Detailed description
For the construction and operation of certain wastewater treatment plants, mostly used industrially, as well as for significant changes to them, you may need a separate water law plant permit. As a rule, you only need the permit for wastewater treatment plants,
- for which an environmental impact assessment must be carried out, or
- in which waste water is treated that comes from plants covered by the Industrial Emissions Directive (IED) and for which there is no permit under the Fourth Ordinance on the Implementation of the Federal Immission Control Act (Ordinance on Plants Requiring a Permit - 4. BImSchV), or
- which treat waste water from a landfill with a reception capacity of at least 10 tonnes per day or with a total capacity of at least 25 000 tonnes.
You must apply for approval from the relevant authority. You must have the approval before you start your project.
