How Does Septic Tank Work With Air Compresser?

  • Aerobic septic tank systems utilize an air compressor or blower system to pump air into the main treatment tank. Here, the air mixes with the tank’s solid wastes and wastewater. This process is called septic tank aeration, and the oxygen in the air sustains the aerobic microorganisms which catalyze digestion of the waste.

What does the compressor do on a septic system?

Air pumps, also known as an aerators or air compressors, are critical to the function of an aerobic septic system. These products supply oxygen to the bacteria in the septic system.

Does septic aeration really work?

The biggest benefit to a septic tank aeration system is that studies have shown aeration can help break up waste up to 20 times faster than good bacteria alone. All in all, this means that you will have to pump your tank less frequently and you will need a smaller size leech field for your tank.

How long should septic aeration pump run?

The aerator should run 24/7 nonstop and should not cost more than 10 dollars a month to run. If you electric bill is high something else is causing it or the system is not correctly hooked up.

Should a septic tank aerator run all the time?

The aerator should run 24/7. It should continuously provide much-needed oxygen inside the septic tank of an aerobic system. The aerobic bacteria need air to survive.

Why does my septic tank have an air pump?

What exactly is a septic tank aerator? An aerator, or air pump, pushes air and oxygen into your septic system. The additional oxygen increases natural bacterial activity within the system, that then provides additional treatment for nutrients in the effluent.

How often should an aerobic septic system be pumped?

How Often Should My Aerobic System Be Pumped? There are many variables that affect how often your system needs to be pumped. This is determined by the usage of your system, and the number of people living in your home, we suggest that your system be pumped every three to five years.

Is Dawn dish soap safe for septic systems?

One of the best know is commercials for Dawn dish soap. The ability for the cleaner to disperse oil and grease is better for cleaning, as it helps to break it up. The reason these are bad for septic systems is because if you use too much they can leach out into the environment without being properly treated.

Can RIDX be used in aerobic septic system?

Rid-X is full of helpful bacteria and enzymes that work to break down things like toilet paper and grease. These enzymes will not hurt your aerobic septic system. These enzymes will not hurt your aerobic septic system.

What happens when aerator stops working?

If the aerator in your septic system stops working, your system will naturally turn from an aerobic environment to an anaerobic environment, a much slower, much less efficient environment for breaking down the solids in your system.

Why is my septic tank humming?

Humming: This is a common sound when the pump is running, but if the noise is constant, then the system might be running without actually moving any water. A common cause for this is the lack of a relief hole between the pump and the check valve, which will develop an air lock in your system.

How long does it take a septic aerator to work?

Most systems respond rather quickly, say within 4 weeks. The system will be fully functional during this period.

How do you maintain an aerobic septic system?

Here are the dos:

  1. Regularly Inspect Your Septic System.
  2. Pump Out Whenever Necessary.
  3. Be Water-wise.
  4. Use Licensed, Certified Companies.
  5. Flush Solids Down the Drains.
  6. Pour Harsh Chemicals in Your Toilets.
  7. Park Cars or Trucks on Your Drainfield or Reserve Area.
  8. Add Septic Tank Additives.

Septic Air Pumps – The Lifeline of Your Aerobic System

An blockage in the line produced by a buildup of pressure between the item and the inner circle of the pipe. A diaper that becomes trapped in the sewage drain line is an example. There is just too much diaper to be able to fit through the line at the same time, An blockage created by an accumulation of material at the site of a flaw in the pipe’s construction. It is possible that the flaw falls into a variety of distinct categories. An intrusion (barb, pipe fragment, root) in the pipe that may “collect” debris is described as follows: A “belly” in the pipe is formed when the slope of the pipe is so small that gravity is no longer able to carry waste particles away from the pipe.


Aerobic Treatment Systems are a type of wastewater treatment that is technologically sophisticated. They are often composed of a single many chambered tank or a number of tanks with a variety of stages. These stages are often comprised of a solids collection tank (trash tank), an aeration chamber, and a settling tank, among other things. Even more advanced models include an additional four-stage disinfection stage (using chlorine or ultra-violet) that may also serve as a pump chamber. An Aerobic Treatment System is capable of processing waste and discharging water that is more than 98 percent clean and odorless.

Conventional septic systems are typically comprised of a single or two compartment tank that collects big particles while allowing liquids to pass through to a secondary treatment system for further treatment (drain field, mound system, sand filter, etc.).

You’re probably asking what all of this has to do with air pumps now that you’ve gotten a quick introduction of the two primary types of sewage systems.


On an aerobic system, the air pump can be referred to by a variety of names, among which are the following: Septic Air Pump, Septic Aerator, Aerator Pump, and Compressor are all types of septic equipment. For the purpose of simplicity, I’ll refer to it as a Septic Air Pump throughout this post, and I’ll be referring to the small box in your yard that pumps air into your septic tank rather than any of the other titles I gave above.


In many ways, the septic air pump is the lifeline of your aerobic system. It is impossible for the system to function properly unless the air pump is operating properly. Two distinct functions serve as the basis for the air pump’s operation. Firstly, the air pump introduces oxygen into the water, allowing Aerobic bacteria to colonize and survive in the water. The Aerobic bacteria in the tank are responsible for completely decomposing all of the waste. When compared to the anaerobic bacteria present in a traditional septic system, these bacteria are far bigger and more efficient at digesting waste.

Second, the air pump provides an action in the tank that breaks down big solids into little particles, making it very simple for bacteria to cling to and consume the waste, resulting in a cleaner tank.

It is the absence of a secondary treatment system behind your aerobic system, as is the case with a traditional anaerobic septic system, that poses the greatest risk of this occurring.

Raw sewage dumping into a ditch, lake, or pond, or being sprayed on your grass, as you may be aware, is not a nice thing. For this reason, it is critical for the operation of your system that the air pump is operational.


In many ways, your septic air pump is the lifeblood of your aerobic system. Without the air pump, the system will not function in the manner for which it was intended. Actually, the air pump serves two distinct functions. Firstly, the air pump introduces oxygen into the water, allowing Aerobic bacteria to flourish and survive. The Aerobic bacteria in the tank are responsible for completely decomposing all of the trash in it. Anaerobic bacteria present in a traditional septic system are significantly smaller and less effective at digesting waste than aerobic bacteria.

If the air pump in your aerobic system stops operating, the system will begin to revert to anaerobic mode over a period of around 2 weeks.

Because once the aerobic system becomes anaerobic again, the effluent will be more similar to raw sewage, rather than the clear odorless discharge that is currently produced.

Therefore, the air pump’s operation is critical to the overall operation of the system.

Typical Aerobic Septic Air Pump Capacity Ratings

The output of aerobic septic air pumps is measured in cubic feet per minute (CFM) or liters per minute (LPM) of air flow. A common septic aerator pump may provide 5 CFM (80 LPM) of air output, which is normal. The normal flow rate of septic air pumps for residential septic systems is around 2 to 8 cfm, or approximately 40 to 200 LPM of air flow rate. There is, in fact, something difficult to grasp about these evaluations. In fact, when the output is restricted, as in a septic tank, a septic air pump rated for 100 LPM air output at “open flow” (or un-restricted output) would actually give a lower flow rate than when the output is unrestricted.

In other words, if you put an air pressure gauge on a tee in the pump’s output air line, which runs between the pump’s output port and the aerobic septic tank diffuser, you WOULD observe some air pressure (with the necessary fittings, of course – you can’t just hold the gauge in that spot).

Question: How do I size the correct aerator pump for my ATU?

11/5/2015 Josh asked:How can I determine the proper size of an aerator pump for my ATU? My system has a capacity of 600 gallons. We have 5 individuals living in our home, with visitors occasionally numbering as high as 10. Is it necessary to have two pumps, or may I operate them in parallel?

Reply: aerobic septic pump sizing table

Josh I’m sorry, but I don’t have an answer to your very fair question. All of these factors add up to “consult with your aerobic septic designer or aerobic pump sales or supplier contact” when determining the necessary aerator pump size or cubic feet per minute of air supply required:

  • The intricacies of how your particular system was constructed, which vary depending on the company and model you have
  • Average and maximum daily wastewater flow into the septic system
  • The size of the septic tank
  • The design of the actual aerator or bubbler
  • The distance from the aerator pump tank
  • The size or diameter of the piping
  • The length and limits such as the number of elbows
  • And other factors. because of the depth of the bubbler, which is a measure of how far the aerobic pump must drive air down and hence how much pressure the aerobic pump will meet

Aerobic Septic System Air Pump Specifications

2017/09/21 In response to Dexter’s question, “How do you check the air pressure on a pump to ensure that your diffuser is not clogged?” and “What should the air pressure measurement be?”

Reply: aerobic septic air pumps are rated as open flow in CFM or LPM but air pressure readings can be diagnostic

Thank you for your inquiry, Dexter. If you’re wondering what the optimal air output for an aerobic septic system air pump should be, there isn’t a single “correct answer” (also referred to as septic aerator pump or septic diffuser pump, or septic air pump or septic “compressor” pump). This is because, based on the size of the septic tank and the amount of waste produced on a daily basis, the pump model will be selected to meet a certain output rate. A septic air pump’s rating is often determined by water pressure rather than air pressure, because the pump’s output end is meant to be exposed to water and ultimately the atmosphere.

Another way to say it is that, although though the aerobic air pump has a pump operating air pressure capacity, the pump output is often given by the manufacturer as “open flow” capacity in cubic feet per minute (CFM) (or LPM).

That is why I stated that it is difficult to quantify.

What Air Pressure Could be Seen at a Septic Air Pump?

Using the Hiblow HP-80 aerobic septic air pump as an example, the manufacturer rates the pump’s maximum airflow at 4.2 cfm (119 LPM) when the pump is operating at 0 p.s.i., and the rated air flow will be LOWER – about 80 LPM (2.83 cfm) when the pump is operating at the rated pressure of 2.13 p.s.i. when the pump is operating under actual installed conditions. As a result of the fact that unique septic air pump specifications will change among manufacturers’ brands and models even before the pump is installed, you should make a note of the precise brand and model of the pump you are using.

  1. The pressure range will most likely be between 1.5 and 5 psi.
  2. To put it another way, if we went underwater (I don’t want to swim beneath sewage) and went down to 30 feet, we would be at one ATM of pressure, which is approximately 14.6 psi more pressure than being on the surface of the ocean at sea level.
  3. 1/6 of 14.6 psi is equal to 2.4 psi.
  4. If the pressures at our magic Tee, which we inserted in the air line, were lower than the manufacturer’s specifications, the pump (or the air line) is most likely malfunctioning (or there is an air leak).

If we notice pressures rising over what the manufacturer has specified, it is possible that the diffuser has become blocked. However, skipping the tee and the pressure gauge and simply looking for bubbles is more convenient.

Question: what are the aerobic septic pump tubing or piping distance limitations?

The following illustration depicts the drop in net air flow or CFM as a function of increasing pressure in the delivery system over zero limitations at the pump output for the Secoh EL-series aerobic pumps: CFM or LPM performance curves for the Secoh EL-series aerobic pumps. – derived from Secoh, which is discussed in further detail below. 2019/02/18 Bill Grambsch wrote: “I’d want to relocate my Aeration air pump 50 feet away from my septic tank,” he explained. I have 50 feet of 1/2-inch PVC tubing as well as the electricity to run the air pump.

Do you have any difficulties or concerns?

Is there any reason why I cannot add a 50-foot air hose to the system to eliminate the noise?

Reply: keep aerobic air pump tubing or pipes as short and straight as possible or risk inadequate aerobic treatment and system failure

Bill, Thank you for presenting such a thought-provoking question: What is the impact of distance on the performance of aerobic septic tank aerators? or What is the maximum length or distance of tubing that may be used with an aerobic septic aerator pump? The Secoh EL-80 septic pump is available in a variety of versions with air supply rates ranging from 2.83 CFM to 4.23 CFM. The pump is rated as Air Flow: 80LPM or 2.83 CFM to 4.23 CFM Open Flow. The performance curves for Secoh aerator pumps given below (which were taken from the company’s sales brochure) clearly demonstrate that as the pump’s “PSI” increases, the flow rate declines.

It is vital to comprehend the concept of “open flow.” It is possible to measure open flow at the pump’s exit since there is no resistance on the pump’s side.

The following is how septicsolutions, a vendor of septic aerators, puts up the problem: It is customary for the size of the air pump to be dictated by the volume of the tank, the kind of air diffusers installed in the tank, and the number of GPD (Gallons Per Day) that the system is meant to treat.

Keep an eye out for: In practice, this implies that, assuming that your septic aerator pump was correctly sized and installed in the first place, you should not relocate it more than 50 feet away without first contacting with Secoh or the firm who built and installed your aerobic septic system.

  • Keep in mind that if the air flow rate, volume, duration, or CFM / LPM in an aerobic septic tank is insufficient, the expense might be crippling.
  • I’m sorry for not being able to provide a more precise response, such as – yes, if you use 3/4″ tubing – but, like Secoh, from my vantage point in central Mexico, I cannot see your aerobic septic installation and so have no more information about it to share with you.
  • Septic Solutions is located at 314 Center St.
  • According to Secoh, the following pipe requirements are necessary for their air pumps: PIPING: Choose tube sizes, lengths, and attachments carefully to ensure that pressure loss is kept to a minimum.
  • Using tubing with a diameter that is greater than the port on the device (inside diameter min.
  • There are no elbows and the bends are of great radius.
  • Diffusers for aeration with low air loss – For further information, please contact Secoh EasyPump at 50 West Drive, Melbourne, Florida 32904 (phone: 321-253-1999, toll-free: 1-800-225-4498, or email: [email protected]). is the website or online store for Secoh. was the original source, which was obtained on February 18th, 2019.

Other aerobic septic system aerator-air pump checks you can make

Make sure of it.

  1. The fact that the aerobic aerator pump is operational
  2. Aerator pump is providing air to the septic tank as shown by the appearance of air bubbles at the tank top inspection port
  3. This includes making sure that the aerator pump tubing or pipe is not restricted, bent, kinked, or clogged with debris. That you are completing the periodic maintenance on your aerator pump in accordance with the manufacturer’s recommendations – samples of aerobic pump maintenance and installation manuals are provided below
  4. When the pump stops operating or is turned off, certain septic air pump types incorporate an alert feature to notify you of the situation. The fact that you may leave your aerobic system without its aerator means that the system is not operating well, it is not treating sewage effectively, and the system might fail in a matter of days
  5. This is a convenient feature.

Septic Air Pumps – Wholesale Septic Supply

Overview Air pumps, also known as aerators or air compressors, are key components of an aerobic septic system’s operation and performance. The bacteria in the septic system benefit from the use of these goods because they provide them with oxygen. These equipment must be present and in correct working order in order for the bacteria in an aerobic system to survive. Otherwise, the system will no longer be able to successfully treat wastewater. Septic aerators are available in a variety of configurations, each with its own set of advantages.

  1. For the ordinary septic system, those aerators are a dream come true.
  2. Rotary vane air compressors, on the other hand, are significantly better suited for huge systems.
  3. Sewage air compressors are often placed close to the control panel for the septic system in which they are installed.
  4. If the air compressor’s air pressure drops below a certain level, the pressure switch will sound an alert.
  5. The average lifespan of a septic air compressor is three years before it has a breakdown.

To its advantage, replacement parts and repair kits are readily accessible for all of the main aerator manufacturers. When compared to acquiring a new aerator, these kits can be significantly more cost efficient.

Is My Aerobic Septic System Supposed to Run All the Time?

Overview Air pumps, also known as aerators or air compressors, are key components of an aerobic septic system’s operation and performance. In the septic system, these chemicals provide oxygen to the bacteria. These devices must be present and functioning properly in order for bacteria in an aerobic system to survive and for the system to be efficient in treating wastewater. It is possible to purchase a variety of varieties of septic aerators, each with its own set of advantages. The linear diaphragm aerator, for example, is the most popular form of septic air compressor.

  1. The materials used are durable and simple to reassemble.
  2. The reason for this is that rotary vane aerators can flow far more air than other kinds of septic air pumps.
  3. Another common feature is the use of an air line to link the aerator to a pressure switch located on the control panel.
  4. A septic aerator is typically good for about a year.
  5. For all of the main aerator brands, replacement parts and rebuild kits are readily accessible.

“Modad Septic Tank Aerators, Air Pumps, BlowersAir Compressors?”

The terms used above to describe the device that supplies air to the modad treatment plant are interchangeable. a. The most correct word for this device is “Air Pump,” and its role is to create a continual flow of air to the modad aeration system through a 1/2-inch PVC pipe that connects to the first chamber of the modad treatment facility. Upon entering this chamber, the pvc pipe is directed downward for approximately 5.5 feet, to within inches of the tank’s bottom, and then branches out to form a tee with numerous drilled holes, much like an aquarium aerator, to allow the air from the air pump to diffuse through the liquid sewage from bottom to top.

“Why Do Septic Tanks/Sewer Treatment plants Need Air Pumps And Aeration Systems When Septic Tanks Don’t?”

Air pumps and aeration systems are essential in all contemporary commercial and residential waste water treatment facilities (MODADS) in order to meet regulatory requirements. So, what is the rationale behind this requirement? What is the benefit of this? The reason for this is that wastewater treatment facilities equipped with an aeration system produce effluent that is around 95 percent pure water, whereas the traditional septic tank, which does not have aeration, produces water that is only 45 to 65 percent clean.

However, it is a really strong conclusion for what appears to be a relatively basic add-on to the system. Consider the variations in the breakdown of sewage waste that occurs in a septic tank and a modad treatment plant (with aeration) in the following paragraphs.

“The Septic Tank Without An Air Pump and Aeration System”

The “septic tank” is a cylindrical or square tank with only one chamber, which might be circular or square. The waste water is broken down in the septic tank by anaerobic bacteria that are found naturally in the environment. They are referred to as “anaerobic” because they breakdown sewage waste in the absence of oxygen (oxygen). The fact that these identical anaerobic bacteria are already at work in our digestive system long before they reach the septic tank should come as no surprise. (Wow, what a beautiful concept!) The anaerobic process in a septic tank breaks down sewage by hydrolysis (adding water), which starts off fermentation, which creates acetic acid, hydrogen, and carbon dioxide at the beginning of the process.

  1. Of course, we, too, emit the same gases that they do as a result of the same activities.
  2. So, since all of this harmless gas is being released, then the end result must be a clean water discharge.but this is far from the case.
  3. Acetic acid, ammonia, and hydrogen sulfide gas are all present in the water as a result of this addition.
  4. Can you image what massive volumes of water like this would do to any species that were able to survive in fish, for example?!
  5. You guessed it.because all of the organic debris sinks to the sludgy bottom and initiates the anaerobic fermentation process.
  6. The acetic acid present in the water causes the tannin (brown) pigment to be leached from the plant material as it decomposes, resulting in the hue of the water.
“The Waste Water Treatment Plant With An Air Pump and Aeration System”

The Modad waste water treatment facilities, which include an air pump and an aeration system, are presently being used to replace all septic tanks in the state of Mississippi. The arrangement seen in the figure below is common for these plants. This tank has two chambers (although some tanks have three); the first is the Aeration Chamber, where air from the Modad air pump is directed to the bottom of the tank through a 1/2′′ pvc pipe that terminates there and releases bubbles up through small holes drilled in the pipe.

  • This is all done in order to stir and fully aerate the waste water that is being received.
  • Let us now track the route taken by the sewage on its way in.
  • In order to proceed, it is necessary to realize that the Modad Treatment Plant, like the septic tank, is an overflow system that must be avoided.
  • The input line that you see going into the tank from the home is set up approximately 4 inches above the level of the waste water in the tank, as you can see in the photo.
  • By utilizing an overflow, this helps to keep the waste water level consistent.
  • As you can see, the treatment plant is always full, but it is also in a permanent condition of water moment due to the ongoing inflow of sewage water.
  • Organic particles, oils, and greases in the sewage will float to the surface and remain there until they are digested by aerobic bacteria, which will then sink to the bottom.
  • Keep in mind that every 3 gallons that enters the Modad tank equals 3 gallons that exits the Clarifier chamber output line.
  • What are the outcomes of this experiment?

The outflow water will also be oxygenated, which means it will not be detrimental to aquatic species as they exit the tank.

“It Makes Sense To Have A Waste Water Treatment Plant And To Make Sure Your Air Pump, Aerator Is Working Properly”

We have learned from the outcomes of the Waste Water Treatment Plant in Mississippi that it is wise to check that your Modad air pump and aerator are in correct operating order before using them. What methods do we use to do this, and what issues do we have with Modad air pumps, aerators, and blowers?

“What Types of Air Pumps-Aerators-blowers are there and what is the best Type of for your Modad Waste Water Treatment Plant?”

The “Mixer Aerator” and the “Rotary Blower” are two of the most ancient forms of aeration devices, both of which are seen below: Aerator for the Mixer Blower with a rotary motion It is a great aerator that produces more air than any other form of aerator, but it, like the mixer aerator to the right, suffers from the problem of having huge electric motors that consume a lot of power and are thus expensive to run on a continuous basis.

  • As a result, they are typically set on a timer to conserve energy and run multiple on and off cycles throughout the day to save money.
  • If you still have one of these two types of aerators in your home, it is likely that they are no longer in operation as well.
  • As a result, the vast majority of Modad sewage treatment plant manufacturers have now certified the newest form of air pump aerator known as the “Linear Diaphragm Air Pump” (pictured below) for use in their individual treatment plants, which may be found below.
  • It operates in the manner depicted in the accompanying animation.
  • After this period, the plastic diaphragms get worn and need to be changed, which may be accomplished with a relatively simple kit.
  • Ordinarily, the amount of air pumped at between 2 and 4 psi pressure is specified in Liters per minute, which is the volume of air pumped per minute.
  • The following diagram illustrates the dimensions and weights of the various-sized pumps:
“The National Sanitation Foundation (NSF) And Certification of Aerator, Air Pumps For Modad Sewer Treatment Plants in Mississippi”

Clearly, the Linear Diaphragm Air Pump is the most effective contemporary air pump for aeration in residential wastewater treatment facilities in Mississippi, as seen above. According to NSF regulations, the National Sanitation Foundation (NSF) must approve each make and model of Modad sewer treatment plant before it can be used “legally.” The NSF is the governing body that certifies which size, make and model of air pump may be used “legally” for each make and model of Modad sewer treatment plant.

It is recommended that you examine the relevant State’s laws and requirements before proceeding.

As a result, if you do not intend to sell your home within five years or so, your decision to go with a less expensive pump may be justified.

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?

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

Septic systems that have been correctly planned and constructed require just occasional ‘pumping’ to remove the sludge and scum that has built up inside the tank.

However, if you don’t understand how a septic tank works, you may unintentionally hurt or even destroy the system.

  • 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

If your septic system becomes clogged and you find yourself having to clean the filter on a regular basis, you might be tempted to simply remove the filter altogether. Hold on to it. Solids, wastewater, and scum are separated into three levels in septic tanks, which allows them to function properly (see illustration above). Solids sink to the bottom of the container, where microbes breakdown them. The scum, which is made up of trash that is lighter than water, rises to the surface. In the drainage field, the middle layer of effluent leaves the tank and goes through an underground network of perforated pipes to the drainage field.

  1. Keep the effluent filter in place since it is required by your state’s health law.
  2. Waste particles might flow through the filter and clog the perforated pipes if the filter is not used.
  3. Your filter, on the other hand, should not require cleaning every six months.
  4. A good chance is high that you’re flushing filter-clogging things down the toilet, such as grease, fat, or food scraps.
  5. A garbage disposal will not be able to break down food particles sufficiently to allow them to flow through the septic tank filtration system.
  6. Plastic items, disposable diapers, paper towels, nonbiodegradable goods, and tobacco products will clog the system if they are flushed through it.

For additional information on what should and should not be flushed down the toilet, contact your local health authority. More information on removing lint from your laundry may be found here.

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

Make sure the pipes are clean and free of debris. A rotating pressure washer, used by a contractor, can be used to clean out the drain septic field pipe. The cost of “jetting” the pipes is around $200. Chemicals should be used to clean the system up. A commercial solution (not a home-made product) that enhances the quantity of oxygen in the drain field should be discussed with your contractor before installation. Septic-Scrub is a product that I highly suggest. The average cost of a treatment is between $500 and $1,000.

The procedure of “terra-lifting,” which involves pumping high-pressure air into several spots around the drain field, is authorized in some jurisdictions.

This might range from less than $1,000 to more than $4,000, depending on the circumstances.

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.

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.

3 Tips to Keep Your Aerobic Septic System Strong

1. Keep your aerator in good condition. The advantages of an aerobic septic system are derived from the microorganisms that are utilized to break down waste. A typical system comprises anaerobic bacteria, which can live in the oxygen-depleted environment of a septic tank and treat the waste produced. Aerobic septic systems include aerobic bacteria, which are microorganisms that require a constant supply of oxygen in order to function properly. The aerator, which is a component of an aerobic septic system, is responsible for supplying this oxygen.

  1. If the aerator stops working, the bacteria will not be able to acquire enough oxygen to survive.
  2. Aerators die for a variety of reasons, the most prevalent of which are as follows: The first problem is caused by blocked air diffusers.
  3. Furthermore, the blockage causes a significant amount of pressure within the aerator itself.
  4. Insect infestations are the second most prevalent reason for a failed aerator, behind overheating.
  5. Eventually, when the nest has grown sufficiently, it will induce a short, which will render the aerator non-functional.
  6. Secondly, never use chlorinated pool waterAerobic septic systems are distinguished by the presence of a unique component known as the chlorinator, which disinfects waste water before it is discharged into your yard.
  7. On a semi-regular basis, it is necessary to replace the chlorine in the chlorinator with fresh chlorine.

These pills are quite similar to ones that are commonly seen in swimming pools.

Trichlorisocyanuric acid is included in the tablets used to treat swimming pools.

Swimming pool pills do not dissolve rapidly enough, nor do they have the chemical strength required to disinfect septic system waste water.


Two tanks are used in an aerobic septic system.

Aerobic bacteria break down solid waste into sludge in this environment.

The liquid is pumped from the pump tank to the chlorinator, where it is discharged onto your grass.

However, a system that is ill or poorly managed may not be able to break down liquid waste to the extent that it should.

Clarity testing may be performed by a specialist to assess how clean the water in your pump tank is and how well your system is functioning.

More information on having a clarity test conducted on your aerobic system may be obtained by contacting Walters Environmental Services, a leading septic service provider. : Septic Air Pump
