Discharge of waste water into public wastewater treatment plants: permit

A drainage permit is required for connection to and use of the public sewage treatment plant.

The competent authority has laid down in its drainage statutes discharge conditions for the waste water in order to ensure the proper operation of the sewerage system and the sewage treatment plant. When granting the drainage permit, it shall also decide whether pre-treatment of waste water is necessary, particularly in the industrial and commercial sectors.
