What Soil Type Would Be Best For Drainage From A Septic Tank? (Solution found)

Soil Permeability Sandy soils feel gritty and can allow air and water to move rapidly through the soil. Clay soils are sticky and very dense, restricting the movement of air and water. The soils best suited for wastewater treatment are mixtures of sand, silt, and clays referred to as loamy soils.

  • Soil that is brightly colored is usually a lot better at providing drainage than soil that is dull and grey. Before installing a septic tank, a septic company will usually analyze the color of your soil to see how well it would potentially drain effluent and water. Soil Should Have Structure

What type of soil is best for treating effluent from a septic tank system?

In general, you want sandy soil that is not too coarse, well-drained soil, and naturally undisturbed soils to absorb the effluent. When the soil is too coarse, wastewater passes too quickly to receive sufficient treatment.

Is sandy soil good for septic?

Clay Soils cannot absorb sewage as rapidly as sandy or loamy soils and they become saturated more easily during winter months. Leachfields must be much larger in clay soils or they will become saturated, overloaded and fail. Sandy Soils absorb effluent more easily and are less prone to sewage failures.

What is septic soil?

Septic systems are underground wastewater treatment structures, commonly used in rural areas without centralized sewer systems. They use a combination of nature and proven technology to treat wastewater from household plumbing produced by bathrooms, kitchen drains, and laundry.

Is silt loam good for septic?

Silt loam and silty clay loam textures are very common in Illinois, having formed in loess parent material. When clay content in soils exceeds 35% (heavy cl, heavy sicl, sic, or c textures), the soils are generally poorly suited for conventional septic systems because of slow permeability.

What soil features may limit the use of a site for a septic tank drain field?

The limiting layer may be bedrock, an impervious soil layer or the seasonal high water table.

Will red clay soil perc?

Clay soils have notoriously slow percolation speeds of 0.1 inch or less per hour. These soils easily become waterlogged, and plant roots can suffocate as a result.

What soil is loamy?

What Is Loam? Loam is soil made with a balance of the three main types of soil: sand, silt, and clay soil. As a general rule, loam soil should consist of equal parts of all three soil types. This combination of soil types creates the perfect soil texture for plant growth.

How much soil should be on top of a septic tank?

the depth of soil backfill over the septic tank lid or septic tank riser lid, ranging from 0″ (which means you should see it) to just a few inches (which means grass may be dead in this area) to 6-12″ or even more.

How does soil affect septic tanks?

Soil-based systems discharge the liquid (known as effluent) from the septic tank into a maze of perforated pipes buried in a leach field that has been designed to slowly release the effluent into the soil or surface water. Without these organisms, your septic system might not work properly.

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?

What are the 3 types of septic systems?

Types of Septic Systems

  • Septic Tank.
  • Conventional System.
  • Chamber System.
  • Drip Distribution System.
  • Aerobic Treatment Unit.
  • Mound Systems.
  • Recirculating Sand Filter System.
  • Evapotranspiration System.

How deep should a septic drain field be?

A typical drainfield trench is 18 to 30 inches in depth, with a maximum soil cover over the disposal field of 36 inches.

What happens if my land doesn’t perk?

Without a successful perc test, there can be no septic permit. Without a septic permit, there can be no septic system. Without a septic system, there can be no dwelling of any kind. If the owner can’t build a dwelling of any kind, the property’s value will diminish substantially.

Can you have a septic tank without a leach field?

The waste from most septic tanks flows to a soakaway system or a drainage field. If your septic tank doesn’t have a drainage field or soakaway system, the waste water will instead flow through a sealed pipe and empty straight into a ditch or a local water course.

Best Soils for Septic Systems and Drain Fields – How to Choose the Right Soil

Best Soils for Septic Systems and Drain Fields

What do germs, dirt, and gravity all have in common? Read on to find out. All of these environmental elements and natural processes contribute to the ability of your septic system to perform its waste processing and wastewater treatment functions. Untreated water that is discharged back into the water table can pollute your town if these measures are not taken. While we understand how to maintain the health of the bacteria in our septic tanks, and while gravity works on its own, what about our soil?

Soil Requirements

Other rules, including as setbacks, tank capacity, and lawn size, are all important considerations. Soil requirements and soil types may make or break your septic system installation. Not only that, but there are a number of elements that must be considered when determining if the soil in your yard is suitable for a septic system and drainfield.

Structure

Natural processes such as wetting and drying, freezing and thawing, and freezing and thawing alter the soil structure throughout time. Pores and gaps are created in the various strata of the earth as a result of these activities. Pores allow for the free flow of water and air downward without being obstructed by other materials. Septic-system-ready soil should contain a significant number of pores and spaces that are linked, if at all possible (not lone pockets).

Texture

Are there any coarse or gritty soils present? Will the soils be able to absorb an excessive amount of water? Is it hefty or light in weight? The amount of sand, silt, and clay contained in the soil is determined by the texture of the soil. A high concentration of clay indicates that the soils are overly heavy. A ground that has too many heavy silts will be less permeable.

Drainage

In the absence of an exact definition or categorization, drainage refers to a soil’s natural capacity to drain water away from a specific location. For testing, check the soil moisture levels before doing any land alterations on a regular day (do not check the soil moisture levels the day after a hurricane or major storm passes by). Is there a quick and easy technique to categorize poorly draining soil? The soil in your yard is generally not the ideal for septic systems if there are regular depressions or puddling in your yard.

Slope

Slope angle is not directly connected to soil quality, but a steep slope will deny even the greatest soil the opportunity to percolate and treat wastewater before it enters the groundwater system.

How Do You Test Soil for Septic Systems?

Percolation tests, often known as deep hole tests, are performed. Deep Hole Tests are exactly what they sound like: tests that are conducted via a hole that has been drilled deeply. For the most part, the holes are around seven to ten feet deep and are located below the bottom of probable drainfield locations. Testers take soil samples and measure the height of the seasonal high water table in proportion to the depth of the soil above it, which they then analyze. Percolation testing necessitates the drilling of two or more holes, each of which is generally half a foot to a foot deep — the depth of an ordinary leach field — to determine the depth of the soil.

Even from one county to another and from one municipality to another, percolation needs differ. However, the lowest times per inch are often about 5 minutes, while the highest times per inch are typically over 30-45 minutes.

Best Soils for Septic Systems and Drainfields

Most yards and landscapes are composed of a variety of soil types, thus examining soil features and clay levels is more beneficial than identifying specific types of soil. The following are the ideal soils and soil types for drain fields:

  • Sandy soils
  • Soils with a low percentage of clay content
  • Loamy Soils (soils that include a variety of particle sizes that allow for gaps and pores to develop)
  • Soils that are either non-retentive or non-absorbent. Landscaping materials such as clay and silt rapidly absorb water, taking up additional area and clogging the system.

What is the optimal soil? Somewhere in the middle between gravel and clay.

What is the Best Soil for a Septic System?

When it comes time to break ground on your new property, if your home does not have access to a municipal sewer system, you’ll have to take care of the trash on your own, which is often accomplished through the installation of a septic system on your land. When installing a new septic system, homeowners must take a number of issues into consideration. Finding the greatest one that will work with your home is not as simple as browsing through a catalog and selecting the one that sounds the most appealing.

Do you think you understand what these elements are?

Contact us now to schedule a consultation.

To ensure that you are making the best selection possible when installing a new septic system, examine the following characteristics of your property.

Soil Texture

If your soil is dense and heavy, it is possible that you have an excessive amount of clay in your soil. While this may not appear to be a huge matter on the surface, it does make the region less porous, which can become an issue when exposed to a large amount of seepage. While having too much clay might be a problem, there has to be enough of it, as well as sand and silt, to ensure that it can absorb the water that is used by the household.

Sand vs. Clay

A thick and heavy soil might indicate that you have an excessive amount of clay in your soil. While this may not appear to be a huge matter on the surface, it does make the region less porous, which can become an issue when exposed to a large amount of seepage. There is a fine line between too much clay and too little clay, together with sand and silt, to ensure that the soil can absorb the water that is used by the house.

Check the Drainage Capabilities of Your Soil

As previously said, water must drain once it has exited your septic tank, thus soil that drains and percolates is an absolute essential. In the event that you are experiencing water build-ups in your backyard and the formation of numerous puddles after rainstorms, this is a clear indication that your soil is not going to cooperate with the installation of a new septic system. There are a variety of reasons why your soil isn’t draining properly, all of which can have a negative impact on a perc test.

It is possible that your soil failed the perc test due to an unchangeable cause. If you are not sure what happened, test your soil on a dry day and then examine what happens to your soil when it is exposed to water.

Perc Testing

The pace at which water drains through soil is determined using perc testing. When establishing a septic system, you want soil that is capable of handling the drainage requirements of the new system you are installing. Because of inadequate drainage, the likelihood of wastewater accumulating on the surface and forming big puddles in your lawn increases by orders of magnitude every year. When considering the installation of a new septic system on your property, it is required by Pennsylvania State Law that a percolation test be conducted first.

After that, a flotation device is lowered into the water.

What is the Best Soil Type for Septic Systems?

However, while a combination of gravel and clay is the most optimal for septic systems, other qualities may be used to do the job just as well. Soils containing sand, as well as loamy soils, fall under this category. Loamy soils are made up of a combination of sand, silt, and clay, and they provide a unique combination of permeability and absorption rates that are ideal for septic tank construction. In either case, be certain that you take the necessary procedures to ensure that your soil will sustain a new septic system if you decide to pursue this option.

Soils types and their impact on septic systems

Even if your septic system is in excellent condition, it is dependent on the correct type of soil to finish the process of purifying the wastewater from your home. Depending on the soil type in the drainfield region, how well the effluent is filtered and whether or not the water that is returned to the water cycle is good enough will be determined. As a result, while installing a septic system, it is critical to have a thorough grasp of the soil makeup. Soil is composed of a variety of layers that are divided into four major categories: surface soil, subsurface soil, subsoil, and substratum.

See also:  Why Can I Use Bleach With A Septic Tank? (Solved)

Surface soil– also known as topsoil, this type of soil is generally black in color due to the high concentration of organic materials present due to the decaying organisms.

Typically, this is where the drain field is located.

Subsoil is the layer of soil that lies beneath the subsurface soil and is composed of a mixture of small particles of clay, silt, and sand, but it contains less organic matter than the surface soil.

Subsurface soil is composed of small particles of clay, silt, and sand, but it contains more organic matter than the surface soil. Due to its composition of either unconsolidated sediment or bedrock, the substratum is sometimes referred to as a non-soil layer.

Morphological characteristics of soil

The morphology of the soil dictates the type of septic system that will be implemented as well as the effectiveness of the system after it is established. When planning a septic system, there are five crucial soil morphological aspects that must be taken into consideration. These are the ones:

Soil texture

The relative proportions of the various soil particles in the soil are referred to as the texture of the soil. The texture of the soil can have a negative impact on a soil’s capacity to process and safely dispose of wastewater, according to the Environmental Protection Agency. The porosity, hydraulic conductivity, and structure of the soil are all influenced by the texture of the soil. Soils with a heavy texture, such as clay soils, have poor drainage characteristics. As a result, water does not pass through them quickly enough to dispose of the necessary amount of wastewater.

When it comes to septic system design, soils are divided into four major groups based on the texture of the soil.

  • Sandy textured soils are classified into four groups: Group I
  • Group II
  • Coarse Loamy Textured Soils
  • Group III
  • Fine Loamy Textured Soils
  • And Group IV
  • Clayey Textured Soils.

Soils in Group I and Group II are the most suitable for use with traditional septic systems. Group III and Group IV soil textures may need the construction of more sophisticated sewage treatment systems.

Soil structure

Soil structure is concerned with how individual soil particles are grouped together to produce bigger groupings of particles, which are referred to as aggregates in the scientific community. As a result of its structure, soil has an influence on water percolation, the capacity of soil to handle wastewater, and the quantity of air that may be introduced into the soil. There are five distinct approaches to characterize soil structure, which are as follows:

  • Absence of structure (e.g. single grain or massive)
  • Crumb and granular
  • Block-like
  • Platy
  • Prismatic
  • Absence of structure (e.g. single grain or massive)

Septic systems benefit from granular soil structure because it increases soil separation and internal drainage, which is perfect for septic systems. On the other hand, soil types with a platy, prismatic, or massive structure are not recommended for use with traditional septic systems. The huge and platy structures hinder aeration as well as internal drainage, whereas prismatic structures allow untreated wastewater to flow directly into the water table without being treated first.

Clay mineralogy

Clay mineralogy is concerned with the quantity of clay present in a soil, and this will have an impact on the percolation rate of the soil as a result. Generally speaking, there are two sorts of clays: 2:1 and 1:1. A 2:1 clay is one that expands significantly when wet, whereas a 1:1 clay just barely expands when wet. Clays with a 2:1 mineralogy (for example, montmorillonite) shrink when they are dry and expand when they are wet, as seen in the diagram. As the soil swells, the particles of the soil expand into the structural spaces, reducing the porosity of the soil in the process.

Consequently, soils with a 2:1 clay mineralogy are ineligible for the installation of traditional septic tanks.

That a result, they do not limit the flow of water to the same extent as their 2:1 counterparts do. They are capable of assisting with the installation of septic systems.

Soil consistency

The consistency of a soil is assessed by testing how well a certain soil can adhere to other things or how well it can form forms when pressed between two surfaces. When the soil is dry, damp, or even wet, it is possible to identify the consistency of the soil. Firmness, friability, and looseness are the characteristics that influence the consistency of most soils. It is possible that the soil may be particularly solid when wet, indicating that it contains expansive mineralogy, and it will be rated as unsuitable for septic systems.

It is possible to determine how effectively dirt adheres to other things by pushing the soil between two fingers: the thumb and forefinger.

To determine the flexibility of the soil, roll a small amount of it between your thumb and forefinger.

Organic soils

Organic soils are defined as soils that contain 20 percent or more organic matter to a depth of at least 18 inches and are rich in organic matter. If your soil falls within this category, you should avoid installing septic systems. Organic soils, on the other hand, tend to remain moist throughout the year because they drain too slowly. Organic soils are particularly susceptible to subsidence, which can cause damage to the septic system.

Soil wetness

Wastewater treatment cannot take place adequately in soils that are not sufficiently aerated. As soon as soils become saturated with water, the spaces are filled with water, leaving little or no space for air to circulate. Because moist soils lack adequate air circulation, they are unable to maintain a septic system. The color of the soil may be used to determine the amount of moisture in the soil. The term “chroma” refers to the relative purity, strength, and saturation of a soil’s color in terms of its color.

For example, moist soils have a chroma value of two.

When the water table is high during a certain season, the soil may become wetter than usual at regular times.

Constituents of wastewater and how they react with various soil types

Various elements of wastewater can have varied effects on the soil depending on their concentration. Check out the following examples of wastewater ingredients to see how they could react in different soils.

Organic substances

BOD (Biological Oxygen Demand), Total Suspended Solids (TSS), and Chemical Oxygen Demand (COD) are all metrics used to assess the concentrations of synthetic and natural organic chemicals in wastewater (COD). Ideal conditions exist when a well designed and maintained septic system can remove the majority of these components through the liquefaction process initiated by the bacteria. The leach field, on the other hand, continues to receive certain organic compounds that have gone through the septic tank.

Organic compounds are removed from the soil via a variety of processes, including filtering and decomposition, that occur naturally.

The bacteria in the effluent store polysaccharides in the form of slime capsules, which coat the soil particles and reduce the soil’s ability to percolate water through the soil.

When building a septic system, it is important to consider adequate size in order to avoid an excess of effluent in the leach field, which might worsen the biomat problem.

Nitrogen

Ammonia, ammonium, ammonium nitrate, nitrite, and organic nitrogen are all found in the effluent from septic tanks, as is nitrate and nitrite. Anaerobic bacteria produce these as by-products of the sewage treatment process, which is why they are called anaerobic bacteria. Even effluent from aerobic tanks, on the other hand, contains nitrogen in the form of nitrate. Nitrogen removal through sludge accounts for around 10% of total nitrogen removal; the remainder is removed by the soil through processes such as denitrification, volatilization, plant uptake, and adsorption, among others.

In aerobic circumstances, nitrate is mostly soluble and does not interact with the soil components in a positive manner.

Phosphorus

When it comes to phosphorus in septic tank effluent, there are two primary sources: washing detergents and human feces. Fortunately, anaerobic bacteria are capable of turning the majority of this phosphorus into soluble orthophosphates. To the contrary of nitrogen compounds, soluble phosphates react with diverse soil types and result in the removal of phosphate ions through numerous processes such as soil-plant interaction, plant uptake, precipitation, and biological immobilization (bio-immobilization).

Détergent surfactants

Surfactants, in general, can have an impact on the water retention and water transportation characteristics of soil. When the surfactant concentrations in the septic system exceed 30 mg/l, they have the potential to limit the hydraulic conductivity of the soil, which means that the wastewater will not be able to pass freely through the soil. The overall consequence will be that the water levels in the septic tank will increase over what is considered to be optimal. As a result of adsorption, anionic surfactants begin to build in the soil as detergent surfactants are removed from the environment.

This may be accomplished with relative ease by refraining from the use of detergents that include surfactants.

Toxic organic compounds

Toxic organic substances like as trichloroethylene (TCE), chlorinated hydrocarbons (MC), methyl chloroform, and others are widely found in chemical septic additives and cleansers. Trichloroethylene (TCE), chlorinated hydrocarbons (MC), methyl chloroform, and others are toxic organic compounds. If they reach the saturated zone, MC and TCE will sink to the bottom of the water phase, since they are denser than water and will sink to the bottom of the water phase. Several of these organic molecules remain in the sludge as a result of their inability to decompose, while others end up in the drain field and end up poisoning groundwater.

As a result, owners of septic systems should avoid the use of these compounds altogether. Biological additives, such as those manufactured from bacteria and enzymes and sold by Bio-Sol, are recommended for cleaning septic systems.

Bacteria

As single-celled creatures, bacteria are frequently found stuck in the pore spaces of soil particles, where they can cause significant damage. This is, in fact, an essential process since it aids in the removal of enteric bacteria from the effluent in the leach field, which is beneficial for the environment. This process also leads in the development of biomat, which aids in the entrapment of bacteria in the system. The attenuation of bacteria contributes to the prevention of groundwater contamination with disease-causing germs.

Furthermore, the attenuation of bacteria is controlled by the amount of bacteria present in the effluent, soil texture, loading rate, kind of bacteria present, soil moisture, and temperature.

Viruses

Viruses are not only smaller in size than bacteria, but they also function in a distinct manner in the environment. Natural die-off and enzyme assault are among the methods used to inactivate or remove viruses from the soil. Precipitation, adsorption, filtration, and natural die-off are among those employed. In fact, many of the same variables that influence the adsorption of bacteria by soil also influence the adsorption of viruses by the soil. There are several critical soil factors that influence viral adsorption.

How the soil type and its percolation impacts the performance of the septic system

The behavior of effluent is influenced not only by the element in question, but also by the state and composition of the soil underneath it. The degree of wetness is governed by a number of factors, one of which is the distance between the surface and the water table. Depending on rainfall patterns and human activities such as irrigation and stormwater management, the depth of the water table can change significantly. When building a septic system, it is critical to consider how much vertical separation there should be between the water table and the bottom of the drain field.

  1. It is more difficult for water to move through unsaturated soil than it is for water to go through more saturated soil in the same area.
  2. When building a septic system, it is vital to consider the depth of the water table during the rainy season, which is measured in feet.
  3. When the wet season arrives, soils with impermeable horizons are more likely to create perched water levels.
  4. In the course of the site research, it is critical to take note of several significant soil features such as the texture of the soil, the presence or absence of cemented layers, the degree of aggregation of soil particles, and the level of the water table during the rainy seasons.
  5. For example, it may be necessary to create alternative systems such as mounds in order to increase the distance between the rainy season water table and the bottom of the system during the dry season.

The same procedure may be required in the case of cemented soil, clay soil, or in the case of any other unacceptable conditions that may be discovered during the site assessment.

Conclusion

There are some soils that are not suited for typical septic systems, and installing septic systems on these soils without taking the proper precautions can result in a variety of problems, including water pollution. Clay soil is extremely compact and does not allow for the passage of wastewater through it to occur. As a result, clay soils have the potential to cause blockages in the leach field. The optimal soil for a septic system is one that is somewhere in the middle of the spectrum between gravel and clay.

This soil offers the ideal characteristics for filtering wastewater while yet enabling it to soak through and into the surrounding environment.

Good and Bad Soils for the Septic System – Septic Maxx

Some soils are not the most suitable for typical septic systems, and installing septic systems on them without taking the appropriate precautions can result in a variety of problems, including water pollution and groundwater contamination. It is impossible for wastewater to soak through clay soil because it is so compacted. A backlog in the leach field is consequently possible when clay soils are present. For a septic system, the optimal soil is one that is halfway between gravel and clay in texture.

This soil offers the ideal characteristics for filtering wastewater while yet enabling it to soak through and into the groundwater below the surface.

What’s in Soil?

Any randomly selected sample of soil will disclose the fundamental disintegration. It is made of 50% solid material and 50% pore space, which is the composition of soil. Organic plant materials, as well as three different mineral kinds (sand, clay, and silt) can be found inside the solid mass. Within the pore space, you will discover a space that is 25 percent filled with water and 25 percent with air (25 percent ). The texture of the soil is the factor that has the most influence on its ability to filter wastewater effectively.

Sand particles are the largest of all the particles since they are visible to the human eye and have a gritty feel, making them the most noticeable.

Clay particles are the tiniest, measuring only 0.002 mm in diameter, and they become sticky when wet.

Is My Soil Good or Bad?

Without the assistance of an expert, determining good drainfield soil may be challenging. During a soil evaluation, it is necessary to examine a variety of soil parameters, including texture, structure, density, and color. For effluent absorption, you want sandy soil that is not too coarse, well-drained soil, and naturally undisturbed soils, all of which are found in natural settings. In cases when the soil is too coarse, wastewater runs through it too rapidly for it to obtain adequate treatment.

Clay particles can also expand and obstruct soil passageways, further delaying the transport of wastewater through the system.

Hardpan is the term used to describe this ailment.

Soils and Septic Systems

What types of soils are suitable for use with septic tanks? Septic systems are available in a variety of shapes and sizes, but they always have one characteristic. They are all dependent on the soil in which they are put. If you spend much time with septic professionals, as I do, you will frequently hear them repeat the slogan “The soil is the system.” An absorption field is included in every septic system. If the soil does not comply, no matter how vast, elaborate, or expensive the septic system is, it will not function properly.

  • High clay concentration (the more the amount of clay present, the slower the absorption rate)
  • Till that is densely compacted, hardpan, and bedrock (all of which limit water flow)
  • High seasonal water table with shallow water table (which is not suited for absorption systems)
  • Loading rates in soils with high organic content (i.e. muck) are extremely low and variable
  • Soils that are coarse and gravelly (because they drain too quickly to allow for appropriate treatment of the effluent)
  • Soils that have been manhandled and moved around have lost their natural structure and drainage capabilities
  • Fill and/or compacted soils

Very tiny particles make up clay soils, which is why they are so dense. In order to avoid flooding, the water drains slowly through this deep soil. The reason for this is because absorption systems in clay soils are far bigger (and more expensive) than absorption fields in sandier soils. Clay soils, on the other hand, prefer to retain water rather than release it, owing to their capillary action. Let us now take a look at the soil texture! There are three distinct sized soil particles known as sand, silt, and clay that make up all of the soil.

  • The clay at the very top of the triangle is 100 percent pure.
  • All soils have a combination of sand, silt, and clay and are classified according to their texture class within the triangle.
  • Please keep in mind that the textures provided in the soil report will be shortened (for example, Sandy Load = SL, Loam = L, Sand Clay Loam = SCL, and so on).
  • What factors do soil scientists consider when determining texture?
  • Silty soil has a slick texture to it (like wet flour).
  • The texture of the soil is also essential.
  • The poorer the soil’s structural integrity, the less compatible the soil is with drainage and septic system design and installation (especially in heavy soils).

The dirt is regarded as “huge” since it lacks any structure.

For this reason, the roots of plants don’t bother entering this soil because there is no water present in the soil.

As previously said, thick soil has a natural affinity for holding water, much like a sponge (actually, even more than a sponge).

If the soil is saturated with water, the septic effluent will not be effectively treated before it enters the groundwater supply system.

To put it another way.

In some seasons of the year, water may be present, while in others, it may not.

Well-drained soils, on the other hand, are the polar opposite.

What is the best way to drain my soggy soil?

Perimeter drains, curtain drains, and interceptor drains are all terms used to describe these types of drains.

If you want to guarantee that your interceptors (or perimeter drains) are functional, they must be put much below the depth of your trenches.

Which Soils Are Best for Septic Tanks?

You should take into consideration several different variables when you are installing an exterior septic system in order to make the septic system as effective and efficient as it possibly can be. One of these considerations is the soil that surrounds the septic system itself. It is possible that your septic system will not function properly because you have the improper sort of soil in your yard. Some forms of soil are substantially better at treating and filtering sewage from septic systems than other types of soil, and some of these types are listed below.

Soil Shouldn’t be Too Dense

The soil that is utilized to construct a septic system’s drain field, as well as the soil that surrounds that drain field, must be capable of dispersing the effluent that is generated inside the system. If the soil is too thick, the effluent will not be able to move through it quickly, and hence will not be able to dissipate as effectively. It has the potential to cause drainage problems in the future. On the other hand, soil should not be excessively loose, as this might result in effluent running through it too rapidly, poisoning nearby water sources.

Soil Shouldn’t Have a Dull or Grey Color to It

Both the soil used to construct a septic system’s drain field and the soil that surrounds that drain field must have the ability to disperse the effluent that is generated within the system as a result of its operation. If the soil is too thick, the effluent will not be able to move through it quickly, and so will not be able to dissipate as effectively as it should. In the long run, it may cause drainage problems. The soil should not be too loose, on the other hand, because this might result in effluent running through it too fast and damaging nearby water supplies.

Soil Should Have Structure

Most of the time, if you look closely at the dirt in a yard, you will see that it has a distinct structure to it. A ped is formed when soils of similar sorts gather together to produce a compacted mass of dirt. A ped occurs naturally and is a mixture of particles that can aid in the transportation of water and sewage underground by promoting the movement of these substances. Soil that retains this form of structure is typically preferable for septic systems over soil that does not retain any structure at all.

Types of Septic Systems

Septic system design and size can differ significantly from one neighborhood to the next, as well as throughout the country, due to a variety of variables. Household size, soil type, slope of the site, lot size, closeness to sensitive water bodies, weather conditions, and even municipal ordinances are all considerations to take into consideration.

The following are 10 of the most often encountered septic system configurations. It should be noted that this is not an exhaustive list; there are several additional types of septic systems.

  • Septic Tank, Conventional System, Chamber System, Drip Distribution System, Aerobic Treatment Unit, Mound Systems, Recirculating Sand Filter System, Evapotranspiration System, Constructed Wetland System, Cluster / Community System, etc.

Septic Tank

This tank is underground and waterproof, and it was designed and built specifically for receiving and partially treating raw home sanitary wastewater. Generally speaking, heavy materials settle at or near the bottom of the tank, whereas greases and lighter solids float to the surface. The sediments are retained in the tank, while the wastewater is sent to the drainfield for further treatment and dispersion once it has been treated.

Conventional System

Septic tanks and trench or bed subsurface wastewater infiltration systems are two types of decentralized wastewater treatment systems (drainfield). When it comes to single-family homes and small businesses, a traditional septic system is the most common type of system. For decades, people have used a gravel/stone drainfield as a method of water drainage. The term is derived from the process of constructing the drainfield. A short underground trench made of stone or gravel collects wastewater from the septic tank in this configuration, which is commonly used.

Effluent filters through the stone and is further cleaned by microorganisms once it reaches the soil below the gravel/stone trench, which is located below the trench.

Chamber System

Gravelless drainfields have been regularly utilized in various states for more than 30 years and have evolved into a standard technology that has mostly replaced gravel systems. Various configurations are possible, including open-bottom chambers, pipe that has been clothed, and synthetic materials such as expanded polystyrene media. Gravelless systems can be constructed entirely of recycled materials, resulting in considerable reductions in carbon dioxide emissions during their lifetime. The chamber system is a type of gravelless system that can be used as an example.

  • The key advantage of the chamber system is the enhanced simplicity with which it can be delivered and built.
  • This sort of system is made up of a number of chambers that are connected to one another.
  • Wastewater is transported from the septic tank to the chambers through pipes.
  • The wastewater is treated by microbes that live on or near the soil.

Drip Distribution System

An effluent dispersal system such as the drip distribution system may be employed in a variety of drainfield configurations and is very versatile. In comparison to other distribution systems, the drip distribution system does not require a vast mound of dirt because the drip laterals are only placed into the top 6 to 12 inches of soil. In addition to requiring a big dosage tank after the sewage treatment plant to handle scheduled dose delivery of wastewater to drip absorption areas, the drip distribution system has one major disadvantage: it is more expensive.

This method necessitates the use of additional components, such as electrical power, which results in a rise in costs as well as higher maintenance.

Aerobic Treatment Unit

Aerobic Treatment Units (ATUs) are small-scale wastewater treatment facilities that employ many of the same procedures as a municipal sewage plant. An aerobic system adds oxygen to the treatment tank using a pump. When there is an increase in oxygen in the system, there is an increase in natural bacterial activity, which then offers extra treatment for nutrients in the effluent. It is possible that certain aerobic systems may additionally include a pretreatment tank as well as a final treatment tank that will include disinfection in order to further lower pathogen levels.

ATUs should be maintained on a regular basis during their service life.

Mound Systems

Using mound systems in regions with short soil depth, high groundwater levels, or shallow bedrock might be a good alternative. A drainfield trench has been dug through the sand mound that was erected. The effluent from the septic tank runs into a pump chamber, where it is pumped to the mound in the amounts recommended. During its release to the trench, the effluent filters through the sand and is dispersed into the native soil, where it continues to be treated. However, while mound systems can be an effective solution for some soil conditions, they demand a significant amount of land and require regular care.

Recirculating Sand Filter System

Sand filter systems can be built either above or below ground, depending on the use. The effluent is discharged from the septic tank into a pump compartment. Afterwards, it is pushed into the sand filter. The sand filter is often made of PVC or a concrete box that is filled with a sand-like substance. The effluent is pushed through the pipes at the top of the filter under low pressure to the drain. As the effluent exits the pipelines, it is treated as it passes through the sand filtering system.

However, sand filters are more costly than a standard septic system because they provide a higher level of nutrient treatment and are thus better suited for areas with high water tables or that are adjacent to bodies of water.

Evapotranspiration System

Evaporative cooling systems feature drainfields that are one-of-a-kind. It is necessary to line the drainfield at the base of the evapotranspiration system with a waterproof material. Following the entry of the effluent into the drainfield, it evaporates into the atmosphere. At the same time, the sewage never filters into the soil and never enters groundwater, unlike other septic system designs. It is only in particular climatic circumstances that evapotranspiration systems are effective.

The environment must be desert, with plenty of heat and sunshine, and no precipitation. These systems perform effectively in shallow soil; but, if it rains or snows excessively, they are at risk of failing completely.

Constructed Wetland System

Construction of a manufactured wetland is intended to simulate the treatment processes that occur in natural wetland areas. Wastewater goes from the septic tank and into the wetland cell, where it is treated. Afterwards, the wastewater goes into the media, where it is cleaned by microorganisms, plants, and other media that eliminate pathogens and nutrients. Typically, a wetland cell is constructed with an impermeable liner, gravel and sand fill, and the necessary wetland plants, all of which must be capable of withstanding the constant saturation of the surrounding environment.

As wastewater travels through the wetland, it may escape the wetland and flow onto a drainfield, where it will undergo more wastewater treatment before being absorbed into the soil by bacteria.

Cluster / Community System

In certain cases, a decentralized wastewater treatment system is owned by a group of people and is responsible for collecting wastewater from two or more residences or buildings and transporting it to a treatment and dispersal system placed on a suitable location near the dwellings or buildings. Cluster systems are widespread in settings like rural subdivisions, where they may be found in large numbers.

What Are The Best Soil Types for Your Septic System? – A A Septic Tank & Drain Service

While you have probably given much attention to which septic system is most appropriate for your property, you may not have considered which environment is most appropriate for your septic system. One of the most crucial aspects of a healthy system is having the right soil in place, because that soil is responsible for creating the drain field, which is the region where waste products are discharged and cleaned in the earth. Here’s a guide to frequently asked questions concerning soils for septic systems, as well as answers to those topics.

FAQs About Septic System Soil

While you have probably given much attention to which septic system is most appropriate for your property, you may not have considered which environment is most appropriate for your septic system to operate in. In order for a system to thrive, the soil must be of high quality, since this soil is responsible for creating the drain field, which is the region where waste products are discharged and cleaned in the earth. Listed below is a FAQ section that addresses the most commonly asked issues concerning soils for septic system installations.

Should my soil be porous?

Porosity of the soil is essential if you plan to establish a septic system on your property. The presence of certain holes in the earth allows for the passage of air and water, which aids in the smooth operation of the detoxification process. It is possible that your soil is too dense, in which case there will be no flow of air or water, and your system will not function.

Is easy drainage a necessity?

A certain amount of water is necessary for healthy soil and for your drain field to work effectively; however, too much water might drown out the waste liquid in your drain field.

This will drive it into the waste table, where it will remain until it has completed its detoxification. As a result, having soil that drains efficiently is quite beneficial.

So, what soil type fits the bill?

You should look for soils with a high loam component since they have a permeable structure and are thus better for gardening. You should also avoid using absorbent soils such as clay and silt, which absorb water and cause the drain field to overflow. Sandy soil is also a good choice since the bigger grains assist to absorb the effluent, as opposed to smaller particles such as those found in clay, which enable the effluent to flow through and into the environment.

What is the best septic system for clay soils?

According to the diagram below, a septic system separates waste into three levels, with one layer being treated and exiting the tank, and another layer being discarded. With the outlet pipe, the water drains away to a soakaway or drainage field, while the remaining contents of the tanks remain in the tanks as’sludge’ until they are regularly emptied, which is known as desludging. Clay soils may be problematic for septic systems since it is not the most effective soil for absorbing and purifying water, as it is in other soil types.

How do you know if you have clay soil?

Ask yourself how your soil seems when it is hot or rainy, and you will have the answer. If your garden becomes flooded for an extended period of time following heavy rains, you may have clay soil. If your garden gets exceedingly hard and very dry after a hot time, this might also indicate that you have clay soil in your garden. The most effective course of action is to do an apercolation test. If you’re quite certain that you have clay soil, a percolation test will prove that you do indeed have clay.

What’s the problem with clay soil and septic tanks?

One-third of the contents of an aseptic tank is drained away into a soakaway or a drainage field. This is done in order for the water to flow through this system and be partially cleansed by the soil because it passes through small holes in the soil, leaving any debris or undesired things in the ground as it goes through the system. It is impossible for water to travel through clay soil because there aren’t large enough spaces between the particles in the soil (hence the dry baked ground in hot weather, and water-logged garden during rainy spells).

Despite the fact that the water is being pumped out of the septic tank, it is unable to escape, resulting in unclean untreated water accumulating in a sodden path surrounding the tank. As the water strains to exit the system, the septic tank is more than likely to back up as a result.

What are the alternatives to clay soil septic tanks? What’s the best septic system for clay soils?

Soakaway systems do not work well on clay soils, therefore stay away from any septic system or sewage treatment facility that makes use of them. The installation of a sewage treatment plant is recommended in the event that your septic tank is located adjacent to a watercourse such as a lake, river, stream, canal, or other similar body of water. High-level sewage treatment facilities generate water of a quality that is clean enough to be injected directly into a water course. It’s important to double-check with the Environmental Agency to ensure that this is OK; you don’t want to be penalized if your watercourse is a rare exception to this rule.

You may just discharge the water into this if you have a large amount of land (which is frequent around off-mains properties).

Septic tank in clay soil? Here’s what you need to know

Septic tanks do not provide much in the way of treatment for the waste generated by the toilets and sinks on your home. Really, all they do is separate the garbage that goes into the bins into three layers (it’s not worth thinking about what that may look like while you’re having your lunch, just trust me on this). The middle layer of separated waste water is what exits the tank; the rest is maintained within the tank and it is this that is removed during your routine septic tank emptying procedure.

A soakaway system or drainage field

Septic tanks are not particularly effective at treating the waste generated by the toilets and sinks on your house. To be honest, they just provide a three-layer separation of the garbage that enters the facility (it’s best not to think about what that may look like while you’re having your lunch). The middle layer of separated waste water is what exits the tank; the remainder is maintained within the tank and it is this that is removed during your routine septic tank emptying. Water from the tank exits through an outflow pipe and is sent to one of the following destinations:

A sealed pipe which runs straight to a local watercourse or a ditch

Please be advised that, as of January 1, 2020, you will no longer be permitted to have waste water from a septic tank discharged directly into a river or ditch without prior approval. Detailed information regarding the legislative change and what it implications may be found in our Guide.

There has been a shift in thinking since it is no longer believed that waste water is clean enough to be discharged directly into waterways without first being treated (as it would be if it passed through a soakaway system).

So why is it relevant if you have a septic tank in clay soil?

We would like to remind you that starting on January 1, 2020, you will no longer be permitted to have waste water from your septic tank discharged directly into a watercourse or ditch. Detailed information on the legislative change and what it entails may be found in our Guide to the New Laws. There has been a shift in policy since it is no longer believed that waste water is clean enough to be discharged directly into waterways without first being cleaned (as it would be if it passed through a soakaway system).

What are your options if you have a septic tank in clay soil?

The installation of a soakaway system or drainage field on your land will be ineffective unless you have another location within your property’s boundaries that does not contain clay soil. Through the use of an apercolation test, it is possible to assess the type of soil and how porous it would be. For those who aren’t sure where to begin, this is an excellent place to start because it will tell you whether any part of the land on your property is appropriate – and if so, what size and kind of soakaway system may be required.

A sewage treatment plant generates waste water of higher quality, allowing you to have greater flexibility in deciding where the waste water from the plant should be discharged.

On conclusion, installing a septic tank in clay soil might be difficult, but there are several choices available.
