What Causes Cement To Corrode In Septic Tank? (Best solution)

Corrosion in tanks occurs due to a process called microbially induced corrosion. There are three phases to the process where the pH of the concrete is first reduced due to the slightly acidic nature of H2S, then microbes can attach to the concrete, and finally sulfuric acid is generated causing accelerated corrosion.

  • One possible cause is lack of ventilation. When the septic tank is improperly ventilated, sulfuric acid forms and breaks down the concrete at the baffle. Sometimes corrosion in concrete tanks occurs even with proper ventilation.

Why do concrete septic tanks fail?

In the case of a concrete septic tank, it can deteriorate and fail from the damage caused by the hydrogen sulfide gas and subsequent chemical rections that are a byproduct of anaerobic bacterial respiration.

What is the life expectancy of a concrete septic tank?

Inspectapedia estimates that a steel tank baffles will rust out in 15 to 20 years and may collapse if driven over, but a concrete tank will last 40 years or more as long as the wastewater is not acidic. It’s important to consider the life expectancy of a drain-field, too.

Do concrete septic tanks go bad?

A concrete septic tank can last 40 years to nearly indefinitely, though poor quality concrete or acidic ground water may result in deteriorated baffles or tank components. A conventional septic drain field has a varying life as a function of the soil percolation rate, drainfield size, and usage level.

How do you maintain a concrete septic tank?

Follow these tips to maintain your septic tank system and keep it working properly:

  1. Once you’ve found your septic tank, record the location for future reference.
  2. Have your septic tank inspected regularly.
  3. Pump out your septic tank every three to five years.
  4. Use biodegradable toilet paper that breaks down easily.

What are the signs that your septic system is failing?

The first signs of a failing septic system may include slow draining toilets and sinks, gurgling noises within the plumbing, sewage odors inside, continuing drainage backups, or bacteria in the well water.

Can you repair a cement septic tank?

To repair large cracks, your septic repair technician will pump out and clean the tank. They will let it thoroughly dry and then apply concrete crack filler to the cracks. Finally, once cured, then the tank can safely be used again.

Does 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.

How often should you pump your septic tank?

Inspect and Pump Frequently The average household septic system should be inspected at least every three years by a septic service professional. Household septic tanks are typically pumped every three to five years.

How do you tell if your septic tank is full?

How to tell your septic tank is full and needs emptying

  1. Pooling water.
  2. Slow drains.
  3. Odours.
  4. An overly healthy lawn.
  5. Sewer backup.
  6. Gurgling Pipes.
  7. Trouble Flushing.

What is the most common cause of septic system failure?

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

What will ruin a septic system?

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

Can a septic system last forever?

How long does a septic system last? On average, a new septic system will last for 20-30 years. Soil quality – the quality of soil will determine how durable your septic tank is. For instance, acidic groundwater can corrode a concrete septic tank.

How do I increase bacteria in my septic tank?

Flush a packet of brewer’s dry yeast down one toilet on the bottom floor of your house once a month. The yeast will help add “good” bacteria to your septic tank and break down waste.

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.

How can I increase bacteria in my septic tank naturally?

Homemade Septic Tank Treatment The ingredients required for this natural solution are the following: Water, Sugar, Cornmeal, and Dry Yeast. To concoct this mixture, first start by boiling roughly a half gallon of water. Add in 2 cups of sugar. The sugar will act as the first food your bacteria will eat!

Understand the Causes of Concrete Tank Corrosion

The white fiber reinforcements in a failing septic tank are beginning to peek through. After reading previous comments on excessive corrosion around outlet baffles on concrete septic tanks, I decided to speak with one of the septic professionals who remarked that he was also finding excessive corrosion around the outlet baffles but also in the distribution box. An effluent screen was installed at the output of the system. The degeneration of distribution boxes, as well as deterioration at the outlet end of septic tanks, has been reported to me by a lot of people all throughout the nation (mainly from Colorado, New Mexico, and Arizona up until now).

The other significant potential associated with concrete distribution or drop boxes is that the quality of the concrete pour does not fulfill the standards for sulfur resistance, which is a significant risk.

It is possible for tanks or distribution boxes to get corroded in two different ways.

Other views and thoughts about the reasons of corrosion have been voiced by experienced service providers, including:

  • Construction of the tank
  • Incorrect mix and additives in the concrete
  • Poor concrete mix at the factory
  • Water softeners releasing their waste into the tank
  • Water from a contaminated well

Construction of the tank; incorrect mix and additives in the concrete; poor quality concrete at the factory; Softeners that discharge into the tank are referred to as “hard water softeners.” The well water is of poor quality.

Spotting Septic Tank Corrosion

Septic tank corrosion may only be detected by peering into the tank, which is normally done during periodic septic tank cleaning or septic system inspections – the tank’s lids must be exposed and removed in order to do so. Posted on

What causes corrosion?

When it comes to what causes septic tank corrosion, there are a variety of theories.


Natural bacteria in septic tanks produce hydrogen sulfide gas, which is harmful to the environment (causing the rotten egg smell in sewage). In natural conditions, this gas remains latent in septic tanks unless some type of agitation is added. During the turbulence creation process, the gas is freed and floats freely within the tank’s air space (see figure). Another type of bacterium, called thiobacillus, transforms the gas into hydrosulfuric acid, which attacks and dissolves concrete.

Airtight compartments

The separating wall in the septic tank does not always contact the top of the tank, allowing gasses from the second compartment to leak back through the first compartment and back through the plumbing vents in the home.

This is called a backflow. This separating wall, which may stretch all the way to the top of the tank, might obstruct any gas escaping from the second compartment.

Water softeners

We have noticed corrosion on several tanks that do not have water softeners connected to the system, which leads some to assume water softeners are harmful to the tanks. Other ideas include the use of substandard concrete mixtures and/or the chemistry of the water.

What are the effects?

We have witnessed corrosion on several tanks that do not have water softeners attached to the system, which leads some to assume water softeners are having an impact on them. The use of substandard concrete mixtures and/or the chemistry of the water are two other possible explanations.

It’s not always old tanks

We have noticed corrosion on numerous tanks that do not have water softeners attached to the system, contrary to popular belief. Other ideas include the use of substandard concrete mixtures and/or the chemistry of the water used.

Can I prevent corrosion?

Despite the fact that studies have been inconclusive, pumping the tank on a regular basis may be the most effective preventative precaution a homeowner can take to protect their house. The importance of having your septic tank cleaned on a regular basis cannot be overstated. The business that pumps your tank should inspect it for concerns like as corrosion.

Research Looks for Ways to Slow Septic Tank Deterioration

He is an emeritus professor at the University of Minnesota Department of Soil, Water, and Climate and the winner of the Ralph Macchio Lifetime Achievement Award, which recognizes outstanding contributions to the pumping industry. Jim may be reached at [email protected] with questions concerning septic system care and operation. As I said last month, advanced corrosion in concrete sewage tanks has been the subject of much controversy in the industry for quite some time now. This corrosion has long been linked to hydrogen sulfide gas, which has been recognized as the cause (H2S).

  • Aside from that, minor amounts of the gas can be created by organic material in the piping leading to and from the storage tanks.
  • Microbiologically-induced corrosion (MIC) is the process that causes corrosion in storage tanks.
  • Answers to inquiries about why it happens and how to prevent it have mostly revolved around the fact that there is a lack of appropriate ventilation to allow gases to escape from within the tank’s boundaries.
  • Tanks and pipes are often vented back into the home through the house sewer and out the roof stack in gravity-flow systems.
  • According to certain studies and a large amount of service provider feedback, it appears that the H2S accumulations are not only caused by the gas created in the tank, but also by the gas that accumulates downstream from the tank outlet.
  • It also contributes to the understanding of why the distribution boxes in some systems have advanced corrosion.
  • The National Precast Concrete Association has conducted research on concrete mixtures, new additives, and sealers, among other things.

The National Precast Concrete Association is conducting study on this problem, as I noted in last month’s column.

The first featured corrosion in a pump tank, which occurred both at the entrance and at the point where the pressure line exited the tank.

For me, this was intriguing since I had previously believed that all pump tanks or chambers should be equipped with baffles on the intake side, with the explicit objective of reducing or eliminating turbulence in the tank.

An input baffle was more likely to be required in the case where the pump station was located in the second chamber of a storage tank.

I would recommend everyone to double-check their codes and specifications to ensure that an inlet baffle is stated.

The concentrations of H2S in this location were around 100 parts per million (ppm).

The weep hole should be located in a location where it will not spray the tank’s side and at a location where turbulence may be reduced.

The H2S values that were measured were 700 ppm or higher.

This shows that the gas was re-entering the atmosphere from the drainfield area.

As I previously stated, as our systems have gotten more complex, it has become necessary to include extra venting in order to avoid the possibility of H2S gas accumulations, which may result in corrosion of the system components.

I’m confident that we haven’t heard the last of this subject, but it appears like we may have a few more answers than we have in previous years.

Wastewater Industry Seeks Solutions to Septic Tank Corrosion Caused by

Get articles, news, and videos about Onsite Systems delivered directly to your email! Now is the time to sign up. Plus, there are Onsite Systems. Receive Notifications Is it possible for my septic tanks to degrade as a result of a lack of oxygen? This was one of a number of inquiries that a homeowner had recently asked about his septic system, and it was answered in part by the following: In light of the fact that our sector deals with tank corrosion and has ongoing conversations regarding the most prevalent causes and solutions, this is an intriguing subject to pose.

When it comes to the corrosion and degeneration of the top of concrete sewer pipes, some engineering publications used by wastewater specialists use the phrase “crown rot” to explain what is happening.

Sulfate bacteria

For those of us who come from an agricultural background, I thought this to be particularly intriguing because “crown rot” is the word used to describe a form of plant disease caused by a fungus that can be quite destructive to crops. The results of my quick poll revealed that I was unable to identify whether wastewater operators or plant pathologists were the first to refer to the phrase. There is a strong resemblance between the two problems in that crown rot damages the growth point at the very top of the plant, whereas concrete corrosion is a problem in septic tanks because it targets the lid and the top of the outflow baffles.

  1. Despite the fact that the answer is no, oxygen does play an important function.
  2. This is true in this circumstance, as it is true in so many other elements of our sewage treatment systems.
  3. Some hydrogen sulfide gas escapes into the atmosphere above the wastewater treatment plant.
  4. As a part of the hydrogen sulfide gas and oxygen gas from the air above the sewage dissolves into these stationary droplets, they serve as a home for sulfur oxidizing bacteria to thrive in the environment.

Because hydrogen sulfide gas is heavier than air, it would accumulate at the low points in the tank that would be near the exit, where the concentration of gas will grow high enough to cause the conversion of hydrogen sulfide gas to sulfuric acid.

Leads to collapse

Furnic acid begins to interact with the concrete, altering the structure of the calcium hydroxide in the concrete, causing pressure to build up between the neighboring concrete and aggregate particles, resulting in spalling of the surrounding concrete and aggregate particles. The weakening concrete will eventually deteriorate to the point that it will crumble to the ground. This is why, in a half-joking fashion, I like to point out in workshops that if you see any degradation, you should move back off the hood of the vehicle.

  1. 1.
  2. Providing enough sewage ventilation can help to lessen the amount of hydrogen sulfide gas in the atmosphere while also drying off exposed sewer tops.
  3. In the septic tank environment, increasing the flow rate is not appropriate because we want the sewage to have a long enough detention period to allow sediments to settle.
  4. The answer for our environment is to ensure that the tank is adequately vented back to the atmosphere through the house-plumbing stack, so that hydrogen sulfide does not accumulate and grow to levels where sulfuric acid is created.
  5. In general, sulfate-reducing bacteria are found in naturally occurring quantities in wastewater, as well as in our septic tank environment.
  6. It can also cause the contents of the septic tank to become acidic, which reduces the capacity of the organisms in the tank to break down the particles in the tank.
  7. Consequently, if you operate in a location where sulfates are naturally present in large concentrations, you may have greater difficulties.

Venting may help

Because of a distinct set of mechanisms, soils that naturally contain high levels of sulfates can also be corrosive to concrete. Tanks can degrade from the exterior if sulfate-resistant concrete is not utilized in their construction. For the final point, I’ve been receiving a lot of reports regarding concrete distribution boxes that are exhibiting signs of severe deterioration. Service providers have reported that this is happening more frequently today than at any other time in the past.

One step we might wish to take is to increase the amount of ventilation available in our system. As we add items to the system, such as effluent screens and other items, we may find that we are interfering with the venting process, which will result in some extra complications.

Septic Tanks

Author:Septic Tank Yank (CO)Hamilton,When you consider the cost of replacing the entire cover of the septic tank, not just the access hole lids, well then it is more cost effective to replace the entire septic tank.Keep in mind that the concrete in the walls of the tank above the water level has also been attacked by the sulfuric acid and is slowly crumbling away.So even if you have a new cover poured, the concrete in the walls of the tank is not going to last very long.It is akin to rearranging the deck chairs on the Titanic.I have included with this response another response that I wrote in answer to a fellow whose screen name was “Dumbdad” who was facing a similar problem.If you follow the advice given to Dumbdad, you too can have a septic system that lends itself to easy maintenance and a system with a very long service life.With the use of modern materials, a proper system design, careful installation, and annual maintenance, a septic system with an infinite service life is possible.*****************************************************************Author: Septic Tank YankDumbdad, sure sounds to me like the septic man is right. If you decide to have the leach field replaced, consider installing 2-half sized leach fields equipped with a 4-inch, NDS brand diversion valve. Cover the valve riser with a 10-inch round irrigation valve box to allow for easy access. The top of the box is set at the final grade elevation. The valve will allow the alternation of flow to the fields. Use half the field for 1-year while the other half rests. Turn the valve annually on the 4th of July, SEWAGE INDEPENDENCE DAY. Celebrate your independence of the sewer grid, and remember that with this independence comes the responsibility of a sewage treatment system operator.I recommend the use of plastic leach field chambers such as the ADS Bio-Diffuser, or Infiltrator brand. Cover each chamber leach field with a 4-foot wide sheet of geotextile fabric (landscaping fabric). The geotextile will prevent the migration of silt into the void under the chambers. The fabric also acts as a wick, wicking by capillary attraction, the effluent up over the chamber units and then into the soil.Install 4-inch monitoring and ventilation ports to the ground surface on each end of each field. The 4-PVC risers are covered with plastic 6-inch round irrigation valve boxes. The tops of the irrigation valve boxes are set at the final grade elevation. The boxes will allow easy location, easy access, and you can run the lawn mower right over them. Typically the covers of the boxes are green.The tops of the in-use field monitoring ports are fitted with 4-inch female threaded adapters, and threaded plugs to prevent sewer gas odors from emanating into the yard. The tops of the resting field ventilation ports are fitted with a 4-inch female adapters, and plastic drain grates.The ventilation ports will allow atmospheric oxygen to enter the leach field, and this will create an aerobic condition in the resting leach field. The oxygen will oxidize the Ferric sulfide (that black slimy crap), a major component of the clogging mat. Also, the aerobic condition will allow the aerobic microbes, present in the surrounding soil, to migrate to the clogging mat and consume the organic matter constituent of the clogging mat, and consume the dead bodies of all their anaerobic microbial cousins. Exchange the solid threaded plugs with the drain grates when the valve is turned on SEWAGE INDEPENDENCE DAY.While you are involved with the major renovation of your septic system, I recommend that 20-inch plastic risers be installed over the inlet manhole, and the outlet manhole of the septic tank. The covers of the risers should be at the final grade elevation to allow easy access to the tank. Let’s face it, if you must excavate the soil over the septic tank manhole with a shovel, chances are that this chore will be avoided. I use Tuf-Tite brand risers.I also recommend that the outlet tee of the tank be fitted with a septic tank effluent filter. The brand that I use is manufactured by SIM/TECH (the big bottlebrush type), although there are several other high quality filters on the market.The filter will reduce the organic matter in the effluent from flowing into the leach field. Clean the filter annually on SEWAGE INDEPENDENCE DAY.Another chore that should be performed annually is the measurement of the sludge accumulation in the primary chamber of the septic tank. The sludge can be measured with a “SLUDGE JUDGE.” Do an Internet search to obtain this neat device. I recommend the implementation of the “1/3 RULE” of sludge removal. When the level of the sludge is 1/3 the total liquid depth of the septic tank, it is time to remove it.The final chore to be performed on SEWAGE INDEPENDENCE DAY is to record all of the maintenance performed on the system in a maintenance log. I prepare a SEWERS CAN BE BEAUTIFUL operation manual for each of the septic systems that I install for my clients. The manual contains a description of the system design, photos of the system components, an as-built plan, a description of the required maintenance procedures, a copy of the permit, and the maintenance log. The manual becomes an excellent sales tool when the time comes to sell the home. The manual answers all questions a potential buyer may have regarding the performance of the septic system, and will allay the fears typically encountered when purchasing a home served by a septic system.Well Dumbdad, I had better end this lengthy diatribe. If all soil absorption type septic systems were designed and constructed to the above standards, then there would be far fewer failed septic systems. Maintenance is the key to successful septic systems. However, if the required maintenance is difficult, or impossible, then chances are it will not be performed.

When to Have Your Septic Tank Checked for Structural Damage

Driving over a septic tank, leach field, or other part of the septic system is something you’ve undoubtedly heard of before. This is largely due to the possibility of causing harm to the system, and partially due to the possibility of the tank collapsing if subjected to an excessive amount of pressure. Extra precautions should also be taken to prevent going across the tank area or standing on the tank lid or other septic tank access points. In addition, if you observe any red signs that might indicate that the tank is in danger of collapsing, you should contact a professional for an assessment and possible repairs immediately.

  1. Inadequate maintenance or advanced age The first item on the list is a tank that has been neglected or is really old.
  2. The less expert treatment your tank has had over the years, the more likely it is that it may develop a structural weakness that will go undiscovered for years.
  3. Tank made of concrete In comparison to fiberglass and plastic tanks, a concrete tank is subject to a certain form of damage that they are not prone to.
  4. A tank that has not been properly erected and vented is more likely to suffer from significant corrosion as a result of the presence of these gases, which can damage the concrete structure over time.
  5. The cover of the tank should not be removed or entered, and you should never stick your head into the tank for safety reasons.
  6. An intake pipe that is not put firmly in the ground but eventually settles can also cause problems since the angle at which the pipe enters the tank varies as a result of the shifting ground.
  7. Additionally, there may be concerns with the tank itself, such as faulty construction, that are at play here.

If someone unintentionally drives over your septic tank with an RV, you may be tempted to hold your breath for a number of days before concluding that everything is alright because the system appears to be functioning normally.

If it has been damaged, it may collapse at a later date.

Consider having your contractor come out for a structural check if you suspect that any of these or other recognized stresses have happened.

Although freezing does not always cause damage to your septic tank, it can do so in the following situations: Extreme cold has been observed to produce cracks in concrete storage tanks in the past.

To ensure that new fractures are not formed in your tank whenever it freezes and you need an expert to come out and thaw it, make sure to have them check for them every time it freezes.

Even if you are unsure of what caused the damage, it is possible that it affected both the below-ground and visible elements of the system.

Maintaining an eye out for these indicators will assist you in identifying scenarios in which your tank may require an inspection for structural issues.

Your monitoring and the attention of your septic contractor, in conjunction with safety measures like as locking riser lids and riser screens, can assist to prevent health and safety problems.

How Water Softeners Effect Septic Systems Part 2

The workings of water softeners were discussed last month, along with the fact that they can have a detrimental influence on your septic system by overloading it. Today, we’re going to talk about another way that septic systems may be negatively impacted, as well as a technique to avoid these difficulties with your septic system in the first place! The Negative Effects of Salt on Your Septic System Surplus water flushed into your septic tank has the potential to overload the system, but saltwater in particular is a big concern to your septic system since it offers two substantial threats.

  1. This causes the saltwater from your softener to fall fast to the bottom of your septic tank, occasionally lifting the sludge and causing it to get suspended in the effluent within your tank.
  2. Solids are allowed to settle to the bottom of a septic tank, allowing clean effluent to flow out to a drain field below.
  3. Salt, on the other hand, is a naturally corrosive element.
  4. This has the potential to dramatically reduce the life of your septic tank.
  5. Because the majority of homes with septic systems also rely on private water wells to give water to the family, we recognize the need of removing minerals from the water supply of the residence.
  6. This may be accomplished through the use of a storm drain or a downspout, both of which will divert softener brine away from your septic system.
  7. If your water softener is currently discharging into your septic system, it is critical that you notify your septic system provider and take steps to reroute the softener brine as soon as possible after learning of the problem.
  8. More than two decades have elapsed since we began working in the sanitation industry.

A septic tank is a sewage collection system that is located underground (Figure 1). A waterproof container composed of a sound, durable material that is resistant to corrosion and deterioration, the tank itself is a watertight container. The most popular form of septic tank is made of concrete. These should be made of high-quality concrete in order to prevent the possibility of early cracking or degradation of the septic tank during the construction process. It is necessary to cover the inside walls of concrete septic tanks with a durable and waterproof compound, such as coal tar epoxy, in order to maintain the tank’s structural integrity.

  • Poly septic tanks are simple to install, despite the fact that they are slightly more expensive to acquire.
  • In recent years, there has been an increase in the number of reports of concrete septic tanks deteriorating prematurely.
  • These corrosive gases have been linked to a number of factors, including the fermentation of food waste from garbage disposals, contemporary cleaning chemicals, particularly those used to remove hard water lime deposits, and the flushing of some pharmaceuticals into the system.
  • It is possible that a polyseptic tank would be desirable in situations where corrosion would be a problem.
  • The number of bedrooms or fixture units (toilets, sinks, showers/tubs, etc.) to be served should be taken into consideration while making your pick.
  • An underground sewage tank being buried in the yard is seen in Figure 1.

How Does a Septic Tank Work?

As the septic system is operated, sediments (also known as sludge) collect in the tank, causing it to overflow. By holding wastewater in the tank for at least 24 hours, the septic tank is able to remove particles by allowing the sediments to settle on the bottom and scum to rise to the surface. Several baffles are installed within the tank to achieve this task. Over time, the solids kept in the tank will degrade to a degree that might reach 50%.

The treated effluent water is discharged from the tank through perforated drainpipes into the environment. The pipes are buried in an absorption or “leach” field that has been created. Water seeps out of underground drainpipes and percolates into the earth, eventually reaching groundwater levels.

Septic Tank Maintenance

Sludge will collect in your septic tank as a result of the use of your system. Tanks that have been properly built may store enough material for up to three years of safe buildup. At this point, the separation of solids and scum has ceased to occur, and sewage may overflow into the absorption area as a result of the accumulation of sludge. Pumping the collected sludge on a regular basis might help to avoid this problem.

How Often Should You Pump?

Pumping frequency is determined by the following factors:

  • Septic tank capacity
  • Volume of wastewater flowing through it
  • The amount of solids present in wastewater

The volume of wastewater produced by ordinary home activities such as flushing toilets, bathing, and washing dishes is governed by the nature and frequency of these activities. Water conservation methods in the house will assist in reducing the amount of water that enters the system. The use of an in-sink trash disposal will result in an increase in the amount of solids produced. It is important to consider the type and amount of solids disposed of by a garbage disposal before using one. Continuous running water from a toilet or a leaking faucet, or emptying of a whirlpool tub, can stir up the sediments in a septic tank, increasing the likelihood of sludge leakage into the absorption field and, ultimately, failure of the absorption field.

Please keep in mind that septic tank additives, both biological and chemical, are not required and do not reduce the necessity for regular pumping.

Safe Use of Septic Systems

Motor oil, gasoline, paint, thinner and pesticide should not be flushed down the toilet or down the sink drain. These compounds have the potential to contaminate groundwater and to be poisonous to the microorganisms that keep a septic system operating properly. However, keep in mind that when there is a large density of septic systems, there may be a cumulative influence on groundwater from the use of home cleaners, disinfectants, detergents or bleaches, even when used in moderation. It is possible that the usage of continuous toilet deodorizers, which are placed in the toilet bowl, would kill beneficial bacteria that are necessary for the breakdown of waste in the septic tank.

Your septic system will become clogged by objects such as fats and grease, coffee grounds, paper towels, sanitary napkins, disposable diapers, cigarettes, flushable cat litter, and other items of a similar kind.

Protect the Absorption Field

Motor oil, gasoline, paint, thinner and pesticide should not be flushed down the toilet or down the sink. It is possible that these materials may pollute groundwater and that they will be poisonous to the bacteria that keep a septic system functioning properly. However, keep in mind that when there is a large density of septic systems, there may be a cumulative influence on groundwater from home cleansers. If you use a continuous toilet deodorizer that is positioned within your bowl, you may be killing important bacteria that are necessary for the breakdown of waste in your septic tank.

Your septic system will become clogged by objects such as fats and grease, coffee grounds, paper towels, sanitary napkins, disposable diapers, cigarettes, flushable cat litter, and other similar products.

Conserve Water

When adding new appliances or plumbing, keep in mind that the capacity of your septic system must be taken into consideration. Reduce the amount of water that enters the tank. Make use of water-conserving fixtures. Toilet float valves, leaks, and leaky faucets should all be repaired.

Avoid Septic Tank Additives

Yeasts, bacteria, enzymes, and chemicals are offered with the idea that they will improve the performance of septic systems; however, there is no scientific proof that these additions are helpful. Some cleaners, in fact, enable the sediments in an overcrowded tank to be re-suspended, causing the drainage lines to get clogged. Supplements are not a substitute for adequate maintenance and do not negate the necessity for regular pumping of a septic tank. Commercial biological additives are not required for resuming decomposition after pumping since the sludge residue contains active microorganisms that may be used to restart decomposition.

How to Recognize Problems

Become familiar with the symptoms of septic system disorders. For example, extremely lush and green grass over your drain field may suggest that there is a problem with the drainage system. Pay close attention to any slow-draining toilets or drains, sewage aromas, or sewage backing up into the home or over the drain field, among other things. Septic Tank Maintenance Checklist for Effective Performance

  • Discover how to identify issues with septic systems. Having particularly lush and green grass over your drain field, for example, may suggest that there is an issue.

Tank System Reconstruction Replacement of the baffle A baffle is a barrier or shield that is installed in front of the tank’s inlet and exit openings. These shields, which are made of concrete, PVC, or plastic, are critical to the effective working of the system. The entrance baffle, which is partly submerged and half exposed to the water, is meant to redirect incoming waste down into the tank, preventing the tank from being agitated. When you agitate the tank, the settled sewage rises to the surface, flows out of the tank, and plugs the drainfield.

  • One of the most common reasons for septic tank lines to become clogged is the absence of a baffle within the tank.
  • At each service visit to your septic system, we perform a visual inspection of each baffle to ensure that they are in good working order and performing their function!
  • Tank Ventilation and Sealing In the course of time, tanks, particularly those built of steel, can degrade and develop holes through which ground water can enter the tank.
  • Excavation for coverDigging We will find your tank cover and dig up your tank for you at no additional charge.
  • During the winter months, we may thaw the ground with the help of a heat blanket, which will make digging more convenient.
  • Some tanks have deteriorated to the point that the structural integrity has been compromised, and in those cases, we urge that they be replaced.
  • During this repair operation, a tank entrance will be created in order to install a custom-made polypropylene piece that will protect the wall and serve as a baffle.

This is only a short-term solution. A rusted tank will eventually need to be replaced, but this repair can significantly extend the life of the tank.

3 Tips to Maintain Your Concrete Septic Tank – Septic Maxx

Septic tanks are available in a variety of shapes and sizes and are constructed of a variety of materials, including cement, steel, and plastic, each of which has its own set of pros and disadvantages. Tanks made of concrete:

  • Possess high effluent concentrations
  • Possess a low likelihood of rising to the surface Are authorized in every state (as opposed to plastic tanks), and are environmentally friendly.

The fact that a majority of Americans choose concrete septic tanks over tanks made of any other material is a testament to these advantages. However, despite all of these advantages, if you have a concrete tank, you should be aware that it is possible for your tank to break under harsh weather conditions. This might result in costly leaks, which would make maintaining a concrete septic tank very difficult. These straightforward suggestions may assist you in maintaining your concrete septic tank and preventing cracks.

Reuse of Concrete Tanks

A long time has passed since concrete septic tanks were employed because of their durability. Despite the fact that they are prone to cracking, many people choose to reuse existing tanks in order to decrease maintenance and installation expenses. Before reusing a concrete tank, it must first be properly evaluated to verify that it is structurally sound and free of defects. Following the examination, the concrete tank must be refitted with a liner that is attached to the interior of the vessel.

It can also help to prevent corrosion, which is a leading cause of septic system failures, which can be quite expensive.

Repair Minor Damages

You should take care of any little damage to your concrete tank as soon as possible. As a result, you may extend the life of your septic tank and avoid minor problems from becoming major problems. The following are examples of typical concrete septic tank damages:

  • Pipe inlets and outlets that have been worn out
  • Baffles that have been damaged

Regular Inspections

The maintenance of a healthy septic system is essential. Pumping and inspecting your septic tank on a regular basis are required to keep it in good condition. Pumping is the process of removing sludge from a tank, whereas inspections are the process of checking the overall operation of the system. Identifying problems early on can save you from having to pay for incredibly expensive repairs later on. The proper maintenance of your septic system might assist to extend the life of your septic tank.

Septic Maxx provides environmentally friendly septic tank solutions that may do this, as well as minimize unpleasant odors and prevent material build-up in the tank.
