How Deep Is A Vault Style Septic Tank? (TOP 5 Tips)

inspectapedia.com

• The surface of the tank is about 2 feet underground. The entire tank goes down deeper about 6-7 feet. Soon I have to start digging around the side of the tank to look for the outlet.

What is the standard depth of a septic tank?

Tanks are typically buried 4 inches to 4 feet deep depending on local site conditions, shape, slope, and other factors. Here is the basic math for computing septic tank capacity (volume) in gallons. Measurements are in feet, taken of inside dimensions of the septic tank.

How deep are septic laterals buried?

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

How does a septic vault work?

Septic tanks work by allowing waste to separate into three layers: solids, effluent and scum (see illustration above). The solids settle to the bottom, where microorganisms decompose them. The middle layer of effluent exits the tank and travels through underground perforated pipes into the drainage field.

How big is an underground septic tank?

Underground septic tanks are available in sizes ranging from 200 gallons up to 1500 gallons. An inlet and outlet may be added to tanks sized 200 gallons to 500 gallons for $75.00.

Can a septic tank be too deep?

Keep septic tanks high: we don’t put the septic tank any deeper than necessary, since we are usually moving effluent from the septic tank to the drainfield also by gravity. Plumbers usually install sewer lines to slope down from inlet to outlet, at 1/8″ per foot to 1/4″ per foot of linear run of the waste pipe.

How deep are drain fields buried?

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

Can a leach field be too deep?

Drain Field Depth The result is a drain field about 3 to 4 feet deep. Sometimes, however, a drain field may need to be a bit shallower and can result in drain pipes as close to the surface as 6 inches. Underground obstacles can cause this situation.

What can you put on top of a septic field?

Put plastic sheets, bark, gravel or other fill over the drainfield. Reshape or fill the ground surface over the drainfield and reserve area. However, just adding topsoil is generally OK if it isn’t more than a couple of inches. Make ponds on or near the septic system and the reserve area.

What are the signs that your septic tank is full?

Here are some of the most common warning signs that you have a full septic tank:

• Your Drains Are Taking Forever.
• Standing Water Over Your Septic Tank.
• Bad Smells Coming From Your Yard.
• You Hear Gurgling Water.
• You Have A Sewage Backup.
• How often should you empty your septic tank?

How do Imhoff tanks work?

The Imhoff tank is a primary treatment technology for raw wastewater, designed for solid-liquid separation and digestion of the settled sludge. Gas produced in the digestion chamber rises into the gas vents at the edge of the reactor. It transports sludge particles to the water surface, creating a scum layer.

Why do septic tanks need to be pumped?

To prevent your septic system from failing, it should be pumped out before the solids accumulate to the extent that they start to flow out of the tank with the effluent to the drain field. If the layer of sludge is greater than a third of the tank’s volume, it is time to have the tank pumped.

How often does a 1000 gallon septic tank need to be pumped?

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.

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 Deep Should WePutthe Septic Tank at Original Installation?

Septic tanks may be built almost anywhere in the soil, regardless of its depth. When operating in a freezing climate, even in uninhabited homes, it is unlikely that the septic tank serving an occupied home or even an unoccupied one will freeze. This is due in part to latent heat received by the septic tank’s bottom from earth, in part to heat generated by bacteria in the septic tank, and in part to warm wastewater entering from a building served by the septic system, and in part to warm wastewater entering from the building served by the septic system.

You’ll kill the bacteria, damage the drainfield, and taint the surrounding ecosystem as a result of this.

Factors Determining Septic Tank Depth

The following are the primary elements that influence the actual depth at which a septic tank is likely to be buried (and, consequently, the depth to which you may have to dig to locate the septic tank) at a specific site:

• The depth to which the lowest sewage line departs the structure that the septic tank serves is referred to as the sewer line depth. Given that we often rely on gravity to transport sewage from a building to a septic tank, the tank will be lower than the waste line that exits the building that it serves. a spot where the contractor discovered site characteristics suited for burying a septic tank because of its form, rocks, and impediments If a location has bedrock or huge rocks that are near to the surface, the tank may be relocated
• The greater the distance between the tank and the structure, and the greater the depth of the tank if the system relies on gravity to carry sewage, the deeper the tank will be. We don’t place septic tanks any deeper than they need to be since we are normally transporting effluent from the septic tank to the drainfield by gravity as well as by pumping it out. Plumbers often build sewage lines to slope down from the inlet to the outlet at a rate of 1/8″ per foot to 1/4″ per foot of linear run of the waste pipe, depending on the kind of waste pipe. In order to avoid septic drainfield burial at an excessive depth, we must ensure that there is sufficient air in the soil, since the absence of oxygen deep in the soil will inhibit certain desired bacterial action (the aerobic bacteria) that is required to break down and process sewage. It is certainly possible to locate and position the septic tank anywhere, including uphill from the building, if a sewer ejector pump or grinder pump system is utilized to transport sewage from a structure to an underground storage tank. If a sewage effluent pump is used to transport septic effluent from the septic tank to the drainfield, we may, of course, locate the tank “downhill” from the drainfield as well
• But, if a sewage effluent pump is not utilized, we cannot. Growing grass: If the septic tank is just 2 or 3 inches below the surface of the earth, you might as well have left the top of the tank visible, because grass will not grow in such thin soil as you would expect. Adding 6″ to 12″ of backfill may be sufficient to allow grass to grow over the septic system
• However, this is a purely aesthetic issue and does not affect the system’s functionality. See SEPTIC SYSTEMS, OVERHAULED PLANTS
• Recommendations from the manufacturer: Some modern septic treatment system designs need the use of a skilled system operator to perform highly specified inspection and maintenance intervals. According to the information provided atBAT MEDIA SEPTIC PLANTS, BAT septic systems (biologically accelerated treatment) are maintained or examined at 6-month intervals, among other things. According to the maker of that technology (Jet Inc.), it is extremely critical that the finishing grade slope away from the facility when completed. In addition, the grade must be at least 1″ below the bottom of the access covers to be considered. (Jet retired in 2016)

A service riser should be put in deep septic tanks to provide access to the tank. Plungers are large-diameter “wells” that are installed over the entrance and/or outlet ports of a septic tank in order to provide simple access for tank pumping, inspection, and baffle repair. Plungers are also used for septic tank pumping, inspection, and baffle repair. If the septic tank is sunk more than a few inches below the surface of the earth, good practice calls for the installation of a septic riser, which is a high diameter pipe that allows for easy access to the septic tank for inspection and cleaning.

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 is treated by microbes that live on or near the soil.

Drip Distribution System

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

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

Aerobic Treatment Unit

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

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

Mound Systems

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

Recirculating Sand Filter System

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

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

Evapotranspiration System

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

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

Constructed Wetland System

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

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

Cluster / Community System

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

How Your Septic System Works

Underground wastewater treatment facilities, known as septic systems, are often employed in rural regions where there are no centralized sewage lines. They clean wastewater from residential plumbing, such as that produced by bathrooms, kitchen drains, and laundry, by combining natural processes with well-established technology. A conventional septic system is comprised of two components: a septic tank and a drainfield, often known as a soil absorption field. It is the septic tank’s job to decompose organic matter and to remove floatable stuff (such as oils and grease) and solids from wastewater.

Alternate treatment systems rely on pumps or gravity to assist septic tank effluent in trickling through a variety of media such as sand, organic matter (e.g., peat and sawdust), constructed wetlands, or other media to remove or neutralize pollutants such as pathogens that cause disease, nitrogen, phosphorus, and other contaminants.

Specifically, this is how a typical conventional septic system works:

1. All of the water that leaves your home drains down a single main drainage pipe and into a septic tank. An underground, water-tight container, often composed of concrete, fiberglass, or polyethylene, serves as a septic system’s holding tank. Its function is to retain wastewater for a long enough period of time to allow particles to sink to the bottom and form sludge, while oil and grease float to the surface and produce scum. Sludge and scum are prevented from exiting the tank and moving into the drainfield region by compartments and a T-shaped outlet. After that, the liquid wastewater (effluent) exits the tank and flows into the drainfield. The drainfield is a shallow, covered hole dug in unsaturated soil that serves as a drainage system. Porous surfaces are used to release pretreated wastewater because they allow the wastewater to pass through the soil and into the groundwater. In the process of percolating through the soil, wastewater is accepted, treated, and dispersed by the soil, finally discharging into groundwater. Finally, if the drainfield becomes overburdened with too much liquid, it can flood, causing sewage to flow to the ground surface or resulting in toilet backups and sink backups. Finally, wastewater percolates into the soil, where it is naturally removed of harmful coliform bacteria, viruses, and nutrients. Coliform bacteria are a kind of bacteria that may be found in the intestines of humans and other warm-blooded animals, with humans being the most common host. As a result of human fecal contamination, it is a sign of this.

The Guadalupe-Blanco River Authority has built an animated, interactive model of how a residential septic system works, which you can view here.

Do you have a septic system?

It’s possible that you’re already aware that you have a septic system. If you are not sure, here are some tell-tale symptoms that you most likely are:

• You make use of well water. In your home, the water pipe that brings water into the house does not have a meter. In the case of a water bill or a property tax bill, you will see “$0.00 Sewer Amount Charged.” It is possible that your neighbors have a septic system

How to find your septic system

You can locate your septic system once you have confirmed that you have one by following these steps:

• Taking a look at the “as constructed” drawing of your house
• Making a visual inspection of your yard for lids and manhole covers
• Getting in touch with a septic system service provider for assistance in locating it

Failure symptoms: Mind the signs!

A bad odor is not necessarily the first indicator of a septic system that is failing to work properly.

Any of the following signs should prompt you to seek expert assistance:

• Water backing up into the drains of homes and businesses
• It is especially noticeable in dry weather that the drainfield grass is bright green and spongy. The presence of standing water or muddy soil near your septic system or in your basement
• A strong stench emanating from the area surrounding the septic tank and drainfield

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.

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

Septic systems used in single-family homes and small businesses account for the vast majority of all installations in the United States. A high number of individuals in a single area is not often served by traditional systems, which are not normally constructed to do so. The following are the components of a typical system. Drainage system sewage system sewage disposal system For example, a gravel-filled drain field or an underground wastewater infiltration system A strong geofabric layer that protects the clean drain field from additional possible pollutants is essential.

Water (or effluent) is routed from the septic tank to the drain field in this location.

Once the wastewater has been filtered via the clean drain field, it continues to flow further into the soil, where it is constantly cleaned by naturally existing bacteria as it gently trickles its way through the soil layer and toward the groundwater supply.

Inconvenient to install in tiny lots such as those found in urban areas.

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.

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

In contrast to conventional septic systems, the Evapotranspiration System’s drain field is contained within a closed, waterproof field that is filled with layers of gravel and sand to keep out the elements. Water slowly evaporates once it has passed through the septic tank and into the waterproof drain field. This system, in contrast to conventional septic systems, ensures that no effluent seeps into the soil. When compared to other options, the ease of installation, maintenance, and use is superior.

Benefits: A high degree of simplicity in usage, as well as minimal levels of installation and maintenance Cons: Excessive humidity or rains will interfere with the correct operation of the evapotranspiration system

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.

What Is A Septic Tank & How Does It Work?

Many individuals are unfamiliar with the notion of septic tanks. However, for those households that do make use of one, they are extremely important. If you’ve always lived in a property that has been linked to the city’s main sewage system, it’s likely that you haven’t ever heard of a septic tank, let alone understood what it is. What a septic tank is and how it functions will be discussed in detail in this blog.

What Is A Septic Tank?

Essentially, a septic tank is an underwater sedimentation tank that is used to cleanse waste water through the processes of biological breakdown and drainage. A septic tank is a wastewater treatment system that uses natural processes and time-tested technology to treat wastewater from residential plumbing, such as that produced by bathrooms, kitchen drains, and laundry. The design of a septic tank system is pretty straightforward. It is a waterproof container (usually rectangular or spherical) that is buried underground and made of fiber glass, plastic, or concrete.

• septic tank systems are classified as “simple on-site sewage facilities” (OSSFs) since they only provide rudimentary sewage treatment.
• Excreta and wastewater are collected in a large underground tank, and they are mostly utilized in rural regions to keep the environment clean.
• It is common for them to be comprised of two chambers or compartments, as well as a tank that collects wastewater via an entrance pipe.
• This will be maintained and managed by a local water business.
• There are, however, certain additional measures that must be observed.
• Homeowners who have a septic tank have an added responsibility to ensure that their tank does not have an adverse influence on the surrounding environment.

In some cases, if a drain field becomes overwhelmed with too much liquid, it might flood, which can result in sewage flowing to the ground surface or creating backups in toilets and sinks.

How Does A Septic Tank Work?

It is the job of a septic tank to break down organic waste and separate it from floatable substances (such as oils and fats) and solids in wastewater. Two pipelines will be installed to connect a septic tank (for inlet and outlet). Septic tanks are equipped with intake pipes, which are used to convey water waste from homes and collect it in the tank. It is stored here for a sufficient amount of time to allow the solid and liquid waste to be separated from one another. The second pipe is the pipe that goes out.

• This pipe transports pre-processed effluent from the septic tank and disperses it evenly over the land and watercourses of the area.
• (as seen in the illustration above) The top layer is comprised of oils and grease, and it floats above the rest of the waste.
• Wastewater and waste particles are found in the intermediate layer of the wastewater system.
• Bacteria in the tank try their best to break down the solid waste, which then allows liquids to separate and drain away more readily from the tank.
• This is one of the reasons why a septic tank is considered to be a rudimentary type of sewage disposal.

The Step-by-step Process of How a Septic Tank Works

1. Water from your kitchen, bathroom, and other areas drains into a single main drainage pipe that leads to your septic tank. The septic tank, which is located underground, begins the process of storing waste water. It must maintain this condition for an extended period of time so that particles settle to the bottom and oil and grease float to the top. Following the completion of this operation, the liquid wastewater (effluent) will be allowed to escape the tank and enter the drainfield. This effluent is dumped into the environment through pipelines onto porous materials. The soil is able to filter wastewater through the use of these. In the process of percolating through the soil, wastewater is accepted, treated, and dispersed by the soil
2. The wastewater eventually discharges into groundwater. Last but not least, the wastewater percolates into the soil, where it is naturally removed from the environment by coliform bacteria, viruses and nutrients.

Septic System Basics

When a household isn’t connected to a public sewage system, it normally relies on septic systems to treat and dispose of wastewater. Sewage treatment systems require a substantial financial commitment. The correct maintenance and upkeep of a well-designed, installed, and maintained system will provide years of dependable and low-cost service. The failure of a system can become a source of pollution and public health concern, resulting in property damage, ground and surfacewater pollution (such as contamination of well water used by you and your neighbors), and the spread of disease.

Aside from that, if you are planning to sell your property, your septic system has to be in good functioning order.

Septic systems are available in a variety of configurations to accommodate a wide range of soil and site conditions.

Understanding the major components of a typical (gravity-fed) septic system, as well as how to maintain it working properly and at the lowest possible cost, can help you make the best decision possible. A conventional septic tank system is composed of three major components:

• This is known as the Septic Tank. In order to remove particles from wastewater, store and partially decompose as much solid material as possible, while allowing the liquid (or effluent) to flow to the drainfield, a septic tank must be installed. more
• The Drainage System After the particles have settled in the septic tank, the liquid wastewater (also known as effluent) is released to the drainfield, which is also known as an absorption or leach field, or both. more
• The Soil is a very important factor. The soil under the drainfield is responsible for the ultimate treatment and disposal of the septic tank effluent once it has been treated. Following the passage of wastewater into the soil, organisms in the soil remediate the effluent before it percolates downward and outward, eventually entering ground or surface water sources. A drainfield’s efficacy is also affected by the kind of soil
• For example, clay soils may be too tight to allow much wastewater to run through, while gravelly soil may be too coarse to give much treatment.

Homeowners and residents have a significant impact on the functioning of their septic systems. Overloading the system with more water than it is capable of handling might result in system failure. A septic system can also be damaged by the improper disposal of chemicals or excess organic waste, such as that produced by a trash disposal. The following maintenance suggestions might assist you in ensuring that your system provides long-term, effective treatment of domestic waste.

Inspect and Pump Frequently

The most critical step in keeping your septic tank in good working order is to eliminate sludge and scum build-up before it may flow into the drainfield. The frequency with which your tank has to be pumped is determined by the size of the tank, the number of people in your family, the quantity of water utilized, and the amount of solids (from humans, garbage disposal, and any other waste) that enter the tank’s drainage system. Tanks should be pumped out on average every 3 to 5 years, depending on usage.

Use Water Efficiently

System failure is frequently caused by an excessive amount of water. The soil beneath the septic system must be able to absorb all of the water that is used in the residence. Too much water from the washing machine, dishwasher, toilets, bathtubs, and showers may not provide enough time for sludge and scum to separate properly in the drain. The less water that is consumed, the less water that enters the septic system, reducing the likelihood of system failure. For further information on water conservation, visit:

Minimize Solid Waste Disposal

What you flush down the toilet can have a significant influence on the performance of your septic system. Many things do not breakdown properly, and as a result, they accumulate in your septic tank. If you have the option of disposing of it in another manner, do so rather than introducing it into your system.

Keep Chemicals Out of Your System

Protect your septic system against home chemicals such as caustic drain openers, paint and pesticides. Also avoid flushing down the toilet with chemicals such as brake fluid, gasoline, and motor oil. The improper dumping of dangerous substances down the drain is damaging to the environment, as well as the bacteria that are necessary for the breakdown of wastes in a septic system, and should be avoided.

Septic System Additives

It is not essential to add a stimulant or an enhancer to a septic tank in order to assist it in functioning or “to restore bacterial equilibrium.” The naturally occurring bacteria required for the proper operation of the septic system are already present in human excrement. Septic systems, like automobiles, are designed to offer long-term, effective treatment of residential waste if they are properly run and maintained on a regular basis. The majority of systems that fail prematurely, on the other hand, are the result of poor maintenance.

If you see any of the indicators listed below, or if you have reason to believe your septic system is experiencing issues, call a trained septic technician immediately. In the event that your septic system fails, call Thurston County Environmental Health at 360-867-2673 for assistance.

• Odors, surface sewage, moist areas, or a dense growth of plants in the drainfield region are all possible problems. Backups from the plumbing or septic tank (which are often a dark liquid with a foul odor)
• Fixtures that take a long time to drain
• The plumbing system is making gurgling sounds. Your drainfield may be failing if you have a well and tests reveal the presence of coliform (bacteria) or nitrates in the water from it. Even in the midst of a drought, the drainfield is covered with lush green grass.

Septic Solutions – Installation

There are four basic types of septic systems to consider. The availability of all four types may not be available to every homeowner due to the fact that municipal rules may prohibit the installation of traditional systems in areas where soil absorbtion or drainfield space is restricted. Furthermore, each has its own set of benefits and drawbacks to consider. The majority of municipalities need an engineer to do a site review. The outcomes of this examination will decide the alternatives available to the homeowners.

Installation prices also differ depending on the system type, so there is a lot to consider when deciding which system is ideal for you.

Conventional Systems

Traditional septic systems may be divided into two categories: those that employ gravel in the drainfield and those that use some sort of chamber system. The earlier stylegravelled system, as the name implies, comprises a layer of gravel in the drainfield. In the course of the building, a drainfield ditch is dug that is 1 to 3 feet below ground level. Its length is decided by the amount of effluent 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.

• In order to prevent backfill dirt from filtering between the rocks and decreasing the field’s ability to absorb water, more gravel is poured around and over the pipe.
• Despite the fact that some waste is treated in septic tanks by bacteria that live within the tank, the majority of waste treatment happens when wastewater discharged from the tank enters the drainfield and is filtered through the gravel and soil below.
• These organisms grow and produce a layer known as a biomat, which sits on top of the soil layer and protects it.
• The presence of these organisms helps to maintain the biomat from getting so thick that it prevents wastewater from reaching the soil below while the drainfield is in equilibrium.
• Because gravel is used to filter the effluent, it instantly reduces the capacity of the effluent to reach soil, which is where the majority of the filtation takes place.
• 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.
• This can happen when the water table rises over the drain pipe, essentially cutting off the drainfield’s capacity to release water completely.

After that, there’s the chance of drainfield overflow, which can occur 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.

Some of the disadvantages of gravelled systems are alleviated by gravelless conventional systems.

Typically, these chambers are made of molded high-density plastic and are available in lengths ranging from 10′ to 12′ feet.

Because we have discovered that the Infiltrator chamber system is the most successful when used in North Texas soils, Septic Solutions of Texas solely employs the Infiltrator chamber system.

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.

This is particularly effective in areas where the water table might rise near to the surface, as well as in situations where there is a brief rush in demand as a consequence of additional visitors.

Obviously, shock loading for extended periods of time will 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. Particularly relevant in situations where geography dictates that the drainfield be positioned up-hill from the septic tanks or where there is uneven terrain that would otherwise prevent the installation of a traditional 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.

1. The drainfield for an LPD application is made up of tiny perforated pipes laid in shallow, gravel-lined trenches that range in depth from 10″ to 18″ and in width from 12″ to 18″.
2. After then, the field is allowed to drain.
3. Shallow placement also encourages evapo-transpiration, which is the process by which evaporation and grass and other shallow-rooted vegetation serve to remove waste.
4. Alarms will be activated if there is a significant increase in flow.
5. Whenever a drainfield is not placed on a slope, the system will be constructed in such a manner that effluent does not exit the pumping chamber after the pump has been switched off.
6. Furthermore, because of the employment of a low-pressure pump, the whole drainfield will be utilized in a consistent manner.
7. However, there are several disadvantages to LPDs, including the possibility of root penetration and the blockage of drain holes by particles that leave the pumping chamber.

Finally, LPDs must be serviced on a regular basis. Electricity, a pump, and a smaller drainfield all raise the likelihood of system failure. As a result, most regulatory agencies now mandate septic system inspections by qualified septic specialists on a yearly or semi-annual basis.

Evapotranspiration Systems

The use of Evapotraspiration Systems (ETs) is often only practicable in arid and semi-arid environments. To put it simply, we are interested in climates where evaporation surpasses rainfall by at least 24 inches per year. The EP system is based on the natural evaporation of wastewater via a sand barrier, as well as the simultaneous transpiration of water through the leaves of plants and grasses grown above the drainfield, to remove pollutants. In contrast to the methods mentioned above, an ET system consists of a trench lined with an impervious barrier that drains to a collection basin below ground.

1. Above the gravel is a layer of sand that is raised above the level of the surrounding ground.
2. Naturally, this sort of system performs best during the spring, summer, and fall seasons, when heat and sunlight combine to deliver the most effective wastewater treatment.
3. Applications in places with short soil depths and impermeable rock or hardpanlayers beneath the surface are recommended.
4. Additionally, after the system has been in operation for an extended length of time, there is the possibility of salt accumulation near the surface.
5. This is essentially the same system as an ET system, with the difference that the drainfield is not enclosed in this configuration.
6. Generally speaking, wastewater must be able to flow through at least 2 to 4 feet of unsaturated soil before reaching the ground water table in order to be effective.
7. In North Texas, most permitting authorities demand the construction of two fields, with the owner physically switching the wastewater flow between the fields once a month, as well as the building of two fields.

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. As a result, your aerobic system closely resembles many of the stages and operations carried out by a municipal solid waste treatment facility. Aerobic systems and septic systems are similar in that they both treat wastewater via the use of natural processes.

The increase in oxygen promotes the natural bacterial consumption of waste inside the system as a result of the increase in oxygen.

Upon completion of this process, the resultant discharge water is clean and pure enough to be released directly over the absorption field using sprinklers.

The installation of aerobic systems is currently mandated by many regulatory authorities, including those in North Texas, for both new house construction and the replacement of failing conventional, LPD, and Evapotranspiration systems.

A low-cost maintenance contract will lessen the need for intervention and care on the part of the homeowner.

There is less solid waste entering the aerobic chamber as a result of this method.

Following that, the wastewater enters the aerobic chamber, where air is compressed and pumped into the wastewater in order to promote the development of good bacteria that eat the particles in the wastewater.

After that, the treated water is pumped into a pumping chamber, where it undergoes a last treatment with unstabilized chlorine before being discharged.

The pump will discharge the water into the absorption field when a float valve within the pump chamber detects the presence of water.

In most cases, aerobic systems are not significantly more expensive to build and operate than traditional septic systems.

Typically, they are less expensive to build than LPDs or Evapotranspiration systems since they do not require the use of sand and/or gravel to prepare a drainfield prior to installation.

This maintenance contract will provide you with the assurance that your plant will operate in accordance with specifications at all times.

If your maintenance contract expires before the end of this period, you will be required to either renew it or seek a new one from another waste water treatment specialist.
