How does waste water flow through a septic tank?
How Waste Water Flows Through Your Septic Tank. The waste in your septic tank separates into layers. The heavy solids fall to the bottom where they decompose and form sludge, while the light material such as fat and oil floats to the top and forms a scum layer. Wastewater is sandwiched between these two layers.
What is a septic tank?
A septic tank acts as a settling chamber where waste from your house separates from the wastewater before this water flows into the drain field. With time, the solid waste left behind in the septic tank accumulates and can inhibit the settlement and separation process.
Why is my septic tank drain field damaged?

One of the most important things that you need to do to ensure that you keep up with septic tank maintenance is to keep records.
How deep are septic drains?
A typical septic drain field (see Figure 1), also known as a leach field, is a series of perforated pipes that are set in trenches and buried with aggregates (½- to 2½-inch gravel or ½- to 4-inch rubber chips) and soil. These drain lines are at a minimum depth of 6 inches and are typically 18 to 36 inches wide. The individual drain lines will usually be 8½ to 10 feet apart (see Figure 2). It is important to note here that each drain field system will vary from the next. It is important that the homeowner have a detailed layout of their system (giving the locations and dimensions of individual components) for their reference.
How does a septic system work?
Understanding how a septic system functions is essential to making sound decisions about how to best landscape over the drain field. A standard septic tank will separate solids from liquids. The liquid effluent, or wastewater, will then flow from the tank into a series of drain lines that allow the effluent to slowly percolate down through ...

How deep are drain lines?
These drain lines are at a minimum depth of 6 inches and are typically 18 to 36 inches wide. The individual drain lines will usually be 8½ to 10 feet apart (see Figure 2). It is important to note here that each drain field system will vary from the next.
What are the most common trees that are damaging drain fields?
Trees with very aggressive root systems that should be avoided include willows, red and silver maples , beeches, birches, elms and poplars. Some trees with less aggressive root systems include cherries, crabapples, dogwoods, hemlock and oaks. To reduce the associated financial risk and emotional stress of a failed system, plant trees at least as far away as their estimated root spread at maturity. There are two methods used to estimate tree root spread. One rule of thumb is that roots extend out from the tree two to four times the diameter of the canopy. Another is that tree roots spread out one to three times the height of the tree. These estimates should be considered a bare minimum, and to reduce the risk, the trees should be planted even further away from the drain field.
What are the plants that drain in South Carolina?
Shallow-rooted herbaceous plants refer to flowering annuals and perennials (including bulbs), turfgrass, weeds and many groundcovers. As previously mentioned, these plants are unlikely to clog and damage drain lines. Many of our native grasses in South Carolina as well as non-native grasses are well suited for use in a drain field planting. Just remember that larger plants typically have larger root systems, so tall grasses like Miscanthus spp. or pampas grass are definitely not recommended for use in this instance. Mixes of wildflowers, bulbs and grasses provide a suitable, attractive vegetative cover.
How does a septic system work?
Septic systems are designed to break down organic waste from the home, separating the waste into liquids and solids. While the solid sludge that forms in the bottom of the tank needs to be pumped out at scheduled intervals, the wastewater can be treated and reused as irrigation for crops or simply released into a septic field that typically consists of perforated piping, set in gravel trenches, and buried about 1 to 2 feet underground.
Can a deck be installed over a septic field?
As noted above, structures are a bad idea for septic fields and can’t be installed in these locations. Many people try to figure out a way around this, suggesting floating decks, small sheds, and even simple gazebos to help block out the sun, but each of these additions pose a risk to the septic system. Decks are too heavy to be safely installed over a septic field; they also block access to the system while preventing the growth of grass and other beneficial vegetation that reduces the harmful effects of erosion.
Can you put a tennis court over a septic system?
Not only does the addition of concrete prevent the process of evapotranspiration, but it also adds a significant amount of weight that could cause the septic field pipes to collapse.
Can a septic field be used for play?
Kids can make great use of the open space provided by the septic field, so it may seem like a great idea to install a permanent or semiper manent play structure, but this can lead to all kinds of problems. Large play structures tend to be too heavy, putting pressure on the septic field and potentially bending or breaking the pipes that are only a foot or two under the ground.
Do septic fence posts support weight?
With the proper placement, the weight of the fence is fully supported by the posts so that it doesn’t cause undue stress to the septic system. Also, make sure that the system can still be accessed for maintenance when necessary.
Can an above ground pool cause a septic system to be clogged?
The pool doesn’t just block oxygen from reaching the septic pipes, halting evapotranspiration, but the weight of the pool, especially when it’s full, will likely crush the pipes and back up the entire septic system.
Can trees break septic pipes?
Trees, shrubs, flowers, and other plants with deep or expansive root systems can interfere with the functionality of the septic system and may even wrap around the septic field pipes, trapping the septic effluent and causing flooding. In particular, large tree roots are known for their widespread root systems that can break through rock, pavement, and even house foundations, so it shouldn’t be a surprise that these plants are capable of crushing the septic system pipes.
Can you drive over drain fields?

What is the name of the tank that holds the water in the soil?
A septic system is usually the answer. A septic system consists of a tank to hold the solids and initial rush of wastewater plus a drain field, also known as a leach field or leach lines, to carry the water out to soak into the soil. The septic tank holds the solids, which settle to the bottom, and bacteria begins breaking it down.
How does a septic tank work?
The septic tank holds the solids, which settle to the bottom, and bacteria begins breaking it down. Grease rises to the top of the tank.

According to InspectAPedia, up to 36 inches of loose soil is spread over the top of the gravel and pipes.
What is the purpose of a drain field?
The drain field's gravel bed and covering soil are designed to allow the water to seep into the soil, where beneficial microbes feed on the nutrient-rich wastewater and clean it. In addition, excess water evaporates from the drain field, leaving the contaminants behind.
Why does my septic system sink?
If the surrounding soil cannot absorb the excess water, it will puddle around the pipes, and eventually, that section of the septic system may actually sink, or the soil may wash away and give the field a sunken appearance. Soil compaction is also an issue.
How to determine septic field size?
