Water boards; rates of charge

This table provides data on the tariffs of the water board charges. Water boards impose these charges in order to finance their work. The main tasks are defence (flood control), water management (care for the right water level for agriculture, nature, residents) and water quality care. Some water boards also manage roads and waterways. The Water Authorities impose the water system charge, road management levy and non-task tax on four categories of tax liability: residents, owners of buildings, owners of land (unbuilt) and owners of natural areas. A water board may choose to set a separate road charge or to pay the costs of laying and maintenance from the water system charge. The same applies to the non-task-related levy. Water boards can apply tariff differentiation. This means that a water board can use different rates for the same levy for, for example, areas outside dikes and inner dikes. The table then shows an average rate. In order to calculate the average rate, the total revenue is divided by the total number of units on which the levy is levied. The data in the table are taken from the budgets adopted by the water boards prior to the reporting year. Data available from: 2009. Status of the figures: All figures are provisional at first publication. If changes occur, this is due to the availability of new or updated data. Changes by: 10 February 2022: Provisional figures for 2022 are included. The figures for 2021 are now final. The classification of water boards was last revised on 1 January 2017 and counts from that date 21 water boards. For a complete overview of water boards and mutations, see section 3: Overview of the population of water boards 2004-present. When will there be new figures? Figures for the current year will appear in February/March and the previous year’s figures become definitive.
