Septic Tank

Septic Tank

RCC septic tanks make flushing of latrines possible. These RCC septic tanks are manufactured from reinforced cement concrete by spinning it which results in a dense impervious concrete with smooth surfaces. The Soil pipe from the latrine which must be equipped with flushing arrangement is connected to the septic tank. Usually the soil pipe is laid after fixing the septic tank, but its alignment and level are determined. The working of the reinforced septic tanks or concrete septic tanks is based on the chemical changes which the sludge flushed into the tank from the latrine undergoes due to action of bacteria on it. The sludge is broken into simpler chemical compounds. The gases produce escape into the atmosphere while the fluid which passes out (called the effluent) is quite harmless and can be used in the garden or for growing vegetables, or it may be run out as waste. Septic tanks require no special care. Their cleaning is required about once in three years. Care should be taken to avoid using antiseptic liquids (like phenol etc.) in the cleaning of Septic tanks, as they are harmful to bacteria and retard the chemical action taking place in the tank.
