Septic tanks are buried underground and hold wastewater until solids sink to the bottom, forming sludge. Oils and grease float to the top as scum. Bacteria break down these contaminants.
The liquid waste, known as effluent, exits the tank through a pipe into a drain or leach field. This soil acts as a filter to purify the wastewater even more. Click https://www.septictankarmadale.com.au/ to learn more.
A septic tank is the heart of your home’s waste treatment system. It stores wastewater from your toilets, bathtubs, sinks, and showers. It also includes your laundry. A septic tank can be in your yard or buried underground in a field or ravine.
During septic tank operation, solid waste is broken down by microorganisms and separated into layers. The top layer comprises oils and grease that float on the water. The middle layer is the wastewater with dissolved waste particles. The bottom layer is sludge, which sinks to the bottom of the tank. Microorganisms digest these materials so they can be discharged into the drain field without clogging or overflowing the tank.
The septic tank links to a drain field or leach field through pipes buried underground. The effluent (water) flows out of the septic tank into the ground, where it is treated and absorbed by soil. The drain field is often located in a large, flat area of a residential property. The septic system can be used in one- or two-chamber systems.
When the wastewater reaches the drain field, it goes through gravel and soil that further treat it. A septic tank with no drain field would overflow and produce foul odors in the backyard. The drain field is often surrounded by a buffer of trees, shrubs or grass to protect it from vehicles and equipment.
Before purchasing a home with a septic tank, you should always have the septic system inspected and pumped. You should consider asking the seller to install a riser that is at grade for pumping and maintenance. A riser is more watertight than the concrete lid and allows the system to be easily accessed for routine inspections and repairs.
To keep the septic system in good working condition, don’t flush items that don’t degrade such as paper towels, cotton swabs, dental floss, cigarette butts, medications and condoms. Do not use chemical additives such as drain cleaners, floor cleaners, paint thinners and antifreeze. Inspect the septic tank for cracks, leaks and structural damage at least once a year. Make sure the tank is sized correctly for the home.
How does a septic tank work?
The septic tank is a large concrete or fiberglass water-tight container buried underground close to the home. Its size depends on the number of bathrooms and water consumption. One end is connected to an inlet wastewater pipe; the other to a septic drain field, or leach field.
Wastewater from washing machines, kitchen sinks and toilets flows into the septic tank. Heavy masses such as feces sink to the bottom of the tank; fats and grease drift to the top; and clear liquid waste, or effluent, runs out of the outlet. A baffle wall separates the sludge from the effluent and prevents solids from leaving the tank with the wastewater.
Bacteria in the septic tank break down the waste. The partially treated effluent then flows out of the septic tank through a series of pipes into the drain field or leach field. The soil in the leach field filters and digests the liquid waste. The result is clean, odor-free wastewater that seeps into the groundwater and aquifer.
A septic system needs to be cleaned periodically. Most of the work is done by bacteria, but chemical cleaners are also used. The leach field also must be periodically inspected for signs of leaking. If the septic system is properly maintained, it should only need a regular pumping of the septic tank.
It is important not to flush chemicals or other items into the septic tank, especially if you have a garbage disposer in your kitchen. Cigarette butts, coffee grounds and diapers can all clog the tank. In addition, using a chemical tank treatment product can upset the balance of bacteria in the septic tank and damage the system.
All new septic tanks are required to have a riser and lid at grade for access during pumping, maintenance, inspections and repair. This allows the tank to be pumped out without digging up your yard. If you’re hiring a professional, they will use a truck with a giant tank that has a suction hose attached to it. The septic tank is pumped, and the sewage is transported to a sewage processing plant.
What are the benefits of a septic tank?
There are several benefits to owning a septic system. The primary benefit is that it allows people to live in areas that are far from the city sewer. A septic system also reduces costs and is more environmentally friendly than traditional sewer systems, because the septic tank eliminates the need for public sewer lines.
A septic tank is usually made from concrete, steel or fiberglass and is placed underground at the back of a property. It is linked to a drain field, which is buried in gravel trenches. The drain field serves to further treat wastewater. The water is filtered and absorbed by the soil below, which cuts pollution by removing bacteria and other harmful substances from the wastewater.
The liquid that flows out of a septic tank is known as effluent. After being treated in the septic tank, the water is sent to the drain field, where it is dispersed into the soil by pipes. This process helps to further purify the water by removing forms of nitrogen and phosphorous from the wastewater. Effluent water is then returned to groundwater.
When a septic tank is not pumped regularly, the solid waste can cause clogs in the plumbing system, resulting in raw sewage spilling onto the ground. The septic system can be damaged, and the waste can cause health issues for anyone who comes into contact with it. Regular septic tank pumping and maintenance can help to prevent this.
In addition, a septic tank cuts pollution by making use of the drain field or leach field as natural filters. This method strains wastewater before it gets into the soil, which makes the soil more effective at filtering and purifying the water. This water can then be used by local plants and wildlife to grow, which further cuts pollution.
Septic tanks are also more dependable than traditional sewer systems because they don’t rely on a network of pipes to remove the waste from the house. However, septic tanks are prone to clogs, so it’s important to be careful what is poured down the sink and toilets. These clogs can be expensive and dangerous to health, so it’s crucial to maintain a septic tank properly and avoid using items that can’t be broken down by bacteria.
What are the disadvantages of a septic tank?
A septic system is a great option for people who live in rural areas and don’t want to be connected to the city sewer line. It can also help save money on sewage bills and property taxes. However, there are some disadvantages to a septic tank as well.
One disadvantage of a septic tank is that it can be expensive to clean and maintain. It is recommended that you have your septic tank cleaned every two to six years to remove solid waste. Another disadvantage of a septic tank is the potential for damage to groundwater and nearby bodies of water. If there are leaks or a failure of the septic system, then bacteria could seep into the surrounding soil and water, which can be harmful to humans, pets, and livestock.
Septic tanks can also be a fire hazard, as they contain toxic chemicals that are highly flammable. This is a concern for homeowners who have swimming pools near their septic tanks.
Another disadvantage of a septic tank can be the odor that is released from the tank. If your septic tank is not pumped regularly, the resulting sludge can flow into your home and cause a foul smell. Regular pumping prevents this from happening by removing sludge before it enters the drain field.
If you are considering buying a home or piece of land that uses a septic tank, it is important to have it inspected before you make any purchase decisions. A septic tank inspection can help identify any potential problems with the system so that you can have them repaired before they become a serious issue.
A septic system can be a good choice for many types of homes, but it is important to keep in mind the pros and cons before making a decision. If you have questions about septic systems or would like to have a professional inspect your property, contact us today. We would be happy to help!
