- Use 1 gallon of product via the toilet, sink or drain closest to the septic tank outlet. Next Apply 1 gallon of product into the drain field soil directly. After 1 week add another 1 gallon.. Flush freely with water to distribute it throughout the septic system drain field.
What kind of soil is needed for septic system?
The soils best suited for wastewater treatment are mixtures of sand, silt, and clays referred to as loamy soils. The architecture of the soil is also important in estimating its permeability. The soil particles stick together to form structural units.
What is the best thing to put in your septic tank?
Biological Additives. Biological additives, like bacteria and extracellular enzymes, are the only acceptable septic tank treatment for promoting a healthy, natural bacterial ecosystem, maintaining an effective drain field, and protecting the health of the local groundwater.
What type of soil is best for treating effluent from a septic tank system?
In general, you want sandy soil that is not too coarse, well-drained soil, and naturally undisturbed soils to absorb the effluent. When the soil is too coarse, wastewater passes too quickly to receive sufficient treatment.
How do you treat a septic field?
Do’s and Don’ts when maintaining your septic system
- Regularly inspect and maintain your septic system.
- Pump your septic tank as needed.
- Keep your septic tank lids closed and secured.
- Be water-wise.
- Direct water from land and roof drains away from the drainfield.
- Landscape with love.
- Keep septic tank lids easily accessible.
What is the best soil for a leach field?
Clay soil is very compact and does not give room for the effluent to seep through. Clay soils can, therefore, result in backups in the leach field. The best soil for a septic system is a soil that lies somewhere in between gravel and clay. It is neither too dense and neither is it too loose.
What can break down poop in septic tank?
Yeast helps actively breaks down waste solids when added to your septic system. Flush ½ cup of dry baking yeast down the toilet, the first time. Add ¼ cup of instant yeast every 4 months, after the initial addition.
What will baking soda do to a septic system?
Will baking soda hurt a septic system? Baking soda and other common household solutions such as vinegar are not harmful to your septic system. Harsh chemicals such as bleach and ammonia can disrupt the good bacteria in your septic tank and should not be used as part of a septic treatment.
How do you dissolve sludge in a septic tank?
How to Reduce Sludge in a Septic Tank Without Pumping
- Install an aeration system with diffused air in your septic tank.
- Break up any compacted sludge.
- Add a bio-activator or microbe blend.
- Maintain the aeration system.
- Add additional Microbes as required.
Will red clay soil perc?
Clay soils have notoriously slow percolation speeds of 0.1 inch or less per hour. These soils easily become waterlogged, and plant roots can suffocate as a result.
Is sand good for a septic system?
Best Soils for Septic Systems and Drainfields The best soils and soil types for drain fields are: Sandy Soils. Grounds with Low Clay Content. Soils like clay and silt absorb water readily, taking up more space and clogging the system.
How do you tell if your septic tank is full?
How to tell your septic tank is full and needs emptying
- Pooling water.
- Slow drains.
- An overly healthy lawn.
- Sewer backup.
- Gurgling Pipes.
- Trouble Flushing.
Are long showers bad for septic systems?
Washing frequent, small loads of laundry or taking exceptionally long showers every day is all it takes to overload your septic system with too much water. The primary treatment tank needs time to break up solids before partly-treated water can enter the drain field.
How do you fix a saturated leach field?
Additional ways to help keep the soil in your drain field from becoming over-saturated include:
- Avoid using too many water fixtures in the home at once.
- Ensure all home gutter downspouts are directed away from the drain field.
- Don’t point lawn sprinklers toward drain field.
Septic Tank: Soil Treatment System
Homes that are not connected to a municipal sewer system must treat and distribute wastewater on their own property. The use of onsite systems such as septic tanks with soil treatment systems (also known as leach fields) is rather widespread. The septic tank eliminates the majority of the settable and floatable particles from wastewater, preventing the soil from becoming clogged. The earth beneath the pipes, which are buried in the yard, filters out pollutants and pathogens, allowing the wastewater to be treated before it is discharged into groundwater and surface water.
Bedrock, sand, and gravel, hard and compacted layers, and water levels are all examples of limiting layers.
Therefore, a soil remediation system is not appropriate for every rural property.
A typical soil treatment system is seen in Figure 2.
- The wastewater soaks into the soil at the trench’s bottom, where the soil and soil microorganisms remove the toxins and disease-causing organisms that have accumulated.
- Based on soil and site circumstances, the length of a system for a three-bedroom house can reach 138 feet in some cases.
- Systems are also separated into two equal portions, each of which has a diversion mechanism that alternates the flow of waste.
- In the event that the system is destroyed or the soil is excessively compacted after construction, a replacement area is also necessary to allow for the installation of a new system.
- To create a gap in the trench bottom for wastewater to exit through a perforated pipe, a layer of gravel or a chamber is put on top of the natural soil at the bottom of the trench.
- The vertical separation distance refers to the depth of soil beneath the trench that separates the two sides of the trench.
- Installers of soil treatment systems will take care not to compress the soil during the construction of the system.
- For detailed instructions on how to design and build a system, see Ohio State University Extension Bulletin 939 (available in PDF format).
setll.osu.edu. As with any other domestic sewage system, the homeowner is responsible for keeping the system in good working order to ensure trouble-free operation. The homeowner should do the following:
- The septic tank should be pumped every one to five years
- Water should be used sparingly and water-saving measures should be installed in the residence
- Soil should never be compacted by paving, building, or parking automobiles
- By avoiding growing trees or bushes near the treatment system, you may avoid blocking pipes with root growth.
How Soil Impacts your Septic System – Septic Maxx
The septic tank should be pumped every one to five years; water should be used sparingly and water-saving measures should be installed in the residence; soil should never be compacted by paving, building, or parking automobiles; and By avoiding growing trees or bushes near the treatment system, you may avoid blocking pipes with roots.
The Journey of Effluent
The water that has been running after you turn off the shower or sink or flush the toilet continues to flow. If you use a septic system for your sewer treatment, this water will first pass through the septic tank, where it will go through a process that separates heavy particles from lighter items such as oils and grease before exiting the system. Heavier solids sink to the bottom of the tank and accumulate to produce a sludge layer, while lighter materials float to the top of the tank and accumulate to form a scum layer.
When the effluent leaves the treatment plant, it goes to the distribution box, where it flows via a series of pipelines until arriving to the drainfield.
Soil Beneath the Drain Field
The soil underneath your drainfield serves as the final stage in the treatment of the wastewater that has traveled through your septic system and into the ground. The primary function of soil is to act as a natural filter for water and other substances. Soil is made of 50 percent solid elements and 50 percent pore space, according to the International Soil Association. Minerals and rotting plant and animal remnants, as well as organic stuff, make up the solid components of the structure. In order to determine how successfully the soil filters incoming wastewater, the texture of the soil is critical.
It is the proportion of these three particles in the soil that determines how well the soil is able to store water and finally enable it to access the ground surface.
Physical Water Treatment
When the effluent from your septic system passes through your drainfield, the soil beneath it serves as the final stage in the process of treatment. Essentially, the role of soil as a natural filter is its most important function. Pore space and solid materials make about 50 percent of the total volume of soil in an area of 100 acres. Minerals and decomposed plant and animal remnants, as well as organic stuff, make up the solid components of the composition. In order to determine how successfully the soil filters incoming wastewater, the texture of the soil must be considered.
What matters is the ratio of these three particles, which determines how well the soil can hold water and finally enable it to seep into the earth.
Furthermore, soil includes millions of tiny creatures that feed on the organic stuff contained in the effluent in addition to physically providing a surface for it to flow over.
Biological Water Treatment
The soil has a diverse range of bacteria that are dependent on the organic material in the wastewater for their survival. The bacteria, algae, protozoa, fungus, rotifers, and nematodes found in a conventional wastewater treatment system are all harmful to the system’s operation. In wastewater, aerobic bacteria are the most effective in degrading the compounds that are present. The survival of this species of bacterium is dependent on the presence of oxygen. Additionally, anaerobic bacteria can be discovered in your sewage system, namely in your septic tank.
This is why soil that has been oversaturated with water is not a suitable filter, since it prevents oxygen from being absorbed, enabling anaerobic bacteria to flourish.

Onsite Wastewater Treatment Systems: Septic Tank/Soil Absorption Field
There are several microorganisms in soil that are dependent on the organic material in wastewater for their survival. The bacteria, algae, protozoa, fungus, rotifers, and nematodes found in a conventional wastewater treatment system are all harmful to human health. Chemical breakdown in wastewater is accomplished most efficiently by aerobic microorganisms. The survival of this species of bacterium is dependent on oxygen. Your septic system, namely your septic tank, contains anaerobic bacteria as well as aerobic bacteria.
Soil that has been saturated with water does not function well as a filter because it prevents oxygen from reaching the soil, allowing anaerobic bacteria to proliferate and flourish.

- Concrete septic tanks are the most prevalent
- Fiberglass tanks, which are becoming more popular because they are easier to transport to “hard-to-reach” areas
- And polyethylene/plastic tanks, which are available in a variety of sizes and designs. These tanks, like fiberglass tanks, are lightweight, one-piece constructions that can be transported to “hard-to-reach” sites.
All tanks must be completely waterproof in order to prevent rainfall from entering the system. Water entering the system has the potential to saturate the soil absorption field, resulting in the system malfunctioning. The waste water from the septic tank is discharged via the tank’s outflow and into the soil absorption area, where it is absorbed. When it comes to outlets, the most frequent configuration is a tee fitting attached to the pipe leading to the soil absorption field. An effluent filter, on the other hand, can be installed in the outflow tee to provide extra filtering of the wastewater.
Soil absorption field
The soil absorption field is responsible for the ultimate treatment and dispersion of the wastewater produced. Perforated pipes are surrounded with media such as gravel and chipped tires, which are then covered with geotextile fabric and loamy soil to form a traditional system. This method depends mainly on the soil to treat wastewater, where microorganisms assist in the removal of organic debris, sediments, and nutrients that have been left in the water after it has been treated. As effluent continues to flow into the soil, bacteria from a biological mat consume the components of the wastewater as it passes through the soil.
The water must go through unsaturated soil in order for bacteria in the soil and in the mat to be able to feed on the waste and nutrients in the effluent, which they cannot do otherwise.
When used appropriately, the septic tank and soil absorption system provide excellent performance. This method lowers two ratios that are often used to quantify pollution: biochemical oxygen demand, which is reduced by more than 65 percent, and total suspended solids, which is reduced by more than 70% Oil and grease are generally decreased by 70 to 80 percent throughout the processing process. The use of a septic tank to pretreat sewage also increases the effectiveness of various secondary treatment methods.
In order for a septic tank to function well, it must have the correct size and construction, as well as having a watertight design and a sturdy structural design. Capacity of the tank: The size of the septic tank you require is determined by the number of bedrooms in the home, the number of people who live in the home, the square footage of the property, and whether or not water-saving devices are installed. For example, a three-bedroom house with four occupants would need a 1,000-gallon water storage tank (see Table 1).
- All of these factors influence the effectiveness of the tank as well as the quantity of sludge it retains.
- As more particles accumulate in the tank, the water level in the tank grows shallower, necessitating a slower discharge rate in order to give the sludge and scum more time to separate from one another.
- It is necessary to install a riser on the openings of a septic tank if it is sunk more than 12 inches below the soil level.
- In most cases, the riser may be extended all the way to the ground surface and covered by a sturdy lid.
- Texture of the soil: Sand, silt, and clay are the three different types of soil textures.
- Sand transports water more quickly than silt, which transfers water more quickly than clay.
- Sandy soils are classified as soil type I, whereas clay soils are classified as soil type IV.
In addition to the hydraulic loading, which is the quantity of effluent applied per square foot of trench surface, there is another factor to consider during the design process: Given that water filters through clay soils more slowly than through sand or silt, the hydraulic loading rate for clay is lower than for silt, and the hydraulic loading rate for silt is lower than for sand.
The magnitude of the absorption field: The amount of wastewater that enters the system on a daily basis also influences the size of the absorption field that is required. The wastewater flow rate should be divided by the hydraulic loading rate for the soil type where the field will be created.
How to keep it working
It is necessary to have your septic tank pumped on a regular basis in order to maintain your system operating smoothly. Sludge collects at the bottom of the septic tank as a result of the usage of the septic system. Because of the increasing amount of sludge in the tank, wastewater spends less time in the tank and solids are more likely to escape into the absorption area. If sludge collects for an excessive amount of time, there is no settling and the sewage is directed directly to the soil absorption region, with no treatment.
The frequency at which you must push it out is determined by the following factors:
- The capacity of the septic tank
- The quantity of wastewater flowing into the tank (which is proportional to the size of the household)
- And the amount of particles in the wastewater (which is proportional to the amount of solids in the wastewater if you use a garbage disposal)
When building a home with three bedrooms in Texas, a 1,000-gallon septic tank is required. If four people reside in the three-bedroom house, the tank should be emptied every 2.6 years, according to the manufacturer (see Table 2). A family of two living in a three-bedroom house will require the tank to be emptied every 5.9 years if the same approach is used. It is vital to understand that if you do not pump your tank, the soil absorption field will not immediately fail. The septic tank, on the other hand, is no longer safeguarding the soil absorption field from solids.
- Cleaning the effluent filter is another maintenance activity that must be performed on a regular basis in order to prevent the system from backing up.
- Soil absorption fields must be kept free of solids and rain to ensure their long-term effectiveness.
- Rainwater runoff from rooftops or concrete surfaces should be diverted away from the soil absorption field to avoid the field becoming overflowing with water.
- Planting cool-season grasses over the soil absorption field in the winter can aid in the removal of water from the soil and the maintenance of the system’s appropriate operation and performance.
- Make contact with the appropriate county office.

It is necessary to abandon a septic tank correctly if it is no longer in use (for example, due to a new connection to the municipal sewer, tank replacement during a system upgrade or repair, or other reasons). In this case, the term “ancient cesspool” includes “leaching pit,” “dry well,” “seepage pit,” “vault privy,” and “pit privy.” There must be a permanent prohibition on access to the system for future discharge. If necessary, the piping can be removed and the supply pipe can be filled with grout to do this. Depending on where you live, there may be unique restrictions for this activity that must be adhered to. It is suggested that the following methods be used in the absence of particular code requirements. The ultimate objective is to make the region around the old tank safe and free of any environmental or public health hazards that may have occurred there previously. A vacuum truck driven by a suitably certified expert who will properly dispose of the septage must first be used to thoroughly empty the tank of its contents, which must then be refilled with clean water. In order to cope with an empty tank, there are three basic methods to follow:
If the soil treatment and dispersal systems are removed, the contaminated materials must be handled in a safe manner such that no human contact is made with them. In addition to distribution media and soil or sand located within roughly 3 feet of the system bottom, contaminated materials also include distribution pipes, tank linings, and contaminated soil surrounding leaking tanks. Any soil that has been contaminated by sewage as a result of a surface collapse is considered contaminated material.
- Typically, the soil treatment area is kept in place; however, if it is removed, care must be made to ensure that humans do not come into touch with any contaminated materials.
- All separation lengths required for a septic system, including well and property line setbacks as well as your vertical separation distance from saturated soil or bedrock, must be met at the stockpile site prior to use.
- If there are any extra or harsher ordinance requirements, the appropriate local unit of government should be consulted.
- In order to properly dispose of contaminated pipe, geotextile fabric, or other materials, they must be dried and then disposed of in a mixed municipal solid waste dump.
- The pump tanks are abandoned in the same manner as the other tanks, as previously explained.
- The ancient floats, if they were made of mercury, must be handled as a hazardous substance.
- All of the wire should be removed; the conduit can be left buried, but it should be capped to prevent it from being exposed.

No Place to Go: Placing a New Soil Treatment System Over the Old
Clean sand should be incorporated into the native soil by dragging the backhoe bucket teeth or thoroughly cultivating to produce channels of clean sand that will allow water to flow through the compacted soil.

Repair+ Receive Notifications As a result, when dealing with tiny lots, it may be necessary to consider relocating a soil treatment area from its current position if the existing system is not compliant or is even surface. This is a high-risk circumstance that should only be considered when there are no other alternatives. The natural soil structure, which has grown over thousands of years and is maintained in its unique forms by organic matter, clays, and/or iron, is incomparably superior.
This does not rule out the possibility of improvements being successful, but they may be more involved and expensive, as well as necessitate more maintenance and monitoring requirements.
- Soil that has been disturbed: When the system was installed, the soil that had been disturbed by the old system was disturbed. Most of the time, the soil atop a STA has been compacted during construction or thereafter by the property owner. A groundwater mound, which has formed as a result of the high quantity of wastewater that has been applied to the region, may have formed, elevating the natural water table. Wet circumstances and groundwater mounding Regardless of mounding, the STA will be quite moist as a result of the wastewater application (70,000-plus gallons from a typical residence). Consequently, there are worries regarding spreading and compaction during future development in the vicinity. A considerable biomat will have formed after several years of receiving septic tank effluent by gravity distribution from the STA. If the system has been in place for a long period of time, this will be true. The formation of a thin layer of biomat will occur even if the pressure distribution is uneven. If this biomat is left in place, it has the potential to restrict water circulation.
Solutions that could be implemented
- Solutions that are possible
- Allow for the drying of the STA. This might take many weeks or months, depending on the time of year, the season, and the age of the system. Opening one end of the system and enabling the system to drain into a trenched-out area, where a pump truck can remove the effluent can help to expedite the process.
- Remove the damaged soil and biomat from the site. Despite the fact that this prevents the possibility of compaction and biomat, it frequently results in disturbance of the underlying natural soils. It is possible that over-excavation beneath the system will be required. It is necessary to proceed with caution when establishing the optimum elevation of the system in this case since just removing the impacted soil does not alter the soil-water conditions on the site. Backfilling the area with clean sand must be done before moving on (mound sand). The system can then be constructed and deployed at the altitudes that have been recommended. Excavate over a deeper underground system and construct the second STA above the ground surface level. For mound sites where the only viable space to install a new system is over an existing one, another alternative is to deposit 6 inches of clean sand over the prepared native soil before installing the new system. This activity can only take place when the earth is completely dry. Use backhoe bucket teeth or deep cultivating to incorporate clean sand into the native soil
- This will allow water to circulate freely through the compacted soil.
There are several drawbacks to each of the alternative options listed above. Make careful to check with the local permitting authority before proceeding. The system should be controlled by an operating permit, which would allow for the evaluation of its performance over time.

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.
Prior to discharging wastewater into the environment, several alternative systems are designed to evaporate or disinfect the effluent.
Specifically, this is how a typical conventional septic system works:
- 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
Soil Compaction: A Pressing Issue for Soil Treatment Areas
It is best to avoid placing a play area above a soil treatment system in this manner in order to minimize compaction of the soil underneath it.
Interested in Onsite Systems?
In order to reduce soil compaction, it is best not to build a play area on top of an underground drainage system like this.
- Due to the fact that wastewater requires oxygen to be broken down, a reduction in oxygen transmission to the soil treatment region might shorten the system’s life. Additionally, a reduction in pore space reduces the routes available for wastewater to travel through soil. As a result of the absence of pore space, drainage is compromised
- The microbial population suffers as a result of the lower oxygen levels
- And the lack of vegetative cover is necessary to preserve components, utilize water, and avoid erosion. In fact, compacted soil can make it nearly hard to keep plants alive because it obstructs the circulation of water, oxygen, nutrients, and roots through the pore spaces between soil particles. Root penetration and growth are made more difficult as a result, resulting in weak, shallow roots, poor plant growth, and a larger requirement for watering and fertilizer. In turn, soil compaction can result in greater expenditures for the homeowner in the form of water, fertilizer, and ultimately plant replacement. In addition, we do not want fertilizer or irrigation applied to a septic system’s drainage field.
Causes of compaction
- The use of heavy machinery on landscapes during construction, as well as continual traffic, such as the use of unpaved portions as roadways or parking lots, or the mowing of the same area repeatedly when the soil is wet, can induce or worsen compaction. Traffic – People, animals, and cattle walking over the region may induce compaction, and this problem will be exacerbated if the soil is moist or compacted. Do not place playground equipment, such as swing sets, near the soil treatment area. Motorbikes, bicycles, all-terrain vehicles, and snowmobiles are all permitted to use the sewage system as a trail. Moreover, in colder areas, this compaction increases the risk of frost formation.

- When work is taking place near the septic system, erect a temporary barrier to prevent vehicles from passing through the system. Put up barriers to keep vehicles from getting through
- When the soil is excessively damp, avoid working it (this includes mowing). Inform everyone on the property about the issues, and if the property is in a high-traffic location, consider putting up signs to draw attention to the situation.

Investigate Before You Invest
If you are considering purchasing a building lot for the construction of a new house, do your research beforehand. Depending on whether a public sewer system is accessible, you may be required to install a septic tank and soil treatment system (septic system) to treat and dispose of sewage from the residence you intend to construct on the property. If a septic system is required, the following actions should be taken before purchasing land:
- Determine the types of soils that exist on the property
- Investigate what sort of septic system, if any, will function properly on such soils. Inquire with your local health department about obtaining a septic system improvement permit (IP). Obtain an estimate for the cost of installing the type of septic system that you require. Find out what the system’s running needs are, as well as its maintenance expenses.
Identify the different types of soils on the property. Investigate what sort of septic system, if any, will function properly on such soils; Inquire with your local health agency about obtaining a septic system improvement permit (IP); To find out how much it will cost to install your particular type of septic system, contact a local contractor. Consult with a representative regarding the system’s operational needs and maintenance expenses.
- Whether or whether there are gullies, ravines, overly steep slopes, or other topographic challenges that would make the installation of a system problematic
- Is the area adjacent to a stream or river that has the potential to flood it
- The property appears to be muddy and marshy
- Does the site contain any wetlands that have been designated? Is it possible to obtain a map showing the extent of any designated wetlands on the property? Are there any rocky areas on the land? A septic tank system would be incompatible with bedrock because it would interfere with the installation and functioning of the system. The building lot should have adequate room for the house, septic system, and a water supply well (should one be required).
Your well, as well as all of your neighbors’ wells, should be at least 100 feet away from the septic system. In addition, there must be enough space to accommodate a “maintenance area,” which may be used in the event that the system requires extension or repair in the future. One acre of land with adequate soils and suitable terrain is typically considered to be the minimum required space. However, in areas where soil and site characteristics are less favorable, significantly bigger lots are typically required.
- To learn more about the soils in your region, contact your county Extension office or the local soil and water conservation district (if one exists).
- You may utilize this report to assist you in screening property parcels and concentrating your efforts on those lots that have the most ideal soil and site qualities, which will help you achieve your goals.
- It should not be used as a substitute for an on-site study of soil and ground conditions.
- A complete onsite examination must be carried out by the local health authorities to determine whether or not the property is suitable for a medical facility.
- It is important to remember, however, that unsuitable soils and acceptable soils can coexist on the same parcel of land.
- The standard septic system, which consists of a septic tank and a number of trenches that are sunk 2 to 3 feet deep, is installed on over half of the homesites in North Carolina that have septic systems.
- These systems are quite affordable; the average installation cost ranges from $650 to $2,000, depending on where in the state you reside.
Alternative septic systems include low-pressure pipe (LPP) systems, fill systems, and other systems that have been expressly built for a particular use.
It is also possible that fill systems will be prohibitively expensive and impossible to implement.
Although there are many soils that are ideal for alternative septic systems, there are others that are not.
Make an application for an improvement permit with your local health department.
Inquire as to whether the permission will have an impact on the number of bedrooms that may be created in the home, as well as the location of the house, driveway, or the presence or absence of a swimming pool.
Additionally, you may decide to condition your sale on the issue of a permit for an approved type of wastewater treatment system (sewage treatment plant).
For additional information on the types of septic systems that are currently in use in your region, contact your local health authority.
A guide to Land Suitability for Septic Tank and Soil Treatment Systems explains how sewage effluent is cleansed in soils and how to evaluate the suitability of soils on your property for a sewage treatment system.
When evaluating the acquisition of a building lot, other information such as subdivision and land use rules, zoning, deed limitations, construction setbacks and ordinances, and financial information should be considered.
Amazon.com: Septic Perc Septic System Drain Field Soil Treatment : Health & Household
Verified Purchase on May 4, 2016 in the United States of America When we first moved into this building, we had seepage from our leachfield and distribution box. The seepage in the leachfield was partially caused by the need for a new distribution box, which we installed; nonetheless, the seepage continued to exist. With this Septic Perc and the Mega Bio, we treated the septic system and were pleased with the results. We saw an improvement in the leachfield a couple of weeks after treatment was completed.
- Every year when we have our septic tank pumped, we receive great reports from the service firm stating that our septic tank and leachfield are in excellent condition!
- We will be eternally grateful!
- Purchase that has been verified Due to a buildup of bio-mat in the leech field in 2015, my system came to a grinding halt completely, rendering it unusable.
- We purchased a case and began treating our system.
- The thick, black bio-mat had been totally removed, and the pipe was now perfectly transparent.
- Due to the fact that Septic Seep was no longer in stock, I opted to experiment with the Septic Perc substitute.
- Septic Seep was a fantastic product, but Septic Perc is a disappointment.
They were undoubtedly under pressure from the Environmental Protection Agency to design a product that was more ecologically friendly than the Seep.
On December 17, 2019, a review was conducted in the United States.
I believe that the enzyme therapy may be good, but I do not believe that the liquid has any significant effect.
Purchase that has been verified As a layperson, it’s impossible to know much about this type of product, however I’ve been using Septic Perc for a few years now and it appears to be doing as stated.
On May 27, 2017, a review was conducted in the United States.
Time will tell whether or not this is true.
On May 12, 2015, a review was conducted in the United States.
Perhaps he became enraged because the septic perc did not function.
I purchased a 4-gallon container and put it onto a leach field, but the leach field was unable to absorb anything. There has been no change. I believe I lost 254 dollars. On August 15, 2015, a review was conducted in the United States.

What do germs, dirt, and gravity all have in common? Read on to find out. All of these environmental elements and natural processes contribute to the ability of your septic system to perform its waste processing and wastewater treatment functions. Untreated water that is discharged back into the water table can pollute your town if these measures are not taken. While we understand how to maintain the health of the bacteria in our septic tanks, and while gravity works on its own, what about our soil?
Other rules, including as setbacks, tank capacity, and lawn size, are all important considerations. Soil requirements and soil types may make or break your septic system installation. Not only that, but there are a number of elements that must be considered when determining if the soil in your yard is suitable for a septic system and drainfield.
Soil requirements and soil types, in addition to other criteria such as setback distances, tank capacity, and grass area, can make or break your septic system installation. Not only that, but there are a number of elements that must be considered when determining if the soil in your yard is suitable for a septic system and drainage field.
Are there any coarse or gritty soils present? Will the soils be able to absorb an excessive amount of water? Is it hefty or light in weight? The amount of sand, silt, and clay contained in the soil is determined by the texture of the soil. A high concentration of clay indicates that the soils are overly heavy. A ground that has too many heavy silts will be less permeable.
If so, what kind of texture does the soil have? The soils will they be able to hold in too much moisture. It’s either hefty or light, depending on your preference. The texture of the soil dictates the amount of sand, silt, and clay that is present in the soil. Overabundance of clay indicates that the soils are very heavy. A ground that has too many heavy silts is less permeable.
Are there any coarse or gritty soils here? Will the soils be able to absorb a significant amount of water? Is it a hefty or a light object? The amount of sand, silt, and clay in the soil is determined by the texture of the soil. The presence of excessive clay indicates that the soils are overly heavy. A ground with too many heavy silts will have decreased porosity.
How Do You Test Soil for Septic Systems?
The percolation test, also known as deep hole testing, is a type of test in which a deeply excavated hole is used to measure the amount of water that percolates through it. For the most part, the holes are around seven to ten feet deep and are located below the bottom of probable drainfield locations. In percolation testing, soil samples are collected and analyzed to determine the seasonal high water table height and how it relates to the depth of the soil above the water table. Two or more holes are dug, which are generally half a foot to a foot deep—the depth of an ordinary leach field.
After filling the bottom of the hole with clean gravel, fill the hole with water and note how rapidly the water drains. However, the lowest times per inch are often about 5 minutes, while the highest times per inch are typically over 30-45 minutes.

The percolation test, also known as deep hole testing, is a type of test in which a deeply excavated hole is used to measure the amount of water that has percolated through it. A typical hole is around seven to ten feet deep and located below the surface of prospective drainfield locations. Percolation testing needs two or more holes, which are generally half a foot to a foot deep—the depth of an ordinary leach field. Testers take soil samples and investigate the seasonal high water table height in relation to the depth of the soil above it.
After filling the bottom with clean gravel, fill the hole with water and note how rapidly the water drains.
- Sandy soils
- Soils with a low percentage of clay content
- Loamy Soils (soils that include a variety of particle sizes that allow for gaps and pores to develop)
- Soils that are either non-retentive or non-absorbent. Landscaping materials such as clay and silt rapidly absorb water, taking up additional area and clogging the system.
What is the optimal soil? Somewhere in the middle between gravel and clay.

Identify My Septic System

Traditional septic systems may be divided into two categories: those that employ gravel in the drain field and those that use some sort of chamber system. The older style graveled system, as the name implies, has a coating of gravel in the drain field to facilitate drainage. In the course of the building, a drain field ditch is dug that is 1 to 3 feet below ground level. Its length is decided by the amount of wastewater that will be discharged into the system from the house or rural office, as well as the soil’s ability to absorb water during the winter months.
- In order to prevent backfill soil from filtering between the rocks and reducing the field’s ability to absorb water, additional gravel is poured around and over the pipe.
- Despite the fact that some waste is treated in septic tanks by bacteria that live within the tank, the majority of waste is treated when wastewater released from the tank enters the drain field and is filtered via the gravel and dirt under the surface.
- These organisms grow and produce a layer known as a biomat, which sits on top of the soil layer and protects it.
- When the drain field is in balance, these organisms prevent the biomat from getting so thick that it prevents wastewater from passing through to the soil underneath the drain field.
- In the first place, the use of gravel instantly reduces the amount of wastewater that may reach the soil, which is where the majority of filtration takes place.
- 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 above the drain pipe, essentially cutting off the drain field’s capacity to release water and causing it to back up.
In addition, when there are more visitors in the house for extended periods of time, or when taps or toilets are left running for extended periods of time, there is the chance of a drain field overflow, which can develop.
Gravel-less conventional systems have the advantage of overcoming some of the disadvantages of graveled systems.
Typically, these chambers are made of molded high-density plastic and are available in lengths ranging from 4 to 5 feet.
When the system is put into service, waste water is transported via pipe from the septic tank to the chamber run, where it flows directly against the earth.
One significant advantage of the chambered system is its capacity to accommodate significantly greater volumes of water.
Shock loading over extended periods of time will, without a doubt, have a negative impact on the biomat since oxygen will not be accessible to parasites during these durations.
Low-Pressure Dose Systems
Low-pressure dosing systems (also known as low-pressure pipe systems) may be a viable option in situations when soil and topographical factors do not allow for the installation of a typical septic system, such as urban areas. This is especially true in cases where the geography necessitates the installation of a drain field uphill from the septic tanks or when there is uneven terrain that would otherwise impede the installation of an ordinary system. Low-Pressure Dose Systems (LPDs) are designed to function in the following ways: A pumping chamber is placed in addition to the typical septic tank, which is a type of holding tank.
- When using an LPD application, the drain field is made up of small perforated pipes that are placed in shallow, gravel-lined trenches that are 6 to 24 inches deep and 36 inches wide.
- After then, the field is allowed to drain.
- Low-lying placement also encourages evapo-transpiration, in which evaporation, as well as grass and other shallow-rooted plants, aid in the removal of wastewater from the soil.
- Alarms will be activated if there is a significant increase in flow.
- In addition to the previously noted topographical site benefits of LPDs, there is a considerable reduction in the amount of land area required by the absorption field when compared to traditional systems.
- Furthermore, narrow, shallow ditches help to mitigate some of the unavoidable soil compaction that occurs during the building of typical drain fields.
- The risk of wastewater accumulating in the trenches should also be considered.
- The inclusion of power, a pump, and a narrower drain field all raise the likelihood of system failure.
Aerobic Wastewater Treatment Systems
At this point, aerobic septic systems stand out as the only system that can be used in virtually all case where septic systems are needed. In essence, when you own an aerobic system, you are the owner of a miniature version of a municipal sewage treatment facility. In other words, your aerobic system closely resembles many of the stages and operations carried out by an urban waste treatment facility. Aerobic systems and septic systems are similar in that they both treat wastewater via the use of natural processes.
- The natural bacterial consumption of waste inside the system is increased as a result of the increase in oxygen.
- The way aerobic systems function is as follows: Pre-treatment tanks are used to catch grease, oils, toilet paper, and other solids and foreign items that are present in wastewater and effluent.
- Solids can clog the system and create difficulties if there are too many of them.
- Following that, the treated water is sent to a pumping chamber, where it undergoes a final disinfection treatment.
- Water is then pumped into the field and distributed through a drainfield.
- Systems are specifically constructed with alarms and control boxes to ensure that they are always in correct working order at any given moment.
This maintenance contract will ensure that your plant operates in accordance with specifications at all times, regardless of the weather.
Under the majority of circumstances, conventional septic systems are sufficient for treating and disposing of domestic wastewater. However, when soil conditions or the surrounding region are not suitable for handling the volume of effluent generated by a standard septic system, an alternate system, such as a drip system, may be the best solution. A typical system relies on gravity to carry wastewater, and as a result, the effluent is not distributed uniformly over the drain field as effectively as it may be.
It is possible for the soil in the drain field to become saturated during periods of excessive water consumption by the home, reducing the ability of the drain field to process the wastewater produced.
The use of a drip system eliminates these two disadvantages of the traditional gravity-fed system.
The dosing chamber is a separate tank that accepts wastewater from the septic tank and processes it.
A pressure dosage system is what this is referred to as.
When effluent is applied consistently and at predetermined intervals, the soil is less likely to get saturated, which allows the soil to perform more efficiently while also lasting for a longer duration of time.
Homeowners should not wait until the alarm system detects a problem; instead, they should routinely follow suggested maintenance methods to ensure that the system continues to function properly for the longest period of time feasible.
It is in the best interests of the homeowner to ensure that the septic system is properly maintained.
