How can I tell if a septic tank needs to be replaced?
If you observe that your home’s drainage has improved or deteriorated in recent months, this is the easiest approach to determine whether your septic tank requires service.
If you are experiencing septic tank issues and live in an older home, you may have reached the point where you need to replace your tank. In the event that you need to replace your septic tank, here are some warning signs to check for.
- The vegetation surrounding the tank is lush and verdant. This is a warning indicator that your tank is likely broken and will need to be replaced shortly after this occurs. Because a septic system is a closed system, the grass surrounding your tank should not be any greener than it is in any other region of your yard. It is possible that if there is a fracture or leak in the tank, the components in household waste will be comparable to the same compounds present in fertilizer, and that this will encourage the grass to grow more lushly green since the soil conditions are more conducive for green grass. The scent of a septic tank begins to permeate the house. You may be suffering from an unpleasant smell because your septic tank is full or the pump out to the leach field is malfunctioning, and things are beginning to back up in your home. As a result, it is possible that you will hear an alarm sounding from your septic tank. This is an urgent phone call, and you must respond to it as quickly as possible. If this occurs, it indicates that there is something wrong with the tank, and that the level of waste in the tank has risen to a hazardous level.
How do I make my septic tank lasts longer?
In order to make your septic tank last longer, there are various things you can do. Follow these guidelines to keep your home functioning smoothly.
- Avoid throwing food down the garbage disposal, and this includes fats and oils as well as other solids. Consequently, solid pieces may be formed, which may drift through your pipes and obstruct your drain field. Keep chemicals such as bleach and Pine-Sol out of your septic tank since they do not naturally decompose and can cause harm. Other than human waste and toilet paper, do not flush anything down the toilet. You’ll want to avoid using baby wipes or cooking grease since these items will not completely disintegrate in your septic system. Make sure your toilet paper is septic safe by looking at the best septic safe toilet papers. Having your septic tank pumped on a regular basis can help to prevent solid items from drifting down the pipes and cluttering up your leach fields. This will continue to be a recurring maintenance expense, but it will not take up a significant amount of your time. It is not recommended to leave your sewage system unattended for longer than a few months. Despite the fact that it may not be utilized on a daily basis, the more you use your septic system, the better off it is. Planting anything over your leach lines is not recommended. This includes planting trees near your tank or piling up soil around your drain field
- Both of these things can cause harm to your system and poor drainage as a result. Maintain a layer of grass on top of your leach lines. Consider installing a sand or gravelwell away from your leach lines instead, if you do not have enough space for grass.
Why does my septic tank alarm go off?
When there is a problem with your septic tank, your septic tank alarm will sound. Typically, this occurs when the float becomes trapped in the tank and the greywater is not properly discharged to the drain field. Because of this, the level in the tank may rise, allowing the water to flow back into the tank and into the home. Normally, this is the point at which the alarm is activated. If it keeps going off, it’s possible that there’s a leak in the system that has to be repaired by an expert.
What to do if your septic system needs to be replaced?
The first step is to call a septic specialist to do a clean-out on your system. Following your initial consultation with an expert, be sure to inquire about the typical life expectancy of your tank as well as any indicators that indicate it may be time to consider replacing your tank. Most tanks have a lifespan of 20-30 years; if your tank is older than that, you’ll most likely need to replace it before you’ve tried all of the various maintenance methods. Nonetheless, it’s crucial to be aware that some variables might shorten the life expectancy of a water storage tank.
Septic Tank Lifespan FAQ
Under normal conditions, a septic tank will last around 20-30 years; however, if the septic system is on the small side and/or needs to be serviced 50 or more times over its lifetime, it is advised that the tank be replaced. If you keep your septic tank in good condition and do regular maintenance (such as septic tank pumping), it will last even longer.
How much do septic tanks cost to replace?
A new septic tank can cost anywhere from $3,000 to $10,000, depending on the size, location of the tank, kind of system utilized, and whether or not a leach field needs to be erected in addition to the tank.

Pumping a septic tank should be done every 1-3 years, depending on how often it is used, to prevent it from filling up and causing damage.
Do septic tanks ever need to be replaced?
They do, in fact. Most tanks have a lifespan of 20-30 years, so if your tank hasn’t been updated yet, it’s likely that it’s time to upgrade your septic system as well.
Can septic system fumes be harmful?
Yes, the vapors emitted by septic systems can be hazardous. Because of the presence of septic gases, a wide range of ailments, including respiratory infections and headaches, can occur if the tank is not working correctly. If your septic system does not have adequate ventilation or is located in a particularly moist environment, it is probable that you may suffer from one or more of these diseases from time to time.
Can septic tanks be repaired?
They have the ability to do so. Septic tanks have a service life of 20-30 years, with the majority of that time being dependent on how well they have been maintained. Every 2-3 years, cleaning out your septic tank will assist to extend the life of your system and prevent clogs from forming in your drain field.
Some elements, like as the lid, can be simply replaced, while other pieces may require total replacement, in which case it may be advisable to replace the entire tank at that time.
Can septic tanks freeze?
They are capable of doing so. Septic tanks have a service life of 20-30 years, and the majority of that time is dependent on how well they have been maintained throughout that time period. Cleanouts of your septic tank every two to three years can assist to extend the life of the tank and prevent clogs from forming in your drain field. However, although certain sections, like as the lid, are relatively simple to repair, other components may require total replacement, making it necessary to replace the entire tank at that point.
What can shorten the septic system life expectancy?
The performance of a septic tank is mostly dependent on the pump and the amount of household consumption. That example, given comparable conditions, a 1,000-gallon tank would most likely endure more than 20 years (on average), but a 500-gallon tank might only last 10-15 years. Aspects such as the size of your home are also important: The likelihood of needing a septic tank replacement increases if you have four or five people living in your house as opposed to two or three individuals living there.
Can concrete septic tanks last forever?
No, however they do have an extended shelf life compared to other options. Concrete septic tanks normally last 20-40 years, however plastic tanks only last 30-40 years on average.
What is the average life of a steel septic tank?
In terms of septic system installation, steel septic tanks are not a good choice because they only last 20 years, but concrete and plastic septic tanks may last 30 to 40 years on average.
Do concrete septic tanks go bad?
It is common for steel tanks to survive between 10 and 20 years, but a well-constructed concrete tank will last much longer. If your tank hasn’t been changed yet, it is likely that it is also time to repair the drain field.
How often should you replace a conventional septic drain field?
It is common for steel tanks to survive between 10 and 20 years, but a properly-constructed concrete tank will last much longer. If your tank hasn’t been changed yet, it’s definitely time to rebuild the drain field as well.
What causes septic drain field failure?
The following are some of the most common causes of septic leach field failure: old age, faulty installation, high usage, and an increase in waste load.
Is it time to get your septic tank checked?

Concrete Septic Tanks Are Probably The Best Option — Build With a Bang
Concrete Septic Tank with a Capacity of 1000 Gallon When it comes to septic systems, whether you’re in the market for a new system or just need a replacement tank, you’ve arrived to the perfect location. As part of our recent investigation into different types of septic systems that are available for your house, we decided that it would be a good idea to also investigate the many types of septic tanks now available on the market. The following are the three most common types of septic tanks that are easily accessible for installation: When constructed properly and maintained on a regular basis, the majority of concrete septic tanks may endure for up to 40 years.
- Waste flow, home size, square footage, number of bedrooms, number of bathrooms, and a few other factors are taken into consideration in septic tank size recommendations and charts.
- Septic tanks are available in a variety of sizes, and you can even obtain tanks that are smaller than 1000 gallons; however, we recommend that you go with a tank that is at least 1000 square feet in size.
- Consult with a licensed expert before purchasing or installing any equipment if you’re going to install a new septic tank or septic system for the first time.
- ” A few of states are now requiring 1000 gallon tanks as the minimum size requirement.
- The popularity of the concrete septic tank can be attributed to its strength, weight, and longevity.
Check out these 6 septic systems available for your home.
Nowadays, most concrete septic tanks are sold with a two compartment design, as opposed to the earlier style one compartment tank that was more common previously. Two compartment tanks tend to perform a better job of filtering and separating waste than one compartment tanks, which is why septic experts advocate them over a single compartment tank. All compartments are constructed with access for cleaning and pumping, regardless of the number of compartments in the system. Because it can readily handle most 0-3 bedroom dwellings, a 1000 gallon septic tank is the standard size for domestic applications.
Heavy Duty Options
Many tanks are also available in “high duty” configurations, which generally have a reinforced top and bottom.
Purchasing the heavy-duty version may be a wise decision in the case that a vehicle, agricultural equipment, or other large piece of heavy machinery passes over the tank area.
Because of their size and weight, all concrete septic tanks must be professionally installed.These tanks are constructed of the heaviest materials available, and although they are durable, they require large, heavy equipment to install.If your concrete septic tank’s proposed or current location does not allow for heavy machinery, you may want to consider a fiberglass or plastic (polyethylene) tank.Because most concrete tanks are precast, they all differ in size, weight, and aeration requirements.If your concrete s However, keep in mind that all of these specs are approximations and are subject to change depending on state and local regulations.

1000 Gallon Concrete Septic Tank
Septic tanks of 1000 gallon capacity or larger are the most typical size for household usage, as they can readily fit most 0-3 bedroom dwellings. Size Weight: The weight of each concrete tank is different. Some of the most common 1000 gallon concrete precast tanks are around 5′ 1″ X 8′ 2″ X 5′ 8″ in size and weigh almost 9,000 lbs. Others are approximately 5′ 1″ X 8′ 2″ X 5′ 8″ in size and weigh almost 9,000 lbs. Here are some examples of Jensen Precast projects completed in various cities around the United States.
1250 Gallon Concrete Septic Tank
Generally speaking, a 1250 gallon tank is a good choice for mid-size homes with 3-4 bedrooms. Size and weight: The sizes and weights of all concrete tanks are different. 1250 gallon concrete precast tanks are typically 5′ 9″ x 8′ 6″ x 5’8″ in size, with some of the more common models being 5′ 9″ x 8′ 6″ and others measuring 5′ 8″. The typical weight of a 1250 gallon concrete tank is 11,000 lbs, however this might vary depending on the distributor. Approximately 11 1/2 feet in depth, however this varies according on the distributor, state, and local statutes.
1500 Gallon Concrete Septic Tank
Generally speaking, a 1500-gallon tank is the most popular size for large homes with five or more bedrooms. Size and weight: The sizes and weights of all concrete tanks are different. The dimensions of some of the most common 1500 gallon concrete precast tanks are around 6′ x 10′ 9″ x 5′ 5″ in length and width. The typical weight of a 1500 gallon concrete tank is 12,000 lbs, which is rather heavy.
Approximately 12 feet in depth, however this varies according on the distributor, state, and local statutes. Baffles at the input and output of the system aid in the separation of solid waste items, oils, and scum from the effluent.
When installing a septic tank, an inlet baffle should be put on the inlet part closest to the point at which the sewer tank joins from the house structure to the tank. Due to the fact that it prevents scum and oils from blocking the entrance pipe, the inlet baffle is critical to the overall health and effectiveness of the septic system. The intake baffle is a bottle neck that is especially designed to do the following:
- In order to prevent the breakdown process from being disrupted, it is necessary to slow the effluent entering the septic tank. A fast rate of inflow of effluent might cause problems by mistakenly combining the settled solid waste with oils, scum, and effluent. Make sure no sewage gases are allowed to enter the sewer line. These gases have the potential to infiltrate back into a home or structure, generating a foul odor.
Every septic tank should be equipped with an exit baffle that is connected to the discharge line. The outlet baffle functions as a bottle neck in the same way as the inlet baffle, but in the opposite direction. It is meant to:
- Preserving the septic tank by keeping scum, oils, and solid waste contained inside
- It is necessary to prevent the discharge of waste items other than wastewater into the output pipe, drain field, and leach field.
All effluent from the septic tank must be clear of solid waste before it may be discharged. Other than that, the solids and oils will pollute the drain field/leach field and result in backups and pollutants entering the surrounding environment. Ensure that your baffles are correctly built and that they are not in need of repair by consulting with a licensed septic technician before doing anything else. Septic tanks made of fiberglass or polyethylene (polyethelyene) are also a suitable option, especially if your location has specialized environmental requirements.
In contrast to concrete septic tanks, which normally need a vehicle equipped with a crane and boom, fiberglass and polyethylene septic tanks are quite simple to transport. Therefore, fiberglass and plastic tanks are frequently employed in places where concrete septic tank delivery vehicles are unable to reach the tanks. The majority of fiberglass and plastic septic tanks weigh roughly 300 pounds or more, however concrete septic tanks can weigh up to 20-30 times as much.
If you’re seeking for a less expensive alternative to concrete, fiberglass and polyethylene (polyethylene) are excellent choices. The majority of fiberglass and plastic septic tanks are thousands of dollars less expensive than concrete septic systems.
When compared to a concrete septic tank, both plastic and fiberglass septic tanks have a lower likelihood of breaking. Furthermore, because fiberglass and plastic are nonporous materials, there is typically no problem with tree or bush roots growing into the tank and generating leaks as a result of root damage. Having said that, due to the tank’s smaller profile and lighter material composition, caution must be used during installation because heavy gear might easily harm it. Tanks made of fiberglass or plastic can be destroyed in the same way as concrete tanks can if too much weight is placed on the surface above them.
Despite the fact that plastic and fiberglass tanks are quite resilient, they can nonetheless leak under specific circumstances.
As a result, it’s important to contact with a septic installation specialist before making a final decision on a certain material. The size of the lot, the position of the tank, the amount of ground water, and the weather can all influence the selection.
Plastic and fiberglass have a number of advantages, but they can also be troublesome. Yes, the lightweight character of these materials makes them perfect for installation, but same lightweight nature also results in a high level of buoyancy in the final product. It is possible that during a storm, a plastic or fiberglass tank can get dislodged from its couplings, causing considerable damage to the septic system and the homeowner’s property, with repair costs in the hundreds of dollars. A simple solution is to place a concrete slab on top of the tank to help weigh it down.
If you reside in an area with a high groundwater table, consult with a specialist to ensure that the higher water table will not cause harm to your fiberglass or plastic tank.

How Quickly Does A Septic System Fail? How long will a septic tank, D-box, or absorption bed last?
Keep in mind that the most essential thing a homeowner can do to extend the life of a private (onsite) septic system is to pump the septic tank on a regular basis based on the number of building occupants, the size of the tank, and the amount of wastewater produced. See TANK PUMPING SCHEDULE for further information.
- Septic Tank Pumping Frequency: Assuming you have a working and reasonably-designed septic system to begin with, the most major action you can take to extend the life of your septic system is to have the septic tank cleaned or “pumped” on a regular basis. See TANK PUMPING SCHEDULE for further information. the name of a table that calculates how frequently a certain septic tank need this treatment
- It is important to understand how the septic system is used, including the amount of wastewater produced and the kind of things that are flushed down the septic system drains. Reducing the amount of water used lessens the stress on the absorption field. By avoiding the use of chemicals or materials that do not biodegrade, the pace of solid build-up in the septic tank can be reduced. Please see the section “DON’T FLUSH INTO THE TOILETthese items into a septic system” for a list of what is and is not acceptable to flush down toilets or down building drains
- Soil conditions such as soil percolation rate, ground water or surface water levels, and the volume and level of ground water or surface water that have an impact on the soil absorption area or drain field The materials used in septic tanks corrode over time, first losing their baffles (which causes drain field obstruction) and then rusting at the bottom or sides of the tank. The pace at which rust develops is determined by the soil conditions, soil acidity, and other variables. When properly installed and maintained, an unlined concrete septic tank may last for over 40 years, excluding instances of improperly mixed concrete or acidic soils, both of which might shorten the tank’s life expectancy. Unless they are mechanically damaged, plastic or fiberglass septic tanks may be expected to survive for a similar amount of time. In many cases, the lifespan of Special Components (such as effluent pumps or septic grinder pumps) along with the lifespan of septic filters, media, and sand bed filter systems dictates the requirement for maintenance of alternate-design septic systems that make use of these components. Trees or plants in the vicinity whose roots have infiltrated system components

- And roof or surface runoff directed into drainfields The following is the water use in the building: The amount of water used in a building has an impact on the drainfield, as do exceptional or abnormal amounts of water consumption, such as toilets that are always running. See When a toilet runs continuously or a water softener is stuck in the “backwash” cycle, it can overwhelm a septic drainfield, causing it to break and contaminating the surrounding area. Similarly, a water softener that is trapped in the regeneration cycle and continues to run can cause flooding in septic fields, and a water conditioner that is incorrectly calibrated can introduce an excessive amount of salt into the water can cause damage to the drainfield.

How Long do Individual Septic System Components like Tanks, Piping, D-Boxes, Filters or Pumps Last?
A steel septic tank will rust out on a timeline that is determined by the acidity of the soil, the grade of the tank steel, and the integrity of the coating. An older steel septic tank, such as one that is 15 or 20 years old, is likely to have corroded to the point of losing its baffles and maybe having a rusted out bottom, which are issues that can be identified during septic tank cleaning and inspection. A steel septic tank cover will survive until it is either driven over by an idiot or rusted away.
- A traditional septic drain field has a variable life span that is determined by the soil percolation rate, the drainfield size, and the degree of usage.
- I’ve witnessed a traditional septic drainfield collapse within 24 hours of being used for the first time on a new system due to improper pipe installation.
- If you ask your neighbors who have comparable soils and systems, they may be able to provide valuable insight.
- A septic tank is simply one component of a complete on-site wastewater treatment system.
- Preserving the septic tank, on the other hand, will help to extend the life of the absorption system, leach field, or drainfield, which is the more expensive second part of the onsite wastewater treatment system.
What to Do ifyou have just moved into a home with a septic system
If you’ve recently purchased a property that has a septic tank, you may not be aware of the size of the tank, its maintenance history, or even the location of the septic tank in question. As a result, you should have your tank emptied out and checked for damage. The business that is pumping the tank will be able to tell you the size, age, and condition of the tank.

Pete Providing your excavator digs enough clearance around the concrete septic tank and the tank is not damaged, it should be possible to lift and relocate the tank without difficulty. I need to relocate a 1000-gallon septic tank because of construction. My main concern is the tank’s structural stability given its age. It’s 40 years old and appears to be in fine shape; the baffles have exhibited just little degradation. Without pumping, I can’t see the edges or the bottom of the tank. If the baffles appear to be in excellent condition, I suppose that would imply a tank that is sufficiently sound to transport.
Additionally, the baffles and concrete of the distribution box appear to be of high quality (I do realize this is a separate entity).
Please keep all comments to a minimum.
“Code” compliance is, of course, a contentious issue; no one purchasing a 40-year-old home can reasonably expect that all of the home’s features will comply with current building codes, nor can the owners be required to update every item to current codes, which cover a wide range of topics from structure to mechanicals to lot line setbacks and clearances to radon mitigation.
- Septic tanks of greater capacity can lengthen the life of any drainfield in general; nevertheless, my 50+ years of expertise in this field leads me to advise that it would be folly to place any expectations on a 40-year-old septic drainfield’s ability to perform.
- It’s all too usual for new homeowners to move into a house, possibly with a younger or larger family, and immediately discover that the drainfield has collapsed due to a lack of maintenance.
- We conducted an examination on a house that was built 40 years ago and still had its original septic system.
- Working with our realtor, I’m attempting to determine if the property owners would be willing to replace it with a new 1500-gallon tank.
- Greg Once the new drainfield has been installed, if there is enough space on the site for it, the contractor leaves everything in the old field in its original condition while excavating new drainfield trenches either in another location or in parallel with the existing trenches.
- If there isn’t enough space, the entire field design is dubious and should be reviewed by a septic engineer who will take into consideration soil perc rates, available space, and other factors.
Beyond that general recommendation, I’m not sure what aspect of your site necessitates the digging up and relocation of existing lines, but I believe it has something to do with a lack of area for the fields.
Just the size of an extra hole that will have to be excavated on my land in order to fit all of the stone, sand, and whatever other materials come with it is something I’m concerned about.
Once again, thank you.
You might be wondering how much excavation and disruption will be required in the first place.
Thank you so much for your prompt answer.
That being said, he said that all of the debris from the failed field would be buried in another location in my yard, which I’m not certain about.
Alternatively, should I request that the material be taken away?
Once again, thank you.
After a few years, you switch between them, giving the one that is “off” time to thin and reduce the likelihood of clogging and failure.
It’s a well-known design, however if I were the builder, I wouldn’t make any guarantees about how long it will last.
See STEPS FOR IMPROVED SEPTIC LIFEHello Sirs and Madams, My standard drain field, which has been in place for 23 years, is nearing the end of its useful life.
His advice is to build a new chamber field and install a valve to allow for switching from one field to another.
He stated that my traditional system will self-restore after approximately 7 years and will continue to function normally.
Thank you for taking the time to read this.
Rita According to what you’ve described, a reasonable planning estimate indicates that you’ll need to:1.
replace your existing septic tank.
create a drainage system (or at the very least scope every drainfield line and dig up a couple of sample cross-sections to see how the field was constructed, amount of gravel, biomat condition) If the tree and its roots are removed, the drainfield must be relocated to an appropriate location.
What about a system that was built in 1978 but has seen minimal use since then?
Twenty years ago, a tree root had broken the cement tank in half, so they chopped the tree root and placed root killer in it.
We wish to bring the property back to life, however we are unsure about the system after so many years of inactivity.
We had a discussion about this system at You’ll see that I’ve presented a number of questions that I hope will assist you get a better understanding of the current state of the system.
We have a steel clargester that has been in service for 30 years and manages the garbage for nine residences.
Ron, how many more years do you think it will be before it has to be replaced?
I wish there was a solution like this that worked and didn’t pollute the environment like some of the harsh chemicals that people have tried in the past.
Is there a method to divide the field into smaller sections?

During the previous year or two, have you found yourself in need of septic repair services more than a few times? Your tank is being pumped more frequently than you recall it being pumped during the same period last year. If either of these statements is correct, it is possible that your system is attempting to communicate with you that it is time to consider purchasing a new tank. Septic tanks are a bit of a mystery to the majority of the population. You’re well aware that there’s one buried beneath your property and that it serves as the nerve center of your complete septic system.
For the time being, at least, until it is necessary to replace or repair it.
Check out some of the aspects that might influence how long your septic installation in Prior Lake, MN can and should last:
- What material is the tank constructed of? This is going to serve as the foundation for evaluating the overall life expectancy of your aquarium. Septic tanks are typically composed of either cement or steel
- Cement tanks may survive for up to 30 years on average, but steel tanks have lifespans of around 15 years on average. The type of material used to construct the tank will also influence the types of difficulties it is likely to encounter in its latter years, including corrosion, crumbling, cracking, and other issues. What is the tank’s carrying capacity? Tanks are available in a variety of sizes and capacities, and the number of gallons your tank is rated for might influence how long it will last you. In a family of five people, a 700-gallon tank is expected to have a shorter lifespan than a similar-sized tank in a five-person household with a 1,000-gallon tank. It all comes down to wear and tear
- What type of maintenance routine do you have in place? The most important factor in determining whether or not your tank will last a long time is how well you maintain and care for it. If you neglect normal maintenance such as pumping and jetting, your tank will suffer as a result of your negligence. On the other hand, adhering to regular maintenance and having the foresight to address concerns before they become worse can result in your tank lasting far into its later years of service. Are there any worries about the property? Even when septic tanks are maintained in the greatest possible condition, environmental critics have been known to cause their premature mortality in the past. Tree roots that grow down into the tank or soil compression that pressures the tank over time can eventually produce problems that are difficult to address without a full septic installation in Prior Lake, MN
- However, a full septic installation is not always necessary.
Maintaining your tank in excellent condition, understanding its capacity, and analyzing its operation over time can assist you in avoiding the need for a complete tank replacement in the future. And while you’ll almost certainly require one at some point in the future, having the peace of mind that you won’t require one right away is a relief to any homeowner.

How long does a septic system drain field last?
A well-built and regularly maintained drainfield should endure for at least 20 years before needing to be replaced or repaired. However, there are a number of elements that influence how long the septic drain field will function well. These are the ones: Because of the way the leachfield was placed, its lifetime will be determined by the specifics of the installation process. Some of the most significant variables to consider are the depth of the water table, the size of the leachfield, and the type of gravel that will be utilized.
Some discharge systems may overburden the drainfield with too much wastewater, resulting in a reduction in the percolation rate of the effluent.
Flooding, surface runoff, and groundwater levels are all critical soil characteristics to monitor during the growing season.
Maintenance– A septic drain field that is maintained on a regular basis will live far longer than one that is not. Pumping the tank every couple of years and adding biological additives on a regular basis are all part of regular maintenance.
Why do septic systems fail?
A well-built and regularly maintained drainfield should survive for at least 20 years before it has to be replaced. Although certain elements influence how long a septic drain field will endure, there are those that are beyond our control. These are the names of the people that are involved: Because of the way the leachfield was placed, its lifespan will be determined by the specifics of the installation process. The depth of the water table, the size of the leachfield, and the type of gravel utilized are all significant considerations.
It is possible that some discharge mechanisms will overburden the drainfield with too much wastewater, reducing the percolation rate of the drainfield.
Seasonal flooding, surface runoff, and groundwater levels are all significant soil variables to consider.
Every couple of years, the tank should be pumped out, and biological additives should be added on a recurring basis.
How to perform a septic inspection
Ultimately, if your system fails and pollutes the environment, the government will order you to entirely replace it. Thus, it is recommended that you verify your system on an ongoing basis to guarantee it is in correct operating order. But, more specifically, how does one go about performing a septic inspection? Starting with the following indicators of a failing system, you may determine whether or not your system is failing:
- Drains that are sluggish to drain
- Septic tank overflowing and flooding the house Yards with standing water and a foul odor
- When it rains and you have drainage issues, you should call a plumber. If you have to pump the tank regularly – more than once a year – you might consider renting a pumping station. If the grass around the septic tank looks to be growing more lushly
Using tracer dye tables to perform a septic inspection
Your septic system is most likely failing if you see any of the following indicators. You should address the problem as soon as possible to avoid it getting out of hand. One other simple method of performing a septic examination is to make use of dye tracer tablets. These are septic-friendly pills that may be flushed down the toilet, and if your septic system is having issues, the dye will emerge on the grass surrounding your drain field.
Common septic tank problems and how to solve them
Hydraulic overload occurs when an excessive amount of water is discharged into the septic tank at the same time. When the tank gets an excessive amount of water, it is compelled to expel wastewater into the drain field before it has a chance to settle. Consequently, excessive hydraulic pressure causes effluent to surface in the yard or to back up into the home. Solution: To avoid this overload, avoid doing too much laundry in a single day and repairing any leaks in the fittings as soon as you find them, says the manufacturer.
Poor or no maintenance
Problem: Failure of septic systems due to lack of regular maintenance is a primary cause of early failure. For example, if you do not clean the outlet filter on a regular basis, it may get blocked, resulting in the failure of the complete septic system. In an effort to limit the amount of time that septic systems are left unattended, the government has made it essential for septic system owners to pump them every two to three years.
Solution: Make a point of pumping your septic tank every couple of years or as often as necessary. We also recommend that you apply biological additives to your septic system on a regular basis to assist keep it healthy and efficient.
Poor design and installation
Problem: Different soil types, bedrocks, groundwater levels, and gradients exist in different parts of the world. It is possible that ignoring such considerations while constructing the septic system would result in the construction of a system that will bring the owner numerous troubles. Solution: In order to get the optimum results, the septic system must be built and constructed specifically for the needs of the property in question. Make sure to talk with a trained engineer and encourage them to do a site inspection in order to provide you with the information you want in order to select the most appropriate septic system design for your needs.
Problem: Driving over, paving over, or building over a septic tank can cause physical damage to some of the most crucial components of the septic tank. Solution: It is possible that the tank or the pipes will move or break, resulting in the malfunction or failure of the system. Solution: Avoid driving, construction, or any other physical activity that might put undue strain on the septic tank and the area surrounding it by not doing so.
Using harmful products
Physical damage to several critical components of a septic tank might come from driving over, paving over, or building over a septic tank. In the event of a tank shift or pipe break, the system will experience malfunction or failure as a consequence. Exclude yourself from any physical activity that might put undue strain on the septic tank, such as driving, building, or any other physical activity.
Flushing non-biodegradable items
Besides human waste, tissue paper is the only other item that can be flushed down the toilet without being harmed by bacteria. Contrary to popular belief, individuals flush anything from condoms to floss to hair to expired medications and face tissue down their toilets. Using these things can cause the tank to fill up more quickly than it should, and some of them can even jam up the pipes. Solution: Other than human waste and tissue paper, do not flush anything else down the toilet.
Because trees and shrubs are quite invasive, they will push themselves into the pipes, which will result in a congested system. Additionally, the roots can rupture pipelines and damage septic tanks, resulting in leaks as a result of their continued growth. Solution: As a general rule, avoid growing trees and plants in close proximity to a sewage treatment facility.
Can you repair a failed septic system?
A clogged septic system is not only a nuisance, but it may also pose a threat to public health. This is why any issue that arises with the septic system should be addressed as soon as possible. A biological issue or a mechanical failure are the most common reasons for septic system failure.
Repairing biological problems
When a system fails due to biological reasons, shock therapy is generally sufficient to restore functionality. The vast majority of septic system owners are unaware that they are using items that significantly lower the number of bacteria in their septic tanks. As a direct result, organic waste is not digested at a rate that is sufficient for it. In order for the septic tank to handle the new wastewater from the home, some of the wastewater already in the tank will have to be discharged into the drain field.
Biological additives bring billions of bacteria and enzymes into your septic system, allowing it to continue to break down organic waste at its optimum level for a longer period of time.
In more than 80 percent of these situations, the septic systems were restored and were able to function at peak performance once again. They were able to save around C$15,000 as a result of this!

Repairing mechanical problems
Mechanical failures are quite rare, but there is always an exception to the rule. Biological solutions should be used first when a septic system fails, as they are more effective than chemicals. More often than not, the biological remedy will be effective, allowing you to save thousands of dollars in the process. It is still possible to have mechanical difficulties despite all of this. For example, a concrete tank may fracture as a result of faulty design, the operation of automobiles and other heavy machinery above the septic tank, and even corrosion caused by gases such as hydrogen sulfide, which are produced as a by-product of anaerobic bacteria activity.
- Cracks in concrete septic tanks can be repaired in two ways: mechanically and chemically.
- Cracks in lids are rather simple to repair — a concrete filler is poured, and the crack should be filled in no time.
- Septic tank cracks need to be corrected in certain cases, however not all cracks in septic tanks need to be repaired.
- Concrete septic tanks are constructed with solid walls, which ensures that even little fractures will not do any damage.
- Initially, the tank will be drained and then allowed to dry before any repairs can be carried out, as is the case in this example.
- When the tank cracks are repaired, the contractor will use cement and crack filler to complete the job.
- Possibly after the tank is completely depleted, it will continue to produce dangerous chemicals that can be harmful to your health and even cause death.
DIY drainfield / septic tank replacement
When faced with a problem with their septic system, some septic system owners choose to tackle the job themselves by building a DIY drainfield. Typically, this comprises emptying the wastewater and then excavating a bed of rocks as a means of fixing a failing drain field after it has been discovered. Performing this or any other type of DIY drainfield repair and replacement is not only risky, but it is also against the law. Septic system inspections are required by law, and if you fail to get them performed on a regular basis, an inspector will ultimately catch up with you, perhaps resulting in a substantial punishment.
However, it is not recommended that you attempt to change the tank yourself because it is quite risky.
If your septic system has deteriorated to the point that it is polluting the environment, it will be necessary not only to replace the tank, but also to completely overhaul the entire septic system, which will cost you more money.
In truth, Canadian environmental legislation does not permit the installation or repair of a septic system by just anybody.
Replacement of the septic system is a major task that may cost you anywhere from $10,000 to $30,000 in labor and materials. It is therefore advisable to ensure that your septic system is operating at peak performance in order to prevent paying such astronomical fees.
How to prolong your septic system life
Your septic system will last for many years if you give it the right attention and upkeep. The majority of septic system owners cause their systems to fail simply by using goods that are harmful to their systems. The average septic tank contains more than 100 identifiable contaminants, the majority of which are derived from home items. The bacteria population in the septic tank is greatly reduced as a result of these contaminants. Due to a reduction in the amount of bacteria in the environment, organic waste will not be broken down properly, which can result in blockages in the drain field, ultimately resulting in the collapse of the entire system.
