A septic tank should always be “filled” to its normal liquid level, or the bottom of the outlet pipe which carries effluent to the absorption area. This normal liquid level is usually between 8” to 12” from the top of the tank on average (see picture at right).
- Keep septic tanks high: we don’t put the septic tank any deeper than necessary, since we are usually moving effluent from the septic tank to the drainfield also by gravity. Plumbers usually install sewer lines to slope down from inlet to outlet, at 1/8″ per foot to 1/4″ per foot of linear run of the waste pipe.
Should there be water in my leach field?
The water level should always be at the level of the drain line connecting the septic tank to the leaching field. If the water level is higher than the drain line, it means that the leaching field cannot hold any more water and it is backing up into the septic tank.
Should there be water in septic cleanout?
If the water is standing in the pipe or overflows out the cleanout, then you know that the problem is from that point out. At this point you can either call your favorite septic company, or dig up the tank lids yourself and check the water level and solids content in the tank.
Should there be water in septic distribution box?
A septic system distribution box should not be full of water. As effluent water leaves the septic tank towards the drain field, it first enters the distribution box. If the distribution box is full, there is a problem with clogged leach lines or a failing drain field.
How deep should leach drains be?
A standard leach line is considered to be three (3) feet wide and three (3) feet deep with a length as required.
Why is the ground wet around my septic tank?
If the grounds near your septic tank are wet, it likely points to a few sources. This could include a problem with your drain field, the subsurface piping used to remove contaminants and impurities from the liquid exiting the septic tank.
Why is there water above my septic tank?
The top of the septic tank is usually a few feet below the soil. If you see standing water above the drainfield or tank, your septic system is likely flooded. When you don’t see obvious standing water over the area, check the water level with a probe, or use an auger to dig down into the soil.
How high should the water level be in a septic tank?
A septic tank should always be “filled” to its normal liquid level, or the bottom of the outlet pipe which carries effluent to the absorption area. This normal liquid level is usually between 8” to 12” from the top of the tank on average (see picture at right).
Should I see water in my outside drain?
When looking in the drain, there should be flowing water and no visible signs of blockage. A blockage can be identified if the water in the drain is blocked and not flowing. Outside drains are often blocked up with leaves and other types of debris and dirt.
How do I know if my septic line is clogged?
Signs of Septic System Clogging: Water and sewage from toilets, drains and sinks backing up into your home. Bathtubs, showers, and sinks draining slowly. Gurgling sounds present in the plumbing system. Bad odors coming from the septic tank or drain field.
How deep should a distribution box be?
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 is a distribution box from a septic tank?
It’s usually somewhere near the edge of your drain field on the end that’s closest to your septic tank. Distribution boxes are usually only about 6 inches to 2 feet deep. This narrows your search, but you’ll need some other clues to help you find the exact location.
Can a distribution box get clogged?
One of the most common septic tank problems arises when the distribution box is damaged or clogged, preventing the flow of water from the septic tank into the drainfield. In most cases, a qualified plumber can fix this problem quickly and easily before it becomes a serious issue for the household septic tank system.
How deep should a septic tank be buried?
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. If you do not find the lid by probing, shallow excavation with a shovel along the tank’s perimeter should reveal the lid.
How far should drain field be from septic tank?
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.
Can a leach field be too deep?
Drain Field Depth The result is a drain field about 3 to 4 feet deep. Sometimes, however, a drain field may need to be a bit shallower and can result in drain pipes as close to the surface as 6 inches. Underground obstacles can cause this situation.
Septic Tank Design Depth – how deep should the septic tank be located
- When establishing a septic tank, you may ask a QUESTION or make a COMMENT regarding how deep the septic tank should be located.
InspectAPedia does not allow any form of conflict of interest. The sponsors, goods, and services described on this website are not affiliated with us in any way. Design depth for a septic tank: What are the most frequent depths to which septic tanks, cesspools, seepage pits, and drywells are buried? Is it necessary to locate the septic tank below the frost line in order to prevent it from freezing? Septic tanks are placed at a certain depth, and there are various elements that impact the actual depth to which a septic tank (or cesspool, drywell, or soak-pit) will be sunk, which are discussed below.

How Deep Should WePutthe Septic Tank at Original Installation?
Septic tanks may be built almost anywhere in the soil, regardless of its depth. When operating in a freezing climate, even in uninhabited homes, it is unlikely that the septic tank serving an occupied home or even an unoccupied one will freeze. This is due in part to latent heat received by the septic tank’s bottom from earth, in part to heat generated by bacteria in the septic tank, and in part to warm wastewater entering from a building served by the septic system, and in part to warm wastewater entering from the building served by the septic system.
You’ll kill the bacteria, damage the drainfield, and taint the surrounding ecosystem as a result of this.
Factors Determining Septic Tank Depth
The following are the primary elements that influence the actual depth at which a septic tank is likely to be buried (and, consequently, the depth to which you may have to dig to locate the septic tank) at a specific site:
- The depth to which the lowest sewage line departs the structure that the septic tank serves is referred to as the sewer line depth. Given that we often rely on gravity to transport sewage from a building to a septic tank, the tank will be lower than the waste line that exits the building that it serves. a spot where the contractor discovered site characteristics suited for burying a septic tank because of its form, rocks, and impediments If a location has bedrock or huge rocks that are near to the surface, the tank may be relocated
- The greater the distance between the tank and the structure, and the greater the depth of the tank if the system relies on gravity to carry sewage, the deeper the tank will be. We don’t place septic tanks any deeper than they need to be since we are normally transporting effluent from the septic tank to the drainfield by gravity as well as by pumping it out. Plumbers often build sewage lines to slope down from the inlet to the outlet at a rate of 1/8″ per foot to 1/4″ per foot of linear run of the waste pipe, depending on the kind of waste pipe. In order to avoid septic drainfield burial at an excessive depth, we must ensure that there is sufficient air in the soil, since the absence of oxygen deep in the soil will inhibit certain desired bacterial action (the aerobic bacteria) that is required to break down and process sewage. It is certainly possible to locate and position the septic tank anywhere, including uphill from the building, if a sewer ejector pump or grinder pump system is utilized to transport sewage from a structure to an underground storage tank. If a sewage effluent pump is used to transport septic effluent from the septic tank to the drainfield, we may, of course, locate the tank “downhill” from the drainfield as well
- But, if a sewage effluent pump is not utilized, we cannot. Growing grass: If the septic tank is just 2 or 3 inches below the surface of the earth, you might as well have left the top of the tank visible, because grass will not grow in such thin soil as you would expect. Adding 6″ to 12″ of backfill may be sufficient to allow grass to grow over the septic system
- However, this is a purely aesthetic issue and does not affect the system’s functionality. See SEPTIC SYSTEMS, OVERHAULED PLANTS
- Recommendations from the manufacturer: Some modern septic treatment system designs need the use of a skilled system operator to perform highly specified inspection and maintenance intervals. According to the information provided atBAT MEDIA SEPTIC PLANTS, BAT septic systems (biologically accelerated treatment) are maintained or examined at 6-month intervals, among other things. According to the maker of that technology (Jet Inc.), it is extremely critical that the finishing grade slope away from the facility when completed. In addition, the grade must be at least 1″ below the bottom of the access covers to be considered. (Jet retired in 2016)
A service riser should be put in deep septic tanks to provide access to the tank. Plungers are large-diameter “wells” that are installed over the entrance and/or outlet ports of a septic tank in order to provide simple access for tank pumping, inspection, and baffle repair. Plungers are also used for septic tank pumping, inspection, and baffle repair. If the septic tank is sunk more than a few inches below the surface of the earth, good practice calls for the installation of a septic riser, which is a high diameter pipe that allows for easy access to the septic tank for inspection and cleaning.

How Your Septic System Works
Underground wastewater treatment facilities, known as septic systems, are often employed in rural regions where there are no centralized sewage lines. They clean wastewater from residential plumbing, such as that produced by bathrooms, kitchen drains, and laundry, by combining natural processes with well-established technology. A conventional septic system is comprised of two components: a septic tank and a drainfield, often known as a soil absorption field. It is the septic tank’s job to decompose organic matter and to remove floatable stuff (such as oils and grease) and solids from wastewater.
Alternate treatment systems rely on pumps or gravity to assist septic tank effluent in trickling through a variety of media such as sand, organic matter (e.g., peat and sawdust), constructed wetlands, or other media to remove or neutralize pollutants such as pathogens that cause disease, nitrogen, phosphorus, and other contaminants.
Specifically, this is how a typical conventional septic system works:
- All of the water that leaves your home drains down a single main drainage pipe and into a septic tank. An underground, water-tight container, often composed of concrete, fiberglass, or polyethylene, serves as a septic system’s holding tank. Its function is to retain wastewater for a long enough period of time to allow particles to sink to the bottom and form sludge, while oil and grease float to the surface and produce scum. Sludge and scum are prevented from exiting the tank and moving into the drainfield region by compartments and a T-shaped outlet. After that, the liquid wastewater (effluent) exits the tank and flows into the drainfield. The drainfield is a shallow, covered hole dug in unsaturated soil that serves as a drainage system. Porous surfaces are used to release pretreated wastewater because they allow the wastewater to pass through the soil and into the groundwater. In the process of percolating through the soil, wastewater is accepted, treated, and dispersed by the soil, finally discharging into groundwater. Finally, if the drainfield becomes overburdened with too much liquid, it can flood, causing sewage to flow to the ground surface or resulting in toilet backups and sink backups. Finally, wastewater percolates into the soil, where it is naturally removed of harmful coliform bacteria, viruses, and nutrients. Coliform bacteria are a kind of bacteria that may be found in the intestines of humans and other warm-blooded animals, with humans being the most common host. As a result of human fecal contamination, it is a sign of this.
The Guadalupe-Blanco River Authority has built an animated, interactive model of how a residential septic system works, which you can view here.
Do you have a septic system?
It’s possible that you’re already aware that you have a septic system. If you are not sure, here are some tell-tale symptoms that you most likely are:
- You make use of well water. In your home, the water pipe that brings water into the house does not have a meter. In the case of a water bill or a property tax bill, you will see “$0.00 Sewer Amount Charged.” It is possible that your neighbors have a septic system
How to find your septic system
You can locate your septic system once you have confirmed that you have one by following these steps:
- Taking a look at the “as constructed” drawing of your house
- Making a visual inspection of your yard for lids and manhole covers
- Getting in touch with a septic system service provider for assistance in locating it
Failure symptoms: Mind the signs!
A bad odor is not necessarily the first indicator of a septic system that is failing to work properly. Any of the following signs should prompt you to seek expert assistance:
- Water backing up into the drains of homes and businesses
- It is especially noticeable in dry weather that the drainfield grass is bright green and spongy. The presence of standing water or muddy soil near your septic system or in your basement
- A strong stench emanating from the area surrounding the septic tank and drainfield
Managing waste: Household septic systems – Part 1
It is important to understand how a residential wastewater treatment system works in order to safeguard one’s own health and that of the environment. After it has been flushed down the toilet or sink drain, what happens to the waste water generated in your home? There are two alternatives: This waste water is either transported to a municipal waste water treatment facility where it is cleaned and returned to the environment, or it is collected and treated on the premises through a septic system before being returned to the environment.
- This accounts for more than a third of all households in the state of Michigan.
- There are two main components of a septic system: an absorption or drain field and a septic tank.
- The majority of tanks are double-chambered, which means that the tank is separated into two compartments.
- A pipe connects the drain field to the tank, which allows for easy drainage.
- Wastewater is discharged from the residence through the sewer line and into the septic tank.
- This is referred to as the scum layer.
- It is around two-thirds of the way up the tank from the bottom that a baffle or T-pipe is positioned.
The liquid waste, referred to as effluent, is introduced into the absorption field by gravity, which distributes the effluent uniformly across the rows of pipes.
It is recommended that the septic tank and drain field have sufficient capacity to retain two days’ worth of waste water, even during peak usage.
Calculate the size of your septic tank by entering the information in the box below.
For most septic tank sizes, 150 gallons per bedroom is used to calculate the appropriate size for the system.
The capacity of your septic tank should be sufficient to contain two days’ worth of effluent.
Which is more important: Amount for two days OR Septic tank capacity If the quantity of waste water generated in two days exceeds the capacity of your septic tank, you must either lower the amount of waste water generated or improve your system.
Home*A*Systbulletin WQ51 is a home automation system.
The amount of waste water that enters the system and the amount of water that may be absorbed by the soil define the size of the system.
Gravely or sandy-type soils cause waste water to pass through the soil too quickly for treatment to be effective.
Clay or compacted soils may retain water for an excessive amount of time before it is absorbed, causing the system to become anaerobic (without oxygen), resulting in bad smells and the possibility of system failure. Articles on MSUExtension that are related:

Everything You Need to Know About Your Septic Tank
What is a septic tank, and how does it work? A septic tank is a water-tight container that is often constructed of concrete, fiberglass, or polyethylene to prevent flooding (plastic). In fact, it is only one component of the entire septic system, which includes several other components such as a distribution box, pumps, float switches, aerators, filters, and other accessories. Septic systems are used to treat wastewater on-site in many rural and suburban areas that do not have access to centralized sewage systems.
The components of a conventional septic tank are depicted in the diagram below.
These are:
- The Tank: This is the water-tight tank into which wastewater from your house is sent once it has been collected. A hole, fracture, or any other structural damage should not be present. Access Ports: When a trained pumper comes to clean up your tank, they will utilize an access port. When it comes to tank cleaning, it is critical that the access port be large enough to allow the pumper to move the hose about within the tank properly. A common application for risers is to elevate septic tank access above ground level, eliminating the need to dig up your septic tank every time it has to be pumped. Last but not least, the access port should be securely secured with a child-resistant lid. It is vital for the protection of your family that septic tank lids are securely fastened with screws and that they are not cracked or damaged. Pipes for entering and exiting the septic tank: Wastewater from your house enters the septic tank through the intake pipe. After the particles have settled out, the effluent is discharged from the septic tank through the exit pipe and into the drainage field. There should be roughly 3 inches between the output pipe and the intake pipe. A baffle is fitted on the intake pipe within the tank, and it serves to keep the water out. It provides a variety of functions. Additionally, it helps to avoid the build-up of scum and its backup into the intake pipe It is also important for solids to settle in the tank that the input baffle be properly installed. When wastewater enters the septic tank, it should hit the entrance baffle, which will reduce the flow and prevent the tank from becoming agitated. This permits the contents of the septic tank to remain at rest, allowing the solids to sink to the bottom of the tank. The intake baffle can also prevent odorous odors from entering the sewage line and spreading throughout the home or business
- And It is even more crucial than the inlet baffle to have an exit baffle in place because it helps to prevent scum and other particles from flowing directly into the outflow pipe and eventually into the drain field. Gas Deflector/Effluent Filter: As gas bubbles climb to the top of a septic tank, they may bring sediments with them. This is why an effluent filter is used. A gas deflector prevents these solid-carrying gases from entering the output line by preventing them from entering. However, while not every septic tank is equipped with an effluent filter, it is strongly suggested as an additional safety to prevent particulates from entering your drain field.
Any of the above-mentioned components in your septic tank should be checked for damage or missing parts as soon as possible, and the problem should be resolved by a septic system specialist. What is the operation of a septic tank? Each and every drop of wastewater from your home is channeled via a main drainage pipe and into your septic tank. Solids are prevented from entering your drain field by using the septic tank, which is just a settling tank that serves as a filter. Ideally, the water should be kept in the tank for at least one day in order to enable time for the solids to settle.
- Heavy materials, such as dirt and digested waste, will sink to the bottom of the tank and form a sludge layer at the bottom of the tank.
- Effluent is the term used to describe the liquid that exists between the sludge and scum layers.
- It is critical that solids are given adequate time and space to settle before being used.
- In fact, the Pennsylvania Department of Environmental Protection mandates a minimum capacity of 900 gallons for any new septic tank installations in the state (the table below shows recommended septic tank capacities for different sized homes).
- Ideally, you should have your septic tank emptied every two to three years, according to the Pennsylvania Septage Management Association (PSMA).
- If a drain field has been ruined by a buildup of sediments, it might cost tens of thousands of dollars to rebuild it.
- It is important to understand that your septic tank must be completely filled with liquid in order to function properly.
- The septic tank diagram shown above depicts the correct operating level of a septic tank in a residential setting.
- The result is that whenever more wastewater is added to the tank, an equal amount of effluent will be discharged from the tank and drain into the drain field.
- The opposite is true if the liquid level is higher than the outlet line, which may indicate a blockage in a line downstream from the septic tank or in the drain field.
If you’re wondering if your septic tank is full, a qualified pumper will consider it “full” once solids have filled one-third of the tank’s capacity. This is the time of year when your septic tank will need to be pumped.
Septic System Guide: How It Works and How to Maintain It
As soon as you flush the toilet in most metropolitan locations, the waste is pumped out to the nearest sewage treatment facility. Garbage is processed at this factory, which separates it into two types of waste: water that is clean enough to be dumped into a river and solids known as residual waste. The remaining material is either disposed of in landfill or utilized as fertilizer. Septic systems, which are used in places where there aren’t any sewage treatment plants, provide a similar function, but on a much smaller scale.
What are Septic Tanks and How Do They Work?
Septic tanks are normally composed of concrete or heavyweight plastic and have a capacity of 1000 to 2000 gallons, depending on the manufacturer. In the tank, there are two chambers that are divided by a portion of a wall. The waste from the residence is channeled into the bigger room. Solids sink to the bottom of the chamber, and liquids make their way through a partial wall into the smaller second chamber, which is located above it. Anaerobic bacteria, which are found naturally in the environment, digest the solids and convert them into water, carbon dioxide, and a tiny amount of indigestible debris.
Septic Fields Distribute Liquid Effluent
The second chamber has an output pipe via which the liquid (known as effluent) from the tank is discharged to a disposal or leach field, depending on the situation. It is drained into the earth by a network of perforated pipes or through perforated plastic structures known as galleries, which are constructed of perforated plastic. It is common practice to lay the pipe or galleries in a bed of gravel, which aids in dispersing the liquid. During the course of the effluent’s percolation through the soil, the soil absorbs remaining bacteria and particles, resulting in water that is safe to drink by the time the water reaches the aquifer deeper down.
They are not much deeper than that since a large quantity of water escapes through evaporation or is transpired by grass growing above ground.
If you have sandy soils that drain too rapidly, you may not be able to treat the wastewater properly.
Sometimes the water cannot be disposed of properly because the natural soils include a high concentration of silt or clay.
Topsoil and grass are applied to the mound, which allows more water to leave through transpiration and evaporation than would otherwise be possible.
Septic Systems Rely on Gravity, Most of the Time
The majority of septic systems rely on gravity to transfer the liquid from the home to the tank and then to the field where it will be disposed of. However, due to the slope of the land, the tank or the field may need to be higher than the house in some instances. It is necessary to have a pump, or occasionally two pumps, in order for this to operate. A grinder pump, which liquefies sediments and is installed in a pit in the basement or crawlspace of the home, will be used if the tank is higher than the house.
Sewage pumps are essentially large sump pumps that are used for heavy-duty applications.
How to Treat Your Septic System
It is not necessary to do much to keep your septic system in good working order, other than cut the grass above it and keep the drainage area free of trees and plants with roots that may block it.
How Often Do You Need to Pump A Septic Tank?
You should have a septic provider pump out the particles from your tank every two years, at the absolute least. A manhole at the surface of the tank will provide the pump operator access, but older systems may necessitate digging a hole in the tank’s top so the pumping hatch can be exposed. Unless the tank is continuously pumped, sediments will build up in it and ultimately make their way into the leach field, clogging it. You’ll know it’s occurring because untreated effluent will rise to the surface of the tank and back up into the home, causing it to overflow.
Pumping the tank on a regular basis can ensure that the leach fields continue to work eternally.
What to Do if Your Septic System Fails
Pumps in a pumped septic system will ultimately fail, just as they will in any mechanical system. Most pumps are equipped with an alarm that sounds when the effluent level in the pit is greater than it should be, indicating that the pump has failed and has to be replaced. This is a job that should be left to the professionals. Visit the following website to locate a trusted list of installation and septic system service companies in your area:

It is rare for a homeowner to have to worry about their septic system because it is well-maintained and doesn’t cause problems. Simple maintenance, such as keeping the tank pumped and the lawn trimmed, should result in decades of trouble-free service.

What size of septic tank do I need?
Probably one of the last things on your mind when you are constructing a new house is the location of your septic system.
After all, shopping for tanks isn’t nearly as entertaining as shopping for cabinetry, appliances, and floor coverings. Although you would never brag about it, your guests will be aware if you do not have the proper septic tank placed in your home or business.
septic tanks for new home construction
The exact size of the septic tank is determined mostly by the square footage of the house and the number of people who will be living in it. The majority of home septic tanks have capacities ranging from 750 to 1,250 gallons. A 1000 gallon tank will most likely be required for a typical 3-bedroom home that is smaller than 2500 square feet in size. Of course, all of this is dependent on the number of people who live in the house as well as the amount of water and waste that will be disposed of through the plumbing system.
For the most accurate assessment of your septic tank needs, you should speak with an experienced and trustworthy sewer business representative.
planning your drainfield
Here are some helpful hints for deciding where to locate your drainfield when you’re designing it.
- Vehicles should not be allowed on or around the drainfield. Planting trees or anything else with deep roots along the bed of the drain field is not recommended. The roots jam the pipes on a regular basis. Downspouts and sump pumps should not be discharged into the septic system. Do not tamper with or change natural drainage features without first researching and evaluating the consequences of your actions on the drainage field. Do not construct extensions on top of the drain field or cover it with concrete, asphalt, or other materials. Create easy access to your septic tank cover by placing it near the entrance. Easy maintenance and inspection are made possible as a result. To aid with evaporation and erosion prevention, plant grass in the area.
a home addition may mean a new septic tank
Do not make any big additions or renovations to your house or company until you have had the size of your septic system assessed. If you want to build a house addition that is more than 10% of your total floor space, increases the number of rooms, or necessitates the installation of new plumbing, you will almost certainly need to expand your septic tank.
- For a home addition that will result in increased use of your septic system, your local health department will require a letter from you that has been signed and authorized by a representative of your local health department confirming that your new septic system is capable of accommodating the increase in wastewater. It is not recommended that you replace your septic system without the assistance of a certified and competent contractor.

Make sure you get your septic system professionally cleaned every 2 to 3 years, or more frequently if necessary, by an experienced and qualified expert
- If you have any reason to believe that there is an issue with your system, contact a professional. It is far preferable to catch anything early than than pay the price later. Maintain a record of all septic system repairs, inspections, and other activities
common septic questions
Here are some of the most frequently asked questions by our septic customers.
How do I determine the size of my septic tank?
If you have a rectangular tank, multiply the inner height by the length to get the overall height of the tank. In order to find out how many gallons your septic tank contains, divide the number by.1337.1337
How many bedrooms does a 500-gallon septic tank support?
The exact size of the septic tank is determined mostly by the square footage of the house and the number of people who will be living in it. The majority of home septic tanks have capacities ranging from 750 to 1,250 gallons. A 1000 gallon tank will most likely be required for a typical 3-bedroom home that is smaller than 2500 square feet in size.
How deep in the ground is a septic tank?
Your septic system is normally buried between four inches and four feet underground, depending on the climate.
3 THINGS TO KNOW ABOUT SEPTIC TANK BAFFLES
By Admin on November 12, 2020 Your efforts to live as environmentally conscious as possible, as a responsible homeowner, are likely already underway, with practices such as recycling, composting, and purchasing energy-efficient equipment among your list of accomplishments. As a septic tank owner, you want to be sure that anything you put into your tank and septic field is causing the least amount of ground contamination as is reasonably practicable. Fortunately, there are a number of modest improvements you can do immediately to make your septic system even more ecologically friendly than it already is.
- Have your septic tank inspected and pumped on a regular basis.
- A bigger septic tank with only a couple of people living in your house, for example, will not require pumping as frequently as a smaller septic tank or as a septic tank that must manage the waste products of multiple family members will require.
- When in doubt about how often to pump your septic tank, consult with a professional for advice.
- In addition to locating and repairing any damage, a professional can ensure that the septic field is in good working order and that your septic tank is functional, large enough to handle your family’s waste, and not causing any unwanted pollution in nearby ground water.
- Avoid flushing non-biodegradable items down the toilet or down the toilet.
- Items that are not biodegradable are unable to properly decompose in the septic tank and might cause the system to get clogged.
- In addition to causing issues in your house, septic system backups can damage ground water in the area surrounding your septic field.

grinds from a cup of coffee Even if you have a trash disposal, the food scraps that you flush down the drain and bring into your septic system may cause unanticipated harm to your plumbing system.
Food scraps can enhance the amounts of nitrogen and phosphorus in the wastewater, which can disturb the natural bacterial balance of the septic tank, among other things.
Water conservation should be practiced.
Exceedingly large amounts of water use will interfere with the normal flow of wastewater from your home into your septic tank.
Limiting the amount of time you spend in the shower and turning off the faucet while brushing your teeth, as well as purchasing a smaller dishwasher and washing machine that use less water, are all simple strategies to reduce water use in your home.
The following are some basic steps you can take to make your septic system more ecologically friendly: save water, maintain your septic system and tank, and recycle wastewater. To get answers to any of your septic tank-related issues, get in touch with the experts at Upstate Septic Tank, LLC.
5 Signs Your Septic Drainfield Has Stopped Working
Unlike municipal septic systems, which consist just of a subterranean tank that collects waste and water, residential septic systems are more complex. Water finally departs the tank through an outlet pipe and into a network of long perforated pipes known as the leech or drainfield after reaching the tank’s interior. The drainfield is equally as vital as, if not more so than, the septic tank in terms of wastewater treatment. In the event that this component of the system begins to fail, prompt action might mean the difference between relatively small repairs and a total drainfield replacement.
- Drainage is being slowed.
- As long as there is still any water in the pipes of the field, the drains in your home will continue to function, albeit at a slower rate.
- The presence of obstructions in the inlet or outlet pipe, as well as several other septic problems that are less difficult to resolve than drainfield problems, might result in delayed drainage.
- 2.
- You may detect puddles or spongy and mushy ground all over the place if you look closely.
- A backup occurs when the water level rises to a level that forces sewage up the input pipe and into the lowest drains in your house, which is known as a back up in the system.
- 3.
Drainfield leaks can provide visible consequences on the surface if the drainfield leaks at a higher rate than typical or contains decaying material that is meant to remain in the tank.
Returning Flow is the fourth step.
If you presume that the tank just need pumping, the service technician may discover water and sewage entering the tank from the outlet in a reverse flow, which would indicate that the tank requires more than pumping.
The presence of reverse flow from the drainfield is an obvious indication that you want jetting or pipe replacement services.
The Development of Odors In the end, you can utilize your sense of smell to detect indicators of drainfield issue.
Any sewage or toilet scents, even if they are weak and difficult to detect, signal that you should have a professional evaluate your home immediately.
This is the most effective way.
Whenever we observe a decrease in drainage capacity, we will inform you of the problem and your choices for resolving it before the system stops processing waste altogether.

SEPTIC SYSTEM articles are available for viewing here. Unless a municipality has installed a “on-site sewage disposal system,” often known as a septic system, each residence in such an area must treat its sewage on its own property.
One of the most commonly seen types of leach field is composed of a succession of perforated distribution pipes, each of which is situated within a gravel-filled absorption trench.
Leach Field
When used properly, a leach field (also known as a “drain field”) is a series of perforated pipes that are typically buried in gravel trenches 18 to 36 inches below grade — deep enough to avoid freezing, but close enough to the surface that air can reach the bacteria that further purify the effluent (see illustration below). As little as 6 inches might separate you from the ground surface, depending on your soil type and municipal regulations. It is customary to cover the perforated pipes with approximately two inches of gravel and a layer of topsoil that is 18 to 24 inches in depth.
- Grass is often sown above the ground.
- The leach field is comprised of rows of perforated pipes in gravel trenches that are used to spread wastewater over a vast area in order to further purify it.
- A bacteria-rich slime mat forms where the gravel meets the soil, and it is responsible for the majority of the water purification work.
- Despite the fact that wastewater freezes at a far lower temperature than pure water, freezing is still a hazard in cold areas.
- The leftover pathogens are converted into essential plant nutrients by these organisms, while sand, gravel, and soil filter out any solids that remain.
- If the system is operating effectively, the filtered wastewater will return to the aquifer as naturally clean water that is suitable for human consumption at this stage.
- Alternative systems may be permitted in situations when traditional leach fields are unable to function properly owing to poor soil conditions or a high water table.
These systems sometimes cost twice or three times as much as a regular system and require significantly more upkeep. Special systems may also be necessary in regions where there are flood plains, bodies of water, or other ecologically sensitive areas to protect against flooding.
SIZING THE LEACH FIELD
Using perforated pipes put in gravel-filled trenches, the drain field is sized to accommodate the number of beds in the house. In order for the system to function successfully, the leach field must be appropriately sized for the soil type and amount of wastewater, which is normally determined by the number of bedrooms in the house. In order for the liquid to seep into the soil, it must be permeable enough to do so. As a result, the denser the soil, the larger the leach field that is necessary.
- Better to have surplus capacity in your system than to have it cut too close to the bone.
- Septic tank backup into your house, pooling on the surface of the earth, or polluting local groundwater are all possibilities if the ground is incapable of absorbing the liquid.
- Dense clay soils will not absorb the liquid at a sufficient rate, resulting in a backlog.
- If the soil is mostly composed of coarse sand and gravel, it might drain at such a rapid rate that untreated sewage can poison the aquifer or damage surrounding bodies of water.
- Alternative systems may be permitted in situations when traditional leach fields are unable to function properly owing to poor soil conditions or a high water table.
- Near flood plains, bodies of water, and other ecologically sensitive places, special systems may also be necessary to protect people and property.
SEPTIC SYSTEM CAREMAINTENANCE REQUIRED
If you take good care of your system, you will be rewarded with years of trouble-free operation. Pumping the septic tank on a regular basis is necessary to remove the particles (sludge) and grease layer (scum) that have built up in the tank. The solids will ultimately overflow and spill into the leach field, decreasing its efficacy and diminishing its lifespan if this is not done. The rehabilitation of a clogged leach field is difficult, if not impossible; thus, constant pumping is essential!
Cooking fats, grease, and particles may also wash into the leach field if the tank is too small for the amount of water being used or if the tank is overcrowded on a regular basis.
Extra water from excessive residential consumption or yard drainage can overwhelm the system, transporting oil and particles into the leach field and causing it to overflow.
In addition, don’t try to complete a week’s worth of laundry for a family of five in a single day. This will assist you in keeping the load controlled and will also help to extend the life of your system. To minimize overburdening the system, the following measures should be taken:
- Distribute your washing loads and other high-water-use activities across the week
- And In the kitchen and bathroom, use low-flow appliances, faucets, and fixtures. Toilets, in general, are the source of the greatest amount of water use. Water should be diverted away from the leach field from the yard, gutters, and basement sump pumps.
In addition, refrain from flushing sediments, strong chemicals, and just about anything else down the toilet or sink other than biological waste and white toilet paper. Avoid using garbage disposals in the kitchen. If you really must have one, keep it for small non-meat bits only. Avoid flushing chemicals or paints down the toilet since many chemicals can destroy beneficial microorganisms or cause water contamination in the surrounding area. Avoid flushing the following down the toilet:
- Grease, fats, and animal scraps
- Paints, thinners, chemicals, and pharmaceuticals
- And a variety of other materials sanitary napkins, tampons, and other supplies Paper towels and disposable diapers are examples of such products. Egg shells, coffee grounds, and nut shells are all good options. Antibacterial soaps and antibiotics are available.
It is preferable to put grass over the leach field and to refrain from driving or parking in the vicinity. Excessive weight placed on top of the drain field might compress the earth, diminishing its efficiency as a drain field. Drain pipes can also become clogged by trees and plants with invasive roots. In order to prevent damage to the leach field, the following measures should be taken:
- Heavy machinery should not be driven, parked, or stored on top of the leach field (or septic tank). Placement of a deck, patio, pool, or any other sort of construction over the leach field is prohibited. Remove any large trees or other plants with deep roots from the leach field. Grass is the most effective groundcover.
Even with careful use and routine maintenance, however, leach fields are not guaranteed to survive indefinitely. It is inevitable that the soil will get saturated with dissolved elements from the wastewater, and that the soil will be unable to absorb any more incoming water. The presence of an odorous wet area over the leach field, as well as plumbing backups in the house, are frequently the first indicators that something is wrong. Many municipalities mandate septic system designs to incorporate a second “reserve drain field” in the case that the first field fails.
A well constructed and maintained system should last for at least 20 to 30 years, if not longer than that.

SEPTIC SYSTEM PERFORMANCE PROBLEMS
Poor original design, abuse, or physical damage, such as driving heavy trucks over the leach field, are the root causes of the majority of septic system issues. The following are examples of common situations that might cause a septic system to operate poorly: Plumbing in the home. obstructed or insufficient plumbing vents, a blockage between the home and the septic tank, or an insufficient pitch in the sewer line leading from the house are all possible causes. Sewage tank to leach field connection Septic tank and leach field blockage caused by a closed or damaged tank outlet, a plugged line leading to the leach field caused by tree roots, or a blockage caused by sediments that overflowed from the tank Piping in the leach field.
Most of the time, tree roots do not make their way through the gravel bed and into the perforated pipe.
Reduced flows, achieved through the use of flow restrictors and low-flow faucets and fixtures, may be beneficial.
Because of the seasonal high water table, the soil around the trenches might get saturated, reducing the soil’s ability to absorb wastewater.
This may frequently be remedied by adding subsurface drains or curtain drains to intercept the water flow into the leach field region and to lower the water table in the immediate area around the drainage system.
