Marion County's curious interest on septic tanks has caught the attention of the builders and realtors. The basics on septic tanks were shared by the county Chief Sanitarian through an article who wrote which he distributed to the residents of Marion County.
The purpose of the said article is to give information on what one can expect from his septic tank. Underdeveloped areas can make use of septic tanks for a proper sewerage system. In order to dispose of waste matter effectively, a filter bed or a tile disposal field must be put into place alongside a septic tank.
The look of fresh waste matter is like that of soapy water and it is dark grey in color. A 150 gallon amount of waste matter is made up of around one pound of solids.
One half of the solid portion of the effluent is composed of vegetable and animal matter and the other half is made up of minerals. The vegetable and animal matter produce a 60 percent solution that does not settle while the remaining 40 turns into a suspension that settles over time.
The clearance of the effluent portions that settle and don't settle is the chief predicament in sewage treatment. A septic tank facilitates a quicker digestion and decomposition of waste matter. Grease and some of the lighter portions of waste matter create scum at the top of the tank while at the bottom, solid portions can be found decomposing.
Credits for the disintegration and decomposition that occur in septic tanks go to the aerobic and anaerobic bacteria. The bacteria cause the organic solids to putrefy into liquids and gases. A small amount of material cannot be decomposed, even after the digestion process has been completed, and it turns into sludge at the bottom of the tank.
The septic tank depends heavily on the actions of the bacteria. Quelling of the bacteria action occurs in the presence of chemicals within the tank. Chemical solutions and lye should never be used in the cleaning of drains.
A certain volume of liquid is discharged out the side of the tank when fresh sewage enters the tank and this is how liquid levels are maintained at equilibrium in a septic tank. The presence of a baffle in the inlet of a septic tank ensures that raw sewage is guided towards the bottom of the tank.
This system allows raw sewage to settle and to not be displaced out of the tank immediately and the scum is left undisturbed. The septic tank's baffle at the outlet helps achieve this purpose.
Although the discharged effluent has most of the solid matter removed, it is far from pure and has an offensive odor. A septic tank must not be used as a collection reservoir for rain water.
An average two bedroom home can be served adequately by a 500 gallon septic tank. In some of the larger homes, a 1,000 gallon tank is recommended. Once every three years, a septic tank must be cleaned out in order to ensure the production of good results.
