Revenues water board levies; budget and actual

This table contains data on the budgeted and actual revenues of the Dutch water authorities from the levies they charge to pay for their activities.
The data include both net revenues (after deduction of irrecoverable amounts and remissions) and gross revenues (all water board levies as imposed on households and businesses). The gross revenues are broken down by activity.
The water boards’ main activities include flood defence, water management (safeguarding the correct water levels for agriculture, nature, residents) and ensuring water quality (water treatment). Some water boards also manage roads and waterways.
The data included in this table have been derived from the budgets and annual accounts as reported by the water boards for each reporting year.
