Description
The Graf Septic Tank, like all septic tanks, uses a ‘mechanical’ way of cleaning your sewage waste so that solids are captured and only liquid is discharged.
These Graf Carat septic tanks are divided into two by a partition wall known as a baffle. This baffle helps keep back the suspended solids in the primary chamber of the septic tank where they are trapped and can then break down into sludge over time. The effluent (liquid) flows into the secondary chamber and can then be discharged into a suitable drainage field.
The Graf Septic Tanks are available in the following sizes:
2,700l (max. 4 people)
3,750l (max. 11 people)
4,800l (max. 18 people)
6,500l (max. 30 people)
