Pay rainwater charges

  • Steuern und Abgaben

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

  • Basic information

    Since April 1, 2024, there have been 2 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 1000 m²: in future, they will receive separate notices of charges 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 property 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.

    Requirements

    • Owner:in of a property or authorized user of the property.
  • Procedure

    • For the stormwater fee, the areas on the property that are relevant for the fee must first be determined.
    • Property owners or other authorized parties are expected to receive survey forms with an overview graphic of the built-up areas of the property from 2026.
    • The determined areas of the properties will be presented in a survey form. In the survey form, the owners will be asked to confirm the accuracy of the areas determined via an ONLINE portal or to correct them if necessary.
      • You will receive a survey form by post from hanseWasser, on which the sealed area of your property is pre-determined with the help of property maps.
      • Check the survey form and provide feedback online: either confirm quickly and easily or submit corrections.
    • The survey form also includes an answer guide.
      • Advice options have also been set up to provide assistance. Contact details are provided together with the survey forms. These can also be found under "Responsible bodies" - "Contact person".
    • The roof areas with roof overhangs entered in the survey form are taken from the real estate map. The information on the built-up area was calculated from a statistically determined factor of the building floor area.
    • The complete changeover should be completed by the end of 2027.
    • You will receive notification of the rainwater charges by 2027 at the latest, in which the charge from 01.04.2024 to the current billing period will then be settled.
      • If you have any questions about the notice and billing, please contact hanseWasser.
