Septic Tanks
A septic tank works simply by acting as a settling tank for the household
sewage. The wastes pass from the house to the tank by the force of gravity.
The waste products settle to the bottom of the tank and clarified liquid
remains near the top. The clear effluent leaving the tank is directed to
an adsorption field for furthur degradation and final disposal. Anaerobic
digestion by microorganisms prevail in the lower sections of the tank..
