How Deep Should A Septic Tank Be Buried? (Solution)

The general rule of thumb is that most septic tanks can be buried anywhere from four inches to four feet underground.

What is the standard depth of a septic tank?

Tanks are typically buried 4 inches to 4 feet deep depending on local site conditions, shape, slope, and other factors. Here is the basic math for computing septic tank capacity (volume) in gallons.

How much dirt should be in the top of a septic tank?

Septic systems are generally planned to have anywhere from 6 inches to 30 inches of soil on top of them.

Can a septic tank be too deep?

Keep septic tanks high: we don’t put the septic tank any deeper than necessary, since we are usually moving effluent from the septic tank to the drainfield also by gravity. Plumbers usually install sewer lines to slope down from inlet to outlet, at 1/8″ per foot to 1/4″ per foot of linear run of the waste pipe.

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.

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 often does a 1000 gallon septic tank need to be pumped?

For example, a 1,000 gallon septic tank, which is used by two people, should be pumped every 5.9 years. If there are eight people using a 1,000-gallon septic tank, it should be pumped every year.

What are the signs that your septic tank is full?

Here are some of the most common warning signs that you have a full septic tank:

  • Your Drains Are Taking Forever.
  • Standing Water Over Your Septic Tank.
  • Bad Smells Coming From Your Yard.
  • You Hear Gurgling Water.
  • You Have A Sewage Backup.
  • How often should you empty your septic tank?

Why is the ground soft around my septic tank?

The presence of healthy, lushly growing plants around your septic tank or along the route of your drainage lines indicates wet areas, as does a spongy or damp feel to the ground. Excess moisture might mean that your tank is full or that your drainage pipes are damaged.

Can I plant a garden on my septic field?

Planting over a septic leach field (drain field) is possible if it is done with care. Growing shallow-rooted plants over the drainage area is recommended because they help remove excess moisture and nutrients from the soil and reduce erosion.

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 deep is the septic tank outlet pipe?

After the solids settle out, effluent leaves the septic tank through the outlet pipe and flows to the drain field. The outlet pipe should be approximately 3 inches below the inlet pipe.

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.

How much does it cost to pump a septic tank?

How much does it cost to pump out a septic tank? The average cost is $300, but can run up to $500, depending on your location. The tank should be pumped out 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.

How Deep Should WePutthe Septic Tank at Original Installation?

Septic tanks may be built almost anywhere in the soil, regardless of its depth. When operating in a freezing climate, even in uninhabited homes, it is unlikely that the septic tank serving an occupied home or even an unoccupied one will freeze. This is due in part to latent heat received by the septic tank’s bottom from earth, in part to heat generated by bacteria in the septic tank, and in part to warm wastewater entering from a building served by the septic system, and in part to warm wastewater entering from the building served by the septic system.

You’ll kill the bacteria, damage the drainfield, and taint the surrounding ecosystem as a result of this.

Factors Determining Septic Tank Depth

Installation of septic tanks is possible at almost any depth in the ground. When operating in a freezing climate, even in uninhabited homes, it is unlikely that the septic tank serving an occupied home or even an unoccupied one will freeze. This is due in part to latent heat received by the septic tank’s bottom from earth, in part to heat generated by bacteria in the septic tank, and in part to warm wastewater entering from a building served by that septic system, and in part to warm wastewater entering from the building served by the septic system.

Besides contaminating the surrounding environment, you’ll also kill the microorganisms and degrade the drainfield.

  • The depth to which the lowest sewage line departs the structure that the septic tank serves is referred to as the sewer line depth. Given that we often rely on gravity to transport sewage from a building to a septic tank, the tank will be lower than the waste line that exits the building that it serves. a spot where the contractor discovered site characteristics suited for burying a septic tank because of its form, rocks, and impediments If a location has bedrock or huge rocks that are near to the surface, the tank may be relocated
  • The greater the distance between the tank and the structure, and the greater the depth of the tank if the system relies on gravity to carry sewage, the deeper the tank will be. We don’t place septic tanks any deeper than they need to be since we are normally transporting effluent from the septic tank to the drainfield by gravity as well as by pumping it out. 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. In order to avoid septic drainfield burial at an excessive depth, we must ensure that there is sufficient air in the soil, since the absence of oxygen deep in the soil will inhibit certain desired bacterial action (the aerobic bacteria) that is required to break down and process sewage. It is certainly possible to locate and position the septic tank anywhere, including uphill from the building, if a sewer ejector pump or grinder pump system is utilized to transport sewage from a structure to an underground storage tank. If a sewage effluent pump is used to transport septic effluent from the septic tank to the drainfield, we may, of course, locate the tank “downhill” from the drainfield as well
  • But, if a sewage effluent pump is not utilized, we cannot. Growing grass: If the septic tank is just 2 or 3 inches below the surface of the earth, you might as well have left the top of the tank visible, because grass will not grow in such thin soil as you would expect. Adding 6″ to 12″ of backfill may be sufficient to allow grass to grow over the septic system
  • However, this is a purely aesthetic issue and does not affect the system’s functionality. See SEPTIC SYSTEMS, OVERHAULED PLANTS
  • Recommendations from the manufacturer: Some modern septic treatment system designs need the use of a skilled system operator to perform highly specified inspection and maintenance intervals. According to the information provided atBAT MEDIA SEPTIC PLANTS, BAT septic systems (biologically accelerated treatment) are maintained or examined at 6-month intervals, among other things. According to the maker of that technology (Jet Inc.), it is extremely critical that the finishing grade slope away from the facility when completed. In addition, the grade must be at least 1″ below the bottom of the access covers to be considered. (Jet retired in 2016)

A service riser should be put in deep septic tanks to provide access to the tank. Plungers are large-diameter “wells” that are installed over the entrance and/or outlet ports of a septic tank in order to provide simple access for tank pumping, inspection, and baffle repair. Plungers are also used for septic tank pumping, inspection, and baffle repair. If the septic tank is sunk more than a few inches below the surface of the earth, good practice calls for the installation of a septic riser, which is a high diameter pipe that allows for easy access to the septic tank for inspection and cleaning.

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 Also, what is the depth of a 1000 gallon septic tank?

Is it possible for a septic tank to be too deep in this case? 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.

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.
  • Septic tanks are built substantially deeper in colder climates to accommodate the ice and snow that accumulates.

CALL 855.925.0760 FOR SEPTIC SERVICES

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.

  • Drain Field Operation

  • Drain Field Width and Length
  • How the Drain Field Works

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.

Tip

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.

Septic Tank Depth

Trevor, The amount of heat created by biological activity in a septic tank is unknown to me, but I think that a tank that is actively functioning will generate more heat than a tank that is in “holiday” mode. The overall amount of warm water and “food” placed into the tank may not be very much if you have a two-person family like mine, hence the tank may not contain 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.

  • If the frost line penetration corresponds to the tank height, the total temperature in the tank may be able to reach freezing temperatures at some point.
  • Even though the ground temperature 6′ down may only be 35-40 degrees Fahrenheit in the middle of winter, that should be sufficient to keep an idle tank from freezing.
  • When flowing into a 1500 gallon tank, the amount of heat provided by a warm shower is not very significant.
  • Ice spreads in all directions, which may put pressure on the tank’s walls as a result of the expansion.
  • Because the tank I have is relatively thin in comparison to the ones I remember from decades ago, I’m hoping that someone out there can offer anecdotal evidence regarding how robust the new thin tanks are.
  • When the ice penetrated deep enough into the earth to freeze all the water pouring from the house during a particularly harsh winter, my next-door neighbor was forced to rescue a friend.
  • Oddly enough, I don’t recollect my neighbor mentioning whether or not the output pipe had frozen as well.
  • The hypothesized explanation is that automobiles push ice into the ground while on the road.
  • I believe that driving a car across the tank top would be a more serious problem.
  • Snow provides some insulating properties, however it appears that windy circumstances may cause the snow to become thin, as your sand has done in your case.

Perhaps Michael can contribute some real-world insights concerning the inlet and outflow danger in your region based on his own experiences. Although I live in a 6B zone, temperatures can drop below -20 degrees Fahrenheit at times.

Receive articles, stories, and videos about trucks delivered directly to your email! Now is the time to sign up. Trucks+ Receive Notifications The topic of whether or not there are guidelines for septic tank burial levels was put to me a few months ago and it seemed easy enough. Of course, there are standards, and they are based on the strength of the materials used in the tank’s construction as well as the materials’ capacity to bear all of the forces acting vertically and laterally on the tank where it is located.

As I continued to think about the subject, I began to think about all of the different types of tanks and all of the different manufacturers, and I realized that I should take a closer look at the specifications as well.

In the codes

In the first, it was specified that “tank components such as fitting, riser, and apertures (openings) must: Be capable of carrying long-term vertical stresses appropriate for the conditions in which the tank will be positioned.” Among these loads are: saturated soil load (based on 130 pounds per cubic foot); being capable of withstanding a lateral load for the conditions in which it will be installed; being resistant to corrosion and degradation caused by sewage or sewage gases (including risers and maintenance hole covers) with proper maintenance and venting; and being structurally capable of withstanding exposure and stresses caused by freezing conditions.” Tanks must be “structurally built to sustain all predicted earth or other loads,” according to the second code of practice.

When constructed as described above, the tank is capable of supporting an earth load of 300 pounds per square foot, and if the top of the tank is more than 2 feet below finish grade, the septic tank and its cover are capable of supporting an additional earth load of 150 pounds per square foot for each foot of additional cover.” Several other parts of both codes stipulate that prefabricatedconcrete septic tanks must fulfill the requirements of the “Standard Specification for PrecastConcrete Septic Tanks C1227-03,” which was produced by the American Society for Testing and Materials (ASTM).

The International Association of Plumbing and Mechanical Officials (IAMPO) has released “Material and Property Standards for Prefabricated Septic Tanks, IAMPO PS-1 2004,” which specifies the materials and properties of prefabricated fiberglass and polyethylene tanks.

If you go directly to the publishers, these standards may have received additional updates and revisions after the date of incorporation; copies of the standards are also available for a price if you order them straight from them.

Precast concrete manual

The first one said that “tanks, fittings, risers, and apertures(openings) must: be capable of carrying long-term vertical stresses for the conditions in which the tank will be positioned.” The second one stated that These loads include, but are not limited to, saturated soil load based on 130 pounds per cubic foot; be capable of withstanding a lateral load for the conditions in which the tank will be placed; be subject to corrosion and degradation from sewage or sewage gases, including risers and maintenance hole covers; and be structurally capable of withstanding exposure and stresses from freezing conditions.” Tanks must be “structurally built to sustain any expected earth or other loads,” according to the second code.

When constructed as described above, the tank is capable of supporting an earth load of 300 pounds per square foot, and if the top of the tank is more than 2 feet below finish grade, the septic tank and its cover are capable of supporting an additional earth load of 150 pounds per square foot for each foot of cover above the finished grade.

Materials and property standards for prefabricated fiberglass and polyethylene septic tanks, established by the International Association of Plumbing and Mechanical Officials, must be met by prefabricated fiberglass and polyethylene septic tanks.

According to their state office and the library system, copies of these standards that have been included by reference into the code can be received at no cost.

Copies of the standards are also available for purchase.

Other tank materials

With regard to fiberglass and polyethylene tanks, the manufacturer’s information sheet on their goods will include information on the maximum depth of burying required to avoid deformation. Some of the tanks I have been working with have a maximum bury of 30 inches, which is a standard amount. Additionally, because these tanks are often lighter than concrete (which is one of its selling advantages for difficult-to-reach regions), greater attention must be paid to buoyancy issues during and after installation.

Because of this, each manufacturer has particular backfill instructions and regulations to fill the tank “as you go” throughout the installation process in order to prevent lateral tensions.

How to Run a Septic Tank Line From Your House

A septic system is made up of two lengths of pipe that are connected together. Initially, it runs from the house, where the system services are located, to a tank, where the waste is separated and solids settle out. The second section runs from the tank to the drainage field, where fluids from the tank are dispersed into the earth underneath the tank.

The process of installing the first run of pipe is quite similar to that of installing a traditional sewage line. It is necessary to maintain a downhill slope to the storage tank.

Locating the Septic Tank

The tank serves as the nerve center of the septic system. It is required to be situated between the residence and the drainage field. Each and every septic installation must begin with a soil test, and depending on the results, soil conditions may necessitate the placement of the tank in a less-than-ideal site for digging sewer lines. Also required are minimum setback distances from property borders, functioning wells, surface water and other obstructions to provide a safe working environment.

Tank Depth

A standard septic tank has a 4-inch intake at the top, which is positioned towards the bottom. Ideally, a 1/4-inch-per-foot slope toward the pipe from the house should be maintained by the pipe connecting to it. To put it another way, for every 10 feet of distance between a tank and a home, the inlet must be 2 1/2 inches lower than where the pipe departs the house at its lowest point. The pipe usually exits at ground level, although it may need to pass beneath a foundation footing or concrete pad in rare cases.

Digging the Trench

The trench for the septic pipe should be dug before the hole for the tank since you will need a backhoe to complete the work and the tank will get in your way if it is already in the ground. To allow rainfall to drain properly, the pipe should be placed on a 2- or 3-inch bed of drain rock, so remember to account for this extra depth when digging. It is normal to use a four-inch pipe, and it should be installed far enough down to link with the main soil stack, which is a three-inch pipe that runs vertically past the main bathroom and through the roof of the home.

Precautions

Since you’ll need a backhoe for the task and the tank will get in the way of your work if it’s already in the ground, it’s usually best to build the trench for the septic line before digging a hole for it. Take into consideration that the pipe should be placed on a 2- or 3-inch layer of drain rock in order to allow rainfall to drain properly. It is typical to use a four-inch pipe, and it should be installed far enough underground to link with the main soil stack, which is a three-inch pipe that runs vertically past the main bathroom and through the roof of your home.

The following are some of the most frequently asked questions about septic tanks. If you don’t find your question answered on this page, please contact us and we’ll be happy to assist you further.

Q. How often should I have my septic tank serviced?

It is recommended that you replace your A/C system once every two to five years, depending on how often you use it and how many people are utilizing the system.

Q. Do you have to drive on my lawn to service my septic tank?

A.

No, it is not our policy. We carry roughly two hundred feet of hose, which is generally more than enough for most residential applications. We may bring additional hose if necessary if we are given advance notice.

Q. Is it O.K. to use drain cleaners with a septic system?

A. Avoid using drain cleaners and other chemicals whenever possible. They have the potential to disrupt the naturally existing biological processes in the septic tank and leaching region of the property. One gallon of some hazardous compounds can damage twenty-two million gallons of ground water, according to the Environmental Protection Agency.

Q. Do I need to use additives in my septic system?

Q. Are septic tank filters any good, don�t they plug up frequently?

An absolutely necessary addition to your septic tank is the installation of a Zabel filter by our team. These filters help to keep particles down to one-sixteenth of an inch in the septic tank by trapping about 80% more solids. Over the years, we’ve discovered that the Zabel filters appear to be the most effective. It is just necessary to remove the clogged filter, wash it well and replace it when the problem arises. In most cases, filter maintenance is performed at the same time as septic tank maintenance.

Q. I hate digging up my septic tank and having the mess in my lawn every three years or so.What can we do to save all that mess?

The installation of a riser above the service cover is recommended. It is recommended that each of the access covers for the filter and pump be equipped with a riser as well. Risers are now required under the State of Maine’s Subsurface Rules. We choose to use Fralo risers because they may be erected in sloping grass areas and because they are simple to install flush with the ground surface.

  • A 2″ PVC output with a threaded connector for improved connecting of pressure lines to the pump and septic field Limited guarantee on materials and workmanship for a period of 20 years

What are Septic Tanks?

Septic tanks are two-compartment wastewater treatment devices that are located underground. In rural areas where there is no public sewer system, these buildings are commonly utilized to collect and treat waste. Septic tanks are often used in conjunction with a septic or drain field system, which treats home wastewater by using soil drainage.

Sewage holding tanks, on the other hand, are single-compartment tanks that collect and store wastewater from households and businesses. When the tanks are completely full, a vacuum truck comes to empty them.

How Do Septic Tanks Work?

Septic tanks function in the following ways:

  • The intake pipe is responsible for directing wastewater from your house into the septic tank. Using the working chamber, it is possible to separate heavy materials from lighter fats, oils, and greases. Transfer of the liquid, also known as effluent, from a baffle to the pump chamber. The wastewater is transported to a septic field by a siphon assembly or an electric pump. The septic field is generally comprised of an arrangement of perforated pipe contained within a trench. In the process of draining through the soil, wastewater is accepted, treated, and dispersed by the soil, finally discharging into groundwater.

It is necessary to consider site considerations such as altitudes, lot size, soil types, and municipal regulations while designing a septic field. So, qualified installers and professional designers are typically tasked with the task of creating septic system designs.

What Size Septic Tank Do I Need?

The size of your septic tank is determined by a number of different factors. The minimal operating capacity necessary, as defined by the Alberta Private Sewage System Standard of Practice, is provided by the following computation. However, some fixtures, such as trash disposal systems and hot tubs, should be given additional care in this regard. In addition, the minimum sludge capacity must be taken into mind as well. Number of bedrooms multiplied by 1.5 people each bedroom multiplied by 75 gallons per person per bedroom Consider the following example: according to the calculations above, a three-bedroom residence must have a working capacity of about 337 gallons, which can be attained with our P1220 septic tank.

Which Type of Septic Tank is Best? Concrete vs. Plastic Septic Tanks

Concrete septic tanks have various advantages over plastic septic tanks, including the following:

  • A concrete septic tank weighs substantially more than a plastic tank of the same size. Concrete tanks will not float as a consequence
  • The long-term performance of a plastic tank is dependent on the care used during installation to ensure that the tank’s support structure is achieved. Concrete septic tanks, on the other hand, have structural stability built in from the beginning. Plastic tanks are more prone to damage, and additional precautions must be taken to ensure that they do not develop punctures during the backfilling process to prevent this. Constructed concrete septic tanks, on the other hand, are extremely long-lasting and sturdy

How Deep Do I Bury My Septic Tank?

Site considerations such as the frost line have a considerable influence on the depth of a septic tank’s underground burial. As a result, burial depths are typically between 2′ and 10′ below the surface of the soil. Our 1220P and 1518P models offer the highest burial depth ratings in the underground concrete tank industry, and they are available in two sizes. Please get in touch with us if you require any information on sewage systems in Alberta or if you would want to be referred to a licensed installer.

Can My Septic System Freeze? – Miller Septic Services

Despite the fact that the majority of sewage systems are buried deep enough underground to avoid freezing, there are several components of a septic system that can freeze, such as:

  • The septic tank
  • The pipes that connect your home to the septic tank
  • The pipes that connect your septic tank to the drainfield
  • It is the drainfield.

What Causes A Septic System to Freeze?

When the septic line isn’t buried deep enough in the earth to avoid freezing, or when compacted dirt is covering the septic line, your system is at risk of bursting and freezing. Those pipes that run from your home to your septic tank are the most prone to become clogged. The source of the problem might be a leak in one of your water fixtures in your house, such as faucets or toilets. The leak allows for a sluggish, continuous flow of water through pipes, which causes the pipes to freeze and get clogged.

When the weather is exceptionally cold, make sure to run your system many times a day, especially if the water temperature is warmer, to keep the water flowing (do not OVERUSE and place unnecessary stress on the system though).

How Do I Know If My Septic System is Frozen?

If you experience any of the following difficulties with your day-to-day plumbing, your system may be frozen:

  • Toilet is not flushing properly
  • There is a blockage in the drains of the sinks, showers, and baths.

How Do I Avoid a Frozen Septic System?

Try any of these suggestions to keep your system from being frozen:

  • Before winter sets in, cover the space above your pipes, tank, and soil treatment system with mulch or other materials such as hay or leaves to keep the cold air out. Plan to run a hot water laundry load or take a warm shower every day to stagger your hot water consumption. Allowing anything or anybody to walk or drive over your system might cause compacted snow and dirt to force frost deeper into the ground at a quicker pace, causing it to fail sooner. Pipes should be insulated. In the event that you have an outfall or discharge, try to keep it free of obstructions in order to ensure that any effluent water generated has the best opportunity of getting away efficiently.

What Should I Do If I Think My Septic System is Frozen?

We do not advocate that you attempt to unfreeze your septic system on your own. A professional septic service such as Miller Septic can inspect your system and determine the source of the problem.

The use of specialized cameras allows us to check lines and identify the source of the problem. To securely clear frozen pipes, we employ professional-grade equipment such as hydro jetters.
