
It is preferable to put grass over the leach field and to refrain from driving or parking in the vicinity. Excessive weight placed on top of the drain field might compress the earth, diminishing its efficiency as a drain field. Drain pipes can also become clogged by trees and plants with invasive roots. In order to prevent damage to the leach field, the following measures should be taken:
- Heavy machinery should not be driven, parked, or stored on top of the leach field (or septic tank). Placement of a deck, patio, pool, or any other sort of construction over the leach field is prohibited. Remove any large trees or other plants with deep roots from the leach field. Grass is the most effective groundcover.
Even with careful use and routine maintenance, however, leach fields are not guaranteed to survive indefinitely. It is inevitable that the soil will get saturated with dissolved elements from the wastewater, and that the soil will be unable to absorb any more incoming water. The presence of an odorous wet area over the leach field, as well as plumbing backups in the house, are frequently the first indicators that something is wrong. Many municipalities mandate septic system designs to incorporate a second “reserve drain field” in the case that the first field fails.
A well constructed and maintained system should last for at least 20 to 30 years, if not longer than that. After a few tears, the initial field will naturally heal and may be used once again when the situation calls for it to be. More information on Septic System Maintenance may be found here.
SEPTIC SYSTEM PERFORMANCE PROBLEMS
Poor original design, abuse, or physical damage, such as driving heavy trucks over the leach field, are the root causes of the majority of septic system issues. The following are examples of common situations that might cause a septic system to operate poorly: Plumbing in the home. obstructed or insufficient plumbing vents, a blockage between the home and the septic tank, or an insufficient pitch in the sewer line leading from the house are all possible causes. Sewage tank to leach field connection Septic tank and leach field blockage caused by a closed or damaged tank outlet, a plugged line leading to the leach field caused by tree roots, or a blockage caused by sediments that overflowed from the tank Piping in the leach field.
- Most of the time, tree roots do not make their way through the gravel bed and into the perforated pipe.
- Reduced flows, achieved through the use of flow restrictors and low-flow faucets and fixtures, may be beneficial.
- Because of the seasonal high water table, the soil around the trenches might get saturated, reducing the soil’s ability to absorb wastewater.
- This may frequently be remedied by adding subsurface drains or curtain drains to intercept the water flow into the leach field region and to lower the water table in the immediate area around the drainage system.

How deep are septic tank lines buried?
Depth. According to the Clemson Cooperative Extension, the pipes should be placed in the leach field at a depth of at least 6 inches and most likely between 18 and 36 inches deep. Because soil and water tables differ from state to state and even within states, each leach field must be designed specifically for that location. 4 feet and 8 inches What is the depth of a 1000-gallon septic tank, in the same way?
|Steel Septic Tank Typical Dimensions|
|Steel Septic Tank Size (Gallons Capacity)||Tank Length (Inches)||Tank Depth (Height) (Inches)|
It has also been debated if a septic tank might be excessively deep. The depth of the septic tank should not be more than is necessary, because effluent is normally transported from the septic tank to the drainfield by gravity as well as by pumping or suction. Plumbers often build sewage lines to slope down from the inlet to the outlet at a rate of 1/8″ per foot to 1/4″ per foot of linear run of the waste pipe, depending on the kind of waste pipe. Should the lids of septic tanks be buried?
A typical septic tank will have all of its components including the lid buried between four inches and four feet underground in the vast majority of situations. You’ll have to dig for it unless the septic tank has special risers that keep the lid at ground level.
Septic Tank Depth
Trevor, I am not sure how much heat is generated by the biological activity in a septic tank, but I suspect that an active tank will generate more than one in “vacation” mode. If you are a two person household like mine, then the total amount of warm water and “food” put into the tank may not be very much in general. If you are away from home for an extended period of time, it is possible that the temperatures in the tank will stratify. Depending on soil types and moisture levels, your actual frost line depth might approach the set depth of your tank.
- I set my 56″ tall tank with the bottom 6′ below finished grade to ensure that ground warmth would always be above freezing point.
- It should also help keep the little bugs more active when in use by limiting heat losses.
- Taking an extended winter vacation when local temperatures are dropping down to -5F sounds a bit risky to me.
- I do not know whether this could crack the tank.
- The inlet and outlet pipes may be of more concern as they too are quite close to the surface.
- The run was long and crossed a driveway, which together dropped the soil temperatures well below freezing.
- Around here the word is don’t put any pipes to or from your tank under a driveway.
- I am not quite sure if that is valid, but I made sure that all lines in and out of the tank are well away from traffic.
- Too little cover will not redistribute the foot print of a tire safely.
- Maybe Michael can add real life observations about the inlet and outlet risk for your area.
What size of septic tank do I need?
Probably one of the last things on your mind when you are constructing a new house is the location of your septic system.
After all, shopping for tanks isn’t nearly as entertaining as shopping for cabinetry, appliances, and floor coverings. Although you would never brag about it, your guests will be aware if you do not have the proper septic tank placed in your home or business.
septic tanks for new home construction
The exact size of the septic tank is determined mostly by the square footage of the house and the number of people who will be living in it. The majority of home septic tanks have capacities ranging from 750 to 1,250 gallons. A 1000 gallon tank will most likely be required for a typical 3-bedroom home that is smaller than 2500 square feet in size. Of course, all of this is dependent on the number of people who live in the house as well as the amount of water and waste that will be disposed of through the plumbing system.
For the most accurate assessment of your septic tank needs, you should speak with an experienced and trustworthy sewer business representative.
planning your drainfield
Here are some helpful hints for deciding where to locate your drainfield when you’re designing it.
- Vehicles should not be allowed on or around the drainfield. Planting trees or anything else with deep roots along the bed of the drain field is not recommended. The roots jam the pipes on a regular basis. Downspouts and sump pumps should not be discharged into the septic system. Do not tamper with or change natural drainage features without first researching and evaluating the consequences of your actions on the drainage field. Do not construct extensions on top of the drain field or cover it with concrete, asphalt, or other materials. Create easy access to your septic tank cover by placing it near the entrance. Easy maintenance and inspection are made possible as a result. To aid with evaporation and erosion prevention, plant grass in the area.
a home addition may mean a new septic tank
Do not make any big additions or renovations to your house or company until you have had the size of your septic system assessed. If you want to build a house addition that is more than 10% of your total floor space, increases the number of rooms, or necessitates the installation of new plumbing, you will almost certainly need to expand your septic tank.
- For a home addition that will result in increased use of your septic system, your local health department will require a letter from you that has been signed and authorized by a representative of your local health department confirming that your new septic system is capable of accommodating the increase in wastewater. It is not recommended that you replace your septic system without the assistance of a certified and competent contractor.

common septic questions
Here are some of the most frequently asked questions by our septic customers.
How do I determine the size of my septic tank?
If you have a rectangular tank, multiply the inner height by the length to get the overall height of the tank. In order to find out how many gallons your septic tank contains, divide the number by.1337.1337
How many bedrooms does a 500-gallon septic tank support?
The exact size of the septic tank is determined mostly by the square footage of the house and the number of people who will be living in it. The majority of home septic tanks have capacities ranging from 750 to 1,250 gallons. A 1000 gallon tank will most likely be required for a typical 3-bedroom home that is smaller than 2500 square feet in size.
How deep in the ground is a septic tank?
Your septic system is normally buried between four inches and four feet underground, depending on the climate.
How to Find Your Septic Tank
Over time, all septic tanks become clogged with sediments and must be pumped out in order to continue functioning properly. Septic tank lids are frequently located at ground level. The majority of the time, they have been buried anywhere between four inches and four feet underground. In the event that you have recently purchased a property and are unsure as to where your septic tank is located, this article will give instructions on how to identify your septic tank.
Noteworthy: While every property is unique, septic tanks are usually typically huge and difficult to build. As a result, and due to the fact that it requires constant pumping, you’re very certain to discover it in a location that can be reached by a huge truck while looking for it.
5 Ways to Find Your Septic Tank
1. Check with the municipal records. The most straightforward method of locating your septic tank is to review the building plans for your home that were approved by the local government. You should have received an application from the business that installed the septic tank, which should contain schematics and specifications that will help you to locate the precise location where the septic tank was installed. 2. Look for highs and lows in your data. The majority of septic tanks are constructed in such a way that they are barely noticeable.
- Almost usually, your septic tank will be constructed near where the main sewage line exits your property.
- Septic tanks are typically positioned between ten and twenty-five feet away from a home’s foundation.
- When you do, that’s when your septic tank comes into play!
- Look for the Lid.
- You will most likely find two polyethylene or fiberglass covers positioned on opposing sides of the perimeter of your septic tank if it was built after 1975 and installed after 1975.
- Those areas should be excavated in order to disclose the lids.

Types of Septic Systems
Septic systems may be found all across the Boise region, and many of them were established some years ago. There are four major components to a septic system: a pipe from the house, the septic tank, the drainfield and the soil that filters the water before it reaches the groundwater table below. After using water in your shower or flushing your toilet, that water flows via your drain pipes and into a septic tank where it may be treated. Within the tank, the waste is separated into three layers: the Scum Layer (on the top), the Water Layer (in the center), and the Sludge Layer (on the bottom) (bottom).
- This is a relatively simple technology that is typically driven by gravity and may be found in rural regions around the Treasure Valley.
- There are two primary types of septic systems: conventional systems and aerobic systems.
- An anaerobic system is one in which the waste is aerated and generally treated with chemicals before being discharged.
- The water discharged from various alternative septic systems may be filtered with sand or other media.
- We provide full-service septic plumbing, which includes the following typical services:
- The following services are available: septic inspection, septic system installation, sewage tank replacement, septic system repairs, and alternative sewage systems.
Every 3 to 4 years, a standard septic tank will need to be cleaned, and annual inspection and maintenance are highly advised. Alternative systems tend to require more maintenance and inspection on a more frequent basis. When your septic tank’s capacity to filter any more solid waste out of the tank has been exhausted, it is necessary to clean your septic tank. A clogged septic tank can cause bad odors to back up into the home and surrounding areas. As the water from the tank spills onto the surrounding area, the land may become marshy.
Septic System Installation
Providing comprehensive plumbing services in Boise, we assist residents with the installation of septic tanks and onsite wastewater disposal systems of various varieties. Septic systems that are traditional in nature are frequently seen, however there are also alternatives such as aerobic systems and other alternativesolutions. Septic tanks are often made of polyethylene, fiberglass, concrete, or steel, and they come in a variety of sizes to accommodate occupants of differing sizes. While some septic tanks may hold up to 2,500 gallons of water, others may only hold 500 gallons.
Consult with a plumber to assist you in selecting and installing the most appropriate septic tank for your needs.
They are bordered by gravel, and the holes in the bottom of the tanks aid in the leaching of wastewater into the soil.
Septic systems make advantage of gravity to move waste through the system as much as they possibly can.
We also install a variety of alternative septic systems, ranging from aerobic to sand trap systems, among others. Depending on where you live in Boise and what type of property you own, these different systems may be the best option for you.
Septic Tank Replacement
These types of waste treatment systems are not complete without the presence of septic tanks. In spite of the fact that they are buried many feet beneath the earth and are constructed of high-quality materials such as steel. Due to regular wear and tear, all septic tanks will eventually need to be replaced at some point. With septic tanks ranging in size from 1,000 to 2500 gallons and lying deep beneath the ground, replacing a septic tank may be a time-consuming and difficult task. The tank must be inspected to see whether it needs to be replaced, and if so, the tank must be dug out and disconnected from the house and leach field.
Septic System Repairs
Septic systems are susceptible to a variety of malfunctions and breakdowns that require the services of a plumber to diagnose and repair the system. There are pipes everywhere throughout this system that can get clogged, break, and/or leak. Septic tanks are frequently in need of replacement, although they can also fail in the inlet and outlet pipes, necessitating repairs rather than replacement. In most cases, leach fields require replacement every twenty years or so. Regular septic inspection and maintenance are suggested in order to avoid costly septic troubles and repairs in the future.
The services offered range from septic inspection to septic repair to the construction of new septic waste systems.

It is critical to appropriately size a septic system’s drain or leach field, as an inadequately sized field might result in serious complications. Waste puddles appearing on your lawn are just one of the issues that might arise, therefore it’s crucial to grasp the fundamentals of how a drain field works. Although you are not required to become an expert in septic systems, a little information may go a long way toward ensuring that your drain field is in good operating condition.
The final depth of a septic system’s drain field is determined by a variety of factors. Drain fields, on the other hand, are typically between 2 and 5 feet deep.
How the Drain Field Works
Solid waste is contained in your septic tank until it is pumped out, which is the final step in the process. The bacteria found in that trash, on the other hand, is far more mobile in nature. As part of the septic process, solid waste is removed from your tank and deposited at the bottom of your tank, while wastewater (together with the bacteria it contains) is discharged from your tank and into your drain field. Once there, the water percolates through the soil and eventually joins the local groundwater supply system.
- In the long run, bacteria are eaten by microbes in the soil.
- This is a significant project that necessitates the establishment of correct soil conditions, including the selection of the appropriate drain fieldsize and depth.
- Typically, a completed bed comprises 12 inches of gravel below the pipe and additional 2 inches of gravel on top of the pipe.
- The end product is a drain field that is approximately 3 to 4 feet deep.
- This type of circumstance might be caused by underground impediments.
- High groundwater tables have the potential to accomplish the same thing, necessitating the installation of a drain field capable of filtering germs at a deeper depth in order to avoid pollution.
Occasionally, this is accomplished by making the drain field shallower, but wider or longer in length. In other cases, a mounded or elevated drain field will be required to prevent flooding.
Drain Field Width and Length
If you have more than one bedroom in your house, your septic system designer will figure out what size drain field you’ll need based on the number of bedrooms you have. In addition, the designer will take into consideration the zoning regulations, soil conditions, and the peculiarities of your lot while designing your home. According to many towns’ regulations, for example, your drain field must be at least a set distance away from your property line. The setbacks from streams, marshes, water supply lines (including local water wells), and other possible barriers are also defined by municipal construction standards.
In addition, pipes are frequently spaced 6 feet apart from one another.
The fact that they are spaced 6 feet apart, on the other hand, provides for the addition of more pipes at a 3-foot spacing if necessary in the future without enlarging the total footprint of the drain field.
It is then decided how this pipe should be laid out in relation to the amount of land available for the leach field to be used.

Amazon is a good illustration of this. Septic tanks are tanks that are built below the surface of the ground. The depth of the tank is determined by a variety of elements that are taken into consideration during the tank’s installation. It is vital to know the depth of a septic tank, especially when access is required for pumping or inspection of the tank.
So, how far down does a septic tank go?
They are generally rectangular in design and measure 5 by 8 feet in dimensions.

When it comes to septic tanks, how deep should they be? Because every condition and location is unique, the depth of a septic tank must be determined based on the specifics of the situation. As a result, before settling on a structure, the designer takes a variety of things into consideration. Assume that the soil type is such that it permits the use of the gravity system to function. Consequently, the septic tank may be built in a convenient location near to the surface. Now, this suggests that the lid can be raised to the level of the grade.
So it allows for the entire effluent to be transported from the septic tank to the distribution section.’ This is the location where they are disseminated.
Depending on the weather conditions, they might be shallower or deeper.
The depth of the drain field is also determined by the level of the tank.
As a result, the top of this septic tank should preferably be directly below grade, with additional soil cover on top. Septic tanks are built substantially deeper in colder climates to accommodate the ice and snow that accumulates.

This is determined by elements such as the kind of soil and geology in which it is constructed. Another consideration is the depth of the sewer pipe leading out from the property. Similarly, in cold areas, the latent heat from the earth, along with the bacterial activity of the sewage, keeps the water from being frozen. Any septic tank should not be buried too deeply underground, since this might cause harm to it and prevent it from performing its intended purpose. Here are a few examples of such elements that have been well explained:
- The presence of a high water table makes a deep septic tank an unwise choice in these circumstances. It is possible that extra soil will be required in order to improve absorption. It results in the formation of a mound, which can function as an above-ground drainfield.
- Type of Soil– The type of soil and the amount of organic matter in the soil influence the depth of the septic tank. High water tables are frequent in clay-rich areas, and they are especially prevalent in the southwestern United States. Professionals can assess the composition of the soil and make recommendations for the depth of the septic tank based on their findings.
- Site Characteristics– As you plan your system, your contractor will be able to evaluate the characteristics of your property. Drainage patterns, water bodies in the area, and slope are all included in this type of study. They can calculate the optimal depth of the septic tank based on these considerations.
- Tank Kind– The type of tank also has an impact on its performance. There are several different types of septic tanks available, some of which may contain up to 2 to 3 feet of earth on top. As a result, if the tanks are placed significantly deeper, the manufacturer’s guarantee will be violated.

A riser should be constructed in septic tanks that are located deep in the ground. Risers are large-diameter tubes that are commonly referred to as ‘wells.’ These are installed directly above the input baffle access point for the septic tank. This is often where the outlet is located. The major reason for installing it is to make it easier for specialists to get to the pump when they arrive to work. Professionals require access to perform services such as baffle repair, inspection, septic tank pumping, cleaning, and other tasks.
This pipe has a big diameter, which allows for convenient access to the tank for pumping and inspection purposes.
How to Find the Septic Tank Lid Deep Below the Surface?
Following these procedures will assist you in determining the depth of your septic tank lid, which will assist you in determining the depth of your septic tank lid:
- You must look for the locations where pipes are exiting your home. This will be located in the basement area. So simply keep an eye on where these pipes are leading. You only have to walk 10 steps from your home. Septic tanks are typically located roughly 10-20 feet from your front door
- You may inspect them with a steel probe if necessary. This should be a maximum of 5 feet in length. Make use of it to drive into the earth. You will be able to feel the location of the septic tank
- Nevertheless, you must use caution so as not to harm the lid. It is possible to puncture it if you are not careful. The first cap is normally found in a grassy area, and if it is punctured, it will cost a lot of money to repair it, so be careful not to puncture it. This is generally located towards the edge of the tank
- The tank’s general width is six feet
- And you may now go back to your front door. You should be able to identify the other cap after only 6 feet of walking. You will receive the discharge cap after taking two steps.
Questions Related to How Deep is a Septic Tank
The lids of septic tanks are often situated around the ground level. The lids are often buried anywhere from 4 inches to 4 feet deep, depending on the situation.
- It is important to understand what happens if a septic tank is installed excessively deep.
It is not suggested to put a septic tank at a location that is too deep. If it is implanted too deeply, it is possible that it will malfunction on a regular basis. It is possible that effluent may backlog on a regular basis and will not naturally flow into the drainfield.
- Whether I am allowed to drive over the septic tank, which is buried underground
No, you should never drive over a septic tank, even if you are aware that it is buried deep down. In a short period of time, driving over the tank will damage its surface, causing it to crack, and cause it to stop operating.
- Anyone who can tell me what the depth of my septic tank is, please.
You can look through your property records to see if there are any details concerning the septic tank’s construction. If you have only recently moved into the neighborhood, you might inquire with the homeowner. If nothing else seems to work, you might enlist the assistance of the specialists who come to examine or pump your water.
- How can I find out if there is a problem with my septic tank, which is buried deep underground?
It is advised that you have your septic tank tested on a regular basis in order to spot problems early on. Furthermore, if you notice any indicators of a septic tank problem, such as a bad odor or sewage backup, it is time to have it checked. If you are unsure about the depth of your septic tank, you can get assistance from a septic tank professional.
They can assist you in discovering the lid of the tank much more quickly, regardless of how deep the lid is hidden. The depth of the septic lid is typically 5 feet, however this might vary depending on the depth of the tank.
