What is a small sewage treatment plant?


Fully biological small sewage treatment plants are always used when a sewer connection and thus a wastewater treatment in a local sewage treatment plant does not seem reasonable for technical or economic reasons.
In these cases, the owner must ensure proper wastewater disposal via a fully biological small sewage treatment plant or a domestic sewage treatment plant.
As a property owner, you should make sure that the sewage treatment plant has a permit. Approved products have a valid general building supervisory approval for use as a fully biological small sewage treatment plant or an "application approval for small sewage treatment plants according to DIN EN 12566-3 with CE marking" from the German Institute for Building Technology (DIBt).
