Purposes for which we process personal data
The RBG processes your personal data to arrange taxes for water boards and municipalities. We also use personal data to implement the Valuation of Immovable Property Act (Wet waardering onroerende zaken (WOZ)). These are statutory duties of the RBG. We use some data to be able to better assist you, such as your telephone number and e-mail address.
Right to privacy
Everyone has a right to privacy. This is why the RBG handles your data in a careful and confidential manner. The RBG does not give your (personal) data to other organisations or individuals without your permission, unless the RBG is under a statutory obligation to do so. The General Data Protection Regulation (GDPR) clearly stipulates how organisations must handle personal data. The RBG does not use your personal data for commercial purposes.
Your privacy at the counter and on the telephone
If you have any questions, you can call us, or you can stop by our counter (by appointment). We first ask for your citizen service number (BSN) and date of birth. We do this to better protect your personal data. Only then do we share confidential information. By doing so, we want to prevent the information from reaching people who are not entitled to it.
Some personal information we never give out over the telephone. This includes your citizen service number (BSN), date of birth, and address details.
If you call us at the general number 088 291 10 00, your conversation may be recorded for training and quality purposes. We delete this recorded conversation after 6 months.
We secure your data
The RBG takes the protection of your data seriously, and takes steps to prevent the following:
- abuse
- loss
- unauthorised access
- unwanted disclosure
- unauthorised modification
If you suspect that your data is not properly secured or that your data is being misused, please report this to privacy@derbg.nl.
We will keep your data confidential

Sharing personal data with third parties
The RBG provides your personal data to other organisations or individuals only when necessary for the performance of our statutory duties, a public-law duty or to comply with a statutory obligation.
