How Deep Can You Dig For Septic Tank? (Best solution)

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

How deep underground should a septic tank be?

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.

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 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.

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.

How big is a typical septic drain field?

A typical septic drainfield trench is 18 to 30 inches in depth, with a maximum soil cover over the disposal field of 36″; or per the USDA, 2 feet to 5 feet in depth.

Can you have a septic tank without a leach field?

The waste from most septic tanks flows to a soakaway system or a drainage field. If your septic tank doesn’t have a drainage field or soakaway system, the waste water will instead flow through a sealed pipe and empty straight into a ditch or a local water course.

What is the most common cause of septic system failure?

Most septic systems fail because of inappropriate design or poor maintenance. Some soil-based systems (those with a drain field) are installed at sites with inadequate or inappropriate soils, excessive slopes, or high ground water tables.

What is the alternative to a septic tank?

Mound systems work well as alternatives to septic tanks when the soil around your home or building is too dense or too shallow or when the water table is too high. Although they are more expensive and require more maintenance than conventional systems, mound systems are a common alternative.

What will ruin a septic system?

Any paper products like tissues, paper towels, tampons, or sanitary products, even some heavier toilet paper, will clog your system if you flush enough of it. Wet wipes are another product that you should never flush into a septic system.

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 Should a Septic Leach Field Be?

Photograph courtesy of Valerie Loiseleux/E+/Getty Images.

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.

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

A septic system is constructed from two lengths of pipe. Initially, it runs from the home, where the system services are located, to a holding 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 under the surface. It is quite similar to installing a traditional sewage line when you are putting in your first run of pipe. Maintaining a downhill slope towards the tank is essential.

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

Local building and health agencies will demand permits for a septic tank installation. You will also be required to submit a design plan before the permits will be provided, so prepare ahead of time. This layout should be developed in collaboration with a local builder who is familiar with the unique characteristics of the topography in your neighborhood. Stay away from planting trees or plants near the tank, drainage field, or any of the pipe systems. They will be drawn to the pipes in their hunt for nutrition, and their roots will be able to successfully block them.

Removal may be both expensive and time-consuming.

When Digging a Pond, How Far From a Septic Field Line Should You Dig?

The installation of a pond in close proximity to a septic system requires some understanding of how septic systems operate as well as your local rules on setbacks. However, the bacteria and nutrients from a drain field can have an impact on even an ornamental garden pond, especially one that is located downstream from the septic system.

According to the construction requirements in your area, a pond and the leach lines of your septic system should be separated by 50 to 100 feet, depending on the size of the pond.

Septic System Setbacks

Setbacks for septic systems are strictly enforced according to industry standards. Your local building permit office is likely to provide a form that not only describes how to apply for a septic system permit, but also specifies the minimum setbacks that must be adhered to. In general, leach fields must be located at least 100 feet away from streams, rivers, water supply wells, seas, lakes, or reservoirs, as well as other bodies of water. In accordance with local construction rules, a pond may be deemed a man-made reservoir for the purposes of water storage.

How a Septic System Works

Sewage treatment systems are comprised of two parts: an underground tank, in which the waste water from your house is divided into solids and fats; and a leach or drain field, in which the waste water gradually seeps into the soil or evaporates. On order to prevent the waste water from reaching the subterranean water that supplies your well, the leach field is constructed in soils that will gently absorb and filter the water, rendering it safe before it reaches the underground water that supplies your well.

How a Septic System Affects a Pond

In contrast to how well your septic system filters and cleans the waste water from your house, having a pond too close to the leach fields can have negative effects on the ecosystem of the pond itself. Extra nitrogen and phosphorus leaching into the pond from the leach field might result in a proliferation of aquatic plants and algae in the water body. It makes no difference whether your pond is meant to support fish farming or koi, the septic system can have an adverse effect on the fish, either by killing them or infecting them with hazardous germs.

Protecting the Septic System

Septic systems are typically low-maintenance systems for properly processing sewage from your house, but there are steps you can do to keep them in good working order as well. It is beneficial to plant an open meadow over a leach field because it encourages waste water to evaporate as the plants absorb surplus nutrients, which prevents them from moving through the soil to neighboring ground water or rivers. Keeping heavy equipment and trucks out of the system helps to maintain the leach field and save costly repairs in the long run.

How to Locate Your Septic Tank

It may seem impossible to imagine that one of the largest and most visible elements of your whole plumbing system is also one of the most difficult to locate, but when your property is served by a septic system, this is perfectly true. A strong explanation for this is because septic tanks are huge, unattractive, stink horrible and give off an unwarranted impression of dirt. Not only does burying them underground assist to prevent them from harm, but it also provides you with additional useable space on your property and conceals what would otherwise be a blight on your landscape.

This site is dedicated to assisting you in locating your septic system without the need for any time-consuming digging.

How To Find A Septic Tank: Step By Step

It is critical to maintain the health of your septic tank since it is responsible for securely storing and handling the wastewater that drains from your house. It is necessary to pump your septic tank once every 1-3 years, depending on the number of people living in your household and the size of your tank, in order to avoid septic tank repairs or early failure, which means you must be familiar with the location of your tank. It’s not often simple to identify your septic tank, and many plumbers charge extra for this service, which is especially true if your tank’s lid is buried beneath.

1. Gather Some Helpful Tools

It is critical to maintain the health of your septic tank system since it is responsible for securely storing and controlling the wastewater that exits your house. It is necessary to pump your septic tank once every 1-3 years, depending on the number of people living in your household and the size of your tank, in order to avoid septic tank repairs or early failure, which means you must be familiar with its location. Unfortunately, finding your tank is not always simple, and many plumbers charge extra to discover them, which is especially true if your septic tank lid is hidden beneath the earth.

A soil probe is one of the most useful instruments for locating a septic tank.
Start at the point where your sewage line exits your home and work your way straight out, inserting your soil probe every two feet along the way.

Using this method, you may also locate the cover for your septic tank.
While we highly advise keeping your cover clean and exposed in the event that you require emergency septic service, we recognize that this is not always the case.

2. Use a Septic Tank Map

If you are a new homeowner who is trying to figure out where your septic tank is, a septic tank map should be included in your inspection documentation. You can use this information to assist you in pinpointing the exact position of your storage tank. If you don’t have access to this map, there are a few of additional strategies you might employ.

3. Start Ruling Areas Out

The location of a septic tank cannot be constructed in specific areas due to the risk of causing major damage to your property or tank, as specified by local rules. Your septic tank will not be affected by the following:

Immediately adjacent to your well
Beneath your home

Directly against your home
For example, underneath your driveway
Under trees

And other locations. Structures like a patio or deck are good examples of this.

4. Inspect Your Property

If you take a hard look around your land, there’s a high possibility you’ll be able to locate your septic tank without having to do any probing whatsoever. In many circumstances, a septic tank may be identified by a slight dip or slope on your land that cannot be explained by any other means. Due to the fact that the hole that your contractors excavated for your septic tank may not have been exactly the proper size, they proceeded to install the tank anyhow. This is a rather regular occurrence.

When there is a minor divot or depression, it indicates that the hole was too large and that your contractors simply did not fill the depression to level the hole.

The likelihood of your septic tank being discovered in a few specific locations is quite high. Because of code issues or just because it doesn’t make sense, it’s highly unlikely that your septic tank will be located near any of the following locations:

Your water well, if you have one (for a variety of reasons that are rather clear)
Any paved surfaces (it won’t be under a patio, sidewalk, or driveway unless they were added after the home was built and no one performed a proper inspection before it was built)

Any paved surfaces (it won’t be under a driveway, sidewalk, or patio unless they were added after the home was built and no one conducted a proper inspection before it was built)
Any paved surfaces (it won’t be under a patio, sidewalk, or driveway unless they were added after the home was built If there is any particular landscaping

5. Inspect Your Yard

Your water well, if you have one (for a variety of reasons that are quite self-explanatory); Any paved surfaces (it won’t be under a patio, sidewalk, or driveway unless they were added after the home was built and no one performed a proper inspection before it was built); any paved surfaces (it won’t be under a driveway unless it was added after the home was built and no one performed a proper inspection before it was built); any paved surfaces (it won’t be under a patio, sidewalk, or driveway unless they were added after the home was built and no one conducted Landscaping that is distinctive;

Your water well, if you have one (for a variety of rather apparent reasons)
Any paved surfaces (it won’t be under a patio, sidewalk, or driveway unless they were added after the home was built and no one performed a proper inspection before it was built)
Any paved surfaces (it won’t be under a driveway unless it was added after the home was built and no one conducted a proper inspection before it was built)

Any paved surfaces (it won’t be under a patio, sidewalk, or driveway unless they were added after the home was built and no one conducted Landscaping that is unique

The metal soil probe can let you find out for certain whether or not your septic tank is located in a certain area of your yard or not. As soon as your metal soil probe makes contact with the tank, you may use your shovel to dig out the grass surrounding it and discover the septic tank lid.

6. Follow Your Sewer Main/Sewer Pipes

Following your sewage lines is one of the most straightforward methods of locating your septic tank. These pipes have a diameter of roughly 4 inches and are commonly found in the basement or crawlspace of your house. They are not dangerous. Following the pipes from your house out into your yard, using your metal soil probe every 2 feet or so until you reach the tank, is a simple process once they are located. Aside from that, every drain in your home is connected to your sewage main, which in turn is connected to your septic tank.

The likelihood that one of your major sewer lines is located in your basement or crawlspace is high if you have exposed plumbing lines in your basement or crawlspace.

If the line is labeled, it is usually made of plastic or rubber.

7. Check Your Property Records

Lastly, if all else fails, a search of your property’s public records will almost certainly reveal the location of the tank you’re looking for. Your builders most likely secured a permit for your property because septic systems are required to be installed by law in every state. In order to do so, they had to develop a thorough plan that depicted your property as well as the exact location where they intended to construct the tank. This is done to ensure that the local health department is aware of the tank and is prepared to deal with any issues that may arise as a result of its presence.

If you look hard enough, you may be able to locate the original building records for your home without ever having to get in your car or visit your local records center. Some localities make these records public on the internet, whereas others do not.

What to Do Once You Find Your Septic Tank

Upon discovering the position of your septic tank, you should mark its location on a map of your property. Use something to indicate the location of your lid, such as an attractive garden item that can’t be changed, to help you locate it. A birdbath, a rock, or a potted plant are just a few of the possibilities. You are now ready to arrange your septic tank inspection and pumping service. Contact us now! If you have any more concerns regarding how to locate your septic tank, or if you want septic tank servicing, please contact The Plumbing Experts at (864) 210-3127 right now!

How Low Can You Go?

Upon discovering the position of your septic tank, you should mark the site on a map of your property. A ornamental garden element that can’t be readily relocated should also be used to designate the location of the lid when it’s closed. A birdbath, a rock, or a potted plant are just a few examples of what you might use. The time has come for you to arrange for a septic tank checkup and pumping service. Call The Plumbing Experts at (864) 210-3127 if you have any more concerns about how to locate your septic tank or if you want septic tank servicing right away.

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.

What you should expect when your septic tank needs pumping

The following are general recommendations: It is advised that you pump your septic tank every two to three years. The frequency with which you pump is determined by the volume of water you utilize. Generally speaking, the more individuals that use your septic system, the greater the increase in water flow. As a result, your septic tank will fill up more quickly, necessitating more regular pumping. It is likely that the septic tank will need to be pumped more frequently than every two to three years.

Choosing a certified pumper

We recommend that you identify your septic tank before contacting a pumping company. Here is a list of questions you should ask the pumper about their services that we recommend you ask:

What is the approximate cost of the pump-out
And Will additional gallons be charged if the septic tank has a capacity more than 1,000 gallons? Is it included in this price the expense of excavating to expose the septic tank lid(s)

If not, do you charge by the foot or by the meter? How much do you charge to dig you out if you don’t have one
Is there a charge for dumping costs included? Was it determined that this fee includes a visual check of the septic tank’s entrance and exit baffles? Do you charge an additional fee for cleaning the filter baffle? If a tank has not been properly maintained, is there an additional price for the additional water and time necessary to pump it out? (for example, pumped on a regular basis)
Please specify the distance and elevation to where the Pumper’s vehicle will be stationed if you have a long distance to pump or if you will be pumping up a steep hill (for example, in your driveway or in the yard). The Pumper will decide whether or not the vehicle is capable of providing this sort of service. Is pumping the pump tank a frequent component of your routine maintenance? What is the cost of providing this service? It is recommended that a pump tank be pumped in addition to the septic tank, cleaned with water, and then dried with a blow dryer. If the pump tank is extremely full, you may be subject to an additional price.

Locating the septic tank

Once you’ve decided on a Pumper, you’ll need to locate the septic tank on your property. Most Pumpers will charge you for the time it takes to locate the tank and open the septic tank lid (s). You can perform the necessary work to expose the septic tank lid(s) prior to the arrival of the Pumper. In order to make septic tank pumping and inspection trips easier and less time-consuming, the Ohio Department of Public Health advises that you install “risers.” With locking gas tight lids linked to both the tank and the riser and access raised to the surface, there is no digging required every time the septic tank needs to be pumped.

The majority of septic system pumpers will be able to do this service for you.
Both compartments must be examined and pumped in order to meet the requirements.
The location of your septic tank will be straightforward if you have an as-built (a map of your septic system) for your system.
The following talents will be required by you or your Pumper if an as-built is not available: investigation

Once you’ve decided on a Pumper, you’ll need to locate the septic tank on your property. You will be charged by the majority of Pumpers to locate your sewage tank and to open the septic tank lid (s). Preventing your septic tank lids from being exposed before the Pumper comes is something you can do on your own time. In order to make septic tank pumping and inspection trips easier and less time-consuming, the Ohio Department of Health advises that you install “risers.” In order to avoid digging every time the septic tank is pumped, a riser has locking gas tight lids linked to the tank and access provided to the surface. Pumping and inspections are less messy and disruptive in your yard as a result of this. Septic system Pumpers will be able to perform this service for the majority of their customers. The tank covers must be removed from both compartments if you have a 2-compartment tank (most residences constructed from 1975 to current have 2-compartment septic tanks). Inspecting and pumping both compartments is required by law. If the second compartment is not pumped, it will ultimately get clogged with sediments, causing issues in the system. The location of the septic tank will be straightforward if you have an as-built (a map of your septic system) for your system. Access your as-built drawing by searching for and downloading a copy. The following investigative abilities will be required if an as-built is not readily available:

Using an electronic detecting equipment may be essential if none of the above mentioned approaches prove successful. Some rental services contain a transmitter that may be flushed down the toilet and is detected by a receiving unit, which can be found in some rental services. In certain cases, drainfield location is the specialty of septic system contractors. See a list of septic system installers who are certified. As long as the tank is exposed, sketch a map depicting the location of the septic tank lid(s) in relation to the home and make a copy of the map for your records.

Pumping the septic tank

Before the Pumper begins the process of pumping out the tank, you may request that he measure the thickness of the scum and sludge layer layers on the inside of the tank. Using this method, you can determine the pace at which the particles collect in the tank, which will assist you in determining when it is necessary to have the septic tank pumped again. Pumping frequency will be in the range of 2 to 3 years for the vast majority of families. It doesn’t matter how often you pump your septic system; frequent inspections will provide you peace of mind that everything is in working order inside those tanks.

Concerning the inspection of your septic system. The septic tank Pumper should present you with a receipt that details the services that were done to your tank. This receipt should contain the following information:

The company’s name, address, and phone number
Pumper’s certification number
Number of gallons that were pumped in an approximate manner the number of compartments that have been pumped In good working order, the tank baffles In-tact condition of the septic tank
Provide specifics on any work performed on baffles or access lids. This information should be included on the pump receipt if the scum and sludge layers were measured. Any work done on the septic tank or pump tank should be documented. Any additional service work that is completed

Dig the Correct Cover

Organizational information such as name, location, and phone number A certified Pumper’s name and contact information The approximate amount of gallons that have been pumped out; Pumping capacity in compartments tank baffles are in good condition In the case of the septic tank, Include any modifications made to baffles or access doors. This information should be included on the pump receipt if the scum and sludge layers were measured. any repairs or upgrades to the septic tank or pumping system Service job performed in any other capacity.

Locate the 4′′ sewage pipe that runs from your toilet and shower to the exterior wall of your home. It should be visible. Most of the time, your tank is 8 to 15 feet from the place where the sewer pipe exits
Perhaps you have seen an area outdoors where snow melts each winter
Most of the time, this location is within the 8 to 15-foot range. This is an excellent place to begin. To identify the four corners of the tank, probe the ground with an abar and mark the locations. A septic tank measures roughly 8 feet long by 5 feet broad and is covered with three different types of coverings. Some tanks, on the other hand, are longer and made of plastic, making them more difficult to spot. Our company, Maine SepticPumping, requests that you find and excavate the center cover in order for us to thoroughly clean and remove any sediments from your tank. If you have a septic system that includes a pump, you should exercise caution. Unground electrical wire will be present, and it is possible that it could pose a hazard. You should also find and dig the cover for your pump chamber so that it can be pumped at the time of our service
If you are experiencing sluggish drains and the digging is relatively simple, you can try excavating all of the tank covers. All of the covers being removed would allow us to inspect your input region and eliminate any sediments that may be blocking the passage of the water. This also allows us to view your outlet baffle clearly, allowing us to ensure that it is secure. If you have any questions when trying to locate your tank, please contact our office. MaineSepticPumping can also assist you in locating and digging your cover.

Septic System Frequently Asked Questions

A septic system, sometimes known as a septic tank, is an underground system that processes the sewage that flows from your house before disposing of the treated, cleaner water. Septic systems are typically seen in residential areas. The treated water is subsequently re-introduced into the environment through filtration. This is critical because untreated sewage may harm nearby streams and water systems, as well as the soil around the perimeter of your septic system. Because your septic system is designed to cleanse and filter sewage, it is critical that it is in proper operating order.

What is a Drainfield?

The drainfield, also known as the leach field, is the area where the water from your septic system is sent after it has been cleansed and filtered. It is necessary to construct a drainfield in order to ensure that water is distributed uniformly back into the soil.

How do I find my septic system?

If you’re fortunate enough to have a contemporary septic system in your yard, it may be equipped with an access lid that is visible from the ground floor. If this is the situation at your residence, locating your septic system is as simple as taking a few steps into your backyard. It’s unfortunate that this isn’t true for older septic systems. It’s possible that you may locate an older system in your home by checking for greener, faster-growing grass or even an area with less growth than the rest of your yard if you live in an older home.

This will show you exactly where your septic system is located in your yard, if you have one.

You’ll need to look for the location where your septic system’s sanitary line exits your home and follow that line until you find your septic tank, which will take some time.

If you are unable to discover your septic system, your yard may need to be dug up by a septic system installation in order to locate your septic tank as a last option.

How long do septic systems last?

Septic systems are not designed to endure for a specific number of years, thus there is no defined time frame. In the event of adequate maintenance, you may expect your septic system to last several decades before it has to be replaced; but, if your system fails or deteriorates as a result of bad care, its lifespan will be drastically diminished. In order to obtain an accurate estimate of how much longer the life of your septic system may be extended, you must first have it checked thoroughly by an experienced septic system installation or repairer.

However, if you are confident that your tank is in good condition, the date of installation should provide you with an indication of how long it will endure.

What’s the advantage of installing a newer septic system rather than an older system?

Although it is not required to install a new system, there are advantages to having a modern septic tank rather than an older one. For starters, when you get a new septic tank, you can be confident that it will serve you for decades if it is properly maintained, and you will not have to worry about it being “too old.” Additionally, newer systems have been modified to reduce the likelihood of your system becoming clogged, and if something does go wrong with a new system or when it comes time to have your septic system pumped, a new system will likely be easier to locate because they are frequently constructed with ground-level lids.

New septic systems also provide a further treatment for your waste water, allowing it to be cleaner before it is released into the surrounding environment.

How much does a new septic system cost?

Installation of new septic systems may be a significant financial commitment, with costs typically reaching tens of thousands of dollars. Whenever you have to replace an outdated septic system, you should look into financing alternatives that will make it simpler for you to pay for a new septic system in the long run. Purchase further information from a septic system installation business on how to obtain septic systems at the most competitive prices while also taking advantage of low-interest financing options.

How big is my septic tank?

Septic tank capacity is determined by the amount of water consumed in your property as well as local codes and requirements. Check with your local health agency to find out how big your tank is before installing it.

Why should my septic system be pumped out?

Without regular pumping, the gases emitted by human waste accumulate in your septic system, increasing the risk of septic tank damage and the need for more frequent pumping. The regular pumping of your septic system will allow you to limit the rate at which your tank deteriorates and save money in the process. It’s crucial to remember, though, that degeneration is unavoidable in the long run. It is only via regular maintenance, such as pumping your tank, that your septic system will survive longer.

Does my tank need to be dug up to know if it needs to be pumped?

Risers are commonly found in newer septic systems, which allow you to access your tank from the ground level through a lid. It is straightforward for any septic system professional to determine whether or not your yard has risers placed, and whether or not it is necessary to pump it. If, on the other hand, your tank cannot be accessible from the ground level, it will need to be dug up in order to determine whether it has to be drained.

Instead of inspecting your septic system to see whether it needs to be pumped on a regular basis, set a timetable for having your system pumped every 2-3 years.

Why should I have risers and lids installed on my septic system?

Riser systems, which allow you to reach your tank from the ground level through a lid, are common in newer septic systems. It is straightforward for any septic system professional to determine whether or not your yard has risers placed, and whether or not it is necessary to pump your system. When a tank cannot be accessible from the ground level, it will need to be dug up in order to determine if it requires pumping or not. In order to avoid the hassle of inspecting your septic system to see whether it need pumping, set up a timetable that has your system pumped every 2-3 years.

How often should my septic system be pumped out?

A typical septic system contains a 1,500-gallon tank, which needs to be pumped around every 2-3 years for a household of four, according to industry standards. If you have less than four people living in your house, you will most likely be able to pump your septic system every five years rather than every three. You should speak with your local health agency to determine the exact size of your tank, and you should consult a septic system business to determine how frequently your tank should be pumped based on the size of your family and the size of your septic tank.

Do I need to have the septic tank pumped if I’m selling my house?

Consult with your local health department to learn about the restrictions that apply to your region of residence. Generally speaking, as long as your septic system has been pumped on a regular basis by a licensed septic system company and recently enough for the new homeowners to be able to live there for a year or two without having to pump the septic system, you should not be required to have it pumped again in the near future.

How do I find someone to pump my septic system?

It is important to be aware that not all septic system businesses are licensed and that not all firms properly dispose of or recycle the waste they pump from your septic system when you are looking for one to pump it. Finding a firm that complies with EPA standards should be your first concern, and then you should look at price, how pricing is split down, and which company is delivering the most honest, economical, and dependable service should be your next consideration. Investigate business evaluations, and when you select a septic system provider to pump your septic tank, be certain that they do the work properly, leaving enough water and waste to keep the sewage decomposing while leaving no visible trace more than a few inches of waste behind.

How much does it cost to have my septic system pumped?

It is recommended that you call many pumpers before making a selection, and that you ask as many questions as possible to ensure that you are receiving the best service for your money. Pumping may cost upwards of $200, so it is always wise to shop around before making a decision.

You should not consider it a waste of money to have your septic system pumped when the time comes. By correctly maintaining your septic system, you may avoid spending tens of thousands of dollars to replace your septic system long before it should have been replaced in the first place.

What happens if I don’t have my septic system pumped?

The sediments will pile up in your septic tank if you don’t pump it out regularly, ultimately overflowing into the drain field and clogging the drain field. Backups can occur, causing damage to your property and even necessitating the replacement of your drain field, which can be a very expensive error.

I just had my septic system pumped. Why is it full already?

Septic systems are designed to refill rapidly since the purpose of pumping is not to remove water but rather to remove non-biodegradable waste, and the water itself is not the aim of pumping. Once your septic system has been pumped and you begin to use the water in your house, your tank will quickly refill in order to maintain good operation of the system. If the water level rises to a point where it is above the outlet line, contact your septic system service provider for assistance immediately.

What do you look for when inspecting my septic system?

When we do an inspection, we make certain that your septic system is in good operating condition and that it satisfies the standards for receiving a Certificate of Compliance. If you’re planning to sell your home, you should have your septic system checked out by a professional who is certified by the Minnesota Pollution Control Agency. This will allow you to sell your home faster and for more money, if you can prove that your system has been checked out by an accredited professional. The level of liquid in your septic tank will be checked, and we’ll make sure there is no surface-level discharge.

The drains in my home aren’t draining as quickly as they normally do. Does this have to do with my septic system?

Drains that are clogged and that empty slowly are not necessarily a big source of concern. Before presuming that there is an issue with your septic system, check sure that there isn’t anything obstructing your drain first. In the case of one plumbing fixture in your house that is draining slowly, it is likely due to clogging; however, if all of the drains in your home are slow or leave waste backed up, it is probable that your septic system requires inspection and may even require pumping.

What happens when my septic system fails?

Symptoms of a failing septic system may include minor issues such as drain breaks or pipes that have been stopped, which can be caused by tree roots intersecting with the system. Septic system failure, on the other hand, might indicate that your septic tank has degraded to the point that it cannot be repaired and must be replaced. A blocked drainfield will hopefully not become your problem because it is the most expensive component of your system to replace; nevertheless, if it does, you must act quickly to make the necessary repairs or else your waste will continue to back up, perhaps causing damage to your property.

A blocked drainfield is likely the reason of your sluggish draining pipes, damp yard above your tank or drainfield, sewage stench coming from your yard, or tainted well water. You’ll need to replace the drainfield as soon as possible to avoid further pollution of drinking water sources.

How do I prevent my septic system from failing? How can I properly maintain my septic system?

Your septic system should degrade at a normal rate over the course of several decades if you maintain it on a regular basis. Maintenance normally consists of getting your septic system pumped on a regular basis and making certain that you do not flush or wash anything down the drain that might block your septic system.

What shouldn’t I flush down the toilet?

As a general rule, only human waste and toilet paper should be flushed. There are several reasons why flushing medicine down the toilet is not a good idea. First, medication might kill some of the bacteria in your septic tank, which is necessary to break down solid waste. Second, drugs can pollute adjacent well water. In addition, you should avoid flushing feminine hygiene items, paper towels, tissues, hair, cat litter (even if it is flushable), diapers, wipes, condoms, cigarettes, and anything else that seems to be inorganic and shouldn’t be flushed down the toilet.

What shouldn’t I pour down the drain?

Grease from the kitchen, motor oil, anti-freeze, gasoline, paint, and food should not be flushed down the toilet or drain. You should avoid flushing anything down your drain other than soap and water, and you should especially avoid flushing any form of chemical down your drain that should not be recycled back into the environment, such as fertilizer.

Is using a garbage disposal bad for my septic system?

Using a trash disposal will result in the requirement to pump your septic system more frequently than you would otherwise need to do if you avoided flushing food particles down your drains. Too much food collection in your tank might cause your drainfield to clog since the microorganisms in your tank are not capable to digesting it. When using a trash disposal, check with your septic system company to find out how frequently the disposal should be serviced.

Should I add bacteria to my septic system?

Aside from being completely useless, introducing bacteria to your septic tank is also highly discouraged. The bacteria produced by human waste is sufficient to break down the solid sewage in your tank without the need of bacteria supplements or other methods. If, on the other hand, multiple members of your home are using pharmaceuticals, they will enter your septic system through human waste and kill some of the beneficial bacteria in your tank, causing it to malfunction. Please contact the firm who installed your septic system to see whether or not you should be worried about the amount of bacteria-killing compounds entering the system.

There’s a strong sewer odor outside of my house. Could this be my septic tank?

Strong sewage stench coming from your yard might be coming from your septic system, but it could also be coming from someplace else completely. Identifying the source of the smell is important. Check for propane or gas leaks in your home before concluding that your septic system is at fault; however, if your gas or propane lines are not leaking, determine how long it has been since you had your tank pumped, and whether there is any sewage waste in your yard or other signs of septic system failure before making your final decision.

Can my septic system contaminate nearby water?

It is possible for your septic system to pollute surrounding water sources if it is not properly managed or fails completely.

In the event that you suspect that your septic system is failing, make sure that it is routinely pumped and inspected by an expert.

My gutters’ downspouts drain into my yard above my septic system. Is this a bad thing?

The drainage of your gutters into your yard above your septic system, and particularly into your drainfield, can be hazardous to your septic system. All water should be diverted away from your septic system in order to minimize flooding and damage to your septic system’s tank or drain field.
