Septic tank is situated in locations where there is no access for public wastewater. Septic is made to breakdown and stock sewage received from homes and offices that would otherwise be disposed to the municipal treatment facility. Septic tank is generally constructed from concrete. But, there are various other materials which are used for septic tank like steel as well as fiberglass. Septic is constructed below the ground just outside the place whereby the waste from kitchen sinks, commodes, bathroom showers and washing machines are directly disposed. The capacity of septic tank ranges from 300 gallons to 30,000 gallons. The capacity of tank being built depends on the facility the tank serves.
In the event that the waste material goes in the septic tank the solids and liquids are normally separated. Inside the tank the waste products form three levels. The topmost layer is named the scum layer wherein the grease as well as the oil floats. The middle tier is the clear layer or the effluent stratum and then the lowermost stratum is the debris level upon which the solids are stored. Typically, in many tank system the effluent or second layer would systematically enter into the drainfield or leachfield. The septic tank has lateral tubing which set off to the drain field. The line is where the effluent will pass through and then into the drain field. The liquid that goes to the drainfield are addressed biologically by the natural flora that are found in the tank device. The ground layer or the debris tier along with the top portion or the scum part are also slowly and gradually converted biologically by the very same microorganisms and changed to the effluent part or central layer.
The waste together with the sewage that goes into the septic tank is normally destroyed and liquefied that permits it to move through the pipes that goes to the drainfield. At the drain field aerobic bacteria and anaerobic bacteria is present. Aerobic bacteria are microorganisms that need oxygen to survive while anaerobic bacteria don’t need oxygen in order to survive. These microorganisms break down the liquid to be disintegrated to harmless water and carbon dioxide that are eventually absorbed into the deeper adjacent soils. They would be converted and become reusable water that permeates into the deeper water table.
Septic tank system discharges hazardous gases which have bad odor and damaging to the environment. This was because of the by-product of the breakdown of organics with the anaerobic microbes present in the tank system. The lines and areas in the septic system have P-Traps or perhaps loops and curves. This serves to hold enough water so that the gases and foul odours will be prevented from backing up into the house. The P-Traps look likes the loops and curves which are found under the kitchen sinks.
Additionally, in the construction of the septic tank system, a pressurized system vents are provided. Normally, it runs clear through most homes which are placed on top of the roof. These vents are pipes that provide as outlets for the gases that emits foul odor. With these vents the unwanted gas are released into the air.
