Systems with a separate septic tank are increasingly being phased out because they generate unpleasant odors and require more frequent emptying. Modern single-chamber treatment plants with oxygenation eliminate this problem.

Treated sewage is discharged into a receiving source: a drainage system, a soakaway well or a plant irrigation system (GREEN SHOWER), enabling water recovery and ecological use of resources.
