Pay rainwater charges

Would you like to know how high the fees for rainwater are and how they are calculated? You can find out more here.

Since April 1, 2024, there have been two changes to the billing of wastewater charges.

  • Firstly, the fees have been adjusted.
  • Secondly, the fee model has been changed.

There are new features for property owners whose sealed surface area is less than 1,000 m²: in future, they will receive separate fee notices for wastewater and rainwater (stormwater). The so-called wastewater fee will no longer exist in future

The drainage fee is made up of 2 parts for all properties:

  1. The discharge and treatment of wastewater.
  2. The discharge and treatment of rainwater (precipitation water).

Rainwater is water that is discharged from the properties into the sewer network.

This rainwater charge is calculated according to the size of the built-up and paved areas and their type of paving, provided they are connected to the sewer system. These can be roof areas, paths or courtyard areas, for example.

From 01 April 2024, the disposal of rainwater will cost EUR 0.83 per square meter of sealed surface. This is 0.03 euros more than before.

The fee adjustment applies for the period from April 1, 2024 to December 31, 2026.
