Septic Tanks: How They Work
The illustration alongside shows a typical septic tank arrangement. Key elements:
A - Wastewater and sewage from the property is fed through to the septic tank.
B - The septic tank (click for a closer look) allows the solids to settle out at the bottom. The tank must be emptied out periodically, typically once a year.
C - The absorption field (or ‘soakaway’) is a critical component, as it allows the untreated liquid element of the sewage to soak away underground where it is dispersed naturally.
