Indirect discharger
Performance specification
Wastewater is produced by domestic, commercial, agricultural and other uses of water in almost all economic and living areas. Wastewater from the commercial sector is pre-treated, if required by the area of origin, and fed via the public sewer system to the municipal wastewater treatment plants for further treatment (indirect discharger). The treated wastewater is then discharged into a surface water body.
In the wastewater source areas that provide for corresponding de minimis regulations and requirement regulations and for which only a notification instead of a permit is required for the discharge, monitoring of the discharges is carried out by expert bodies in accordance with the Indirect Discharger Ordinance. This applies, for example, to separator systems for the treatment of waste water containing mineral oil, amalgam separators in dental practices or chemical cleaning systems.
