The life expectancy of a septic tank can vary according to many different factors, from the environment that it is being kept in, to the material that it is made from. Generally speaking, a septic tank should last for between about 15 and 40 years.
What is the life expectancy of a steel septic tank?
- The average life expectancy of a septic system depends upon its components, and what some of those components are made from. Steel septic tanks can last, on average and with proper maintenance, about fifteen to twenty years. After this time they tend to rust and will need to be replaced.
How long will a septic tank last?
Steel septic tanks have a life expectancy of 15 to 20 years. These should not be used for new installations but can still sometimes be found in older rural properties. Plastic (PE) or fiberglass tanks (GRP) have a life expectancy of 20 to 30 years.
How long does a septic tank last in a house?
If you have a steel septic tank that might be more than 15 years old you should have it inspected as some of the internal components, such as the baffles, may have rusted and will no longer be doing their job.
What are the signs that your septic tank is full?
Here are some of the most common warning signs that you have a full septic tank:
- Your Drains Are Taking Forever.
- Standing Water Over Your Septic Tank.
- Bad Smells Coming From Your Yard.
- You Hear Gurgling Water.
- You Have A Sewage Backup.
- How often should you empty your septic tank?
How often do septic tanks last?
The lifespan of a septic system varies widely — from 15 to 40 years. This is because there are many factors that affect a septic tank’s life expectancy, including its materials and whether it has experienced damage from vehicle traffic, flooding by groundwater or clogging by roots.
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 smell?
A properly-maintained septic tank should be odor-free, so if you notice a bad smell inside your home or outside near the leach field, it’s a sign that there’s a problem. Septic odors are caused by gases in the system, including carbon dioxide, hydrogen sulfide, and methane.
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.
How much does it cost to pump a septic tank?
How much does it cost to pump out a septic tank? The average cost is $300, but can run up to $500, depending on your location. The tank should be pumped out every three to five years.
How can I make my septic tank last longer?
How to Keep Your Septic System Healthy
- How the Septic System Works.
- Don’t Overload the Septic Tank and Drain field.
- Use an Efficient Toilet.
- Don’t Treat the Toilet as a Garbage Disposal.
- Don’t Pour Grease Down the Drain.
- Divert Rain Water From the Septic Drain Field.
- Keep Trees Away from the Septic System.
How do I clean my septic tank naturally?
You can mix about a 1/4 cup of baking soda with 1/2 cup of vinegar and 2 tablespoons lemon to make your own natural cleaning agent. The baking soda will fizz up to help get the dirt and grime in your tub and drains. It’s a great cleaner and your septic system will thank you!
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.
Can a septic tank never be pumped?
What Are the Consequences of Not Pumping Your Tank? If the tank is not pumped, the solids will build up in the tank and the holding capacity of the tank will be diminished. Eventually, the solids will reach the pipe that feeds into the drain field, causing a clog. Waste water backing up into the house.
How do you know if 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. The area of the strongest odor will point to the location of the failure in the septic system.
How do septic tanks look?
Septic tanks are typically rectangular in shape and measure approximately 5 feet by 8 feet. In most cases, septic tank components including the lid, are buried between 4 inches and 4 feet underground. You can use a metal probe to locate its edges and mark the perimeter.
How long can a septic tank go without being pumped?
You can wait up to 10 years to drain your tank provided that you live alone and do not use the septic system often. You may feel like you can pump your septic tank waste less frequently to save money, but it’ll be difficult for you to know if the tank is working properly.
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 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.
If you believe your system is in need of maintenance, we will discuss the best method to go about getting it done as well as possible.
Prior to this, it is recommended that a septic system have a lifespan of between 15 and 40 years. When it comes to how long a system will endure, a variety of elements come into play, such as the building material used, soil acidity, water table, and system maintenance procedures, among other things. In order for this lifespan forecast to be accurate, it is assumed that your septic system was built and installed by a trained plumbing professional in accordance with the building codes in your region.
- This article will go over each of the elements that influence a septic system’s longevity, as well as how to make the most of your system’s life expectancy.
- Steel septic tanks have the lowest lifespan of any type of septic tank, mostly due to the fact that they are susceptible to rust.
- It is essential to get your steel tank inspected on a regular basis to ensure that your good fortune does not run out and that your steel tank does not corrode.
- Do not put off having your steel septic tank tested until it is more than ten years old and has not been inspected within the past six to eight months.
- Rooter, a local plumbing specialist, to have a comprehensive check of your tank and the entire system performed.
- Concrete septic tanks offer the greatest life expectancy of any septic tank material available on the market.
- It is possible for a professionally planned and fitted concrete septic tank to survive for up to 40 years or more.
- 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.
- 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.
- 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. Related Topic: How Do I Maintain the Health of My Septic System?
Acidity of the soil in which your septic system is buried is another factor that can have an impact on the lifespan of your system. If your drain field is buried in hard, clay-like soil, the waste it transports will have a difficult time permeating and dispersing into the soil. This can result in clogs that eventually back up into your septic tank, causing it to overflow and back up into your home. Once again, this has the potential to result in a serious health problem that must be addressed.
- If you have a large family, this is the most effective method of preventing an overflow.
- This is due to the fact that acidic soil has the potential to corrode steel, plastic, and cast-iron pipelines over time.
- Systems that are buried in non-acidic soil have a significantly longer lifespan.
- In addition, as previously stated, very acidic soil will have a negative impact on the longevity of a septic 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.
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.

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.
- 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.
Drive or park over the field, or use it in any way that may crush the earth, is strictly prohibited! Maintain a safe distance between trees and big bushes, as the roots of these plants might block the perforated drain pipes. Grass provides the most effective ground cover.
Drain field failure occurs gradually in the majority of cases when the soil around the leaching trenches becomes clogged with sediments and grease from the septic tank and becomes blocked by the naturally occurring “biomat.” In other circumstances, the drain field may collapse completely (due to high-volume water usage and inadequate pumping). Slow drainage, backups on the lower levels of the home, or moist regions over the leach field with a strong odor of sewage are all indicators of a clogged drain.
If the tank is in good condition and you have a designated area for a replacement drain field, as required in some jurisdictions, the cost of a new drain field will typically range from $3,000 to $10,000.
If you want a fully new system, the cost can easily approach $15,000, and if you require an alternate septic system, the cost can potentially reach double that amount.
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 Often Should A Septic Tank Be Pumped
In the United States, more than one in every five houses – generally in rural regions – relies on an individual onsite system or small community cluster system to treat wastewater, according to the Environmental Protection Agency (EPA).
With the average cost of a new septic system ranging between $3,000 and $7,000, periodic septic system maintenance not only saves homeowners money, but it may also assist to ensure that their homes are safe and healthy.
Septic System Basics
A septic system is comprised of two major components: a septic tank and a drain field. The septic tank is the primary component of the system.
- Tanks are water-tight containers that are placed underground and used to store sediments and scum that have collected from your wastewater
- They are made of concrete, fiberglass, or polyethylene. In a drain field, pollutants are removed from the liquid as it is absorbed into the ground by a layer of soil.
Because it is expensive to replace a septic system, it is critical to keep it in good working order. The more proactive you are in keeping your system in good working order, the longer it will endure. Septic tanks, on the other hand, may survive for up to 30 years or more. The primary objectives of a septic tank maintenance program are to avoid the buildup of sediments in the tank as well as any pollution of groundwater. The good news is that septic system maintenance is not difficult, and can be accomplished with only a few simple tasks.
Septic Tank Cleaning
Drain pipes that link the tank to the drain field will gradually fill with solids and other material and become clogged with debris over time. In order to eradicate and clean any debris that might hinder your system from running smoothly, the majority of pros advocate high-pressure water jetting every five years.
Using Your Septic System Wisely
Following the exit of wastewater from your septic tank, it is directed towards the drain field of your septic system. If the drain field becomes flooded, either from within your system or from outside sources, it might flood, resulting in a backup of the system. As a result of this:
- Planting gardens and trees too close to your drain field should be avoided. Never park, drive, or otherwise operate your vehicle over it. Remove it from the vicinity by diverting roof drains, sump pumps, and other rainfall drainage systems.
The average single-family house uses roughly 70 gallons of water per person, each day, according to the Environmental Protection Agency. According to the Environmental Protection Agency, a leaking or running toilet can waste as much as 200 gallons of water every day. Furthermore, the less water that enters your septic system, the better off you are.
- If you reside in a house with a septic system, you may increase its performance by doing the following: replacing existing toilets with high-efficiency models
- Replacing existing toilets with high-efficiency models Using aerators on faucets, high-efficiency showerheads, and shower flow restrictors to save water. repairing dripping faucets and overflowing toilets Maintaining a safe distance between rainwater drainage systems and your drain field
Another important source of worry is the use of washing machines. The right load size for your washing machine should be chosen carefully. If you are unable to pick the load size, only full loads should be used. Additionally, distribute laundry responsibilities throughout the week. Clothes washers that have earned the ENERGY STAR designation consume 35 percent less energy and use 50 percent less water than regular units. For hot tubs, ensure sure the water has cooled before draining it to avoid any unpleasant surprises later.
Everything that goes down your drains – whether you flush, pour, or grind it (like in a garbage disposal) – ends up in your septic system. There’s no getting around this basic fact: And the health of your septic system is affected as a result. Toilets are a particular source of temptation for far too many of us. According to the Environmental Protection Agency, the only items that should be flushed down the toilet are human waste and toilet paper. There will be no cooking oil, flushable wipes, paper towels, feminine hygiene products, dental floss, diapers, cigarette butts, medications, coffee grounds, paper towels, or cat litter among other items, to mention a few of the most popular.
Also, while dealing with a clogged drain, avoid using chemical drain openers.
Call and ask for our drain cleaning service if a plunger or a drain snake don’t work for you. Even garbage disposals are a source of contention. The majority of authorities advise that people who live in homes with septic tanks should minimize or avoid using them altogether.
Septic System Maintenance
We recommend that you get your septic system inspected by a service specialist once a year to ensure that it is operating effectively. According to the Environmental Protection Agency, septic systems in homes should be flushed every three to five years. When you contact a septic service provider, he or she will inspect your septic tank for leaks as well as the scum and sludge layers that have built up over time. Keep complete records of every maintenance performed, including reports on prospective or present leaks, scum levels, and any potential harm to the system.
- When you get your system serviced, it’s also crucial to have the service provider clean or replace your filter.
- In the service report for your system, the service provider should mention the completion of repairs as well as the condition of the tank.
- Despite the fact that Casteel can handle most common domestic plumbing issues, it does not provide septic tank service.
- Contact the National Onsite Wastewater Recycling Association if you need help locating service specialists in your region (NOWRA).
Septic Tank Treatment
You should utilize living, organic bacteria to break down artificial compounds and sediments that can enter your septic system, such as detergents and soaps. These common home compounds have the potential to harm naturally existing microorganisms that are essential to the correct functioning of your system. Additives that inhibit the growth of bacteria assist to maintain your pipes clean and clear, as well as allowing your system to work correctly and without smells.
Pumping a septic system when it is necessary will help to keep it from failing completely.
How Often Should A Septic Tank Be Pumped?
The result is that septic tanks are normally drained every three to five years for the majority of homeowners. The size of the household, the total volume of wastewater created, the amount of particles present, and the size of the tank are the primary parameters that influence the frequency of pumping. If the top of the scum layer is within 12 inches of your tank’s T-shaped exit, the EPA recommends that you get it pumped. This is because sludge and scum are prevented from leaving the tank. Systems with electrical float switches, pumps, or mechanical components must be examined more frequently, generally once a year, to ensure that they are in proper working order.
Establish a routine to avoid solids from collecting in your system later on.
In certain cases, the presence of bad odors in your septic system indicates that your system is blocked with particles and is therefore more likely to fail. In the event that you fail to properly maintain your septic system and facilities, sewage may back up into your home. If this occurs, avoid coming into touch with the sewage, which may include diseases and bacteria that are dangerous to your health. You’ll want to bring in a professional cleanup crew and report the breakdown of your septic system to your local health agency.
Most importantly, seek the services of specialists. Search the National Onsite Wastewater Recycling Association’s network of service providers to discover a specialist that is knowledgeable and qualified in their field.

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?
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 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?

How Long Will Your Septic Tank Last?
It is still an important system in any home, but because most people pay little or no attention to their septic tanks until they have a big problem, it has become the least well-maintained system in most structures. Fortunately, this is changing. When sewage backs up into a house or foul smells permeate the backyard, most people don’t pay attention to their septic tanks until they experience a problem. Similarly, the majority of people are under the impression that septic tanks are built to endure forever, but the fact is that, on average, septic tanks are known to survive anywhere between 15 and 40 years.
How often do you pump your septic system
The most effective method of keeping your septic tank in good condition is to have it cleaned or pumped on a regular basis. As a general rule, it is recommended that septic tanks be flushed at least once every two or three years. Septic tank service companies that are of high quality will not only pump out your tank, but they will also check it and provide recommendations for any repairs or further maintenance that should be performed on the system.
The type of tank you have
If the acidity of the soil around the septic tank is high enough, steel septic tanks will corrode over time and become unusable. A steel septic tank begins to rust by first losing its baffles (which causes clogging in the drain field) and then rusting at the bottom or sides of the tank. A steel tank that has been in use for 15 to 20 years or more is likely to have corroded. A concrete septic tank, on the other hand, typically has a lifespan of more than 40 years, depending on the conditions.
However, the acidity of the soil surrounding the tank, as well as the quality of the materials used in its construction, have a significant role in its performance. Septic tanks made of plastic or fiberglass have a similarly long lifespan, unless they have been mechanically damaged.
The soil condition under and surrounding the drain-field has a significant impact on the type of tank that may be put in such regions, as well as the lifetime of such tanks. Acidic soils have been shown to have a negative impact on septic tanks, regardless of the materials used in their construction. It is normally recommended that property owners choose reputable organizations that will go as far as assessing the surrounding area and making recommendations on what type of tank to install.
Water usage in the building:
It is important to note that how much water is used in the building will have a significant impact on the longevity of the septic system. A septic drain-field will become saturated if the water use is extraordinary or unexpected. This will result in the drain-field failing.
Septic tanks should not be sited near floodplains or in areas where the water table is high, since this will result in the tank’s lifespan being significantly reduced.
A large number of homeowners who place their septic tanks in close proximity to trees have experienced problems with tree roots infiltrating their septic system. Continued neglect of a septic tank reduces the lifespan of the sewage system and may end in system failure, which may need the replacement of the soil absorption field entirely.
