Calculate and set waste water tax
If you discharge wastewater into a body of water, you must pay a tax under certain conditions. To calculate the levy, you may need to submit data and associated documents to the responsible authority.
Important notes
Prerequisites
Documents required
- Explanation of monitoring values
- Explanation of lower monitoring values or a lower amount of wastewater as well as the associated measurement results
- Explanation for small introductions
- Application for deduction of previous charges
- Declaration for the offsetting of the wastewater levy as well as the associated evidence of expenses incurred for the construction or expansion of wastewater treatment plants and wastewater plants
Please note
When calculating the number of harmful units for small discharges (less than 8 m³ per day of dirty water from households or similar dirty water), the amount of dirty water that is treated in a wastewater treatment plant that at least corresponds to the state of the art is not taken into account. For small discharges from wastewater treatment plants that do not correspond to the state of the art, the wastewater tax is collected by Hamburger Wasserwerke GmbH (HWW) with the water bill.
Furthermore, under certain conditions, the expenses you incur for the construction or expansion of wastewater treatment plants and wastewater plants can be offset against the wastewater tax you have to pay.
Deadlines
If the notice does not contain any specifications for determining the damage units, you must submit the necessary data and associated documents (declaration) to the responsible authority at least one month before the start of the assessment period. The assessment period is the calendar year.
For small discharges (dirty water from households and similar dirty water of less than 8 cubic meters per day), you must submit the data required to determine the pollutant units and the associated documents (declaration) to the responsible authority by March 31 at the latest for the past calendar year.
The amount of the wastewater tax should be an incentive for you to take better cleaning measures. The wastewater levy can be reduced under certain conditions if you declare to the responsible authority at least 2 weeks before the requested period that you will comply with lower monitoring values or a smaller amount of wastewater than specified in the notice.

Service description
The amount of the wastewater tax depends on the harmfulness of the wastewater. The harmfulness of certain pollutants and groups of pollutants is determined in harmful units. The assessment of the pollutants and pollutant groups to determine the pollutant units as well as the threshold values are listed in the appendix to the Wastewater Taxes Act.
How many and which units of damage must be taken into account when calculating the wastewater tax you have to pay is determined by the stipulations in the notice that allows you to discharge wastewater (permission under water law).
