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

Description topics

Wastewater treatment levy
The levy related to the cost of wastewater treatment. This depends on the amount of pollution discharged by households and businesses into the sewage system. Households and small businesses pay a fixed amount ('forfait').
The levy is based on a 'pollution unit' equal to the average amount of waste substances discharged per year per entity.
