Introduction of Conventional Septic System
Conventional septic systems, also known as conventional septic systems, are the most basic form of septic systems. The conventional septic tank and the absorption field, which can be referred to as the conventional soakage system, are the two main components of conventional septic systems. The drain field is another name for the absorption field.
The septic tank receives wastewater from the residence. Septic tanks are waterproof structures made of concrete, metal, or fiberglass that are used to collect wastewater. This wastewater is kept in the septic tank for long enough for three different layers to form.
The scum layer, which is made up of grease, oils, and floatables, is on top. The sludge layer, at the bottom, is made up of sediments and waste that cannot float.
Some of the trash in the septic tank is broken down by anaerobic bacteria found in the sewage.
The liquid effluent layer is in the center, and it is permitted to flow out of the septic tank via T-shaped baffles. This effluent layer is deposited on top of the absorption field.
The absorption field is often made up of a succession of trenches that allow the liquid effluent to be discharged gradually.
A porous pipe sits on top of a medium such as sand and/or gravel in each trench. The remaining pathogens, viruses, and bacteria are naturally removed when the liquid effluent slowly percolates into the medium and surrounding soil.
What Is a Conventional Septic System?
A septic tank plus a trench or bed subsurface wastewater infiltration system make up a decentralized wastewater treatment system. A single-family house or small company generally has a conventional septic system installed.
The gravel/stone drain field is an old design that has been around for a long time. The term refers to the drain field’s creation. The wastewater is routed from the septic tank to a shallow underground stone or gravel trench in this arrangement.
The trench is subsequently covered with a geofabric or similar material to keep sand, dirt, and other pollutants out of the clean stone.
When the effluent enters the soil below the gravel/stone trench, it filters through the stone and is further cleaned by microorganisms. Gravel/stone systems have a big total footprint, therefore they may not be appropriate for all home sites or circumstances.
Traditional septic systems have long been the most widely utilized wastewater treatment method. Gravity is used to treat and distribute wastewater in these systems.
They are the most affordable and need the least amount of upkeep, which is usually restricted to septic tank pumping on a regular basis.
A conventional gravity flow septic system is made up of a series of tanks or a segmented tank, which is then connected to a distribution system. Before wastewater enters the distribution system, septic tanks are used to settle sediments and partially treat it.
One of the typical subsurface drain field choices can be used for the distribution system. They are made of gravel-filled trenches, plastic chambers, or plastic tubes that are put underground to retain wastewater as it exits the tanks until it can soak into the soil.
The soil treats the majority of the wastewater. Soil grains remove sediments including organic debris from wastewater. Organisms in the soil decompose the sediments and destroy the bacteria as well as pathogens in the wastewater.
The size of the tanks as well as the distribution system is determined by the quantity of bedrooms in the home with the kind of soil in which the distribution system is built.
How Much Does a Conventional Septic System Cost?
When considering septic system types and cost, conventional septic systems are less expensive than mound systems, although prices are still determined by system size, soil characteristics, and location.
The conventional septic system cost is influenced by these factors. A permit is usually required before installing a septic system, which costs between $250 and $1,000 on average.
Pricing is influenced by where you are. A traditional septic system costs between $2,000 to $5,000 on average in the Midwest, but between $4,000 and $15,000 in locations with greater labour and material prices.
On its own, a septic tank can cost anywhere from $500 to $1,800, depending on its size. The typical cost of piping and other materials is between $100 and $200.
Every one to three years, inspections are required, and they cost between $200 and $600 on average. Pumping the system on a regular basis is also required, which costs between $200 and $400.
The cost of installation varies between $2,000 and $6,000, depending on the soil type, the size of the house, and other criteria. Based on a three-year pump-out, septic tank maintenance costs around $75 each year. The expense of more regular maintenance rises.
Conventional Septic System Maintenance
For maintaining a traditional septic system, the conventional septic tank should be pumped a minimum of every 2 to 3 years. The size of the tanks, the number of people living in the house, and their waste disposal practices all influence how often they need be pumped.
In general, so that it can receive wastewater from the home, the distribution area should be shielded from excessive rainfall runoff.
Keeping a grass cover over the soil distribution system will aid in water removal from the soil.
The system is set up to handle a certain amount of water. It is necessary to repair leaking faucets and toilets. Low-flow devices will assist in reducing the volume of effluent.
In a septic system, a lot may go wrong. The water in the drain field will frequently overflow if the tank becomes blocked or full. This will cause unclean water to overflow your yard.
Household drains, such as those in your sink or toilet, will begin to back up and clog once the flooding begins. As a result, it’s critical to have your traditional septic system inspected and cleaned.
Septic tanks should be drained every three to five years at the absolute least. Septic pumping is a service provided by some experts. These will remove all of the fluids, sludge, and grease that have accumulated in your septic tanks over time.
Putting any type of chemical in your wastewater is one of the things you should avoid doing. Such chemicals can destroy the microorganisms in the septic tank, preventing solid waste from being dissolved.
Non-biodegradable elements, on the other hand, should not be allowed to run through your pipes. Bacteria are unable to break down these compounds. Solid objects can block your pipes, reducing the ability of your septic tank to adequately filter wastewater.
One must also stop letting grease, as well as oil, go down the sewer in the kitchen. Throw that in a container and dump it in the trash bin to dispose of it properly of trash.
Septic tanks filter grease by converting it to scum and depositing it on the surface of the wastewater, but they can still block your pipes with time. Furthermore, too much oil in your septic tank will making filtering more difficult than usual.
The cost of repairing a septic system is higher than the cost of maintaining and cleaning it. Make it a priority to follow these recommendations to the letter, since doing so can help you avoid problems.
Your septic system, like every other component of your home, requires regular maintenance. You may not be able to see how the septic tank works, but you must understand that it does far more for you than you realize.
Aside from having your drains run more smoothly, a septic tank keeps your home free of harmful germs. Make careful you maintain your septic system.
Advantages of Conventional Septic System
Here, the pros of Conventional Septic System
- Easy to care for
- Low operating costs
- There is no need for power.
- Conventional systems break down waste without the need for chemicals or a power source, making them better for the environment.
- There are several types of traditional septic systems available, including aerobic septic system vs conventional, concrete, fiberglass, and stainless steel septic systems.
- This allows you to select the optimal solution for your requirements.
Disadvantages of Conventional Systems
Here, the cons of Conventional Septic System
- Cannot be put in sensitive regions or on as many different types of soil as aerobic systems can.
- It generates lower-quality effluent than aerobic systems.
- Clay soils, shallow soils, rock, soils that get saturated during rainy parts of the year, or soils with a high water table cannot be placed with conventional gravity flow septic systems.
- A two-foot buffer must be maintained between the distribution system’s bottom and saturated or restricted soils such as thick clay or rock.
- Sewage backup poses significant problems in the house, impacting everything from toilets to sinks to showers.
- It is imperative that you address any leaks or broken pipes as soon as you become aware of them.
- It’s a huge loss for your septic system and may lead to a lot of damage to your home. Ruptured pipes are frequently the result of digging or tree roots.
- If the traditional system pipe isn’t adequately maintained, it will rust.
- Corroded pipes are more likely to fail, allowing the septic tank to leak.
