  • Can you reuse an old septic tank? In addition to the standard abandonment process of pumping your septic tank and having it rendered useless by filling it with gravel or cement and crushing the tank lids, you have the opportunity to reuse your tank as a cistern. What happens if you don’t empty septic tank?

Can you reuse a concrete septic tank?

Reuse of Concrete Tanks Concrete septic tanks have been used for a long while due to their durability. Although they are prone to crack, many individuals reuse old tanks to reduce repair and installation costs. After inspection, the concrete tank must be retrofitted with a liner applied to the inside.

How do you backfill an old septic tank?

Abandoning Septic Tanks and Soil Treatment Areas

  1. Remove and dispose of the tank at an approved site (normally a landfill).
  2. Crush the tank completely and backfill. The bottom must be broken to ensure it will drain water.
  3. Fill the tank with granular material or some other inert, flowable material such as concrete.

Do septic tanks go bad if not used?

Nothing happens to a septic system if it’s unused. A septic system that sits unused is safe. It isn’t subjected to wear and tear through use. If the tank had prior use, then it may contain solid waste inside of it.

Can you reuse a drain field?

Yes, it is possible, but to do so you have to remove the old field materials and some depth of the contaminated soil below. This is an expense over and beyond what would be the case if there were another place to put a new one.

Can you reuse the water from a septic tank?

The treated water from a home sewage treatment plant is disposed of in absorption trenches or leach field on your property. Wastewater treated to secondary can be reused for sub-surface irrigation whereas water treated to advanced-secondary quality can be used for surface and subsurface irrigation or flushing toilets.

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?

Can you clean a septic tank yourself?

Technically, you can clean a septic tank yourself. However, professionals do not recommend that you do so. If done incorrectly, you can damage your tank, improperly dispose of waste, or fail to remove all of the waste from the tank. You should hire a professional to clean your septic tank for many reasons.

How do I remove sludge from my septic tank?

How to Reduce Sludge in a Septic Tank Without Pumping

  1. Install an aeration system with diffused air in your septic tank.
  2. Break up any compacted sludge.
  3. Add a bio-activator or microbe blend.
  4. Maintain the aeration system.
  5. Add additional Microbes as required.

Should an old septic tank be filled in?

Many people fill in old septic tanks when they switch to a public sewer system for safety reasons. Filling an unused septic tank will prevent it from collapsing, creating a sinkhole in your yard. Have a professional sewer company pump out the tank before filling it.

Can you leave an old septic tank in the ground?

Tanks can be completely removed or they can be destroyed and buried in place. The decision depends on if you plan to use the land for something else, such as a home addition or pool, and need the remains of the tank out of the way.

What are old septic tanks made of?

Septic tanks are made from steel, concrete, fiberglass, or polyethylene. Steel tanks tend to rust, have a shorter service life, and are only found in older systems. Concrete tanks are durable, but occasionally can crack and leak wastewater. Both fiberglass and polyethylene tanks are lightweight and crack-proof.

What if my septic tank has never been 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.

What is the life span of a septic system?

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 do you check an old septic tank?

While the septic tank is open, look for evidence of places where ground water might be leaking into the tank (DO NOT ENTER THE SEPTIC TANK) – and check the condition of the septic tank inlet and outlet baffles to be sure they are in place. If the septic tank is not empty inspect the sewage and effluent levels.

Receive Notifications I spend a significant amount of time working in the Southwest region of the United States. Throughout the region, there has been a continuous drought that has lasted for almost a decade now. Despite the fact that significant El Nio rains and snows have been received, they have not been sufficient to alleviate the water shortages caused by increased demand and drought conditions.

As an illustration, communities encourage the adoption of low-flow or no-water toilets, as well as the recycling of residential graywater flows.

  1. This suggests that, in the case of an abandoned septic tank or system, the septic tank can be converted into part of a rainwater collecting system.
  2. According to a recent study on the subject, having an abandoned septic tank cleaned and disinfected for reuse would cost between $200 and $500 less than properly ditching the tank in the first place.
  3. This is an approach that I feel is beneficial.
  4. However, there are a few things that conservationists and homeowners should be aware of that are not immediately apparent, and I expect that our business will see more questions like this even in places that are set to be served by a wastewater treatment plant.


According to the article’s writers, all of the area’s tank facilities might be utilized in this manner. As septic specialists, we are all aware that this is not always the case, depending on the age and condition of the tanks in question. As a result, the tanks must initially be inspected for structural soundness as the first step. Furthermore, considering the enormous number of cesspools and seepage pits that are employed in portions of the Southwest, we need to assess whether or not they are genuinely tanks that can store water.

  1. Importantly, the tank must be physically sound, meaning there must be no fractures, no damaged concrete, and suitable access points for subsequent cleaning once the first disinfection has been completed.
  2. If there is a septic tank drainfield system in place, the piping into and out of the septic tank must be removed, the connections must be fully eliminated, and the trenches going back to the home must be totally filled.
  3. In a similar vein, any connections to a drainfield or seepage pit must be permanently disconnected and sealed.
  4. For tanks that were previously utilized as pump tanks, it is necessary to remove and properly dispose of all pumps and electrical connections before repurposing the tank.
  5. It is necessary to shut and seal any gaps in the tank that may have been made for electrical cables.
  6. It is recommended that any portion of a system that has come into touch with sewage is considered contaminated material and should be treated accordingly.
  7. It would be necessary to keep a record of custody and secure agreements from sewage treatment facilities or landfills on the side of the receiving facility and the service provider who would be performing the task, among other things.

A mixed municipal solid waste landfill or another certified disposal site should be used to dispose of contaminated pipe, geotextile fabric, rock, or other trench media.


I anticipate that our industry will be confronted with similar problems and challenges in the future. The work will continue to evolve and adapt, therefore we must remain open to new ways and, possibly, other service niches that we can fill in the meanwhile.

Reuse of a septic tank

Our new home will be built on the site of an old bungalow (which will be destroyed) that contains a wastewater treatment system. I believe the drainage field is beyond repair, but we will be installing a new treatment plant nevertheless. Soakaways or rainwater recycling are required for planning purposes, and we have a large enough area to build an SUDS, lagoon, or pond (the name changes depending on what you use it for), which is essentially water with reeds and some sort of natural filter system before it is discharged into the ditch.

  • I have discovered information for doing so from Australia and New Zealand, which shows how to clean the tank before reuse, but I have not been able to locate any material from the United Kingdom.
  • Once the previous septic tank has been decommissioned, it will no longer be utilized for black water.
  • I was planning on treating grey water on a small scale using a holding tank that will pipe the grey water over gravel beds made from any old plastic troughs I can find, but I was wondering if anyone had any experience with this.
  • The new aerated water will break down the few particles that are still there, and you will have a tank full of water that is suitable for watering the lawn.
  • Grey water may be applied directly to the garden.
  • Logged Aunt Gin’s brick and concrete septic tank, which was no longer in service (it was connected to the village’s main sewage system along with all the others), was converted into a rainwater tank.
  • Simply said, don’t top water anything you plan to eat raw for the next ten years unless you’re planning to soak it in a moderate Milton or salt water stirrilant (sp?) for a few minutes beforehand.

Reuse of Septic Question

At least in New York State, the only thing that is done with a current septic system is a perk test, which involves injecting a dye into the system and then pumping a large amount of water through it to ensure that the dye is passing through the leach field. When someone comes to the well, they take a sample of the water and do tests on it. As long as it is good, you will not have any problems. The most significant possible concern that I see with your present septic system is the fact that it is most likely near to ground level due to the presence of a trailer on the land at the time of writing.

If it is solely used for grey water, I would think about not connecting it to your septic system, even though this is against code in many places of the country.

Make sure your drain is installed and that it is properly capped/plugged.

Break out the concrete above the drain and connect it once they arrive.


If you’ve recently purchased an older house, it’s possible that a septic tank is located on the property. This is true even if your home is currently linked to the municipal water and sewer systems. A prior owner may have abandoned the ancient septic system and connected to the city sewage system when it became accessible at some time in the past. Despite the fact that there are standards in place today for properly leaving a septic tank, it was typical practice years ago to just leave the tanks in place and forget about them.

  1. The old tank may either be demolished or filled with water to solve the problem.
  2. It is possible that permits and inspections will be required.
  3. They are dangerous because curious children may pry open the lid and fall into the container.
  4. Falls into a septic tank can be lethal owing to the toxicity of the contents and the fact that concrete can collapse on top of you while falling into a tank.
  5. Eventually, this approach was phased out due to the fact that the steel would corrode and leave the tank susceptible to collapse.
  6. When it comes to ancient septic tanks, they are similar to little caves with a lid that might collapse at any time.
  7. The old tank is crushed and buried, or it is removed from the site.

If it is built of steel, it will very certainly be crushed and buried in its current location.

After that, the tank can be completely filled with sand, gravel, or any other form of rubble and buried.

Tanks can either be entirely dismantled or destroyed and buried in their original location.

The abandonment has been documented and plotted on a map.

It’s possible that you’ll forget about the tank once it’s been abandoned.

As a result, you might wish to sketch a map of the area where the old tank used to stand.

If you can demonstrate that an old septic tank was properly decommissioned, you may be able to increase the value of your property, and the new owners will enjoy knowing that large chunks of concrete are buried underground before they start digging in the yard to put something in it.

It may take some detective work to discover about the history of your land and what may be lying beneath the surface of the earth.

Upon discovering an old septic tank on your property that is no longer in service, contact Total Enviro Services for propertank abandonment procedures that meet with local standards and protect your family, pets, and farm animals from harm or death.

Can You Relocate a Septic System

It is possible that you will need to move your septic system for a variety of reasons. Possibly, you’re thinking about building an addition to your home or you want to beautify your yard and grow trees. Regardless of the cause, transferring your septic system is a time-consuming and complicated procedure. You may move your septic tank system, but it’s important to do it right the first time. Here are some considerations to bear in mind. There are several components to your septic system. Changing the location of your septic tank system entails more than just shifting the tank.

  • Therefore, it is critical to hire a company that is experienced in the relocation of septic tank systems to ensure a smooth transition.
  • Taking the Tank Out of the Ground and Removing It The manhole covers must be removed from the ground before your tank can be retrieved from the ground.
  • Workers will use ordinary shovels to guard the tank after the operation has progressed closer to the tank’s perimeter.
  • Keep this in mind when you plan the move of your storage tank.
  • The tank must be transported at a very modest pace in order to avoid damage to the container.
  • Replacement vs.
  • Older tanks may be difficult to transport and can even come apart during the removal process, so many homeowners choose to replace them rather than attempting to relocate them.
  • Preparing ahead of time will reduce the likelihood of unexpected expenses and complications.

Septic System Frequently Asked Questions

A septic system, sometimes known as a septic tank, is an underground system that processes the sewage that flows from your house before disposing of the treated, cleaner water. Septic systems are typically seen in residential areas. The treated water is subsequently re-introduced into the environment through filtration.

This is critical because untreated sewage may harm nearby streams and water systems, as well as the soil around the perimeter of your septic system. Because your septic system is designed to cleanse and filter sewage, it is critical that it is in proper operating order.

What is a Drainfield?

The drainfield, also known as the leach field, is the area where the water from your septic system is sent after it has been cleansed and filtered. It is necessary to construct a drainfield in order to ensure that water is distributed uniformly back into the soil.

How do I find my septic system?

If you’re fortunate enough to have a contemporary septic system in your yard, it may be equipped with an access lid that is visible from the ground floor. If this is the situation at your residence, locating your septic system is as simple as taking a few steps into your backyard. It’s unfortunate that this isn’t true for older septic systems. It’s possible that you may locate an older system in your home by checking for greener, faster-growing grass or even an area with less growth than the rest of your yard if you live in an older home.

This will show you exactly where your septic system is located in your yard, if you have one.

You’ll need to look for the location where your septic system’s sanitary line exits your home and follow that line until you find your septic tank, which will take some time.

If you are unable to discover your septic system, your yard may need to be dug up by a septic system installation in order to locate your septic tank as a last option.

How long do septic systems last?

Septic systems are not designed to endure for a specific number of years, thus there is no defined time frame. In the event of adequate maintenance, you may expect your septic system to last several decades before it has to be replaced; but, if your system fails or deteriorates as a result of bad care, its lifespan will be drastically diminished. In order to obtain an accurate estimate of how much longer the life of your septic system may be extended, you must first have it checked thoroughly by an experienced septic system installation or repairer.

What’s the advantage of installing a newer septic system rather than an older system?

Although it is not required to install a new system, there are advantages to having a modern septic tank rather than an older one. For starters, when you get a new septic tank, you can be confident that it will serve you for decades if it is properly maintained, and you will not have to worry about it being “too old.” Additionally, newer systems have been modified to reduce the likelihood of your system becoming clogged, and if something does go wrong with a new system or when it comes time to have your septic system pumped, a new system will likely be easier to locate because they are frequently constructed with ground-level lids.

New septic systems also provide a further treatment for your waste water, allowing it to be cleaner before it is released into the surrounding environment.

All of that being said, if your property currently has an older septic system installed, it should not need to be updated as long as it complies with the standards of your local health department and is in excellent operating order.

How much does a new septic system cost?

Installation of new septic systems may be a significant financial commitment, with costs typically reaching tens of thousands of dollars. Whenever you have to replace an outdated septic system, you should look into financing alternatives that will make it simpler for you to pay for a new septic system in the long run. Purchase further information from a septic system installation business on how to obtain septic systems at the most competitive prices while also taking advantage of low-interest financing options.

How big is my septic tank?

Septic tank capacity is determined by the amount of water consumed in your property as well as local codes and requirements. Check with your local health agency to find out how big your tank is before installing it.

Why should my septic system be pumped out?

Without regular pumping, the gases emitted by human waste accumulate in your septic system, increasing the risk of septic tank damage and the need for more frequent pumping. The regular pumping of your septic system will allow you to limit the rate at which your tank deteriorates and save money in the process. It’s crucial to remember, though, that degeneration is unavoidable in the long run. It is only via regular maintenance, such as pumping your tank, that your septic system will survive longer.

Does my tank need to be dug up to know if it needs to be pumped?

Risers are commonly found in newer septic systems, which allow you to access your tank from the ground level through a lid. It is straightforward for any septic system professional to determine whether or not your yard has risers placed, and whether or not it is necessary to pump it. If, on the other hand, your tank cannot be accessible from the ground level, it will need to be dug up in order to determine whether it has to be drained. Instead of inspecting your septic system to see whether it needs to be pumped on a regular basis, set a timetable for having your system pumped every 2-3 years.

Why should I have risers and lids installed on my septic system?

As a result, when it comes time to find, pump, or repair your septic system, risers are the best choice since they provide ground-level access to your system. Having a septic system lid will allow you to mow your grass while still being able to find your system with no difficulty. Lids and risers also have the advantage of being accessible all year round, as opposed to earlier septic systems that could only be accessed by digging a trench through your yard. If your septic system has to be pumped or repaired for any reason during the winter months, getting beneath layers of frozen earth can be difficult, if not impossible, and you may be forced to wait until the spring to have access to your tank again.

How often should my septic system be pumped out?

A typical septic system contains a 1,500-gallon tank, which needs to be pumped around every 2-3 years for a household of four, according to industry standards. If you have less than four people living in your house, you will most likely be able to pump your septic system every five years rather than every three.

You should speak with your local health agency to determine the exact size of your tank, and you should consult a septic system business to determine how frequently your tank should be pumped based on the size of your family and the size of your septic tank.

Do I need to have the septic tank pumped if I’m selling my house?

Consult with your local health department to learn about the restrictions that apply to your region of residence. Generally speaking, as long as your septic system has been pumped on a regular basis by a licensed septic system company and recently enough for the new homeowners to be able to live there for a year or two without having to pump the septic system, you should not be required to have it pumped again in the near future.

How do I find someone to pump my septic system?

It is important to be aware that not all septic system businesses are licensed and that not all firms properly dispose of or recycle the waste they pump from your septic system when you are looking for one to pump it. Finding a firm that complies with EPA standards should be your first concern, and then you should look at price, how pricing is split down, and which company is delivering the most honest, economical, and dependable service should be your next consideration. Investigate business evaluations, and when you select a septic system provider to pump your septic tank, be certain that they do the work properly, leaving enough water and waste to keep the sewage decomposing while leaving no visible trace more than a few inches of waste behind.

How much does it cost to have my septic system pumped?

It is recommended that you call many pumpers before making a selection, and that you ask as many questions as possible to ensure that you are receiving the best service for your money. Pumping may cost upwards of $200, so it is always wise to shop around before making a decision. You should not consider it a waste of money to have your septic system pumped when the time comes. By correctly maintaining your septic system, you may avoid spending tens of thousands of dollars to replace your septic system long before it should have been replaced in the first place.

What happens if I don’t have my septic system pumped?

The sediments will pile up in your septic tank if you don’t pump it out regularly, ultimately overflowing into the drain field and clogging the drain field. Backups can occur, causing damage to your property and even necessitating the replacement of your drain field, which can be a very expensive error.

I just had my septic system pumped. Why is it full already?

Septic systems are designed to refill rapidly since the purpose of pumping is not to remove water but rather to remove non-biodegradable waste, and the water itself is not the aim of pumping. Once your septic system has been pumped and you begin to use the water in your house, your tank will quickly refill in order to maintain good operation of the system. If the water level rises to a point where it is above the outlet line, contact your septic system service provider for assistance immediately.

What do you look for when inspecting my septic system?

When we do an inspection, we make certain that your septic system is in good operating condition and that it satisfies the standards for receiving a Certificate of Compliance. If you’re planning to sell your home, you should have your septic system checked out by a professional who is certified by the Minnesota Pollution Control Agency. This will allow you to sell your home faster and for more money, if you can prove that your system has been checked out by an accredited professional. The level of liquid in your septic tank will be checked, and we’ll make sure there is no surface-level discharge.

We’ll also note whether the level of solid waste in your septic tank indicates that it should be pumped, and whether any repairs are required to improve the overall functionality of the system.

The drains in my home aren’t draining as quickly as they normally do. Does this have to do with my septic system?

Backed up drains that empty slowly are not usually big grounds for concern. Check first to be sure that there is nothing obstructing your drain before presuming it’s an issue with your septic system. If only one plumbing fixture in your house is draining slowly, there’s a strong probability that it’s blocked; however, if all of the fixtures in your home drain slowly or leave waste backed up, your septic system likely needs to be inspected and may need to be pumped.

What happens when my septic system fails?

Symptoms of a failing septic system may include minor issues such as drain breaks or pipes that have been stopped, which can be caused by tree roots intersecting with the system. Septic system failure, on the other hand, might indicate that your septic tank has degraded to the point that it cannot be repaired and must be replaced. A blocked drainfield will hopefully not become your problem because it is the most expensive component of your system to replace; nevertheless, if it does, you must act quickly to make the necessary repairs or else your waste will continue to back up, perhaps causing damage to your property.

You’ll need to replace the drainfield as soon as possible to avoid further pollution of drinking water sources.

How do I prevent my septic system from failing? How can I properly maintain my septic system?

Your septic system should degrade at a normal rate over the course of several decades if you maintain it on a regular basis. Maintenance normally consists of getting your septic system pumped on a regular basis and making certain that you do not flush or wash anything down the drain that might block your septic system.

What shouldn’t I flush down the toilet?

As a general rule, only human waste and toilet paper should be flushed. There are several reasons why flushing medicine down the toilet is not a good idea. First, medication might kill some of the bacteria in your septic tank, which is necessary to break down solid waste. Second, drugs can pollute adjacent well water. In addition, you should avoid flushing feminine hygiene items, paper towels, tissues, hair, cat litter (even if it is flushable), diapers, wipes, condoms, cigarettes, and anything else that seems to be inorganic and shouldn’t be flushed down the toilet.

What shouldn’t I pour down the drain?

Grease from the kitchen, motor oil, anti-freeze, gasoline, paint, and food should not be flushed down the toilet or drain. You should avoid flushing anything down your drain other than soap and water, and you should especially avoid flushing any form of chemical down your drain that should not be recycled back into the environment, such as fertilizer.

Is using a garbage disposal bad for my septic system?

Using a trash disposal will result in the requirement to pump your septic system more frequently than you would otherwise need to do if you avoided flushing food particles down your drains.

Too much food collection in your tank might cause your drainfield to clog since the microorganisms in your tank are not capable to digesting it. When using a trash disposal, check with your septic system company to find out how frequently the disposal should be serviced.

Should I add bacteria to my septic system?

Aside from being completely useless, introducing bacteria to your septic tank is also highly discouraged. The bacteria produced by human waste is sufficient to break down the solid sewage in your tank without the need of bacteria supplements or other methods. If, on the other hand, multiple members of your home are using pharmaceuticals, they will enter your septic system through human waste and kill some of the beneficial bacteria in your tank, causing it to malfunction. Please contact the firm who installed your septic system to see whether or not you should be worried about the amount of bacteria-killing compounds entering the system.

There’s a strong sewer odor outside of my house. Could this be my septic tank?

Strong sewage stench coming from your yard might be coming from your septic system, but it could also be coming from someplace else completely. Identifying the source of the smell is important. Check for propane or gas leaks in your home before concluding that your septic system is at fault; however, if your gas or propane lines are not leaking, determine how long it has been since you had your tank pumped, and whether there is any sewage waste in your yard or other signs of septic system failure before making your final decision.

Can my septic system contaminate nearby water?

It is possible for your septic system to pollute surrounding water sources if it is not properly managed or fails completely. In the event that you suspect that your septic system is failing, make sure that it is routinely pumped and inspected by an expert.

My gutters’ downspouts drain into my yard above my septic system. Is this a bad thing?

The drainage of your gutters into your yard above your septic system, and particularly into your drainfield, can be hazardous to your septic system. All water should be diverted away from your septic system in order to minimize flooding and damage to your septic system’s tank or drain field.

How to Fill a Septic Tank

Filling a Septic Tank: A Step-by-Step Guide. Many homeowners have made the decision to abandon their old septic system and connect to the municipal sewage system. It is the responsibility of the property owner to properly dispose of their septic tanks once they have been drained out and are no longer in use. Many jurisdictions allow you to keep the tank in the ground rather than having it removed, however it must be filled in for safety concerns in all cases.

Step 1

For further information, contact your local municipality or health authority to determine whether you need a permit to remove and replace your old septic tank.

Step 2

A water pump can be rented or purchased from your local hardware shop. Tanks that are more than a decade old have most likely accumulated water and debris that must be removed.

Step 3

Remove any standing water in your septic tank by pumping it away. Due to the fact that all garbage should have previously been drained out prior to the commencement of your operation, the water in the tank should only be rainwater or groundwater.

Step 4

Make holes in the bottom and sides of the tank with a drill or other means of puncturing them. This permits any water that will ultimately find its way back into the tank to be drained out safely.

Step 5

Fill the tank with sand or gravel to make it more stable.

Up addition to allowing water to filter through, the sand and gravel also serves to fill in any voids that may occur if the tank were to finally collapse.


Septic tanks should be emptied out by a professional septic system pumper before you attempt to replenish your tank. In order to determine whether or if a certain local septic system provider provides septic tank filling as a service, you may want to phone around to several companies. It’s possible that they’ll have filling instructions on hand as well.

3 Tips to Maintain Your Concrete Septic Tank – Septic Maxx

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

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

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

Reuse of Concrete Tanks

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

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

Repair Minor Damages

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

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

Regular Inspections

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

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

Properly disposing of a septic tank (abandonment)

  • There is no new construction in the abandoned (it is a stand-alone abandonment). The county is in charge of regulating septic systems in your city.

Inspections and required steps

Along with the payment, you must submit an application for an aseptic abandonment permission (PDF). Once you have been issued a permission, you must do the following:

  • Inspect and maintain the tank with the help of a qualified pumper/maintainer Take photographs of the tank after it has been smashed, filled with stones, or removed. Obtain and complete the abandonment reporting form.

Send the following papers to the address below within 90 days of completing the preceding steps:

  • Invoice from a certified pumper/maintainer demonstrating that they pumped the tank before it was abandoned
  • And Photographs of the tank after it has been smashed, filled with stones, or removed from use
  • Form of abandonment reporting (DOC) that has been completed

  • And If the drainfield is located inside the shoreland or wellhead protection area, any permits for a substantial addition or redesign of a dwelling or structure on the property will be required to be obtained. Check with your city to see if there are any shoreland and wellhead protection areas.

Older septic systems

Septic systems installed before January 23, 1996 are considered compliant provided they fulfill the following two requirements:

  1. There is two feet of dirt buffer given, and it is not considered to be a health hazard at this time. This indicates that sewage has surfaced above ground or has backed up into the residence.

This clause does not apply to:

Ask the MPCA: Abandoned septic systems

Inquire about MPCA features by sending an email to Hundreds of Minnesotans have written to us with questions about the issues that the agency is involved with, ranging from trash disposal to water and air quality, to chemicals in products, to recycling and reuse, to contaminated sites, to septic systems. If you have a question for the MPCA’s staff, you may send it using the web form Ask MPCA. Question Is it necessary to do anything with an abandoned septic system before selling a house that has an abandoned septic system?

How would I go about determining whether or not a septic system has been properly sealed?

A map indicating the location of the abandoned system must be included in the disclosure.

It will be the seller’s financial responsibility if they fail to disclose the presence or known state of an abandoned septic system.

Although Minnesota state rules do not mandate a compliance examination prior to the sale or transfer of a property, many county, city, and township ordinances do, particularly in shoreland and coastal communities.

Please keep in mind that a disclosure is not the same as a compliance examination, which is performed by a state-certified specialist to assess whether or not the system conforms with applicable rules.

As Cody Robinson, a soil scientist with the MPCA, says, “it is critical that septic systems are properly abandoned to guarantee that untreated sewage is not discharged into groundwater and to avoid public safety hazards associated with an unmaintained subsurface hollow in the yard.” If you have reason to believe that a system on your property was not properly closed out, or if you need to verify whether a system was properly closed out or not, please contact your local government.

If the property was properly closed out, your local government will get a signed evidence of abandonment. For further information, please see our article on healthy septic systems. More information may be found here. Questions and responses from the MPCA are welcome.
