Solid material overflowing into the soil absorption area should be avoided at all costs. It is this solids overflow that clogs soil pores and causes system to fail. two main factors cause solid material to build up enough to overflow: (1) bacterial deficency, and (2) lack of sludge removal.
Bacteria MUST BE PRESENT in the septic tank to break down and digest the organic solids. Normal household waste probides enough bacteria to digest the solids UNLESS any harm is done to the bacteria. Bacteria are very sensitive to environmental changes. Check teh lables of products you normally use in home. Products carrying harsh warnings such as "HARMFUL OR FATAL IF SWALLOWED" will harm bacteria.

People rarely think of the effect of these products on the septic tank system when the products go down the drain. What kind of effect to you think anti-septics have on your septic tank?
Bacteria must be present to digest the
scum. If Not digested, the scum will accumulate untill it overflows, clogging the soil absorption area.
The sludge in the septic tank - inorganic and inert material - is not biodegradable and will not decompose. If not removed, the sludge will accumulate until it eventually overflows, again clogging the soil absorption area.
