Age of the System It’s pretty common for a septic system to last 40 years or longer, which means if you buy a new home, you might never need to replace it. However, you might have an older home whose septic system has been in place for nearly half a century.
- How Long Does A Septic Tank Last The short answer is that a septic system can last anywhere from 15 to 40 years. The reason that it’s such a wide range is because there are many different factors that determine the life expectancy of a septic tank.
What are the signs of a failing septic system?
8 Signs of Septic System Failure
- Septic System Backup.
- Slow Drains.
- Gurgling Sounds.
- Pool of Water or Dampness Near Drainfield.

How often should a septic tank be replaced?
Typical lifespan is in excess of 30 years for GRP, PE and concrete tanks. Assuming optimal conditions of install and use, you could expect the following: Steel septic tanks have a life expectancy of 15 to 20 years.
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.
Do septic tanks ever need to be replaced?
Unfortunately, septic systems don’t last forever. With regular maintenance and pumping, your septic system can last many years. However, after decades of wear and tear, the system will need to be replaced.
Can I shower if my septic tank is full?
Only the water would get out into the leach field in a proper system unless you run too much water too fast. The thing to do is to run your shower water outside into it’s own drain area, but it may not be allowed where you are. Used to be called gray water system.
How do you tell if your septic tank is full?
How to tell your septic tank is full and needs emptying
- Pooling water.
- Slow drains.
- An overly healthy lawn.
- Sewer backup.
- Gurgling Pipes.
- Trouble Flushing.
Can you sell a house with an old septic tank?
If you’re selling a property with a septic tank, then you must be transparent with buyers about the fact the property uses a one and provide a detailed specification of the system. In fact, You are required by law to inform a buyer in writing about the presence of a septic tank.
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.
Are septic tanks still legal?
Septic Tanks Explained… Septic tanks cannot discharge to surface water drains, rivers, canals, ditches, streams or any other type of waterway. you are required to upgrade or replace your septic tank treatment system to a full sewage treatment plant by 2020, or when you sell a property, if it’s prior to this date.
How much does it cost to pump a septic tank?

Is Ridex good for your septic system?
How additives, like Rid-x, interfere with your septic system’s eco-system. According to the EPA and the Ohio Department of Health, not only are additives like Rid-X not recommended, but they actually have a detrimental and potentially hazardous effect on your septic system’s waste treatment process.
How long should a drain field last?
It’s important to consider the life expectancy of a drain-field, too. Under normal conditions and good care, a leach-field will last for 50 years or more. Concrete septic tanks are sturdy and reliable but not indestructible.
How many loads of laundry a day are safe to do with a septic tank?
Spread Out Laundry Loads These use less water which puts less stress on your septic system. Regardless of the type of appliance you have, you should still spread out your loads. Instead of doing several loads in one day, consider doing 1 load per day or space out 2 loads if you must do more in a single day.
How long does a septic system last?
What is the average lifespan of a septic system? A new septic system will typically last between 20 and 30 years in ordinary use. However, this is not a set in stone figure. The lifespan of a septic system is impacted by a number of different variables. For starters, long-lasting septic systems are those that were constructed appropriately and are kept in good condition. Below is a list of some of the most important elements that influence the lifespan of a septic system: The number of people in the house– it is generally assumed that a typical household uses at least 110 gallons of water per bedroom per day.
Should an excessive amount of water be sent to the septic tank at frequent intervals, the wastewater may be driven out and into the drain field before the bacteria have completed their work of decomposing the organic waste or before the other particles have had time to settle.
Some home items include chemical contaminants that are hazardous to the beneficial bacteria in the septic system, and these products should be avoided.
General, the materials you use in your house will have a direct influence on the overall health and lifespan of your septic system, so choose wisely.
For example, corrosive groundwater can erode a concrete septic tank, causing it to fail.
It is estimated that the typical lifespan of a septic system in Canada is between 20 and 30 years.
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?
The septic tank is in charge of separating the solid organic waste from the liquid wastewater that enters it. Solid particles settle at the bottom of the tank, generating the sludge layer, while grease settles at the top, forming the scum layer. Solid particles settle at the bottom of the tank, forming the sludge layer. As effluent runs from the tank into the drain field, some sediments are washed away with the wastewater, causing the leach field to become clogged over time. Because the leach field is blocked, it cannot accept any more wastewater, resulting in backups, foul odors, and other signs of a failing septic system, among other things.
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.
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
The problem is that the majority of septic system owners inadvertently utilize a large number of dangerous items. Products such as bleach, solvents, detergents, drain cleaners, and antibacterial soaps are created from chemicals that can significantly lower the amount of bacteria and enzymes in a septic tank’s water supply and waste. As a matter of fact, the average septic system contains more than a hundred detectable chemical substances. Solution: Avoid the use of materials that may cause damage to your septic system.
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
In addition to being an annoyance, a malfunctioning septic system poses a threat to public health. In order to prevent this from happening, any problems that arise in the septic system should be addressed immediately. A biological issue or a mechanical failure are the most common reasons for septic systems failing.
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.
Keep in mind that accessing a septic tank is extremely dangerous, so do not attempt to fix it on your own. 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
There is always an exception to the rule when it comes to mechanical difficulties. Biological solutions should be tried first when a septic system fails, according to experts. The biological approach will work more often than not, and you will save thousands of dollars as a result of this. Despite this, mechanical issues do occur from time-to-time. The faulty design of the tank, the driving of automobiles and other heavy machinery above the septic tank, as well as corrosion from gases such as hydrogen sulfide, which are produced by the anaerobic bacteria’s activities, are all examples of factors that can cause tank cracking.
- Cracks in concrete septic tanks can be repaired using one of two ways.
- Concrete filler is poured to the crack in the lid and should take care of the problem.
- Although it is possible that a fractured lid indicates that the concrete tank has been damaged as well, it is best to have an expert evaluate it to ensure that everything is in working order.
- Cracks that are too tiny to see can be ignored.
- The only cracks you should be concerned about are those that are excessively large or those that are already causing wastewater to flow out.
- Since septic tanks require specialized equipment and safety clothing to be repaired, only qualified and licensed contractors should be used.
- Avoid attempting to fix the tank yourself since accessing a septic tank can be quite risky.
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.
Avoiding utilizing materials that are not septic-friendly is the most effective approach to guarantee that your system is properly cared for. Download this free eBook, which contains a complete list of all the goods that may be causing damage to your septic system.
5 Signs it’s Time to Replace Your Septic System — BL3 Plumbing & Drain Cleaning
Nobody wants sewage backing up into their yard, and there are a number of things you can do to keep your septic system from malfunctioning in the first place. But there are times when it is necessary to throw up the towel on an old system and make the investment in a new one. Because it is a costly option, you will want to be certain that it is absolutely essential. In an ideal world, efficient maintenance would preclude the need for replacement for decades, if not generations. However, years of poor maintenance may lead to the conclusion that a replacement is the best solution.
1. Age of the System
If you buy a new house, it’s possible that your septic system may endure for 40 years or longer, meaning you won’t have to replace it for a lengthy period of time. You may, on the other hand, have an older home with a septic system that has been in place for more than half a century. If you begin to notice difficulties with the system, and if you find yourself pumping it more regularly in order to maintain it operating correctly, it may be time to start planning for a new septic system installation.
2. You’ve Outgrown the System
Septic systems are designed to have a limited carrying capacity. In most cases, the size of a house is determined by the number of rooms and square footage it has. However, if you’ve increased the size of your home or your water usage, you may find that you’ve outgrown the capacity of your septic tank. If your tank is inadequate for your needs, it may be necessary to improve the system in order to better serve your family and your way of life.
3. Slow Drains
Having a septic problem might be indicated by the fact that your sinks or bathtub take an unusually lengthy time to empty. Because this is a tiny sign, it is possible that you are only suffering from a blockage. If, on the other hand, all of your sinks are draining slowly, it is possible that you have a more major problem. Due to sludge accumulation at the bottom of the septic tank, it is possible that the water is going more slowly through the septic tank.
4. Standing Water in the Yard
Any standing water in your yard due to a clogged septic system is a bad omen. However, it is possible that you are only in need of a repair and not a complete replacement. It’s possible that there is a problem with your drain field. It is critical that you do not disregard standing water since the problem will not go away; rather, it will only worsen. It’s possible that your septic tank isn’t the source of your difficulties. Standing water can be caused by a clogged drain field in some cases.
It is desirable to have grass and plants growing over your drain field because organisms aid in the breakdown of the liquid and prevent it from accumulating.
Aeration through mechanical means is the second option.
Your final choice is to seek a replacement. It is possible to repair the drain field without having to replace the septic tank in some situations. You should, however, plan on replacing the tank as well if you find that the majority of the difficulties you are experiencing are connected to age.
5. Nearby Contaminated Water Sources
If nitrate, nitrite, or coliform bacteria are detected in neighboring water sources, this is a strong indication that there is a problem with your septic system. If you notice contamination in water sources, it is critical that you analyze the situation as soon as possible.
Other Septic Systems Issues
The replacement of the septic tank is the most extreme circumstance. A number of these indicators might be symptomatic of simpler problems that only require little correction. If you have obstructions in your septic tank, you may need to have it pumped or have the system cleaned. If you’re concerned about a septic tank problem, the best course of action is to contact a professional for assistance. At BL3, we provide a wide range of sewage line-related services. In order to speak with a plumber, please call (405) 895-6640 in North OKC or (405) 237-1414 in South OKC.
How Long Does a Septic System Last?
What is the average lifespan of a septic system? Homeowners who aren’t familiar with septic systems may be concerned about the expense of replacement. However, depending on the type of septic system used and how well it is managed, a septic system can last for decades. Septic systems are used in rural regions and in communities that are not linked to existing sewer systems to provide sewage disposal. A domestic septic system collects wastewater from the home and stores it in a holding tank. It is possible for particles to sink to the bottom of the tank and fats, grease, and oil to rise to the top because of the tank’s ability to hold effluent.
- How Long Do Steel Septic Tanks Last?
- The type of material chosen to construct the septic tank of the system has an influence on how long it will survive.
- Steel tanks are susceptible to rust, which weakens the structure after approximately 15 years.
- Is it legal to use metal septic tanks?
- While steel septic tanks were previously widespread, they are no longer permitted in many areas of the country.
- For further information on whether metal septic tanks are permitted in your area, consult your local and state legislation as well as construction codes.
- A high-quality concrete septic tank can survive for 40 or more years if it is maintained on a regular basis.
Moreover, the tanks are hefty enough to withstand the buoyant pressures generated by rising water tables.
If the cracks are significant enough, they indicate that the tank should be replaced.
Is it possible to repair a concrete septic tank?
Some concrete septic tank problems can be repaired, but not all of them.
Large fractures and other failures, on the other hand, need the replacement of a concrete tank.
How Long Do Plastic Septic Tanks Last?
They have a lifespan of more than 30 years.
Rising water tables below ground can pose a danger to the stability of lightweight plastic storage tanks.
Septic systems with sand mounds serve residences on their land that have a lot of groundwater or not a lot of soil depth.
The longevity of a sand mound system will be determined in part by the quality of the septic tank that is installed.
However, it is also dependent on how much the drain field has been degraded by home chemical solutions and even antibacterial agents contained in the wastewater.
A Septic Leach Field is expected to last for several years.
The size of the field and the amount of wastewater it feeds can have an influence on its lifespan.
Is it Legal to Drive Through a Leach Field?
It is critical that the leach field be protected at all costs.
The practice has the potential to cause harm to the drain pipes that transport wastewater.
How Long Does a Septic Pump Typically Operate?
The life of a sewage pump is determined by the amount of wastewater it pumps and how frequently the septic tank is filled.
Do Septic Tanks Need to Be Replaced on a Regular Basis?
The material used in the tank determines how long it will last.
Plastic tanks have a life expectancy of up to 30 years.
Puddles or moist soil surrounding a septic tank are indications that it is time to replace the tank.
A rusted steel tank might be an indication that it has to be replaced in order to prevent additional corrosion or collapse.
When it comes to home insurance, are septic tank damage and septic systems covered?
Damage to a septic system is normally covered by homeowners insurance if the damage was caused by one or more of the 16 dangers listed in your policy.
Take a look at the image below. Poor construction, neglect or inadequate maintenance, and abuse allegations, on the other hand, are likely to be denied. The following are examples of assertions that might be rejected:
- Putting off the removal of tree roots
- Chemicals and oils are being flushed
- The septic system is not draining properly. Driving over the tank while on the ground
A septic system is considered a “other structure” and is therefore covered under the terms of a normal house insurance policy. This indicates that your coverage limit is equal to 10% of your total dwelling coverage. As a result, if you have $300,000 in equity in your home, you will have $30,000 available to pay for repairing or replacing your sewage system. You must make a septic system claim under one of the plans mentioned above since house insurance does not cover floods or earthquakes, depending on which event caused the damage.
- Septic systems that have been properly constructed and maintained can be left unattended for an extended amount of time.
- If a system is left idle for a longer period of time, it may produce less wastewater.
- Approximately one out of every three families in Florida is reliant on septic systems.
- The system will survive longer if it is not exposed to domestic food waste, grease, paint, or harsh chemicals, among other things.
- A new sewer pump can be installed to replace an old one, and new drain field pipes can be installed to replace broken ones.
- In addition, there is no way to repair a failed drain field.
- It is possible to complete the installation of a new septic system in a single day or it may take many days.
- Replacement of a leach field might take a day or two as well.
- I hope this has been of assistance!
How Long Will A Septic System Last?
Q:We recently purchased a home that had a septic system that was 20 years old. It’s a simple gravity system with a leach field at its heart. We had the system evaluated before purchasing it, and the inspectors stated that everything “appeared to be in good working order.” The vendors did not keep track of how many times they pumped the tank, although they claimed to have done it “a few times.” How long do you think we’ll be able to get out of this system before it needs maintenance or replacement?
— John et al.
Typical life spans in the business are 20 to 30 years for systems that have been adequately planned and built, have been well-maintained, and have not been overburdened with data.
I just had a conversation about this with a sanitary engineer who has been designing septic systems for more than four decades.
He has also encountered systems that have lasted 40 or more years, although they are the exception rather than the rule. During his presentation, he stressed that it is difficult to forecast the longevity of a single system. There are just too many factors to consider.
Don’t Forget Maintenance
Typically, the leach field is the first component to fail in a septic system system (drain field). The drain field is calculated based on the number of bedrooms in the house, with two persons sharing each bedroom. As a result, a three-bedroom drain field may accommodate up to six people. All else being equal, a drain field that receives little traffic will outlive one that receives a lot of traffic. In the case of a three-bedroom system, if only two people use it, low-flow fixtures and appliances are used, and the system is pumped on a regular basis, it should last for many years.
- Chemicals, grease, and food scraps that are flushed down the toilet will reduce the life of the system.
- The septic tank is the other main component of the system.
- Steel tanks often fail after 20 to 30 years, however high-quality plastic tanks can endure for 30 to 40 years with proper care.
- The lifespan of a system is influenced by a variety of factors.
- Others, like as proper care and upkeep, are completely within the hands of the homeowner.
- Routine pumping, household water conservation, and paying attention to what they flush down the drain — no harsh chemicals, paints, grease, food scraps, or other solids — are the most critical aspects that the homeowner can manage.
- Drainage of yard and roof water away from the drain field is necessary to prevent the soil from becoming saturated.
- Maintain a safe distance between trees and big bushes, as the roots of these plants might block the perforated drain pipes.
Drain field failure occurs gradually in the majority of cases as the soil around the leaching trenches becomes clogged with solids and grease from the septic tank and becomes blocked by the naturally forming “biomat.” In some cases, the drain field may fail completely (due to high-volume water usage and inadequate pumping). Slow drainage, backups on the lower floors of the home, or soggy areas over the leach field with a strong odor of sewage are all signs of a clogged drain. Depending on the size of the tank and the cost of labor and gravel in your area, a new drain field can cost anywhere from $3,000 to $10,000.
A new concrete tank will typically cost between $3,000 and $6,000 to install, depending on the size.
The original drain field will have time to naturally recover after you begin using your replacement drain field, so it should be ready to be used when the replacement drain field is needed.
New Perc Test?
The majority of municipalities will require that you perform a fresh perc test and an in-hole test before they will issue a permit to replace your present leach field or full septic system. If a site has already passed the perc test, it is likely that it will pass again in the future. The opposite is sometimes true because site circumstances (for example, a higher water table) may have altered, or the town’s test processes and requirements may have changed. It’s possible that you’ll need to upgrade to a more expensive form of “alternative” septic system than the one you started with.

How Long Should a Septic System Last? Estimate Your System’s Remaining Time
Previous PostNext PostThe life expectancy of a septic system should be somewhere between 15 and 40 years. The lifespan of the system is determined by a variety of elements, including the building material used, the acidity of the soil, the water table, and the maintenance procedures used, among others. For the purposes of this lifespan prediction, it is assumed that your septic system was properly built and constructed by a trained plumbing professional in accordance with local construction codes.
As we progress through this article, we will examine each of the elements that contribute to the longevity of your septic system and how you may maximize its performance.
Finding out what your septic system is built of is one of the most important aspects to consider when calculating its longevity. There are a variety of materials that may be utilized to create a septic system, but steel and concrete are two of the most commonly seen. Knowing what your septic system is built of is one of the most important elements to consider when determining its longevity. While there are a variety of materials that may be utilized to create a septic system, the steel and concrete are by far the most commonly used ones.
Despite the fact that they are more expensive and often harder to install, there is a solid explanation for this.
The lifespan of a concrete septic tank is often unaffected by environmental conditions such as clogging or rusting of the pipes or the use of inferior concrete in the tank’s construction.
Even a concrete tank, however, should be inspected on a regular basis to check that no fractures have formed as a consequence of ground shifting or settlement, and to guarantee that it is still in excellent operating condition.
When it comes to septic systems, the drain field or leach field is a network of pipelines that branch off from the tank and disseminate the waste contained inside it. You would soon fill up your septic system and have it overflow onto your yard if your drain field was not in correct working order. This might result in a serious health hazard for everyone who comes into touch with any hazardous waste overflow, including humans and pets. In most cases, the pipes that make up your drain field system are constructed of PVC plastic, steel, or cast iron, and they may endure for up to 50 years if installed and maintained properly.
Even PVC pipes should be tested on a regular basis to ensure that they are in perfect working condition.
Identification of a possible issue before it develops into a problem is the most effective kind of preventative maintenance.
An underground septic system’s drain field or leach field refer to a series of pipe branches out from the tank that disseminate the waste contained inside it. It is possible that your septic system will soon overflow onto your yard if you do not have a properly working drain field. This might pose a serious health risk to anybody who comes into touch with the toxic waste overflow. Pipes in your drain field system are commonly composed of PVC plastic, steel, or cast iron, and they have a lifespan of up to 50 years if they are installed and maintained appropriately.
- It is also important to check on PVC pipes occasionally to ensure they are in perfect working condition.
- It is the best type of preventative maintenance to identify possible issues before they become a problem.

In addition, as previously stated, very acidic soil will have a negative impact on the longevity of a septic system. The performance of concrete tanks will be marginally better than that of steel or plastic tanks, but over time, excessively acidic soil will take its toll on virtually any system. When in doubt about the type of soil you have, or when planning to purchase a property that has a septic system, get the soil tested to identify the acidity level in order to avoid costly mistakes. After doing an examination to confirm that the system is in proper operating order, plan routine maintenance to detect any possible difficulties that may occur as a consequence of soil acidity.
A low water table is defined as the uppermost layer of water under the soil’s surface, and it must be low enough to allow wastewater to filter into the soil. It is possible that your property’s water table is too high, which prevents the soil from absorbing water from the drain field. Because there is nowhere else for the water to go, it will back up into your septic tank, eventually overflowing the whole system. If you reside in a floodplain or a low-lying location that is prone to flooding on a regular basis, the soil surrounding your property may have a high water table.
It stands to reason that the greater the amount of use your septic system is subjected to, the sooner it will need to be replaced. There is a significant difference between utilizing a septic system for two people and using it for four persons. However, if a system is adequately maintained, with frequent servicing and periodic inspections, the additional demand and pressure placed on the system by a big family may be reduced significantly. The following is a related topic: how often should a septic tank be emptied?
Routine Maintenance and Inspections
You may have picked up on a recurrent theme when it comes to septic tank lifetime by now. Periodic inspections and expert maintenance of your septic system are two of the most effective strategies to increase the longevity of your system. When purchasing a new or older house, as well as when living in the home for several years, routine maintenance and periodic inspections give the piece of mind that comes with knowing your septic system is in good operating order and is performing as it should.

Septic System Component Life Expectancy
When a homeowner understands the right techniques for septic tank care, such as the frequency of septic tank cleaning and other septic tank maintenance duties, he or she will be better able to extend the life of their onsite septic system and ensure that it is operating effectively.
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
- Septic soakaway beds located in wet soils, near high water tables, near creeks and streams that are susceptible to flooding all have a short life expectancy and may be improperly or illegally installed
- Surface and roof runoff directed into drainfields
- 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. For more information on how water softeners function, see HOW SOFTTENERS WORK. Advice on how to set the water softener timing and salt dose may be found atWATER SOFTENER ADJUSTMENTCONTROLS.
How Quickly Will the Septic System Fail if We Have One or More of the Problems Listed Above?
It is not necessary to pump septic systems (tank and absorption system, or onsite wastewater disposal systems) to ensure that they do not fail instantly. However, an unmaintained septic tank no longer provides enough protection against particles in the soil absorption field. If the drain field is neglected for an extended period of time, it might limit its life and cause system failure, which may need total replacement of the soil absorption field. There are various situations when site constraints prevent the replacement of the absorption field from being possible – or at least impossible using a typical drainfield design method There are a variety of alternative designs available to address these issues.
How long do you anticipate it to endure before costly repairs to the septic tank or to the septic drain field are required?
How Long do Individual Septic System Components like Tanks, Piping, D-Boxes, Filters or Pumps Last?
Without regular pumping, septic systems (tank and absorption system, or onsite wastewater disposal systems) would eventually collapse. Solids are no longer protected from entering the soil absorption field when the septic tank is not properly maintained. If the drain field is neglected for an extended period of time, it might limit its life and cause system failure, which may necessitate a total replacement of the drainage field. There are several situations when site constraints prevent the replacement of the absorption field from being possible – or at least impossible using a normal drainfield design.
So, assuming you’ve addressed these variables in septic system life, how long can you anticipate a septic system to survive before costly repairs to the septic tank or septic drain field are required?
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.
Reader CommentsQ A
Pete Providing your excavator digs enough space around the concrete septic tank and the tank is not damaged, it should be feasible to lift and transport 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 on what you’ve described, a realistic 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?
