Septic drain field – Wikipedia
What is the difference between a septic tank and a cesspit?
- Septic tanks are part of a sewage treatment system and have an outlet that runs to a soakaway, typically they require emptying every 12 months. A cesspit or cesspool is a holding tank without an outlet. It is not part of a sewage treatment system it is just used for the storage of waste.
How does a septic seepage pit work?
Seepage pits are dug vertically into the ground to collect the gray and black water from a septic tank. The vertical orientation of a seepage pit is the most important difference between it and a leaching field. Most seepage pits are built so that at least four to six feet of soil covers the top of the pit.
How long do septic seepage pits last?
Typically, pits last about 15-20 years, but this is due to abuse and improper maintenance. Both compartments of the septic tanks must be pumped every 2-5 years to limit the amount of solids entering the seepage pit. This will ensure a long life for your septic system.
Can a seepage pit be repaired?
Damaged or Collapsing Drywells, Cesspools, or Seepage Pits If only the top were damaged it could be replaced. If the sides of the drywell were damaged on a site-built pit (such as one constructed of large stones or of concrete blocks), it may need to be rebuilt.
How does a seepage bed work?
In a gravity seepage bed design, effluent trickles through holes in perforated sewer pipe (usually 4″) into a bed of drain rock. The perforated sewer pipe is installed dead-level on the drain rock.
How do you unclog a seepage pit?
Can Anything Unclog an Old Septic Drain Field?
- Shock the System With Bacteria. A septic system bacteria packet can help clean out a clogged drain field by allowing waste material to break down and drain through.
- Reduce Water Usage.
- Avoid Harsh Chemicals.
- Change to Gentler Toilet Paper and Soap.
- Contact a Septic Professional.
How deep is a seepage pit?
Seepage pits are typically no deeper than 30 feet due to construction complexities. If the system needs more than 30 feet of pit depth, split the depth as evenly as possible between 2 or more seepage pits. For example, a system that needs 75 feet of pits should have 3 pits, each 25 feet deep.
What is a seepage pit?
noun. a pit that is lined with a porous, mortarless masonry wall in which effluent from a septic tank is collected for gradual seepage into the ground, sometimes used as a substitute for a drainfield.
Can you pump a seepage pit?
Seepage Pits can only be pumped if a riser has been installed. Leachfields can not be pumped. Knowing the capacity will help determine how many loads needed to properly pump your system.
Is a seepage pit the same as a cesspool?
A seepage pit is similar to a cesspool in construction. It consists of a large pit lined with concrete rings, or porous masonry block to support the walls of the pit, and a surrounding bed of gravel. The difference is that only effluent that has come from a septic tank enters a seepage pit.
How do you unclog a drywell?
The best solution to clogged drywells involves scrapping the walls thoroughly to get sufficient water outflow, which goes a long way to drain the basin dry. If your drywell can drain well enough, it makes it easy to do further cleaning.
How long does a drywell last?
If properly maintained, a dry well can work effectively for more than 30 years. The best way to maintain a dry well is to inspect it four times a year, as well as after every storm with accumulated rainfall over an inch.
How does a septic drywell work?
The wastewater flows via a pipe into the drywell, usually a tall concrete cylinder that has holes in the sides and an open bottom, covered in soil. The wastewater then seeps out into the surrounding soil, which filters the effluent.
What are the signs that your septic tank is full?
Here are some of the most common warning signs that you have a full septic tank:
- Your Drains Are Taking Forever.
- Standing Water Over Your Septic Tank.
- Bad Smells Coming From Your Yard.
- You Hear Gurgling Water.
- You Have A Sewage Backup.
- How often should you empty your septic tank?
How do you tell if your septic tank is full?
How to tell your septic tank is full and needs emptying
- Pooling water.
- Slow drains.
- An overly healthy lawn.
- Sewer backup.
- Gurgling Pipes.
- Trouble Flushing.
Why is my septic tank foaming?
Phosphates that pass through the septic system due to improper design can enter surface water, causing very high growth rates of algae. Surfactants typically cause foaming or suds in water.
3 Types of Septic Seepage Pits You Really Need to Know About!
If you’re thinking about installing a septic tank, you’ll want to learn everything you can about seepage pits. You’ll also have to make a decision between three different styles of septic seepage pits. That is exactly what we are going to demonstrate to you!
What is a Seepage Pit?
When it comes down to it, seepage pits are simply a lined hole in the ground that gathers water and allows it to be spread and absorbed slowly into the surrounding soil. Stone, brick, wood, or concrete might be used to line the inside of the pit. A septic seepage pit is used to dispose of trash that is considered “clean” (water that is free of solids or germ-laden material). Various fixtures, such as showers, restrooms, bathtubs, washing machines, and other fixtures that release uncontaminated wastewater can be linked to these pits.
Cesspits, soak pits, latrine pits, dry wells, and septic seep pits are all terms for seepage pits that are used in septic systems.
It illustrates the overall structure of a seepage pit as well as the inspection pipe, the outflow pipe from the septic tank, and the outlet pipe to other pits, if any are required.
PRO TIP: Check with your local health or building agency first before deciding to use one of these services.
If at all feasible, keep the hole as shallow as possible since the walls of a deep trench might collapse and smother the digger.
3 Kinds of Seepage Pits
This form of seepage pit is extensively utilized, and it is also reasonably simple to put up. It’s made up of hollow-core masonry blocks, which are lightweight. The core is responsible for facilitating the movement of water out of the hole. Solid blocks, or even regular bricks, can be used in their place, as long as sufficient space is left between them to allow the water to soak into the soil. The cover, which is constructed of precast concrete and may weigh up to 500 pounds, should be placed by a professional because of its weight.
The majority of seepage pits never need to be examined.
2. Stone-filled Dry Well
A dry well with stone filling is the most straightforward of all seepage pits. It consists of a large pit totally filled with rocks of varying sizes and shapes. Water from an outdoor shower or a swimming pool may be absorbed using this method, which is particularly effective for little volumes of pure water.
However, the pace at which it absorbs is restricted. This means that it is not adequate to take a huge volume of water released by a clothes washer as an illustration of this. An illustration of a seepage pit: a dry well with stones in it
3. Drum of Precast Concrete Rings
Pit liners such as this one are available in diameters ranging from 4 to 8 feet and are offered as interlocking rings. The pit’s tapered entrances allow water to flow out while also preventing muck and debris from seeping into the pit. The rings, which stand around 3 feet tall and 3 to 4 inches thick, weigh more than a half-ton. As a result, unless you have the necessary personnel and tools to do so yourself, it should be properly installed. A drum of precast concrete rings used as a seepage pit is one example.
Tips for Seepage Pit Builders
Once you’ve determined that the usage of these pits is permitted under local restrictions, you’ll be ready to get started. No matter what kind of structure you construct, there are certain general guidelines to keep in mind.
- A seepage pit should be located at least 100 feet away from the nearest water well, 20 feet away from any structures, and 10 feet away from the boundary of the property. Ideally, there should be no obstructions between the house and the pit
- It should be at least 2 feet above ground water and 5 feet above any impermeable bedrock. It is possible to gain important insight into the character of the soil in your region by examining the strata of local road cuttings, stream embankments, and excavations for building foundations. It is possible that the soil maps of agriculture regions issued by the United States Department of Agriculture will be a more credible source of information. The ideal soil for drainage is sandy
- It crumbles quickly and breaks up into clods when it rains. Nonabsorbent soils are often those that are thick, hard, dry, dull gray, or mottled in appearance. Turning up shovelfuls of soil at several spots throughout your yard will allow you to assess the soil condition. When you select a location that appears to be acceptable, dig a test hole and conduct some experiments
- It is better to construct the structure on the side of a slope that runs down from the home. Gravity is able to assist with drainage as a result of this. Do not construct a seepage pit in an area where rainwater collects in puddles. The average clothes washer — the device most usually linked with a seepage pit — releases 44 gallons of water every load of laundry. Design the pit to have a capacity of 200 gallons to accommodate numerous loads every washday while also preventing overflow during strong rains and winter freezes, which can occur. Those are the occasions when absorption is less effective.
A septic seepage pit is not a simple undertaking to complete. It requires time and effort to do thorough study and examination of your soil, as well as a lot of strength to complete the heavy manual labor required. However, if you like the notion of living off the grid in the most natural way possible, a septic seepage pit is the ideal project for your way of living.

Septic System Seepage Pits
An underground well lined with porous masonry into which household waste is discharged from a septic tank and collected for slow seepage into the earth is known as a seepage pit, and it is occasionally used as a substitute for a drain field. In areas where there is no connection to the municipal sewage system or where a traditional septic system would not work adequately due to soil characteristics or a lack of available space, seepage pits were developed for usage. In many cases, there were no other options available for disposing of household garbage other than burning it.
The following is an illustration of how the system operates: Because of concerns regarding ground water contamination, the usage of seepage pits in Jefferson County was discontinued in October 1991.
After the dwelling was linked to the sanitary sewage system, the seepage system (pit) was detached from the house and, in many cases, was left in the ground to collect rainwater.
It has happened many times that the lids have gotten obscured by grass and are no longer visible.

What Is a Seepage Pit? – First Quality Environmental
Homeowners who have septic tanks may occasionally have seepage pits instead of leach fields in their backyards. It is critical for homeowners to understand how these wastewater treatment systems operate so that they can identify problems and seek expert assistance when necessary. Here is a tutorial that will give you some insight into what seepage pits are and what they do.
What Does a Seepage Pit Do?
Seepage pits are vertical concrete tanks that are built six to ten feet below ground level to collect seepage. Water collection tanks are typically several feet wide and are used to collect both black and grey water from the wastewater treatment system. Dishwater, bathwater, toilet effluent, and sewage are all collected in one container. These materials are mixed with a biomat of anaerobic bacteria, which consumes the organic waste while allowing the residual fluid to flow through the rocks at the bottom of the seepage pit, creating a biofilm.
Best Practices for Seepage Pits
Homeowners must have their wastewater treatment systems inspected on a regular basis to ensure that the seepage pit biomat does not get excessively thick. If these colonies of bacteria become too large, they may prevent grey and black water from draining into the soil and instead generate a backup into the residence, causing it to overflow. Professionals should backwash the pit on a regular basis to eliminate any buildup that has accumulated there at the bottom. In addition, keep an eye on what is going down the drains.
Rather than flushing disposable diapers, wipes, and feminine hygiene items down the toilet, place them in the garbage to prevent clogging septic plumbing.
Over the course of more than 18 years, they have built a reputation for providing high-quality services that help to preserve Hawaii’s distinctive natural environment.
A seepage pit is nothing more than a collection of pipes. It is constructed in the same manner as a well. In fact, when you gaze into one, it seems to be exactly like a well. Seepage pits are generally 5-7 feet in diameter and ranging from 15-40 feet deep, depending on the soil quality. Despite the fact that the pit’s physical walls are just 4 feet in diameter, the surrounding area is completely covered with gravel. Increased drainage is made possible by the gravel, which also helps to prevent clogging caused by excessive dirt contact with the walls.
- Pits can live for up to 40-60 years if they are maintained properly in septic tanks.
- Every 2-5 years, both compartments of the septic tank must be pumped out in order to keep the amount of sediments entering the seepage pit to a minimum.
- Another helpful tip is to add enzymes, sometimes known as “Bacteria,” to the tank, which will aid in the breakdown of the sediments.
- Which is better, a seepage pit or a cesspool?
- Overall, they are built in the same manner as one another.
- Septic tank cesspool: A pit that served as the only component of a septic tank system.
The use of cesspools was prevalent until the 1970s, when local governments started to compel the installation of a septic system consisting of a tank and a drain field. A seepage pit is a component of a septic system that is located after the septic tank and collects waste.
Cesspools and Seepage Pits
Sewage ponds and seepage pits were the forerunners of the modern-day septic system, which was invented in the 1800s. Especially in older homes that have not been sold in the previous 100 years, it is possible that these systems are still operational. So, what exactly is a cesspool and a seepage pit, exactly?
The cesspool is considered to be the precursor of the contemporary septic system. The cesspool is nothing more than a vertical trench excavated into the ground. This pit is bordered with a porous cement, block, or stone that allows water to pass through it. Gravel is used to fill in the spaces between the liner and the ground. The cesspool is where the wastewater from the house is routed. Solids settle to the bottom of the tank, where they are partially digested by bacteria and microorganisms that naturally reside in the tank’s bottom.
Cesspools are no longer the most effective means of disposing of domestic wastewater in today’s world.
Avoiding dumping oil and food down the drain will assist to maintain it in good operating order for a longer period of time.
Many individuals make the mistake of confusing cesspools with seepage pits. They each have a distinct function when it comes to wastewater treatment. In the building industry, a seepage pit is analogous to a cesspool. It comprises of a big pit that is lined with concrete rings or porous masonry block to support the pit’s walls, as well as a gravel bed surrounding it. The difference is that only effluent from a septic tank may be used to fill a seepage pit and not any other type of wastewater.
Once the water enters the seepage pit, it is temporarily kept there until it gradually seeps through the walls and into the surrounding soil and becomes a source of contamination.
Seepage pits are not as effective at treating wastewater as drainfields or soil absorption beds are at treating it.
Due to the fact that they are both closer to the water table, they do not safeguard our groundwater to the same extent as contemporary septic systems do.

How A Septic System Works
WHAT ARE SEPTIC TANKS AND HOW DO THEY WORK? In the septic tank, sediments build and are progressively broken down by bacterial activity as they settle to the bottom of the tank. A little amount of solid waste is really liquefied by this “natural bacterial breakdown,” but the vast majority of the trash gathers at the bottom of the tank as a layer of sludge and accumulates there. Additionally, a tiny amount of this waste (mainly fats and oils) floats to the top of the tank, forming a layer of semi-solid scum on the surface of the water.
Metropolitan residents (who have never had the pleasure of managing a septic system, or who have never waddled through their leachfields, or who never even had the fun of pumping out their systems) just flush their toilets and “away go difficulties down the drain.” The maintenance and operation of the wastewater treatment facility adjacent to our property, referred known as “the septic system,” have been required of those of us who live in more rural locations.
- Septic tanks are often connected to a drainage field or seepage pit of some sort.
- However, if it is left unattended for an extended period of time, it might back up and obstruct the drainage field.
- A COMPLETE LIST OF THE COMPONENTS OF SEWAGE TREATMENT SYSTEMSA House sewers, septic tanks, distribution boxes, and absorption fields or seepage pits are all common components of a conventional domestic sewage treatment system.
- In the absence of adequate treatment, untreated liquid household wastes (sewage) may soon block your absorption field, causing it to overflow.
- Upon entering the septic tank, the heavy contents drop to the bottom, while the lighter solids such as fats and greases partially degrade and rise to the surface where they produce a layer of scum.
- Septic tanks do not eradicate microorganisms, and as a result, the waste that is released cannot be regarded as safe for human consumption.
- It is critical that each trench or pit receives an equivalent quantity of water flow to function properly.
a system of shallow ditches partially filled with a bed of washed gravel or crushed stone, into which perforated or open joint pipe is installed.
The size and construction of the subsurface absorption field must be done correctly.
Cesspools – Cesspools function in a similar way as septic systems.
These can also get clogged as a result of excessive use as well as the introduction of detergents and other materials that slow down the bacterial action.
Pumping out will only provide temporary relief to the system.
MAINTENANCES Due to the fact that sediments will continue to accumulate at the bottom of the tank, it is critical that the “septic tank be pumped out on a regular basis.” Keep in mind that sludge is not biodegradable.
The frequency at which wastewater will be pumped out will be determined mostly by the volume of wastewater that passes through the system each day.
The more solid waste that is disposed of into the system, the faster the tank will fill up with water.
That is why it is recommended not to utilize a trash disposal in a septic tank system, and why water should not be left running in sinks or toilets without being used.
This will soon block the drainage pipes as well as the soil into which the pipes discharge their waste.
It is the bacteria’s responsibility to digest any organic waste stuff that accumulates in the system.
It becomes suffocating, and normal digestion will not take place.
Because to the usage of large amounts of detergents, laundry waste, bleach, home chemicals, and caustic drain openers, bacteria are being killed or overwhelmed in the environment.
Items that are not biodegradable are disposed of in the system (plastics etc.).
There are too many people utilizing a system that is too small, insufficient, or malfunctioning.
Enzymes are nothing more than a catalyst for the growth of microorganisms.
It is recommended that you supplement your system with “100 percent Natural LIVE ADULT BACTERIA” on a regular basis.
Make an appointment with your septic specialist.
Generally speaking, a facultative bacterium is one that may be used in both environments where there is air and environments where there is no air (anaerobic situations).
REGULATIONS AT THE LOCAL AND STATE LEVELS In recent years, as communities have grown more crowded and as people have become more aware of the influence of one home on another, regulatory authorities have begun to place greater emphasis on the correct care of each individual property.
Rather of leaving it up to the individual homeowner to determine how frequently to clean and pump their system, an increasing number of towns are implementing rules.
If an existing system malfunctions, or if a new house is being built, several jurisdictions have begun putting stricter limitations on the sorts of systems that may be used in certain situations.
With so many systems in regular use, the majority of which are older versions of poorer design, there has been growing concern that inadequately maintained systems would pollute groundwater sources or that the health of one’s own family may be compromised as a result of this.

Your home’s septic tank and sewer lines must be properly designed, installed, and maintained on a regular basis in order for them to continue to perform as they should and for the septic tank and pipes to have the longest possible life expectancy. It is vital to do routine maintenance on your septic tank in order to keep unclean, foul-smelling smells and germs from endangering the health of your family and keeping the local groundwater clear of sewage pollution. Proper maintenance and regular pumping of the septic tank system greatly reduces the risk of contamination to the surrounding well and ground water, and may save you from having to pay for costly septic system repairs or a complete septic system replacement.
Simply disregarding minor and typical problems with your septic system will not result in any savings in the long run!
How a Septic System works
The operation of a septic system is dependent on the configuration of the system and the location of the sewer system that transports waste and sewer water to the septic system. The septic tank is divided into two portions. The first portion is where the waste enters from a house’s sewage system or from another sort of structure in the neighborhood. Natural bacteria from our own bodies break down the waste in the first tank, and here is where the process begins. The second phase of the system is designed to allow the sewage water to seep down via a configuration of gravel, sand, and other filtering materials before being dispersed back into the earth.
Septic tank systems consist of two basic components:
The septic tank is number one on the list. (2) Septic drainfields/leaching fields, as well as dry wells and seepage pits
Concrete Septic Tanks
The waste water from your home is sent via thesewer works and into the septic system. In addition to holding waste water, the concrete septic tank is intended to enable heavy sediments and materials to settle and collect at the bottom of the septic tank. Solids are gradually degraded by microorganisms within the septic tank, resulting in the formation of sludge. Grease and other light materials float to the top of the septic tank, where they combine to produce a layer of scum on the surface of the wastewater, causing it to overflow.
Dual Compartment Concrete Tanks
The middle of the concrete septic tank is often split into two compartments by a partly concrete wall, which is common in newer types of concrete septic systems.
In this way, it is possible to prevent sewer sludge from being forced through the baffle and into the drainfield / dry well or the sewage treatment plant. Modern septic tank systems are additionally equipped with two manhole covers, one above each baffle, which are located above each baffle.
Drainfield (leaching field)
From the septic tank to the distribution box, a sewage line connects the two. Upon entering the distribution box, the waste water is routed into one or more perforated pipes that are installed in trenches that are filled with gravel. This is referred to as the septic systemdrainfield, which is also known as the aleaching fieldor trench. The wastewater gently seeps (infiltrates) into the earth here as it leaves the drainfield. Dissolved pollutants and bacteria in sewage water are trapped or absorbed by the ground, and microorganisms breakdown the wastes and bacteria that have been trapped.
New house development often includes the installation of trench septic systems, which are the most frequent form of system.
A seepage pit, sometimes known as a dry well, is a type of alternative to the more typical drainfields or leaching fields that are used. A pre-cast concrete tank with holes in the walls is used as a septic system in this configuration. Wastewater flows from the septic tank through the sewage works into the tank. Gravelor rocks surround the dry well, which is itself encircled bygravelor rocks. Older dry wells are often composed of a pit surrounded by open-jointed masonry or stone walls. It is possible that wastewater will seep through the holes or seams into the surrounding soil.
Possible Signs of Trouble
Slow drains and standing water are some of the most frequent indicators of a problem with your sewer system. Other signs include foul aromas coming from your drain field and gurgling sounds coming from your septic system. It is possible that sewer scents emanating from a septic system are coming from the septic tank itself or from the field line. If your septic system is congested and backing up, it might cause your drains to gurgle. An overflowing septic tank system is indicated by the presence of standing water above your field line.
Your septic system has not been cleaned or pumped out in the past five years.
Even though the septic system looks to be in good functioning order, sewage sludge may have accumulated to the point where wastewater is released without having had enough time to cleanse and settle the particles in the tank. A clogged drainfield or sewage contamination of groundwater may arise from this condition.
A wet area or standing water occurs above the drainfield.
This problem can arise when sewage sludge particles block the drainfield, when roots produce damaged pipes that prevent the waste water from distributing over the whole drainfield, or when water use in the house exceeds the capacity of the system on a regular basis, among other reasons. As a result of these conditions, waste water is unable to pass through the soil as it should and instead comes to the surface where it poses a major health concern as well as odor problems for surrounding residents.
Toilets are running slowly or water is coming backup.
In this case, clogged drainfields can occur when sewage sludge particles block the drainfield, roots cause damaged pipes that prevent waste water from distributing through the whole drainfield, or when water use in a home exceeds the system’s capacity on a regular basis.
As a result of these conditions, waste water is unable to pass through the soil as it should and instead comes to the surface where it poses a major health concern as well as odor issues.
Septic odors in the house, around the septic tank and drainfield, or from vent pipes.
Unless anything is wrong with the septic tank system, there should be no unusual aromas coming from it. There might be an issue with the system if there are any aromas coming from the tank or system. This could be an extremely early warning indication that anything is wrong with the system.
Septic Maintenance: How to Keep a Septic System Working
It is possible that sewer sludge will accumulate at the bottom of your septic tank over time, depending on the size of your home. Because of the buildup of waste in the sewer system, it can ultimately overflow into the distribution box and drainfield, clogging the distribution pipes quickly. In addition to being potentially detrimental to the environment and your family’s health, a blocked septic system may also result in an extremely expensive plumbing repair bill.
Install Septic Risers and Inspection Pipes.
Access to the septic tank and system is important in order to guarantee that routine maintenance may be conducted without undue inconvenience. When septic tanks are located below ground level, it is highly recommended to install septicrisers. Septic tank risers are devices that extend the tank manhole cover to or close to the surface. Raisers will make accessing the tank much easier if you need to do so during the colder months. Plastic or concrete septic risers are the most commonly used materials.
Have your Septic System regularly Pumped.
The amount of sewage sludge that accumulates at the bottom of your septic tank will vary depending on the number of people that live in your home, and the size of your septic tank. sewage treatment facilities On average, a septic system should be pumped out every 3 to 5 years, or when one-third of the septic tank is full with sewage sludge, depending on the circumstances. Some states have regulations about how often a septic tank must be emptied out. Generally speaking, the optimum time to have your septic system drained is between the months of early summer and early fall.
Springtime groundwater levels can occasionally build up to the point that they exert pressure on the underside of an empty septic tank, forcing it upward and sometimes out of the ground.
Taking good care of your drainfield.
For the most part, maintaining a drainfield is straightforward, but there are a few considerations to bear in mind. The drainfield region over the gravel field should have a thick layer of grass covering the ground surface. You should maintain this patch well ventilated and expose it to sufficient sunshine to encourage evaporation of moisture.
Because covering the drainfield bed will prevent oxygen from reaching the soil, it is not recommended to construct structures on top of drainfields. It is necessary to provide oxygen to the microorganisms responsible for digesting the wastewater in order for them to survive and operate properly.

How a Septic System Works
|The septic system is a sewage treatment and disposal system.A basic system consists of a septic tank and drainage area. All flows from the house are directed by way of a main sewer line to the septic tank. 40% of household sewage is from the toilet, 30% is from bathing, 15% is from laundry and 10% is from the kitchen.|
What is a Septic Tank?The septic tank is a watertight chamber constructed of concrete or poly material. An average size is approximately 1000 gallons to 1500 gallons in capacity. Most septic tanks have one or two compartments. Two compartment tanks, or two single compartment tanks in series, provide better settling of the solids.Each septic tank has an inspection port over each baffle as well as a manhole access port. The manhole lid needs to be accessed for the tank to be pumped. These can be found at or below the ground surface. Typically you will find 4” diameter plastic lids at the ground surface that are the inspection ports over either of the baffles on the tank and not where the tank is to be pumped through.The baffles of the tank are one of the most important components in the septic tank. The inlet baffle forces the wastewater from the sewer line down into the tank instead of across the surface of the tank and into the outlet pipe leading to the absorption area. The outlet baffle prevents the scum layer from moving into the soil absorption area. In a properly functioning septic tank the solids and sludge settle to the bottom and accumulate, scum (lightweight materials including paper, fats and greases) rises to the surface and the effluent (liquid) in the tank existing between those layers overflows to the absorption area.
|The absorption area uses the ability of the stone and soil to filter and treat the remaining effluent. Examples of absorption areas are seepage beds, trenches, sand mounds or older cesspools / seepage pits. A cesspool is a block walled dirt bottom pit. Cesspools are no longer an installation choice but there are many properties that still have functioning cesspools. Odors and gasses from the septic system, that are always present, are vented through pipes on the house roof.For further information: -On Lot Sewage System Owner Manual -A Homeowner’s Guide to Septic Systems – by EPA|
How Does a Septic Tank Work?
Mr. Fix-It-Up-For-The-Family You may save a lot of money if you understand how a sewage treatment system works—and what can go wrong—so that you can handle your own septic system maintenance.
How does a septic tank work?
Pumping the tank on a regular basis eliminates sludge and scum, which helps to keep a septic system in good working order. It is possible for a well-designed and well built septic system to last for decades, or it might collapse in a matter of years. It is entirely up to you as long as you can answer the question of how do septic tanks function. Healthy septic systems are very inexpensive to maintain, but digging up and replacing a septic system that has completely collapsed may easily cost tens of thousands in labor and material costs.
It’s critical to understand how a septic tank works in order to maintain one.
Let’s take a look below ground and observe what happens in a properly operating septic system, shall we?
Understand that a septic system is a cafeteria for bacteria
Bacteria are responsible for the proper operation of a septic system. They decompose garbage, resulting in water that is clean enough to safely trickle down into the earth’s surface. The entire system is set up to keep bacteria healthy and busy at all times. Some of them reside in the tank, but the majority of them are found in the drain field. 1. The septic tank is the final destination for all waste. 2. The majority of the tank is filled with watery waste, referred to as “effluent.” Anaerobic bacteria begin to break down the organic matter in the effluent as soon as it enters the system.
- A layer of sludge settles to the bottom of the container.
- Scum is mostly constituted of fats, greases, and oils, among other substances.
- Grease and oils float to the surface of the water.
- (5) A filter stops the majority of particles from reaching the exit pipe.
- The effluent is discharged into the drain field.
- Effluent is allowed to leak into the surrounding gravel because of holes in the drain septic field pipe.
- The garbage is completely decomposed by aerobic bacteria found in gravel and dirt.
- Potable water seeps into the groundwater and aquifer system from the surface.
Septic Tank Clean Out: Don’t abuse the system
Septic systems that have been correctly planned and constructed require just occasional ‘pumping’ to remove the sludge and scum that has built up inside the tank.
However, if you don’t understand how a septic tank works, you may unintentionally hurt or even destroy the system.
- Drains are used to dispose of waste that decomposes slowly (or not at all). Cigarette butts, diapers, and coffee grounds are all known to cause issues. Garbage disposers, if utilized excessively, can introduce an excessive amount of solid waste into the system. Lint from synthetic fibers is emitted from washing machine lint traps. This substance is not degraded by bacteria in the tank and drain septic field. Bacteria are killed by chemicals found in the home, such as disinfecting cleansers and antibacterial soaps. The majority of systems are capable of withstanding limited usage of these goods, but the less you use them, the better. When a large amount of wastewater is produced in a short period of time, the tank is flushed away too quickly. When there is too much sludge, bacteria’s capacity to break down waste is reduced. Sludge can also overflow into the drain field if there is too much of it. Sludge or scum obstructs the flow of water via a pipe. It is possible for tree and shrub roots to obstruct and cause harm to a drain field. Compacted soil and gravel prevent wastewater from seeping into the ground and deprive germs of oxygen. Most of the time, this is caused by vehicles driving or parking on the drain field.
Get your tank pumped…
Your tank must be emptied on a regular basis by a professional. Pumping eliminates the accumulation of sludge and scum that has accumulated in the tank, which has caused the bacterial action to be slowed. If you have a large tank, it may be necessary to pump it once a year; but, depending on the size of your tank and the quantity of waste you send through the system, you may go two or three years between pumpings. Inquire with your inspector about an approximate guideline for how frequently your tank should be pumped.
…but don’t hire a pumper until you need it
Inspections and pumping should be performed on a regular basis. However, if you’re not afraid of getting your hands dirty, you may verify the sludge level yourself with a gadget known as The Sludge Judge. It ranges in price from $100 to $125 and is commonly accessible on the internet. Once you’ve verified that your tank is one-third full with sludge, you should contact a professional to come out and pump it out completely.
Install an effluent filter in your septic system
Garbage from your home accumulates into three distinct strata. The septic filter is responsible for preventing blockage of the drain field pipes.
Septic tank filter close-up
The septic tank filter is responsible for capturing suspended particles that may otherwise block the drain field pipes. Obtain an effluent filter for your tank from your contractor and place it on the outflow pipe of your tank. (It will most likely cost between $50 and $100, plus labor.) This device, which helps to prevent sediments from entering the drain field, will need to be cleaned out on a regular basis by a contractor to maintain its effectiveness.
Solution for a clogged septic system
If your septic system becomes clogged and you find yourself having to clean the filter on a regular basis, you might be tempted to simply remove the filter altogether. Hold on to it. Solids, wastewater, and scum are separated into three levels in septic tanks, which allows them to function properly (see illustration above). Solids sink to the bottom of the container, where microbes breakdown them. The scum, which is made up of trash that is lighter than water, rises to the surface. In the drainage field, the middle layer of effluent leaves the tank and goes through an underground network of perforated pipes to the drainage field.
- Keep the effluent filter in place since it is required by your state’s health law.
- Waste particles might flow through the filter and clog the perforated pipes if the filter is not used.
- Your filter, on the other hand, should not require cleaning every six months.
- A good chance is high that you’re flushing filter-clogging things down the toilet, such as grease, fat, or food scraps.
- A garbage disposal will not be able to break down food particles sufficiently to allow them to flow through the septic tank filtration system.
- Plastic items, disposable diapers, paper towels, nonbiodegradable goods, and tobacco products will clog the system if they are flushed through it.
For additional information on what should and should not be flushed down the toilet, contact your local health authority. More information on removing lint from your laundry may be found here.
Get an inspection
Following a comprehensive first check performed by an expert, regular inspections will cost less than $100 each inspection for the next year. Your professional will be able to inform you how often you should get your system inspected as well as how a septic tank functions. As straightforward as a septic system appears, determining its overall condition necessitates the services of a professional. There are a plethora of contractors who would gladly pump the sludge out of your tank, but many, in my experience, are unable to explain how a septic system works or how it should be maintained.
A certification scheme for septic contractors has been established in certain states; check with your state’s Secretary of State’s office to see whether yours is one of them.
Also, a qualified inspector will be able to tell you whether or not your tank is large enough to accommodate your household’s needs, as well as the maximum amount of water that can be passed through it in a single day.
As you learn more about how a septic tank works, your professional should be able to tell you whether or not your system will benefit from this treatment.
Alternatives to a new drain field
If an examination or a sewage backup indicate that your drain field is in need of replacement, the only option is to replace it completely. As a result, it’s important to talk with a contractor about other possibilities before proceeding with the project.
- Pipes should be cleaned. A rotating pressure washer, used by a contractor, may be used to clean out the drain septic field pipes. The cost of “jetting” the pipes is generally around $200. Chemicals should be used to clean the system. A commercial solution (not a home-made one) that enhances the quantity of oxygen in the drain field should be discussed with your contractor before installing your new system. Septic-Scrub is a product that I suggest. A normal treatment will cost between $500 and $1,000. Make the soil more pliable. The practice of “terra-lifting,” which involves pumping high-pressure air into several spots surrounding the drain field, is authorized in some regions. Some contractors use it to shatter compacted dirt around the pipes. Depending on the circumstances, this might cost less than $1,000 or as much as $4,000 or more.
Protect your drain septic field from lint
When this device is in place, it inhibits lint from entering the system, especially synthetic fibers that bacteria are unable to digest. One of these filters, which I’ve designed and termed theSeptic Protector, was invented by me. An additional filter is included in the price of around $150 plus delivery. Learn more about how to filter out laundry lint in this article.
Don’t overload the septic system
Reduce the amount of water you use. The volume of water that flows into your tank, particularly over a short period of time, can be reduced to avoid untreated waste from being flushed into your drain field. Replace outdated toilets with low-flow ones, install low-flow showerheads, and, perhaps most importantly, wash laundry throughout the week rather than just on Saturday mornings to save water.

How a Septic System Works – and Common Problems
This Article Discusses Septic Tanks are a type of septic tank that is used to dispose of waste. Field Sizing and System MaintenanceProblems with the Leach FieldSystem Performance Questions and comments are welcome. See Also: Septic System Frequently Asked Questions Articles on SEPTIC SYSTEM may be found here. In locations where there are no municipal sewage systems, each residence is responsible for treating its own sewage on its own property, which is known as a “on-site sewage disposal system,” or septic system, more popularly.
One of the most commonly seen types of leach field is composed of a series of perforated distribution pipes, each of which is placed in a gravel-filled absorption trench.
It’s possible that a small number of homes will be sharing a bigger communal septic system that will function in a similar manner as a single-family system.
The wastewater is collected in the septic tank once it has been discharged from the residence. Septic tanks are normally between 1,000 and 2,000 gallons in capacity and are composed of concrete, strong plastic, or metal, depending on the model. Highly durable concrete tanks, which should endure for 40 years or more provided they are not damaged, are the most common. Many contemporary tanks are designed with two chambers in order to maximize efficiency. Household wastewater is collected in the septic tank, where it is separated and begins to degrade before being discharged into the leach field.
- In the tank, oil and grease float to the top of the tank, where they are known as scum, while solid waste falls to the bottom, where they are known as sludge.
- Bacteria and other microorganisms feed on the sediments at the bottom of the tank, causing them to decompose in an anaerobic (without oxygen) process that begins at the bottom of the tank.
- Solids and grease must be pushed out of the system on a regular basis in order for it to continue to function effectively.
- Each gallon added to the tank results in one gallon being discharged to the leach field, leach pit, or other similar treatment facility.
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.
More information on Septic System Maintenance may be found here.
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.
