From the water system levy we pay the costs of dikes, dunes, pumping stations and locks, among other things. It also covers water quality.

Here's how it works

The water system levy consists of four categories, namely:

Users

You pay water system levy users if you are a resident of a housing unit on January 1. This levy is the same for every housing unit. For the amount of the assessment, it does not matter how many residents a house has and what the value of the house is.

Want to know more about the water system levy users when you move or die? If so, see the page Moving house or the page Death.

Built owners

You pay water system levy built if you are the owner of a home or (business) property in our area on January 1. We calculate the levy by multiplying the WOZ value by the rate.

Unowned owners

You pay water system levy if you own undeveloped land on January 1. The surface area of the undeveloped land determines the amount of the assessment. We receive the information about the surface area from the Land Registry.

Unbuilt nature owners

You pay water system levy if you own natural land on January 1. The surface area of the undeveloped land determines the amount of the assessment. We receive the information about the surface area from the Land Registry.

Frequently Asked Questions

When can I expect the water tax assessment?

At the end of January, we impose assessments on residential users. Owners of homes or (business) premises will receive the assessment at the end of April or at the end of May.

Do you become a taxpayer during the year? Then you will receive the assessment as soon as possible. To impose the assessment, we depend on your municipality and the Land Registry. Only when we have processed the necessary data can we impose the assessment. It can therefore sometimes take a while before you receive the assessment.

We want to receive the assessment in someone else's name, is that possible?

Yes, you can submit a request for the next tax year. Whether we make the name change depends on the following Requirements:

  1. When it comes to user fees: the co-user must be registered at the address on January 1 of the year.
  2. When it comes to owner charges: the co-owner must be registered as owner in the Land Registry on January 1 of the year.
  3. Both the person currently receiving the assessment and the newly proposed taxpayer must sign the request.
  4. If there is a combined assessment (charges for use and for property on one assessment bill), it cannot be split. The newly proposed taxpayer must be a taxpayer for all levies listed on the assessment notice.
  5. The name change should not prevent the assessment from being collected.
