Within the septic system is a holding tank and what this holding tank does is to hold the natural bacteria which encourages the decomposition of human waste products in an environmentally acceptable way.
The septic system is basically designed to act as an onsite system to break down and dispose of biological human sanitary waste products in a safe manner.
Parts linked to a septic system
The obvious parts that you would think of as being linked to any septic system in a regular home would probably be sinks, toilets and pipes.
Many components to the septic system may not be so obvious and are equally as important to the smooth operation of any septic system and this includes the ground itself.
Some of the various part of the system includes the septic tank the distribution box and a leach field. The bacterial actions take place inside the septic tank and the end product of this process is mostly water, sludge which is undigested material and gases. The sludge sinks to the bottom of the tank.
Baffles are contained within the septic tank and the job of the baffles is to prevent any scum that may float to the surface and any sludge the settles at the bottom of the tank from escaping out of the tank.
Any gases that accumulate are ventilated out into the atmosphere by a plumbing ventilation system. Once this process has taken place clearer liquid will flow to a small distribution box where it will be distributed to various perforated pipes.
The perforated pipes will pass the clearer liquid to a large soil surface area which is called a leach field, or field for absorption. The soil completes another task which is to act as a filter and remove any quantity of small solids that may have travelled in the liquid.
The pumping out of any sludge from the bottom of the tank must form part of any regular maintenance schedule and this sludge must be disposed of professionally.
There are a large number of systems created for all situations however having said that the septic tank and leach field is the most common and widely used.
