How does a septic tank work?

Briefly:
A septic tank captures and holds sewage, allowing the solids in the sewage to settle out and discharging the liquid effluent into an underground soakaway system.
The size of the septic tank needs to be matched to suit the level of usage it will encounter, which depends on the number of occupants in the property and levels of use.
After a period of time, the sludge created by the settled-out solids will start to fill up the septic tank. It will need periodic emptying.
