How To Determine Type Of Septic Tank? (Solution found)

  • The location and soil conditions of the home or business property will generally determine the type of septic tank system that is required for installation. Conventional Systems can either be Gravity System which is the basic or standard system, or Pressure Distribution System.

How can I tell what type of septic system I have?

Walk around your yard to look for a large bump in the grass on one side of the house. A sign that you have a septic system is a domed area under the grass. The size of the bump will vary depending on your house and the number of toilets you have, but it may be noticeable.

What are the different types of septic tanks?

Septic Tank Types

  • Concrete. Concrete septic tanks. These durable tanks will usually last for several decades.
  • Steel. Steel septic tanks.
  • Fiberglass. Fiberglass septic tanks.
  • Plastic. Plastic septic tanks.
  • Aerobic. Aerobic septic tanks.

What are the 2 types of septic systems?

There are two basic septic system types — conventional and alternative. Site and soil conditions generally determine the type of system that should be installed.

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.

How do I calculate the size of my septic drain field?

Drainfield Size

  1. The size of the drainfield is based on the number of bedrooms and soil characteristics, and is given as square feet.
  2. For example, the minimum required for a three bedroom house with a mid range percolation rate of 25 minutes per inch is 750 square feet.

What is the difference between a septic tank and a septic field?

The septic tank is a buried, water-tight container usually made of concrete, fiberglass, or polyethylene. The liquid wastewater (effluent) then exits the tank into the drainfield. The drainfield is a shallow, covered, excavation made in unsaturated soil.

What is a Class 5 septic system?

Class 5. A sewage system using a holding tank for the retention of on-site sewage and must be emptied by a licensed sewage hauler. A permit is required to install this type of septic system.

Which type of septic tank is best?

The best choice is a precast concrete septic tank. Precast septic tanks hold many advantages over plastic, steel, or fiberglass tanks. This is why so many cities and towns actually require the use of concrete septic tanks.

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?

Does shower water go into septic tank?

From your house to the tank: Most, but not all, septic systems operate via gravity to the septic tank. Each time a toilet is flushed, water is turned on or you take a shower, the water and waste flows via gravity through the plumbing system in your house and ends up in the septic tank.

What is the difference between aerobic and anaerobic septic systems?

The basic difference between aerobic and anaerobic septic systems is the presence or absence of oxygen. Traditional anaerobic septic systems operate in underground tanks and in the relative absence of oxygen. Aerobic septic systems are thus able to support aerobic forms of bacteria.

What is the average cost of an aerobic septic system?

An aerobic septic system has an average cost between $10,000 and $20,000. You need to have the system professionally inspected and pumped every one to three years, which has an average cost of $200. 6

How often do aerobic septic systems need to be pumped?

How Often Should My Aerobic System Be Pumped? There are many variables that affect how often your system needs to be pumped. This is determined by the usage of your system, and the number of people living in your home, we suggest that your system be pumped every three to five years.

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.

  • A variety of reasons might cause septic system design and size to differ significantly from one location to another, both inside and outside of your community. Household size, soil type, slope of the site, lot size, proximity to sensitive water bodies, weather conditions, and even municipal ordinances are all aspects to consider when making a home purchase. Septic systems come in a variety of shapes and sizes, and the following are the 10 most popular. There are a variety of additional types of septic systems not included in this list.

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 comes into touch with the earth when it is contained within the chambers. 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.

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.

Constructed Wetland System

Drainfields are peculiar to evapotranspiration systems. An impervious substance is used to line the base of the evapotranspiration system drainfield. Following the entry of the effluent into the drainfield, it evaporates into the surrounding air (see Figure 1). Unlike other types of septic systems, the effluent never filters into the soil and never reaches groundwater. It is only in particular climatic circumstances that evapotranspiration systems are useful. There must be enough of heat and sunlight in the environment, as well as no rain.

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.

Identify My Septic System

It is a decentralized wastewater treatment system that is under some sort of community ownership that gathers wastewater from two or more residential or commercial buildings and transports it to a treatment and dispersal system that is placed on a suitable site near the residences or buildings. Cluster systems are widespread in settings such as rural subdivisions, where they may be found in large numbers.

Conventional Systems

Traditional septic systems may be divided into two categories: those that employ gravel in the drain field and those that use some sort of chamber system. The older style graveled system, as the name implies, has a coating of gravel in the drain field to facilitate drainage. In the course of the building, a drain field ditch is dug that is 1 to 3 feet below ground level. Its length is decided by the amount of wastewater that will be discharged into the system from the house or rural office, as well as the soil’s ability to absorb water during the winter months.

  1. In order to prevent backfill soil from filtering between the rocks and reducing the field’s ability to absorb water, additional gravel is poured around and over the pipe.
  2. Despite the fact that some waste is treated in septic tanks by bacteria that live within the tank, the majority of waste is treated when wastewater released from the tank enters the drain field and is filtered via the gravel and dirt under the surface.
  3. These organisms grow and produce a layer known as a biomat, which sits on top of the soil layer and protects it.
  4. When the drain field is in balance, these organisms prevent the biomat from getting so thick that it prevents wastewater from passing through to the soil underneath the drain field.
  5. In the first place, the use of gravel instantly reduces the amount of wastewater that may reach the soil, which is where the majority of filtration takes place.
  6. Apart from that, even when competent contractors utilize solely cleaned gravel, a certain quantity of particles is certain to stay and eventually reach the soil level, further lowering the possibility of filtering.
  7. This can happen when the water table rises above the drain pipe, essentially cutting off the drain field’s capacity to release water and causing it to back up.

In addition, when there are more visitors in the house for extended periods of time, or when taps or toilets are left running for extended periods of time, there is the chance of a drain field overflow, which can develop.

Gravel-less conventional systems have the advantage of overcoming some of the disadvantages of graveled systems.

Typically, these chambers are made of molded high-density plastic and are available in lengths ranging from 4 to 5 feet.

When the system is put into service, waste water is transported via pipe from the septic tank to the chamber run, where it flows directly against the earth.

One significant advantage of the chambered system is its capacity to accommodate significantly greater volumes of water.

Shock loading over extended periods of time will, without a doubt, have a negative impact on the biomat since oxygen will not be accessible to parasites during these durations.

Low-Pressure Dose Systems

Low-pressure dosing systems (also known as low-pressure pipe systems) may be a viable option in situations when soil and topographical factors do not allow for the installation of a typical septic system, such as urban areas. This is especially true in cases where the geography necessitates the installation of a drain field uphill from the septic tanks or when there is uneven terrain that would otherwise impede the installation of an ordinary system. Low-Pressure Dose Systems (LPDs) are designed to function in the following ways: A pumping chamber is placed in addition to the typical septic tank, which is a type of holding tank.

  • When using an LPD application, the drain field is made up of small perforated pipes that are placed in shallow, gravel-lined trenches that are 6 to 24 inches deep and 36 inches wide.
  • After then, the field is allowed to drain.
  • Low-lying placement also encourages evapo-transpiration, in which evaporation, as well as grass and other shallow-rooted plants, aid in the removal of wastewater from the soil.
  • Alarms will be activated if there is a significant increase in flow.
  • In addition to the previously noted topographical site benefits of LPDs, there is a considerable reduction in the amount of land area required by the absorption field when compared to traditional systems.
  • Furthermore, narrow, shallow ditches help to mitigate some of the unavoidable soil compaction that occurs during the building of typical drain fields.
  • The risk of wastewater accumulating in the trenches should also be considered.
  • The inclusion of power, a pump, and a narrower drain field all raise the likelihood of system failure.

Aerobic Wastewater Treatment Systems

At this point, aerobic septic systems stand out as the only system that can be used in virtually all case where septic systems are needed. In essence, when you own an aerobic system, you are the owner of a miniature version of a municipal sewage treatment facility. In other words, your aerobic system closely resembles many of the stages and operations carried out by an urban waste treatment facility. Aerobic systems and septic systems are similar in that they both treat wastewater via the use of natural processes.

  1. The natural bacterial consumption of waste inside the system is increased as a result of the increase in oxygen.
  2. The way aerobic systems function is as follows: Pre-treatment tanks are used to catch grease, oils, toilet paper, and other solids and foreign items that are present in wastewater and effluent.
  3. Solids can clog the system and create difficulties if there are too many of them.
  4. Following that, the treated water is sent to a pumping chamber, where it undergoes a final disinfection treatment.
  5. Water is then pumped into the field and distributed through a drainfield.
  6. Systems are specifically constructed with alarms and control boxes to ensure that they are always in correct working order at any given moment.

This maintenance contract will ensure that your plant operates in accordance with specifications at all times, regardless of the weather.

Drip System

Under the majority of circumstances, conventional septic systems are sufficient for treating and disposing of household wastewater. However, when soil conditions or the surrounding region are not suitable for handling the volume of effluent generated by a standard septic system, an alternate system, such as a drip system, may be the best solution. A typical system relies on gravity to carry wastewater, and as a result, the effluent is not distributed uniformly over the drain field as effectively as it may be.

  1. It is possible for the soil in the drain field to become saturated during periods of excessive water consumption by the home, reducing the ability of the drain field to process the wastewater produced.
  2. The use of a drip system eliminates these two disadvantages of the traditional gravity-fed system.
  3. The dosing chamber is a separate tank that accepts wastewater from the septic tank and processes it.
  4. A pressure dosage system is what this is referred to as.
  5. When effluent is applied consistently and at predetermined intervals, the soil is less likely to get saturated, which allows the soil to perform more efficiently while also lasting for a longer duration of time.
  6. Homeowners should not wait until the alarm system detects a problem; instead, they should consistently follow recommended maintenance practices to ensure that the system continues to function properly for the longest period of time possible.
  7. It is in the best interests of the homeowner to ensure that the septic system is properly maintained.

What Are The Different Types of Septic Systems, Type 1, Type 2 and Type 3 System

The following things must be considered while selecting the appropriate septic system type: First and foremost, it is critical to choose the most appropriate septic system for your soil conditions; second, the system must be large enough to accommodate your household needs; and third, the wastewater must be sufficiently treated to ensure that the effluent discharged complies with local environmental health standards.

With so many various types of septic systems available, selecting the right one for your house may be a difficult endeavor. There are numerous different types of septic systems accessible, and within each type, there are frequently a number of alternatives to pick from.

Different Types of Septic Systems

It is possible to have three different kinds of septic systems, which are differentiated by the way they handle the wastewater that enters the system. The three types are as follows:

  • In a Type 1 Septic System, sewage is simply treated inside the confines of a septic tank before being evacuated to a drain field, where additional treatment happens naturally. Type 2 Septic System: treatment takes place in a septic tank, followed by an extra aerobic secondary treatment stage, which is often contained within a small size on-site mechanical biological packaged treatment plant, before being released to a drain field
  • And In a Type 3 septic system, sewage is treated in order to produce effluent of a higher quality standard, which is then discharged into the environment via the drain field. Type 3 septic systems are specially designed to treat sewage in order to produce effluent of a higher quality standard, which is achieved by including a disinfection process before being discharged into the environment via the drain field. An innovative on-site mechanical biological packaged treatment plant is used for the treatment process.

Let’s take a deeper look at the distinctions between each type of septic system in order to assist you determine which is the best solution for your particular circumstance.

Type 1 Septic System (Septic Tank System)

Septic systems classified as Type 1 are those installed on-site and in which the principal method of treating waste water is a septic tank or septic tank with leach field. A drainage field, which can be comprised of seepage beds, subsurface trenches, or aboveground sand mounds, can be used to dispose of the treated effluent once it has been treated. Effluent can either flow to the drain field by gravity or be pumped to the drain field under pressure, depending on the circumstances. Gravity system in the conventional sense ” data-image-caption=”Gravity septic system in the conventional manner” In both cases, the data-medium-file attribute is set to 1 and the data-large-file attribute is set to 1.

  1. They are made up of a septic tank that is built underground and that collects the wastewater.
  2. Because the tank is devoid of oxygen, it creates an environment conducive to the growth of anaerobic bacteria in it.
  3. Tank effluent drains out of the tank through a drain field and onto the surrounding soil.
  4. Normally occurring microorganisms that reside in the soil continue to break down the effluent, eradicating any hazardous bacteria and pathogens from the effluent before it reaches the groundwater.

Regular pumping of the tank is required to remove the solids (scum and sludge) that have built up in it over time.

Type 2 Septic System (Septic Tank + Secondary Treatment)

Septic systems are classified into two types: type 1, type 2, and type 3. Type 2 septic systems have an extra secondary wastewater treatment step, which is the most significant distinction between the two. As with a Type 1 system, the anaerobic bacteria in the septic tank break down the particles, which is done in the absence of oxygen. Typically, stage oxygen is supplied to the wastewater during the secondary treatment process, allowing aerobic microorganisms to grow in the system. Bacteria that are aerobic in nature break down any suspended particulates that may be present in the wastewater during treatment.

Extending Drain Field Life with Aerobic Septic Systems

Experimental evidence suggests that adding an aerobic septic system to an existing conventional gravity system may help to renew or prolong the life expectancy of the system in question. Aeration or oxygen introduced into an existing septic system may increase aerobic bacterial activity in the biomass, which may help to enhance the septic field’s performance if it is in a malfunctioning state. Although it is not quite that straightforward. Because the agitation caused by the aerating can drive suspended materials out into the septic field, a settling compartment or an extra tank may be necessary in conjunction with an effluent filter.

  1. In comparison to Type 1 septic systems, Type 2 septic systems are more efficient in treating wastewater.
  2. The depth between the surface and the confining layer or water table, as well as the quality of the soils on a land, are all essential considerations for treating wastewater.
  3. These characteristics make them particularly suitable for usage on homes with limited area.
  4. The only disadvantage is that the treatment expenses associated with a Kind 2 septic system will be greater than those associated with a Type 1 septic system, which is the most common type of septic system.
As per our Standards Practice, here is a subsection of our code: III- Type 2 effluent hydraulic loading rate and vertical separation

(I) Vertical separation for hydraulic loading rates of Type 2. Although the employment of a Type 2 treatment method is a realistic choice for many projects and locations (especially if available space is restricted), this will not always be the only viable alternative available. In some circumstances, according to the Volume II regulations, a greater vertical separation is required for Type 2 effluent hydraulic loading rates (HLR), notably for gravity distribution and demand dosing. Because Type 2 wastewater may have pathogen levels that are almost as high as those seen in Type 1 effluent, a deeper soil depth is required in order to offer sufficient soil-based treatment (especially pathogen elimination) in these situations.

  • If multiple doses are applied in a short period of time, the risk of soil saturation is higher, and the total number of pathogens applied will be proportionally higher at the higher HLR.
  • Because Type 2 treatment systems are frequently utilized as a solution for small sites, the requirements in this handbook allow for a high HLR with Type 2 effluent, which is consistent with industry practice.
  • As a result, larger HLR for Type 2 is given precedence over smaller VS in the standards.
  • This is due to the fact that at a lower HLR, the shallower VS will be sufficient for treating patients.
  • The type 2 wastewater has a consistent distribution and is ii) When timed or micro-dosing options are utilized in conjunction with Type 2 HLR, the Volume II standards allow for a narrower vertical separation.
  • They also reduce the likelihood of soil saturation by distributing dosages more evenly.
  • For further information on the hydraulic application rate, see Section III- (HAR).
  • As a result, on some soils, the standards provide a somewhat greater VS for Type 2 HLR with timed dosing than what is specified on others.

High HLR are permitted in sandmound and sandlined trench or bed systems when Type 2 effluent is utilized, and as a result, micro-dosing is necessary in these applications when high HLR are permitted.

How do Aerobic Septic Treatment Units Work?

In essence, an aerobictreatment unit is a type of “oxidizer,” which utilises excess oxygen present in waste water in order to sustain aerobic microorganisms, which in turn breakdown dissolved organic and nitrogen molecules to simple CO2 or inorganic compounds. As bacteria die off, they collect as a sludge of biological material, some of which is used to enable the production of new cells or microbes, which is essential for the system to continue to function. In the “trashtank,” ATUs separate solid waste from liquid waste.

“Typical organic components that are present in residential household wastewater include carbohydrates, lipids, proteins, urea, soaps, and detergents,” according to the drawing at the top of this page.

Domestic wastewater contains biologically bound nitrogen, sulfur, and phosphorus as well as other elements.

Type 3 Septic System (Septic Tank + Secondary Treatment + Disinfection/Filtration)

In contrast to Type 1 and 2 systems, Type 3 septic systems are custom-designed, high-capacity sewage treatment facilities that are capable of treating wastewater to a very high level, generating clear, odorless effluent with far greater water quality than Type 1 and 2 systems. It is necessary that a Type 3 septic system contain a technique of disinfection that is capable of eliminating harmful organisms from the effluent before it is released to the drain field. A Type 3 septic system is composed of the following components, which are frequently found together: Anaerobic bacteria break down waste in an oxygen-free environment in the septic tank; aerobic bacteria break down waste in an oxygen-containing environment in the second stage of a Type 2 septic system; and disinfection takes place in the third stage of a Type 1 or Type 2 septic system after the second stage.

The disinfection process might involve chemical treatment with chlorine, as well as disinfection with ozone or UV radiation.

Finally, the treated effluent is released to a drain field, where it is often subjected to pressure (i.e.

The use of Type 3 septic systems is an excellent option for properties with poor soil conditions and situations that are not appropriate for the installation of a Type 1 or Type 2 sewage system.

  • The soil depth is less than 0.5 feet (15 cm)
  • The percolation rates of the soil are either extremely slow or extremely quick
  • A lack of soil structure
  • There is insufficient room to establish a more typical septic system

The use of a Type 3 system may be preferable in situations when the circumstances are suitable for a Type 1 or 2 system, but space is severely restricted. This is because a smaller drain field is required owing to the excellent quality of the effluent released by the Type 3 system. ‘Why do we need different types of septic systems since they all fulfill the same function?’ one could wonder. Generally speaking, this is correct to a certain extent; nevertheless, the treatment efficiency as well as the water quality of the effluent released at the conclusion of the treatment process are greater in Type 2 systems than they are in Type 1 systems, and much higher still in Type 3 systems.

If possible, it is advisable to have an authorized competent expert do a full site investigation in order for them to examine the circumstances on site and calculate how much wastewater is likely to be generated by the home on a daily basis.

In order to guarantee that the system does not get overloaded and that environmental health is not compromised, they will need to design a septic system that is capable of dealing with the family’s output while also taking into consideration any restricting elements on the property.

The Sewerage System Regulation Process:

Land use management, which involves both onsite sewage disposal and subdivision operations, is supported by the Ministry of Health’s policy guidance. One of the most important objectives is to reduce, mitigate, and/or prevent possible threats to human health. These objectives are met by statutory requirements, as well as supporting policies and guidelines. – Official Government of Canada Website

Standards for Seasonal use as per Standards Practice Manual: III- 2.2.1 SEASONAL USESeasonal use systems should be installed in compliance with the Sewerage System Standard Practice Manual.

The usage of type 2 or type 3 systems in seasonal residences, such as a holiday cottage, may not be appropriate since these treatment systems are often powered by electricity and may rely on biological processes that are not capable of being sustained under seasonal conditions. In the specification of a treatment system for a seasonal home, include steps to ensure the system’s operation during periods of intermittent power supply and low water use. From the state of Washington, here is an educational film on the many types of septic systems available.

After everything is said and done, some of these systems are unquestionably more complex than others; therefore, a more comprehensive examination should be performed in order to be confident of the sort of septic system you may require for your property.

The 6 Septic Systems You Must Know — Build With a Bang

Unacquainted with the many types of septic systems available? If this is the case, you are not alone. Unless your property is directly linked to the sewer system, you most certainly have a septic system in place. Sewage treatment on site is accomplished by the use of natural processes in a septic system, which is a linked system of components residing under ground. Typically, a septic system is located in the yard of a homeowner. The most typical location for septic systems is in rural locations, where there is no access to a centralized town or city waste treatment facility or sewage treatment system.

Why Concrete Septic Tanks May Be Your Best Option

First and foremost, the septic system collects and dumps the waste generated by the home in the septic tank. The septic tank then separates and pre-treats the solid waste and oils from the wastewater before releasing them into the environment. Following that, most systems direct liquid wastewater from the septic tank onto a distribution network of porous pipes that branch out from the residence and septic tank and gradually discharge the wastewater into the soil. Some septic systems, rather than just discharging wastewater into the soil, employ pumps, disinfection products, an evaporation mechanism, or simply rely on gravity to funnel wastewater through sand or other organic material before releasing the effluent into the soil.

  1. The total square feet of drain field area required is determined by the number of bedrooms in the house and the soil type (arid or saturated), among other factors.
  2. Septic tanks are intended to serve as the initial stop in the wastewater treatment process, and they are constructed to do so.
  3. The sediments remain in the tank, while the wastewater is sent to the drain field for further treatment and dispersal when it has been treated.
  4. Concrete, plastic (polyethylene), and fiberglass are the three most common materials used in construction.
  5. Drain fields are plots of land that have been particularly engineered to assist in the filtering and removal of pollutants from wastewater.

Perforated pipes, which are buried within the trenches, are used to disseminate the wastewater from the home in a methodical manner. A standard septic system is comprised of a septic drain field, its associated pipe system, and a septic tank.

Conventional System

The majority of traditional septic systems are situated in single-family residences or small commercial establishments. A high number of individuals in a single area is not often served by traditional systems, which are not normally designed for this purpose. A typical system consists of the following components: Sewage treatment system (Septic tank) An underground wastewater infiltration system or a gravel-filled drain field can both be used to collect wastewater. Protects the clean drain field from additional possible impurities with a strong geofabric covering.

The wastewater (also known as effluent) is routed from the septic tank to the drain field in this location.

As soon as the wastewater passes through the clean drain field, it flows into the soil where it is continuously cleaned by naturally existing bacteria as it gently trickles its way through the soil layer and into groundwater.

The disadvantage is that it is difficult to install in homes with small lots.

Chamber System

As a viable alternative to the more frequent gravel field technique, chamber systems have been in use since the 1970s. It is common to employ chamber systems in places where the water table is high, as they reduce the likelihood of poor drainage and messy back-ups. Another need for this system is a sequence of linked pipelines and chambers, with the chambers being completely enclosed by soil. The septic pipes transport wastewater from the home to the septic tank, which subsequently transports the wastewater to the chambers.

During the last stages of wastewater treatment before it is discharged into a storm drain, bacteria in the soil release the treated wastewater into the soil as it flows downward toward the groundwater table.

The disadvantage of using an extra chamber instead of a more standard drain field is that there is an increased risk of additional maintenance.

Aerobic Treatment System

Aeration of wastewater in a septic treatment tank is accomplished by the use of aerobic treatment equipment. The infused oxygen in the wastewater aids in the addition of nutrients to the wastewater as well as the efficient start of the treatment process itself. Aerobic systems are available with tanks that may be used for both pretreatment and final treatment, as well as systems with two distinct tanks for pretreatment and final treatment, among other options. The ultimate objective is to treat and disinfect in a safe and efficient manner, without causing harm.

Advantage: This is particularly useful in locations with high water tables or in areas where there is insufficient land to construct a good drain field. The disadvantage of using an aerobic system is that, like the drip distribution system, it requires regular maintenance.

Drip Distribution System

Aeration of wastewater in a septic treatment tank is accomplished by the use of an aerobic treatment system. With the addition of oxygen to the wastewater, nutrients may be added, allowing the treatment process to begin more quickly. Aerobic systems are available with tanks that may be used for both pretreatment and final treatment, as well as systems with two distinct tanks for pretreatment and final treatment, as described above. The ultimate objective is to treat and disinfect in a safe and efficient manner, without compromising quality.

Maintenance with an aerobic system is required, just as it is with a drip distribution system.

Sand Filter System

Sand filter systems allow waste water to travel from a septic tank to a pump chamber, and then from the pump chamber to the sand filtering system. Sand filter systems are used in conjunction with septic tanks. The sand filtration system is essentially a big concrete box that is filled with sand to filter out contaminants. Following a leisurely pumping operation to the top of the box, the waste water is filtered through the sand, which treats the water prior to its discharge into the soil absorption region (see illustration).

Cons: Frequent maintenance is required.

Evapotranspiration System

In contrast to conventional septic systems, the Evapotranspiration System’s drain field is housed in a closed, waterproof field that is covered with layers of gravel and sand to keep out the elements. Once the wastewater has passed through the septic tank and into the waterproof drain field, it begins to evaporate slowly. It is important to note that, unlike other septic systems, the effluent never filters into the soil. When compared to the alternatives, the ease of installation, maintenance, and use is superior.

Benefits: The ease of use is excellent, and the difficulty of installation and maintenance is minimal.

Mound System

The mound system consists of the construction of a big sand mound that serves as a drain field. A controlled flow of wastewater is maintained throughout its journey from the septic tank to a chamber where it is pushed through to the mound. After flowing through a mound trench and percolating through the sand, the wastewater eventually trickles into the ground. Among those who live in rural locations where there is a lot of land but little absorbent soil, the mound system is a popular alternative.

Cons: It takes up a lot of room and requires a lot of upkeep.

In any case, count on having your septic tank examined once per year and pumping it at least once every six months, regardless of the system you have in place. Solid waste matter can block the pump and cause damage to the drain field if it is not pumped on a regular basis.

Garbage Disposal With Septic

Unless you reside in a septic-equipped home, it is better not to have a trash disposal. The increased volume of solid waste material will necessitate more frequent septic tank pumping and may erode the drain field, resulting in sewage back-ups in the future. Those who live in homes with septic systems may find that they must be extra cautious about what they flush down the toilet. Certain common home objects, when flushed down a toilet connected to a septic system, can create clogs, backups, and even damage to the system, resulting in not only discomfort and aggravation, but also a significant financial burden.

Chemicals may cause significant damage to and contamination of surface and groundwater, which can result in disease or even death in animals and people who consume the water.

4 Types of Septic Tanks – HomeAdvisor

The characteristics of each type of septic tank are crucial to understand whether you’re deciding which type of tank to use in conjunction with your septic system or solving a problem with your existing tank. Each installation option has its own set of pros and limitations, just like any other installation. Knowing the relative advantages and disadvantages of each option will assist you in making the right selection while establishing, repairing, or replacing your septic tank. Please keep in mind that most of these issues are the consequence of improper septic maintenance or installation.

The cost of an inspection might vary significantly based on a variety of criteria.

  • Solid Waste Container— Solid waste containers made of concrete are prone to cracking and even separation. These fissures, which are usually extremely durable for several decades, might appear sooner if a poor quality concrete mix was used or if the septic system has not been adequately maintained. These gaps will allow effluence (waste) to leak out of the concrete septic tank and/or allow groundwater to seep in through the tank’s drainage system. Either scenario is undesirable. The system may get clogged as a result of a blockage. Runoff is harmful, but it will not be discovered by a typical dye test since it is invisible. If a concrete septic tank is not physically inspected, it is possible that the problem will not be discovered until it is too late and major difficulties have developed. Tanks made of steel are the least long-lasting and most unpopular of the available tank options. They are intended to survive no more than 20-25 years, although they can succumb to rust even earlier than that. Steel top covers have the potential to rust through, allowing an unwary individual to fall into the tank. It is possible to change these covers without having to replace the complete tank. If you’re purchasing a property or already live in one that has a steel septic tank cover, personally viewing the cover will not necessarily provide you a clear indicator of the general state of your tank in the long run. As with any septic tank, pay particular attention to the baffles (entry and exit points) because they are the first to corrode in most cases. Fiberglass/Plastic Septic Tank—Unlike steel and concrete septic tanks, plastic septic tanks are virtually immune to the corrosion and cracking that occurs in steel and concrete septic tanks. Nonetheless, they have their own set of difficulties that should be kept an eye out for. In some cases, a low effluent level might indicate that a blockage at the bottom of the tank has gotten dislodged. Pumping should be performed even if the effluent level seems to be normal throughout the process
  • Nevertheless, any clogs should be carefully checked after the pumping. It is possible that the process of pumping a septic tank will be sufficient to remove a clog.
  • In spite of the fact that plastic septic tanks are more resistant to the chemical processes that occur naturally in a septic system, their lower weight makes them more prone to structural damage. It is necessary to install the tank with care in order to avoid damage to the tank. It is important to take careful notice of the land above the tank. Avoid driving any vehicles over the tank’s filling station. During periods of wet soil, the lighter can also cause the tank to shift in its position in the ground. Occasionally, a plastic septic tank may emerge from the earth, destroying pipes along the way.
  • Using oxygen to help in the degradation of the effluent is what aerobic septic tanks are all about, according to the manufacturer. They also necessitate the use of power. When a septic system fails, aerobic septic tanks are most frequently utilized to replace it. They can also, on occasion, minimize the amount of space necessary for their drain field. Aerobic septic tanks are generally two to three times more expensive than conventional septic tanks, but their high efficiency can result in significant savings in terms of reclaimed land in the drain field and a longer tank life. The capacity of an aerobic septic tank to function has nothing to do with its long-term dependability. A more regular and more thorough maintenance schedule is required for an aerobic septic system. Because of its more intricate breakdown structure, there is a greater possibility that something may go wrong. However, if the system is properly maintained, its effectiveness will allow you to keep your effluent under control for an almost unlimited period of time.
  • Important Caution: Exercise extra caution when in the vicinity of open or uncovered sewage tanks. Falling into a sewage tank will almost always result in death due to asphyxiation. The simple act of leaning over a septic tank might lead you to pass out.

Septic System Types

Traditional septic systems and alternative septic systems are the two most common types. The sort of system that should be implemented is typically determined by the site and soil conditions that exist. Please contact the onsite program staff at 360-867-2673 if you require any further information.

Because your septic system is your responsibility, it is critical that you understand the sort of system you have and how to properly maintain it. In the next section, we’ll give you a quick overview of the most prevalent types of septic systems.

Gravity System

Known as a basic or standard system, gravity is used to carry wastewater through the septic tank and out into the drainfield. Gravity System.

Pressure Distribution System

It is equipped with a pump that simultaneously distributes wastewater throughout the drainfield. It is used in the majority of new systems because it makes greater use of the complete drainage system. Additional information may be found atPressure Distribution System.

Aerobic Treatment Unit (ATU)

Because it makes use of oxygen to break down particles, it produces cleaner effluent than conventional methods. In environmentally sensitive places where wastewater requires further treatment before entering the drainfield, this method is frequently utilized. Additional information may be found at Aerobic Treatment Units (ATUs).

Mound System

Drainfields are elevated above ground level when there is just a little amount of soil available for treatment to use. For further information, seeMound System.

Sand Filter System

It is equipped with a sand filtering system and a pump for treating and discharging wastewater, and it is utilized when just a little amount of soil is available for treatment. Sand Filter System. The Washington State Department of Health has published a document named “List of Registered On-Site Treatment and Distribution Products” that contains the most up-to-date information on proprietary sewage products certified by the state of Washington.
