. Further requirements: The soil dispersal unit/drainfield must never be covered by an impermeable surface that cuts off oxygen.
- Well, when it comes to having either a septic tank or field, you need to have it placed at least five feet away from your home. However, most tanks are placed even farther, commonly around 10 feet away in most cases and the leach fields are placed at around twenty feet away from the home.
How close to septic tank can you build?
– A full foundation must be 10 feet from the septic tank and 20 feet from the leaching area. – A slab foundation such as a garage must be 10 feet from the septic tank and 10 feet from the leaching area.
What is the minimum safe distance from the septic tank?
At least 15m from the nearest water supply. This is a minimum and should be more if the ground is rocky and fissures could take the outflow further. It should be at least 3m from the nearest building. Avoid areas where rainwater would stand or flow over the tank or vehicles could drive over it.
How close can you build next to leach field?
Common guidelines require at least 50′ clearance distance between a well and a septic system tank or 150′ between a well and a septic drainfield or leaching bed but you will see that different authorities may recommend different distances. Local soil and rock conditions can make these “rules of thumb” unreliable.
How close can a well be to a property line in Minnesota?
Property line, unless legally controlled through an easement A community public water-supply well must be a minimum of 50 feet from this contamination source. A well or boring may not be constructed inside a building except as provided for by Minnesota Rules, part 4725.2175.
Can I build a deck over septic tank?
You should never build a deck over a septic field; doing so will prevent the natural draining and dissipation of the effluent. This can ruin the septic system, not to mention releasing foul smells into the air all around your deck. The dissipating effluent can also rot the deck from underneath.
Can you put a garden over a septic field?
Planting over a septic leach field (drain field) is possible if it is done with care. If you have limited space on your property where you can garden, the leach field may be the only spot for landscaping. Vegetable gardening over a leach field is not recommended.
What is the distance between septic tank and well?
The distance between the septic tank and borewell is 15 ft and the dimension of the septic tank is 11X6X7 ft.
How far is distribution box from septic tank?
The D-box is normally not very deep, often between 6″ and two feet to the top of the box. You may also see a pattern of parallel depressions, typically about 5 feet apart, that mark the individual drainfield leach lines. The D-box will at or near end of the drainfield area that is closest to the septic tank.
How far apart do drain field lines need to be?
The individual drain lines will usually be 8½ to 10 feet apart (see Figure 2). It is important to note here that each drain field system will vary from the next.
Can I drill my own well in Minnesota?
In Minnesota, all wells must be installed by contractors licensed by the Minnesota Department of Health (MDH), except that an individual may construct a well for personal use on land owned or leased by that individual, and used by the individual for farming or agricultural purposes or for the individual’s place of
How far should a drain field be from a well?
Septic tank drain fields must be at least 100 feet from a well.
How far does a well need to be from a building?
As a general guidance, personal drinking water wells should have a minimum horizontal distance of at least 10 feet and preferably 25 feet from such boundaries. State or local standards may be less or more stringent in your area.
Isolation Distances From a Water-Supply Well – EH: Minnesota Department of Health
Minnesota Rules, Chapter 4725Rules Relating to Wells and BoringsEffective date: August 4, 2008The isolation distances below are fromMinnesota Rules, chapter 4725. Distances must bemeasured horizontally from the water-supply well.Minnesota Statutes, section103I.205, subdivision 6, prohibits constructing, placing, or installing anactual or potential contaminant sourcefrom a well that is lessthan the minimum distance prescribed by rule. The minimum isolation distance must be maintained between a new well and a contamination source, even if the contamination source is no longer in use. An isolation distance is not required if the contamination source and any related contaminated soil have been removed.Additional information andexplanations can be found in theRules Handbook, A Guide to theRules Relating to Wells and Borings, or bycontacting the Well ManagementSection.If you have questions about isolation distances not listed here, please contact the Minnesota Department of HealthWell Management Section.Questions?

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.
However, if you are confident that your tank is in good condition, the date of installation should provide you with an indication of how long it will endure.
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.
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?
Riser systems, which allow you to reach your tank from the ground level through a lid, are common in newer septic systems. 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 your system. When a tank cannot be accessible from the ground level, it will need to be dug up in order to determine if it requires pumping or not. In order to avoid the hassle of inspecting your septic system to see whether it need pumping, set up a timetable that has your system pumped every 2-3 years.
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?
In most cases, a septic system has a 1,500-gallon tank, which needs to be pumped around every two to three years for a household of four people. The likelihood of you needing to pump your septic system every five years is higher if you have less than four persons in your house. In order to determine the exact size of your tank, you should speak with your local health department. You should also speak with a septic system provider to determine how frequently your tank needs to be pumped based on the size of your family and the size of your tank.
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.
The drains in my home aren’t draining as quickly as they normally do. Does this have to do with my septic system?
Drains that are clogged and that empty slowly are not necessarily a big source of concern. Before presuming that there is an issue with your septic system, check sure that there isn’t anything obstructing your drain first. In the case of one plumbing fixture in your house that is draining slowly, it is likely due to clogging; however, if all of the drains in your home are slow or leave waste backed up, it is probable that your septic system requires inspection and may even require pumping.
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.
A blocked drainfield is likely the reason of your sluggish draining pipes, damp yard above your tank or drainfield, sewage stench coming from your yard, or tainted well water. 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.
4725.4450 – MN Rules Part
A water-supply well must be sited in an area with excellent surface drainage and at the highest practicable elevation possible to provide adequate water delivery. When at all feasible, water-supply wells should not be positioned on the same slope or in the same gradient as a source of pollution. A water-supply well must be erected as far away from a pollution source as is practicable, but not closer than the distances specified in this section. The isolation distances specified in this section are the shortest horizontal distances between the closest part of the upper termination of the water-supply well casing and the closest part of the contamination source, or the shortest vertical distance between the contamination source and the established ground surface, whichever is the shorter horizontal distance.
In the absence of complete removal of all pollutants from the source and complete removal of visibly contaminated soils from the site, the minimum isolation distances between a new well and a source of pollution that is no longer in use must be maintained.
A water-supply well must be at least the following dimensions:

In the event that you are considering acquiring or selling a home that is equipped with a septic system, you should be aware that there are a number of rules and compliance concerns that must be addressed in connection with real estate transactions involving septic systems. Minnesota law requires that a septic system be in compliance with certain standards before any land conveyance, including the sale, transfer, contract for deed, or other conveyance, can take place where there is a dwelling or a portion of land where a structure necessitates the use of a septic system.
The results of the inspection will be forwarded to the local environmental service department for a complete evaluation by the department’s staff.
Following is a list of the four distinct types of notices that a property owner might get following the completion of the septic system evaluation:
- This is the outcome that a property owner is looking for following a septic system examination. Certificate of compliance: If your septic system has been approved, it indicates that it fulfills all of the state and county regulations and criteria for subsurface sewage treatment systems. Non-conforming: The outcomes in this case are a little more complicated. Under the law, this means that “the existing system has less than the equivalent of 30.6 inches but at least 12 inches of vertical separation between the bottom of the distribution area and saturated soil level or bedrock, or any system that discharges sewage into a seepage pit, dry well, or leeching pit with at least 12 inches of vertical separation, or any individual sewage treatment system in use that is undersized relative to occupancy, or any system that does not meet the minimum vertical separation requirements, ” A system that is non-compliant is one that does not fulfill the state’s requirements for septic systems in terms of operation, treatment, and safety. Terrorism to the public health: If the inspection results indicate that your septic system poses an imminent threat to the public health, this means that the septic system is discharging into the ground surface, backing up into its own structure, or posing another type of situation that prevents it from being safe to use.
Homeowners do not have to sell their house immediately after having their septic system inspected because a certificate of conformity is valid for three years after it is issued. A certificate of non-conformity is also valid for three years and does not need the replacement of the system unless you add more bedrooms to the house. A non-compliant certificate indicates that the system must be improved within a year if it is located near a shore and within two years if it is not located near a coast.
To find out more, call Mike’s SepticMcKinley Sewer Services to discuss septic pumping service in Prior Lake, MN. A system that has been declared to pose a concern to public health must be improved within ten months of being discovered.
