Prerequisites
You must ensure compliance with legal requirements regarding wastewater treatment through a contract with the operator of the private wastewater plant.
Documents required
- Informal application for exemption with further information on the type of wastewater (quantity, ingredients, place of origin)
- Excerpts from the contract documents between you and the operator of the private wastewater system
Please note
For those industries and activities in which pollutants are to be expected in the wastewater that are not sufficiently cleaned in a municipal sewage treatment plant (e.g. chemical industry, paper production, metal processing, use of cooling water), the legislature has set requirements in the respective industry-specific appendices to the Wastewater Ordinance. In order to comply with these requirements, special measures and wastewater pretreatment systems are required to reduce the amount of pollutants so that the wastewater can then be treated without harm in a public or private sewage treatment plant.
Deadlines
No. You must have the exemption before you begin the initiation process. You should therefore submit the application well in advance of the intended start of your project .
