A septic tank provides a traditional solution to sewage disposal needs for domestic dwellings without access to mains drainage. This tank with a capacity of 4,600 litres (1,000 gallons) is suitable for up to 17 persons.
Sewage enters the septic tank into a settlement chamber, allowing solid waste (sludge) to sink and liquid to rise to the surface. This surface liquid makes contact with oxygen and the organic matter starts to breakdown biologically.
This liquid still contains sewage but in small enough particles to be carried through the discharge outlet and into the ground (soakaway).
Comes complete with pedestrian cover and frame.
