If you have a water law permit for the discharge of stormwater and you want to change the discharge, you must apply for a permit change.

If you want to drain rainwater or discharge it into a surface water body, you usually need a water law permit. If you want to change a project for which you have a water law permit, you must apply to the responsible authority for a permit change.

• Rainwater is water collected from built-up or paved areas that run off.
• Surface waters include rivers, lakes, canals, streams, ditches and ponds.

The permit specifies the type and extent of use. It may be subject to additional conditions. In contrast to a permit, a permit can be revoked by the authorities

Which documents you need for your application varies depending on the type and scope of your project. In a preliminary discussion with the responsible authority, you can clarify which documents are required in your case. These are usually the following documents:

• Application form
• explanatory report
• Extract from the property map (scale 1:1,000)
• extract from the land register
• Proof that infiltration is not possible on site
• Property drainage plan (according to DIN 1986-100: 2016-12, including discharge points)
• detailed plan of the discharge point

Optionally, the following additional documents may be required:

• Power of attorney for applicant (if not permit holder)
• consent of other affected property owners
• site plan (scale 1:5,000)
• data sheet throttle
• Detailed plan (with sections) throttle
• Information, representation and calculation of the required rain retention facility (including flood proof and KOSTRA rain data used)
• Assessment of the pollution of rainwater and the need for treatment (according to DWA-A 102-2)
• analysis results

• The responsible authority has a water law permit for the project.
• The harmfulness of the rainwater is kept as low as possible given the state of the art.
• The discharge is compatible with the requirements regarding water characteristics and other legal requirements.
• Where necessary, facilities or other installations will be constructed and operated to meet these requirements.

Fees apply, depending on the nature of your project and the effort required to process it.

• You submit your application together with the necessary documents to the responsible authority.
• The responsible authority will examine your application and, if necessary, request any missing documents or information from you.
• The responsible body will examine your application from a water management and water law perspective and, if necessary, involve other bodies.
• You will receive a notice of change to your permit or a rejection notice.
• You will also receive a fee notice.

The processing varies depending on the type of project you are working on.

There is no statutory deadline. Apply for the permit change well in advance of the planned change in the discharge.

There are no special features to consider.
