Table description


This table contains data on the tariffs of the water board levies.
Water boards impose these levies as remuneration for their legal tasks. The most important legal tasks are flood defense, water management (ensuring the right water level for agriculture, nature, residents) and ensuring water quality. Some water boards also manage roads and waterways.
The water boards impose water system levies, road levies and non-task-related levies (till 2015) on four categories of taxpayers: residents, owners of buildings, owners of land (unbuilt) and owners of nature sites. A water board can choose to impose a separate road levy or to pay the costs of road management and maintenance from the water system levy.
Water boards can apply tariff differentiation. This means that a water board can use different tariffs for the same levy for, for example, areas outside dikes and inside dikes. If this is the case, the table shows an average rate. To calculate the average rate, the total revenue is divided by the total number of units on which the charge is levied.
The data included in this table have been derived from the budgets as reported by the water boards prior to each reporting year.

Data available from: 2009

Status of the figures:
The rates for the year 2021 are provisional, rates over previous years are definitive.
All provisional figures are subject to adjustments based on new or updated source material.

Changes as of 26 February 2021:
The provisional figures for 2021 have been added.
The figures for 2020 are definite.

When will new figures be published?
The new figures from the water board budgets are published in the first quarter of the financial year.
The figures can be adjusted on the basis of the availability of new or updated source material. In general, the adjustments are small. The adjustments are made at the moment a new annual figure is added to the series.
