Mound System Septic
In regions with shallow soil depths, high groundwater levels, or shallow bedrock, mound systems are a viable alternative. A drain field trench is included in the built sand mound. The septic tank’s effluent is pushed to the mound in predetermined dosages using a pump chamber.
As the wastewater enters the trench and passes through the sand, it is treated before being dispensed onto the native soil. While mound systems might be a suitable option for some soil conditions, they can take up a lot of room and need to be maintained on a regular basis.
What Is a Mound Septic System?
A wastewater treatment mound system is a soil absorption system elevated above the ground’s natural surface. It is common practice to use pressure-dosed mounds for primary treated effluent disposal since the effluent can be disseminated more easily into the porous sand fill.
It takes longer for the effluent to percolate through the fill because it is dispersed over a larger area of sand. To accomplish the requisite separation distance between the infiltrative surface and the site’s limiting soil condition, an elevated mound system is created above the native soil. 1 to 2 feet of treatment media make up a mound.
The major purpose is to preserve and make use of the site’s natural soil characteristics. In order for microbes in the soil and the biomat to feed on the trash and nutrients in the wastewater, it must migrate into unsaturated soil.
How Does a Mound Septic System Work?
Here, the following steps for Mound Septic System work.
- In regions where conventional septic tank systems are ineffective, a mound septic system is used. For instance, there could be too much clay in the soil for water to infiltrate quickly enough, or the water table could be too close to the surface.
- An absorption mound, a dosing room, and a septic tank are all part of the mound system. A mound septic system functions in much the same way as other septic systems.
- The wastewater from your house flows into the septic tank first while the mound septic system is in operation.
- When the wastewater reaches the septic tank, it is trapped for a lengthy time, allowing solid particles to settle. The effluent then passes through the septic tank and into the dosing chamber.
- This chamber holds the wastewater, which is pumped into a mound of soil on a regular basis. This mound provides a thick enough layer of soil to ensure that the wastewater is properly treated in a reasonable amount of time.
- During this process, the soil catches and absorbs wastewater bacteria, which are then decomposed by microorganisms. The purification process is the name for this procedure.
- Most nutrients (excluding nitrogen and some salts), organic materials, and harmful organisms are removed during this procedure. Some of the wastewater treatment capacity of the drain field is lost as the soil is flooded.
- The cleansed effluent evaporates from the soil or enters the groundwater after the purification procedure is completed. Some of the fluid is evaporated thanks to the vegetation that develops atop the mound structure. This is especially significant in areas where the water table is low.
- Mound systems are more efficient and have a longer service life than traditional systems because of these properties.
Components of Mound Septic System
A pretreatment septic tank, a pump with a small diameter pipe network, and an absorption space are among the system’s components. A topsoil cover, a layer of sandy loam, a geotextile layer, a low-pressure distribution system, and an absorption region make up the mound itself, which is a layered structure.
The following are the major components of a mound septic system:
1. Septic tank
A septic tank is a waterproof chamber that is buried beneath the ground. The material used to make it is polyethene, fibreglass, or concrete. The septic tank holds the sewage water for a lengthy time, allowing the solid particles to settle.
Sludge, greases, and oils float on top of the water as the wastewater is trapped. It may also decompose solid particles fractionally.
2. Dosing Chamber
The dosing chamber is responsible for removing wastewater from your septic tank and transporting it to the drain field. The component of a mound septic system helps to ensure that wastewater is distributed uniformly throughout the drainage region.
There are a lot of septic tank openings that lead to the drain field. If the septic system’s dosing chamber fails, the water distribution will be unequal, resulting in poor drainage.
3. Drain Field
The wastewater is sent to the leach field or drains field after passing through the septic tank for soil treatment. When new sewage water enters the septic tank, part of the previously treated water is sent towards the leaching/drainage point for further treatment.
The most well-known drain fields are made up of a series of ditches bordered with septic gravel or rock, with perforated pipes covered in soil and mesh. Drainage that enters the drain field is dissipated in part and absorbed in part by the soil.
4. Soil
The septic tank’s waste water goes into the drainage system, where it seeps into the soils. For ultimate cleansing, this soil eliminates toxic nutrients, viruses, and germs.
The availability of enough soil is critical for effective wastewater treatment.
How Much Does a Mound Septic System Cost?
Because it needs a more sophisticated design, a mound septic system is more expensive than a regular septic system. The overall cost of this system is also affected by the price of sand and the electric pump.
A mound septic tank system can cost anywhere between $9000 and $20,100. Conventional septic tank systems, on the other hand, are very affordable, ranging from $2900 to $15,000.
The typical cost of a mound septic system is between $9000 and 20,000 dollars, although it can be more expensive, especially for big systems. With an average yearly pumping and maintenance cost of around $500, wastewater treatment facilities require regular maintenance.
Mound Septic System Problems
- The mound is placed on the ground with at least one foot of dirt above the intermittently flooded soils.
- Insufficient sand to remove sewage contaminants before they reach native soils.
- On compacted or disturbed soil, the mound septic system is installed.
- The contour lines do not run into the soil treatment system.
- The plateau/swales drainage path has a soil treatment system.
- Estimates of soil permeability, structure, and texture that are incorrect
- Error in the calculation of the slope.
- Error in calculation The area where wastewater enters the original soil (absorption region/lower area). Heavy clays, which normally demand vast absorption areas and modest counter loads, can cause this problem.
- When there isn’t enough room between the two mounds when stacking them on the slope.
- Because no extra growth is detached, the plant mat penetration is reduced.
- During construction, the wastewater receiving area is compressed, reducing intrusion.
- During the winter semester, water freezes in loose pipes.
- Because the soil moisture has surpassed the plastic limit during the scarification or drilling operation, the manure receiving area becomes contaminated.
- Pump selection or float setting went horribly awry.
- Water tank leaks in various places.
- Pipe that has been damaged or disconnected.
- Septic tank collapsed due to the overuse of detergents, chemicals, and medications.
- Leaky joints or the overuse of water are both causes.
- Sink pumps and other clean water sources are linked to the mound septic system.
- Drainage from the septic tank’s impermeable portion or the roof.
- Lack of ability to pump particles from septic tanks or other large waste.
- As a result of shoddy landscaping, the area around the system becomes compacted.
Maintenance of Mound Septic System
If you haven’t yet connected your mound septic system to observation pipes, you should do it right now. Observation Pipes eliminate the need for excavation and access ports to inspect the septic tank. Encourage routine dosage chamber checks using an observation tube. There could be an issue if the water depth is progressively increasing.
Every 3-5 years, the dosing chamber and septic tank must be evacuated. Pumping intervals vary depending on the size of the septic tank and the number of residents. Each year, the septic tank should be inspected to evaluate the rate of sludge buildup. You’ll be able to pump your septic tank before it reaches critical levels this way.
To promote water uptake and prevent erosion, plant grass and other vegetative coverings on the drainage area. Planting trees or plants with a lot of roots in or near the drain, on the other hand, can clog the drain tubes. On the drainage area, do not construct or originate automobiles. This can compress the soil, reducing its ability to absorb water and causing damage to the distribution tubes.
To keep the drainage area looking neat, consider using a tiny lawnmower. However, do not place long-term fixtures like playground equipment on the septic system’s mound. e Plan the position of your drain field, container, and tank in your home’s septic system with a layout sketch.
Cut back on water usage and avoid letting waste materials like paper, plastic, and food go down the drain. Discard any corrosive, poisonous, or flammable waste, including grease and oil. These materials have the potential to cause harm to the system.
Wastewater from a residential drainage ditch should be directed away from the absorption point underneath.
Advantages and Disadvantages of Mound Septic System.
Advantages of Mound Septic System
Here, pros of mound septic system are as follows.
- It is portable and can be used in any location.
- There is no container for it.
- Unlike other types of systems, these systems are simple to install.
- The mound septic system’s area does not necessitate a lot of digging.
- It can be used on land that would otherwise be unsuitable for a standard septic tank/drainfield system. A mound system may be a suitable alternative if a piece of land is desirable from a development standpoint but a traditional onsite system will not function.
- The natural top layer of soil, which is generally the most porous, is used in the mound system. Construction damage to the site is reduced due to the little excavation required.
- Mounds may be utilized in a variety of climates and can be appealing when landscaped well.
Disadvantages of Mound Septic System
Here, cons of mound septic system are as follows.
- The installation cost of this system is rather significant.
- It is unable to install in places with restricted space.
- It is more expensive than a traditional septic system.
- If there is any leakage, you will need to partially or completely rebuild the mound.
- The expenses of design and construction are usually greater than for traditional septic tank/drain field systems.
- A more experienced installer is required for mounds than for a typical septic tank/drain field system.
- Installers must be careful not to harm the permeable topsoil layer because there is generally little permeable topsoil available at mound system sites.
- The location of mounds may have an impact on site drainage patterns and land use possibilities. Furthermore, mounds are not suited for steeply sloping areas and can be difficult and costly to restore.
- The quality of the building materials (clean sand and gravel) is critical to the system’s success or failure.
- Instead of gravity, a mound system uses a pump to transport wastewater through the system. The pump, and therefore the system, will not operate if there is no electricity, and treatment will not take place.
- Finally, heavy water consumption can overburden mounds, necessitating repairs or, in severe situations, replacement.
Mound System Septic
Mound systems are an alternative to the traditional rural septic system drain field. They are used in areas where septic systems are prone to failure from extremely permeable or impermeable soils, soil with shallow cover over porous bedrock, and terrain that features a high water table.
What Is a Mound Septic System?
A mound septic system is an alternative to other septic tank systems. It rests near the top of the ground and does not use a container for the waste. This type of septic system disposes the waste through sand, and the ground will absorb the waste.
Septic Tank Mound
Mound septic systems (also known as an above-ground septic system or a sand mound septic system), is drain field that, true to its name, sits above ground in an engineered mound.
Mound Sewer System
A mound septic system is an alternative to other septic tank systems. It rests near the top of the ground and does not use a container for the waste. This type of septic system disposes the waste through sand, and the ground will absorb the waste.
Sand Mound Septic
The mound. The mound is a drain field that is raised above the natural soil surface in a specific sand fill material. Within the sand fill is a gravel-filled bed with a network of small diameter pipes. Septic tank effluent is pumped through the pipes in controlled doses to insure uniform distribution throughout the bed.
Septic Mound Inspection Pipes
The white pvc pipes that stick up in the area of your drain field offer a “window” into how well it is operating (draining). They shouldn’t be removed but they can be cut down, level with the ground. Other white pipes may be standing above your septic tank, pump tank or close to your foundation.
Mound Septic System Installation
The original soil mound absorption area must be roughened by backhoe teeth moldboard or chisel plow the soil must be rough into a depth of 8.
How Much to Install a Sand Mound Septic System?
The sand then filters the water before it gets into the soil and groundwater. This design requires a lot of space. They’re also expensive to install because a sand mound has to be constructed. Total cost ranges from $10,000 to $20,000.
Septic Mound
The purpose of a mound septic system is to keep the waste product away from the water table. The water table has to be maintained, and a damaged septic tank is a quick way to contaminate it. The mound septic system does a great job of protecting the water table and sometimes more so than other septic tank measures.
Micro Mound Septic System Cost
A mound septic system has an average cost between $10,000 and $20,000, but may cost more for exceptionally large systems. It is important to regularly maintain the septic system, with annual maintenance and pumping having an average cost of $500.
Sand Septic
Septic Sand Is Used as an Effective Filtration System in Modern Septic Systems and Sewage Mounds. It Is Produced from Some of the Highest Quality Sand & Gravel, Which Is Washed and Finely Screened.
Raised Septic Systems
A raised septic system [or raised bed septic system] is an absorption trench system constructed in fill material with acceptable permeability placed above the natural soil on a building lot.
Sand Mound Septic System Cost
The sand then filters the water before it gets into the soil and groundwater. This design requires a lot of space. They’re also expensive to install because a sand mound has to be constructed. Total cost ranges from $10,000 to $20,000.
Mound System Cost
A mound septic system costs $10,000 to $20,000 to install. It’s the most expensive system to install but often necessary in areas with high water tables, shallow soil depth, or shallow bedrock. It relies upon an elevated mound of sand for the drain field rather than excavating into the soil.
Alternative to Mound Septic System
An alternative septic system is any type of building wastewater (also called “effluent”) drainage system that deviates from the standard septic tank. There are various ways other than a conventional septic system to divert and clean water waste from your home and safely reintroduce it back into the environment!
In this blog post, you’ll learn:
- Why some properties require alternative septic systems
