Change your bank account number
You can change your bank account number via My Waternet. You should do this separately for tap water and water authority taxes.
Are you our customer for tap water and do you also receive your water authority tax assesments from Waternet? Then you should change your bank account number twice: once via My Tap Water and once via My Taxes.
Update your bank account number
Please go to My Waternet and log in at My Tap Water, My Taxes or both. Then change your bank account number under the tap Payment Options.
- For tap water, you will need your email address and password. You'll need a My Tap Water account for this. Don't have one yet? Create an account here (form in Dutch).
- For water authority tax, use your DigiD to log in.
Foreign bank account?
My Tap Water and My Taxes both accept foreign IBAN numbers.
