Eco-Septic recommends the use of concrete tanks in both residential and commercial settings, as they are generally the best septic systems due to their watertight and durable structure.
How do I choose the best septic tank design?
- Determine your size requirements. Before looking at septic systems,figure out what size of septic tank is right for your home.
- Decide what type of septic tank design is best. Don’t think in terms of brand name,but what type of soil your septic tank will be installed into.
- Select the pump type you will use.
What type of septic tank is the 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 is the most cost effective septic system?
Conventional septic system These conventional septic systems are usually the most affordable, with an average cost of around $3,000.
What is the longest lasting septic system?
Concrete septic tanks have the longest lifespan out of any septic tank material. While they are more expensive and sometimes difficult to install, it is for a good reason. A properly designed and installed concrete septic tank can last for anywhere from 40 years and beyond.
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 often should a 1000 gallon septic tank be cleaned?
For example, a 1,000 gallon septic tank, which is used by two people, should be pumped every 5.9 years. If there are eight people using a 1,000-gallon septic tank, it should be pumped every year.
How long does a 1000 gallon septic tank last?
A septic tank depends largely on the pump and the family usage. That is, a 1,000-gallon tank would most likely last more than 20 years (on average), while a 500-gallon tank might only last 10-15 years under similar conditions.
What is the alternative to a septic tank?
Mound systems work well as alternatives to septic tanks when the soil around your home or building is too dense or too shallow or when the water table is too high. Although they are more expensive and require more maintenance than conventional systems, mound systems are a common alternative.
How long does a leach field last?
It’s important to consider the life expectancy of a drain-field, too. Under normal conditions and good care, a leach-field will last for 50 years or more. Concrete septic tanks are sturdy and reliable but not indestructible.
How big of a septic tank do I need?
The larger your home, the larger the septic tank you’re going to need. For instance, a house smaller than 1,500 square feet usually requires a 750 to 1,000-gallon tank. On the other hand, a bigger home of approximately 2,500 square feet will need a bigger tank, more than the 1,000-gallon range.
What is the average life of a septic system?
Age of the System It’s pretty common for a septic system to last 40 years or longer, which means if you buy a new home, you might never need to replace it. However, you might have an older home whose septic system has been in place for nearly half a century.
How can I make my septic tank last longer?
How to Keep Your Septic System Healthy
- How the Septic System Works.
- Don’t Overload the Septic Tank and Drain field.
- Use an Efficient Toilet.
- Don’t Treat the Toilet as a Garbage Disposal.
- Don’t Pour Grease Down the Drain.
- Divert Rain Water From the Septic Drain Field.
- Keep Trees Away from the Septic System.
How often should a septic tank be replaced?
Typical lifespan is in excess of 30 years for GRP, PE and concrete tanks. Assuming optimal conditions of install and use, you could expect the following: Steel septic tanks have a life expectancy of 15 to 20 years.
How much does it cost to pump a septic tank?
How much does it cost to pump out a septic tank? The average cost is $300, but can run up to $500, depending on your location. The tank should be pumped out every three to five years.
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.
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.
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.
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.
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.
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.
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.
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
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.
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.
- 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.
- Septic tanks are intended to serve as the initial stop in the wastewater treatment process, and they are constructed to do so.
- 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.
- Concrete, plastic (polyethylene), and fiberglass are the three most common materials used in construction.
- 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.
The majority of conventional septic systems are found in single-family residences or small commercial establishments. A large number of people in a single location is not typically served by conventional systems, which are not typically designed for this purpose. A conventional 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 other potential contaminants with a strong geofabric layer.
The wastewater (also known as effluent) is piped 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 treated by naturally occurring microbes as it slowly trickles its way through the soil layer and toward groundwater.
The disadvantage is that it is difficult to install in homes with small lots.
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
It is not necessary to install a standard gravel-based drain field since the Drip Distribution system makes use of an underground snaking system of distribution pipes that are installed near the surface of the soil. Pipe laterals for the drip distribution system are buried in shallow ground soil, generally 6 to 12 inches below the surface of the ground. Because it eliminates the requirement for a standard drain field, this technique reduces the amount of digging required and makes it easier to reach plumbing within the drain field.
A second tank, referred to as a dosage tank, is required to take wastewater after it has passed through the septic tank in order to handle this technique.
However, in order for this to happen, the dosage tank must be connected to power.
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.
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.
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.

The Key Factors In Deciding The Best Septic System For Your Home or Lot
When a new house is being constructed or an existing septic system is being renovated, one of the most commonly asked questions is ‘what septic system is the most effective?’ The answer is not straightforward since it is dependent on a number of different circumstances. In certain cases, the greatest septic system for one property may not be the best septic system for another. Some significant considerations that must be made before choosing on which septic system is most appropriate for a given site are mentioned in the following section.
Soil TypeLoading Rates
The soil properties of a property, as well as the volume of sewage that will be created by the home, will play a significant role in determining the optimum septic system for that location. The kind of soil has a considerable impact on percolation rates, and the amount of wastewater produced by the home should also be taken into consideration, since the septic system must be able to handle the volume of wastewater that is generated. It is necessary for the effluent flowing into the drain field to be able to flow through the soil at a fast enough rate to prevent it from gathering and rising to the soil surface, where it can pond and represent a threat to both the environment and human health in order for it to be effectively treated.
After all is said and done, the type and size of septic system will be determined by the soil loading rate, which is the rate at which effluent is expected to pass through the soil (gallons per day / square foot).
The soil loading rate is influenced by the structure and texture of the soil, among other factors.
As a second requirement, there must be sufficient soil depth between the wastewater penetrating surface and the water table, as well as any other restricting layers or elements such as bedrock, restrictive soils, or water bodies, in order to ensure that effluent is properly treated by bacteria in the soil before it can be discharged into either the groundwater or a freshwater body. a variety of soil types ” data-medium-file=” ssl=1″ data-large-file=” ssl=1″ loading=”lazy” src=”is-pending-load=1 038;ssl=1″ alt=”” width=”451″ height=”309″ ” data-large-file=” ssl=1″ loading=”lazy” src=” is-pending-load=1 038;ssl=1″ width=”451″ height ” data-recalc-dims=”1″ data-lazy-src=” is-pending-load=1 038; ssl=”” srcset=”data:image/gif;base64,R0lGODlhAQABAIAAAAAP” data-recalc-dims=”1″ data-lazy-src=” is-pending-load=” is-pending-load=1 038; ssl=”” data-recalc a variety of soil types Depending on the depth of the soil that naturally occurs on site, it may be necessary to artificially increase the depth of the soil through the installation of a sand filter and/or an above ground sand mound in order to ensure that proper treatment takes place before the effluent reaches the restricting layer.
Poly Septic Tank vs Concrete Septic Tank
Another typical conundrum when choosing on the finest septic system for a site is determining whether to go with a concrete or plastic septic tank — polypropylene or high-density polyethene (HDPE) — septic tank for the property. However, while both types are appropriate, there are advantages and downsides to using each.
Plastic Septic Tanks
In comparison to concrete tanks, plastic (polypropylene and high density polyethylene) tanks are inexpensive, lightweight, and exceptionally durable; they are corrosion resistant and, unlike concrete, are not prone to cracking. They are less expensive to transport than concrete tanks, and they are simpler to move on a construction site without the need for specialist equipment, resulting in a lower cost of installation.
Chemical storage tanks made of polypropylene or high-density polyethylene (HDPE) are inexpensive and lightweight while being exceptionally durable – they resist corrosion while remaining waterproof and not prone to splitting, unlike concrete tanks. These tanks are less expensive to carry than concrete tanks, and they are also easier to maneuver on a construction site without the need for specialist equipment, making them less expensive to build.
Concrete Septic Tanks
Although concrete tanks are available in a variety of sizes, bigger prefabricated tanks are more readily available for storage of considerably greater amounts. They are also incredibly resilient, and because they are so heavy, they will not float to the surface of the water like other types of floating objects. Concrete septic tanks are also capable of withstanding larger depths; in colder climates, deeper tanks are frequently required.
These tanks are more difficult to install than plastic tanks because concrete is so heavy. They require site access for a huge delivery truck equipped with a crane, which increases installation expenses, making them more expensive than plastic tanks.
Inasmuch as the tank lid is not put until after the concrete tank has been set in the ground, it is possible for severe leaks to occur if the lid is not correctly sealed. Concrete is also susceptible to cracking, which can result in leaks forming.
Alternate Septic Sytems
As settlements are pushed further out from city borders, or, to put it another way, as lot sizes become more constricted as everyone strives to have a spectacular view of the lake. As a result, septic systems are forced to operate outside of the norm. Consider the following scenario: a property by the lake is acquired; the lot is not very huge, but the homeowner has a family and so demands a large residence. Because the soils contain larger percentages of sands, they are suitable for a standard gravity septic system.
- We don’t have enough space in the rear to accommodate such a system, and the front yard is not a concern for any septic system that could be installed in the future.
- You see, with a normal septic system, the septic tank is responsible for the majority of the treatment, with the remainder being handled by the soils.
- Generally speaking, a Type 1 Septic system is what you are looking at here.
- Because of the higher quality oxygenated wastewater, we are able to operate in a less space than before.
- There are various septic drain field technologies that can create Type 2 effluent as well, and a Type 1 effluent septic system can often be developed in conjunction with a Type 2 Septic system.still confused?
- If aerobic treatment does not enable us to conform to the size of the yard, we will need to consider adding extra treatment, which might include UV light or chlorination, to make up for the difference.
In order to gain a good view of the lake from every location, projects are being pushed further out from municipal borders or, to put it another way, lot sizes are becoming more constricted. Consequently, septic systems are forced to operate outside of the norm. Consider the following scenario: a property near a lake is acquired; the lot is not very large, but the homeowner has a family and so demands a larger home than the property allows. But wait, there’s more. The soils include larger percentages of sands, making them perfect for a standard gravity septic system.
- In this scenario, however, the wastewater quality must be enhanced.
- Given the lower efficacy of this sort of system in terms of wastewater treatment, a larger surface area is necessary for safety purposes.
- After that, ATUs (Aerobic Treatment Units) are employed to improve the quality of the effluent that exits the tank regions, as in the example above.
- Septic systems classified as Type 2 are those that are designed to handle the waste generated by the human body.
- While there are many different methods to identify the appropriate approach for certain issues, no two parcels of land or homes are exactly same.
The use of aerobic treatment alone may not be sufficient in order to correspond to the size of the yard, and we may be forced to consider adding additional treatment, such as UV light or chlorination. Generally speaking, this sort of septic system falls under the classification of Type 3.
What is the Best Septic System?
Septic systems are available in a variety of configurations and configurations. They all have advantages and disadvantages, and they have all been developed for usage in various situations. The amount of wastewater that the household is anticipated to create, as well as limiting elements such as soil type and loading rates, as well as any restrictive layers present on the site, should all be taken into consideration when determining the optimum septic system for the home. However, both plastic and concrete tanks have their advantages and disadvantages; ultimately, the choice will be determined by the wastewater practitioner’s and homeowner’s preferences and budget, and/or whether or not they are permitted for use in the region where the installation will take place.

Tips for Choosing the Best Septic Tank
Septic tanks are most commonly found in rural settings. These enormous tanks, which serve as an alternative to sewage systems, aid in the filtration of both solid and liquid waste. Most of the time, septic tanks are installed underground in a yard area near to the residence. It is into this tank that all of the drains from the sinks, showers, and toilets run, after which they are filtered. During the process of filtration, heavier debris sinks to bottom of the tank, while the filtered water and liquid subsequently exits the tank, where it drains into a predetermined region It is a cost-effective method of managing the sewage from your home without the need to install sewage lines in your home’s plumbing.
There are a variety of septic tanks available in a variety of various sizes. The size of your water tank should be chosen by the amount of water your household consumes on a daily basis. If your household only consumes a little amount of water (less than 500 gallons per day), a septic tank with a capacity of 900 gallons is required to ensure that the sewage is adequately treated.
If you have a family that uses between 500 and 700 gallons of water each day, you should consider a tank with a minimum capacity of 1,200 gallons. In certain regions, local ordinances may specify the size of the tank that must be installed at each house.
While the basic concepts of septic tanks remain the same, there are a variety of different designs to select from. In the event that your tank will be put in an area with gravel or coarse soil, a pressure-type septic system is the most appropriate option. It is preferable to use a gravity system in places with rich soil or dirt. These let streams of untreated sewage to seep into the ground, enriching the soil in the surrounding area and contaminating it. In the same way that there may be limits on the size of your home, there may also be restrictions on the sort of septic system you are permitted to install depending on where you live.
Pumps are used in all septic systems, regardless of their size or design. There are two types of pumps used in septic systems. A turbine pump is believed to be preferable to a reciprocating pump because it is more dependable and has a longer life span on average. However, as a result of their enhanced dependability, they are frequently more expensive than other options. A centrifugal pump may not last as long as a reciprocating pump, but it is significantly less costly. Turbine and centrifugal pumps are both available in a variety of sizes, making it simple to choose the one that is most appropriate for your tank.
The best course of action is to talk with a contractor if you are uncertain about which pump, design, and tank size will be most appropriate for the size of your property.
Furthermore, they may assist you in better understanding the scope of the project and what to expect during the installation process.

What Types of Septic Systems Are There and What Do They Offer?
Before you employ septic installation services, you must first choose which sort of septic system is most appropriate for your requirements. This selection will have significant ramifications, impacting the design of the septic system, the requirements for septic system installation, the efficiency of the system, and other factors. In order to assist you in making your decision, we will go through five distinct types of septic systems and their characteristics in the following paragraphs.
1. Septic Tanks
A septic tank is a waterproof tank that is buried in your backyard that absorbs and partially processes raw household sanitary water before being released back into the environment. Due to the fact that the solid wastes settle at the bottom of the tank and the grease and lighter solids rise to the top, the wastewater that accumulates in the tank is released to the drainfield, where it is further cleaned and distributed. In addition to other forms of septic systems, the septic tank is an important component.
By connecting it to an air pump, it may also be converted into an aerobic system for exercise. The latter introduces oxygen into the tank, enhancing bacterial activity and, implicitly, the efficiency of the wastewater treatment process.
2. Conventional Systems
Septic tank systems connected to a drainfield or a subsurface wastewater infiltration system are examples of wastewater treatment assembly systems. In order to transport the water from the tank, it is piped to a shallow trench of gravel or stone that is constructed directly beneath the ground surface. Geofabric is used to cover the trench to keep dirt, sand, and other pollutants from penetrating the space underneath it. The wastewater is filtered as it flows through the gravel or stone layer, thus the term “infiltrator septic system,” and it is further cleaned by the bacteria in the soil underneath the trench, which is referred to as the “infiltrator” in the name of the system.
As a rule, drainfields have a somewhat big footprint, making them unsuitable for many residential applications.
3. Chamber Systems
Gravelless drain fields, which have been in widespread use since the 1970s, are now a popular alternative to conventional gravel septic systems. From open-bottom chambers and fabric-wrapped pipes to synthetic materials such as expanded polystyrene, there are a variety of solutions available to choose from. It is crucial to highlight that it is feasible to construct gravelless systems out of recycled materials, so reducing their impact on the environment and saving money. A gravelless system is used in the chamber system.
Additionally, because they may be put in places with high groundwater levels and changeable septic system influent volume, they are a great solution for vacation properties and seasonal inns.
4. Drip Distribution Systems
These are effluent dispersal devices that may be used in a variety of drainfield configurations. Many homeowners favor them since they do not need the construction of big mounds of earth. Their drip laterals are installed at a depth of 6 to 12 inches below the surface of the soil. One downside of these sorts of septic systems is that they necessitate the installation of relatively large dosage tanks following the septic tanks in order to permit the wastewater’s timed-dose distribution to the drip absorption regions, which can be costly.
5. Mound Systems
In places with high groundwater, shallow soil depth, and shallow bedrock, these septic system types are more frequent than in other areas. They are made up of a sand mound that serves as a shelter for a drainfield trench. Septic tank wastewater is released into a pump chamber, from which it is pushed to the mound in predetermined dosages and filtered via the trench and sand layer prior to being spread into the surrounding soil.
Even while mound systems might be an effective option for specific soil conditions, they take up a lot of space and require regular maintenance.
Let Specialists Recommend the Best Septic Systems for Your Home!
Homes owners frequently believe that simply because they have seen a sewer system diagram or various different types of septic tanks installed, they are capable of making the best decision for their home’s sewage system. Some people even go so far as to hunt for information on how to construct a septic system and consider taking matters into their own hands to solve the problem themselves. That is not something we recommend.

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.

What is the best septic system for clay soils?

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?
It is common for an aseptic tank to discharge around one-third of its contents down the drainfield. In order for the water to move through this system and be somewhat cleansed by the soil, it must pass through small crevices in the soil, leaving any trash or undesired materials in the ground as it does so. It is impossible for water to move through clay soil because there aren’t large enough spaces between the particles of the soil (hence the dry baked ground in hot weather, and water-logged garden during rainy spells).
Due to a lack of movement of the water, despite its removal from the septic tank, unclean untreated water collects around the tank and creates a sodden path.
Aerobic Septic Systems
Conventional septic systems and aerobic septic systems are the two types available. Both systems achieve the same end result (sewage breakdown and effluent treatment), but the methods by which each system accomplishes that aim are distinct from one another.
Conventional Septic Systems
The design of conventional septic systems is less complex than that of aerobic systems. Solid waste is introduced into a septic tank and settles at the bottom, resulting in the formation of sludge. Similarly, liquid waste enters the same septic tank and floats to the top of the tank, resulting in the formation of a layer of scum. Anaerobic bacteria in the tank aid in the breakdown of both liquid and solid waste, resulting in wastewater that may need to be treated in a second tank before being discharged to the drain field.
Aerobic Septic Systems
Aerobic septic systems are more complicated and expensive to install. They are divided into three compartments: a waste tank, a treatment plant, and a pump tank, among others. All three compartments can be contained beneath a single unit or fitted as separate units, depending on your preference. Like typical septic systems, liquid and solid waste enters the trash tank and settles into layers, creating a layered structure. The difference comes when wastewater is transported to the treatment facility, where an aerator, which functions similarly to a fish tank pump, pumps oxygen bubbles throughout the effluent.
The additional oxygen is necessary to achieve this goal.
From here, it is deemed ecologically safe enough to be applied to surface vegetation prior to the ultimate phase of treatment, which is absorption into the surrounding soil.
The Texas Waste Co. can supply pumping trucks and waste disposal support for your local plumber or septic system service provider for routine cleaning or emergency repair on both conventional and aerobic septic systems, as well as for your home or business.
Alternative Septic Systems For Difficult Sites
This Article Discusses Mound Systems are a type of system that is used to build mounds. Alternative Systems are also available. View and post commentsQuestions Septic System FAQsView all articles on the SEPTIC SYSTEM If your lot does not pass the perc test, some towns may enable you to construct an engineered system as a backup plan if the perc test fails. For waterfront estates and other ecologically sensitive places, alternative water-treatment systems may also be necessary to aid in the protection of water supplies.
- A “mound” system operates in much the same way as a normal system, except that the leach field is elevated above the natural grade.
- They require more frequent monitoring and maintenance in order to avoid complications.
- It is possible that the technology will not operate as planned if either the designer or the installer is inexperienced with the technology.
- The design of a system is particular to the soil type, site circumstances, and degree of consumption that is being considered.
- Some states and municipalities will only accept system types that have been certified in their jurisdiction, and they may also demand that the owner maintain a service contract with a vendor that has been approved by the state or municipality.
Mound systems are often two to three times more expensive than ordinary septic systems, and they need more frequent monitoring and maintenance. To see a larger version, click here. Ohio State University Extension provides the following information: The mound is comprised of a network of tiny distribution pipes that are embedded in a layer of gravel on top of a layer of sand that is normally one to two feet deep. Topsoil is applied to the tops and sides of the structure (see illustration). A dosing chamber (also known as a pump chamber) is included in a mound system, and it is responsible for collecting wastewater that is discharged from the septic tank.
Most feature an alarm system that notifies the owner or a repair company if the pump fails or if the water level in the tank increases to an unsafe level.
Aside from that, monitoring wells are frequently placed to keep track on the conditions inside and outside the leach field.
The most expensive items are the additional equipment, as well as the earthwork and other materials that are required to construct the mound.
In extreme cases, a mound system can cost more than $20,000 in some locations. Additionally, owing of the increased complexity, mound systems need more regular pumping as well as additional monitoring and maintenance. In certain cases, annual maintenance expenditures may exceed $500.
OTHER ALTERNATIVE SEPTIC SYSTEMS
Sand filters that do not have a bottom are frequent on coastal properties and other ecologically sensitive places. There is a large variety of alternative septic systems available on the market, with new ones being introduced on a regular basis. Some are designed at community systems that serve a number of houses, and they are often monitored and maintained by a professional service provider. Some alternative systems are well-suited to particular houses, albeit the costs, complexity, and upkeep of these systems must be carefully evaluated before implementing them.
Before the wastewater reaches the leach field, which serves as a miniature replica of a sewage-treatment plant, some larger community systems employ pre-treatment to reduce the amount of bacteria present.
There are numerous other versions and combinations of systems and components that may be employed, including the following:
- Pressurized dosing: This method makes use of a holding tank and a pump to drive effluent through the distribution pipe in a more uniform and regulated manner, hence boosting the effectiveness of the leach field. When used in conjunction with other techniques, such as a mound system, a sand filter, plastic leach fields or drip irrigation, it can be used to rehabilitate a leach field
- However, it should not be used alone.
- Septic system with alternative leach field made of plastic: This is a normal septic system with an alternative leach field that may be shrunk in some jurisdictions, making it ideally suited for tiny construction sites. Because the half-pipe plastic chambers provide a gap for effluent flow, there is no need for gravel in the system. Infiltrator System, for example, has been in service for more than two decades and, according to the manufacturer, can withstand traffic volumes with only 12 inches of compacted cover. The higher cost of the plastic components is somewhat countered by the lower cost of gravel and the smaller area of the drain field, respectively.
- Sand filter: This is a big sand-filled box that is 2-4 feet deep and has a waterproof lining made of concrete or polyvinyl chloride (PVC). Using filtration and anaerobic microorganisms, the sand is utilized to pre-treat wastewater before it is discharged into the leaching field. The boxes are often partially or completely buried in the ground, although they can also be elevated above ground level as necessary. While a pump and controls are typically used to equally administer the effluent on top of the filter, gravity distribution is also viable in some instances. The most common setup is shown in Figure 1. A collection tank at the bottom of the tank collects the treated effluent, which is either pumped or gravity-fed to the drain field. Some sand filters recycle the effluent back to the tank multiple times before discharging it into the drain field, while others do not. The majority of sand filters are used for pre-treatment, although they can also be utilized as the primary treatment in certain situations. A “bottomless sand filter” is used in this situation since the effluent drains straight into the soil underneath the filter (see photo above). A well designed and manufactured sand filter that is regularly maintained will prevent sand from being clogged on a consistent basis. More information about Sand Filters may be found here.
- Aerobic treatment system: These systems treat wastewater by the use of an aerobic process, which is normally carried out in an underground concrete tank with many chambers. Aeration, purification, and pumping of the effluent are all accomplished through the use of four chambers in the most complicated systems. The first chamber functions similarly to a smaller version of a regular septic tank in its function. An air pump is employed in the second “treatment” tank to ensure that the effluent is continually injected with fresh air. The presence of oxygen promotes the growth of aerobic bacteria, which are more effective in processing sewage than the anaerobic bacteria found in a standard septic system. It is possible to utilize a third and fourth chamber in certain systems to further clarify the water and to pump out the purified water. In addition, so-called “fixed-film” systems make use of a synthetic media filter to help the bacterial process go more quickly. In the correct hands, aerobic systems may create better-quality wastewater than a typical system, and they may also incorporate a disinfectant before the purified wastewater is discharged. A smaller drain field may be used in urban areas while a larger area may be sprayed across a whole field in rural areas. Technically speaking, they are tiny sewage treatment plants rather than septic systems, and they rely mostly on anaerobic treatment to accomplish their goals. They are referred to as ATUs in some circles (aerobic treatment units). Installation and maintenance of these systems are prohibitively expensive
- As a result, they are mostly employed in situations where high-quality treatment is required in a small area or with poor soils. A growing number of them are being built on beachfront sites. More information about Anaerobic Treatment Systems may be found here.
- Using a pump, wastewater is sent via a filtering mechanism and onto an array of shallow drip tubes that are spaced out across a vast area for irrigation. In order to send reasonably clean water to the system, a pretreatment unit is often necessary. Alternatively, the water may be utilized to irrigate a lawn or non-edible plants, which would help to eliminate nitrogen from the wastewater. This sort of system may be employed in shallow soils, clay soils, and on steep slopes, among other conditions. Frozen tubes can pose problems in cold areas since they are so close to the surface of the water. Expect hefty installation fees, as well as additional monitoring and maintenance, just as you would with other alternative systems.
- Wetlands that have been constructed. These are suitable for those who are environmentally conscious and wish to take an active role in the recycling of their wastewater. They may be used in practically any type of soil. An artificial shallow pond is used in the system, which is lined with rock, tire chippings, or other suitable medium and then filled with water. A pleasant atmosphere is created by the media, which serves as a habitat for particular plants that process wastewater and maintain the ecosystem. Wastewater from the septic tank is dispersed across the media bed through a perforated conduit, where plant roots, bacteria, and other microorganisms break down the contaminants in the water. The treated water is collected in a second pipe located at the back of the marsh. Household members must budget time for planting, pruning, and weeding in the wetlands area.
