In most cases, septic tank components including the lid, are buried between 4 inches and 4 feet underground. You can use a metal probe to locate its edges and mark the perimeter. If you do not find the lid by probing, shallow excavation with a shovel along the tank’s perimeter should reveal the lid.
- Septic tanks are typically buried only 4 inches to 4 feet from the surface. Putting a source of extreme heat over the top of septic pipes can cause them to melt or burst, which could collapse them inward. Table of Contents
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.
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.
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 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 many lids are on a septic tank?
A septic tank installed before 1975 will have a single 24-inch concrete lid in the center of the rectangle. A two-compartment tank installed after 1975 will have two lids of either fiberglass or polyethylene, centered at opposite ends of the rectangle.
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.
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 much soil should be on top of a septic tank?
the depth of soil backfill over the septic tank lid or septic tank riser lid, ranging from 0″ (which means you should see it) to just a few inches (which means grass may be dead in this area) to 6-12″ or even more.
What is the minimum depth of a sewer line?
Building sewers that connect to private sewage disposal systems shall be a minimum of 36 inches (914 mm) below finished grade at the point of septic tank connection. Building sewers shall be a minimum of 36 inches (914 mm) below grade.
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.
Can I put dirt over my drain field?
Never add additional soil over the drain field unless it is a minimal amount used to restore an area that may have been eroded or pulled up by removing another plant. Try not to be overly zealous when tilling the soil for planting. Remember that the drain lines may be as close as 6 inches from the soil surface.
Why is my grass dying over my drain field?
As temperatures increase, grass draws more moisture from the soil beneath it. The soil above leach lines is shallower than the soil in the rest of the lawn, so it holds less water compared to the rest of the lawn, causing grass directly above the lines to dry out and turn yellow.
How long do drain fields last?
It’s important to consider the life expectancy of a drain-field, too. Under normal conditions and good care, a leach-field will last for 50 years or more. Concrete septic tanks are sturdy and reliable but not indestructible. The biggest risk is exposing the concrete to acidic substances.

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?
Possibly, you are unsure of the exact location of your septic tank on your property and are attempting to find it. Instead of having to go through a lengthy process to discover out where your tank is, there are a number of quick and simple methods available. Let your sewer pipes guide you in the first instance. Most of the time, the tank and drain field will be placed in a line parallel to the sewage line that extends from your property. You may even be able to identify a four-inch sewage line that exits your home in the crawl space or basement of your home.
- Maintain a tight grip on the pipe as it winds its way across the yard, checking every few feet to make sure you are still on track.
- Instead of snooping about in your yard, you can always look up your house’s information in the county records.
- Diagrams with measurements and even the precise location of where the septic tank is located should be included in this document.
- Digging up your lid is another option.
- If your septic tank has a lid, this will tell you how many there are in total.
- The majority of septic tanks are rectangular in shape and measure somewhere in the neighborhood of 5′ x 8′ in dimensions.
- If you are unable to identify your septic tank using a probe, you will need to dig a shallow trench around the perimeter of the tank using a shovel in order to finally discover the lid.
- Initial consideration should be given to visual cues.
- This will immediately inform you where the subterranean tank is located.
- In order to have a decent sense of where the tank is located, look at the plumbing in your building as well as the surrounding environment.
It will be full to just a few inches below the underside of your tank lid when your tank is fully charged to its typical level. Whether the lid is constructed of plastic, fiberglass, or steel, the upper surface of the lid may have some variance.
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
It is possible that understanding how your septic system works may help you manage, maintain, and care for it more effectively. Otherwise, it is simply a large tank buried in the earth that gathers your garbage (which is true, but still). The absence of sewage infrastructure in rural regions is a common occurrence. Because not every rural location is the same, it is not a given that septic systems will be required in your local rural community. In any case, where there are no sewer systems in place, the septic tank serves as a form of wastewater treatment facility.
- In order to prevent your wastewater from leaching into the ground, the tank is designed to be waterproof.
- Solids sink to the bottom of the container, scum rises to the top, and liquids float in the middle of the container between the aforementioned layers of solids and liquids.
- The baffle is constructed in such a way that only liquids may depart through this particular pipe and that no solids can do so.
- Leach or drain fields are what you’re looking at.
- In order to increase the durability and lifespan of these trenches, gravel or crushed stone are used to fill them; however, you may cover those drains with drain field cloth to prevent dirt from getting into your drains.
- After a few days, the wastewater will begin to gently drift over the soil, removing the majority of the hazardous bacteria present in waste before it reaches the groundwater.
A septic service will come out to your home approximately every three years and pump the scum and sludge out of your septic tank, thereby cleaning it and resetting it back to its previous condition.

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
The following are the primary elements that influence the actual depth at which a septic tank is likely to be buried (and, consequently, the depth to which you may have to dig to locate the septic tank) at a specific site:
- 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.

In This Article
- Amount of distance from the home
- Basic safety concerns
- Suggestions for a successful installation
For those who don’t have access to a municipal sewage system, an alternate solution, such as a septic tank and field lines, will be required. The design and operation of these systems are fairly straightforward. When designing a septic system, you must keep in mind the requirements of local construction codes as well as public health concerns.
Depending on where you live, local codes and regulations that specify the distance between the septic tank and the house vary. However, the typical minimum distance is 10 feet between the two structures. Consult your local codes and regulations for a specific answer as to how far your septic tank must be installed from your home. Requirements differ from one location to the next, although the standard minimum distance from the home is 10 feet in most cases. In the case of a private well for drinking water, however, keep in mind that many state departments of health require a minimum distance of 50 feet between a new septic tank and a well.
It is possible that the septic tank will be placed much closer to the structure because it will be easier and require less piping in some cases.
It is ultimately your responsibility as a homeowner to determine where your tank will be installed; therefore, keep a close eye on the situation as your home is being built.
Basic Safety Considerations
If you’re the type of person who prefers to do things on their own, there are certain important measures you should take before starting this endeavor. Before you start digging the hole for the tank, call your local utility providers to find out where the service lines are located. A gas line, water line, phone line, or electrical connection that has been severed is not only potentially dangerous, but it may also be extremely expensive to repair. Once you have finished excavating the hole, proceed with caution.
It’s also important to understand that a concrete septic tank can weigh up to 5 tons.
Make sure the hole is ready when the tank is delivered so that it can be placed directly in the desired location.
Tips for a Successful Installation
Plan ahead of time to get your water supply switched on prior to installing your septic tank. You must fill the tank with water as soon as it is placed in its final position for this to be possible. This has absolutely nothing to do with the septic system itself, but it is a prudent precaution. In the event of a heavy downpour, the groundwater may swell and a septic tank may float out of the ground, even if it has been buried. If this occurs, contact a qualified professional immediately. Repairing any damage done to the lines or to the tank itself, as well as putting the tank back in its original location, may be a costly and time-consuming endeavor.
Initially, you may be confident that you will remember the exact location of the marker when it is time to top up the tank — which is generally every three to five years — but your memory may fade over time.
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 In addition to the information provided above, how deep is a 1000 gallon septic tank?
|Steel Septic Tank Typical Dimensions|
|Steel Septic Tank Size (Gallons Capacity)||Tank Length (Inches)||Tank Depth (Height) (Inches)|
In addition to the aforementioned, may a septic tank be too 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.

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.

When it comes to septic tanks, how deep should they go? Due to the uniqueness of each scenario and place, the depth of a septic tank must be determined by the specifics of each situation and area. As a result, before settling on a structure, the designer examines a variety of aspects. Take for example, assuming that the soil type permits the use of the gravity method. It is possible to construct the septic tank near to the surface in such a condition. So this suggests that the lid may be raised to the level of the top of the grating.
So it allows for the entire effluent to be transported from the septic tank to the distribution system.
They are just around 2 feet deep on average, and they are fairly shallow.
They might also be considerably deeper at times.
The depth of the drain field is also determined by the level in the tank. The top of this septic tank should be directly below grade, with additional soil cover, in order to achieve the best results. Septic tanks are built substantially deeper in colder climates to accommodate the ice and snow.
- 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
If you have any pipes exiting your home, you should look for them. Located at the lower level of the building. Follow the path of the pipes, and you’ll be OK. To get there, you only have to go a few steps. Your septic tank is typically located roughly 10-20 feet from your front entrance; you can investigate with a steel probe. 5 feet should be the perfect length. It may be used to drive into the ground. When you walk around the septic tank, you will obtain a sense of its position; however, you must take care not to harm the lid.
A punctured cap will necessitate an expensive replacement; the first cap will normally be found in a grassy location; the second cap will be found in a shady region.
You should be able to discover the other cap if you travel only 6 feet more.
- 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.

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.
How Your Septic System Works
Underground wastewater treatment facilities, known as septic systems, are often employed in rural regions where there are no centralized sewage lines. They clean wastewater from residential plumbing, such as that produced by bathrooms, kitchen drains, and laundry, by combining natural processes with well-established technology. A conventional septic system is comprised of two components: a septic tank and a drainfield, often known as a soil absorption field. It is the septic tank’s job to decompose organic matter and to remove floatable stuff (such as oils and grease) and solids from wastewater.
Alternate treatment systems rely on pumps or gravity to assist septic tank effluent in trickling through a variety of media such as sand, organic matter (e.g., peat and sawdust), constructed wetlands, or other media to remove or neutralize pollutants such as pathogens that cause disease, nitrogen, phosphorus, and other contaminants.
Specifically, this is how a typical conventional septic system works:
- All of the water that leaves your home drains down a single main drainage pipe and into a septic tank. An underground, water-tight container, often composed of concrete, fiberglass, or polyethylene, serves as a septic system’s holding tank. Its function is to retain wastewater for a long enough period of time to allow particles to sink to the bottom and form sludge, while oil and grease float to the surface and produce scum. Sludge and scum are prevented from exiting the tank and moving into the drainfield region by compartments and a T-shaped outlet. After that, the liquid wastewater (effluent) exits the tank and flows into the drainfield. The drainfield is a shallow, covered hole dug in unsaturated soil that serves as a drainage system. Porous surfaces are used to release pretreated wastewater because they allow the wastewater to pass through the soil and into the groundwater. In the process of percolating through the soil, wastewater is accepted, treated, and dispersed by the soil, finally discharging into groundwater. Finally, if the drainfield becomes overburdened with too much liquid, it can flood, causing sewage to flow to the ground surface or resulting in toilet backups and sink backups. Finally, wastewater percolates into the soil, where it is naturally removed of harmful coliform bacteria, viruses, and nutrients. Coliform bacteria are a kind of bacteria that may be found in the intestines of humans and other warm-blooded animals, with humans being the most common host. As a result of human fecal contamination, it is a sign of this.
The Guadalupe-Blanco River Authority has built an animated, interactive model of how a residential septic system works, which you can view here.
Do you have a septic system?
It’s possible that you’re already aware that you have a septic system. If you are not sure, here are some tell-tale symptoms that you most likely are:
- You make use of well water. In your home, the water pipe that brings water into the house does not have a meter. In the case of a water bill or a property tax bill, you will see “$0.00 Sewer Amount Charged.” It is possible that your neighbors have a septic system
How to find your septic system
You can locate your septic system once you have confirmed that you have one by following these steps:
- The following are some methods for determining whether or not your home has a septic system.
Failure symptoms: Mind the signs!
A bad odor is not necessarily the first indicator of a septic system that is failing to work properly. Any of the following signs should prompt you to seek expert assistance:
- Water backing up into the drains of homes and businesses
- It is especially noticeable in dry weather that the drainfield grass is bright green and spongy. The presence of standing water or muddy soil near your septic system or in your basement
- A strong stench emanating from the area surrounding the septic tank and drainfield
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.
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.
- Get in touch with the pros.
- Lifting concrete lids will necessitate the use of specialized equipment.
- A fall into an unprotected septic tank has the potential to be lethal.
- Produce your own diagram of your yard, which you may file away with your other important house paperwork.
That’s all there is to it! If you’ve been wondering where your septic tank is, you now have five alternatives to choose from, which should make finding it easier than ever. To book a plumbing service in Bastrop County, please contact us now!

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?
In order to maintain a healthy pH balance in your system and to encourage better sewage digestion, we recommend that you flush one cup of baking soda down the toilet once a week.
Q. What do you do with my septage once it is removed from my tank?
In order to maintain a healthy pH balance in your system and to encourage better sewage digestion, we recommend that you flush one cup of baking soda down the toilet every week.
Q. How do I find my septic tank?
A. Here are a few options for you to consider. Septic tanks are typically rectangular in design, measuring around 4 by 8 feet.
- You’ve probably come across a rectangular stretch of ground where the snow melts first in the winter and the grass burns first in the summer. An underground septic tank can be submerged to any depth between flush with the surface of the earth and more than 6 feet. When you look down in your basement, you can see where the sewer pipe exits through a hole in the wall. Take note of how far the pipe extends below the top of the foundation and whether or not it exits through the wall directly. When looking from the outside of the house, this will provide you with an approximate orientation for the pipe leading to the tank. To determine how far the tank is below grade, measure down from the top of the foundation wall to the ground’s surface and subtract that measurement from the inside measurement (also subtract another 6 because the top of the sewer pipe is usually 6 down on either side or end of the tank) to get a rough estimate of how far the tank is below grade. You can probe for the tank top using a steel bar or rod that you push into the earth. Keep in mind that you are searching for a flat rectangular space around 4 x 8 inches below the surface of the earth
- Many septic systems are not gravity systems and require pumping to function properly. Excavation around your septic tank and/or pump tank should always be done with extreme caution since electrical lines can be hidden underground and are not usually marked, posing a possible electrical danger. Never fear if you can’t identify your septic tank
- We have specialized equipment that can help us locate the tank if necessary
- Just give us a call.
Q. Can my septic tank baffles be repaired?
A. Yes, we replace a large number of deteriorating concrete baffles with PVC baffles each year.
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.
Q. Do you have any other tips you can give me?
A. Without a doubt! View the State of Maine’s Ten Tips for Maintaining Your Septic System for more information.
HOW TO SAFELY ABANDON AN OLD SEPTIC TANK ON YOUR PROPERTY
If you’ve recently purchased an older house, it’s possible that a septic tank is located on the property. This is true even if your home is currently linked to the municipal water and sewer systems. A prior owner may have abandoned the ancient septic system and connected to the city sewage system when it became accessible at some time in the past. Despite the fact that there are regulations in place today for properly abandoning a septic tank, it was common practice years ago to simply leave the tanks in place and forget about them.
- The old tank may either be demolished or filled with water to solve the problem.
- It is possible that permits and inspections will be required.
- They are dangerous because curious children may pry open the lid and fall into the container.
- Falls into a septic tank can be lethal owing to the toxicity of the contents and the fact that concrete can collapse on top of you while falling into a tank.
- Eventually, this approach was phased out due to the fact that the steel would corrode and leave the tank susceptible to collapse.
- When it comes to ancient septic tanks, they are similar to little caves with a lid that might collapse at any time.
- The old tank is crushed and buried, or it is removed from the site.
If it is built of steel, it will very certainly be crushed and buried in its current location.
After that, the tank can be completely filled with sand, gravel, or any other form of rubble and buried.
Tanks can either be entirely dismantled or destroyed and buried in their original location.
The abandonment has been documented and plotted on a map.
It’s possible that you’ll forget about the tank once it’s been abandoned.
As a result, you might wish to sketch a map of the area where the old tank used to stand.
If you can demonstrate that an old septic tank was properly decommissioned, you may be able to increase the value of your property, and the new owners will enjoy knowing that large chunks of concrete are buried underground before they start digging in the yard to put something in it.
It may take some detective work to discover about the history of your land and what may be lying beneath the surface of the earth.
Upon discovering an old septic tank on your property that is no longer in service, contact Total Enviro Services for propertank abandonment procedures that meet with local standards and protect your family, pets, and farm animals from harm or death.
How Low Can You Go?
Septic tanks may be present on the property if you’ve recently purchased an older house. This is true even if your home is currently linked to the municipal water and wastewater system. It’s possible that a prior owner abandoned the ancient septic system and connected to the city sewer system when it became accessible at some time in the past. Despite the fact that there are standards in place now for properly leaving a septic tank, it was formerly normal practice to simply leave the tanks in place and forget about them years ago.
- The old tank may either be demolished or filled with water as a solution.
- You may be required to get permits and undergo inspections.
- They are dangerous because curious children may attempt to pry open the lid and fall within.
- It is possible to die by falling into a septic tank because of the poisonous nature of its contents and because of the possibility that concrete will fall on you.
- Eventually, this approach was phased out due to the fact that the steel would corrode and leave the tank liable to collapse.
- Septic tanks that are more than 20 years old are like miniature caves that might collapse at any time.
- Crushed and buried or removed, depending on the situation, the old tank If you have an outdated septic tank, your contractor will determine the most efficient approach to remove it.
Alternatively, if the tank is built of concrete, the bottom or sides may be broken apart so that the tank can no longer retain water, and the tank can then be filled with sand, gravel, or some other sort of rubble and buried beneath the ground.
There are two options for removing tanks: either they are totally removed or destroyed and buried in place.
Documentation and mapping of the abandonment Because they are underground, septic tanks can be difficult to locate even when they are presently in use.
Those who purchase the property in the future will be completely unaware of its presence.
In addition, your city or county will have the permit and inspection records that indicate the job was done in accordance with code requirements.
Please keep in mind that septic systems are not designed to survive forever, and it is probable that you have more than one abandoned tank on your property.
Upon discovering an old septic tank on your property that is no longer in use, contact Total Enviro Services for propertank abandonment methods that meet with local standards and protect your family, pets, and farm animals safe from harm or death throughout the process.
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 National Precast Concrete Association (NPCA) maintains an online Best Practices Manual that may be accessed from any computer. It typically encompasses all parts of a precast process, from the selection of materials through the production of a watertight, structurally sound product; storage; transportation to an installation site; and the procedures for installing the product. Anybody who works with precast concrete products will find it to be an invaluable resource. According to the guideline, a septic tank must be built to endure a wide range of loading situations during the manufacturing, installation, testing, and operation phases of the tank.
- If these calculations are to be completed by a competent professional engineer, they should be tested according to ASTM C1227.
- It is available in English and Spanish.
- Consequently, the rules come into play by stating the pounds per square foot of soil backfill that will be placed over the tank’s surface.
- Consider approaches to minimize permeability, enhance durability, and boost strength for consideration by the readers of this article.
- It also emphasizes the importance of regular water-cement mix ratios in order to assure the strength of the concrete.
- Because of this, it is vital that the product can stand empty, then endure the soilpressures applied vertically and laterally, as well as withstand temperature variations in my region of the world.
It is possible that failing to follow these recommendations could result in the tank breaking during installation or will cause difficulties with watertightness down the road.
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.
