How Big Are Holes In Septic Tank? (Solution)

Slope of the watertight pipe should be a minimum of 1/4-inch per foot toward the field to prevent clogging. Holes in the perforated pipe should be 1/2- to 3/4-inch in diameter.

  • Soil Perc Test Hole Depth: A typical soil perc test hole like the one shown at the top of this page or pit is dug at least 4 1/2 ft. deep and usually five feet (5′) deep. On occasions a 6′ hole is used if the approving health or building department septic inspector or engineer so requires.

Do septic tanks have holes?

The septic tank acts like a settling pond. Holes in the drain septic field pipe allow effluent to seep into surrounding gravel. Gravel around pipes allows water to flow into soil and oxygen to reach bacteria. 8.

How deep is the hole for a septic tank?

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.

What are the sizes of septic tanks?

Standard tank sizes are typically 1,000, 1,250 and 1,500 gallons, and these suit most homes. Typically, the minimum tank liquid capacity of a one- to three-bedroom home is 1,000 gallons.

What are the signs that your septic tank is full?

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

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

How far down is a septic tank lid?

Often, septic tank lids are at ground level. In most cases, they have buried anywhere from four inches to four feet underground.

What size are concrete septic tanks?

What sizes do concrete septic tanks come in? Standard tank sizes are 1000 gallon, 1250 gallon, and 1500 gallons nationwide.

How big is a septic tank lid?

Locate The Lid Most septic tanks are rectangular and measure about 5 feet by 8 feet. Probe around the tank to locate its edges and mark the perimeter of the rectangle. A septic tank installed before 1975 will have a single 24-inch concrete lid in the center of the rectangle.

How big is a leach field?

The leach field is a series of trenches that may be up to 100-feet long and 1 foot to 3 feet in width, separated by six feet or more, depending on local requirements, and sometimes constructed leaving space between the original lines to install replacement leach lines when needed.

Does every house have a septic tank?

A septic tank is a crucial part of a home’s septic system. In the U.S., about 20% of homes use a septic system to manage their wastewater. Septic systems are most commonly found in the Eastern U.S., with homes in rural areas of New England being the most likely to have a septic system present.

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.

Can a septic tank be too big?

A septic tank that is too big will not run well without the proper volume of wastewater running through it. If your septic tank is too big for your house, there wouldn’t be sufficient collected liquid required to produce the bacteria, which helps break down the solid waste in the septic tank.

Do septic tanks come in different sizes?

The correct size of the septic tank depends mostly on the square footage of the house and the number of people living there. Most residential septic tanks range in size from 750 gallons to 1,250 gallons. An average 3-bedroom home, less than 2500 square feet will probably require a 1000 gallon tank.

Drainfield Size & Design

  • The percolation rate of a soil is an essential soil feature that measures how long it takes water to descend one inch in a saturated hole drilled in the ground.
  • The percolation rate, which is an essential soil feature, estimates how long it takes water to sink one inch in a saturated hole drilled in the ground.
  • If it takes less than 5 minutes for water to drop 1 inch in a saturated hole, the effluent will move too quickly for it to be properly treated, as is the case in sandy soil. If it takes more than 60 minutes for the water to drop one inch, the effluent will not be able to move as quickly as it should, and effluent may rise to the top of the water table. This is something that can happen in clay soil.

Drainfield Size

  • For example, if it takes less than 5 minutes for water to drop 1 inch in a saturated hole, the effluent will flow too quickly for it to be adequately treated, as is the case with sandy soil. If it takes more than 60 minutes for the water to drop one inch, the effluent will not be able to travel as quickly as it should, and effluent may rise to the top of the water column. If you have clay soil, this is something that can happen.

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:

  1. 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

Author:Phil HWhat you are describing is a very crude cesspool. At one time, it was common to have a brick or block lined hole for private sewage disposal. They have largely been eliminated because of the potential to contaminate ground water. You should contact the local health department and building department and see if this is a viable option for new construction. There may even be epa regulations that prohibit installing a new cesspool.

How To Deal With An Abandoned Septic Tank System – B&B Pumping – Top Rated Septic Cleaning Services

Septic systems are one of two contemporary options for properly disposing of human waste (the other being connected to your city’s sewage system), and they are becoming increasingly popular. That this is crucial cannot be overstated since human waste, when it contaminates our water supply, can create deadly infections that can lead to death, as was commonly the case hundreds of years ago before the development of modern sewage systems. Septic Pumping Services by B B Pumping Cleaning your home or business septic system in the Fort Worth region is the focus of Aerobic Cleaning’s services.

Septic systems, on the other hand, can be abandoned from time to time, whether by previous homeowners, present homeowners, or those who have been foreclosed upon.

In this blog post, we’ll go over some of the procedures that must be followed when dealing with a septic system that has been abandoned. Contact us immediately if you live in or around the greater Dallas/Fort Worth region!

HOW ARE ABANDONED SEPTIC SYSTEMS DANGEROUS TO HUMANS?

  • Sinkholes. Septic systems are built beneath the ground surface. When these systems are abandoned with human waste and water sitting in them, the water and waste have the potential to disintegrate the underlying rock and erode the surrounding landscape. When enough of this rock has dissolved, a hole of sorts is left in the ground, and the soil above it is no longer able to sustain itself. When the earth finally collapses, it is generally as a result of an external force acting on it, such as when you walk across it. Diseases that are extremely dangerous. It is possible for people to get infections when human waste comes into contact with our drinking water supply. Diseases such as tetanus, hepatitis A, leptospirosis, cholera, dysentery, and gastrointestinal sickness have been linked to this situation. Gases that are toxic. Gases such as methane and hydrogen sulfide can accumulate in abandoned septic tank systems, posing a risk of explosion or illness to anyone exposed. This is related to the decomposition of human feces, which occurs when it is left in one location exposed to the elements.

Cesspools, which were little more than a large pit under your yard where human waste was flushed, were commonly used in homes built before city sewer systems became the standard (mostly before the 1970s). When the city sewage system was eventually able to provide service to these properties, many of the cesspools and old septic tanks were simply abandoned and neglected, with little effort made to ensure that they were properly turned off. The owner of BB Pumping in Fort Worth points out that local laws have been put in place to ensure that your septic system has been properly abandoned before connecting to the municipal sewage system.

SIGNS OF AN OLD ABANDONED LEAKING SEPTIC TANK SYSTEM

  • If you have an excessive amount of weed growth on your lawn, or if you have a pond on your property, you may see a lot of algae development
  • The same part of your grass never appears to be able to dry up fully, and it is always damp
  • A specific region of your yard has an awful odor, similar to that of human feces. When compared to the rest of your lawn, a portion of your lawn appears to be unstable and may be sinking in
  • However, this is not the case. You can see the pipes that are part of the dispersion system. Surface erosion, for example, might cause them to be pushed up from the ground by water or other factors.

HOW TO PROPERLY ABANDON A SEPTIC TANK SYSTEM

  1. Make use of the services of specialists. Most likely, you’ll be required to demonstrate that your septic tank system has been abandoned in accordance with the city’s regulations, which a professional septic tank system firm, such as BB Pumping in Fort Worth, can attest to in this scenario. The majority of people just lack the necessary information to properly decommission a septic tank system. Apart from that, it is filthy, difficult work that is best left to professionals who are qualified to perform it quickly and effectively rather than you spending hours and hours attempting to do it yourself. The septic tank must be entirely emptied and properly disposed of. We utilize a powerful vacuum to pull the muck out of the tank and into our trucks, where it can then be hauled to the appropriate location for proper disposal
  2. When we empty a septic tank, we use a high-powered vacuum to pull the muck out of the tank and into a storage tank on our trucks, where it can then be hauled to the proper location for proper disposal
  3. Remove the tank from the vehicle. In some cases, the procedure may alter depending on the local codes. For those who want to have their septic tank removed, there are various possibilities. One option is to remove the entire tank and dispose of it in a landfill, which seems likely. You may totally crush the tank and backfill it, making sure that the tank has a hole in it for adequate drainage of rainfall in the process. Another option is to fill the tank with a substance such as concrete or another granular material and then cover it with another material (making sure that is a drainage hole as well). In this case, it’s critical to recall that there is no chance that the tank may collapse in the future
  4. Determine whether or not the dispersion system needs to come out of service. A dispersion system, which drains the treated material onto what is usually known as a leach field, where the material is cleaned through the soil process, is typically installed after the human waste has been treated in the septic tank. These pipes may need to be removed in certain cases, but they may also be able to be kept underground in others. It is necessary to take additional measures since human excrement has come into touch with the soil in this location
  5. Otherwise, the pipes will have to be removed. Dispose of any electrical components or gadgets in the proper manner. Modern septic tank systems might have electronics installed that monitor your septic tank system, but previous systems may have employed mercury floats that must be properly disposed of before backfilling the tank with water. All wires should be disconnected, and the conduit should be sealed with a cover. Mercury is considered to be a hazardous substance, which is another another reason why you should entrust your septic system abandonment to the pros at BB Pumping in Fort Worth to handle it for you. Fill in the gaps. This frequently necessitates the hauling in of more earth, especially if the septic tank is removed in its entirety. For the purpose of ensuring the general public’s safety, this is the most critical component.

HOW BB PUMPING IN FORT WORTH CAN HELP

Engage the services of a qualified expert. As a result, a professional septic tank system firm, such as BB Pumping in Fort Worth, will likely be required to attest to the fact that your septic tank system has been abandoned according to local regulations. Septic tank systems are commonly abandoned simply because most individuals do not have the necessary understanding. Apart from that, it is filthy, difficult work that is best left to professionals who are qualified to perform it quickly and efficiently rather than you spending hours and hours attempting to do it yourself.

We utilize a powerful vacuum to pull the muck out of the tank and into our trucks, where it can then be hauled to the appropriate location for proper disposal; when we empty a septic tank, we use a high-powered vacuum to pull the muck out of the tank and into a storage tank on our trucks, where it can then be hauled to the appropriate location for proper disposal.

  • This approach may change depending on the laws in your area.
  • For starters, it is possible to remove the tank in its entirety and have it dumped elsewhere, perhaps in the landfill.
  • Alternatively, you may fill the tank with a filler material such as concrete or another granular material and then cover it with a lid (making sure that is a drainage hole as well).
  • A dispersion system, which drains the treated material into what is usually known as a leach field, where the material is further cleaned through the soil process, is typically installed after the human waste has been treated in the septic tank.
  • Due to the fact that human excrement has come into touch with the soil in this location, particular care must be taken when the pipes are taken out.
  • Modern septic tank systems might have electronics installed that monitor your septic tank system, but previous systems may have employed mercury floats that must be properly disposed of before backfilling the tank with waste.
  • Aside from the fact that mercury is considered a dangerous substance, there is another reason why you should delegate your septic system abandonment to the pros at BB Pumping in Fort Worth.

In many cases, especially if the septic tank is removed in its entirety, more soil must be carried in. For the purpose of ensuring the public’s safety, this is the most critical component.

Standard Septic Systems

When it comes to treating residential wastewater, a regular wastewater system combined with a soil absorption system is the most cost-effective technique currently available. However, in order for it to function correctly, you must select the appropriate septic system for your home size and soil type, and you must keep it in good working order on a regular basis.

What size septic tank do I need?

Septic tank size requirements are determined by the number of bedrooms in a house, the number of people who live there, the square footage of a house, and whether or not water-saving gadgets are installed. If you want to obtain a general sense of what size septic tank your home requires, look at the table below.

Bedrooms Home Square Footage Tank Capacity
1 or 2 Less than 1,500 750
3 Less than 2,500 1,000
4 Less than 3,500 1,250
5 Less than 4,500 1,250
6 Less than 5,500 1,315

How often should my tank be pumped?

A regular pumping of the tank is required to maintain your system operating properly and treating sewage efficiently. Sludge collects at the bottom of the septic tank as a result of the usage of the septic system. Because of the rise in sludge level, wastewater spends less time in the tank and solids have a greater chance of escaping into the absorption region. If sludge collects for an excessive amount of time, there is no settling and the sewage is directed directly to the soil absorption region, with no treatment.

  • You can find out how often you should get your tank pumped by looking at the table below.
  • If you fail to maintain the tank for an extended period of time, you may be forced to replace the soil absorption field.
  • Solids can enter the field if the tank is not pumped on a regular basis.
  • Wet soils that have been saturated by rains are incapable of receiving wastewater.

Other maintenance

Another maintenance activity that must be completed on a regular basis to protect the system from backing up is to clean the effluent filter, which is located in the tank’s outflow tee and is responsible for additional wastewater filtration. This filter eliminates extra particulates from the wastewater and prevents them from being clogged in the absorption field, which would cause the absorption field to fail prematurely. You may clean the filter yourself by spraying it with a hose, or you can have your maintenance provider clean the filter for you if necessary.

Two critical components

A septic tank and a soil absorption system are the two primary components of a standard treatment system.

Tank

The septic tank is an enclosed, waterproof container that collects and treats wastewater, separating the particles from the liquid. It is used for primary treatment of wastewater. It works by retaining wastewater in the tank and letting the heavier particles (such as oil and greases) to settle to the bottom of the tank while the floatable solids (such as water and sewage) rise to the surface. The tank should be able to store the wastewater for at least 24 hours in order to provide time for the sediments to settle.

Up to 50% of the particles stored in the tank decompose, with the remainder accumulating as sludge at the tank bottom, which must be cleaned on a regular basis by pumping the tank out.

Drainfield

Ultimately, the soil absorption field is responsible for the final treatment and distribution of wastewater. Traditional systems consist of perforated pipes surrounded by media such as gravel and chipped tires, which are then coated with geo-textile fabric and loamy soil to create a permeable barrier. This method depends mainly on the soil to treat wastewater, where microorganisms assist in the removal of organic debris, sediments, and nutrients that have been left in the water after it has been treated.

As the water moves through the soil, the mat slows its passage and helps to prevent the soil below the mat from being saturated.

The grass that grows on top of the soil absorption system takes use of the nutrients and water to flourish as well.

Septic tank types

The ultimate treatment and distribution of wastewater are handled by the soil absorption field. Traditional systems consist of perforated pipes surrounded by media such as gravel and chipped tires, which are then coated with geo-textile fabric and loamy soil to provide a barrier from the elements. This method depends significantly on the soil to treat wastewater, where microorganisms assist in the removal of organic debris, sediments, and nutrients that have been left in the water after the water has been treated.

As the water moves through the soil, the mat slows its passage and helps to protect the area beneath the mat from being saturated.

The grass that grows on top of the soil absorption system takes use of the nutrients and water to thrive as well.

  • Concrete septic tanks are the most popular type of septic tank. Fiberglass tanks – Because they are lightweight and portable, they are frequently used in remote or difficult-to-reach sites. Lightweight polyethylene/plastic tanks, similar to fiberglass tanks, may be transported to “difficult-to-reach” sites since they are one-piece constructions.

It is necessary for all tanks to be waterproof in order to prevent water from entering as well as exiting the system.

Factors in septic maintenance

A critical consideration in the construction of a septic tank is the link between the amount of surface area it has, the amount of sewage it can hold, the amount of wastewater that is discharged, and the rate at which it escapes. All of these factors influence the effectiveness of the tank as well as the quantity of sludge it retains. The bigger the liquid surface area of the tank, the greater the amount of sewage it can hold. As more particles accumulate in the tank, the water level in the tank grows shallower, necessitating a slower discharge rate in order to give the sludge and scum more time to separate from one another.

An aperture must be utilized on the tank lid if it is more than 12 inches below the soil surface, and a riser must be used on the openings in order to bring the lid to within 6 inches of the soil surface.

It is quite simple to do maintenance on the tank thanks to these risers.

Soil types

There are three types of soil textures: sand, silt, and clay, and each has an impact on how quickly wastewater filters into the soil (a property known as hydraulic conductivity) and how large an absorption field is required. Sand transports water more quickly than silt, which transfers water more quickly than clay. According to Texas laws, these three soil textures are subdivided into five soil kinds (Ia, Ib, II, III, IV). Sandy soils are classified as soil type I, whereas clay soils are classified as soil type IV.

  • The Hydraulic Loading, which is the quantity of effluent applied per square foot of trench surface, is also significant in the design.
  • For this reason, only nonstandard drain fields are suitable for use in clay soils due to the poor conductivity of clay soils.

Understand that a septic system is a cafeteria for bacteria

Bacteria are responsible for the proper operation of a septic system. They decompose garbage, resulting in water that is clean enough to safely trickle down into the earth’s surface. The entire system is set up to keep bacteria healthy and busy at all times. Some of them reside in the tank, but the majority of them are found in the drain field. 1. The septic tank is the final destination for all waste. 2. The majority of the tank is filled with watery waste, referred to as “effluent.” Anaerobic bacteria begin to break down the organic matter in the effluent as soon as it enters the system.

  1. A layer of sludge settles to the bottom of the container.
  2. 4.
  3. Scum is mostly constituted of fats, greases, and oils, among other substances.
  4. Grease and oils float to the surface of the water.
  5. (5) A filter stops the majority of particles from reaching the exit pipe.
  6. The effluent is discharged into the drain field.
  7. Effluent is allowed to leak into the surrounding gravel because of holes in the drain septic field pipe.

When gravel is used to surround pipes, water can run into the soil and oxygen can reach germs. The garbage is completely decomposed by aerobic bacteria found in gravel and dirt. 9. Potable water seeps into the groundwater and aquifer system from the surface.

Septic Tank Clean Out: Don’t abuse the system

In order for a septic system to function properly, bacteria must be in the system. These organisms decompose garbage, resulting in water that is safe to pass through and percolate into the ground. The entire system is set up to keep bacteria healthy and busy at all time. Several species inhabit the tank, but the majority perform their functions on the drainage field. 1. The septic tank is the final destination for all waste. 2. 2. A large portion of the tank is filled with watery waste, referred to as “effluent.” Anaerobic bacteria begin to break down the organic matter in the effluent as soon as it enters the water system.

  1. A layer of sludge accumulates at the bottom of the container.
  2. Sludge is a mixture of inorganic particles and byproducts of bacterial decomposition that may be found in wastewater.
  3. A layer of scum rises to the surface of the water.
  4. Oil, fats, and grease are the primary components of scum.
  5. Grease and oils float to the surface of the water and accumulate on the surface.
  6. Five, a filter is used to keep most solids out of the exit pipe.
  7. In addition to providing a huge space for bacteria to flourish, the drain septic field also allows treated water to seep into the earth.
  8. It is possible for water to get into the soil and for oxygen to reach bacteria because of the gravel around the pipes.
  9. Aerobic microorganisms in the gravel and soil completely decompose the waste material.
  • Drains are used to dispose of waste that decomposes slowly (or not at all). Cigarette butts, diapers, and coffee grounds are all known to cause issues. Garbage disposers, if utilized excessively, can introduce an excessive amount of solid waste into the system. Lint from synthetic fibers is emitted from washing machine lint traps. This substance is not degraded by bacteria in the tank and drain septic field. Bacteria are killed by chemicals found in the home, such as disinfecting cleansers and antibacterial soaps. The majority of systems are capable of withstanding limited usage of these goods, but the less you use them, the better. When a large amount of wastewater is produced in a short period of time, the tank is flushed away too quickly. When there is too much sludge, bacteria’s capacity to break down waste is reduced. Sludge can also overflow into the drain field if there is too much of it. Sludge or scum obstructs the flow of water via a pipe. It is possible for tree and shrub roots to obstruct and cause harm to a drain field. Compacted soil and gravel prevent wastewater from seeping into the ground and deprive germs of oxygen. Most of the time, this is caused by vehicles driving or parking on the drain field.

Get your tank pumped…

Your tank must be emptied on a regular basis by a professional. Pumping eliminates the accumulation of sludge and scum that has accumulated in the tank, which has caused the bacterial action to be slowed. If you have a large tank, it may be necessary to pump it once a year; but, depending on the size of your tank and the quantity of waste you send through the system, you may go two or three years between pumpings. Inquire with your inspector about an approximate guideline for how frequently your tank should be pumped.

…but don’t hire a pumper until you need it

Inspections and pumping should be performed on a regular basis. However, if you’re not afraid of getting your hands dirty, you may verify the sludge level yourself with a gadget known as The Sludge Judge. It ranges in price from $100 to $125 and is commonly accessible on the internet. Once you’ve verified that your tank is one-third full with sludge, you should contact a professional to come out and pump it out completely.

Install an effluent filter in your septic system

Garbage from your home accumulates into three distinct strata. The septic filter is responsible for preventing blockage of the drain field pipes.

Septic tank filter close-up

The septic tank filter is responsible for capturing suspended particles that may otherwise block the drain field pipes. Obtain an effluent filter for your tank from your contractor and place it on the outflow pipe of your tank.

(It will most likely cost between $50 and $100, plus labor.) This device, which helps to prevent sediments from entering the drain field, will need to be cleaned out on a regular basis by a contractor to maintain its effectiveness.

Solution for a clogged septic system

The septic tank filter is responsible for capturing suspended particles that may otherwise block the drainage field pipes. Inquire with your contractor about installing an effluent filter on the outflow line from your storage tank. In addition to labor, it will likely cost $50 to $100. In order to prevent sediments from entering the drain field, this device must be cleaned out by a contractor on an as-needed basis.

Get an inspection

Following a comprehensive first check performed by an expert, regular inspections will cost less than $100 each inspection for the next year. Your professional will be able to inform you how often you should get your system inspected as well as how a septic tank functions. As straightforward as a septic system appears, determining its overall condition necessitates the services of a professional. There are a plethora of contractors who would gladly pump the sludge out of your tank, but many, in my experience, are unable to explain how a septic system works or how it should be maintained.

A certification scheme for septic contractors has been established in certain states; check with your state’s Secretary of State’s office to see whether yours is one of them.

Also, a qualified inspector will be able to tell you whether or not your tank is large enough to accommodate your household’s needs, as well as the maximum amount of water that can be passed through it in a single day.

As you learn more about how a septic tank works, your professional should be able to tell you whether or not your system will benefit from this treatment.

Alternatives to a new drain field

If an examination or a sewage backup indicate that your drain field is in need of replacement, the only option is to replace it completely. As a result, it’s important to talk with a contractor about other possibilities before proceeding with the project.

  • Pipes should be cleaned. A rotating pressure washer, used by a contractor, may be used to clean out the drain septic field pipes. The cost of “jetting” the pipes is generally around $200. Chemicals should be used to clean the system. A commercial solution (not a home-made one) that enhances the quantity of oxygen in the drain field should be discussed with your contractor before installing your new system. Septic-Scrub is a product that I suggest. A normal treatment will cost between $500 and $1,000. Make the soil more pliable. The practice of “terra-lifting,” which involves pumping high-pressure air into several spots surrounding the drain field, is authorized in some regions. Some contractors use it to shatter compacted dirt around the pipes. Depending on the circumstances, this might cost less than $1,000 or as much as $4,000 or more.

Protect your drain septic field from lint

When this device is in place, it inhibits lint from entering the system, especially synthetic fibers that bacteria are unable to digest. One of these filters, which I’ve designed and termed theSeptic Protector, was invented by me. An additional filter is included in the price of around $150 plus delivery. Learn more about how to filter out laundry lint in this article.

Don’t overload the septic system

This device prevents lint from entering the system, particularly synthetic fibers, which bacteria are unable to digest and hence cause infection.

Septic Protector is the name I gave to one of these filters that I designed myself. An additional filter is included in the price of roughly $150 plus delivery. See this article for further information on how to filter out lint from your clothes.

Meet the Expert

Septic systems, according to Jim vonMeier, are the solution to America’s water deficit because they supply cleaned water to depleted aquifers, according to vonMeier. He travels the country lobbying for septic systems, giving lectures, and giving testimony. For septic system inquiries, as well as information on the operation of the septic tank, contact him by email.

How to Find the Lid on a Septic System

All septic tanks eventually fill with sediments and must be pumped out on a regular basis in order to remain in excellent functioning order. If the tank’s lid is not on a riser at ground level and you are not the home’s original owner, you may be unable to determine where the lid is located. A typical septic tank is 4 inches to 4 feet underground, with all of its components, including the cover, buried between 4 inches and 4 feet underneath. This is true regardless of whether the septic tank is equipped with special risers that keep the lid flush with the surface of the ground.

Consult A Map

First, choose with the most straightforward choice. The installation of septic tanks at all locations is recorded in most counties’ permission records, which are kept on file for future reference. Typically, this will include a schematic indicating the placement of the tank on the land, as well as certain dimensions that will allow you to measure to the precise site of the tank. If your tank was placed before your county made it a requirement to record the location of such tanks, you may find yourself with nothing to show for your efforts.

Search For A Sign

Septic tanks are placed in such a way that they are as unnoticeable as possible on the land. After the grass has grown back after installation and some time has passed, it is possible that just a few visual indications will remain. Pay particular attention to the contours of your yard for any inexplicable high or low points that might suggest the presence of an underground storage tank.

Follow The Pipe

Installation of the septic tank takes place along the sewage line that runs from the house into the front yard. Locate the 4-inch sewage pipe at the point where it exits the home in the basement or crawl space, if it is there. Locate the same spot outside and make a note of it. Insert a thin metal probe into the earth, identify the 4-inch sewage line, and follow it across the yard, probing every 2 feet, until you reach the end of the property. Septic tanks are required to be at least 5 feet apart from the home in all states except Alaska.

Whenever the probe makes contact with flat concrete, fiberglass, or polyethylene it indicates that the tank has been located.

Locate The Lid

The majority of septic tanks are rectangular in shape and measure around 5 feet by 8 feet. Investigate the tank’s circumference to determine its boundaries and outline the rectangle’s boundary using a pencil. A septic tank that was built before 1975 will have a single concrete lid that is 24 inches in diameter in the center of the rectangle. If the tank was built after 1975, it will have two covers made of fiberglass or polyethylene, centered at the ends of the rectangle and centered at the ends of the rectangle.

It should be possible to uncover the lid or lids by digging with a spade in specific spots, depending on when year the tank was constructed.

Call A Professional

Opening a septic tank is a job best left to the pros once the lid has been discovered. Concrete septic tank lids are extremely heavy, and many require the use of lifting tools to remove them completely. An open tank has the potential to release toxic gases. Anyone going around on the property who comes into contact with an exposed septic tank might be in risk. Because of the noxious vapors present in an open tank, falling into one can be lethal.

Mark The Spot

Make a note on the ground near where the tank was pumped by a professional and the lid was buried to serve as a reference in the future. In order to keep track of where you are, you should choose a hefty circular patio tile that is embedded in the ground. Additionally, draw your own map of the area and store it with your other important papers.

Common Septic Tank Facts

Septic systems are a low-cost and frequently successful alternative to conventional sewer systems. Concrete tanks have been the most frequent since the 1940s, with 3 – 500lids for a 1000 gallon tank and 4 – 500lids for a 1500 gallon tank being the most typical. Tanks began to be equipped with 16″ square concrete plugs with a lifting bail in the late 1990s, allowing for easier access to both sides of the tank. Many tanks today are made of fiberglass or plastic. Over time, the concrete might degrade, and the lids may develop cracks or possibly shatter completely due to the pressure.

Even broken lids should be replaced for the sake of the public’s safety.

They get access to your septic tank by removing green covers that are 20 inches in diameter.

This is done in order to prevent anyone, especially children, from removing a lid and falling into the container.

A typical water level for a tank should be 6″ below the top of the tank, and the tank should be kept completely filled at all times.

The level of the water is often a good sign of potential problems.

Additionally, it might suggest a clogged intake line, which could be caused by roots, a damaged pipe, or a loose joint.

If there has been a lot of rain, the earth may get saturated, making it impossible for any additional water to seep through the soil to the surface.

If your tank has allowed particles to enter the field lines, this might cause the openings in the corrugated pipe to get clogged, preventing water from percolating through the soil as effectively as it should be.

An output filter may be placed to prevent particulates from entering the field lines, but it would need to be cleaned on an annual basis to ensure that this does not happen. Nonetheless, it is far less expensive than rebuilding field lines.
