Abwasserabgabe berechnen und festsetzen

Do you discharge wastewater into a body of water? Then you must pay a levy to the respective federal state. You should submit the declarations (forms) required for the assessment of the levy to the competent authority.

In Germany, a wastewater tax is levied on the discharge of wastewater (wastewater and precipitation water) into surface waters or groundwater on the basis of federal and supplementary state law. The wastewater levy is collected by the individual federal states.

Citizens - including small dischargers - and indirectly discharging companies only pay the wastewater levy indirectly (via the wastewater charge or via the local authority passing it on). Only companies that have their own wastewater treatment plant and discharge wastewater pay a wastewater levy directly to the state.

The required documents vary depending on the wastewater and/or stormwater discharge obligation.

Possible documents required for wastewater:

• Declaration of discharge for small dischargers
• Declaration of monitoring values
• Declaration of lower monitoring values and the resulting measurement results
• For industrial dischargers: Application for deduction of prior pollution

Possible documents required for precipitation water:

• Declaration of discharge for precipitation water

Anyone who discharges wastewater into a body of water is liable to pay the levy.

A levy must be paid to the respective federal state for the discharge of wastewater.

The amount of the levy depends on the number of pollutant units (ZSE) determined and the underlying levy rate.

The processing time depends on the quality and scope of the applications and documents submitted.

The tax return must be submitted by March 31 of the year following the assessment period at the latest.

A wastewater levy is charged in Germany for the discharge of wastewater (wastewater and rainwater) into surface waters or groundwater.

Responsibility lies with the district and the independent city.

• As a rule, the lower water authorities are responsible for collecting the wastewater levy: districts, independent and large independent cities, Hannover region
• In certain cases, the Lower Saxony State Agency for Water Management, Coastal Defence and Nature Conservation (NLWKN) is responsible for collecting the water abstraction charge

• Declaration of discharge for small dischargers
• Declaration of monitoring values (§ 6 para. 1 AbwAG)
• Declaration of lower monitoring values (§ 4 Para. 5 AbwAG)
