A septic tank system is a biological treatment system which retains solids and returns liquid wastes to the ground through a percolation system. In the septic tank, microbial action breaks down the solids and reduces their volume. The remaining sludge, or septage, must be removed from the tank periodically. If this is not done, solids will overflow into the percolation system and clog it. The system will then back up into the house, or flow out onto the ground, necessitating costly repairs or replacement of the system.
The helpful bacteria in the septic tank must not be upset by the addition of chemicals into the system, nor should it be overloaded with garbage and paper wastes. The DO'S and DON'TS listed below should be observed to prevent failure of your septic tank system.
