Septic tanks allow homes to be self-sufficient with their waste treatment, rather than relying on the local sewer system. These systems cut pollution by filtering wastewater before it enters soil and helps local plants and wildlife.
Heavier solid waste sinks to the bottom of the tank to form sludge while lighter waste floats to the top to become scum. Anaerobic bacteria break down organic waste pollutants in the septic tank. Visit https://septic-guys.com/ to learn more.
A septic tank has a lid that covers an opening in the top. The tank also has an inspection port or manhole in the middle of the tank that waste removal professionals use to access the tank. The septic tank should be pumped regularly. The frequency depends on the size of the household and the capacity of the tank. Generally, the septic tank should be pumped every three to five years.
When you flush your toilet, wastewater is carried from the house plumbing to the septic tank through a sewer line that slopes toward the tank. The wastewater is held in the septic tank until bacteria break down the solid waste particles and the liquid layer of wastewater is separated from the thick sludge. The sludge layer is comprised of oils and grease that float on the surface of the wastewater and anything else that is heavier than water. The septic tank also has baffles that help the layers separate.
Once the septic tank is full, the sludge layer will start to rise over the water layer. The tees in the septic tank are designed to prevent this from happening, and hydraulic pressure is used to push the wastewater out of the septic tank into the absorption field (or lateral field). The septic tank should have inlet and outlet tees that are designed with a screen or filter to block large particles.
Pumping a septic tank removes the sludge from the tank, and it also removes the gases that are produced by the bacterial process. This is very important as the gases can be dangerous to humans and cause a terrible odor. The septic tank should be inspected at least once every three to five years by a licensed septic tank contractor.
Having your tank pumped will also extend the life of your septic system. If you don’t have the tank pumped frequently enough, the sludge layer can build up and block the inlet and outlet baffles, which can lead to a clogged drain field. Clogged drain fields can lead to wastewater backups in your toilets and sinks, which is very bad for the environment and very unpleasant for homeowners. Pumping the septic tank will also prevent the growth of toxic bacteria in the drain field that can enter your home through your plumbing.
Inspection
Septic systems are the primary means of wastewater treatment for homes and other buildings that cannot be connected to a city sewer line. The septic tank and the surrounding soil absorb the household wastes through natural processes and decomposition. The septic tank is the first step in this process, and it requires regular maintenance in order to function properly.
The waste that comes from your toilets, sinks, laundry and kitchen drains runs through a main sewer line that slopes toward the septic tank underground. From there it enters the septic tank where it is processed through natural and technological methods. Solids settle to the bottom of the tank, while oil and grease floats to the top. The water that remains in the middle is then pumped into an absorption field in your backyard where soil bacteria and sometimes a sand filter complete the treatment of the wastewater.
This system is very effective and allows households to avoid the contamination, public health nuisances, odor, and expense of connecting to a city sewer. While this may seem like a gross topic to discuss, it is important for anyone who lives in a home with a septic tank. Generally, septic tanks need to be pumped out about once every three to five years. During the pumping process, the technician will check for signs of leaks, cracks, and other issues that may lead to failure of your septic tank or the leach field.
When the time comes for a septic tank inspection, it is best to have an experienced professional perform the assessment. They will look for any visible signs of damage and will be able to determine the approximate age of your tank. During the process, they will also take the opportunity to assess other components of the septic system including the pump and riser. In addition, they will be able to provide a list of recommendations regarding any potential maintenance that should be performed. These suggestions will help keep your septic tank in good working condition for as long as possible. Having an inspection done can save you money in the long run by catching any problems early on, before they cause major problems for your septic system.
Riser & Lid
Every time you flush a toilet, wash clothes, or take a shower, the waste leaves your house through the interior plumbing and flows down a sewer line that slopes toward your septic tank. This is where the wastewater gets its first treatment.
A septic tank is an underground, watertight container made from concrete, polyethylene or fibre glass. It provides primary wastewater treatment through natural processes and bacteria that break down solids and organic material. It then pipes partially purified effluent into a drain field where natural processes treat and disperse the rest of your wastewater.
The septic tank has compartments that separate the solid waste into different layers. Heavy solids like feces and toilet paper remain in the bottom “sludge” layer. Fats, oils and greases float to the top “scum” layer. Microorganisms digest the sludge and scum. The result is liquid wastewater that exits the septic tank through an outlet pipe and enters the soil drain field.
These tanks need to be pumped out occasionally, but this is not as often as one might think. As long as the bacteria and yeasts that break down the waste are healthy, it can be years before a septic tank needs to be emptied.
Most septic tanks have an access port or lid at the top of the tank that can be lifted to allow waste removal professionals to pump your septic tank. Some tanks have a riser that is installed at the same grade as the access port. This makes it much easier to pump, maintain and inspect your septic tank without having to dig up your yard. A riser also helps to protect the septic tank from groundwater which could overwhelm your system with excessive wastewater. A riser should be installed on all new septic systems and on existing tanks that pass inspection.
Tanks with Pumps
A septic tank system is a basic form of an onsite sewage treatment facility (OSSF) that processes wastewater in a home or building that’s not connected to the mains sewage network. It works by collecting excreta and waste from household plumbing in an underground watertight container that’s typically rectangular or round, made from fibre glass, plastic or concrete. The septic tank has compartments to separate solid particles (sludge) and liquid wastewater into distinct layers.
These layers are separated by a T-shaped outlet that prevents the sludge layer from travelling into the drain field area of the property. Solids are decomposed by natural and mechanical means inside the septic tank to become inert waste material that’s then pumped out of the septic tank into your septic system or soil drain field for final treatment.
A typical septic tank will also have inlet and outlet tees that extend down into the water below the scum layer. These tees allow hydraulic pressure to be applied each time you use your toilets, showers, sinks and drains. This creates a force that moves the septic tank water up to and out of the absorption field each time you flush or run water in your house. This prevents any solids from making their way into the absorption field which would clog and reduce the effectiveness of your septic system.
In addition to these tees, some septic tanks will have an effluent pump. This is a small electrical water pump that is suspended in the tank and has a float switch to operate it. The float switch will activate the pump when the septic tank level rises to a certain point. This will then pump the septic tank wastewater into the septic system or septic drain field and then into the ground.
