What Happens To Septic Tank Sludge? (Solution)

Bacteria that lives in the tank helps to break down the sludge, turning it into a liquid. Near the top of the septic tank is a pipe that leads to a part of the yard called the drain field. When the waste water in the septic tank reaches this pipe, the water flows into the drain field and is filtered through the soil.

How to Reduce Sludge in A Septic Tank System – Clear Water Supply

  • As solids (sludge) builds up in the tank, the usable volume in the tank decreases. If sludge is left in a septic tank for a long time, it will compact and harden to the point where a pump truck cannot remove it. In that case, high-pressure hoses are needed to break up the sludge and clean out the tank.

Where does septic tank sludge go?

In reality, most of the faecal sludge collected from septic tanks is dumped into rivers, drains and sewers or emptied untreated into agricultural fields and low-lying areas.

How does sludge leave a septic tank?

Solution for a clogged septic system The solids settle to the bottom, where microorganisms decompose them. The scum, composed of waste that’s lighter than water, floats on top. The middle layer of effluent exits the tank and travels through underground perforated pipes into the drainage field.

Is septic tank sludge hazardous?

Toxic Fumes For starters, the sludge in your septic system is toxic. Methane gas is produced by the contents of your septic tank and are explosive. You also run the risk of falling into the septic tank which can be fatal. Along with methane, nitrate can come from a failing septic system.

How do you dissolve sludge in a septic tank?

One is to inject air into the tank to try and mix the contents and break down the solids. The more common method is to use a mechanical mixer that acts somewhat like a baking mixer where the contents are mixed until they form a slurry that can be withdrawn by the vacuum pump.

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?

What happens to poop in a septic tank?

The inlet pipe collects the water waste in the septic tank, long enough that the solid and liquid waste is separated from each other. Inside the tank bacteria from the wastewater breaks down the solid waste. These bacteria decompose the solid waste rapidly allowing the liquids to separate and drain away more easily.

Can I take a shower if my septic tank is full?

Only the water would get out into the leach field in a proper system unless you run too much water too fast. The thing to do is to run your shower water outside into it’s own drain area, but it may not be allowed where you are. Used to be called gray water system.

Can you put too much bacteria in a septic tank?

Too much of a good thing can cause problems. A septic system relies on the correct balance of bacteria to do its job. An overpopulation of bacteria can deplete the oxygen in the septic tank and turn the environment septic. A septic, septic system is one in which the ecosystem within the tank is out of balance.

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

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

Can heavy rain affect septic tank?

It is common to have a septic back up after or even during a heavy rain. Significant rainfall can quickly flood the ground around the soil absorption area (drainfield) leaving it saturated, making it impossible for water to flow out of your septic system.

What does septic sludge consist of?

Sludge: Sludge is the solid material that settles at the bottom of your septic tank to form a thick layer. The sludge is made up of non-liquid materials like soil, bones, food particles, etc. There are anaerobic bacteria that thrive in the bottom of your tank that feed off of this sludge layer.

Can a septic tank never be pumped?

What Are the Consequences of Not Pumping Your Tank? If the tank is not pumped, the solids will build up in the tank and the holding capacity of the tank will be diminished. Eventually, the solids will reach the pipe that feeds into the drain field, causing a clog. Waste water backing up into the house.

What eats sludge in septic tank?

One example of a homemade remedy is to flush ¼-½ a cup of instant yeast down your toilet. The yeast eats away at the sludge and helps loosen it, breaking it down so that wastewater can get through.

Do septic tank additives really work?

There is little scientific data to suggest that you should add bacteria or enzymes to your septic system. The United States Environmental Protection Agency reported that biological additives do not appear to improve the performance of healthy septic tanks.

How Often Are Septic Tanks Emptied, and Where Do the Contents Go?

It’s safe to assume that wherever there are many individuals who run their houses’ waste systems through septic tanks, there will be a slew of local firms that specialize in eliminating the scum and sludge that collect in the tank over a long period of time. This is a crucial service because, if too much sludge accumulates over time, it can cause overflow, which is harmful to everyone involved. Septic pumping for commercial purposes typically consists of a pump truck emptying the sludge, effluent, and scum from the tank and leaving the tank empty and ready to be refilled with fresh sludge and water.

Prior to the passage of federal legislation prohibiting the disposal of sewage sludge, waste management businesses could simply bury it in landfills.

These locations still exist, however many of them are in the process of being cleaned up (clean-up).

In certain situations, the septic contents are transported to waste treatment plants where they are combined with the stew that has been pumped in from a municipal sewer system, or they are supplied to for-profit organizations that specialize in the treatment of septage.

  1. Septage may also be placed at landfills that have been allowed.
  2. Because of the difficulties associated with properly disposing of your septic tank’s contents, septage is sometimes employed in a different way: to grow food.
  3. This application of septage has the potential to be contentious.
  4. It is expected that, when properly applied to farmland with good soil and a low water table, the soil will work as a filter in the same way as a drain field in the rear of a home with a septic tank will act as a filter.
  5. Historically, it has been recognized that methane, which is created as a waste product during the breakdown of sewage, may be utilized to generate energy.
  6. In addition, because the power produced does not burn, there is little or no pollutants emitted.
  7. One system, constructed south of Seattle, Washington, in 2004, has the capacity to generate enough electricity to power 1,000 houses.

Where Does Septic Waste Go?

There’s a good possibility that regardless of whether you have a septic tank, you don’t spend much time thinking about what happens to trash once it goes down the sink. It’s not the most pleasant thing to think about, but it’s necessary to think about where septic waste goes in order to better understand how to care for and maintain your septic tank and how to prevent it from backing up. In this article, you will learn about the significance of routine maintenance and septic tank cleaning in Cleveland, Texas.

  • This procedure, which meets the same criteria as municipal sewer systems, is intended to reduce negative environmental consequences and encourage sanitation for home and business owners while also meeting the same environmental regulations.
  • In addition to being self-contained systems that process water on site, septic systems differ from municipal systems in that they divert waste from many properties and convey it to a centralized treatment facility.
  • When wastewater enters your septic tank, it is split into three levels: sludge, effluent, and scum.
  • Sludge is the waste that settles to the bottom of the tank and must be cleaned out on a regular basis to keep the tank functioning properly.
  • Scum, on the other hand, is the grease, fat, and oil that accumulates at the top of the tank.
  • What happens to the sewage from the septic system?
  • It is possible for the tank to begin to overflow and get damaged if sludge is not cleaned on a consistent basis.
  • During septic cleaning, a contractor will arrive on your property in a tanker van and use a vacuum hose to suck out the sludge and scum from your system, removing it off your land.
  • At this facility, the waste is processed and treated in compliance with environmental rules.
  • TXAt In addition, we recognize that many septic system owners do not want to be concerned with the ins and outs of the operations of their systems.

Components of Sewage Entering and Leaving the Septic Tank

Sewage, sometimes known as “blackwater,” from a normal residential structure comprises a range of inorganic and organic components that are found in feces-fecal residue, urine, and food wastes, among other things. Dietary fibers, skin cells from the intestinal lining, bacteria (coliforms and others), organic waste and debris that may have entered the septic system, such as food scraps or debris from a garbage grinder; cellulose (dissolved toilet tissue); nitrogen; ammonia; nitrites; nitrogenate; nitrate; phosphorous; sulfate; grease First and foremost (specific sewage pathogen lists will follow), and according to several sources such as the Utah Department of Environmental Quality (Utah DEQ), “Germs that cause illness are the most common type of pollutant released by septic systems.

These germs (bacteria and viruses) have the potential to cause a wide range of human illnesses.

Blue baby syndrome, which can be deadly in newborns under the age of six months, can occur if the nitrate content in their drinking water is elevated to an excessive level (methemoglobenemia).

What are the Components of Raw Sewage

The following are properties of raw sewage, according to JantraniaGross (see sources on the Septic Systems Home Page).

  1. Overall, total suspended solids range from 155 to 330 mg/L
  2. 5-day biochemical oxygen demand (BOD) ranges from 155-286 mg/L
  3. Total coliform bacteria range from 10 8 to 10 10 CFU/100mL
  4. Fecal coliform bacteria range from 10 6 to 10 8 CFU/100mL

What are the Components of Septic Tank Effluent

On the Septic Systems Home Page, there are references to a paper by JantraniaGross, who lists the following properties of septic effluent when it leaves the septic tank (where only limited treatment has occurred).

  1. Total suspended solids range from 38 to 85 mg/L
  2. 5-day biochemical oxygen demand (BOD) ranges from 118 to 189 mg/L (this represents a 40 percent reduction from the level of the entering sewage)
  3. Total suspended solids range from 38 to 85 mg/L
  4. Total suspended solids range from 38 to 85 mg CFUs/100mL of fecal coliform bacteria (notice that there is little or no reduction in coliform bacteria above the level of coliform bacteria in the entering sewage)
  5. Ammonium-nitrogen, N 4 -N: 30-50 mg/L (note that this is significantly higher than the number for raw sewage)
  6. Ammonium-nitrogen, N 4 -N: 30-50 mg/L (note that this is significantly higher than the number for raw sewage)
  7. Ammonium-nitrogen, N 4 -N: 30 Total nitrogen concentrations range from 29 to 63 mg/L
  8. Total phosphorus concentrations range from 8 to 16 mg/L.

Nitrogen LevelsReduction in Septic Tanks, Effluent, Septic Absorption Systems

These are the average nitrogen levels found in a household septic tank, as previously mentioned in this article.

  1. Ammonium-nitrogen concentrations range from 4 to 13 mg/L
  2. Total nitrogen concentrations range from 26 to 75 mg/L.

Wastewater that has been treated by an OSS that is fully operating typically includes high levels of nitrate. Following its exit from a fully working drainfield, nitrified wastewater runs through the surrounding soil. The fate of nitrates in soil is quite unpredictable. It may be digested by bacteria, utilised by plants, or discharged into ground or surface water. It is estimated that the quantity of nitrate eliminated after exiting the drainfield ranges between 0 and 90%, depending on the site’s characteristics.

  1. Due to the rapid conversion of urea to ammonium in the septic tank’s bacteria, the nitrogen content of wastewater departing the tank, known as septic tank effluent, usually contains around 85 percent ammonium and 15 percent organic nitrogen.
  2. The median concentration is around 50 to 60 mg/l.
  3. The remaining organic nitrogen is transformed to ammonium in a process known as ammonium reduction (ammonification).
  4. It is possible that some of the ammonium will be transformed to ammonia and then lost to the environment as ammonia gas in suitably alkaline soils.
  5. It is possible for natural denitrification to occur under specific conditions, such as the presence of saturated, anaerobic, organic-rich soil under the unsaturated zone.

The great majority of conventional septic systems, on the other hand, do not have this combination of criteria. As a result, denitrification does not occur in any substantial quantity, and the final nitrogen product is mostly nitrate. – NESC Pipelines (National Energy Security Corporation) (2012)

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:

  • There are several signs of a faulty septic system, and not all of them are unpleasant odors. Any of the following signs should prompt you to seek professional help:.

Method 2: Aeration and Bio-Enzymes, Microbes and Bio-Activators

Anaerobic environments, such as septic tanks, are prevalent (without oxygen). Bacteria that devour sludge are only able to survive in an aerobic atmosphere (with oxygen). Septic tank enzymes work best when combined with an air supply and a population of bacteria that devour the sludge produced by the tank’s microorganisms.

Despite the fact that it may take many weeks, this procedure can eat up to 95 percent of the sludge in your septic tank! The most significant additional benefit is that, if you follow the schedule to the letter, you should never have to pump your septic tank again!

Taking Care of Septic Sludge Buildup

Anaerobic environments, such as septic tanks, are harmful to humans (without oxygen). Breathing air is essential for the survival of bacteria that devour sludge (with oxygen). Septic tank enzymes work best when combined with an air supply and a population of bacteria that devour the sludge produced by the tank’s bacterial population. Even though it may take many weeks, this procedure can eat up to 95% of the sludge in your septic tank! The most significant additional benefit is that, if you follow the schedule to the letter, you should never have to pump your septic tank again.

The problem with too much sludge.

Anaerobic environments, such as septic tanks, are common (without oxygen). Aerobic environments are required for bacteria that digest sludge (with oxygen). Septic tank enzymes work best when combined with an air supply and a population of bacteria that devour the sludge. Even though it may take many weeks, this procedure can eat up to 95 percent of the sludge in your septic tank! The most significant additional benefit is that, if you stick with the program, you should never have to pump your septic tank again!

Keeping the sludge down with added bacteria.

Using a bacterial supplement in the tank between cleanings is the most effective technique to keep septic sludge under control between cleanings. Bacterial additions provide a healthy dosage of additional aerobic bacteria to the tanks, which aid in the decomposition of solid waste. The hard-working bacteria keep sludge levels from increasing too rapidly and generating difficulties in the environment. For additional information on preventing sludge overflow and septic maintenance programs, please get in touch with us.

How does a septic tank work?

Pumping the tank on a regular basis eliminates sludge and scum, which helps to keep a septic system in good working order. It is possible for a well-designed and well built septic system to last for decades, or it might collapse in a matter of years. It is entirely up to you as long as you can answer the question of how do septic tanks function. Healthy septic systems are very inexpensive to maintain, but digging up and replacing a septic system that has completely collapsed may easily cost tens of thousands in labor and material costs.

It’s critical to understand how a septic tank works in order to maintain one.

Let’s take a look below ground and observe what happens in a properly operating septic system, shall we?

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.
  8. 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.

  • A layer of sludge accumulates at the bottom of the container.
  • Sludge is a mixture of inorganic particles and byproducts of bacterial decomposition that may be found in wastewater.
  • A layer of scum rises to the surface of the water.
  • Oil, fats, and grease are the primary components of scum.
  • Grease and oils float to the surface of the water and accumulate on the surface.
  • Five, a filter is used to keep most solids out of the exit pipe.
  • In addition to providing a huge space for bacteria to flourish, the drain septic field also allows treated water to seep into the earth.

It is possible for water to get into the soil and for oxygen to reach bacteria because of the gravel around the pipes. 8. Aerobic microorganisms in the gravel and soil completely decompose the waste material. The groundwater and aquifer are replenished by clean water seeping below.

  • 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

Inspections and pumping should be performed on an ongoing basis. The Sludge Judge is a device that allows you to examine the level of sludge in your own home if you are not afraid of heights. There are several internet retailers who sell it for $100 to $125. In the event that you discover that your tank is one-third full of sludge, contact a contractor to come pump it out for you.

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.

You may be able to boost the performance of your system by using a product such as RID-X to introduce bacteria into the system. 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

Reduce the amount of water you use. The volume of water that flows into your tank, particularly over a short period of time, can be reduced to avoid untreated waste from being flushed into your drain field. Replace outdated toilets with low-flow ones, install low-flow showerheads, and, perhaps most importantly, wash laundry throughout the week rather than just on Saturday mornings to save water.

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 Break Up Solids in Your Septic Tank

As a result of its ability to supply filtered water to depleted aquifers, Jim vonMeier believes that septic systems are the solution to America’s water deficit. As an advocate for septic systems around the country, he speaks at conferences, gives lectures, and appears in court. For septic system inquiries, as well as information on the operation of the septic tank, contact him through email or letter.

Ways to Break Up Solids in Your Septic Tank

Keep in mind that there is no substitute for regular septic pumpings in most cases. When the time comes to service the system, we recommend that you use a qualified technician. When we talk about breaking up solids in your tank, we are simply referring to the process of occasionally breaking up the bottom layer of sludge to ensure that everything runs the way it should. If your tank is in in need of a rapid treatment, consider one of the options listed below.

Storebought Remedies

The sludge that accumulates in your toilet tank may be eaten away by items that you can flush down the toilet. However, it is recommended that you run these goods by a septic system servicing specialist first because not all tanks are made same. Some additives can actually be damaging to your tank, thus it is critical that you only use things that are safe and beneficial to your tank.

At-Home Remedies

Likewise, while at-home remedies are frequently less expensive than store-bought alternatives, they should still be used with caution. If you want to try a DIY treatment, you may try flushing 14-12 cup of quick yeast down the toilet. In order for wastewater to pass through, the yeast eats away at the sludge and aids in its loosening, allowing it to break down.

Avoid running your washer, dishwasher, or shower for a few minutes after using a store-bought or home-made cleaning solution. This will allow the solution to do its job before being rinsed away.

Backflushing

Backflushing is the process of sucking wastewater out of your tank using a wet vacuum and then spraying it back into the tank. Most of the time, the power of the water is sufficient to break up some of the solids. Of course, if you don’t have the proper equipment, you might as well hire a professional to perform a septic tank pumping for you.

Septic Stirring

Although it may seem disgusting, “septic stirring” is merely the process of breaking up sediments using a long stick or other long implement. This treatment is often most effective for modest accumulations. Although it is possible to avoid your septic sludge from becoming overly comfortable, you must be committed to doing so on a regular basis.

Regular Tank Pumping

Of course, even if all else fails, you should continue to schedule professional pumpings on a regular basis. Removing excess particles from your septic tank is the most effective strategy to extend the life of your system and avoid costly problems from developing.

How Often Should You Have Your Septic Tank Pumped?

When your tank reaches 25 percent capacity (in other words, when one-fourth of your tank is full with sludge), it’s time to start thinking about hiring a professional to pump it out. The length of time required depends on the size of your system, the number of people that reside in your house, the total load placed on the tank, and other factors. However, in general, most tanks require professional septic pumping every two to three years, depending on the circumstances. Keep your tank’s capacity below 50% at all times.

Take the essential steps to keep your septic tank running well, and never flush anything other than toilet paper down the toilet.
