How does it work?
The Imhoff septic tank is a primary treatment for the sedimentation of coarse solids present in the waste. The system is composed of two compartments; in the first sedimentation step, the waste, gaining speed, can make the solid part settle. Then the solids are collected in the lower compartment where they will be digested anaerobically by the present bacteria. It is recommended( when the black and grey waters are separated) to install a degreaser upstream of the Imhoff (where to send only grey waters) that will improve the sedimentation performance of the latter. Do not direct rainwaters into the system.
